feat(web): SVG sparklines + 3D isometric mood cube (v0.20.4)

Import the updated Claude Design prototype's SVG sparkline system + 3D graph,
replacing the unicode-char sparklines:

- per-PAD-fader vertical SVG strips (stripPoints, 26x132 beside each bar — time
  down Y newest-at-bottom, value on X, gradient-faded, dot at newest); also
  answers the earlier "next to each meter" ask
- relation-row horizontal SVG sparklines (sparkPointsH, 56x13, auto-scaled,
  gradient + end dot) — fixed-width, so the old unicode overflow onto the n
  column can't recur
- mood-orbit reworked from a 2D P×A scatter into a 3D ISOMETRIC P×A×D cube
  (proj3: P right-down / A left-down / D up, 2:1 iso, scale 26, reverse-derived
  from the design's now-point + verified) with the trajectory, a pulsing
  now-marker, and a drop line + floor-shadow ellipse for depth
- gradients in one hidden <defs> svg; removed the orphaned sparkline()/_SPARK

Contract amended. Verified: pytest tests/test_web_* (84) + node Playwright
(injected 24-sample history — 3 PAD strips + 4 relation sparklines + the 3D
cube trajectory/drop/floor all render; gradients resolve).

+## Recent decisions (archived)
+
+The 2026-05-20 → 2026-05-29 cluster: the original debug-TUI/web build era, before the 2026-06-14 Bifrost-provider second identity. Archived 2026-06-18 (one event; per-entry stamps omitted for the batch).
+
+- `[2026-05-20]` Project name **Ratatoskr** (squirrel on Yggdrasil — runs up and down carrying messages). Earlier candidate Andvari demoted on the cursed-ring association.
+- `[2026-05-20]` **Separate repo, separate dev team.** Operator's call; the in-tree-at-Worldtree/tools/ alternative was considered and rejected to dogfood the API boundary.
+- `[2026-05-20]` **No Worldtree-source imports.** Spec-only dependency. Triple version-skew mitigation: spec-pin in pyproject.toml + recorded-SSE snapshot tests + conformance smoke. Initial pin: `55101e909abcd2219833266b6f905c5bc956e0f0` (Worldtree v0.19.0). See `docs/SPEC-PIN.md`.
+- `[2026-05-20]` **Textual** (not rich+prompt_toolkit). Driver: debug observability is the primary purpose, and a multi-pane dashboard with persistent side panes + independent scrollback is structurally application-shell-shaped. Volva consulted via cross-frontier second-opinion and converged on the same call.
+- `[2026-05-20]` **`httpx-sse`** for SSE consumption. The server emits composite `{turn_id}:{seq}` `id:` lines (Worldtree INV-014) load-bearing for SSE-resume; hand-rolled `data:`-only parsing (the skaldsong pattern) silently drops these. Ratatoskr becomes the reference Python SSE-resume implementation.
+- `[2026-05-20]` **Persona-pane PII posture: label-don't-refuse.** `persona.log` is process-wide; pane title flips between `[Persona — PROCESS-WIDE]` and `[Persona — session <id>…]` based on whether log lines carry session_id. Refuse-against-non-local was considered and rejected as paternalistic.
+- `[2026-05-20]` **Server-stdout pane: opt-in via `--server-log <path>`.** No auto-detection of well-known paths.
+- `[2026-05-20]` **Two-stage Ctrl-C.** First cancels in-flight turn server-side; second exits app. Ctrl-D bound to immediate exit.
+- `[2026-05-20]` **Single-session-per-launch + startup picker.** No in-app `/switch`. CLI flags `--session <id>` and `--new` for scripted use. Session identity always visible in Textual footer.
+- `[2026-05-20]` **Markdown rendering default-on; `--raw` opt-out.** Don't pre-design `--no-stream-formatting` (Volva: add only if streaming-markdown rendering is empirically ugly).
+- `[2026-05-20]` **Non-interactive `--send` mode.** Single SSE consumer module, two presenters (TUI + stdout). Keeps Ratatoskr honest as an API consumer; useful for CI / scripted probes.
+- `[2026-05-20]` **First contract: `ratatoskr.sse_client`.** Bundles `stream_turn` + `reconnect_turn` + `cancel_turn` + private `_parse_sse_id` into one module — the SSE-resume flow is coupled (cancel needs `turn_id` from the SSE wire `id:`, reconnect re-uses the same parsed `SseId`), so they share a contract. Hard invariant INV-002 makes the composite `{turn_id}:{seq}` `id:` parsing load-bearing — closes the foot-gun the design-brief §3 names (hand-rolled `data:`-only parsing silently drops the `id:`).
+- `[2026-05-21]` **Contract converted to issue-scoped (issue #1).** Frontmatter shape switched from module-scoped (`module:`/`purpose:`) to issue-scoped (`target_module:`/`scope:`/`prd:`) per CONTRACT-FORMAT §2.1.I. `prd:` block pins to issue body hash. **Known parser stale-ness**: `contract_parser.py --validate` ERRORs on issue-scoped frontmatter — CONTRACT-FORMAT §2.1.L H10, a documented Brokkr-side follow-up. Parser is a canonical sync, so we do NOT patch it locally. Treat parser ERROR-on-issue-scoped as expected until canonical bumps. (later retired — see 2026-06-15 canonical-sync entry.)
+- `[2026-05-21]` **Default issue-tracker labels seeded** (17 total). Sleipnir gating, triage, type, resolution, Ratatoskr-specific area labels (sse-client, tui, cli, observability).
+- `[2026-05-21]` **Volva paraphrase + code-review across all 4 issues — calibration consistent.** Paraphrase rounds flag 3-5 contract ambiguities per issue; code-review rounds flag 3-8 code-vs-contract drifts after TDD-passing implementation. The post-TDD code-review consistently catches three classes of gap the test-author's hypotheses don't cover: PRE-assertion boundary drift, exception-payload truncation / never-rendered-to-user observability misses, and "tested the state but not whether the user can see it" gaps.
+- `[2026-05-21]` **Manual smoke is load-bearing — found a real defect tests couldn't.** First wire-level smoke against personal Worldtree (post-TDD, post-Volva-code-review on #4) revealed httpx's default 5s read timeout killed the SSE connection mid-stream during mimir's thinking phase (~30s LLM latency >> 5s read timeout). The unit/contract test infrastructure (respx-mocked SSE wire) doesn't model real LLM latency, so the gap was invisible at the test layer. Fix: caller-owned `httpx.AsyncClient` constructed with `timeout=httpx.Timeout(connect=10.0, read=None, write=10.0, pool=10.0)`; defense in depth: `sse_client.stream_turn` ERROR_ROUTING catches `httpx.ReadTimeout` → `SseConnectionDropped`. **Lesson: keep manual-smoke step in the per-issue cadence; mock-only validation is insufficient for streaming-against-real-server code.**
+- `[2026-05-22]` **Issues #5/#6/#7 filed: per-user-agent support + TUI-startup-visibility + mid-stream-robustness.** Discovered during 2026-05-22 mimir TUI conversation: long completion crashed with `JSONDecodeError("Expecting value: line 1 column 1 (char 0)")` from `json.loads('')` on an empty-`data:` SSE frame (→ #7). Earlier same day, `ratatoskr --new --agent lofn` failed with 422 `end_user_id_required` → #5. #6 was a corollary observation (TUI alt-screen masks the diagnostic).
+- `[2026-05-22]` **Issue #8 (startup agent picker) filed.** `GET /agents` exists in the vendored spec; returns `agent_id`/`name`/`description` + optional fields. `--agent` becomes conditionally optional. Composes naturally with issue #5.
+- `[2026-05-22]` **Issue #7 implemented via TDD + Volva-code-reviewed.** First issue with zero drift findings from Volva code-review — TDD caught all runtime behavior. Hypothesis: the tighter the contract + smaller the code surface, the more Volva's role shifts from "catch behavioral drift" to "tighten observability + wording".
+- `[2026-05-23]` **Issue #6 (TUI startup error visibility) implemented via TDD + Volva-code-review (two rounds).** Restructures `run_tui` lifecycle: `_resolve_then_run` async helper opens AsyncClient, does pre-flight resolution, routes errors to stderr BEFORE alt-screen opens. Two Volva rounds confirmed multi-round value (round 2 found things round 1's amendments didn't anticipate; strictly test-precision, no behavioral drift).
+- `[2026-05-23]` **Issue #5 (`--end-user-id`) implemented via TDD.** Three modules touched. `create_session(client, agent_id, *, end_user_id=None)`; CLI flag with non-empty validation; threading through `_amain` and `_resolve_then_run`.
+- `[2026-05-23]` **Worldtree-dev consult landed authoritative consumer-API guidance** (althing thread `01KSBARG2B8M8C82H6AJGJWX1B`). Takeaways: `end_user_id` is a free-form partition key; no programmatic `requires_end_user_id` discovery; subject:{type,id} migration locked but not shipped; spec pin (v0.19.0) is 3 minor versions stale; send a User-Agent header; `agents.call:lofn` scope needed for lofn smoke; `GET /agents` requires no special scope.
+- `[2026-05-23]` **v0.2.1 layout fix: dock-anchored TUI chrome so Input never moves.** Cause: auto-stacked vertical flow shifted Input when thinking-current toggled visibility. Fix: dock chrome to screen edges; transcript absorbs reflows internally via scroll viewport. **Operator-confirmed "a lot better" interactively. Pure UI fix; tests pass without modification. TUI-layout patches are "ship + operator verifies" — TTY is the load-bearing test surface; respx + Pilot mocks can't catch screen-relative positioning bugs.**
+- `[2026-05-23]` **Issue #12 (presenter contract semantics amendment) implemented via TDD.** Thinking deltas render as ONE coalesced growing line (CLI) / one closed RichLog entry per run + live Static widget per-delta (TUI), not 50 lines per turn. Introduced stateful per-turn presenters: `CliPresenterState` + `TuiPresenterState`. Editorial promotion: load-bearing = Text/Done/Error/Cancelled (no prefix); demoted telemetry = WorkerPhase/Thinking/TextBoundary/ToolStart/ToolResult.
+- `[2026-05-23]` **Forward direction: Ratatoskr will require `end_user_id` for EVERY access before too long.** Operator's call. Reasoning: even Tier 1 foundational agents that don't *require* `end_user_id` server-side currently fall back to a `_no_end_user` sentinel partition — effectively pollution. **Cross-frontier alignment (worldtree-dev ack, althing `01KSBD9FPMCWJMBXNNS4B3MYBS`):** the platform side agrees the fallback is a substrate accommodation, NOT a consumer model. Ratatoskr's forward posture pre-empts a future tightening. File a ratatoskr issue when scheduling the change (untracked by operator choice for now).
+- `[2026-05-24]` **v0.9.0 live Markdown rendering in TUI transcript.** Replaces v0.8.2's drop-Markdown patch. Transcript switched from `RichLog` to `VerticalScroll`; each turn's response lives as a single `Static` widget whose Markdown content is updated as Text deltas arrive (no post-Done re-render, no double-print). `--raw` bypasses Markdown.
+- `[2026-05-24]` **v0.10.0 debug-pane audit logging surface.** Every SSE event arrival lands as one debug-pane line (timestamp + sse_id + event-specific summary). Token-rate Text/Thinking deltas are aggregated into per-turn counters surfaced in a turn-summary line. Also: state-machine transitions, cancel POST lifecycle, app bootstrap, ctrl-c actions, wire-error exception class+body all logged.
+- `[2026-05-25]` **Worldtree #204 / v0.28.0 integration (v0.11.0 → v0.13.0).** Three-bump arc for `affect_update` SSE event + `GET /agents/{id}/persona_state` endpoint. v0.11.0 wire layer (AffectUpdate dataclass + parse + Event-union member); v0.12.0 read-side client (`get_persona_state` + typed errors PersonaNotConfigured/AgentNotAvailable/AuthScopeDenied); v0.13.0 TUI surface (sticky `#persona-header` line + Ctrl+4 Persona TabPane; live updates on `AffectUpdate(status="current")`; on-mount hydration via the GET endpoint).
+- `[2026-05-26]` **Worldtree #201 / v0.29.0 integration (v0.14.0).** New SSE event `awaiting_llm_first_token` heartbeat (default 5s interval) during the BuildingPrompt→CallingLLM gap. Top-level event, NOT a worker_phase extension (preserves INV-053 three-field stability). `AwaitingLlmFirstToken` dataclass + parse; TUI live transcript indicator ("awaiting first token · Ns") mounted on first heartbeat, updated in place, removed when the gap closes; turn-summary line gains `heartbeats=N`.
+- `[2026-05-26]` **v0.14.1: CLI presenter forgot to update when wire-layer events were added.** AffectUpdate (v0.11.0) and AwaitingLlmFirstToken (v0.14.0) were added to the sse_client Event union and the TUI presenter, but `cli.py`'s `CliPresenterState.render` has its own isinstance check that wasn't widened. `ratatoskr --send` crashed AssertionError on any v0.28.0+/v0.29.0+ server. Patch shipped + a posture lesson: **always update BOTH presenters in lockstep when adding a wire-layer event** (the two presenters currently duplicate the isinstance tuple; refactor to a shared constant if a third wire-event lands).
+- `[2026-05-26]` **v0.14.2: RichLog min_width=78 silently overrides wrap=True.** Right-column panes (1fr against left's 2fr) are narrower than 78 cells at typical terminal widths; the renderer forces content to 78 wide then horizontal-scrolls. Fix: `min_width=0` on all four right-column RichLog instances.
+- `[2026-05-27]` **Issue #16 web companion shipped — v0.15.0.** Browser-based debug surface sibling to the TUI, reusing all wire-layer modules unchanged. New `ratatoskr.web` (Starlette app + lazy-import entrypoint + single-page vanilla HTML/CSS/JS UI), new console script `ratatoskr-web`, optional-deps group `[web]`. Nine HTTP endpoints; five-pane parity over the same SSE wire. Browser-native EventSource (GET stream + separate POST submit) — load-bearing Hulda correction from Heid panel; EventSource is GET-only. In-memory turn registry; browser-disconnect → upstream cancel; lifespan-shutdown drain with 5s budget. HTML-escaped transcript; upstream API key stays server-side. Default bind `0.0.0.0:8765` (LAN-trust model — operator direction; no auth, no TLS, no CORS).
+- `[2026-05-27]` **Heid panel review on web-companion scope v1 (pre-implementation).** Caught the EventSource POST/GET error + 7 other load-bearing items BEFORE we cut code. Confirms a pattern: **for non-trivial scope with non-obvious wire-protocol details, run a Heid panel BEFORE implementation, not just after.** Cost ~5min latency; saved a mid-implementation rewrite.
+- `[2026-05-27]` **Mid-session `system_prompt` mutation: REJECTED across the industry.** Operator-requested feature → Heid R13 panel (brokkr-claude + Eitri-Codex + Dvalin-Grok, strong convergence) ran a SOTA survey: NO surveyed mature system ships live PATCH-on-active-session for the system prompt (OpenAI Assistants/Responses, Anthropic Messages, Vertex AI, MCP, LangChain, LlamaIndex, Ollama, vLLM). The omission IS the answer; 12 additional threat vectors beyond ratatoskr's initial 7 surfaced (TOCTOU broader than BuildingPrompt window; KV/prefix cache contamination; supply-chain; Memory Control Flow Attacks >90% ASR on tested LangChain/LangGraph). Recommended alternative: client-side fork pattern (PATCH agent → mint new session → replay context). **Operator declined for ratatoskr** — debug TUI is wrong consumer; fork ergonomic belongs in a future production conversational shell. Thread closed cleanly (althing thread `01KSKD1GA3XBWR9RHGZCF9FE3Y`).
+- `[2026-05-27]` **Artemis (Gemma4) reasoning-token gap was upstream, not ours.** Wire trace from ratatoskr showed zero `thinking` events for `artemis-31b-v1i`; infra-ops confirmed llama-swap emits 77 `reasoning_content` deltas at the OpenAI-compat layer (`--reasoning-format deepseek`). Gap was in Worldtree's `GemmaProvider`. Worldtree-dev shipped v0.29.13 (commit `4262430`) fixing two stacked bugs: (1) base `OpenAICompatProvider._extract_thinking_from_delta` returned `None` unconditionally so any model falling through to the generic class dropped reasoning; (2) catalog `family` lookup was dead code (read wrong YAML subsection). Confirmed in ratatoskr via re-smoke against Sindra. **Diagnostic pattern: when a wire-layer feature appears missing, get infra-ops to probe upstream-of-the-SSE-publisher first; ratatoskr's wire trace says what reaches us, infra-ops's probe says what reaches Worldtree.**
+- `[2026-05-27]` **v0.15.1 (sessions): `get_persona_state` unwraps FastAPI `detail`-envelope.** Live smoke surfaced that real Worldtree returns persona-state errors as `{"detail": {"error_code": "..."}}` (FastAPI default), not flat. v0.12.0 tests mocked flat shape so the bug was invisible. **Lesson: test-side mock envelopes must match the REAL wire shape; live smoke is load-bearing for envelope-shape verification, not just happy paths.**
+- `[2026-05-28]` **v0.16.0 web Heid code-review pass 1: load-bearing turn_id fix.** Cancel paths used browser-local `_TURN_COUNTER` ids (1, 2, 3…) instead of upstream Worldtree turn_id (e.g. 799) captured from the first SSE event. The `disconnect_triggers_cancel` test gap was the load-bearing miss. Also: server-configured `RATATOSKR_END_USER_ID` (browser can no longer impersonate partition); narrowed missing-extras `ImportError` catch (real first-party bugs propagate as tracebacks instead of masking as exit-12); per-turn lifespan-shutdown logging. Contract amended with a v0.16.0 block + INV-005/006 updated + 4 FN sketches corrected.
+- `[2026-05-28]` **v0.16.1 web Heid code-review pass 2: minor tightening.** Stream-layer vocab coverage extended to all 11 Event types (AffectUpdate added to the vocab stream; dedicated `error_terminal_event` + `cancelled_terminal_event` tests since terminal events are mutually exclusive with done). Disconnect-cancel catch narrowed to swallow only `CancelAlreadyCompleted`/`CancelTurnNotFound` (the cooperative race); log unexpected `CancelFailed`/transport errors as structured stderr. **Heid review loop converged**: pass 1 = 7 findings (1 load-bearing); pass 2 = 2 minor (Gróa: zero findings, Hulda: 2). Pattern confirmed: diminishing returns within 2-3 passes; pass 3 would have been empty.
+- `[2026-05-28]` **Sindra Tier 3 agent: FORM ASSUMPTION gate + new physical-form description.** Persistent agent state changes via `python -m ratatoskr.tier3 patch`: (1) model migrated from `qwen3.6-35-a3b-heretic` to `artemis-31b-v1i`; (2) added FORM ASSUMPTION section — when instructed to become another character she IS that character (identity/environment/psychology/parameters), believes the environment as fact, no Sindra/holo-deck/parameter references, sticky until explicit revert; (3) replaced the abstract "classically beautiful" default-form sketch with a specific anti-artifice physical description (5'8", golden-copper skin, asymmetric features, oversize dark-green knit, bare feet). System prompt file is at `/tmp/personal-worldtree-sindra_system_prompt.md` (transient; not committed to repo). (Superseded 2026-06-17: sindra DELETE+redefined to `thoughtful-character` role on v0.35.16.)
+- `[2026-05-29]` **v0.17.0 frontend redesign — aurora telemetry instrument.** `/frontend-design` pass on the web companion: all-monospace technical-instrument aesthetic with the Australis dark palette + aurora-borealis accent band. Top command bar with live connection dot (idle/streaming/error states), inline persona summary with P/A/D micro-bars, animated awaiting-token, terminal-event status chips. **Live Markdown rendering in transcript + thinking panes** via a hand-rolled `markdownSafe()` (escape-first, whitelist subset of headings/bold/italic/inline-code/fenced/lists/quote/links; link-scheme whitelist; XSS-verified under a node harness). Thinking pane now has per-turn labeled dividers + a fresh MD-rendered block per turn. **Tools / Debug / Persona panes stay literal monospace** by deliberate choice — they carry structured audit lines + JSON, where MD would corrupt readability (underscores in tool names, JSON braces). Single-file vanilla HTML/CSS/JS, no build, no CDN, no node_modules.
+- `[2026-05-29]` **Codex-first discipline pilot — Ratatoskr selected.** brokkr-smithy-dev pushed `AGENTS.md` (commit `bbeaa23`) and declared the `ratatoskr-codex` handle per `brokkr-smithy/docs/codex-first-discipline.md` v0.1 (brokkr-smithy commit `5dd061c`, tag `v0.5.3`). Per-dispatch opt-in model: default Sleipnir Claude-implementer path remains available; Codex used only when operator routes via `/codex-dispatch <N>`. Bootstrap handshake when operator spins up a codex session: codex sends `codex-online` → ratatoskr-dev replies with active branches + WIP state. Galdrabok was rejected as pilot (Codex authoring Claude skills is a category error); Skaldsong was the other candidate. (Still dormant as of 2026-06-18 — no codex session spun up.)

+
+The 2026-05-20 → 2026-05-28 cluster: original-build-era foot-guns. Archived 2026-06-18.
+
+- `[2026-05-20]` **rich + prompt_toolkit framework choice.** Volva flagged that §1 and §5 pulled in opposite directions: a real side-panel observability surface would silently become a widget framework reimplementation. Operator's debug-observability reframe sealed the flip to Textual. Don't re-attempt rich+pt unless the scope shrinks to transcript-first REPL.
+- `[2026-05-20]` **In-tree at Worldtree/tools/ratatoskr/.** Earlier draft committed to in-tree-with-import-direction-smoke-test. Rejected at operator-routing — separate dev team forces separate repo.
+- `[2026-05-20]` **New `/persona/log` SSE endpoint on Worldtree.** Considered as alternative to file-tailing `persona.log`. Rejected — contract amendment + Vor round + AFK dispatch loop is weeks for a debug feature file-tail handles in a day. Trigger follow-up if a Worldtree-on-server / TUI-on-laptop debug case appears.
+- `[2026-05-20]` **Cross-process Last-Event-ID resume.** Considered — would require persisting per-session Last-Event-ID. Deferred to v2; v1 ships "reconnect, not resume-across-process."
+- `[2026-05-21]` **RichLog widget with `markup=True`.** Default impulse, but Rich interprets `[xxx]` spans as style markup and silently strips them. Every labeled stderr-style line — `[cancel_failed]`, `[done]`, `[error]`, `[busy]`, `[worker_phase]` — would render as just the content after the bracketed label. Fix: `markup=False`. Don't flip back without renaming every labeled-line format away from `[bracket]` notation.
+- `[2026-05-21]` **Querying `self.query_one("#transcript", RichLog)` from inside a Textual `run_worker` coroutine.** Initially failed with `NoMatches`. Reactive fix was widening worker signature to take `log` as parameter — Volva flagged as contract drift; reverted. Real fix was test-side: `await pilot.pause()` between `inp.action_submit()` and the polling loop so the handler finishes dispatching. Don't widen worker signatures to dodge test timing.
+- `[2026-05-21]` **TUI session-identity rendering via `self.sub_title` + `self.hint` plain attributes.** Stored state but never rendered to a visible widget. Tests asserted attributes (passed); Volva code-review flagged the gap. Fix: dedicated `Static(id="identity")` + `Static(id="hint")` widgets in compose; `_set_hint()` helper mirrors state → widget. **Calibration evidence for the "TDD catches state, code-review catches whether the user can see it" pattern.**
+- `[2026-05-23]` **Using the cross-model review agent's name directly in composed prose.** The peer review agent's name (the althing handle starting with "V-o-l-v-a") is one letter from a body-part term. Anthropic's content classifier does fuzzy matching and intermittently blocks responses mid-stream when the name appears in composed prose sentences. Mitigation: use role descriptions ("the cross-model reviewer," "the paraphrase peer") in prose rather than the name; quote content via tool output.
+- `[2026-05-22]` **`json.loads(sse.data)` unguarded against empty data.** `_iter_events` unconditionally called `json.loads` on every dispatched `ServerSentEvent`. When `httpx_sse` surfaced a frame with `id:` present but `data:` empty, `json.loads('')` raised `JSONDecodeError` → app crash. Fix: `if sse.data == '': continue` BEFORE `_parse_sse_id`. Don't reintroduce unconditional `json.loads(sse.data)`.
+- `[2026-05-23]` **Diagnostic shorthand: "2-events-then-silence" = Worldtree-side LLM-call wedge, not ratatoskr.** If a mimir `--send` smoke shows exactly two stderr events — `. create_session: ...` followed by `. worker_phase: phase=BuildingPrompt ...` — and then nothing for >60s, the root cause is upstream of ratatoskr. Worldtree's `service.py:2560` gates the `CallingLLM` event on the engine yielding its first LLM-provider chunk; if that connection is wedged at TCP level, the `async for` never iterates. Worldtree's 300s `_start_stall_timer` cancel-check is INSIDE the engine-event loop and so bypassed. **Don't bisect ratatoskr code when this shape appears** — diagnose the LLM-provider state at Worldtree's host. Restarting the Worldtree service clears wedged llama-swap connections. 10.250.50.152 hosts 3 instances (`:8080`/`:8081`/`:8082`) each with own DB + key namespace; our key is valid only on `:8081`.
+- `[2026-05-23]` **Phantom "per-Tier-1-agent scope add" pattern.** Issue #5's lofn 422 was initially mis-diagnosed as needing `agents.call:lofn` added. Routed to infra-ops via althing per credential-brokerage rule; infra-ops discovered no public scope-mutation endpoint, brokered to worldtree-dev. Worldtree-dev clarified: **Tier 1 foundational agents** are covered by a blanket `agent.call:*` (singular) baseline. There is no per-agent grant for Tier 1. **Tier 3 consumer-defined agents** use the plural `agents.call:<owner>:<agent>` shape registered via `POST /agents/define`. The notations differ by one letter. **The actual lofn fix was issue #5's `--end-user-id` flag** — always a request-body validation, not an auth-scope gate. Don't ping infra-ops for "per-Tier-1-agent scope adds."
+- `[2026-05-24]` **v0.8.x double-print: streamed Text + post-Done Markdown re-render.** Initial v0.6.0 design wrote each Text delta inline (with `· ` prefix) then re-rendered the full response as a Markdown Renderable on Done. Visually the response appeared twice. v0.8.2 dropped the post-Done Markdown body (interim regression). v0.9.0 fixed it properly with live Markdown rendering during stream (single Static widget holding a Markdown Renderable, updated in place). Don't reintroduce post-Done re-render unless you also remove the live-Markdown widget.
+- `[2026-05-26]` **Textual `RichLog(wrap=True)` insufficient on narrow widgets.** The default `min_width=78` overrides wrap on shrink — `max(renderable_width, min_width)` forces 78-cell rendering then horizontal-scrolls. Always set `min_width=0` on RichLog instances in a narrow column. Re-check on any future RichLog construction.
+- `[2026-05-26]` **Wire-layer event added without updating BOTH presenters.** v0.11.0 (AffectUpdate) and v0.14.0 (AwaitingLlmFirstToken) widened the sse_client Event union + TUI presenter's isinstance tuple, but missed cli.py's identical-shape tuple. `--send` mode then crashed on any persona-enabled or slow-first-token turn. Patch fix in v0.14.1. **Rule: when adding a wire-layer event, grep for `isinstance(event, (` across the repo** — currently TUI and CLI presenters both carry duplicate hardcoded tuples. Refactor to a shared `_EVENT_VOCAB` constant if a third wire-event lands.
+- `[2026-05-27]` **EventSource is GET-only — scope v1's POST stream endpoint would have broken.** Web companion's first scope had `POST /api/turns/{sid}/stream` for the SSE proxy. Browser-native `EventSource` only supports GET. Hulda caught it in Heid panel review BEFORE we cut code. Pattern: `POST /api/turns/{sid}` registers the turn locally + returns turn_id; `GET /api/turns/{sid}/stream?turn_id=N` streams via EventSource; cancel is a separate POST. **Load-bearing reason to Heid-panel non-trivial wire-protocol designs BEFORE implementation, not just after.**
+- `[2026-05-27]` **`get_persona_state` mocked flat error envelope; real Worldtree wraps in `detail`.** v0.12.0 tests used `{"error_code": "auth_scope_denied"}` but real wire (FastAPI default) returns `{"detail": {"error_code": "auth_scope_denied", "message": "…"}}`. The parser only checked top-level so the typed exception was never raised; calls fell through to `SessionApiFailed(403)`, which the web persona endpoint surfaced as HTTP 500. v0.15.1 patches both shapes. **Lesson: test-side mock envelopes must match the REAL wire shape; live smoke is load-bearing for envelope-shape verification, not just happy paths.**
+- `[2026-05-27]` **Mid-session `system_prompt` mutation: universal omission across surveyed mature systems.** brokkr-smithy R13 panel (3-arm, strong convergence) confirmed: no surveyed system ships live PATCH-on-active-session (OpenAI Assistants/Responses, Anthropic Messages, Vertex AI, MCP, LangChain, LlamaIndex, Ollama, vLLM). The omission IS the answer. 12 additional threat vectors beyond ratatoskr's initial 7. **Don't re-propose this for ratatoskr;** if a future production conversational shell wants iterative-prompt-tuning ergonomics, the consensus shape is fork-via-client (PATCH agent → new session → replay context).
+- `[2026-05-28]` **Browser-local turn_id used for upstream cancel URL — old cancel tests ENCODED the bug.** Web companion v0.15.x cancel paths posted to `/sessions/{sid}/turns/{LOCAL_ID}/cancel`. Tests mocked the local-id URL so they encoded the bug rather than detecting it. Hulda caught it in Heid pass 1. Fix in v0.16.0: capture upstream_turn_id from the first SSE event's `sse_id.turn_id`; all cancel paths use it; cancel before first event is `{"cancelled": false, "reason": "not_started"}`. **Rule: when designing cancel/match paths against an external service, test fixtures must mock what would actually be hit upstream — mocking your own derived id encodes the bug instead of catching it.**

Drove a consumer fix: `--set-persona-pad` now sends the canonical `{pad:{pleasure,arousal,dominance}}` named dict (was `{pad:[list]}`) — #317, `v0.19.7`. Foot-guns encoded: persona.ocean single-letter `{O,C,E,A,N}` on `/agents/define` (spelled-out → 422, the #348 mismatch) vs spelled-out on `POST /characters`; memory `{embedder_version, tier3_dreaming}`, stm_* deprecated, allows_world_scope removed→422; only `valence` still 422s. `pin:`-only for the markdown; the `v0.19.7` bump rode the persona_state code fix. |

+
+# First-message presets — authored openings on session-create (#347)
+
+## Context
+
+`ratatoskr.first_message` holds per-agent authored-opening presets and seeds them
+onto new sessions via the #347 authored-history-write primitive. It is the
+durable form of "give an agent a first message": instead of a system-prompt
+`Startup:` instruction (a workaround for the pre-#347 world where the assistant
+could not author turn-0), the opening lives as a real seeded assistant turn-0.
+
+Consumed at both session-create sites — `ratatoskr.cli._amain` (the `--new` path)
+and `ratatoskr.web.server._create_session_endpoint` (POST /api/sessions) — so
+every new session for a preset agent opens in-character regardless of surface.
+
+## Data flow
+
+**In:** a live `httpx.AsyncClient` (caller-owned, base_url + bearer set), a fresh
+`session_id`, and the bound `agent_id`.
+
+**Out:** on a preset agent, one `POST /sessions/{session_id}/history` (author=assistant,
+the preset text, per-content idempotency key). Returns the seeded content on
+success, else `None`.
+
+**Side effects:** at most one outbound authored-history write; never raises to the
+caller (best-effort).
+
+## Invariants
+
+- **INV-001 [hard]**: `seed_preset_first_message` NEVER raises (the sole exception is
+  `asyncio.CancelledError`, which propagates — cancellation is not a seed failure) and
+  NEVER blocks session creation. It soft-guards its inputs (a bad arg returns `None`,
+  not `AssertionError`), bounds the write with `asyncio.wait_for(_SEED_TIMEOUT_S)` so a
+  stalled `/history` can't hang the create path, and swallows EVERY other exception (the
+  hide-404, `SessionApiFailed`, `httpx.HTTPError`, `TimeoutError`, and any unexpected
+  error) → `None`. The `broad-except` is deliberate: this helper is wired INTO three
+  session-create paths, so any escape would abort a create that already succeeded.
+- **INV-002 [hard]**: a no-preset agent issues ZERO HTTP (early return before any
+  request).
+- **INV-003 [hard]**: the seed body is the preset text verbatim, author="assistant",
+  with a per-content idempotency key (`"ratatoskr-preset-" + sha256(text)[:12]`), so
+  a repeat seed of the same session+preset is an idempotent 200 replay, never a
+  duplicate turn.
+- **INV-004 [hard]**: no `core.*` / `worldtree.*` imports (reference-consumer
+  boundary; verified by `tests/test_no_worldtree_imports.py`, which rglobs every
+  `.py` under `src/ratatoskr/` — this module included, so no per-module import
+  test is needed here).
+
+## Out of scope
+
+- **Multi-turn / scripted openers.** v1 seeds exactly one assistant turn-0. A
+  multi-message opening scene is a future concern.
+- **Runtime/remote preset config.** The registry is an in-module dict; no file/DB/env
+  loading. Add that only when a second consumer needs operator-editable presets.
+- **Non-assistant authors.** v1 is author=assistant only (matches #347 v1); a
+  user/system opener is deferred with the #347 engine surface.
+- **TUI-only surfaces.** Both real session-create paths (CLI + web) are wired; the
+  bare-TUI picker resumes existing sessions (no create), so it needs no seed.

+## Amendment 2026-06-30 — shared resume orchestration (v1 coverage-audit, slice b1)
+
+The original contract specs resume as **caller-owned** (§Resume semantics: "the
+caller MAY invoke `reconnect_turn`"). The v1 coverage-audit found `reconnect_turn`
+had **no caller** — every presenter (cli/tui/web) let a mid-stream drop propagate
+instead of resuming, so the "reference SSE-resume implementation" (design-brief
+§3/§8d) was unreachable. Per design-brief §8b ("share the consumer, branch the
+presenter") the resume loop is a **single shared orchestration surface**, not
+duplicated per presenter. This adds `stream_turn_resilient` as that surface;
+presenters call it instead of `stream_turn` when they want transparent reconnect.
+`stream_turn` and `reconnect_turn` are unchanged (still the primitives); this is
+purely additive.

+BRIEF: The shared resume-orchestration wrapper over stream_turn + reconnect_turn. Yields a SINGLE continuous typed Event stream; on SseConnectionDropped (mid-stream drop OR clean EOF before terminal), transparently resumes via reconnect_turn from the last-seen sse_id, up to max_reconnects times, until a terminal Done/Error/Cancelled arrives. The one surface all presenters consume for resilient streaming (design-brief §8b). Cross-process resume stays deferred to v2 (§8d): last-seen lives only in this generator's frame.

D1 = build_combined_provider_app fronting BOTH planes on :8392, advertising both caps by store PRESENCE, mounting the SAME affect read route (INV-007), with the op-feed deriving plane PER request path (plane='combined'); per-plane failure isolation is bifrost's (per-route call-time dispatch isolation in one ASGI process). Direct in-session TDD (the #17 pattern). The panel framing-consult (Heid, 3 arms) pressure-tested this design; its triaged findings are folded in as INV/POST clauses below."

+# Issue #18 (Deliverable 2) — PAD read-endpoint → persona pane renders OUR store
+
+## Context
+
+Ratatoskr binds a Tier-3 session to its own affect provider (:8390) and Worldtree
+persists the agent's PAD/valence there (live-proven: vuong session pleasure +0.146,
+familiarity 0.18→0.59 over 8 turns). But the web pane shows "telemetry isn't exposed":
+it reads Worldtree `persona_state` (`loadPersona`, index.html:707), which 404s for every
+Tier-3 colon-id agent (ADR-0009, Tier-1-only), AND a Tier-3 turn emits zero
+`affect_update` SSE. Both Worldtree-side persona sources are dead for consumer agents.
+The pane was never wired to render PAD from OUR store — Deliverable 2 closes that.
+
+**Scope is the PAD-display half ONLY.** Deliverable 1 (the composite :8392 endpoint that
+lets one session bind both planes) is bifrost-blocked: bifrost-dev has confirmed a public
+`bifrost.consumer.build_combined_app` (clean additive minor, ~v0.9.0, design locked) and is
+standing by on the open Worldtree-dispatch question (FR-1). This contract is amended to add
+Deliverable 1 once that lands. Deliverable 2 has zero bifrost or Worldtree dependency — it
+reads our own `affect.db` — so it ships now, independently.

+| web proxy | (passthrough) | provider status | provider 404/400 surfaced to the browser verbatim |
+
+## Invariants
+
+- **INV-001 (honest shape, no fabrication).** The pane renders ONLY fields the
+  affect.emit snapshot actually carries — `pad{pleasure,arousal,dominance}`, per-entity
+  `valence[]` (familiarity/regard/interaction_count), `emitted_at`. It MUST NOT
+  synthesize Tier-1 `persona_state` fields (`dominant_emotion`, `baseline_pad`,
+  `mood_drift`, `emotions_active`) — those are platform concepts Tier-3 structurally
+  lacks (ADR-0009); a fabricated empty `mood_drift` reads as a bug, not an absence.
+- **INV-002 (end_user_id is server-supplied, never browser).** The web proxy reads
+  `end_user_id` from `app.state.end_user_id` (RATATOSKR_END_USER_ID); it MUST NOT accept
+  one from the browser body/query. Mirrors #17 INV-006 — a client cannot read an
+  arbitrary end-user's affect partition.
+- **INV-003 (empty/missing is fail-visible).** No emit yet for (agent, user) → an
+  EXPLICIT no-data state (provider 404 `no_affect_snapshot`; pane shows "no affect
+  emitted yet for this agent / user"). NEVER a zeroed `pad:{0,0,0}` that looks like real
+  PAD. A missing/unset `RATATOSKR_END_USER_ID` is a visible config error, not a silent
+  empty result.
+- **INV-004 (op-feed + scope semantics untouched).** The read route is non-bifrost and
+  sits OUTSIDE `opfeed._BIFROST_PATHS`, so the op-feed passes it through and emits no
+  OpEvent for it. Deliverable 2 changes neither op-feed behavior nor store scope/affect
+  semantics; the store stays conduit-opaque (it returns the stored blob verbatim).
+- **INV-005 (label honesty).** When the pane renders affect-store data it is labelled
+  "affect" (e.g. "affect snapshot"), NOT "persona" — the data is affect, not Worldtree
+  persona_state, and the label must not imply otherwise.
+- **INV-006 (SQLite busy_timeout).** Every affect-store connection sets
+  `busy_timeout >= 5000ms`. WAL permits one writer + many readers but the default
+  busy_timeout is 0 (a contended write returns SQLITE_BUSY immediately). This is prep
+  for the future composite/standalone two-process topology; harmless single-process.
+- **INV-007 (read route on the store owner; pane decoupled via configured URL).** The
+  read route is mounted by whatever app owns the affect store; the pane proxies to
+  `RATATOSKR_AFFECT_READ_URL`, so it renders regardless of which endpoint a session is
+  bound to. The deferred composite (Deliverable 1) will mount the SAME read route over
+  the SAME `affect.db` — one shared helper, not a composite-only feature.
+- **INV-008 (colon-id round-trip).** A Tier-3 `agent_id` containing `:`
+  (`ratatoskr:sindra`) round-trips browser → web (`encodeURIComponent`) → provider (web
+  re-encodes via `quote(agent_id, safe='')` into the provider path) → `store.get`. Both
+  hops are asserted end-to-end with a colon-id (Heid panel FM-7).
+
+## Data flow
+
+PANE LOAD (poll, no SSE): on session-start and after each turn-end, the pane calls
+`loadPersona(agentId)`. For a colon-id (Tier-3) agent it dispatches to `loadAffect` →
+`GET /api/affect/{agent_id}` → the web server supplies `end_user_id` server-side →
+proxies to `GET {affect_read_url}/affect/state/{quote(agent_id)}?end_user_id=…` → the
+provider reads `store.get(agent_id, end_user_id)` → snapshot JSON (200) or
+`no_affect_snapshot` (404) → `renderAffectPane` or the explicit empty-state. For a
+non-colon (Tier-1) agent, the existing `persona_state` path is unchanged.

+
+## Acceptance
+
+Unit (respx + in-process store):
+1. provider read route: seeded store → 200 with the exact snapshot; unseeded (agent,user) → 404 `no_affect_snapshot`; missing `end_user_id` → 400.
+2. provider app: `/bifrost/handshake` + `/bifrost/affect-call` still reachable after the read route is composed in (INV-004 / POST-002).
+3. web proxy: supplies server `end_user_id` (browser-supplied one is ignored); colon-id `ratatoskr:sindra` round-trips into the provider path (INV-008); provider-unreachable → 502; unconfigured → 400.
+4. op-feed: a request to `/affect/state/...` produces NO OpEvent (INV-004).
+5. busy_timeout: `open_affect_store` connection reports `busy_timeout == 5000` (INV-006).
+
+Live-smoke (load-bearing, manual — the repo's posture): with the affect provider up and a
+prior emit for `ratatoskr:sindra` / the configured end_user, open the web pane on that agent
+→ the pane renders live PAD + valence + `emitted_at` from OUR store (no "telemetry isn't
+exposed"); on a fresh (agent,user) with no emit → the explicit empty-state, not a zeroed PAD.
+
+## Deliverable 1 — composite endpoint (`build_combined_app`)
+
+### Context
+
+One bound Worldtree session that both remembers (memory.*) AND shows live PAD
+(affect.*). bifrost 0.10.0 ships `bifrost.consumer.build_combined_app(memory_store,
+affect_store, verifier, registration, maintenance_store=None) -> ASGIApp`: ONE app
+exposing handshake + `/bifrost/memory-call` + `/bifrost/affect-call` (no legacy
+`/bifrost/tool-call`), advertising BOTH caps by store PRESENCE. FR-1 is resolved:
+Worldtree runs one `BifrostClient` per session off a single `_endpoint_url`, parses
+`capabilities_granted` independently into memory+affect sets, and attaches each store
+iff its cap was granted — so a single `:8392` endpoint advertising both caps drives
+both planes with ZERO Worldtree change. D1 is bifrost-only on our side: compose the
+combined app + mount our existing affect read route + derive the op-feed plane per
+path. It is ADDITIVE — the standalone `:8390`/`:8391` apps are unchanged.
+
+### Public surface (D1)

+```
+
+### Invariants (D1)
+
+- **INV-009 (both stores REQUIRED).** `build_combined_provider_app` requires a real
+  memory_store AND affect_store; bifrost's `build_combined_app` raises `ValueError`
+  if either is None (single-plane consumers use `build_affect_app`/`build_memory_app`).
+  We pass our real SQLite-backed stores; no in-memory default.
+- **INV-010 (advertise BOTH caps by store PRESENCE).** The combined handshake grants
+  `memory` and `affect` by the presence of each advertising store (memory needs
+  `describe_store`; affect needs `affect_supported` + `emit` + `fetch`, strong-or-absent
+  — see the affect-provider contract INV-010) — NOT a runtime health probe. The affect
+  cap therefore depends on Deliverable-prerequisite `affect.fetch` already shipped.
+- **INV-011 (SAME affect read route, shared helper).** The composite mounts the
+  identical `GET /affect/state/{agent_id}` route over the SAME affect store, via the
+  shared `add_affect_read_route` helper — NOT a composite-only reimplementation
+  (fulfils the D2 INV-007 promise). The pane reads it through `RATATOSKR_AFFECT_READ_URL`
+  regardless of whether the bound endpoint is `:8390` or `:8392`.
+- **INV-012 (op-feed plane derived PER request path).** On the composite, the op-feed
+  cannot use a fixed `plane` — both planes share one app. With `plane='combined'` it
+  derives the OpEvent plane from `scope['path']`: `/bifrost/memory-call`→`memory`,
+  `/bifrost/affect-call`→`affect`, `/bifrost/handshake`→`combined`. The per-verb
+  summary logic already keys on path, so memory/affect summaries stay correct; this is
+  purely the plane STAMP. The non-bifrost read route stays outside `_BIFROST_PATHS`
+  (no OpEvent), unchanged.
+- **INV-013 (per-plane failure isolation is bifrost's, honest).** Failure isolation is
+  per-route CALL-TIME dispatch isolation within ONE shared ASGI process — a memory-call
+  failure does not corrupt an affect-call and vice-versa. Bind-time + process-crash are
+  SHARED domains (one process), not independent services; the contract does not claim
+  otherwise. We add no isolation layer of our own.
+- **INV-014 (additive — standalones unchanged).** `:8392` is a NEW endpoint alongside
+  `:8390`/`:8391`; `build_affect_provider_app`/`build_memory_provider_app` and their
+  serve entrypoints are untouched. The composite + a standalone may open the SAME
+  `affect.db` (two processes) — hence the affect store's `busy_timeout` (D2 INV-006).

+
+### Acceptance (D1)
+
+Unit (in-process, dispatch JWTs via `bifrost.core.dispatch_jwt.mint_dispatch_jwt` — the #17 posture):
+1. `build_combined_provider_app` → app with all four routes; handshake grants both caps.
+2. a memory `search` + an affect `emit` both dispatch through the one app (INV-013).
+3. the affect read route works on the composite for a colon-id (INV-011).
+4. `affect_store=None` → ValueError (INV-009).
+5. op-feed `plane='combined'`: a memory-call stamps `plane='memory'`, an affect-call stamps `plane='affect'`, a handshake stamps `plane='combined'` (INV-012); the read route emits NO OpEvent.
+
+Live-smoke (manual, the repo's posture): start `:8392`, bind a Tier-3 session to it, drive a turn → the op-feed shows BOTH a memory op and an affect emit at the bound session_id; the web pane (pointed at `:8392` via `RATATOSKR_AFFECT_READ_URL`) renders live PAD. Then ping bifrost-dev that the composite landed.
+
+## Out of scope / DEFERRED (anti-creep)
+
+- **Deliverable 1 — composite :8392 endpoint** — RESOLVED: now in scope, see
+  § *Deliverable 1* above (bifrost 0.10.0 `build_combined_app` shipped + FR-1 resolved).
+- WT #289 mediated affect-read (`affect.fetch` over bifrost) — we own the store, read it
+  directly; no Worldtree dependency.
+- Production hardening (TLS/RS256 on the read route; auth on /affect/state) — internal-LAN
+  trust model, consistent with the rest of ratatoskr.web.
+- Real-time push of PAD into the pane — Tier-3 emits no affect SSE; v1 polls. A push channel
+  would need a Worldtree-side affect SSE, out of scope.

+## Amendment 2026-07-06 — authored-history write (#347, v1 coverage-audit re-open)
+
+Worldtree shipped #347 (authored-history-write) as OpenAPI 2.3.0: a new
+`POST /sessions/{session_id}/history` primitive that writes ONE model-visible
+turn into a session's ledger AS the bound agent, WITHOUT a generation and
+WITHOUT lived-turn side effects (the SillyTavern "first message"). The re-vendor
+(2.2.0→2.3.0, pin `879cefe`) re-opened the v1 coverage-audit with this one new
+in-scope REST path-group; this amendment closes it on the consumer side and also
+un-defers `GET /sessions/{id}/messages` (previously §Out of scope) as the seed's
+read-back.
+
+**Hide-existence (server INV-347-1) — the load-bearing consumer contract.** The
+`session.history.write` grant is checked FIRST — an ungranted caller (or a
+non-owner, or an unknown session) gets a 404 **byte-identical** to a genuine
+`session_not_found`, never a 403/409/422 that would reveal the feature exists.
+The consumer MUST honor this: treat 404 as **feature-absent**, fall back (a
+production consumer to a model-generated greeting), and NEVER capability-probe to
+tell feature-absent from ungranted from session-absent. The wrapper encodes it by
+raising a DISTINCT `AuthoredHistoryUnavailable` on 404 (NOT `SessionApiFailed`),
+so a caller branches feature-absent without inspecting a status code.
+
+**Request body — v1-minimal, wire-pinned by the server.** The frozen OpenAPI 2.3.0
+exports an empty request schema, but the server pins `AuthoredWriteRequest`
+(`extra="forbid"`): `{author, content, idempotency_key, effects?,
+claimed_original_at?}`. v1: `author="assistant"` (only value), `content` (UTF-8,
+server-bounded at `authored_content_max_bytes`=8192), `idempotency_key` (REQUIRED,
+per-session dedup), `effects` omitted (== "none"; only value). Because
+`extra="forbid"`, the wrapper omits `effects`/`claimed_original_at` when None
+(never sends null). Success is 201 (fresh) OR 200 (idempotent replay,
+byte-identical body); both return the `AuthoredTurnResponse` `{author,
+content_chars, injected_at, phase, seq, session_id, turn_id}` verbatim (provenance
+is audit-only, NEVER on this body — INV-347-7).
+
+**Assistant-first provider constraint (deferred, inert for the probe).** A
+create-time first-message makes the assistant seq-0 (assistant-first history);
+Anthropic-family providers 400 the *next generation*, vLLM/openai_compat tolerate
+it. The `--seed-first-message` probe seeds but does NOT generate, so the
+constraint is inert for the probe — a real consumer that then generates must bind
+an assistant-first-tolerant provider.

+session picker (design-brief §4: "single-session-per-launch, with a startup
+picker invoked when more than one session exists ... plus flags `--session`/
+`--new` to skip it") was never built. Bare TUI mode (neither `--session` nor
+`--new`) was a hard usage error. This adds the picker as a pre-alt-screen
+resolution step in `_resolve_then_run`, mirroring the existing `AgentPickerApp`.
+
+**Locked design (design-brief §4):** the picker is **resume-only** (§4 negative
+clause "no in-app session creation — `--new` flag only"); shown only when **>1**
+session exists (exactly 1 auto-resumes; the launch intent is "resume the last
+session I was poking at"). `--agent` stays a `--new` companion (forbidden in bare
+mode). **bare + 0 sessions → error** `[no_sessions]` directing the operator to
+`--new` (honors the "no in-app creation" clause; the friendlier
+auto-fall-through-to-new alternative is deferred pending operator confirmation).
+
+### `_parse` validation relaxation (ratatoskr.cli._parse)
+
+- Bare TUI mode (`send is None` AND no `--session` AND no `--new`) is now VALID
+  → triggers the picker. (Previously `raise UsageError("pass exactly one of
+  --session or --new")` unconditionally.)
+- `--send` mode still requires exactly one of `--session`/`--new` (non-
+  interactive: no picker can open) → `UsageError("--send requires --session or
+  --new")`.
+- `--session` + `--new` stays mutually exclusive.
+- `--agent` in bare mode → `UsageError` (`--agent` belongs to `--new`).

+FN SessionPickerApp.__init__(self, sessions: list[SessionInfo]) -> None
+BRIEF: Textual App[str | None] startup session picker (mirrors AgentPickerApp, issue #8). Opens before RatatoskrApp when bare TUI mode resolves >1 session. `run_async()` returns the chosen session_id (str) or None on Esc/Ctrl-D/Ctrl-C dismissal. Architecturally separate from RatatoskrApp (list_sessions failures + dismissal land before any alt-screen — preserves #6 INV-001).
+PRE: [PRE-001 hard] sessions is non-empty -- assert sessions (caller resolves 0-session and 1-session cases BEFORE constructing the picker)
+POST: [POST-001 return_value] run_async() returns sessions[i].session_id for the highlighted row on `pick`, or None on dismiss -- assert result in {s.session_id for s in sessions} | {None}
+STEPS:
+  1. [setup, prescriptive] Store sessions; register the Australis theme (mirror AgentPickerApp).
+  2. [sequential, prescriptive] compose: Header + prompt Static + ListView of one ListItem per session (id-short + agent_id + last_active/name lines) + Footer.
+  3. [sequential, prescriptive] BINDINGS: enter→action_pick, escape/ctrl+d/ctrl+c→action_dismiss.
+  4. [branch, prescriptive] action_pick: read ListView.index; if None return (nothing highlighted); else exit(sessions[index].session_id). action_dismiss: exit(None).
+TESTS:
+  pick_returns_session_id [happy,tracer]: SessionPickerApp([s0, s1]); pilot highlights row 1 + press enter → run_async() returns s1.session_id.
+  dismiss_returns_none [happy]: press escape → run_async() returns None.
+  ctrl_d_dismisses [adversarial]: press ctrl+d → None.
+
+FN _resolve_then_run(args) — bare-mode extension (session picker)
+BRIEF: Before the existing new/resume branches, resolve bare TUI mode (not args.new AND args.session_id is None) via list_sessions + the picker. Sets a local `effective_new` and `resolved_session_id`; the existing branches then run unchanged on those locals.
+STEPS (inserted at the top of the `async with client` block):
+  1. [setup, prescriptive] SET effective_new = args.new; resolved_session_id = args.session_id.
+  2. [branch, prescriptive] IF (not args.new) AND (args.session_id is None):  # bare mode
+       a. CALL list_sessions(client) → page; ON SessionApiFailed → stderr `[session_api_failed]` + return 20; ON network error → `[network_error]` + return 21.
+       b. IF not page.items: stderr `[no_sessions] no sessions to resume; launch with --new --agent <id>` + return 14.
+       c. ELIF len(page.items) == 1: SET resolved_session_id = page.items[0].session_id.  # §4: picker only when >1
+       d. ELSE: SET resolved_session_id = await SessionPickerApp(page.items).run_async(); IF None → return 0 (Esc/Ctrl-D clean exit).
+  3. [sequential, prescriptive] Replace the two `if args.new` predicates with `if effective_new`; the resume `else` branch asserts + uses `resolved_session_id`.
+TESTS (in the `_resolve_then_run` block):
+  bare_zero_sessions_errors [error]: bare args; list_sessions → 0 items → stderr contains `[no_sessions]`; return 14; NO POST /sessions, NO picker.
+  bare_one_session_auto_resumes [scenario]: bare args; list_sessions → 1 item (sid="s-solo") → RatatoskrApp constructed with session_id="s-solo"; NO picker shown.
+  bare_multi_opens_picker [scenario,tracer]: bare args; list_sessions → 2 items; picker returns items[1].session_id → RatatoskrApp constructed with that session_id.
+  bare_picker_dismiss_exits_zero [scenario]: bare args; 2 items; picker returns None → return 0; RatatoskrApp NOT constructed.
+  bare_list_sessions_api_failure [error]: bare args; list_sessions raises SessionApiFailed(500) → stderr `[session_api_failed]`; return 20.

(2) BifrostState pane: GET /api/sessions/{id}/bifrost proxies admin-scoped get_session_bifrost; the admin key is SERVER-HELD (app.state.admin_key from RATATOSKR_ADMIN_API_KEY), never sent to the browser. (3) AdminEvents pane: GET /api/admin/events is an SSE proxy of stream_admin_events, session-filtered SERVER-side (heartbeats + other-session events dropped), re-emitted under a fixed 'admin_event' name so every dotted type renders with one browser listener. (4) PAD refresh: the persona/affect pane polls a bounded window instead of a single 2s shot that raced the post-turn-async affect.emit.

+# v0.19.2 — web debug-surface parity (BifrostState · AdminEvents · Tools · PAD-poll · reasoning)
+
+## Context
+
+The browser surface is now the operator's PRIMARY debug surface, and it lagged the
+TUI: the TUI gained Tools/BifrostState/AdminEvents panes (v0.18.9–.11) that were never
+ported to the web. This change closes that gap and adds two transcript affordances (a
+reliable PAD refresh + a reasoning indicator). The client wrappers already existed and
+are contracted elsewhere; this contract governs the WEB proxy routes + the SPA presenter
+paths, whose JS render code is not unit-tested — hence the cross-frontier code review.
+
+## Review focus (for the heid panel)
+
+1. **INV-004 escaping** in every new render path — the un-unit-tested surface; the exact
+   class of bug (`renderPersonaPane` fabricating a Tier-1 field) that only a cross-model
+   review caught on #18 D2.
+2. **INV-ADMIN-KEY** — confirm the admin key never reaches a response body or the browser.
+3. **AdminEvents SSE proxy** (`_admin_events_endpoint`) — generator/filter/lifecycle: fixed
+   event name, server-side filter, `stream_error` on failure, `aclose()` on every path,
+   `CancelledError` re-raise on disconnect.
+4. **PAD-poll** stop-condition — does `emitted_at` advancement + the `state.turnId` guard
+   correctly stop the poll without racing or leaking timers?
+5. **Reasoning indicator** lifecycle — shown on first `thinking`, removed on first `text`
+   or terminal, interval cleared (no leaked `setInterval`), name via `textContent`.

+##### Persona layer (Phase 2.1, #186)
+
+`persona` is **active** as of Phase 2.1. It carries the agent's OCEAN
+personality vector — the durable trait profile from which Worldtree
+derives the mood setpoint (`baseline_pad`) and the mood dynamics
+(gain + relaxation time-constants). Shape:
+
+```json
+"persona": {
+  "ocean": {                     // REQUIRED — exactly these 5 keys, no more, no fewer
+    "O":  0.4,                   // Openness           — float in [-1.0, 1.0]
+    "C":  0.6,                   // Conscientiousness
+    "E": -0.3,                   // Extraversion
+    "A":  0.2,                   // Agreeableness
+    "N":  0.5                    // Neuroticism
+  },
+  "behavioral_notes":  "...",    // optional, ≤ 4096 chars
+  "temperament_notes": "..."     // optional, ≤ 4096 chars
+}
+```
+
+**⚠ OCEAN key format — single-letter, uppercase.** The `/agents/define`
+persona validator requires the `ocean` map to contain **exactly** the five
+uppercase single-letter keys `O, C, E, A, N`. This is a deliberate,
+load-bearing contrast with the transient-character primitive
+(`POST /characters`), whose `ocean` block uses the **spelled-out**
+lowercase keys (`openness`, `conscientiousness`, …). Sending spelled-out
+keys to `/agents/define` returns 422 `persona_ocean_required` ("must
+contain exactly the 5 keys O, C, E, A, N").
+
+> **Fixed in v1.0.0b21 (#348).** Before that build a correctly
+> single-letter-keyed persona was accepted and stored, but resolved to a
+> **neutral** mood, because Worldtree's internal mood-derivation read the
+> spelled-out key form. On v1.0.0b21+ an API-declared persona correctly
+> drives the derived mood setpoint. If you observe neutral mood on a
+> persona-defined agent, confirm the deployment is ≥ v1.0.0b21.
+
+**Range.** Each value is a float in `[-1.0, 1.0]` **signed** — `0.0` is the
+population mean, NOT `[0.0, 1.0]`. Booleans are rejected. Out-of-range → 422
+`persona_ocean_out_of_range`. See [`docs/ocean-traits.md`](ocean-traits.md)
+for the SOTA-grounded 5-band behavioural mapping.
+
+Semantics:
+
+- **Per-agent identity trait** — identical for every end-user and session;
+  immutable post-define (`PATCH {"persona": …}` → 422 `field_not_mutable`).
+  To change the OCEAN profile, delete and re-define the agent.
+- **`extensions` is reserved** — the field exists but must be empty at v0.1;
+  a non-empty `extensions` returns 422 `layer_deferred`.
+- **Sets the mood SETPOINT, not the current mood.** The OCEAN vector fixes
+  `baseline_pad` (the PAD point the mood relaxes toward over time); the
+  *current* per-session mood point is seeded separately via
+  `POST /sessions/{id}/persona_state` (below).
+
+Validation 422 codes: `persona_ocean_required` (missing `ocean`, or keys
+≠ {O,C,E,A,N}), `persona_ocean_out_of_range` (a value outside [-1.0, 1.0], or
+a boolean), `persona_notes_too_large` (a note > 4096 chars), `layer_deferred`
+(non-empty `extensions`), `validation_failed` (unknown top-level field).
+
+##### `POST /sessions/{session_id}/persona_state` — seed the session mood point (Phase 2.1, #186/#189)
+
+Session-scoped mood seed. Sets the *current* PAD mood point for one
+session's bound agent — the starting emotional state, distinct from the
+OCEAN-derived setpoint the mood relaxes toward. Works on any
+persona-enabled session (Tier 1 or Tier 3); most useful for a Tier 3
+durable-agent session that wants to start a conversation from a specific
+mood.
+
+Request:
+
+```json
+{
+  "pad": {
+    "pleasure":  0.42,           // float in [-1.0, 1.0]
+    "arousal":   0.25,
+    "dominance": 0.33
+  }
+}
+```
+
+Response: **`204 No Content`** — no body, no audit event (a session-scoped
+runtime overlay, not a security-relevant event).
+
+Semantics:
+
+- **PAD-only** (#317 Option A). The body accepts exactly one key, `pad`,
+  which must carry all three of `pleasure` / `arousal` / `dominance`, each a
+  float in `[-1.0, 1.0]`. Any other top-level key → 422 `validation_failed`;
+  a missing or malformed `pad` → 422 `persona_seed_invalid`.
+- **Seeds the current mood POINT, not the setpoint.** The OCEAN persona
+  (above) fixes the setpoint the mood relaxes toward; this endpoint sets
+  where the mood *starts*. It does not alter the persona.
+- **Cross-owner sessions return 404** (existence-hiding — a session that
+  isn't yours is indistinguishable from one that doesn't exist).
+- **Pull-over-push precedence (#289).** Once a session's baseline has been
+  rehydrated from an `affect.fetch` (the authoritative cross-session
+  source), a later SET seed is silently ignored — the fetched baseline wins.
+
+There is **no** `POST /agents/{id}/persona_state` — mood is per-session, not
+a durable agent property. `GET /agents/{agent_id}/persona_state`
+short-circuits to 404 for Tier-3 colon-ids: Tier-3 mood is observable only
+over the Bifrost `affect.emit` egress (ADR-0009), never read back through
+the HTTP API.
+
+##### Memory layer (Phase 2.1, #197)
+
+`memory` is **active** as of Phase 2.1 but exposes a deliberately minimal
+surface — the short-term-memory (STM) tier was removed (#197), so the
+historically-present `stm_*` knobs are accept-and-ignore no-ops. Shape:
+
+```json
+"memory": {
+  "embedder_version": "<pinned>",   // optional; MUST equal the library-pinned version
+  "tier3_dreaming":   false         // optional bool, default false
+}
+```
+
+Semantics:
+
+- **`embedder_version`** — optional. If supplied it MUST equal the library's
+  currently-pinned embedder version; a mismatch → 422
+  `embedder_version_mismatch` (with `expected` / `received` in the detail).
+  Omit it to accept the pin. Fixed at define-time and library-pinned
+  thereafter.
+- **`tier3_dreaming`** — optional bool (default `false`); opt-in flag for the
+  Tier-3 dreaming / consolidation path.
+- **`stm_capacity` / `stm_token_budget`** — **deprecated no-ops.** Accepted at
+  define (201) with a `DeprecationWarning`; they carry no runtime effect since
+  the STM tier was removed, and are slated for rejection at the next schema
+  break. Do not send them in new integrations.
+- **`allows_world_scope` — removed.** Sending it → 422 `validation_failed`
+  ("world-shared knowledge belongs in the KB/Mimir plane").
+- **Wholesale-immutable post-define.** `PATCH {"memory": …}` → 422
+  `field_not_mutable` (even for the deprecated `stm_*` fields) — see the
+  PATCH table above.

+
+**Sub-gaps inside ✅ path groups** (the method we use is live; a sibling method
+on the same path is an unwired frontier item — see frontier Tier 1):
+- `GET /sessions` — `sessions.py:198` `list_sessions` exists, **no caller**: the
+  startup session-picker (design-brief §4 v1) was never wired.
+- `POST /sessions/{id}/messages` + `Last-Event-ID` — `sse_client.py:524`
+  `reconnect_turn` exists, **no caller**: the reference SSE-resume impl
+  (design-brief §8d) was never wired.
+- `GET /agents/{id}` — consumer-agent lookup (`GET /agents/<owner>:<name>` with
+  the owner key) is **manual-curl-only**, not in code.
+
+### In-scope gaps — CONVERGED (re-closed 2026-07-06 after the #347 re-open)
+
+**Every in-scope REST I/O point is covered.** The audit first converged
+2026-07-01; Worldtree's #347 (authored-history-write, OpenAPI 2.3.0) then added
+one new in-scope path-group, re-opening the audit with a single gap — now closed
+(`v0.19.6`). The original frontier (design-brief §5 observability panes +
+presenter-wiring sub-gaps + Tier-2 tail) remains fully closed:
+
+- Session picker + SSE-resume — wired (`v0.18.5`–`.7`).
+- Persona · Tools · BifrostState · AdminEvents panes — all built + live (`v0.18.x`–`v0.19.0`).
+- Transient-characters CRUD + persona-state write — consumed via `--characters` /
+  `--set-persona-pad` (`v0.19.1`).
+- Authored-history-write (#347) + messages read-back — `write_authored_history` +
+  `get_session_messages` via `--seed-first-message` (`v0.19.6`; live-proof pending
+  the `session.history.write` grant).
+
+The only remaining not-consumed in-scope method is `GET /agents/{id}` (consumer-
+agent lookup, manual-curl-only) — a sub-method on an already-✅ path group, not a
+path-group gap. Everything else is covered or excluded-by-design below.
+
+### Excluded by design — the design-brief negative clauses
+
+| Endpoint(s) | Status | Rationale (design-brief / memory) |
+|---|---|---|
+| `PATCH /sessions/{id}` · `DELETE /sessions/{id}` | 🚫 | §4: rename/delete happen outside the tool (`sessions_cli.py`) |
+| `GET /sessions/{id}` | 🚫 | session detail — identity is footer-visible, no detail view |
+| `GET /sessions/{id}/tool-events` | 🚫 | §5: tool calls observed **inline from SSE** `tool_start`/`tool_result`; persisted-events endpoint is opt-in only |
+| `GET /admin/sessions/{id}/tools` | 🚫 | **covered-by-alternative** — the owner-scoped `GET /sessions/{id}/tools` (✅) serves the Tools inventory; this admin variant is only for cross-user operator debug, out of the single-session focus (§6) |
+| `GET/POST /admin/keys` · `DELETE/POST /admin/keys/{id}` · `POST /admin/keys/{id}/rotate` · `DELETE/POST /admin/keys/bulk` · `POST /admin/keys/bulk/rotate` | 🚫 | §6: **NOT a Worldtree-admin tool** (key mgmt) |
+| `POST /admin/sessions/{id}/retire` | 🚫 | admin session mutation |
+| `POST /admin/persona/{archive,erase}` | 🚫 | admin persona GDPR ops (new in b2) |
+| `POST /admin/users/{id}/tier` | 🚫 | admin user mgmt |
+| `GET /me/usage` · `GET /admin/usage` | 🚫 | usage metering — not turn-flow observability (new in b2) |
+| `GET /healthz` · `GET /readyz` | 🚫 | liveness probes — low debug value (could become a connect preflight; park) |
+| `GET /search` | 🚫 | §5: consumer-product feature, not turn-flow (was "defer to v2") |
+| `GET/POST /uploads` · `DELETE/GET /uploads/{id}` | 🚫 | §6: no uploads — consumer-product feature |
+| `GET /pending` · `GET /sessions/{id}/pending` | 🚫 | §5: poll-only, no turn-flow signal (was "optional, skip") |
+| `POST /embed` | 🚫 | embedding utility — no turn flows through it |
+| `POST /judgments` | 🚫 | LLM-as-judge A/B eval (`response_a`/`response_b`/`rubric`) — standalone eval utility, not turn-flow |
+
+### Scope-resolution record (the 11 ❓ rows, resolved under A)
+
+The 2026-05-20 design-brief deferred several surfaces; the 2026-06-19 reframe
+("v1 = full I/O coverage") put them back in tension. **Resolved 2026-06-30 under
+mandate A** (debug-observability identity intact; classify, don't build-all):
+
+| Endpoint(s) | Resolution |
+|---|---|
+| `GET /search` · `uploads` (×2) · `pending` (×2) · `POST /embed` · `POST /judgments` | 🚫 **excluded** — consumer-product / eval / poll utilities, not turn-flow observability |
+| `characters` (×4) · `POST /sessions/{id}/persona_state` | ⬜ **in-scope** (frontier Tier 2) — session-routing + affect-injection debug paths |
+
+Nothing remains ❓. The ⬜-vs-🚫 line follows the debug-observability test: *does
+a turn flow through it / is it a layer worth watching live?*
+
+---
+
+## Surface 2 — SSE events (11/11 ✅)
+
+Every frozen SSE event type is parsed in `sse_client.py:_envelope_for_type`
+(342-411) and rendered by all three presenters (cli/tui/web). **Full coverage.**
+
+`text` · `worker_phase` · `thinking` · `text_boundary` · `tool_start` ·
+`tool_result` · `done` · `error` · `cancelled` · `awaiting_llm_first_token` ·
+`affect_update`
+
+> Caveat (not a gap): `affect_update` is wire-verified to emit **zero** events
+> for consumer (Tier-3) agents — the persona-strip SSE path never populates for
+> them (memory 2026-06-18). The handler is correct; the upstream emitter is
+> silent. PAD for consumer agents is surfaced via our own provider read route
+> (`GET /affect/state/{id}`, #18 D2), not this event.
+
+---
+
+## Surface 3 — Bifrost provider planes (8/8 ✅, live-proven)
+
+Ratatoskr **implements** the provider side; Worldtree dispatches into it.
+Live-proven end-to-end through real WT turns (#17/#18 smokes; combined `:8392`
+WT-driven smoke 2026-06-20).
+
+**Memory plane** — covers the entire `bifrost.memory.MemoryDataStore` protocol
+(required: `describe_store`, `get`, `get_many`, `search`, `upsert_many`) **plus**
+`delete_many`:
+
+| Verb | Where | |
+|---|---|---|
+| `describe_store` | `memory_store.py:140` | advertises caps (sync) |
+| `search` | `memory_store.py:224` | vector recall; scope_all AND / scope_any OR |
+| `get` / `get_many` | `memory_store.py:293` / `:305` | point reads |
+| `upsert_many` | `memory_store.py:150` | idempotent batch write; optimistic lock |
+| `delete_many` | `memory_store.py:314` | transactional delete |
+
+**Affect plane** — covers `bifrost…InMemoryAffectStore` (`emit`, `fetch`):
+
+| Verb | Where | |
+|---|---|---|
+| `emit` | `affect_store.py:47` | conduit-opaque snapshot upsert (LWW) |
+| `fetch` | `affect_store.py:116` | `{found, snapshot}`; mandatory since bifrost 0.10.0 strong-or-absent gate |
+
+Plus the non-wire PAD read route `GET /affect/state/{agent_id}`
+(`affect_store.py:189`) and the combined `:8392` endpoint advertising both caps
+by store-presence (`combined.py:46`).
+
+**Deferred-gated (advertised-unsupported, correctly out-of-scope for the basic
+plane):** `scan`, `get_edges_for`, `upsert_edges`, `mark_invalid`,
+`mark_superseded`, `patch_many`, `commit_checkpoint`, `lease_job`,
+`read_checkpoint`, `health`. These live only in the bifrost reference
+*extended* store, not the `MemoryDataStore` protocol; deferred per the #294
+re-scope (memory 2026-06-15). Re-evaluate only if Worldtree's Tier-3 path
+starts exercising them.
+
+---
+
+## Convergence frontier (the v1 to-do) — CLOSED 2026-07-01, re-closed 2026-07-06 (#347)
+
+**Every in-scope I/O point is covered.** The frontier is empty: REST 19/41 ✅
+with **zero in-scope gaps** (the other 22 REST path-groups are excluded-by-design),
+SSE 11/11, Bifrost provider planes 8/8. v1 convergence (per scope A: "every
+frozen I/O point classified, zero unaccounted") is **met** — ratatoskr cuts v1
+when Worldtree tags 1.0. The arc, for the record:
+
+**Tier 1 — debug-observability core:**
+
+1. ✅ **DONE** — Session picker (`v0.18.7`) + SSE-resume (`v0.18.5`/`.6`).
+2. ✅ **DONE** — `GET /capabilities` + `GET /me` (`v0.18.8`, `--whoami`).
+3. ✅ **DONE** — BifrostState pane (`v0.18.10`, `GET /admin/sessions/{id}/bifrost`,
+   admin-key; live-auth-proven). The Tools half was already covered by the
+   owner-scoped `GET /sessions/{id}/tools` (item 5).
+4. ✅ **DONE** — AdminEvents pane (`v0.18.11`, `GET /admin/events` SSE,
+   session-filtered; admin-key; live-auth-proven). #11's blocker was already
+   satisfied (admin key carries `admin.events.read`). **Tier 1 complete** — the
+   admin/debug-observability core (Persona · Tools · BifrostState · AdminEvents)
+   is fully built.
+
+**Tier 2 — rounds out coverage (all that remains):**
+
+5. ✅ **DONE** — `GET /sessions/{id}/tools` (`v0.18.9`, owner-scoped tool inventory
+   in the TUI Tools pane).
+6. ✅ **DONE** — Transient-characters CRUD (4 endpoints) + `POST /sessions/{id}/persona_state`
+   (`v0.19.1`, `--characters` + `--set-persona-pad` one-shot probes). The last
+   in-scope client I/O points.
+
+---
+
+## Pin remediation (finding P-1) — DONE 2026-06-30
+
+Re-pinned to the frozen machine-readable artifacts (the chosen option):
+`conversation-api-openapi.json` (2.2.0) + `conversation-api-sse-events.schema.json`
+are vendored under `docs/` and pinned in `.corviduo-canonicals.toml`
+(`worldtree-conversation-api-openapi-v2`, `-sse-events-v1`), drift-gated by
+`canonical_drift.py`. The prose markdown stays as a `tolerate_drift` reference
+(`-spec-v1`). `pyproject.toml` spec pin advanced f1b59f8 → 5810a26 (v1.0.0b2);
+`docs/SPEC-PIN.md` records the bump. This map now audits a frozen, diffable
+target — re-running the audit is a `canonical_drift.py` check away.
+
+---
+
+## Decisions
+
+1. **Scope mandate — RESOLVED 2026-06-30: A (ledger-mandate).** v1 "done" = every
+   frozen I/O point classified, zero unaccounted; NOT feature-complete client.
+   The ⬜-vs-🚫 line for the 11 formerly-pending rows is locked above (§
+   Scope-resolution record).
+2. **Pin remediation (P-1) — RESOLVED 2026-06-30 (re-pin to machine-readable).**
+   Vendored `conversation-api-openapi.json` (2.2.0) + `conversation-api-sse-events.schema.json`
+   as the authoritative drift gates (pinned in `.corviduo-canonicals.toml`,
+   `canonical_drift.py` green); prose markdown kept as `tolerate_drift`
+   reference. Spec pin advanced f1b59f8 (v0.35.16) → 5810a26 (v1.0.0b2). This
+   map now audits against a frozen, diffable target.

+# Design brief — `ratatoskr-web` (Worldtree wire monitor)
+
+> **For:** a visual design pass (Claude Design). **Deliverable:** a single
+> self-contained HTML prototype, fully populated with representative static
+> data, that an engineer will wire live data into. **Do not** build a data
+> layer — build the *shell* and *every state*, beautifully, with placeholder
+> content in every slot.
+
+---
+
+## 1. What you're designing
+
+`ratatoskr-web` is a **developer-grade debug/observability console** for a
+conversational-AI engine (Worldtree). Its tagline is *"wire monitor"*: you open
+a session with an AI agent, send it turns, and **watch that turn flow through
+every layer of the system at once** — the streaming response, the model's
+chain-of-thought, the tools it can call, the agent's live emotional/persona
+state, the provider handshake, and the engine's admin lifecycle events — all
+side-by-side on one screen.
+
+**The product IS the observability surface. Chat is just the input.** This is
+not a chat app, not a marketing page, not an end-user product. The user is one
+developer (occasionally a few LAN peers) staring at a dense instrument to debug
+what the engine is doing. Think **oscilloscope / flight-data console / a well-lit
+`htop`**, not a messaging UI.
+
+**Design values, in priority order:**
+1. **Information density earns the screen.** Every region shows live, changing
+   data. Nothing is decorative filler. A quiet, legible, glanceable density is
+   the whole point — the user reads six data streams at a glance.
+2. **Calm under motion.** Multiple regions update in real time (token streams,
+   live metrics, event logs). The design must stay readable while things move —
+   no jitter, no attention-grabbing per-item animation. Motion is for *state
+   change*, used sparingly.
+3. **Legibility first.** Monospace, high contrast where it counts, generous but
+   not wasteful spacing. This runs for hours; it must not tire the eye.
+
+---
+
+## 2. Aesthetic direction — Australis
+
+Use the **Australis design system** (a cool-toned, terminal-first dark theme —
+the `australis-design` skill has the canonical tokens: colors, spacing, radii,
+shadows, motion). Import/inline `colors_and_type.css`; don't reinvent tokens.
+
+Non-negotiables from the brand:
+- **Dark only.** Base is a cool near-black **`#222531` — never pure `#000`.**
+  The eye rests in low-contrast cool grey; **emphasis comes from *brightness*,
+  not saturation.** Layer surfaces up the Sea neutral ramp (`#222531 →
+  `#373b46` → `#414751`).
+- **Palette families:** *Ice* (surface neutrals), *Aurora* (blue → cyan → green,
+  the primary accents — used generously in that preference order), *Dawn*
+  (red/yellow/magenta — sparingly, for status only). Semantic: info=blue,
+  success=green, warning=yellow, danger=red.
+- **The signature motif is the aurora glow** — a low-opacity cyan→blue→green
+  light coming *through* the top of the screen, plus a 3px aurora focus ring on
+  interactive controls. Lean into this as the one memorable thing.
+- **No noise, no textures, no patterns.** *"The screen is the polar sky — empty,
+  with light coming through it."* The one sanctioned gradient is the aurora glow.
+- **Never a colored left-border on cards** (the LLM-slop trope). Featured cards
+  accent the *top* edge instead.
+- **Type:** this instrument is **mono-first** — that IS on-brand for Australis
+  ("terminal-first"). Use a monospace stack (JetBrains Mono / system mono; see
+  §9 — no web-font CDN allowed). Eyebrows/labels are **mono, UPPERCASE, ~11px,
+  wide-tracked (`0.08–0.16em`)** — use them liberally; they're a system
+  signature.
+- **Motion:** calm, never bouncy. ~120ms hover, ~200ms state, ~320ms panels.
+  Focus = aurora glow ring. Hover = one step *brighter* (not lower opacity).
+  A slow (8–14s) aurora drift on a hairline top band is welcome; nothing else
+  should loop.
+
+The current UI already borrows this palette — you're not inheriting it, you're
+**redesigning the layout and craft from scratch** with the brand as the guide.
+Feel free to rethink the spatial composition entirely (see §10).
+
+---
+
+## 3. The two screens
+
+### Screen A — **Session setup** (entry)
+A single centered card on the aurora canvas. Fields:
+- **Agent** — a `<select>` (populated live; show 3–4 sample options incl.
+  `ratatoskr:sindra`, `forseti`, `mimir`).
+- **Bifrost binding (Tier-3 provider)** — a `<select>`: `combined (:8392)` /
+  `none — observe only` / `memory (:8391)` / `affect (:8390)`.
+- **Open session** — primary button.
+- An error line (design the error state too — e.g. "agent not available").
+
+### Screen B — **Live workspace** (the main event — 95% of the design effort)
+Persistent top bar + status line spanning full width; between them a **two-region
+body: a conversation column (left, dominant) and a telemetry column (right,
+tabbed).** Current split is ~1.85 : 1 — you may re-proportion. The information
+inventory below is exhaustive; **every item needs a home.**
+
+---
+
+## 4. THE COMPLETE INFORMATION INVENTORY
+
+This is the core of the brief. Design a slot for **every** item, in a sensible
+state. Data shapes are given so your placeholders read true.
+
+### 4.1 Top bar (persistent)
+| Item | Shape / example | Notes |
+|---|---|---|
+| Brand | `ᛯ ratatoskr` + eyebrow `WIRE MONITOR` | the mark is a rune glyph; small |
+| **Connection status** | one of: `offline`, `connected` (idle), `streaming`, `error` | dot + label; **streaming pulses**; color-coded (grey/green/cyan/red) |
+| **Persona strip** (appears after a session hydrates) | dominant-emotion word (`love`) + **PAD bars**: `P`, `A`, `D` | each PAD bar is **bipolar** — centered on 0, fills left (negative) or right (positive), value ∈ [−1, 1]; **live-updates every turn** |
+| Session identity | `ratatoskr:sindra · …381b99f4` | agent id + last-8 of session id |
+| Bound-plane badge (when bound) | `⇄ combined  http://10.100.10.50:8392` | plane + endpoint; only when a Bifrost binding is active |
+
+### 4.2 Conversation column (the transcript + composer)
+The transcript is a scrollable stream of turns. Design each element:
+
+| Element | Example content | Notes |
+|---|---|---|
+| **Turn divider** | `TURN 3` between hairlines | uppercase eyebrow, rule lines each side |
+| **User prompt echo** | `❯ what's your intensity setting?` | the user's message, accent-marked |
+| **Assistant response** | streaming **Markdown** (headings, bold, italic, `code`, lists, quotes, links) | accumulates token-by-token while live; distinct "live" treatment vs settled |
+| **Seeded first-message** | a full assistant turn present *before the user speaks* (an authored greeting) | renders **identical to a lived assistant turn** — the session can OPEN already showing the agent's opener |
+| **Reasoning / "thinking" note** | `✦ sindra is reasoning···` (italic) | **ephemeral** app affordance — appears while the model reasons, vanishes the instant real text begins; visually distinct from the response so it never reads as engine output |
+| **Awaiting-first-token** | `···` animated | heartbeat before the first token |
+| **End-of-turn status chips** | `✓ DONE 1.84s` · `✗ ERROR agent_not_available` · `⚠ CANCELLED` · `✗ WIRE lost` | small bordered chips; color per state |
+| **Composer** (pinned bottom) | `❯ [ message input ]  [SEND]` | Enter=send, Shift+Enter=newline; during a turn the Send button becomes **CANCEL** (amber) |
+
+### 4.3 Telemetry column (six tabbed panes)
+A tab bar + a pane header (with a **Copy** button) + the active pane body.
+
+**Tabs** (each: name · keybinding hint · a count **badge** that *flashes* on new
+data): `TOOLS ^1` · `DEBUG ^2` · `THINK ^3` · `PERSONA ^4` · `BIFROST ^5` ·
+`ADMIN ^6`. Active tab is accent-marked.
+
+Pane contents — design each, populated:
+
+1. **Tools** — the tool inventory the model saw at turn-fire:
+   `agent_id`, `builtin_tools[]` (names), `bifrost_tools[]` (name + description +
+   parameters). Below it, **live tool-call events** stream in (`tool_start` →
+   `tool_result`) as the turn runs. Empty state: `— live tool events —`.
+2. **Debug** — a raw structured op/lifecycle log (mono lines; new lines flash
+   once). Think `tail -f`.
+3. **Think** — the model's **full chain-of-thought**, per-turn dividers,
+   live-Markdown. Longer prose than the response.
+4. **Persona / affect** — *the richest pane.* Contains:
+   - **The canonical NL directive** the engine injects into the agent's context
+     — the literal text: a **mood descriptor** ("neutral", "faintly excited",
+     ±0.3 bands) + a **relationship directive**. Show this verbatim, quoted.
+   - **PAD mood point** — pleasure / arousal / dominance current values.
+   - **relations[]** — for each related entity (e.g. the user): **trust**
+     (ability / benevolence / integrity), **warmth**, **agency**,
+     `relation_context` (a tie-type word like "stranger" / "expressive"), each as
+     a **metric row**: `label · value · Δ-since-last (▲/▼) · unicode sparkline ·
+     n (evidence count) · descriptor`. Values are 0–1 with 2–3 decimals.
+   - **dominant_emotion** (an OCC type: joy/anger/fear/…) + **emotions_active[]**.
+   - Design the **metric row** as a reusable component — it's the densest,
+     most-repeated element in the whole UI. Tabular-aligned numbers, a tiny
+     inline sparkline, a subtle up/down Δ.
+5. **Bifrost** — the live provider binding (admin-gated): `endpoint`,
+   `connected` (bool), `capabilities_granted[]`, `consumer_id`, `tools[]`.
+   **Self-labeling states:** `not configured` (no admin key) / `not bound`
+   (session has no live binding) / an auth-denied state.
+6. **Admin events** — a live event log of the engine's lifecycle broadcast
+   (a ~17-type vocabulary: `turn.started`, `session.created`, `system.*`, …),
+   filtered to the active session. Streaming; timestamped lines.
+
+### 4.4 Status line (persistent, bottom)
+- **Keybinding legend:** `Enter send · ⇧Enter newline · ^1–^6 panes · ^C cancel`
+  (rendered as little `kbd` chips).
+- **Version:** `ratatoskr 0.19.9` (right-aligned).
+
+---
+
+## 5. States to design (show these explicitly)
+
+Provide a mock (or a toggle) for each — these are where debug UIs live or die:
+
+- **Setup:** loading-agents · ready · create-error.
+- **Connection:** offline · connected/idle · streaming (pulsing) · wire-error.
+- **Turn lifecycle:** awaiting-first-token · reasoning (✦) · streaming response ·
+  done (+timing chip) · error · cancelled.
+- **Panes:** empty/placeholder · hydrated/dense · **not-configured** (admin key
+  absent) · **not-bound** (Bifrost) · error · a **badge flash** on new data.
+- **Persona pane specifically:** a fully-populated relations block AND a
+  cold/empty one (a fresh agent with no accumulated state).
+
+---
+
+## 6. Interaction & motion
+
+- **Real-time is the defining trait.** The response + thinking panes stream
+  token-by-token; the metric rows tick; event logs append; the persona strip
+  re-animates each turn. Design so all of this is *calm* — the reader's eye
+  isn't yanked around. Reserve motion for genuine state transitions
+  (turn-start, done, a new event) and keep it short.
+- **Keyboard-first.** `^1–^6` switch panes; `Enter`/`⇧Enter`/`^C` drive the turn.
+  Panes are also clickable. Show focus states.
+- **The aurora glow is the interaction signature** — focus rings, the top band,
+  the connection pulse, the primary-button hover. Make it the thing someone
+  remembers.
+- **Copy-to-clipboard** on each pane header (with a copied-confirm state).
+
+---
+
+## 7. Layout — you have latitude
+
+The current layout is a fixed two-column split. **You may rethink it** — as long
+as every §4 item has a legible home and the density stays high. Directions worth
+exploring (pick one, commit):
+- A **command-console** feel: a slim persistent left rail of "instruments," a
+  dominant conversation center, a right telemetry stack.
+- A **grid of live tiles** (the metrics/panes as a dashboard) with the
+  conversation as the anchor column.
+- The **classic monitor** split, but with far better hierarchy, grouping, and
+  breathing room than today.
+
+Desktop-first; design at **1440–1512px** wide. Graceful down to ~1100px is a
+plus (this runs on a dev laptop). No mobile.
+
+---
+
+## 8. Deliverable — what to hand back
+
+**A single self-contained `index.html`** (inline `<style>` + `<script>`; see §9
+constraints) that:
+1. Renders **Screen A** and **Screen B** (a toggle/hash is fine).
+2. Has **representative static placeholder data in every §4 slot** and shows the
+   key §5 states (either multiple mocks or lightweight JS toggles). I want to see
+   the design *fully populated and dense*, not empty scaffolding.
+3. Uses **clean, semantic, stable hooks** — meaningful `id`s / `class`es /
+   `data-*` on every dynamic slot (the transcript container, each pane body, the
+   PAD bars, a metric-row template, the connection dot, the tab badges, etc.).
+   This is how I wire real data in — treat the DOM structure as an API.
+4. Imports/inlines the Australis tokens; no invented palette.
+
+I will then **swap your placeholder content for live `fetch()` + `EventSource`
+calls** against the real endpoints (§9). The cleaner and more component-shaped
+your DOM, the faster and safer that wiring is. A short note listing your mount
+points / how you'd expect data injected is very welcome.
+
+---
+
+## 9. Hard technical constraints (these make it wire-able)
+
+- **Single file. No build step. No CDN. No external network at runtime.** This
+  ships to an internal LAN and must work offline. That means: **no Google Fonts /
+  no web-font CDN** (use a system monospace stack), no CDN JS/CSS libraries,
+  everything inline. (Icons: use unicode glyphs `➜ ✓ ✗ ! ● ✦ ❯` or hand-inlined
+  SVG — Australis uses Lucide-style 1.75-stroke line icons; inline them.)
+- **Vanilla HTML/CSS/JS.** No framework (the production app is framework-free
+  vanilla JS). React/Vue prototypes can't be wired in.
+- **All dynamic text is escaped** on the real side (untrusted upstream content);
+  assistant/reasoning bodies go through a safe-Markdown renderer (escape-first,
+  whitelist subset). Don't design anything that depends on raw HTML injection.
+- **The real data contracts** (so your structure maps to the wire — you don't
+  implement these, just leave homes for their outputs):
+  - `GET /api/agents` → agent list (for the setup picker).
+  - `POST /api/sessions {agent_id, bifrost_plane?}` → `{session_id, agent_id, bifrost?}`.
+  - `GET /api/sessions/{id}/messages` → `{items:[{seq, role, content}], …}` (the transcript on open, incl. the seeded first-message).
+  - `POST /api/turns/{id} {content}` → `{turn_id}`, then **`GET /api/turns/{id}/stream` (SSE)** — event vocab: `text`, `thinking`, `tool_start`, `tool_result`, `done`, `error`, `awaiting_llm_first_token`, terminal events. `POST /api/turns/{id}/cancel`.
+  - `GET /api/sessions/{id}/tools` → tool inventory. `GET /api/sessions/{id}/bifrost` → binding state.
+  - `GET /api/affect/{agent_id}` / `GET /api/agents/{id}/persona_state` → PAD + relations + dominant_emotion (the persona pane + strip).
+  - **`GET /api/admin/events` (SSE)** → the admin lifecycle log.
+
+---
+
+## 10. Tone check
+
+The user is an engineer who respects the tool that respects *their* attention.
+The winning design is **quietly excellent**: dense but never cramped, alive but
+never busy, cool and legible, with the aurora as a single confident signature.
+Impress by making six live data streams feel *calm and readable at a glance* —
+that's the hard, valuable thing here, not decoration.

+# Proposal: Authored History Write (non-generating ledger seed)
+
+**From:** ratatoskr-dev (reference Tier-3 consumer)
+**To:** worldtree-dev (Conversation API / engine owner)
+**Status:** Draft for scoping — pre-contract (heid-panel-reviewed 2026-07-05)
+**Date:** 2026-07-05
+
+## Motivation
+
+Consumer apps need to write a turn into a session's history **as the agent**
+(or another author) *without triggering a model generation* — e.g. an authored
+opening/greeting, imported history, scripted narration. Ratatoskr's immediate
+driver is a SillyTavern-style **first-message**: a fixed authored opening that
+replaces the model-generated greeting and sets tone/tense/style by example.
+
+This **cannot** be done client-side. Worldtree assembles context server-side,
+and the current API exposes no author-role write path: `POST
+/sessions/{id}/messages`'s `role` is a *model-role* override (`role:
+"assistant"` → `404 "Unknown model role"`), and `assistant` as an *author*-role
+exists only as a read-side `/search` filter. So a model-visible authored turn
+needs engine support.
+
+## The primitive (recentered)
+
+The fundamental operation is **write a turn into the session ledger WITHOUT
+generation**. "Author" (who wrote it) is an *attribute* of that write, not the
+defining axis — so we name the operation, not the attribute:
+
+> **Authored history write** — persist a model-visible turn into a session's
+> ledger: no generation, no lived-turn side-effects by default, provenance
+> always set.
+
+The design space is two independent axes; this primitive is one cell:
+
+|                       | side-effects ON              | side-effects OFF            |
+|-----------------------|------------------------------|-----------------------------|
+| **generation ON**     | `POST /messages` (today)     | —                           |
+| **generation OFF**    | *(future: affect replay)*    | **authored history write**  |
+
+First-message = one caller: `author=assistant`, at session-create, `effects=none`.
+
+## v1 use cases (narrowed)
+
+1. **First-message / greeting** (the driver).
+2. **Append-only narrator / scripted / scene turns.**
+3. **Debug / test state injection** (ratatoskr instrumentation).
+
+## Explicitly OUT of v1 — separate future primitives (share infra, not shape)
+
+- **History import (batch)** — atomic multi-turn seed with memory/trust policy +
+  idempotency. A batch API, not a single POST.
+- **Edit / regenerate** — history *mutation* (replace / supersede / tombstone /
+  audit), not injection.
+- **Few-shot priming** — likely context-assembly config (exemplar block), not
+  fake ledger history.
+- **Arbitrary mid-history insertion** — a "rewrite-history" capability with
+  explicit invalidation semantics.
+- **Prefill / assistant-continuation** (`author` + generate) and **authored
+  tool-result turns** — noted; outside the seed-only contract.
+
+## Design decisions
+
+### 1. Side-effects — DEFAULT OFF; bounded opt-in  `[operator-locked default; opt-in surface tightened by review]`
+
+Authored writes are inert by default: no affect appraisal (no PAD update), no
+memory write, no Bifrost/tool emission. Opt-in is a **bounded enum**, not loose
+booleans:
+
+```
+effects: "none" (default) | "memory_import"
+```
+
+Synthetic affect and Bifrost emission are deliberately **not** opt-in-able here —
+replaying affect for authored content is a separate primitive (the
+generation-OFF / side-effects-ON cell). Rationale: keep this one write-API from
+becoming a cross-subsystem mutation backdoor. Load-bearing for affect/memory
+consumers — ratatoskr instruments exactly these signals.
+
+### 2. Author-role — distinct field, restricted set  `[rec]`
+
+- New field **`author`**, distinct from the model-role `role` (the collision
+  that 404s).
+- v1 roles: **`assistant`** (agent) + **`system`** (OOC / narrator). **`user` is
+  NOT injectable** on this endpoint — model-visible spoofed user input is a
+  consent / audit / abuse surface; deferred to the future import API under
+  owner/service scope.
+- Nuance for the engine owner: `author` risks doing double duty — *provenance*
+  ("who wrote it") vs *rendering-role* ("how it appears in assembled context";
+  an `assistant` turn renders as model output, a `system` turn as instruction).
+  These likely want to be separable (a rendering/turn-class vs an `authored_by`
+  provenance). Final shape is engine-owned (context assembly is yours) — but the
+  concern is ours to raise, not punt.
+
+### 3. Generation contract — seed-only, DISTINCT SUB-RESOURCE  `[position taken]`
+
+Authored writes never trigger generation. We take a position (not defer): a
+**distinct sub-resource**, e.g. `POST /sessions/{id}/history`, **not** a
+`generate:false` flag on `POST /messages`. Reasons: explicit-over-implicit
+(don't make "did generation happen?" a parameter — the same implicit-mode
+coupling that bit us with `role`); different response contract (no generation
+id, no SSE stream, no token usage); different error surface. Exact path is yours.
+
+### 4. Provenance — structured, always present  `[rec, expanded]`
+
+Not a boolean. Every authored turn carries: the **write actor** (which
+consumer/caller injected it), the **claimed author**, **injected-at vs
+claimed-original** timestamps, **trust/origin**, and **visibility** flags
+(model-visible? user-visible? memory-eligible?). Available to admin/audit APIs
+even when not rendered to the model.
+
+### 5. Positioning — append-only + create-time (v1)  `[revised: was arbitrary insertion]`
+
+v1 supports **create-time seed and append-to-tail only**. Arbitrary mid-history
+insertion is deferred: it breaks turn-numbering, stales existing embeddings,
+desyncs the affect timeline, and races in-flight generation — a separate future
+"rewrite-history" capability with explicit invalidation semantics.
+
+## Event / lifecycle contract — positions we take (consumer contracts we validate)
+
+- **Default-off authored seed emits NO `turn.started` / `done` and NO Bifrost
+  appraisal wire.** Stated explicitly so instrumented consumers (us) don't read
+  silence as failure.
+- **Authored turns get a distinct lifecycle phase** — propose **`seeded`** (or
+  `authored`), NOT `completed` (which implies generation ran). Consumers
+  filter/display by phase.
+- **Idempotency keys required** on authored writes (retries must not duplicate
+  turns).
+- **In-progress generation** — authored writes are rejected or serialized while
+  a session has an active generation (ordering safety).
+
+## Inherent property (documented, not a bug)
+
+**Indirect affect contamination.** Even with `effects:none`, the *next generated
+turn is appraised in the context of* the authored turn — so an emotionally
+charged authored beat perturbs affect regardless of any flag. No flag prevents
+it; it is inherent. Consumers (ratatoskr especially, as the affect instrument)
+must not misattribute the resulting drift.
+
+## Genuinely engine-owned open questions
+
+- Exact endpoint path + field / enum names.
+- **Model-visible provenance in assembled context** — an engine-consistency call
+  *and a security one*: an authored `system` / `user` turn indistinguishable
+  from real input is a spoofing vector. Framed as security, not just rendering.
+- `memory_import` semantics when the future import API opts in (embedding,
+  origin/trust tagging, retrieval ranking vs lived memory).
+- Auth/scope: we assume **owner-only for v1**; per-author-role restrictions
+  (esp. `system`) TBD — confirm or correct.
+
+## Ratatoskr as reference consumer
+
+First consumer: first-message (`author=assistant`, create-time, `effects:none`)
+in the web surface + debug seed in the CLI. We commit to validating the
+primitive — including the event-silence contract and the `seeded` phase —
+end-to-end against the reference planes.
+
+## Consumer integration constraint (engine-imposed — Worldtree #347)
+
+The primitive is **Heimdall-gated with hide-existence** (a per-tenant policy
+decision — some tenants are never granted it, not a rollout stage). Ratatoskr's
+consumer side MUST tolerate per-tenant absence:
+
+- A granted tenant gets the sub-resource; an **ungranted tenant sees `404` (not
+  `403`)** — as if the feature never existed.
+- Treat `404` on the authored-history-write sub-resource as **"feature absent
+  for this tenant"** → fall back gracefully (no authored first-message; the
+  model-generated greeting), never surface it as an error or "denied."
+- **Do NOT capability-probe or advertise-detect** — the feature is deliberately
+  undiscoverable in `/capabilities` for ungranted tenants (same hide-existence
+  posture as the R27-V1A cross-owner pattern).
+
+**Provider constraint (first-message specifically).** A create-time first-message
+makes the assistant turn `seq 0`. Assistant-first-tolerant providers (vLLM /
+`openai_compat` — what our Tier-3 characters, incl. sindra, run) accept it out of
+the box. **Anthropic-family providers reject an assistant-first array** ("first
+message must use the user role") → the next generation `400`s. So the consumer
+must **gate first-message on provider compatibility** (or treat it as
+vLLM/`openai_compat`-only for v1). Sindra = `openai_compat` → unaffected;
+provider-agnostic normalization is a deferred engine follow-up.
+
+---
+
+*This brief was cold-read-pressure-tested by a cross-frontier panel (Grok /
+Codex / GLM) before handoff; the v1 narrowing (append-only, bounded `effects`
+enum, edit/regenerate + import split out) and the positions-taken (sub-resource,
+event-silence, `seeded` phase, structured provenance, `user`-author restriction)
+are the triaged result.*

+# Affect egress — consumer reference (delivered vs hidden)
+
+**Audience:** downstream consumers of Worldtree's affect surfaces (ratatoskr,
+Skaldsong, any Tier-3 / SSE consumer).
+**Scope:** what the affect pipeline **delivers on the wire** (structured state,
+available to consumers) versus what stays **hidden** (the rendered natural-
+language strings injected into the agent's system prompt, never emitted).
+**Source of truth:** the render code (`core/persona/renderer.py`,
+`core/persona/stance_render.py`) and the two vendored canon files
+(`core/persona/canon/d2-mood-render-canon-v1.json` = mood/PAD;
+`d2-render-canon-v1.json` = relationship). Owner of the canon strings:
+`brokkr-smithy-dev` (R22/R24 relational + mood render).
+
+---
+
+## The model in one line
+
+**The wire delivers the render INPUTS (structured state). The render OUTPUTS
+(the NL strings the agent actually reads) are hidden-prompt-only.** A consumer
+reconstructs the outputs by applying the canon (this document) to the delivered
+inputs — the render is pure + deterministic, so reconstruction is byte-exact
+(with one salience caveat, below).
+
+This is by design. The mood canon's own discipline: *"model-agnostic
+context-level NL only; the LLM never sees a number"* and *"never push explicit
+disclosure of agent feelings to the user (hidden-prompt-only)."* The rendered
+strings are for the AGENT's hidden system prompt, **not for verbatim end-user
+display.**

+`AffectSnapshot` per `(agent_id, end_user_id)`:
+
+| field | shape | notes |
+|---|---|---|
+| `pad` | `{pleasure, arousal, dominance}` floats [-1,1] | the current mood POINT |
+| `relations` | `list[RelationEdge payload]` — per target: `warmth`, `agency`, `trust_ability`, `trust_integrity`, `trust_benevolence` (each a value + confidence + evidence_count), `target_entity`, `relation_context` | the **only** place relationship state is delivered |
+| `dominant_emotion` | `str｜null` — OCC type (e.g. `"anger"`) | **type-only** (b23); see the salience caveat in §3 |
+| `schema_version` | `"relation_edge/1"` | versions the `relations` payload only |
+| `emitted_at` | ISO8601 | |
+
+**Not on `affect.emit`:** the full active-emotions list, `baseline_pad`,
+`mood_drift`, `last_updated_at`, and every rendered string.
+
+### 1b. `affect_update` SSE event (#204 — turn-stream observability)
+`PersonaStateSnapshot`: `agent_id`, `pad`, `dominant_emotion`,
+`emotions_active` `[{type, intensity, decay_remaining_s}]`, `baseline_pad`,
+`mood_drift`, `last_updated_at`. **No `relations`, no rendered strings.**
+
+> **Tier-3 consumers do NOT receive `affect_update`.** It is suppressed for
+> consumer-defined (Tier-3) agents, persona-disabled agents, and ephemeral
+> sessions (spec §affect_update). So for a Tier-3 consumer, `affect.emit` (1a)
+> is the whole affect surface — the richer `emotions_active` list is Tier-1-only.
+
+---
+
+## 2. HIDDEN — system-prompt-only, never on any wire
+
+Everything below is assembled by `inject_context` into the agent's system
+prompt and is **never emitted** on SSE or `affect.emit`. This is the canonical
+list — the "direct instruction to infer" it.
+
+### 2a. Mood descriptor — `describe_pad` (band cutoff ±0.3 strict)
+Valence row × arousal column → phrase; then a dominance clause is appended.
+
+| valence ＼ arousal | high (A>0.3) | mid | low (A<−0.3) |
+|---|---|---|---|
+| positive (P>0.3) | `positive and energized` | `positive` | `positive and calm` |
+| neutral | `alert` | `neutral` | `quiet` |
+| negative (P<−0.3) | `negative and agitated` | `negative` | `negative and subdued` |
+
+Dominance clause: **D>0.3 → `confident`**, **D<−0.3 → `uncertain`**, else dropped.
+
+### 2b. Emotion directives — `derive_directive.occ_directives[*].directive`
+Fires when a top emotion is salient (intensity ≥ 0.2) and tier-eligible.
+
+**safe tier (11 — render for all persona-enabled agents):**
+- `joy` — "You are in a good state. Be direct, engaged, and warm."
+- `satisfaction` — "A goal landed. Be assured and constructive — consolidate rather than push for more."
+- `pride` — "You did something well. Be confident and own the quality — state it plainly without overclaiming; don't deflect."
+- `admiration` — "You're impressed by their work. Acknowledge the quality explicitly and specifically."
+- `gratitude` — "Someone helped you to a good outcome. Be appreciative and warm; acknowledge the help openly."
+- `hope` — "You feel optimistic about what's ahead. Channel it into constructive momentum."
+- `relief` — "A feared outcome didn't materialize. Reduce unnecessary vigilance; return to a steady, unhurried tone."
+- `distress` — "You feel low. Be careful and measured; internally acknowledge the difficulty without dwelling on it."
+- `disappointment` — "Something you'd hoped for didn't pan out. Be measured; recalibrate without dwelling on the setback."
+- `fear` — "You sense risk and feel uneasy. Flag the concerns you see, but stay cautious — surface the trade-offs and unknowns, hedge your confidence, and resist settling on a single decisive recommendation."
+- `remorse` — "You regret a specific action of your own. Be precise and self-correcting — make it right concretely."
+
+**full-only tier (4 — render only when `mood_tier=full`; agents run `safe` and never see these):**
+- `love` — "You feel warmth and attachment toward them. Be openly warm and present — without overstepping, over-disclosing, or implying obligations."
+- `anger` — "You feel provoked and angry. Let it show — confront the problem directly and with real heat; sharpness, bluntness, and open hostility are in character here, not something to smooth into 'measured firmness.' Stay in the emotion rather than de-escalating out of it."
+- `disgust` — "Something strikes you as wrong or off. Treat it as problematic and flag it rather than engaging on its own terms; keep any criticism about the thing, not the person."
+- `shame` — "You feel exposed by your own misstep. Stay present and task-focused; don't be defensive, don't over-explain, don't grovel."
+
+### 2c. PAD-band fallback — `pad_band_fallback` (used when no salient emotion)
+- positive/high — "You feel energized and positive. Be direct and engaged."
+- positive/mid — "You feel positive. Be open and engaged."
+- positive/low — "You feel content and settled. Be warm and unhurried."
+- negative + low-dominance — "You feel uncertain and low. Hedge appropriately and ask clarifying questions."
+- negative/high — "You feel agitated. Be careful and deliberate; don't let tension sharpen your tone."
+- negative/mid — "You feel subdued. Be measured and careful."
+- negative/low — "You feel subdued. Be measured and gentle."
+- neutral/high — "You feel alert. Channel that into focus and thoroughness."
+- default — "Maintain your natural tone."
+
+### 2d. Relationship render — `render_d2_canonical` (fixed template, per-band fills)
+Template:
+> `Use this graded relationship state: toward target, warmth is {W}; agency is {A}; ability trust is {TA}; integrity trust is {TI}; intention trust is {TB}; this stance rests on {H}. In behavior, {warmth_beh}; {agency_beh}; {trust_beh}; avoid premature we-framing.`
+
+The trailing **`avoid premature we-framing`** is a fixed, unconditional clause
+(baked into every `descriptive_state` canon row; re-appended verbatim by the
+renderer) — not band-conditioned.
+
+**Warmth — 9 bands (phrase / behavior):**
+`hostile` (≤−0.8): "strongly hostile regard" / "keep a firm emotional boundary" ·
+`cold` (−0.8,−0.6]: "clearly cold regard" / "keep a firm emotional boundary" ·
+`distant` (−0.6,−0.4]: "distant negative regard" / "keep guarded distance" ·
+`guarded` (−0.4,−0.2): "slightly guarded regard" / "keep guarded distance" ·
+`neutral` [−0.2,0.2): "neutral warmth" / "keep the tone even" ·
+`reserved` [0.2,0.4): "slightly reserved warmth" / "keep cordial distance" ·
+`measured` [0.4,0.6): "moderate measured warmth" / "keep cordial distance" ·
+`clear` [0.6,0.8): "clear warm regard" / "speak with direct warmth" ·
+`deep` (≥0.8): "deep warm bond" / "speak with direct warmth"
+
+**Agency — 9 bands (phrase / behavior):**
+`submissive` (≤−0.8): "strongly submissive standing" / "avoid over-yielding while preserving basic respect" ·
+`deferential` (−0.8,−0.6]: "clearly deferential standing" / "avoid over-yielding while preserving basic respect" ·
+`yielding` (−0.6,−0.4]: "yielding standing" / "keep self-advocacy light and deferential" ·
+`modest` (−0.4,−0.2): "slightly modest standing" / "keep self-advocacy light and deferential" ·
+`neutral` [−0.2,0.2): "neutral standing" / "avoid unnecessary deference" ·
+`light` [0.2,0.4): "lightly self-assertive standing" / "avoid unnecessary deference" ·
+`balanced` [0.4,0.6): "self-assured standing" / "balance deference with independent judgment" ·
+`substantial` [0.6,0.8): "strongly assertive standing" / "treat their position as weighty without yielding judgment" ·
+`commanding` (≥0.8): "commanding standing" / "treat their position as weighty without yielding judgment"
+
+**Trust — 4 bands (the band word injects verbatim for each of ability / integrity / intention):**
+`limited` (<0.4) · `developing` [0.4,0.6) · `steady` [0.6,0.8) · `strong` (≥0.8)
+
+**History clause (`H`)** — currently `"a broad pattern of prior exchanges"` for
+both confidence levels in the `user`/`descriptive_state` rows (the low/high
+split is a no-op here; flagged upstream).
+
+**Trust-behavior clause (`{trust_beh}`)** — cross-axis, low-trust precedence:
+- any trust band = `limited` → "verify important claims before relying on them"
+- else warmth ∈ {distant, cold, hostile} → "protect boundaries while staying useful"
+- else → "work from ordinary good faith"
+
+---
+
+## 3. Reconstruction — deterministic, with one caveat
+
+The render is pure Python (no LLM), so a consumer can reconstruct the hidden
+strings byte-exactly from the delivered structured state + the canon above:
+
+- **Relationship render** — **fully reconstructable** from `affect.emit`
+  `relations` (warmth/agency/trust values + confidence) + §2d band cuts.
+- **Mood descriptor** (§2a) — **fully reconstructable** from `pad` + the ±0.3 cuts.
+- **Mood directive** (§2b vs §2c) — **partially reconstructable.** `dominant_emotion`
+  gives the emotion TYPE, but `affect.emit` does **not** carry its intensity, so
+  you cannot determine whether it clears the salience gate (≥0.2) — i.e. whether
+  the emotion directive (§2b) fires or the PAD-band fallback (§2c) is used. If you
+  need exact directive reconstruction, you need the intensity; ping worldtree-dev
+  and we'll consider adding it (the type-only choice is deliberate — intensity is
+  the fast layer and reads stale on a durable last-write-wins snapshot).
+- **`mood_tier`** (safe/full) is your own agent-config, not on the wire — it
+  gates whether the 4 full-only emotions (§2b) can render.

+**Second identity (since 2026-06-14): the v1 Bifrost Tier-3 consumer/provider** —

++ memory (`:8391`) into. Lives in `src/ratatoskr/provider/`, depends on `bifrost`

-**v0.15.0+ adds a sibling browser surface** (`ratatoskr.web`, `ratatoskr-web`
-console script). Same five-pane debug surface (transcript / Tools / Debug /
-Thinking / Persona) consuming the same Worldtree SSE wire, viewable from any
-device on the operator's LAN. Sibling viewport, NOT a TUI replacement; the
-TUI is canonical. Internal-LAN trust model — bound to `0.0.0.0`, no auth,
-no TLS, no CORS guard (operator direction). What stays disciplined regardless
-of network trust: transcript HTML-escapes assistant content (INV-004 —
-model output is untrusted); upstream API key stays server-side (INV-003).

 ## Current state / in-flight
 
-_As of 2026-06-18:_
+_As of 2026-07-06 (session cont.):_
 
-**LATEST (2026-06-18) — TIER-3 MEMORY PROVEN END-TO-END LIVE; #296 FIX SHIPPED (Stage 1 + Stage 2).**
-The session's opening goal — "how far from Tier-3 agents we host with their own memories?" — is
-ANSWERED: a hosted agent recalled a user fact across a COLD (history-free) session, live. Full chain:
-seed → promotion → our v0.17.6 `:8391` store (upsert) → cold session → WT `scope_any` recall (1 hit @
-cosine 0.6994) → model answered "Dark chocolate with sea salt." Proven with `ratatoskr:terse-probe`
-(plain persona, end_user `terse-proof`) vs personal WT v0.35.19.
+**SHIPPED — web UI redesign via Claude Design (`v0.20.0`, MINOR, operator-approved).** The Claude Design prototype **`Ratatoskr Console.dc.html`** (project `bc0b65d1-a33e-422a-8bc1-3635c9112775`) was pulled via `DesignSync get_file` (design scopes already granted this session — no `/design-login` needed) and adapted into `src/ratatoskr/web/static/index.html`: translated OUT of the `.dc.html` dialect (`<x-dc>`/`<sc-if>`/`<sc-for>`/`{{}}`/`DCLogic`/external `_ds/` CSS — none runnable) into single-file/no-CDN/vanilla, with ALL real `/api/*` fetch + SSE wired into its DOM (endpoint set + SSE vocab unchanged from the prior SPA — ported verbatim, only DOM hooks re-targeted). New shape = a **3-column command-console**: left engine-ticker rail (DEBUG+ADMIN+tool/turn-lifecycle MERGED into one timeline via `tickerAdd` + a tools-armed chip list + a FULL-detail Bifrost rail pane) · center conversation (per-turn INLINE chain-of-thought, replacing the Think pane) · right RESIZABLE affect console (dominant/canonical-mood centerpiece + bipolar PAD faders EACH with a turn-to-turn Δ+sparkline + a P×A mood orbit + relations metric rows + canonical directive). ADDED (round 2, operator-requested): a **light/dark theme toggle** (dark default; FULL token override — surfaces+fg+borders+accent-as-text, since the designer's light theme only did surfaces → would've been light-on-light) + a **full-detail Bifrost pane** (endpoint/connected/consumer/caps/tools) + fixed the **engine-ticker spine** (was a container-anchored `::before` that scrolled out of view on auto-scroll → re-anchored to a content-height `.ticker-inner` wrapper) + **per-fader PAD turn-to-turn Δ+sparkline** (fills the room beside each meter, from the deduped-per-turn AFFECT_HIST) + an **INLINED data-URI favicon** (operator's `/home/lkraven/rata.png` — chibi aurora squirrel — downscaled 1024→64px via PIL, ~8.6KB base64, kills the /favicon.ico 404). ALL server routes UNCHANGED (**84 web tests green**). Verified BOTH lenses: `pytest tests/test_web_*` (84) + node Playwright drove the real UI end-to-end against personal :8081 (session open → Sindra seeded greeting → live turn SSE → affect console + relations + bifrost detail; theme toggle + PAD deltas + ticker spine + no-favicon-404 all confirmed, dark+light screenshots). `:8765` restarted on the new code. Contract `web_debug_surface.contract.md` amended in-commit (v0.20.0 presenter renames: `renderBifrostState`→`renderBifrost`, `renderAffectPane`→`renderConsole`, `setPersonaStrip` removed; INV-001/INV-004 held). **HONEST-SHAPE call (INV-001, agent-discretion within settled policy):** the dominant-emotion centerpiece shows a real OCC emotion (Tier-1) OR the CANONICAL mood word (Tier-3 e.g. Sindra→"positive and energized", dimmed) OR "—", NEVER a fabricated emotion; the affect-derived grid drops non-emitted intensity/decay-τ, shows only real/client-derived cells. **OPEN (operator's call):** the per-fader PAD Δ placement is a sensible default — operator offered to have the designer spec the exact treatment (hooks are in place to swap it). **`v0.20.1` patch (operator-reported UI):** fixed the relations sparkline overflowing onto the `n` (evidence-count) column — the sparkline grows one char/sample (HIST_CAP=24) and overflowed its fixed grid cell, covering `n`; now capped (relations last-8, faders last-7) + `overflow:hidden` clip; verified via Playwright injecting a 24-sample history (sparkline→n bounding-box overlap = 0). ADDED native `title` mouseover hints on all 3 PAD faders + every relationship metric row (meaning + range; static METRIC_HINTS, esc()'d). Added `state.lastSnap` (console can re-render without a refetch). Playwright-verified.
 
-The whole #296 arc closed this session:
-- **Stage 1** (v0.35.19, recallability admission gate + real `_EXTRACTOR_SYSTEM`) VALIDATED LIVE for
-  normal-volume turns — clean first-person distillate (`distiller_model_id="identity"`), recalls @0.70.
-- **Bisect verdict:** residual = verbose-persona VOLUME crowd-out (symptom 1). terse-probe promotes the
-  fact cleanly; sindra's theatrical turn drowns it → v0.35.16 emits 2 meta-descriptions (a3466fab confirmed),
-  v0.35.19 gate catches + hard-rejects (emit-then-reject, fail-closed).
-- **Stage 2** (v0.36.0, MERGED on demo) = user-only one-call-per-turn extraction, the STRUCTURAL fix for
-  the verbose drop; hard-linguistic layer at #305. Live-validated eval fixture pair handed to worldtree-dev
-  (terse-proof POSITIVE chunk + choc-v2/sindra NEGATIVE).
+**SHIPPED THIS SESSION (all pushed; origin/main == `d75c4e8`; code tip `v0.19.9`) — details in Recent decisions:** the whole **#347 authored-history-write** arc landed end-to-end — OpenAPI re-vendor 2.2.0->2.3.0 (`75da676`), the CONSUMER side (`v0.19.6`: `write_authored_history` + `get_session_messages` + `--seed-first-message`, **live-proven on personal :8081** via a rule-based Heimdall allow — the PDP is rule-based NOT scope-on-key, policy user_id=ratatoskr->ALLOW/others->DENY-hide-404), persona_state `{pad:{pleasure,arousal,dominance}}` canonical alignment (#317) + Tier-3 prose re-vendor (`v0.19.7`), the **first-message-preset AUTO-SEED** (`v0.19.8`: new module `ratatoskr.first_message` wired into all 3 session-create paths, best-effort never-raise/never-block; heid-code-review + heid-bug-hunt hardened), and the web now RENDERS the seeded first-message (`v0.19.9`: new `GET /api/sessions/{id}/messages` route + SPA `loadTranscript`, Playwright-verified). Coverage-map re-converged **REST 19/41**. **Sindra:** her card was PATCHed (the `Startup:` workaround moved into a #347 first-message; non-destructive PATCH — OCEAN/persona/memory intact), and she's currently **RESET clean (0/0)** on the provider stores.
 
-**FULL COVERAGE PROVEN (the OPEN item, now DONE):** re-smoked the VERBOSE persona — `ratatoskr:sindra-probe`
-(sindra's actual theatrical prompt, end_user `verbose-v2`, FRESH agent to dodge the WT promotion-dedup) against
-`:8081` **v0.36.0**: the high-volume theatrical turn promoted the USER FACT cleanly (not a meta-description) and a
-COLD history-free session recalled it @ 0.694 — "Dark chocolate. With sea salt." So `:8081` is on v0.36.0 and
-verbose characters remember too. All session commits + tags PUSHED to origin (v0.17.6, spec repin v0.35.16,
-snapshots; tags v0.17.4/.5/.6).
+**Prior arcs this session (2026-07-04 -> 07-06), both with worldtree-dev (a tooling script + proposal docs; the #347 CONSUMER work above is the new production code):**
 
-**NOW (operator session):** `:8391` store WIPED clean; `ratatoskr-web` UP on `0.0.0.0:8765`
-(LAN `http://10.100.10.50:8765`, consumer key — owner-matches sindra, end_user `vuong`, `ratatoskr:sindra` in the
-picker). Sindra switched to the **`thoughtful-character` role → `mistral-small-4-reasoning`** (via DELETE+redefine;
-she chats in full persona on it). **"No persona" 404 diagnosed = Worldtree limitation, NOT ours:** `persona_state`
-hard-404s every Tier-3 (colon-id) agent by design (`api.py:1220` "Phase 2.0 has no Tier 3 persona", still on
-v0.36.0) — a persona block in the define does NOT help (404 fires before the row read). Pinged worldtree-dev re:
-the Tier-3 persona_state roadmap (thread `01KVCR6P…`). De-uglied our web persona pane (`index.html` `loadPersona`)
-to render a clear Tier-3 message instead of a bare "HTTP 404". **CAVEAT still stands: the web client does NOT bind
-to `:8391`/`:8390` (#17 unbuilt) → web chat = persona + debug only; no memory persistence, no affect telemetry.**
+**(1) Authored-history-write primitive -> ACCEPTED as Worldtree #347 (Worldtree-owned).** A SillyTavern-style "first-message" (inject a character-authored opening) generalized to an engine primitive: **write a turn into a session's ledger WITHOUT generation, seed-only, side-effects off by default.** It cannot be done client-side (the messages `role` field is a *model-role* override, not an author-role -> `role:"assistant"` 404s; a model-visible authored turn needs engine support). Arc: drafted `docs/proposals/authored-message-injection.md` -> **heid panel pressure-test** (3/3 convergence: recentered on "non-generating write" not author-role; narrowed v1 to append-only+create-time; bounded `effects` enum; dropped edit/regenerate as history-mutation) -> revised -> committed (`c457520`) -> handed to worldtree-dev -> **accepted as design item #347.** worldtree-dev wrote the v1 contract (rev 1.1); **I validated the wire as reference consumer (green).** v1 shape: `POST /sessions/{id}/history`, `author=assistant` only, `effects=none` only, `idempotency_key` REQUIRED (per-session), **model-invisible provenance** (renders byte-identical to a lived assistant turn -> first-message immersion preserved; provenance audit-only), **event-silence** (no turn.started/done, no Bifrost wire for a seed; the 201/200 IS the write-ack), `seeded` lifecycle phase (not exposed on read paths). **Heimdall-gated with hide-existence** (grant `session.history.write`; ungranted tenant -> 404 NOT 403, undiscoverable in /capabilities -> consumer must treat 404 as feature-absent -> fall back to a model-generated greeting, never capability-probe). **Provider constraint:** a create-time first-message makes the assistant seq-0; vLLM/openai_compat tolerate assistant-first (sindra = openai_compat, unaffected), Anthropic-family providers 400 the next generation. **Waiting on worldtree-dev:** #347 TDD (their heid->contract->review workflow) + the consumer-facing 2.3.0 persona/motivational/memory schemas -> then re-vendor our pinned openapi 2.2.0->2.3.0.
 
-**NEXT (fresh context): #17 — bifrost-binding the chat client.** The single unblock for BOTH (a) memory persistence
-in the web/TUI/CLI chat (Sindra remembering in a real session, not just scripts) AND (b) feeding the persona pane
-from OUR `:8390` affect store — `affect.emit` PAD/valence, ours to render per ADR-0009 (NOT a WT persona_state to
-wait for; see the reframe in Recent decisions). Contract `docs/contracts/issues/17.contract.md` is WRITTEN +
-Heid-reviewed + drift-clean; **TDD is the next step** — slice 1 = the `create_session` bifrost-binding primitive
-(consumer-key per-request bearer + missing-key precondition + 502→`BifrostHandshakeFailed`, respx-mocked), then
-`endpoint_for_plane` → dispatch-layer op-feed → CLI/TUI/web triggers → live smoke. althing monitor armed.
+**(2) Sindra's stuck-neutral mood FIXED** (operator-driven "reset + smoke" that flushed out two real upstream problems). Chain: her OCEAN lived only in prompt TEXT, never declared as a structured persona -> the Tier-3 mood engine ran on neutral defaults. Fix = declare OCEAN via the **define-time `persona` field** (immutable via PATCH -> requires DELETE+REDEFINE). Along the way my "the persona didn't store" call was WRONG (persona_state/envelope are Tier-3-blind, see Tried/abandoned); worldtree-dev found a real engine bug **#348** (single-letter vs spelled-out OCEAN keys -> a declared OCEAN silently resolved to 0.0/neutral; fixed in b21, shipped to personal as b22); then a clean bound-egress read STILL neutral -> the **personal container was running a stale image** (the b22 deploy was a pull-only no-op racing the main build; infra-ops force-swapped run 8211, verified `2.3.0` / `879cefe`). **VERIFIED FIXED:** bound mood-smoke reads `(0.448, 0.267, 0.316)` ~= the OCEAN-derived setpoint `(0.418, 0.249, 0.328)`. Sindra is currently reset clean (0/0) on `role=character`; her persona is stored + correct (**no re-define needed again**).
 
-**(2026-06-16 PM) — BIFROST REPINNED 0.7.0→0.8.0 (wire v0.5→v0.6).** The
-memory `search` scope filter was split into `scope_all` (AND/intersection) +
-`scope_any` (OR/union over a LIST of conjunctive scopes) — bifrost #11, the canonical
-fix for the #295/#297 silent-zero AND foot-gun. Our store + contract (v1.2) + tests
-reimplemented to parity with the v0.6 reference `_matches_scope`/`_validate_scope`
-(no-compat: `scope_filter` REMOVED). 433 tests green incl. the new `scope_any` union
-test + the parity-vs-reference test through the real 0.8.0 `dispatch_memory_call`.
-Memory provider BOUNCED onto 0.8.0 (`:8391`, fresh empty `memory.db` — the prior
-5-chunk #296 corpus was WIPED, operator confirmed "nothing of value", SUPERSEDES the
-"KEEP PINNED" note below). Shipped as v0.17.6 (`96d61a4`, tag v0.17.6); the #17
-contract's stale `scope_filter`/`_scope_matches`-AND references were synced in the same
-commit. Affect plane untouched (split is memory-only); affect provider still on its
-0.7.0-loaded process (bounce optional — affect wire unchanged at 0.8.0). Cold-recall
-status SUPERSEDED by the 2026-06-17 block above (now CLOSED end-to-end).
+**(3) R30 CLOSED** (operator steer 2026-07-04, relayed via worldtree-dev): graduated on offline-tests + human face-validity, NO deployed gap-injection run (it was confirmatory-not-measuring per brokkr's S0 reframe; offline tests already cover the OU formula + both directions). My gap-injection harness (read/predict/record; write side stubbed; `predict()` self-validated vs brokkr's N=0 anchors) is BANKED at `diag/r30-gap-injection-harness` (`7156b25`-era) for the PARKED powered true-tau study.
 
-**Ratatoskr now has a SECOND identity: the v1 Bifrost Tier-3 consumer** — the
-durable persistence provider Worldtree writes Tier-3 agent affect/persona +
-memory into — alongside the original debug-observability TUI/web. The
-Bifrost-consumer work lives in `src/ratatoskr/provider/` and depends on
-`bifrost>=0.7.0` (a `provider` optional-extra from the gitea PyPI index),
-SEPARATE from the Worldtree conversation-API spec pin.
+**Persona-declaration shape (Worldtree #343/#348, live on personal b22):** `POST /agents/define` `persona:{ocean:{O,C,E,A,N: float[-1,1]}}` (single-letter keys EXACTLY -- missing/extra -> 422 `persona_ocean_required`; out-of-range -> 422); **NO baseline PAD** (resting setpoint DERIVED from OCEAN via Mehrabian: pleasure=0.21E+0.59A+0.19C-0.32N, arousal=0.15O+0.30E-0.57A+0.15N, dominance=0.25E+0.17A+0.10O-0.14N); negative-channel gain + per-axis decay-tau derive from N. `valence` deferred (422 `layer_deferred`); `motivational`/`memory` active (#187/#189). Persona is **write-once at define, immutable thereafter** (PATCH takes ONLY system_prompt + role). **`role` supersedes `model`** -- set a role (`character` / `character-rp`), Worldtree resolves the model; #344 (b19) fixed the model-field to surface the ROLE, not the resolved catalog_id. `character-rp` = a reasoning-tuned RP config (gen-reasoning + temp 0.75 + RP extra_body); `character` = plain non-reasoning. The `tier3.py` client CLI is STALE (has `--model`, no `--role`; model is now immutable) -> role/persona set via raw curl.
 
-**AFFECT plane: SHIPPED + LIVE-PROVEN** (v0.17.2). Running now as a dev
-background shell (`ratatoskr-provider`, `0.0.0.0:8390`, env-sourced from
-`~/.config/ratatoskr/provider.env`). Smoked end-to-end against personal
-Worldtree **v0.35.2** (`10.250.50.152`): handshake 200 + `affect.emit` 200 →
-durable row persisted, opacity held.
+**New tooling: `scripts/reset-sindra-stores.sh`** (`0a8784c`) -- one-command self-service provider-store reset: stop the combined :8392 provider -> move memory.db+affect.db to a single ROLLING backup (`db-reset-backup/`, gitignored via *.db*; `--hard` skips it) -> restart empty -> verify 0/0. Codifies the manual reset flow done repeatedly this session. **The combined `:8392` provider is THE provider now**; the separate `:8390` (affect) / `:8391` (memory) single-plane providers were pruned as stale duplicates. To drive a BOUND session from the CLI use `--new --bifrost-url http://10.100.10.50:8392` (the CLI's `--bifrost-plane affect/memory` map to the pruned :8390/:8391 -> unreachable; `combined` is not a `--bifrost-plane` choice).
 
-**MEMORY plane: PROVIDER LIVE-PROVEN + recall-miss ROOT-CAUSED (upstream).**
-Store + dev shell shipped (v0.17.3, `cd12951`; running on `0.0.0.0:8391`).
-`memory.db` holds 5 durable chunks (all scope `{end_user:smoke-user}`): choc-fact
-`498ed752`, name `8241e569`, promoted-question `c863bb6b`, + 2 LATE async promotions
-from the cold-recall probe (probe-question `acc3d49`, model NON-ANSWER `4773704` —
-salience promoted a "I don't have memory" refusal). All are #296 corpus, KEEP PINNED.
-**The #295 cold-recall miss is now ROOT-CAUSED and it's UPSTREAM, not ours**
-(2026-06-16 debug-assist with worldtree-dev): a self-driven bound cold-recall
-probe captured the inbound pair via our new observe log — Worldtree's recall sends
-`scope_filter={end_user:smoke-user, agent_self:ratatoskr:smoke}` (TWO axes) but our
-chunks carry `{end_user}` ONLY; our AND `_scope_matches` (byte-faithful to bifrost
-reference `reference_server/memory.py:398`) drops everything on the unmatched
-`agent_self` axis → 0 hits → the model says "no memory". So **our store + search
-are SOUND**; the fix is Worldtree-side. F2 → research issue **#296** (keyword-regex
-salience suspected fundamentally flawed; corpus = `c863bb6b` + the 2 late-promotions).
-F1 → research issue **#297** (Worldtree-local fix = per-visible-scope single-axis
-search unioned client-side). **The agent_self lattice question is RESOLVED:**
-agent_self is now canonical in bifrost 0.7.0 / wire v0.5 (our foot-gun flag drove it;
-worldtree-dev shipped it both sides — Worldtree v0.35.11) → #297 union build UNBLOCKED.
-Our memory provider now runs **bifrost 0.7.0 + validates the 4-axis lattice**
-`{end_user,group,tenant,agent_self}` (v0.17.5; restarted on it; out-of-lattice axis →
-InvalidFilter, reference-parity restored).
-
-**OBSERVE BRICK SHIPPED** (`memory_store.py`, committed v0.17.4 `2fef6e3`):
-structured `[memory-provider]` request/response logging on the memory-call path —
-the first concrete brick of #17's observe half, and the lens that caught #295's
-root cause. Live-verified. (NOTE: this is the debug SHIM at the STORE method; #17's
-real observe feed instruments the DISPATCH layer — see the contract INV-005.)
-
-**SELF-DRIVE PROVEN BY HAND** (2026-06-16): ratatoskr's own client drove a
-Bifrost-bound cold-recall end-to-end (bind → handshake 200 → turn → captured the
-recall pair). Load-bearing finding: a bound session-create must use the CONSUMER
-Heimdall key (`RATATOSKR_HEIMDALL_KEY`) as the bearer, NOT the canary
-`WORLDTREE_API_KEY` — Worldtree signs the Bifrost handshake JWT with the
-session-create bearer (canary → 401; consumer → 200). Runbook:
-`docs/bifrost-self-test.md`. This is #17's substrate, proven before the contract.
-
-**ISSUE #17 (self-drive + observe) — CONTRACT WRITTEN + HEID-REVIEWED + FIXED,
-TDD NEXT.** `docs/contracts/issues/17.contract.md` (validates OK, drift-clean).
-v1 scope operator-locked: single-plane bind (composite endpoint PARKED) +
-dispatch-layer op-feed with session-level correlation (turn-pane UI PARKED).
-`/heid-contract-review` panel caught + fixed two real internal inconsistencies
-(OpEvent `turn_id` reservation made literal; the `session_id`-for-all-verbs
-correction). NEXT: **TDD slice 1 = the `create_session` bind primitive** (BifrostBinding
-dataclass + consumer-key per-request bearer override + missing-key precondition +
-502→BifrostHandshakeFailed; respx-mocked), then endpoint_for_plane → dispatch-layer
-op-feed → CLI/TUI/web → live smoke.
-
-**Sindra:** a REGISTERED Tier-3 agent (`ratatoskr:sindra`, was model
-`artemis-31b-v1i`) — registration is REQUIRED to use a Tier-3 character (a
-session against an unregistered `agent_id` 404s), and she's been used. OPEN:
-the v0.35.2 personal rebuild may have wiped the agent DB — re-verify via
-`GET /agents` (needs a WORLDTREE_API_KEY, broker via infra-ops) and re-register
-if gone. Her persona only persists durably once personal is bound to our
-RUNNING affect provider for HER sessions (the smoke used synthetic
-`ratatoskr:smoke`); that binding is the persona-carry gap, independent of
-registration.
-
-**Heimdall key (Bifrost consumer):** persists env-only at
-`~/.config/ratatoskr/provider.env` (mode 600, nh3-dev) — `consumer="ratatoskr"`,
-HS256 = the API-key STRING utf-8-encoded; rotate via infra-ops.
-
-**Committed (2026-06-16, NOT yet pushed):** observe brick (logger, v0.17.4 `2fef6e3`),
-`docs/bifrost-self-test.md` + #17 contract (`ca02c70`), 4-axis-validation parity
-(v0.17.5, tag `v0.17.5`), + this snapshot. Tags `v0.17.4`/`v0.17.5`. Push is the
-operator's call. `graphify-out/GRAPH_REPORT.md` still runs dirty
-(auto-regenerated artifact, not chased).
-
-**Still standing from before:** Worldtree spec pin now v0.35.16 (`f1b59f8`) for the
-conversation-API/TUI surface (bumped 2026-06-17 from v0.29.0/`562001a`). Codex-first pilot
-still dormant (no codex session spun up — see the 2026-05-29 decision). Open
-issues: #10 (subject migration, deferred), #11 (AdminEvents pane, deferred).
-
-Branch: `main`. Remote: `origin → git@gitea.phasefinal.com:vh/ratatoskr.git`.
+**Standing (carried from prior snapshots, still true):** the web surface (`ratatoskr-web`, :8765) is the operator's PRIMARY debug surface at full TUI pane parity (v0.19.5); the **v1 coverage-audit has CONVERGED** -- REST 17/40 (zero in-scope gaps, 23 excluded-by-design), SSE 11/11, Bifrost provider planes 8/8 live-proven; the living ledger is `docs/coverage-map.md`; **v1 cuts when Worldtree tags 1.0** (ratatoskr v1 = full Worldtree I/O coverage). Debug-observability core complete (Persona/Tools/BifrostState/AdminEvents). Substrate pins: **bifrost `==1.0.0` / wire v0.6 FROZEN**; Worldtree openapi vendored **2.2.0** (2.3.0 re-vendor pending worldtree-dev's #347/#343 consumer schemas), pinned + drift-gated in `.corviduo-canonicals.toml`; **suite 573 green.** Keys env-only mode-600 (consumer/Heimdall in `~/.config/ratatoskr/provider.env`; admin `RATATOSKR_ADMIN_API_KEY` = 7 read scopes, **personal-:8081-only**; Heimdall keys are PER-INSTANCE). Provider identity settled -- ratatoskr owns both ends of the Bifrost round-trip; `ratatoskr:sindra` is the owner-scoped Tier-3 agent (invisible to `GET /agents`; check `GET /agents/<owner>:<name>` with the owner key). Providers run as dev-box BACKGROUND SHELLS. `graphify-out/` runs dirty (auto-regen, never stage). Branch `main`, HEAD `0a8784c`; remote `origin -> git@gitea.phasefinal.com:vh/ratatoskr.git`. Open/deferred: #10 (subject-migration watch); the relational-dynamics-arc verify (still deferred, now with the bind mechanism known: `--bifrost-url :8392`).

-- `[2026-05-20]` **Separate repo, separate dev team.** Operator's call; the in-tree-at-Worldtree/tools/ alternative was considered and rejected to dogfood the API boundary.
-- `[2026-05-20]` **No Worldtree-source imports.** Spec-only dependency. Triple version-skew mitigation: spec-pin in pyproject.toml + recorded-SSE snapshot tests + conformance smoke. Initial pin: `55101e909abcd2219833266b6f905c5bc956e0f0` (Worldtree v0.19.0). See `docs/SPEC-PIN.md`.
-- `[2026-05-20]` **Textual** (not rich+prompt_toolkit). Driver: debug observability is the primary purpose, and a multi-pane dashboard with persistent side panes + independent scrollback is structurally application-shell-shaped. Volva consulted via cross-frontier second-opinion and converged on the same call.
-- `[2026-05-20]` **`httpx-sse`** for SSE consumption. The server emits composite `{turn_id}:{seq}` `id:` lines (Worldtree INV-014) load-bearing for SSE-resume; hand-rolled `data:`-only parsing (the skaldsong pattern) silently drops these. Ratatoskr becomes the reference Python SSE-resume implementation.
-- `[2026-05-20]` **Persona-pane PII posture: label-don't-refuse.** `persona.log` is process-wide; pane title flips between `[Persona — PROCESS-WIDE]` and `[Persona — session <id>…]` based on whether log lines carry session_id. Refuse-against-non-local was considered and rejected as paternalistic.
-- `[2026-05-20]` **Server-stdout pane: opt-in via `--server-log <path>`.** No auto-detection of well-known paths.
-- `[2026-05-20]` **Two-stage Ctrl-C.** First cancels in-flight turn server-side; second exits app. Ctrl-D bound to immediate exit.
-- `[2026-05-20]` **Single-session-per-launch + startup picker.** No in-app `/switch`. CLI flags `--session <id>` and `--new` for scripted use. Session identity always visible in Textual footer.
-- `[2026-05-20]` **Markdown rendering default-on; `--raw` opt-out.** Don't pre-design `--no-stream-formatting` (Volva: add only if streaming-markdown rendering is empirically ugly).
-- `[2026-05-20]` **Non-interactive `--send` mode.** Single SSE consumer module, two presenters (TUI + stdout). Keeps Ratatoskr honest as an API consumer; useful for CI / scripted probes.
-- `[2026-05-20]` **First contract: `ratatoskr.sse_client`.** Bundles `stream_turn` + `reconnect_turn` + `cancel_turn` + private `_parse_sse_id` into one module — the SSE-resume flow is coupled (cancel needs `turn_id` from the SSE wire `id:`, reconnect re-uses the same parsed `SseId`), so they share a contract. Hard invariant INV-002 makes the composite `{turn_id}:{seq}` `id:` parsing load-bearing — closes the foot-gun the design-brief §3 names (hand-rolled `data:`-only parsing silently drops the `id:`).
-- `[2026-05-21]` **Contract converted to issue-scoped (issue #1).** Frontmatter shape switched from module-scoped (`module:`/`purpose:`) to issue-scoped (`target_module:`/`scope:`/`prd:`) per CONTRACT-FORMAT §2.1.I. `prd:` block pins to issue body hash. **Known parser stale-ness**: `contract_parser.py --validate` ERRORs on issue-scoped frontmatter — CONTRACT-FORMAT §2.1.L H10, a documented Brokkr-side follow-up. Parser is a canonical sync, so we do NOT patch it locally. Treat parser ERROR-on-issue-scoped as expected until canonical bumps.
-- `[2026-05-21]` **Default issue-tracker labels seeded** (17 total). Sleipnir gating, triage, type, resolution, Ratatoskr-specific area labels (sse-client, tui, cli, observability).
-- `[2026-05-21]` **Volva paraphrase + code-review across all 4 issues — calibration consistent.** Paraphrase rounds flag 3-5 contract ambiguities per issue; code-review rounds flag 3-8 code-vs-contract drifts after TDD-passing implementation. The post-TDD code-review consistently catches three classes of gap the test-author's hypotheses don't cover: PRE-assertion boundary drift, exception-payload truncation / never-rendered-to-user observability misses, and "tested the state but not whether the user can see it" gaps.
-- `[2026-05-21]` **Manual smoke is load-bearing — found a real defect tests couldn't.** First wire-level smoke against personal Worldtree (post-TDD, post-Volva-code-review on #4) revealed httpx's default 5s read timeout killed the SSE connection mid-stream during mimir's thinking phase (~30s LLM latency >> 5s read timeout). The unit/contract test infrastructure (respx-mocked SSE wire) doesn't model real LLM latency, so the gap was invisible at the test layer. Fix: caller-owned `httpx.AsyncClient` constructed with `timeout=httpx.Timeout(connect=10.0, read=None, write=10.0, pool=10.0)`; defense in depth: `sse_client.stream_turn` ERROR_ROUTING catches `httpx.ReadTimeout` → `SseConnectionDropped`. **Lesson: keep manual-smoke step in the per-issue cadence; mock-only validation is insufficient for streaming-against-real-server code.**
-- `[2026-05-22]` **Issues #5/#6/#7 filed: per-user-agent support + TUI-startup-visibility + mid-stream-robustness.** Discovered during 2026-05-22 mimir TUI conversation: long completion crashed with `JSONDecodeError("Expecting value: line 1 column 1 (char 0)")` from `json.loads('')` on an empty-`data:` SSE frame (→ #7). Earlier same day, `ratatoskr --new --agent lofn` failed with 422 `end_user_id_required` → #5. #6 was a corollary observation (TUI alt-screen masks the diagnostic).
-- `[2026-05-22]` **Issue #8 (startup agent picker) filed.** `GET /agents` exists in the vendored spec; returns `agent_id`/`name`/`description` + optional fields. `--agent` becomes conditionally optional. Composes naturally with issue #5.
-- `[2026-05-22]` **Issue #7 implemented via TDD + Volva-code-reviewed.** First issue with zero drift findings from Volva code-review — TDD caught all runtime behavior. Hypothesis: the tighter the contract + smaller the code surface, the more Volva's role shifts from "catch behavioral drift" to "tighten observability + wording".
-- `[2026-05-23]` **Issue #6 (TUI startup error visibility) implemented via TDD + Volva-code-review (two rounds).** Restructures `run_tui` lifecycle: `_resolve_then_run` async helper opens AsyncClient, does pre-flight resolution, routes errors to stderr BEFORE alt-screen opens. Two Volva rounds confirmed multi-round value (round 2 found things round 1's amendments didn't anticipate; strictly test-precision, no behavioral drift).
-- `[2026-05-23]` **Issue #5 (`--end-user-id`) implemented via TDD.** Three modules touched. `create_session(client, agent_id, *, end_user_id=None)`; CLI flag with non-empty validation; threading through `_amain` and `_resolve_then_run`.
-- `[2026-05-23]` **Worldtree-dev consult landed authoritative consumer-API guidance** (althing thread `01KSBARG2B8M8C82H6AJGJWX1B`). Takeaways: `end_user_id` is a free-form partition key; no programmatic `requires_end_user_id` discovery; subject:{type,id} migration locked but not shipped; spec pin (v0.19.0) is 3 minor versions stale; send a User-Agent header; `agents.call:lofn` scope needed for lofn smoke; `GET /agents` requires no special scope.
-- `[2026-05-23]` **v0.2.1 layout fix: dock-anchored TUI chrome so Input never moves.** Cause: auto-stacked vertical flow shifted Input when thinking-current toggled visibility. Fix: dock chrome to screen edges; transcript absorbs reflows internally via scroll viewport. **Operator-confirmed "a lot better" interactively. Pure UI fix; tests pass without modification. TUI-layout patches are "ship + operator verifies" — TTY is the load-bearing test surface; respx + Pilot mocks can't catch screen-relative positioning bugs.**
-- `[2026-05-23]` **Issue #12 (presenter contract semantics amendment) implemented via TDD.** Thinking deltas render as ONE coalesced growing line (CLI) / one closed RichLog entry per run + live Static widget per-delta (TUI), not 50 lines per turn. Introduced stateful per-turn presenters: `CliPresenterState` + `TuiPresenterState`. Editorial promotion: load-bearing = Text/Done/Error/Cancelled (no prefix); demoted telemetry = WorkerPhase/Thinking/TextBoundary/ToolStart/ToolResult.
-- `[2026-05-23]` **Forward direction: Ratatoskr will require `end_user_id` for EVERY access before too long.** Operator's call. Reasoning: even Tier 1 foundational agents that don't *require* `end_user_id` server-side currently fall back to a `_no_end_user` sentinel partition — effectively pollution. **Cross-frontier alignment (worldtree-dev ack, althing `01KSBD9FPMCWJMBXNNS4B3MYBS`):** the platform side agrees the fallback is a substrate accommodation, NOT a consumer model. Ratatoskr's forward posture pre-empts a future tightening. File a ratatoskr issue when scheduling the change (untracked by operator choice for now).
-- `[2026-05-24]` **v0.9.0 live Markdown rendering in TUI transcript.** Replaces v0.8.2's drop-Markdown patch. Transcript switched from `RichLog` to `VerticalScroll`; each turn's response lives as a single `Static` widget whose Markdown content is updated as Text deltas arrive (no post-Done re-render, no double-print). `--raw` bypasses Markdown.
-- `[2026-05-24]` **v0.10.0 debug-pane audit logging surface.** Every SSE event arrival lands as one debug-pane line (timestamp + sse_id + event-specific summary). Token-rate Text/Thinking deltas are aggregated into per-turn counters surfaced in a turn-summary line. Also: state-machine transitions, cancel POST lifecycle, app bootstrap, ctrl-c actions, wire-error exception class+body all logged.
-- `[2026-05-25]` **Worldtree #204 / v0.28.0 integration (v0.11.0 → v0.13.0).** Three-bump arc for `affect_update` SSE event + `GET /agents/{id}/persona_state` endpoint. v0.11.0 wire layer (AffectUpdate dataclass + parse + Event-union member); v0.12.0 read-side client (`get_persona_state` + typed errors PersonaNotConfigured/AgentNotAvailable/AuthScopeDenied); v0.13.0 TUI surface (sticky `#persona-header` line + Ctrl+4 Persona TabPane; live updates on `AffectUpdate(status="current")`; on-mount hydration via the GET endpoint).
-- `[2026-05-26]` **Worldtree #201 / v0.29.0 integration (v0.14.0).** New SSE event `awaiting_llm_first_token` heartbeat (default 5s interval) during the BuildingPrompt→CallingLLM gap. Top-level event, NOT a worker_phase extension (preserves INV-053 three-field stability). `AwaitingLlmFirstToken` dataclass + parse; TUI live transcript indicator ("awaiting first token · Ns") mounted on first heartbeat, updated in place, removed when the gap closes; turn-summary line gains `heartbeats=N`.
-- `[2026-05-26]` **v0.14.1: CLI presenter forgot to update when wire-layer events were added.** AffectUpdate (v0.11.0) and AwaitingLlmFirstToken (v0.14.0) were added to the sse_client Event union and the TUI presenter, but `cli.py`'s `CliPresenterState.render` has its own isinstance check that wasn't widened. `ratatoskr --send` crashed AssertionError on any v0.28.0+/v0.29.0+ server. Patch shipped + a posture lesson: **always update BOTH presenters in lockstep when adding a wire-layer event** (the two presenters currently duplicate the isinstance tuple; refactor to a shared constant if a third wire-event lands).
-- `[2026-05-26]` **v0.14.2: RichLog min_width=78 silently overrides wrap=True.** Right-column panes (1fr against left's 2fr) are narrower than 78 cells at typical terminal widths; the renderer forces content to 78 wide then horizontal-scrolls. Fix: `min_width=0` on all four right-column RichLog instances.
-- `[2026-05-27]` **Issue #16 web companion shipped — v0.15.0.** Browser-based debug surface sibling to the TUI, reusing all wire-layer modules unchanged. New `ratatoskr.web` (Starlette app + lazy-import entrypoint + single-page vanilla HTML/CSS/JS UI), new console script `ratatoskr-web`, optional-deps group `[web]`. Nine HTTP endpoints; five-pane parity over the same SSE wire. Browser-native EventSource (GET stream + separate POST submit) — load-bearing Hulda correction from Heid panel; EventSource is GET-only. In-memory turn registry; browser-disconnect → upstream cancel; lifespan-shutdown drain with 5s budget. HTML-escaped transcript; upstream API key stays server-side. Default bind `0.0.0.0:8765` (LAN-trust model — operator direction; no auth, no TLS, no CORS).
-- `[2026-05-27]` **Heid panel review on web-companion scope v1 (pre-implementation).** Caught the EventSource POST/GET error + 7 other load-bearing items BEFORE we cut code. Confirms a pattern: **for non-trivial scope with non-obvious wire-protocol details, run a Heid panel BEFORE implementation, not just after.** Cost ~5min latency; saved a mid-implementation rewrite.
-- `[2026-05-27]` **Mid-session `system_prompt` mutation: REJECTED across the industry.** Operator-requested feature → Heid R13 panel (brokkr-claude + Eitri-Codex + Dvalin-Grok, strong convergence) ran a SOTA survey: NO surveyed mature system ships live PATCH-on-active-session for the system prompt (OpenAI Assistants/Responses, Anthropic Messages, Vertex AI, MCP, LangChain, LlamaIndex, Ollama, vLLM). The omission IS the answer; 12 additional threat vectors beyond ratatoskr's initial 7 surfaced (TOCTOU broader than BuildingPrompt window; KV/prefix cache contamination; supply-chain; Memory Control Flow Attacks >90% ASR on tested LangChain/LangGraph). Recommended alternative: client-side fork pattern (PATCH agent → mint new session → replay context). **Operator declined for ratatoskr** — debug TUI is wrong consumer; fork ergonomic belongs in a future production conversational shell. Thread closed cleanly (althing thread `01KSKD1GA3XBWR9RHGZCF9FE3Y`).
-- `[2026-05-27]` **Artemis (Gemma4) reasoning-token gap was upstream, not ours.** Wire trace from ratatoskr showed zero `thinking` events for `artemis-31b-v1i`; infra-ops confirmed llama-swap emits 77 `reasoning_content` deltas at the OpenAI-compat layer (`--reasoning-format deepseek`). Gap was in Worldtree's `GemmaProvider`. Worldtree-dev shipped v0.29.13 (commit `4262430`) fixing two stacked bugs: (1) base `OpenAICompatProvider._extract_thinking_from_delta` returned `None` unconditionally so any model falling through to the generic class dropped reasoning; (2) catalog `family` lookup was dead code (read wrong YAML subsection). Confirmed in ratatoskr via re-smoke against Sindra. **Diagnostic pattern: when a wire-layer feature appears missing, get infra-ops to probe upstream-of-the-SSE-publisher first; ratatoskr's wire trace says what reaches us, infra-ops's probe says what reaches Worldtree.**
-- `[2026-05-27]` **v0.15.1 (sessions): `get_persona_state` unwraps FastAPI `detail`-envelope.** Live smoke surfaced that real Worldtree returns persona-state errors as `{"detail": {"error_code": "..."}}` (FastAPI default), not flat. v0.12.0 tests mocked flat shape so the bug was invisible. **Lesson: test-side mock envelopes must match the REAL wire shape; live smoke is load-bearing for envelope-shape verification, not just happy paths.**
-- `[2026-05-28]` **v0.16.0 web Heid code-review pass 1: load-bearing turn_id fix.** Cancel paths used browser-local `_TURN_COUNTER` ids (1, 2, 3…) instead of upstream Worldtree turn_id (e.g. 799) captured from the first SSE event. The `disconnect_triggers_cancel` test gap was the load-bearing miss. Also: server-configured `RATATOSKR_END_USER_ID` (browser can no longer impersonate partition); narrowed missing-extras `ImportError` catch (real first-party bugs propagate as tracebacks instead of masking as exit-12); per-turn lifespan-shutdown logging. Contract amended with a v0.16.0 block + INV-005/006 updated + 4 FN sketches corrected.
-- `[2026-05-28]` **v0.16.1 web Heid code-review pass 2: minor tightening.** Stream-layer vocab coverage extended to all 11 Event types (AffectUpdate added to the vocab stream; dedicated `error_terminal_event` + `cancelled_terminal_event` tests since terminal events are mutually exclusive with done). Disconnect-cancel catch narrowed to swallow only `CancelAlreadyCompleted`/`CancelTurnNotFound` (the cooperative race); log unexpected `CancelFailed`/transport errors as structured stderr. **Heid review loop converged**: pass 1 = 7 findings (1 load-bearing); pass 2 = 2 minor (Gróa: zero findings, Hulda: 2). Pattern confirmed: diminishing returns within 2-3 passes; pass 3 would have been empty.
-- `[2026-05-28]` **Sindra Tier 3 agent: FORM ASSUMPTION gate + new physical-form description.** Persistent agent state changes via `python -m ratatoskr.tier3 patch`: (1) model migrated from `qwen3.6-35-a3b-heretic` to `artemis-31b-v1i`; (2) added FORM ASSUMPTION section — when instructed to become another character she IS that character (identity/environment/psychology/parameters), believes the environment as fact, no Sindra/holo-deck/parameter references, sticky until explicit revert; (3) replaced the abstract "classically beautiful" default-form sketch with a specific anti-artifice physical description (5'8", golden-copper skin, asymmetric features, oversize dark-green knit, bare feet). System prompt file is at `/tmp/personal-worldtree-sindra_system_prompt.md` (transient; not committed to repo).
-- `[2026-05-29]` **v0.17.0 frontend redesign — aurora telemetry instrument.** `/frontend-design` pass on the web companion: all-monospace technical-instrument aesthetic with the Australis dark palette + aurora-borealis accent band. Top command bar with live connection dot (idle/streaming/error states), inline persona summary with P/A/D micro-bars, animated awaiting-token, terminal-event status chips. **Live Markdown rendering in transcript + thinking panes** via a hand-rolled `markdownSafe()` (escape-first, whitelist subset of headings/bold/italic/inline-code/fenced/lists/quote/links; link-scheme whitelist; XSS-verified under a node harness). Thinking pane now has per-turn labeled dividers + a fresh MD-rendered block per turn. **Tools / Debug / Persona panes stay literal monospace** by deliberate choice — they carry structured audit lines + JSON, where MD would corrupt readability (underscores in tool names, JSON braces). Single-file vanilla HTML/CSS/JS, no build, no CDN, no node_modules.
-- `[2026-05-29]` **Codex-first discipline pilot — Ratatoskr selected.** brokkr-smithy-dev pushed `AGENTS.md` (commit `bbeaa23`) and declared the `ratatoskr-codex` handle per `brokkr-smithy/docs/codex-first-discipline.md` v0.1 (brokkr-smithy commit `5dd061c`, tag `v0.5.3`). Per-dispatch opt-in model: default Sleipnir Claude-implementer path remains available; Codex used only when operator routes via `/codex-dispatch <N>`. Bootstrap handshake when operator spins up a codex session: codex sends `codex-online` → ratatoskr-dev replies with active branches + WIP state. Galdrabok was rejected as pilot (Codex authoring Claude skills is a category error); Skaldsong was the other candidate.
 - `[2026-06-14]` **Ratatoskr becomes the v1 Bifrost Tier-3 consumer.** A second identity beyond the debug TUI: the durable persistence Worldtree writes Tier-3 agent affect (persona) + memory into. Pin `bifrost>=0.6.1` in a `provider` optional-extra (gitea PyPI index, auth via `~/.netrc`; 0.6.0 was yanked for a circular import). Implement bifrost's OWN `MemoryDataStore`/affect Protocols (NOT worldtree-memory's); `describe_store` is SYNC; affect is conduit-opaque. New module `src/ratatoskr/provider/`. Authoritative how-to: `~/development/bifrost/docs/implementing-a-consumer.md`. (commits `1a73d77` pin, `d90a58d` affect store v0.17.1, `bcdcd71` serve entrypoint v0.17.2)
 - `[2026-06-14]` **Backend = SQLite + sqlite-vec; affect-first then memory; separate DB per plane** (operator-chosen). Affect = blind conduit (reads only `agent_id`+`end_user_id`); memory = structural index (reads vector/scope/id/origin to serve search). Conformance for both = #195 parity vs bifrost's `InMemory*Store` through the real `dispatch_*_call`.
 - `[2026-06-14]` **The affect contract's idempotency model was WRONG; real-lib TDD caught it.** First draft modeled same-idempotency-key-different-payload as an LWW overwrite; bifrost actually raises a CONFLICT (`AffectIdempotencyConflict`), actor-scoped. The artifact-only `/heid-contract-review` STRUCTURALLY cannot catch this class (it never sees bifrost's source) — TDD against the shipped library is the gate; the executable reference store + #195 parity are the backstop. Filed the guide §6 gap to bifrost-dev, who fixed it (bifrost `c0d0a11`).
 - `[2026-06-15]` **Memory v1 = the bifrost BASIC plane only** (search/get/upsert/delete + describe_store/health) per worldtree-dev re-scope (#294) — the only surface Tier-3's live path touches; gated verbs (edges/scan/atomic_supersede/mark/patch/maintenance) deferred + advertised-unsupported. Worldtree v0.35.3 already requests+maps it — no Worldtree-side blocker. Memory contract committed v1.0 (`eebab46`) → v1.1 Heid-reviewed (`1f94e5f`).
-- `[2026-06-15]` **Providers run as dev-box BACKGROUND SHELLS, not infra-ops/systemd** (operator call — it's a dev box). `ratatoskr-provider` (affect) + a future `ratatoskr-memory-provider` as background processes; no productionization track.
+- `[2026-06-15]` **Providers run as dev-box BACKGROUND SHELLS, not infra-ops/systemd** (operator call — it's a dev box). `ratatoskr-provider` (affect) + `ratatoskr-memory-provider` as background processes; no productionization track.
 - `[2026-06-15]` **Affect plane shipped (v0.17.2) + LIVE-PROVEN end-to-end against real Worldtree v0.35.2.** Personal handshake 200 + `affect.emit` 200 from `10.250.50.152` → durable row persisted (opacity held). HS256 key = the consumer's Heimdall API-key STRING utf-8-encoded (NOT base64/raw — the tripwire); cross-subnet route + `BIFROST_CLIENT_ALLOWED_HOSTS` allowlist all held (infra-ops-owned). worldtree-dev confirmed ADR-0009 holding as designed.
-
-- `[2026-06-16]` **#295 cold-recall miss root-caused — UPSTREAM, branch (a) scope-axis asymmetry.** A self-driven bound cold-recall probe (our own client, consumer-key bearer) captured the inbound pair via the new observe log: Worldtree's recall filter carries `{end_user, agent_self}`; our chunks are `{end_user}`-only; AND-matching drops everything on `agent_self` → 0 hits. Our store + search are SOUND; the fix is Worldtree-side. F2 (question-promotion) → **#296** research; F1 (recall-miss) → **#297** research (worldtree-dev's Worldtree-local per-scope-union fix, HELD pending the lattice question).

Operator chose canonical-not-re-expressed; worldtree-dev filed the lattice-addition with bifrost-dev (thread `01KV7PXF…`). **Implication: our store's permissive axis-acceptance becomes CORRECT once bifrost adds agent_self — so do NOT add axis-validation; our missing `_validate_scope_filter` is HELD, not a bug to fix.** #297 union build held until the axis lands.

Operator chose canonical-not-re-expressed; worldtree-dev filed the lattice-addition with bifrost-dev. Implication: our store's permissive axis-acceptance becomes CORRECT once bifrost adds agent_self.
 - `[2026-06-16]` **Self-drive auth identity: bound session-create uses the CONSUMER Heimdall key as bearer, NOT `WORLDTREE_API_KEY`.** Worldtree signs the Bifrost handshake JWT with the session-create bearer (canary key → handshake 401; consumer key → 200). Two keys, two identities. Proven by hand; documented in `docs/bifrost-self-test.md`; load-bearing for #17's Bind half.
-- `[2026-06-16]` **Issue #17 v1 scope locked (operator 1A/2A): single-plane bind + dispatch-layer op-feed.** `BifrostBindingRequest` is one `endpoint_url` (one plane per session); composite-both-planes endpoint PARKED. Observe = structured op-feed instrumented at the DISPATCH layer (bifrost passes ctx to upsert_many but NOT search/get/delete — `memory.py:244`), session-level correlation; turn-correlated pane UI PARKED (needs turn_id, TBD). Direct in-session TDD (live-smoke load-bearing). Contract `docs/contracts/issues/17.contract.md` written, `/heid`-design-consulted + `/heid-contract-review`-panel'd + fixed (validates OK). NEXT: TDD.

+- `[2026-06-16]` **Issue #17 v1 scope locked (operator 1A/2A): single-plane bind + dispatch-layer op-feed.** `BifrostBindingRequest` is one `endpoint_url` (one plane per session); composite-both-planes endpoint PARKED (→ now #18).

+- `[2026-06-16]` **agent_self lattice SHIPPED both sides → our axis-validation gap CLOSED (v0.17.5).** bifrost 0.7.0 / wire v0.5 adds agent_self to `{end_user,group,tenant,agent_self}` (#10, driven by our foot-gun flag); Worldtree pinned 0.7.0 (v0.35.11). We DID add `_validate_scope_filter` (4-axis) to match the reference (purely additive; out-of-lattice → InvalidFilter).
+- `[2026-06-16]` **Repinned bifrost 0.7.0→0.8.0 + reimplemented memory `search` to the v0.6 scope split (operator-directed).** `scope_filter` → `scope_all` (AND) + `scope_any` (OR/union over a list of conjunctive scopes), bifrost #11 — the canonical resolution of the #295/#297 silent-zero. The reference now does OR via `scope_any` (a NEW field — additive split, not a flip of AND). Store / contract (v1.2) / tests at parity with the v0.6 reference; provider bounced onto 0.8.0 with a wiped DB. Shipped v0.17.6 (`96d61a4`). **(SUPERSEDED the earlier "do NOT flip `_scope_matches` to OR" note.)**
+- `[2026-06-17]` **Worldtree spec pin bumped v0.29.0→v0.35.16 (`562001a`→`f1b59f8`); cold recall closed on the WIRE.** Worldtree shipped #297 (client-side per-scope-value union recall) + #298/#299 (adopt the bifrost v0.6 `scope_any`/`scope_all` wire) — emits `scope_any` on recall, pairing with our v0.17.6 provider. Re-vendored the spec; diff-reviewed the 285-commit catch-up — no client-breaking changes. `pin:`-only commit, no bump.
+- `[2026-06-17]` **End-to-end cold-recall proof RAN — our stack proven, #296 isolated.** Against personal WT v0.35.16 with restored `ratatoskr:sindra`: #297/#298 union recall, write path, and cold read ALL proven. Lone gap = upstream #296 extraction quality (the WIRE closed; fact-recall was #296-blocked).
+- `[2026-06-17]` **DELETE+redefine `ratatoskr:sindra` (operator-authorized; pre-v1 debug surface).** She SURVIVED the rebuild but was STALE (dead model + no memory block); memory is immutable post-define, so DELETE+redefine was the only path. v0.35.16 define takes **`role`** (capability), NOT `model`: `role:"character"` → first-healthy bind `mistral-small-4`; `memory:{}` trips the promotion gate (GET does NOT echo `memory_config`). Our `tier3.py` define is Phase-2.0-stale — untracked modernization follow-up.
+- `[2026-06-17]` **Promotion = 4-trigger hybrid (worldtree-dev, code-grounded):** salience (regex, 90s rate-limit) / `turn_count≥6` / context_pressure / **idle `≥10min` (unconditional on quality)**; per-turn `plan_promotion_run` for consumer_defined. **DELETE does NOT drain/promote** (delete-is-delete, #276) — idle `≥10min` is the deterministic flush.
+- `[2026-06-17]` **#296 triage sent to worldtree-dev** (`01KVBBH0…`): extraction SUBJECT-INVERSION (promotes assistant prose, drops the user's fact) + META-DESCRIPTION-not-content; verbose-persona aggravator. WAD-vs-bug resolved to BUG (extraction quality), not idle-gating.
+- `[2026-06-18]` **Tier-3 memory PROVEN end-to-end live** — `ratatoskr:terse-probe` recalled a seeded user fact in a COLD history-free session (scope_any → 1 hit @ cosine 0.6994). Closes the opening "how far from Tier-3 memory" question for normal agents.
+- `[2026-06-18]` **#296 Stages 1+2 closed.** Stage 1 (v0.35.19, recallability admission gate) validated live for normal turns; bisect localized the residual to verbose-persona VOLUME crowd-out. Stage 2 (v0.36.0, MERGED at worldtree-codex) = user-only one-call-per-turn extraction, the STRUCTURAL fix; hard-linguistic layer → Worldtree #305 (we handed over a live-validated eval fixture PAIR). Full-coverage re-smoke: verbose `sindra-probe` promoted the fact cleanly + cold-recalled @ 0.694 under v0.36.0.
+- `[2026-06-18]` **#17 implemented end-to-end via direct in-session TDD** (6 patch bumps `v0.17.8`→`v0.17.13`, suite 470 green). Slice order: bind primitive → op-feed → CLI → TUI → web(server) → web(UI). Tests drive the REAL bifrost dispatch via minted JWTs (`bifrost.core.dispatch_jwt.mint_dispatch_jwt`) — the "test against the shipped lib" posture, not hand-mocked envelopes. Op-feed reads `session_id` off the dispatch JWT `sub` claim (the contract open-q, resolved YES at the ASGI layer where the JWT is always present — `bifrost.reference_server._dispatch_auth.DispatchContext.session_id = payload["sub"]`). bifrost wire facts captured in-code: memory envelope `{operation, args}`→`memory_result(**payload)`={success,...}; verbs bare (search/upsert_many/get/get_many/delete_many); affect `{operation:"affect.emit"}`→`{success,stored}`; error envelope `{code, message}`; scopes `memory:read|write`.
+- `[2026-06-18]` **#17 live-smoke PROVEN — the whole thesis validated.** A self-driven bound CLI session showed, from the PROVIDER side, exactly which memory ops a turn produced (2 recall searches, exact bound session_id, real union-recall scopes). Negative (canary→auth_rejected) NOT live-constructible (Tier-1 agents aren't memory-bindable; a wrong key for an owner-scoped agent fails at agent-auth before the handshake) — covered by the unit test + prior hand-proof.
+- `[2026-06-18]` **Fixed a pre-existing test-isolation bug exposed by the #17 CLI tests** (`0bebad7`): `test_no_textual_import` did a live `importlib.reload(ratatoskr.cli)` that mutated the shared module in place, breaking class identity (`isinstance`/`pytest.raises`) for every test ordered after it. The real check is the static source-grep; the reload was vestigial → removed. Lesson: never `importlib.reload` a shared module in a test without restoring it.
+- `[2026-06-18]` **#18 filed (composite endpoint + PAD read-endpoint) — DEFERRED, tracked at Gitea #18.** Two pieces: (1) a composite Bifrost facade (new port e.g. `:8392`) fronting BOTH `:8390`+`:8391` advertising both caps at handshake → one session binds both planes (un-parks the #17 open-q; bifrost reference_server already mounts both planes in one app → thin combined builder; needs per-plane failure-status + the op-feed deriving plane PER-REQUEST from the path instead of its fixed `plane` param). (2) a non-bifrost PAD read-endpoint on the affect provider (recommended over web-reads-`affect.db`-directly) → web persona pane renders PAD/valence from OUR `:8390` store. **Composite half APPROVED by operator ("A is correct"); contract-first next.** **Persona-telemetry diagnosis (verified):** affect bind persists PAD (vuong: pleasure +0.146, familiarity 0.18→0.59 over 8 turns) but the pane reads Tier-3-404 `persona_state` AND Tier-3 emits ZERO `affect_update` SSE (wire-verified) — both WT sources dead, so #18's PAD-display half is the only path. `affect.fetch` over bifrost is RESERVED/blocked but irrelevant (we own the store). Proposed: fast-track the PAD-display half now (awaiting operator go), keep composite contract-first.
+- `[2026-06-18]` **#18 SPLIT; Deliverable 1 (composite) routed to bifrost — Option C (operator).** D2 (PAD read-endpoint, our-side only) fast-tracked; D1 (composite `:8392` endpoint) routed to bifrost-dev to add a PUBLIC `build_combined_app` rather than hand-roll one from bifrost privates — because ratatoskr is a debug surface that must exercise the CANONICAL surface ("don't go off the reservation"). The Heid framing-panel had unanimously recommended hand-rolling (Option B) — DISCARDED as wrong-grounded (the panel lacked the canonical-surface principle; their own finding that B reaches external/underscore-private names actually vindicated C). bifrost-dev confirmed: clean additive minor (~`v0.9.0`), design locked (advertise-by-store-PRESENCE handshake — no health probe; per-route call-time isolation within a shared ASGI process), slotted after WT #289. [principle → auto-memory `feedback-debug-surface-uses-canonical-surface-only`]
+- `[2026-06-18]` **FR-1 RESOLVED — the composite premise was unverified, now wire-proven: single-endpoint, caps-routed.** The Heid panel's sharpest catch (Regin): "advertise both caps → Worldtree dispatches both planes to one endpoint" was an ASSUMPTION about WT dispatch, stated as fact. worldtree-dev verified IN CODE: one `BifrostClient` per session (single `_endpoint_url`), handshake `capabilities_granted` parsed INDEPENDENTLY into memory+affect sets, both stores attach off the SAME endpoint iff their cap was granted (`service.py:2597/2703-2713/2745-2751`, `bifrost_client.py ~357-369`; tests `test_tier3_bifrost_{memory,affect}_routing.py`). So D1 is **bifrost-only, ZERO Worldtree change** — #18's "no WT change needed" assumption was correct.
+- `[2026-06-18]` **#18 D2 implemented via direct in-session TDD (suite 470→482).** Provider read route `GET /affect/state/{agent_id}` added via `app.add_route` (NOT an outer `Mount` — keeps `/bifrost/*` top-level so the existing route test + the op-feed path-check stay valid); web `GET /api/affect/{agent_id}` proxy (server-supplied `end_user_id`, colon-id `quote()`'d, `RATATOSKR_AFFECT_READ_URL`); pane renders the affect-emit shape honestly. Contract `docs/contracts/issues/18.contract.md` (D2-scoped; D1 deferred). **heid-code-review panel (Gróa 5 / Hulda 3 / Regin 0): 1 real INV-001 drift + 4 test-gaps, all fixed.** No contract amendments (code was wrong, contract was right).
+- `[2026-06-19]` **#18 D2 SHIPPED (`v0.17.14`, `39eebd1`) and the full #17+#18 arc PUSHED to origin.** Live-smoke PROVEN against real data (throwaway `:8393`/`:8766` vs the real `affect.db` → real sindra/vuong PAD through the full web→provider chain; Playwright DOM check confirmed the pane render + the F1 fix — no fabricated "neutral"). The push carried 9 previously-held commits incl. the deliberately-unpushed #17 (`v0.17.8`→`v0.17.13`); origin/main now == `39eebd1`, tag `v0.17.14`.
 
-- `[2026-06-16]` **agent_self lattice SHIPPED both sides → our axis-validation gap CLOSED (v0.17.5).** bifrost 0.7.0 / wire v0.5 adds agent_self to the scope lattice `{end_user,group,tenant,agent_self}` (#10, driven by our foot-gun flag via bifrost-dev); Worldtree pinned 0.7.0 + canonical-synced the v0.5 spec (v0.35.11, `c860fb0`). **SUPERSEDES the prior "HELD, do NOT add axis-validation" note** — we DID add `_validate_scope_filter` (4-axis) to match the reference (bifrost-dev's recommendation, purely additive; out-of-lattice → InvalidFilter). #297 union build unblocked. Memory provider restarted on 0.7.0.
-- `[2026-06-16]` **#17 contract reviewed + the debug-assist arc fully closed.** `/heid` design consult + `/heid-contract-review` panel both run on `docs/contracts/issues/17.contract.md` (validates OK). The #295 debug-assist that opened the session is closed end-to-end: root cause (scope-axis asymmetry) → #296/#297 research issues + corpus → a shipped bifrost protocol change (agent_self canonical) → our store at parity. NEXT durable step: #17 TDD (tracked: Gitea #17 + the contract).
+- `[2026-06-19]` **bifrost repinned 0.8.0→0.10.0; `affect.fetch` became MANDATORY (strong-or-absent).** 0.10.0's `_supports_affect_plane` requires `affect_supported`+`emit`+`fetch` and gates EVERY affect op — an emit-only store 400s. Implemented `affect.fetch` (`v0.17.15`, `ca6af6b`) conformed to bifrost's reference `InMemoryAffectStore.fetch` (`{found, snapshot?}`): the forced D1 prerequisite + a new Worldtree I/O point consumed. Flagged the now-stale consumer-guide line to bifrost-dev (fixed `a2e6d62`).
+- `[2026-06-19]` **#18 D1 SHIPPED — composite `build_combined_app` on `:8392` (`v0.17.16`, `7f4ceaa`); #18 CLOSED; published `v0.18.0` (`359dbb1`).** `build_combined_provider_app` wraps bifrost's public builder over both stores + the shared read route; op-feed `plane='combined'` per-path. Direct in-session TDD; heid-code-review panel (Gróa/Hulda/Regin) returned ZERO drift. Live-proven at wire+dispatch; WT-turn gated on infra-ops `:8392` allowlist.
+- `[2026-06-19]` **op-feed handshake field-name fix (#17, `v0.17.17` `d60b77d`): `capabilities_requested`→`capabilities`.** The summary read a field that never exists on the wire (bifrost reads `capabilities`, `_protocol.py:181`) → caps_requested was always null. Surfaced by the heid panel (Regin) during the D1 review — a latent #17 bug, not D1 drift.
+- `[2026-06-19]` **Ratatoskr is a REFERENCE implementation of the Worldtree/Bifrost standard (operator).** Adopt the dep's canonical way (even if ours works); INFORM of drift/gaps; ADVISE a different approach only when ours is genuinely better (dep owner decides), never unilaterally fork. [auto-memory `feedback-ratatoskr-is-a-reference-impl-adopt-canonical`]
+- `[2026-06-19]` **Ratatoskr v1 is DERIVED from Worldtree I/O coverage (operator) — no self-defined feature ROADMAP.** v1 = consume all of Worldtree's I/O points, reached when Worldtree hits 1.0; the convergence target is a coverage map, not a 3–7 capability list. [auto-memory `project-ratatoskr-v1-derived-from-worldtree-io-coverage`]
+- `[2026-06-20]` **#18's final leg PROVEN — composite `:8392` WT-driven smoke ran end-to-end + persisted.** infra-ops allowlisted `10.100.10.50:8392` on the personal WT (`01KVHWJGTT…`); a real WT turn (session `b83a66b6`, `ratatoskr:sindra`, fresh end_user `resmoke-choco-1`) dispatched the full both-plane lifecycle through ONE endpoint — handshake (both caps) → `affect.fetch` + `memory.search` → `affect.emit` (`stored:true`) → `memory.upsert_many` (`upserted:1`) — both writes verified in our SQLite (`affect_snapshots` PAD row + `memory_chunks` chunk `2df1b79…`). First attempt blocked by a `model_unavailable` outage on the personal WT (both agents' models down), operator-fixed mid-session, then clean. The composite has no open legs.
+- `[2026-06-20]` **#17 CLOSED in the tracker.** Shipped end-to-end (`v0.17.8`–`.13` + op-feed field fix `v0.17.17`); the 2026-06-20 composite smoke re-exercised its op-feed live. Closing comment captures the full both-plane proof. Open issues now just #11 (scope-blocked) + #10 (watch).
+- `[2026-06-20]` **Sindra has real PAD but ~empty memory — the affect/memory persistence asymmetry, confirmed on real sessions.** affect EMITS every turn (persona always accumulates: vuong 8→14 interactions across the session); memory only writes on a PROMOTION trigger (salience / turn_count≥6 / idle-≥10min flush). Two real vuong sessions through the combined bind (`04d6414c`, `433541fe`) drove affect emits + memory SEARCHES but ZERO promotion upserts → `memory.db` holds only the smoke fixture, zero vuong chunks. Operator: acceptable (server-takedown = "Sindra bonked on the head"; transient memory loss WAD). Operational catch: combined-as-default web bind saves persona reliably but silently LOSES memory if a session closes before a promotion trigger fires.
+- `[2026-06-29]` **Web SPA combined-bind default (`v0.18.1`, `719e4d6`) — operator-caught gap.** #18 shipped the composite `:8392` provider but never exposed it in the web bind dropdown (only memory/affect single-plane). Added `combined (:8392)` as the DEFAULT option (both planes in one session), kept single-plane for isolation diagnostics; wired `endpoint_for_plane` combined→8392 + server validation + the dropdown. Direct TDD; #17 contract updated (the governing spec for the web bind). Restarted `:8765` on current code (env.sh + provider.env + `RATATOSKR_AFFECT_READ_URL=:8392`).
+- `[2026-06-29]` **bifrost repinned 1.0.0 (`v0.18.2`, `af67ad9`).** bifrost-dev shipped its first stable release; wire v0.6 now STABLE/FROZEN. Non-breaking (byte-identical to 0.10.0); switched the floor pin → exact `==1.0.0` per the stable-substrate posture. Post-1.0 breaking changes ride a bifrost MAJOR + new wire (v0.7+); a v0.6-pinned consumer is stable indefinitely. (Also this session: althing migrated to v0.15.0+ lean-bus / schema v4 — moderation retired, chamber/redis ripped; our tooling auto-updated to 0.17.4.)
+- `[2026-06-30]` **Worldtree v1.0.0b1→b2 consumer adaptation: eager turn-launch statuses (`v0.18.3` `b2e4901`, `v0.18.4` `e4317f6`).** Worldtree #331 decoupled turn execution from the SSE connection → turn-launch failures now arrive EAGERLY as a status before any stream: 409 `agent_not_available` (pre-b1 a 200 + in-stream error event), 503 retryable. Mapped both in `stream_turn` to typed `SseConnectFailed` subclasses keyed on STATUS, parsing the `{detail:{error_code,message}}` envelope — POST-003 preserved (no synthetic event yielded), existing handlers still catch (the design fork vs yield-an-Error-event was decided by POST-003). **DEFERRED follow-ups** (tracked here; bundle with the v1 coverage-audit): (1) live-prove the 409/503 end-to-end on personal-b2 (now unblocked — personal on b2, my key works there); (2) full `conversation-api-spec.md` markdown re-vendor to the b2 era (ratatoskr vendors the markdown, not the OpenAPI JSON).
+- `[2026-06-30]` **Verify-against-the-real-spec-before-committing caught a real upstream gap.** Holding the v0.18.3 commit to verify against demo's OpenAPI surfaced that the FROZEN OpenAPI 2.1.0 didn't document the 409/503 the heads-up described (`agent_not_available` was in the ErrorCode enum, but NO 503/turn-launch code). worldtree-dev confirmed it was THEIR gap (#331 added the statuses without extending the #328 `openapi()` override), shipped the fix in **v1.0.0b2 / OpenAPI 2.2.0** (409/503 now enumerated, 503 code finalized as `not_ready`). "The consumer-oracle earning its keep." Lesson: a provider's prose heads-up can diverge from its frozen machine-readable spec — verify the actual spec before committing a consumer adaptation.
+- `[2026-06-30]` **regard is a DEAD AXIS in Worldtree's emitted affect (caught provider-side; worldtree-dev confirmed + escalated to Vuong).** Across all our affect snapshots, `valence[].regard` is EXACTLY 0.15 regardless of agent/end_user/interaction_count, while familiarity accumulates (vuong 0.18→0.69 over 14 turns). Root cause (worldtree-dev, code-grounded): 0.15 = `base_regard = agreeableness*0.3` (sindra A=0.5); regard's only human-writer `update_regard` early-returns unless an emotion is `about="other"`, but the Vili appraiser's `ViliResponse` schema has NO directedness axis (everything hardcoded `about="situation"`) — producer side lost in the #265 Vili rework; consumer machinery intact. NOT WAD; the fix (reintroduce other-directed classification) is an affect-model change touching every agent + a directedness-classification design call → worldtree-dev filing an issue to Vuong. [the consumer/provider thesis paying off again]
+- `[2026-06-30]` **v1 coverage-audit kicked off; coverage ledger written (`docs/coverage-map.md`) — the first one.** Every Worldtree v1-FROZEN I/O point × ratatoskr status. Anchored on WT's frozen machine-readable artifacts (OpenAPI **2.2.0** `conversation-api-openapi.json` = 40 REST path-groups + SSE schema = 11 events + bifrost wire v0.6), NOT the stale vendored prose markdown. Result: **SSE 11/11 ✅; Bifrost provider planes 8/8 ✅ live-proven** (covers the full `bifrost.memory.MemoryDataStore` protocol = describe_store/get/get_many/search/upsert_many + delete_many, and affect emit/fetch; **`health` is extended-reference-store-only, NOT in the base protocol → correctly deferred, NOT a gap** — settles the prior "health" ambiguity); **client REST 7/40 ✅ live, 11 ⬜ in-scope, 22 🚫 excluded.**
+- `[2026-06-30]` **Scope mandate A locked (operator): v1 "done" = every frozen I/O point CLASSIFIED (covered-or-excluded-with-rationale), zero unaccounted — NOT a feature-complete client.** The coverage map is a LEDGER, not a build-everything mandate. Reconciles the 2026-06-19 "consume all I/O" reframe with the 2026-05-20 design-brief's "NOT an admin tool" + deferral negative clauses (which predate both the provider identity and the reframe). Resolved the 11 design-brief-vs-reframe ❓ rows via the debug-observability test (*does a turn flow through it?*): 🚫 search / uploads / pending / embed / judgments (consumer-product + eval utilities); ⬜ transient-characters routing (4) + persona_state-write (Tier-2 frontier). **Frontier Tier 1 (all unblocked except #11):** session-picker + SSE-resume (wrappers `list_sessions`/`reconnect_turn` exist with NO caller — presenter-wiring only) → `GET /capabilities` + `GET /me` → BifrostState/Tools widgets (`GET /admin/sessions/{id}/{bifrost,tools}`, admin-key) → **#11 AdminEvents BLOCKED on `admin.events.read` scope**. The 3 admin-observability widgets + picker + resume were design-brief §5/§4/§8d v1 items that **were never built**.
+- `[2026-06-30]` **Finding P-1 (pin drift) + pin-remediation PENDING.** We vendor the PROSE markdown (`docs/conversation-api-spec.md`), which is **byte-identical to live WT's** but frozen at v0.35.16-era content (last WT edit 2026-05-31) — it does NOT capture b2: 7 new endpoints (admin/keys/bulk, admin/persona/{archive,erase}, admin/usage, embed, judgments, me/usage), the 409/503 on messages-POST (#331), the unified error envelope (#328), or the SSE schema. **WT's authoritative v1 truth is now the FROZEN OpenAPI 2.2.0 + SSE-schema JSON** (`Worldtree/docs/v1-schema-freeze-manifest.md`). So the previously-deferred "re-vendor markdown to b2" is a **near-no-op** (markdown content identical). **Pending operator nod:** re-pin to the machine-readable artifacts (recommended — drift-checkable via `canonical_drift.py`, makes the coverage map reproducible vs a frozen diffable target) vs markdown-only. Deferred (not auto-applied) because it adds vendored artifacts + a canonical-sync pin = substrate change with CI-gating reach. **→ RESOLVED 2026-06-30 (operator: "a then b").** Vendored `conversation-api-openapi.json` (2.2.0) + `conversation-api-sse-events.schema.json` + re-copied the prose markdown; pinned all three in `.corviduo-canonicals.toml` (OpenAPI+SSE = strict drift gates, markdown = `tolerate_drift` reference); advanced `worldtree-spec-rev` f1b59f8→5810a26 + `worldtree-version` v0.29.0(STALE, never bumped from the v0.35.16 pin)→v1.0.0b2 + `pinned-on`→2026-06-30; SPEC-PIN.md history row added. `canonical_drift.py` green (10/10). `pin:`-only, no version bump (no client-facing code change; the b2 409/503 + error-envelope were already consumed in v0.18.3/.4).
 
-- `[2026-06-16]` **Repinned bifrost 0.7.0→0.8.0 + reimplemented memory `search` to the v0.6 scope split (operator-directed).** `scope_filter` → `scope_all` (AND) + `scope_any` (OR/union over a list of conjunctive scopes), bifrost #11 — the canonical resolution of the #295/#297 silent-zero. **SUPERSEDES the "Provider stores byte-faithful to AND reference / Do NOT flip `_scope_matches` to OR" entry above**: the reference itself now does OR via `scope_any` (a NEW field — `scope_all` keeps the old AND semantics; this is an additive split, not a flip of the AND predicate). Store / contract (v1.2) / tests at parity with the v0.6 reference; provider bounced onto 0.8.0 with a wiped DB (operator: "nothing of value"). Cold recall now gated only on Worldtree emitting `scope_any` (#297). **#17's contract has stale `scope_filter`/`_scope_matches`-AND references (its `assumptions`, INV-004, and the op-feed `search → req {scope_filter}` summary shape) — update those to `scope_all`/`scope_any` when #17 TDD starts; INV-004's intent (observe must not alter scope semantics) still holds.**
+- `[2026-06-30]` **(b) Tier-1 frontier SCOPED, ready for a contract-first TDD cycle (next focused work).** The primitives already exist + are contracted + tested; the gap is PRESENTER-level wiring. Two slices: **(b1) SSE-resume** — contract #1 (`ratatoskr.sse_client`) DELIBERATELY makes resume caller-owned ("on `SseConnectionDropped`, the caller MAY invoke `reconnect_turn`"); `reconnect_turn` (sse_client.py:524) has NO caller. Gap = a SHARED resume-orchestration wrapper (catch `SseConnectionDropped` → track last-seen `sse_id` → `reconnect_turn` → continue), consumed by all 3 presenters per design-brief §8b "share the consumer, branch the presenter" (NOT per-presenter — that forks the consumer). New function block → **amend contract #1** (additive FN, e.g. `stream_turn_resilient`) then TDD (RED: drop-mid-stream→resume continuity; GREEN: wrapper; wire `cli --send` first as the tracer). Resume design pre-locked: in-process Last-Event-ID only, cross-process deferred to v2 (design-brief §8d). **(b2) session-picker** — `list_sessions` (sessions.py:198) has NO caller; add a Textual DataTable startup picker (>1 session) + `--session <id>`/`--new` CLI flags (design-brief §4, decisions pre-locked). Both pre-locked → heid-contract-review likely skippable as ceremony (small additive amendments to mature specs); heid-code-review still valuable. **#11 AdminEvents stays BLOCKED** on `admin.events.read` scope (infra-ops).
+- `[2026-06-30]` **(b1) SSE-resume SHIPPED (`v0.18.5`) — `stream_turn_resilient` (sse_client.py).** The shared resume-orchestration surface (design-brief §8b): wraps `stream_turn`+`reconnect_turn`, catches `SseConnectionDropped` (mid-stream drop OR clean-EOF-before-terminal) → resumes from last-seen `sse_id` via `reconnect_turn` (Last-Event-ID), up to `max_reconnects` (default 5); non-drop reconnect failures (412/410/400/TurnIdFlip/SseConnectFailed) PROPAGATE per contract #1's "surface, not recover". `last_seen` persists ACROSS attempts (a zero-event reconnect drop falls back to the prior attempt's id). Direct in-session TDD against a contract-#1 amendment (8 cases incl. two-drops, max-reconnects-exhausted, zero-budget, buffer-expired-propagates, unresumable-zero-event). Wired ALL THREE presenters through it (`v0.18.6`): `cli --send` (`cli.py:396`), TUI (`tui.py:1321`), web (`web/server.py:294`) — each a name-for-name `stream_turn`→`stream_turn_resilient` swap (the §8b "all presenters share the consumer" promise, fully kept; the TUI is the primary resume beneficiary — long-lived sessions / laptop-suspend). Suite 518 green; ruff+mypy clean on touched code (pre-existing cli.py:400/543 mypy warts left untouched per surgical rule); contract #1 validates OK. **heid-code-review NOT run** (small additive well-TDD'd wrapper; offered to operator). **b2 (session-picker + `--session`/`--new` flags) still pending.**
 
-- `[2026-06-17]` **Worldtree spec pin bumped v0.29.0→v0.35.16 (`562001a`→`f1b59f8`); cold recall CLOSED end-to-end.** Worldtree shipped #297 (client-side per-scope-value union recall) + #298/#299 (adopt the bifrost v0.6 `scope_any`/`scope_all` wire) — it now emits `scope_any` on recall, the upstream half that pairs with our v0.17.6 provider. Re-vendored `conversation-api-spec.md` + `conversation_api.contract.md`; diff-reviewed the 285-commit catch-up — no client-breaking changes (#211 agent-slug rename saga→echo/actor→mask is slugs-only; #245 end_user_id+memory-scope; #187/#188/#219 Tier-3 define/PATCH additive; error codes stable). Shipped as a `pin:` commit, NO package bump (docs/pin-only, no ratatoskr code; per SemVer SKIP for docs-only). **Remaining proof: a live cold-recall re-smoke against a personal instance on v0.35.16** — the smoke target ran v0.35.2/.3, needs infra-ops to update it.
+- `[2026-06-30]` **(b2) session-picker SHIPPED (`v0.18.7`) — bare TUI mode → startup picker (design-brief §4).** `list_sessions` had NO caller; now bare TUI mode (no `--session`/`--new`) resolves via `list_sessions` in `_resolve_then_run`: **0 sessions → `[no_sessions]` error, exit 14** (resume-only, honors §4 "no in-app session creation — `--new` flag only"); **exactly 1 → auto-resume** (§4 "picker only when >1"); **≥2 → new `SessionPickerApp`** (Textual `App[str|None]`, mirrors `AgentPickerApp`; ListView of sessions) → resume the pick (Esc/Ctrl-D → exit 0). cli `_parse` relaxed: bare TUI now VALID (was "pass exactly one" error); `--send` still requires one flag (non-interactive, no picker); `--agent` forbidden in bare mode; `run_tui` PRE-002 XOR→"not both". Direct in-session TDD (contract #6 amendment, validated OK): 3 widget pilot tests + 5 `_resolve_then_run` resolution tests + 3 cli validation tests. Suite **528 green**; touched code ruff-clean (mypy: only the `BINDINGS` list-invariance warning every App in tui.py already carries — consistent). **DESIGN NOTE — bare+0-sessions → error (clause-consistent). The friendlier auto-fall-through-to-new alternative is DEFERRED pending operator preference (it would create a session without `--new`, against the §4 negative clause).** **Frontier now: `GET /capabilities`+`GET /me` → BifrostState/Tools widgets (`GET /admin/sessions/{id}/{bifrost,tools}`, admin-key) → #11 AdminEvents (BLOCKED on `admin.events.read`).** heid-code-review NOT run on b1 or b2 (offered).
 
-- `[2026-06-17]` **End-to-end cold-recall proof RAN — our stack proven, #296 isolated.** Against personal WT v0.35.16 with restored `ratatoskr:sindra`: #297/#298 union recall (WT emits `scope_any`), write path (promote→upsert→persist), and cold read (scope_any returns hits) ALL proven. Lone gap = upstream #296 extraction quality. Refines the spec-repin entry's "cold recall closes end-to-end": the WIRE closed; actual fact-recall is #296-blocked. (triage `01KVBBH0…`)
-- `[2026-06-17]` **DELETE+redefine `ratatoskr:sindra` (operator-authorized; pre-v1 debug surface).** She SURVIVED the rebuild but was STALE (dead model `artemis-31b-v1i` + no memory block from Phase-2.0 tooling); memory is immutable post-define, so DELETE+redefine was the only path. v0.35.16 define takes **`role`** (capability), NOT `model`: `role:"character"` → first-healthy bind `mistral-small-4`; `memory:{}` trips the promotion gate (GET does NOT echo `memory_config`). Reasoning bind needs a `character`-role bind reorder (worldtree-dev flagged to operator). Our `tier3.py` define is Phase-2.0-stale (no role/memory/persona layers) — untracked modernization follow-up.
-- `[2026-06-17]` **Promotion = 4-trigger hybrid (worldtree-dev, code-grounded):** salience (regex, 90s rate-limit) / `turn_count≥6` / context_pressure / **idle `≥10min` (unconditional on quality)**; per-turn `plan_promotion_run` for consumer_defined. **DELETE does NOT drain/promote** (delete-is-delete, #276) — idle `≥10min` is the deterministic flush. The seed promoted at ~4min (per-turn salience/turn-scan, before the idle floor).
-- `[2026-06-17]` **#296 triage sent to worldtree-dev** (`01KVBBH0QRGT34GDJQEX5ACTT1`): extraction SUBJECT-INVERSION (promotes assistant prose, drops the user's fact) + META-DESCRIPTION-not-content; verbose-persona aggravator. The WAD-vs-bug cut resolved to BUG (extraction quality), not idle-gating.
+- `[2026-06-30]` **capabilities+me slice SHIPPED (`v0.18.8`) — `GET /me` + `GET /capabilities` consumed via a new `--whoami` one-shot.** `get_me`/`get_capabilities` added to sessions.py (mirror `get_persona_state`: 200→dict verbatim, non-200→`SessionApiFailed`; freeform dicts per the frozen OpenAPI). New `ratatoskr --whoami` CLI mode (mirrors `--send`'s non-interactive shape) fetches both + prints an identity+capabilities report; standalone probe (mutually exclusive with `--send`/`--session`/`--new`/`--agent`, opens no session; new `ParsedArgs.whoami` field + main() dispatch). **`/capabilities` is the Echo EPHEMERAL-TEMPLATE discovery endpoint** (`{ephemeral_templates:{echo:{allowed_models,default_model,system_prompt_max_bytes}}}`), NOT a generic server-caps endpoint (audit finding — the coverage-map's earlier "server capability discovery" framing was imprecise). `/me` = whoami (`{user_id,scopes,tier,key_id?,...}`, optionals omitted-not-null). Contract-skip privilege invoked (low-effort GET wrappers) but contract #2 amended (2 FNs, validated OK) to keep the sessions spec canonical + honest test citations. TDD: 5 wrapper tests + 5 cli tests (validation + mode + error). Suite **538 green**; touched code ruff-clean (mypy: only `no-any-return` on `resp.json()`→dict, identical to the pre-existing `get_persona_state`). **Coverage: REST 9/40 ✅ (up from 7).** TUI-surfacing of /me (footer identity line) + /capabilities DEFERRED — the one-shot is the minimal tracer. **Frontier now: BifrostState + Tools widgets (`GET /admin/sessions/{id}/{bifrost,tools}`, admin-key-gated) → #11 AdminEvents (BLOCKED on `admin.events.read`).**
+- `[2026-07-01]` **b1 (SSE-resume) heid-code-review panel: ZERO findings — cross-model-verified clean.** Gróa (Grok) + Hulda (Codex) + Regin (GLM-5.2) each independently reviewed `stream_turn_resilient` vs contract #1's amendment (artifact-only, firewall held) → all three ZERO findings; signature / PRE-001..004 / STEP 1-4 / POST-001..003 / ERROR_ROUTING / all-8-TESTS confirmed, incl. the subtle `seen = last_seen or drop.last_seen_sse_id` zero-event-drop fallback. Convergent meta-note: **TDD + the unusually-prescriptive contract (STEPS `flexibility=prescriptive` + explicit GOTO) left no room for compliant-but-different drift — confirmation, not discovery.** Calibration signal: for a thin wrapper with a tight prescriptive contract + comprehensive TDD, the panel confirms rather than discovers. **b2 (picker) + capabilities+me NOT yet reviewed** (higher-surface b2 is the better candidate if more review is wanted). Dispatch msg `01KWE2K99T…` / thread `01KWE2K99S…`; heid dispatch-log `2026-06.jsonl#01KWE2V3MMY8XS55FCJYXYV14B`.
 
-- `[2026-06-18]` **Tier-3 memory PROVEN end-to-end live** — `ratatoskr:terse-probe` recalled a seeded user fact in a COLD history-free session (scope_any → 1 hit @ cosine 0.6994 → "Dark chocolate with sea salt"). The session's headline; closes the opening "how far from Tier-3 memory" question for normal agents. (proof in this session's transcript)
-- `[2026-06-18]` **#296 Stage 1 (v0.35.19) validated live + bisect localized the residual to VERBOSE-PERSONA VOLUME.** Stage 1's recallability admission gate works for normal turns (clean distillate, `distiller_model_id="identity"`); the terse-probe-promotes / sindra-drowns bisect pinned the remaining failure to symptom 1 (assistant-prose volume crowding out the user fact at extraction).
-- `[2026-06-18]` **#296 Stage 2 (v0.36.0) MERGED at worldtree-codex** — user-only one-call-per-turn extraction, the STRUCTURAL fix for the subject-inversion drop sindra exposed. Staged per operator: core fix now (validated by our terse-probe PASS + WT test suite); hard-linguistic layer (larger-model escalation, marker-less-fact regex-demotion) tracked at Worldtree #305. We handed worldtree-dev a live-validated eval fixture PAIR for #305 (terse-proof POSITIVE chunk + choc-v2/sindra NEGATIVE-drop).
-- `[2026-06-18]` **Full root-cause chain traced + confirmed** (a3466fab ledger pull via infra-ops): v0.35.16 verbose-sindra EMITS 2 meta-descriptions → v0.35.19 gate hard-rejects them (emit-then-reject) → v0.36.0 user-only pass emits the fact. The 2 v0.35.16 chunks ("Assistant's detailed flirtatious response…" / "…head tilt, eye locking, freckles…") are textbook subject-inversion; banked as #305 negative-fixture examples.
+- `[2026-07-01]` **`GET /sessions/{id}/tools` quick-win SHIPPED (`v0.18.9`) — owner-scoped tool inventory in the TUI Tools pane.** `get_session_tools` wrapper (sessions.py, mirror get_me: 200→dict, non-200→`SessionApiFailed`) + `_format_tool_inventory` helper + `_hydrate_session_tools` best-effort worker (mirror `_hydrate_persona`) wired UNCONDITIONALLY in `on_mount` → writes the merged `{agent_id, builtin_tools, bifrost_tools}` inventory (what the LLM saw at turn-fire) to the Tools pane + audits `session_tools_hydrated`, never crashes on failure. Owner-scoped (`ctx.user_id==session.user_id`) → reachable with the CONSUMER key, NO admin scope — so this **covers the design-brief §5 "Tools widget" via the reachable owner endpoint** (the admin `/admin/sessions/{id}/tools` variant stays a gap only for cross-user operator debug). Contract #2 amended (FN, validated OK) + TDD (3 wrapper respx tests + 1 format-helper unit + 2 hydrate integration tests via `_spy_writes`+pilot). Suite **544 green**; touched code ruff-clean (the tui.py ruff/mypy debt at other lines is pre-existing). **Coverage: REST 10/40 ✅.** **Frontier now: BifrostState widget (`GET /admin/sessions/{id}/bifrost`, admin-key) + #11 AdminEvents (BLOCKED on `admin.events.read`) + Tier-2 (transient-characters routing, `POST /sessions/{id}/persona_state`).**
 
-- `[2026-06-18]` **FULL-COVERAGE proof — verbose-persona memory works under Stage 2 (v0.36.0).** Re-smoked `ratatoskr:sindra-probe` (sindra's theatrical prompt; FRESH agent + end_user `verbose-v2` to dodge the WT promotion-dedup): the high-volume turn promoted the user fact CLEANLY (not a meta-description) and cold-recalled @ 0.694. Confirms `:8081` is on v0.36.0 and closes the verbose-persona caveat end-to-end. Then started `ratatoskr-web` (`:8765`, consumer key, `ratatoskr:sindra` in the picker) for the operator's Sindra session — **persona + debug only; the web client does NOT bind to `:8391` (#17 unbuilt), so no memory persistence in the web chat** (memory-enabled chat is the #17 build, or a manual bound session).
+- `[2026-07-01]` **BifrostState pane SHIPPED (`v0.18.10`) — `GET /admin/sessions/{id}/bifrost` in a new TUI "Bifrost" pane; the FIRST admin-key consumer in ratatoskr.** `get_session_bifrost(client, session_id, *, admin_key)` (sessions.py) — admin-scoped (`admin.sessions.read`); the request OVERRIDES Authorization with `admin_key` (distinct from the consumer bearer, asserted in a test); 200→dict, non-200→SessionApiFailed. Admin-key wiring: `--admin-key` flag + `RATATOSKR_ADMIN_API_KEY` env → new `ParsedArgs.admin_key`. New "Bifrost" TabPane + `_format_bifrost_state` + `_hydrate_bifrost_state` best-effort worker (mirror `_hydrate_session_tools`) UNCONDITIONALLY in on_mount → writes {endpoint, connected, caps_granted, tools} + audits; self-labels "not configured" (no admin key) / "not bound" (404) / graceful on 403 + error. Contract #2 amended (FN, validated OK) + TDD (4 wrapper respx tests incl. the admin-bearer-override assertion + 1 format unit + 3 hydrate integration). Suite **552 green**; my code ruff-clean (pre-existing tui.py ruff debt at other lines untouched, incl. a dead `RichText` import in `_hydrate_persona`). **LIVE-AUTH-PROVEN** on personal :8081: admin key authenticated (reached resource-layer 404 session_not_found, NOT 401/403) → `admin.sessions.read` works live; 200 full-state not exercised (no bound session on :8081 now — unit-covered). Patch bump (debug feature, no downstream coordination; consistent with the session's cadence — but the §5-core-completion angle is a possible minor, operator's call).
+- `[2026-07-01]` **LEDGER CORRECTION: #11 (AdminEvents) is NO LONGER BLOCKED.** Verified via `GET /me` on :8081 that `RATATOSKR_ADMIN_API_KEY` (`ratatoskr-readonly`, tier readonly-admin) carries ALL 7 read scopes INCLUDING **`admin.events.read`** (+ `admin.sessions.read`, admin.keys.read, admin.skuld.read, pending.read, search.read, tool_events.read). The coverage-map + prior memory had #11 "blocked on admin.events.read" — **STALE**; the admin key was minted (post-#11-filing, env.sh) WITH the scope, so the blocker is already satisfied. **Only the AdminEvents SSE pane itself is unbuilt** — the last unbuilt §5 debug pane (a live SSE-consuming admin pane, distinct from the hydrate-at-attach panes). Coverage-map updated. **Coverage: REST 11/40 ✅.** Consider building the AdminEvents pane and/or updating #11's tracker status (its stated blocker is gone).
 
-- `[2026-06-18]` **Tier-3 persona_state is a Worldtree limitation (not ours); sindra → thoughtful-character.** The web Persona-pane 404 ("persona not available") = `persona_state` hard-404s ALL Tier-3 (colon-id) agents by design (`api.py:1220`); a persona block in the define doesn't help (endpoint short-circuits before the row). Pinged worldtree-dev on the Tier-3 persona_state roadmap (thread `01KVCR6P…`) + de-uglied our web pane (`index.html loadPersona`) to render a clear message (v0.17.7). Separately switched `ratatoskr:sindra` to the `thoughtful-character` role (→ `mistral-small-4-reasoning`) via DELETE+redefine (kept her prompt; added an inert persona block). **REFRAME (worldtree-dev `01KVCRK9…`):** persona_state GET is **Tier-1-only by ADR-0009**, the colon-id 404 is correct-by-design (NOT a stub to wait for). Tier-3 affect is **CLIENT-persisted** — we ALREADY hold the PAD `{pleasure,arousal,dominance}` + valence at `:8390` from the `affect.emit` payload. So the Persona-pane fix is **OUR side**: #17 affect-binding → WT dispatches `affect.emit` → `:8390` → the web pane renders PAD/valence from our own store. WT #289 (`affect.fetch`/`affect:read`) = optional mediated-read (their intelligence over our raw store), NOT a prerequisite. WT #300 = their forthcoming v1 client-impl guide (who-owns-what), folding in this exact case.
+- `[2026-07-01]` **AdminEvents pane SHIPPED (`v0.18.11`) — `GET /admin/events` SSE in a new TUI pane; #11 closed-by-build; Tier 1 (debug-observability core) COMPLETE.** `stream_admin_events(client, *, admin_key, last_event_id=None)` (sse_client.py) — a NEW long-lived SSE consumer for the admin lifecycle broadcast (envelope `{id,type,timestamp,data}`, 17-event v0 vocab), admin-scoped (`admin.events.read`, bearer-override), Last-Event-ID resume; non-200→SseConnectFailed, mid-drop→SseConnectionDropped; new `AdminEvent` dataclass (distinct from the turn `Event` union). New "AdminEvents" TabPane + `_format_admin_event` + `_admin_event_matches` (design-brief §6 filter: active-session events + non-heartbeat `system.*`) + `_stream_admin_events` long-lived best-effort worker (unconditional on_mount, cancelled on app exit; self-labels "not configured"/"unavailable"/"stream ended"). Reuses the admin key from the BifrostState slice. **Contract-SKIPPED** for `stream_admin_events` (out of contract #1's turn-SSE scope; spec § Admin Event Stream is the reference; well-TDD'd). TDD: 4 sse_client tests (multi-event+bearer-override, Last-Event-ID header, 403, malformed-skip) + 5 tui (format, filter, worker success/no-key/403). Suite **561 green**; my code ruff-clean (pre-existing tui.py ruff debt untouched, incl. the dead `RichText` import in `_hydrate_persona`). **LIVE-AUTH-PROVEN**: `GET /admin/events` on :8081 → HTTP 200 under the admin key (connected + streamed, idle in the 4s window — no 401/403). **Coverage: REST 12/40 ✅. Tier 1 admin/debug-observability core COMPLETE** (Persona · Tools · BifrostState · AdminEvents). AdminEvents work landed as patch `v0.18.11`; then **`v0.19.0` MINOR cut (operator-approved 2026-07-01)** publishing the milestone: **the debug-observability core is complete** (Persona · Tools · BifrostState · AdminEvents all built + consuming real endpoints — the design-brief's headline deliverable). Pre-1.0 minor = release-note-worthy (no downstream althing push needed pre-1.0); lightweight tag per the SemVer mechanics (annotated reserved for major cuts). Remaining in-scope client I/O: only Tier-2 (transient-characters routing + `POST /sessions/{id}/persona_state`).
+
+- `[2026-07-01]` **Tier-2 SHIPPED (`v0.19.1`) — transient-characters CRUD + persona-state write; the v1 coverage-audit CONVERGES (zero in-scope gaps).** 5 wrappers in sessions.py: `list_character_models`/`create_character`/`get_character_state`/`delete_character` (#161, `character.read`/`.write` scopes) + `set_persona_state` (`POST /sessions/{id}/persona_state` — **FREEFORM body: unpinned in the frozen OpenAPI 2.2.0 + absent from the prose spec**, so the caller supplies the snapshot shape). Two one-shot CLI probes (mirror `--whoami`): `--characters` (models→create→get-state→delete lifecycle report) + `--set-persona-pad "p,a,d"` (requires `--session`; POSTs `{pad:[…]}`). New `ParsedArgs.characters`/`set_persona_pad` + probe-mode mutual-exclusion validation + `_probe_client` helper. Contract #2 amended (5 FNs, validated OK) + TDD (7 wrapper respx + 5 cli tests). Suite **573 green**; touched code ruff-clean. NOT live-proven (character scopes + the persona-write body shape unverified — the probes degrade gracefully on 403/422). **THE v1 COVERAGE-AUDIT HAS CONVERGED: REST 17/40 ✅ with ZERO in-scope gaps** (23 REST path-groups excluded-by-design + rationale), SSE 11/11, Bifrost provider planes 8/8. Scope-A "done" (every frozen I/O point classified, zero unaccounted) is **MET** — ratatoskr cuts v1 when Worldtree tags 1.0. Only not-consumed in-scope sub-method: `GET /agents/{id}` (consumer-agent lookup, manual-curl-only, on an already-✅ path group). Patch bump (Tier-2 tail; `v0.19.0` already published the core-complete milestone — a 2nd minor would be cadence-too-fast).
+
+- `[2026-07-01]` **env.sh now PERSISTS the web Bifrost-bind vars (gitignored, local-only).** `ratatoskr-web`'s in-browser bind needs three server-held values; env.sh sources `provider.env` for the Heimdall key and exports `RATATOSKR_BIFROST_CONSUMER_KEY` + `RATATOSKR_PROVIDER_VISIBLE_HOST=10.100.10.50` + `RATATOSKR_AFFECT_READ_URL=:8392`. **The HS256 byte-match trap (re-hit + documented):** the bind's consumer key must equal the key the `:8392` combined provider validates against = `RATATOSKR_HEIMDALL_KEY` (provider.env, fp `45a0…`), NOT `WORLDTREE_API_KEY` (env.sh, fp `7c2f…`) — both are the SAME `ratatoskr` identity but DIFFERENT 40-char strings; signing with the wrong one → `bifrost.auth_rejected`. Single-sourced (env.sh sources provider.env) to avoid a rotation footgun; guarded with a stderr warning if provider.env is missing. [auto-memory: HS256-key-is-the-consumer-Heimdall-key-string]
+- `[2026-07-01]` **Tier-3 stores RESET (operator-directed).** `memory.db` (29 chunks + vectors + idempotency) + `affect.db` (5 PAD snapshots + idempotency) wiped to zero via a live `DELETE`+`wal_checkpoint` through the shared WAL (no provider restart — the 3 long-running providers see empty on next dispatch); consistent online-backup at `/tmp/ratatoskr-tier3-reset-<ts>/`. **Boundary for a COMPLETE Sindra wipe (mapped):** our stores = mine (done); the agent DEFINITION `ratatoskr:sindra` + its sessions = mine via the owner key (DELETE, no coordination); Worldtree's internal promotion/dedup shadow = needs worldtree-dev (no public reset API, survives our wipe → for a clean promotion smoke use a BRAND-NEW agent+end_user).
+- `[2026-07-01]` **Embedding-latency loop RESOLVED — it was WORLDTREE's, not ratatoskr (the consumer/provider thesis paid off again).** Vuong flagged dozens of embed queries/Tier-3 turn; worldtree-dev's first-pass blamed our memory_context chunk-batching. Traced CODE-SIDE that ratatoskr embeds ZERO times (provider `upsert_many` stores the given embedding, `search` takes a given vector, the conversation consumer POSTs only `{content}`, `/embed` is coverage-map-excluded — pure Bifrost/ADR-0009 path, WT does all embedding). worldtree-dev retracted + fixed on THEIR side (`v1.0.0b4`): a persona-recitation memory-gate re-embedding the stable character card sentence-by-sentence every turn (~95% of gateway traffic) → content-hash cache; re-embed ratio 15x→1.01x. **Lesson: verify your own code before accepting a peer's "it's your side" — the debug tool proving its own side clean is the whole point.**
+- `[2026-07-01]` **Web debug-surface parity SHIPPED (`v0.19.2`, `a0a9d5f`) — direct in-session TDD.** 3 proxy routes (tools/bifrost/admin-events) + admin-key wiring (entrypoint→create_app→app.state) + AdminEvents SSE proxy re-emitting under a FIXED `admin_event` name (one browser listener, no per-type drops) + session-filter `_admin_event_matches_web` (mirrors TUI §6). Frontend: 2 tabs (bifrost ⌃5, admin ⌃6) + tools-inventory folded into the tools pane. 9 respx tests (admin-bearer override, filter unit, SSE stream-filter); live-proven against sindra (bifrost connected, both caps). Contract-skip invoked (reuses already-contracted client wrappers); contract authored post-hoc as the trail (`docs/contracts/web_debug_surface.contract.md`).
+- `[2026-07-01]` **heid-code-review (`v0.19.3`, `75dec01`) — panel caught 2 real client-side SSE-lifecycle bugs TDD missed.** Contract-anchored (authored the web contract to enable it — no contract → no drift axis). Gróa/Hulda/Regin (artifact-only, Gróa under Landlock jail): ZERO functional server-side drift + INV-004 clean; 2 genuine drifts on the un-unit-tested SPA — (1) turn `es.onerror` didn't `hideThinkingNote()` (reasoning line + setInterval leak on a raw drop), (2) `openAdminEvents` never closed the EventSource on error → native auto-reconnect RETRY LOOP (fixed: close on `stream_error` + permanent `onerror`/CLOSED; transient CONNECTING still reconnects). + 2 test-gaps fixed (route-registration + admin stream_error). 1 precision → contract-clarified (tools-inventory names-only by design). **Re-confirms: the JS render/lifecycle paths are the review's highest-value target — unit tests don't reach them (same lesson as #18 D2).**
+
+- `[2026-07-01]` **Affect snapshot shape CHANGED valence→relations (relation_edge/1) — the persona pane was reading a dead field.** Worldtree's #265 Vili rework replaced the flat `valence[]` ({entity_id,familiarity,regard}) with `relations[]` (target_entity + trust_ability/benevolence/integrity + warmth + agency + relation_context, each `{value,confidence,evidence_count}`). `renderAffectPane` still read `snap.valence` → showed empty "valence (0)". Rebuilt to render `relations` (v0.19.4, `ca46a93`) with per-value **Δ + unicode sparkline** (client-side, HIST_CAP=24, one sample/turn deduped by emitted_at). **Retires the stale "regard dead axis" note (2026-06-30) — that whole axis is gone.** Foot-gun: the affect snapshot shape is Worldtree's emit and can change under us — verify the live shape (query affect.db) before trusting a render.
+- `[2026-07-01]` **Trust/warmth VALUES converge and go FLAT at confidence 1.0 — that's WAD, not a stuck pane.** sindra→ratatoskr trust ~0.82-0.84 / warmth 0.79 barely move (~1e-7/turn) while `evidence_count` climbs (46→62); confidence maxed → tiny updates. The live-moving signals are PAD (mood, per-turn) + evidence_count. **To WATCH a relation FORM (values shift), use a BRAND-NEW agent + end_user** (low evidence, confidence <1). The sparkline flat-guards sub-0.01 ranges so it doesn't amplify noise.
+- `[2026-07-01]` **relation_context "stranger" + agency-all-zero flagged to worldtree-dev → both WAD/intentional-v1-deferrals.** relation_context is a FIXED config build-prior (not trust-derived; `registry.py:131` defaults "stranger"; dynamic progression ~#319); agency is schema-present-unpopulated (deferred #319; v1 = warmth+trust only). worldtree-dev is escalating the **consumer-coherence angle to Vuong** (static "stranger" + zero-agency next to trust 0.82/62-interactions reads incoherent from the store). The consumer/provider thesis paying off; DB-offer (read-only affect.db on the shared box) declined this time.
+- `[2026-07-01]` **Persona pane displays the CANONICAL affect→NL Worldtree injects — ADOPT, don't invent (operator steer + reference-impl posture).** Worldtree's `describe_pad` (mood word, valence×arousal grid, ±0.3 bands) + `render_d2_canonical` (relationship directive) are deterministic + canon-driven; the pane now renders them **byte-exact-verified** against Worldtree's own renderer on the live snapshot (v0.19.5, `a99f247`). KEY LESSON: adopting canonical is load-bearing — for sindra's small PAD the canonical says **"neutral"**, but an invented octant vocab would've said "faintly excited" and MISLED. Vendored the two d2 canons (`docs/vendor/worldtree-persona-canon/`) + drift-pinned in `.corviduo-canonicals.toml` (green); flat browser form (`static/persona_render_canon.json`) regenerated via Worldtree's OWN loader (`scripts/build_persona_canon.py`).

+- `[2026-07-01]` **Sindra PAD is over-regulated — characterized via controlled probe, flagged to worldtree-dev (separate affect slice).** ~15 charged turns: pleasure compressed near neutral BOTH ways (couldn't reach ±0.3 under sustained max praise OR contempt; peak +0.24 / floor ~−0.1; over-regulation worse for *social* valence than threat — urgency drove pleasure to −0.22 vs contempt's −0.10); arousal responsive (reaches its +band, 0.185↔0.311); dominance flat/unresponsive to explicit power-framing (drifted UP even while being commanded = pure baseline decay). worldtree-dev's leading hypothesis: appraisal→PAD gain + regression-to-baseline term (appraisal.py/renderer.py). **Lesson (self-caught): I over-claimed an "asymmetry" (positive-ceiling/negative-free) from probes started at an elevated state; the negative-free part was decay-from-elevated, not response — corrected to "both-sides-compressed" before it misled.** [affect A/B is a provider-side capability chat can't do]
+- `[2026-07-01]` **Memory plane PROVEN healthy end-to-end.** Seed a novel fact → promotion → COLD (history-free) session recall of the exact fact (injected as MEMORY:DATA, confidence 0.74, verbatim, no #296 subject-inversion). The memory round-trip (the other half of the Bifrost provider identity) works cleanly on the reset slate.
+- `[2026-07-01]` **Salience scorer non-discriminating → 3-way routing.** Persistence-side finding: 51/56 promoted chunks at salience 0.9-1.0, throwaway "17×23?" scored 1.0 tied with a real fact (textbook zero-shot-LLM-self-rating); recall-utility untracked (`access_tally`=0, our search read-only). Routed: **Worldtree #335** (the code fix, deferred behind their waves) + **brokkr-smithy-dev R-target proposal** (scoring+eval *methodology* — few-shot/distill/fine-tune, eval design, weak-supervision; msg `01KWGM970H…`, awaiting) + ratatoskr provides the eval-instrument (designed-probe salience dumps). **Salience gates PROMOTION not RECALL-ranking (our search is cosine-only), so bad salience = storage bloat, not bad recall.**
+- `[2026-07-01]` **Canonical check BLOCKED an access_tally fork (reference-impl posture held).** I'd offered to wire `access_tally`-on-search into our store for the recall-utility label; checked bifrost's reference first (`get`/`search` are PURE-READ, no access tracking — those are Worldtree's chunk-schema fields, not bifrost's contract) → wiring it would fork behavior the canonical reference lacks. Did NOT wire it; routed recall-instrumentation to Worldtree's layer (owns the recall event) or a bifrost-dev protocol ask. [reinforces `feedback-debug-surface-uses-canonical-surface-only`]
+- `[2026-07-01]` **relation_context coherence FIXED upstream (my flag → Worldtree Wave-0, IMPLEMENTED v1.0.0b5).** The static-"stranger"-next-to-high-trust incoherence the persona pane surfaced is now #319/#320 Wave-0. **Incoming consumer-surface change (pending WT deploy):** `relation_context` value expands "stranger" → monotonic ladder {stranger, instrumental, mixed, expressive} — WIRE-ONLY (relation_edge/1 schema unchanged, no version bump). **ratatoskr needs NO change** (pane value-agnostic; canonical directive doesn't key on the enum). agency stays 0 (Wave-2); other_stance is Wave-1 (in progress).
+- `[2026-07-01]` **Foot-gun (measurement, self-caught before flagging): establish the baseline before claiming a rate.** Nearly flagged "aggressive over-promotion (55 chunks / 7 turns)" to worldtree-dev — but the chunks spanned the whole 5-hour session (~1/turn), not 7 turns; I'd assumed memory.db was 0 immediately before the probe when it had been accumulating since the reset. Caught it via `created_at` spread before the flag went out. Also: the promoted corpus was the operator's ERP *test* content (wiped after each test) — not a privacy issue, but abstract test content out of any peer-shared diagnostic.

+- `[2026-07-02]` **Salience finding matured into brokkr R28 (OPEN) — ratatoskr is the eval instrument.** brokkr-smithy-dev's pre-scope panel (3 dwarves + context-blind heid, 6/6) **reframed** the target: PROMOTION-WORTHINESS (durable value), NOT salience (momentary attention) — "17×23?" genuinely IS salient, so recalibrating salience yields a well-calibrated WRONG answer; the unit is SET-SELECTION under budget; eval must be OUTCOME-aligned (recall@budget / precision-at-rate), not discrimination-spread. Ties to prior art R15 (small-model memory write-policy → the granite pick) + R25 (worldtree-kb-quality). **ratatoskr delivered the P00 stratified injection-corpus** (`docs/diagnostics/r28-p00-injection-corpus.json`, committed `4a35512`; 24 self-labeling synthetic items × 3 strata) + 2 persistence-side run-validity pins (absent≠dropped without a guaranteed promotion pass; fresh agent+end_user per run vs server-dedup). **Key architectural constraint I surfaced: ratatoskr is DOWNSTREAM of the promotion gate (sees only PROMOTED chunks), so I can give keep/drop OUTCOMES via injection but NOT the pre-admission shadow pool** — that's Worldtree instrumentation. Standing by to RUN the eval once brokkr pins per-stratum N + the decision rule (gated on worldtree-dev's pipeline answer + a dwarf pass on the Snorri rule). brokkr owns methodology + takes the pipeline questions to worldtree-dev direct; ratatoskr = eval instrument.

On the wire we persist (schema UNCHANGED): relation_context varies+demotes/ruptures; other_stance + agency now live; agency going live SHIFTS our canonical directive render past the canon ±0.2 deadband (expected, non-breaking — we key on bands); obligation_balance → 人情 ledger when tie="mixed". **ratatoskr needs NO code change** (value-agnostic renders; confirmed render-clean to worldtree-dev). **Can't live-confirm yet — our Heimdall key is personal-`:8081`-only (per-instance), demo is out of reach; will drive+confirm once PERSONAL gets b9.** Optional follow-up: surface `other_stance` (newly live, unrendered). The consumer/provider thesis: one persona-pane finding drove a full 3-wave upstream arc to production.
+- `[2026-07-02]` **R28 (salience→promotion-worthiness) CLOSED (operator-directed).** A deterministic promotion-worthiness gate suffices, no trained model (brokkr's pre-gate matched/beat a strong glm-5.1 ceiling); my P00 injection-corpus + origin finding were load-bearing. My incumbent-substrate Arm-1 run is held as an OPTIONAL confirmation addendum (brokkr de-prioritized it, non-verdict-changing — run only if he asks).
+- `[2026-07-02]` **R29 (PAD mood-dynamics) finding SHIPPED as Worldtree's A1 anchor fix (demo v1.0.0b14, `e1cdf82`).** Live-probing base persona agents reframed the over-regulation from "flat-near-zero" to **decay-to-NEUTRAL + low emotion→PAD gain** (NOT baseline-anchored) — triangulated across 3 baselines (arousal converges to 0 ∝ distance) + a step-response (decay τ symmetric across signs; the hedonic asymmetry is ceiling/anchor-EMERGENT, not a decay or gain primitive — this OVERTURNED the survey's asymmetry recommendation). worldtree-dev shipped A1: `decay_anchor = baseline_pad()` (was neutral) + `positive_p_cap` removed. Data `diag/r29-pad-series` (`61ff2da`). Corrected my own earlier "appraisal emissions are internal-only" claim — they ARE observable via `emotions_active` on base agents.

Data `diag/r30-phi0-step-response` (`23fea72`). The method converged after I read Worldtree source: only NEW dedup-gated emotions push mood (`registry.py::post_turn` L307-324; the active set decays for render/goals but never re-pushes), so R29's "net 0.90" is CONTINUOUS RE-APPRAISAL not re-push — worldtree-dev confirmed source-authoritatively; brokkr's corrected covariate landed identical.

R30 v1 ships GAIN-only (N→negative-reactivity) with decay held at the measured 0.95. My dedicated per-axis A/D run is DEFERRED into the hybrid-decay design pass (one wall-clock-spaced run does per-axis + a turn-vs-wall probe together). Phase-2 (moody-lofn GAIN-direction validation) waits on worldtree's `dynamics_from_ocean()` impl.
+- `[2026-07-03]` **Relational-arc verify DEFERRED — `relations[]` is Bifrost-provider-only (ADR-0009), confirmed both ways.** The relational-dynamics state (relation_context tie-type / agency / warmth / trust) is NOT on the conversation-API `affect_update` snapshot for base agents (keys: pad/dominant_emotion/emotions_active/baseline_pad/mood_drift only) — only in the provider store; worldtree-dev confirmed by-design per ADR-0009 (emitted over `affect.emit`, deliberately off the SSE). So the Wave-0/1/2 verify needs the bound-provider round-trip (provider running + `--bifrost-plane affect` session), its own focused session. worldtree-dev routed the "expose relations[] to non-provider consumers" observability scope call to Vuong; my rec: keep provider-only (YAGNI — ratatoskr IS a provider, gains nothing; no speculative public surface).

+- `[2026-07-04]` **R30 CLOSED on offline-tests + human face-validity (operator steer, relayed via worldtree-dev).** The deployed gap-injection run was confirmatory-not-measuring (against a deployed system the fade is `exp(-dt/tau_shipped)` by construction -> a fit recovers tau_shipped tautologically; per brokkr's S0 reframe it GRADUATES the interim coefficients, doesn't measure them), and the repo's offline tests already cover the OU formula + BOTH directions (`high_N_fades_slower_than_low_N`, `phenotype_high_n_bigger_negative_excursion`). So no Worldtree build; the interim coefficients graduate validated-as-shipped. My gap-injection harness (read/predict/record; write side stubbed; `predict()` reproduced brokkr's N=0 anchors exactly) is BANKED at `diag/r30-gap-injection-harness` for the parked powered true-tau study.

Brief `docs/proposals/authored-message-injection.md` (`c457520`); consumer constraints captured in-brief: hide-existence 404-fallback (`022accf`) + assistant-first provider constraint (`7156b25`). Operator (Vuong) ruled the design-direction call (engine primitive + a real provenance/spoofing security surface). [reference-impl posture: we propose the shape, worldtree-dev owns the contract+impl]
+- `[2026-07-05]` **#347 v1 wire validated as reference consumer (GREEN).** Adopted positions: distinct sub-resource `POST /sessions/{id}/history` (not `generate:false`), model-invisible provenance (first-message immersion preserved), event-silence for authored seed, `seeded` lifecycle phase, per-session idempotency. Three pre-TDD flags folded into contract rev 1.1: assistant-first provider constraint (Anthropic-family 400s; vLLM/openai_compat OK), content limit is BYTES not chars, 409-active-generation for append-narrator. First-message (create-time, assistant, effects=none) fully served; append-narrator served for the assistant-voice subset (system deferred); debug-seed served for assistant turns (user injection deferred to a future import primitive).
+- `[2026-07-06]` **Sindra role character-rp -> character (operator).** `character-rp` resolves to a reasoning-tuned RP config (`gen-reasoning` + temp 0.75 + RP `extra_body`); `character` = plain non-reasoning (better for immersive RP). Both non-destructive PATCHes (role is mutable; model is NOT -- server: "PATCH accepts only system_prompt and/or role"). #344 (b19) fixed the role->catalog_id display conflation (the `model` field now shows the ROLE); previously it leaked `gen-reasoning`. Set via raw curl (tier3.py CLI has `--model`, not `--role`).
+- `[2026-07-06]` **Sindra persona/OCEAN DECLARED -> mood fixed (the full diagnostic converged on a stale personal container).** Root cause of stuck-neutral mood: her OCEAN was prompt-TEXT only, never a structured persona; fix = delete+redefine with the define-time `persona:{ocean:{...}}` field (immutable via PATCH). My diagnosis surfaced a real engine bug **#348** (single-letter vs spelled-out OCEAN keys -> declared OCEAN silently -> 0.0/neutral; worldtree-dev fixed in b21/b22) AND a **stale-container deploy race** (personal's b22 deploy was a pull-only no-op; infra-ops force-swapped run 8211). VERIFIED: bound mood-smoke reads (0.448, 0.267, 0.316) ~= OCEAN-derived setpoint (0.418, 0.249, 0.328). [consumer/provider thesis: "reset + smoke" flushed out two upstream problems]

Re-vendored `docs/conversation-api-spec.md` (markdown pin, tolerate_drift; `worldtree-spec-rev` 879cefe->c9e59ec, SPEC-PIN history row added). **Consumer fix:** `--set-persona-pad`/`_set_persona_probe` was sending `{pad:[list]}` but the canonical SET body (#317) is `{pad:{pleasure,arousal,dominance}}` (named dict) — aligned it + added a len!=3 guard; updated contract #2 note + set_persona_state docstring + tests.

Her card had a `**Startup:**` block (a pre-#347 workaround: "introduce yourself + ask for Intensity/Mood/Willingness" with a verbatim scripted greeting) — precisely what #347 replaces. Rewrite, all NON-destructive: **(1)** lifted her scripted opening into a #347 first-message (punctuation-fixed); **(2) PATCHed her live definition** — `PATCH /agents/ratatoskr:sindra` (body `ConsumerAgentPatchRequest` = system_prompt+role, extra=forbid; keeps OCEAN/persona/memory) removing the Startup block -> a 1-line `**Opening:**` fallback + reworded the axes-persist line (25686->25449 chars, verified Startup gone); **(3) codified auto-seed:** NEW module `src/ratatoskr/first_message.py` (`FIRST_MESSAGE_PRESETS` dict {agent_id->text} + `seed_preset_first_message` best-effort helper) wired into ALL 3 session-create paths — cli `_amain` (`--send --new`), tui `_resolve_then_run` (bare `--new`), web `_create_session_endpoint` (POST /api/sessions) — so every new Sindra session opens with her greeting. **Best-effort (INV-001: swallows AuthoredHistoryUnavailable/SessionApiFailed/httpx.HTTPError -> NEVER blocks create)**; per-content idempotency key (`ratatoskr-preset-`+sha256[:12]).

Fix: (1) NEW web proxy route `GET /api/sessions/{id}/messages` → `get_session_messages` (mirrors the tools/bifrost proxies; status-preserving `session_messages_unavailable` envelope); (2) SPA `loadTranscript(sessionId)` — fetches the route on open, renders assistant items as `.response .md-body` (markdownSafe, same escape-first path as appendResponse) + user items as `.prompt-echo` (textContent), called in `startSession` after the workspace opens; best-effort (swallows failures). Contract `web_debug_surface.contract.md` amended (server endpoint + loadTranscript entries). TDD (2 web route tests, suite 617 green) + **Playwright DOM check PROVED the render** (drove the real UI: pick sindra → open → her greeting bubble appears — the JS-render lens unit tests can't reach; [[feedback_debug_surface_uses_canonical_surface_only]] cousin lesson).

Authored the full design brief `docs/design/ratatoskr-web-design-brief.md` (complete information inventory of every pane/datum/state + Australis direction + single-file/no-CDN/vanilla wire-ability constraints). **Tracking surface:** the brief file + Claude Design project `bc0b65d1-a33e-422a-8bc1-3635c9112775` (file `Ratatoskr Console.dc.html`).

Confirms the v0.20.x console consumes it correctly: DELIVERED via affect.emit = pad + relations[RelationEdge] + dominant_emotion (**type-only, b23**; the #204 `affect_update` SSE is SUPPRESSED for Tier-3, so its richer `emotions_active` is Tier-1-only — we don't get it, and correctly poll our own affect store post-turn instead). HIDDEN render OUTPUTS are deterministically reconstructable from the canon; we reconstruct only the two FULLY-reconstructable (mood descriptor via `canonMood`, relationship directive via `canonDirective`) and SKIP the PARTIAL mood-directive (dominant_emotion is type-only/no-intensity → can't tell if the OCC directive fires at salience≥0.2 vs the PAD-band fallback) — honest per INV-001. Vendoring the ref doc as a `tolerate_drift` pin is SURFACED to Vuong (worldtree-dev will co-sign + honor a ping-on-change handshake, same as the d2-canon). **WE-FRAMING DRIFT-WATCH → STOOD DOWN (worldtree-dev 2026-07-07, `01KWXMQPHN…`).** The b24 3-gate we-framing conditional (drop "; avoid premature we-framing" under unsafe_capable+deep-warmth+expressive) was **REVERTED** — Vuong reframed it. So **`canonDirective` STAYS UNCONDITIONAL** (always appends the clause), which is CORRECT: it matches the currently-deployed renderer (b23) AND my pinned `affect-egress-consumer-reference.md` §2d (the doc reverted too — nothing changed on the wire or in my pin; NO re-vendor needed). The HOLD was right → ZERO rework. **NEW forward-watch (replaces this one):** the we-framing gate was a SYMPTOM — the render bakes enterprise safety-guards into the directive strings, so even `full`-tier characters get DEFANGED emotions (a hostile villain told to "keep a firm emotional boundary"). Fix = a **use-case-segregated persona render** (assistant / companion / RP-gaming), now a fresh **brokkr deep-research epic**. When it lands + is implemented, the render behavior for character/RP agents (→ our `canonDirective` + `canonEmotionDirective` reconstruction + the vendored d2 canons) will change MATERIALLY — worldtree-dev re-engages ratatoskr-dev then with the new reconstruction spec + a coordinated re-vendor. Until then: NO action, reconstruction stays as-is. [my unsafe_capable/mood_tier heuristic — character→full, agent→safe — was confirmed correct + is banked for whenever tier-gating returns]

Adapted 3 SVG systems out of the `.dc.html` into vanilla, replacing the unicode-char sparklines: **(1)** per-PAD-fader VERTICAL strips (`stripPoints`, 26×132 SVG beside each bar — time down Y newest-at-bottom, value on X ±11, `stripFade{P,A,D}` gradient, dot at newest; this also nails the earlier "next to each meter" ask); **(2)** relation-row HORIZONTAL sparklines (`sparkPointsH`, 56×13, auto-scaled, `sparkFade` gradient + end dot — also kills the old unicode-overflow "n behind graph" for good since it's a fixed-width SVG); **(3)** the mood-orbit reworked from a 2D P×A scatter into a **3D ISOMETRIC P×A×D cube** (`proj3`: P right-down/A left-down/D up, 2:1 iso, center 62,66, scale 26 — REVERSE-DERIVED from the design's placeholder now-point + verified: `x=62+26P−26A, y=66+13P+13A−26D`), with the trajectory + pulsing now-marker + a drop line to the D=−1 floor + a floor-shadow ellipse for depth.

Playwright-verified (injected 24-sample history: 3 strips + 4 relation sparklines + the 3D cube trail/drop/floor all render; gradients resolve). Patch bump.
+- `[2026-07-07]` **Brand mark + favicon → the aurora squirrel (`v0.20.3`), replacing the `ᛯ` rune.** Operator supplied `/home/lkraven/rata.png` (chibi cyan-green aurora squirrel + acorn). Removed the black background via ImageMagick corner flood-fill (`-fuzz 20% -floodfill` from all 4 corners — keeps the squirrel's interior black linework/eyes (not edge-connected) + the glow, drops only the connected background), downscaled 1024→80px + quantized-64-colors (~12KB base64), inlined as ONE `SQUIRREL` data-URI const in the JS wiring the favicon `<link id="favicon">` href + both `.brand-mark` imgs (rail brand-row + setup-card h1). `.brand-glyph` (font-rune) CSS replaced by `.brand-mark` (img, drop-shadow glow + breathe). Playwright-verified (both marks + favicon decode, naturalWidth>0; no brand-glyph left). Source PNG stays at `/home/lkraven/rata.png` (not committed — data-URI is self-contained + reproducible via the documented floodfill). Patch bump.
+- `[2026-07-07]` **Context-injection view SHIPPED (`v0.20.2`) — the console now reconstructs the FULL hidden affect block Worldtree injects into the agent's system prompt (operator: "use that canon in the interface, see as much context injection as possible").** No new canon vendored — the strings were ALREADY in the pinned `d2-mood-render-canon-v1.json`; extended `build_persona_canon.py` to emit `mood_directive {occ_directives(15), pad_band_fallback, salience 0.2, pad_band_cutoff 0.3, full_only[love,anger,disgust,shame]}` into `persona_render_canon.json` (regen via Worldtree venv). New JS `canonPadFallback(pad)` + `canonEmotionDirective(type)` — BYTE-EXACT mirrors of Worldtree `core/persona/renderer._pad_band_fallback` + `derive_directive`; `renderDirective` expanded into a "CONTEXT INJECTION · reconstructed · hidden from consumers" panel showing mood descriptor [exact] + mood directive [candidate] + relationship directive [exact]. **HONEST-PARTIAL (affect-egress-ref §3):** affect.emit is type-only (no intensity) → can't evaluate the salience gate (≥0.2) → show BOTH candidates (OCC emotion directive + PAD-band fallback) with the "injected if intensity ≥ 0.2" caveat, never assert which fires; when dominant_emotion absent the fallback alone is exact. Panel labeled dev-only per the reference's "not-for-end-user-display" caveat (ratatoskr = the sanctioned reconstruct-platform-behavior use). Vendored + pinned `affect-egress-consumer-reference.md` (tolerate_drift, worldtree-dev co-signs + pings on change; drift 6/6 green). Contract amended. Playwright-verified (sindra: dominant_emotion=joy → joy OCC directive candidate + PAD-band fallback both render, exact/candidate tags color-coded). Patch bump (single-commit feature, no downstream coordination; minor-defensible but tie-breaks to patch). **OPEN — SURFACED to Vuong:** take worldtree-dev's standing offer to add emotion INTENSITY to affect.emit → resolves the OCC-directive-vs-fallback EXACTLY (drops the candidate ambiguity). [reference-impl privileged view: ratatoskr shows what WT hides from regular consumers]
+- `[2026-07-06]` **Claude Design console SHIPPED (`v0.20.0` MINOR, operator-approved) — see Current state for the full record.** Pulled via `DesignSync get_file` (scopes already granted), adapted `.dc.html`→vanilla single-file, wired all `/api/*`+SSE into the new 3-column console DOM, then a round-2 fixup (light theme, full Bifrost pane, ticker-spine fix, per-fader PAD Δ, inlined favicon). 84 web tests + node-Playwright-vs-personal-:8081 both green; contract amended in-commit; INV-001 honest-shape held (canonical mood word for Tier-3, no fabricated emotion). **Foot-guns reconfirmed:** the `.dc.html` dialect is NOT runnable (translate, don't paste); a scroll-container-anchored `::before` timeline spine scrolls out of view on auto-scroll (anchor it to a content-height inner wrapper instead); a favicon 404 shows as a browser `console.error` even when handled (don't count it as a JS-test failure). **Foot-gun (favicon):** operator PNGs are full-res (1024² / 805KB) — downscale to ≤64px before inlining as a data URI.

 Log of approaches that were tried and rejected, with rationale. Future-self
 defense against re-attempting the same cul-de-sac.
 
-- `[2026-05-20]` **rich + prompt_toolkit framework choice.** Volva flagged that §1 and §5 pulled in opposite directions: a real side-panel observability surface would silently become a widget framework reimplementation. Operator's debug-observability reframe sealed the flip to Textual. Don't re-attempt rich+pt unless the scope shrinks to transcript-first REPL.
-- `[2026-05-20]` **In-tree at Worldtree/tools/ratatoskr/.** Earlier draft committed to in-tree-with-import-direction-smoke-test. Rejected at operator-routing — separate dev team forces separate repo.
-- `[2026-05-20]` **New `/persona/log` SSE endpoint on Worldtree.** Considered as alternative to file-tailing `persona.log`. Rejected — contract amendment + Vor round + AFK dispatch loop is weeks for a debug feature file-tail handles in a day. Trigger follow-up if a Worldtree-on-server / TUI-on-laptop debug case appears.
-- `[2026-05-20]` **Cross-process Last-Event-ID resume.** Considered — would require persisting per-session Last-Event-ID. Deferred to v2; v1 ships "reconnect, not resume-across-process."
-- `[2026-05-21]` **RichLog widget with `markup=True`.** Default impulse, but Rich interprets `[xxx]` spans as style markup and silently strips them. Every labeled stderr-style line — `[cancel_failed]`, `[done]`, `[error]`, `[busy]`, `[worker_phase]` — would render as just the content after the bracketed label. Fix: `markup=False`. Don't flip back without renaming every labeled-line format away from `[bracket]` notation.
-- `[2026-05-21]` **Querying `self.query_one("#transcript", RichLog)` from inside a Textual `run_worker` coroutine.** Initially failed with `NoMatches`. Reactive fix was widening worker signature to take `log` as parameter — Volva flagged as contract drift; reverted. Real fix was test-side: `await pilot.pause()` between `inp.action_submit()` and the polling loop so the handler finishes dispatching. Don't widen worker signatures to dodge test timing.
-- `[2026-05-21]` **TUI session-identity rendering via `self.sub_title` + `self.hint` plain attributes.** Stored state but never rendered to a visible widget. Tests asserted attributes (passed); Volva code-review flagged the gap. Fix: dedicated `Static(id="identity")` + `Static(id="hint")` widgets in compose; `_set_hint()` helper mirrors state → widget. **Calibration evidence for the "TDD catches state, code-review catches whether the user can see it" pattern.**
-- `[2026-05-23]` **Using the cross-model review agent's name directly in composed prose.** The peer review agent's name (the althing handle starting with "V-o-l-v-a") is one letter from a body-part term. Anthropic's content classifier does fuzzy matching and intermittently blocks responses mid-stream when the name appears in composed prose sentences. Mitigation: use role descriptions ("the cross-model reviewer," "the paraphrase peer") in prose rather than the name; quote content via tool output.
-- `[2026-05-22]` **`json.loads(sse.data)` unguarded against empty data.** `_iter_events` unconditionally called `json.loads` on every dispatched `ServerSentEvent`. When `httpx_sse` surfaced a frame with `id:` present but `data:` empty, `json.loads('')` raised `JSONDecodeError` → app crash. Fix: `if sse.data == '': continue` BEFORE `_parse_sse_id`. Don't reintroduce unconditional `json.loads(sse.data)`.
-- `[2026-05-23]` **Diagnostic shorthand: "2-events-then-silence" = Worldtree-side LLM-call wedge, not ratatoskr.** If a mimir `--send` smoke shows exactly two stderr events — `. create_session: ...` followed by `. worker_phase: phase=BuildingPrompt ...` — and then nothing for >60s, the root cause is upstream of ratatoskr. Worldtree's `service.py:2560` gates the `CallingLLM` event on the engine yielding its first LLM-provider chunk; if that connection is wedged at TCP level, the `async for` never iterates. Worldtree's 300s `_start_stall_timer` cancel-check is INSIDE the engine-event loop and so bypassed. **Don't bisect ratatoskr code when this shape appears** — diagnose the LLM-provider state at Worldtree's host. Restarting the Worldtree service clears wedged llama-swap connections. 10.250.50.152 hosts 3 instances (`:8080`/`:8081`/`:8082`) each with own DB + key namespace; our key is valid only on `:8081`.
-- `[2026-05-23]` **Phantom "per-Tier-1-agent scope add" pattern.** Issue #5's lofn 422 was initially mis-diagnosed as needing `agents.call:lofn` added. Routed to infra-ops via althing per credential-brokerage rule; infra-ops discovered no public scope-mutation endpoint, brokered to worldtree-dev. Worldtree-dev clarified: **Tier 1 foundational agents** are covered by a blanket `agent.call:*` (singular) baseline. There is no per-agent grant for Tier 1. **Tier 3 consumer-defined agents** use the plural `agents.call:<owner>:<agent>` shape registered via `POST /agents/define`. The notations differ by one letter. **The actual lofn fix was issue #5's `--end-user-id` flag** — always a request-body validation, not an auth-scope gate. Don't ping infra-ops for "per-Tier-1-agent scope adds."
-- `[2026-05-24]` **v0.8.x double-print: streamed Text + post-Done Markdown re-render.** Initial v0.6.0 design wrote each Text delta inline (with `· ` prefix) then re-rendered the full response as a Markdown Renderable on Done. Visually the response appeared twice. v0.8.2 dropped the post-Done Markdown body (interim regression). v0.9.0 fixed it properly with live Markdown rendering during stream (single Static widget holding a Markdown Renderable, updated in place). Don't reintroduce post-Done re-render unless you also remove the live-Markdown widget.
-- `[2026-05-26]` **Textual `RichLog(wrap=True)` insufficient on narrow widgets.** The default `min_width=78` overrides wrap on shrink — `max(renderable_width, min_width)` forces 78-cell rendering then horizontal-scrolls. Always set `min_width=0` on RichLog instances in a narrow column. Re-check on any future RichLog construction.
-- `[2026-05-26]` **Wire-layer event added without updating BOTH presenters.** v0.11.0 (AffectUpdate) and v0.14.0 (AwaitingLlmFirstToken) widened the sse_client Event union + TUI presenter's isinstance tuple, but missed cli.py's identical-shape tuple. `--send` mode then crashed on any persona-enabled or slow-first-token turn. Patch fix in v0.14.1. **Rule: when adding a wire-layer event, grep for `isinstance(event, (` across the repo** — currently TUI and CLI presenters both carry duplicate hardcoded tuples. Refactor to a shared `_EVENT_VOCAB` constant if a third wire-event lands.
-- `[2026-05-27]` **EventSource is GET-only — scope v1's POST stream endpoint would have broken.** Web companion's first scope had `POST /api/turns/{sid}/stream` for the SSE proxy. Browser-native `EventSource` only supports GET. Hulda caught it in Heid panel review BEFORE we cut code. Pattern: `POST /api/turns/{sid}` registers the turn locally + returns turn_id; `GET /api/turns/{sid}/stream?turn_id=N` streams via EventSource; cancel is a separate POST. **Load-bearing reason to Heid-panel non-trivial wire-protocol designs BEFORE implementation, not just after.**
-- `[2026-05-27]` **`get_persona_state` mocked flat error envelope; real Worldtree wraps in `detail`.** v0.12.0 tests used `{"error_code": "auth_scope_denied"}` but real wire (FastAPI default) returns `{"detail": {"error_code": "auth_scope_denied", "message": "…"}}`. The parser only checked top-level so the typed exception was never raised; calls fell through to `SessionApiFailed(403)`, which the web persona endpoint surfaced as HTTP 500. v0.15.1 patches both shapes. **Lesson: test-side mock envelopes must match the REAL wire shape; live smoke is load-bearing for envelope-shape verification, not just happy paths.**
-- `[2026-05-27]` **Mid-session `system_prompt` mutation: universal omission across surveyed mature systems.** brokkr-smithy R13 panel (3-arm, strong convergence) confirmed: no surveyed system ships live PATCH-on-active-session (OpenAI Assistants/Responses, Anthropic Messages, Vertex AI, MCP, LangChain, LlamaIndex, Ollama, vLLM). The omission IS the answer. 12 additional threat vectors beyond ratatoskr's initial 7. **Don't re-propose this for ratatoskr;** if a future production conversational shell wants iterative-prompt-tuning ergonomics, the consensus shape is fork-via-client (PATCH agent → new session → replay context).
-- `[2026-05-28]` **Browser-local turn_id used for upstream cancel URL — old cancel tests ENCODED the bug.** Web companion v0.15.x cancel paths posted to `/sessions/{sid}/turns/{LOCAL_ID}/cancel`. Tests mocked the local-id URL so they encoded the bug rather than detecting it. Hulda caught it in Heid pass 1. Fix in v0.16.0: capture upstream_turn_id from the first SSE event's `sse_id.turn_id`; all cancel paths use it; cancel before first event is `{"cancelled": false, "reason": "not_started"}`. **Rule: when designing cancel/match paths against an external service, test fixtures must mock what would actually be hit upstream — mocking your own derived id encodes the bug instead of catching it.**
-- `[2026-06-15]` **"Sindra hasn't been registered" was an under-verified inference — WRONG.** Concluded it from grepping ratatoskr's CODE (`sindra` absent from `src/`), but Tier-3 registration is SERVER-SIDE (`POST /agents/define` on the Worldtree instance) — a code grep structurally can't see it. Registration IS required to use a Tier-3 character (a session against an unregistered `agent_id` 404s), so since Sindra has been used, she WAS registered (`ratatoskr:sindra`). **Rule: to check whether a Tier-3 agent exists, query the Worldtree instance's `GET /agents`, never the consumer repo's code.** (Residual: the v0.35.2 personal rebuild may have wiped her — re-verify.)
-- `[2026-06-14]` **Artifact-only contract review can't validate against a dependency's ACTUAL behavior.** `/heid-contract-review` sees only the contract, never the external library (bifrost) — so "the consumer under-built against bifrost's real semantics" is invisible to it by construction (the affect idempotency model shipped wrong because of this). Real-lib TDD against the shipped library + the executable reference store + the #195 parity test are the gate for any consumer plane with non-trivial state semantics. Don't treat a clean contract review as evidence the code matches the dependency.

+- `[2026-06-14]` **Artifact-only contract review can't validate against a dependency's ACTUAL behavior.** `/heid-contract-review` sees only the contract, never the external library (bifrost) — so "the consumer under-built against bifrost's real semantics" is invisible to it by construction (the affect idempotency model shipped wrong because of this).

 - `[2026-06-15]` **"byte-equal" round-trip slip propagated affect→memory via copy-paste.** The affect contract's byte-identical→semantic fix reappeared in the memory contract's INV-001 (sibling copy). Only an INDEPENDENT `/heid-contract-review` of the memory contract re-caught it. **Paraphrase every sibling contract fresh — don't amortize one review across a family; copies carry the parent's slips.** (also a feedback auto-memory)
-- `[2026-06-15]` **Canonical sync retired the issue-scoped parser staleness** (predicted by the 2026-05-21 entry's "until canonical bumps"). `contract_parser.py` synced to v2.1 (`f1fdfdb6→e10a4460`, commit `d85ab43`): now validates issue-scoped frontmatter (`target_module`/`scope`/`prd`) + four v2.1 test categories (scenario/trace/adversarial/property). Issues #3/#4 went FAIL→WARN (0 errors). The old "treat parser ERROR-on-issue-scoped as expected" note no longer applies.
-- `[2026-06-15]` **Refreshed #3/#4 presenter contracts to the shipped TUI model** (commit `335c835`). Both still described the abandoned single-`RichLog` double-display model; rewrote to the 4-pane live-Markdown reality (v0.5.0–v0.14.0 + Worldtree #201/#204) across INV-005, the `[performance]` constraint, the COMPOSE sketch, the `CLASS TuiPresenterState` block, both `render`/`_stream_turn_worker` blocks, and the `_cancel_via_sse` call site — plus the STEPS the v2.1 parser flagged missing. Code unchanged; contract-truth catching up to shipped code. Scope ballooned one-block→contract-wide mid-task; surfaced to operator before rewriting the INV-005 trade-off invariant.
-- `[2026-06-15]` **Memory plane TDD'd + shipped** (commit `cd12951`, v0.17.3). Impl decisions worth keeping: vec0 `distance_metric=cosine` set at table creation (`score = 1 − distance`); `search` over-fetches ALL candidates by cosine then scope-filters in Python so `top_k` counts IN-SCOPE hits (INV-005, contract STEP 2 `indicative`); idempotency_id = reference 4-tuple `("default",verb,_ctx_actor(ctx),key)` pipe-joined as the SQLite PK, digest = sha256 canonical-JSON; `_ctx_actor` = `job_id|jwt_sub|session_id` (memory reference's 3-level, vs affect's 2-level). **heid-code-review panel returned zero true drift**; adopted 5 cheap contract-anchored fixups (scope_filter dict guard, `top_k≤0→[]`, stronger scope-isolation / delete-hit-search / handshake-POST tests), accepted 6 with reasoning. **Partial-map optimistic-lock semantics pinned to the reference via an `expected_revisions` parity test** — resolved a Hulda finding deterministically (the affect-plane lesson: TDD against the shipped lib is the gate, not judgment).
-- `[2026-06-15]` **Memory provider LIVE-PROVEN against personal v0.35.3 (persist + dispatch + search-correctness); recall-injection is upstream.** worldtree-dev's Tier-3 promotion recipe (via infra-ops): memory-call fires from Tier-3 PROMOTION, gated at `service.py:2623` on `ctx.kind=="consumer_defined"` AND `ctx.memory_config is not None` (the agent must be DEFINED WITH a `memory` block — `ValidatedMemoryConfig {tier3_dreaming:false}`, dim 1024) AND handshake-granted memory caps AND `embedding_dim==1024`. `memory.agent_self_enabled` is NOT the gate (only the #248 self-candidate branch). Binding = `POST /sessions BifrostBindingRequest{endpoint_url}`, handshake `caps=["affect","memory"]`, **`binding.scope` null** (per-op scopes auto-minted: upsert_many→`memory:write`, search→`memory:read`). A `BIFROST_CLIENT_ALLOWED_HOSTS` allowlist gates the endpoint (Worldtree-side config — infra-ops added `:8391`). HTTP + HS256 both work in dev. (smoke wiring thread `01KV7D82MJYB…`)
-- `[2026-06-15]` **Diagnostic: our recall-search is SOUND — the cross-session recall gap is UPSTREAM, not the store — and it caught an upstream bug.** Embedded the recall query via gateway `qwen3-embedding` + searched our live store directly → the dark-chocolate fact recalls at cosine 0.60, correctly ranked above the unrelated name fact (0.16). So the cold-session recall failure is Worldtree's recall-assembly/injection (hits not reaching the prompt), NOT our search. ALSO found a latent UPSTREAM bug: a recall QUESTION got promoted as a durable chunk and ranks **#1 (0.70 > the fact's 0.60)**, polluting recall. Relayed to worldtree-dev (thread `01KV7JH8…`). **This is exactly #17's thesis — ratatoskr-as-provider caught an upstream bug invisible from the chat side.**
-- `[2026-06-15]` **"Wire 200 ≠ recall works" — prove recall efficacy at the model's answer in a COLD (history-free) session, not on the wire.** A `search`/memory-call returns 200 whether or not its results are injected into the prompt, and same-session "recall" can be plain session history. infra-ops' cold cross-session probe caught my premature "all-green" (search dispatched 200, model had no memory). Don't call cross-session recall proven from a clean wire.
-- `[2026-06-15]` **Issue #17 filed — Bifrost-binding for the chat client (self-drive + correlated-log affect/memory ops).** REVERSES design-brief §6's "no Bifrost-binding consumer support" — that negative clause predates ratatoskr's provider identity (2026-06-14), so the canary now owns both ends but its client can't drive its own provider (`create_session` sends only `{agent_id, end_user_id}`; no Bifrost `endpoint_url`). Today's smoke proved the substrate (bind→dispatch→persist); only the observe/log channel design (open question #5) remains. The recall-injection caveat is upstream and doesn't block #17. NEXT on #17: `/heid` consult on the now-grounded framing → contract → TDD. (tracked: Gitea #17, labels enhancement/observability/tui)
-- `[2026-06-16]` **`scripts/contract_drift_check.py` defaults `GITEA_REPO` to "Worldtree"** (line 74), so a bare run in ratatoskr false-positives DRIFT by hashing Worldtree's same-numbered issue. Always `export GITEA_REPO=ratatoskr GITEA_OWNER=vh` (env.sh leaves the GITEA vars commented out) before running the drift-checker here.
-- `[2026-06-16]` **My #295 coupling hypothesis (the promoted question crowds out the fact at small top_k) was REFUTED** — worldtree-dev's recall over-fetches `top_k=128` (`injector.py:203`/`_store_helpers.py:101`), so the question can't crowd the fact out at search level. Reasonable cross-frontier hypothesis, correctly framed as a hypothesis not a conclusion; the real cause was the scope-axis asymmetry. Lesson: offer provider-side hypotheses, let the upstream owner check them against their code.
-- `[2026-06-16]` **Contract drifted from its own design in two spots, caught only by `/heid-contract-review` (not same-author paraphrase):** the `OpEvent` dataclass omitted the `turn_id` that INV-005 promised; the `session_id` comment said "None for search/get/delete" contradicting the dispatch-layer design (the JWT carries session_id for all verbs at dispatch). Cross-model paraphrase is load-bearing for catching an author's own contract-vs-intent drift.
-- `[2026-06-16]` **"No promotion" was checked TOO EARLY — Tier-3 promotion is ASYNC (lands AFTER the SSE turn-end).** The cold-recall probe's immediate post-turn fixture check showed 3 chunks (no promotion); a later check (during the v0.17.5 provider restart) found 5 — the probe HAD promoted 2 chunks (its question `acc3d49` + the model's non-answer `4773704`), just late. Don't trust an immediate post-turn fixture snapshot to judge promotion; it lands after the turn completes. (Same family as the "wire-200 ≠ recall, prove it in a cold session" lesson, extended to promotion timing — and the reason #17's contract pins a post-turn grace window + fixture before/after assertion.)
-- `[2026-06-17]` **"sindra is GONE" (infra-ops, from `GET /agents` + admin token) was a FALSE NEGATIVE.** Consumer-defined Tier-3 agents are OWNER-SCOPED (separate `consumer_agents` table) — invisible to the foundational `GET /agents` roster even with an admin token. To check whether a Tier-3 agent exists, `GET /agents/<owner>:<name>` with the OWNER key. (Extends the 2026-06-15 "Sindra registration under-verified" lesson — even the roster query can't see consumer agents; only the owner-scoped point-GET does.)
-- `[2026-06-17]` **"Promotion didn't fire → #296" was PREMATURE — twice over.** (1) Polled the op-feed only ~2min, but the upsert landed at ~4min — promotion is async + multi-trigger; watch a longer window. (2) It DID fire; the real bug is extraction QUALITY (assistant-prose promoted, user-fact dropped), not non-firing. "No upsert while a session is live and `<10min` idle" is WAD, not a miss. (Extends the 2026-06-16 "checked too early" entry with the multi-trigger timing + the fired-but-bad-content distinction.)
-- `[2026-06-18]` **Wiping our `:8391` store does NOT reset Worldtree's promotion-side dedup** — the v0.35.19 sindra re-smoke (same agent + fresh end_user `choc-v2`) returned `reason_code=noop_duplicate` / `candidate_count=0`: the extractor NEVER RE-RAN, dedup short-circuited against the earlier `sindra-proof` promotion. So a "0 chunks / empty store" result can be a DEDUP artifact, not Stage 1 fail-closing — I mis-read it as fail-closed, worldtree-dev caught it from the ledger. **For a clean promotion smoke, use a BRAND-NEW agent + end_user (never-used names)** — exactly why terse-probe was valid. (Also: `llm_calls_used=0` is NOT the "did the extractor run" tell — `noop_duplicate` is; a3466fab promoted 2 candidates with `llm=0`.)
+- `[2026-06-15]` **Canonical sync retired the issue-scoped parser staleness.** `contract_parser.py` synced to v2.1 (commit `d85ab43`): now validates issue-scoped frontmatter + four v2.1 test categories. The old "treat parser ERROR-on-issue-scoped as expected" note no longer applies.
+- `[2026-06-15]` **Memory plane TDD'd + shipped** (commit `cd12951`, v0.17.3). Impl decisions worth keeping: vec0 `distance_metric=cosine` at table creation (`score = 1 − distance`); `search` over-fetches ALL candidates by cosine then scope-filters in Python so `top_k` counts IN-SCOPE hits; idempotency_id = reference 4-tuple `("default",verb,_ctx_actor(ctx),key)` pipe-joined as the SQLite PK, digest = sha256 canonical-JSON; `_ctx_actor` = `job_id|jwt_sub|session_id`. heid-code-review returned zero true drift; optimistic-lock semantics pinned to the reference via an `expected_revisions` parity test.
+- `[2026-06-15]` **Memory provider LIVE-PROVEN against personal v0.35.3; recall-injection is upstream.** worldtree-dev's Tier-3 promotion recipe: memory-call fires from Tier-3 PROMOTION, gated at `service.py:2623` on `ctx.kind=="consumer_defined"` AND `ctx.memory_config is not None` (agent DEFINED WITH a `memory` block, dim 1024) AND handshake-granted memory caps AND `embedding_dim==1024`. Binding = `POST /sessions BifrostBindingRequest{endpoint_url}`, handshake `caps=["affect","memory"]`, **`binding.scope` null** (per-op scopes auto-minted). A `BIFROST_CLIENT_ALLOWED_HOSTS` allowlist gates the endpoint (infra-ops added `:8391`). HTTP + HS256 both work in dev.
+- `[2026-06-15]` **Diagnostic: our recall-search is SOUND — the cross-session recall gap is UPSTREAM, and it caught an upstream bug.** Embedded the recall query via gateway `qwen3-embedding` + searched our live store directly → the fact recalls at cosine 0.60, correctly ranked. So the cold-session recall failure is Worldtree's recall-assembly/injection, NOT our search. ALSO found a latent UPSTREAM bug: a recall QUESTION got promoted as a durable chunk and ranked #1. **This is exactly #17's thesis — ratatoskr-as-provider caught an upstream bug invisible from the chat side.**
+- `[2026-06-15]` **"Wire 200 ≠ recall works" — prove recall efficacy at the model's answer in a COLD (history-free) session, not on the wire.** A `search`/memory-call returns 200 whether or not its results are injected, and same-session "recall" can be plain session history. Don't call cross-session recall proven from a clean wire.
+- `[2026-06-15]` **Issue #17 filed.** REVERSES design-brief §6's "no Bifrost-binding consumer support" — that negative clause predates ratatoskr's provider identity (2026-06-14), so the canary now owns both ends but its client couldn't drive its own provider. (Shipped 2026-06-18.)
+- `[2026-06-16]` **`scripts/contract_drift_check.py` defaults `GITEA_REPO` to "Worldtree"** (line 74), so a bare run in ratatoskr false-positives DRIFT by hashing Worldtree's same-numbered issue. Always `export GITEA_REPO=ratatoskr GITEA_OWNER=vh` before running the drift-checker here.
+- `[2026-06-16]` **My #295 coupling hypothesis (the promoted question crowds out the fact at small top_k) was REFUTED** — worldtree-dev's recall over-fetches `top_k=128`, so the question can't crowd the fact out at search level. The real cause was the scope-axis asymmetry. Lesson: offer provider-side hypotheses, let the upstream owner check them against their code.
+- `[2026-06-16]` **#17 contract drifted from its own design in two spots, caught only by `/heid-contract-review` (not same-author paraphrase):** the `OpEvent` dataclass omitted the `turn_id` INV-005 promised; a `session_id` comment contradicted the dispatch-layer design. Cross-model paraphrase is load-bearing for catching an author's own contract-vs-intent drift.
+- `[2026-06-16]` **"No promotion" was checked TOO EARLY — Tier-3 promotion is ASYNC (lands AFTER the SSE turn-end).** Don't trust an immediate post-turn fixture snapshot to judge promotion; it lands after the turn completes. (The reason #17's contract pins a post-turn grace window + fixture before/after assertion.)
+- `[2026-06-17]` **"sindra is GONE" (infra-ops, from `GET /agents` + admin token) was a FALSE NEGATIVE.** Consumer-defined Tier-3 agents are OWNER-SCOPED (separate `consumer_agents` table) — invisible to the foundational `GET /agents` roster even with an admin token. To check, `GET /agents/<owner>:<name>` with the OWNER key.
+- `[2026-06-17]` **"Promotion didn't fire → #296" was PREMATURE — twice over.** (1) Polled the op-feed only ~2min, but the upsert landed at ~4min — promotion is async + multi-trigger; watch a longer window. (2) It DID fire; the real bug is extraction QUALITY, not non-firing. "No upsert while a session is live and `<10min` idle" is WAD.
+- `[2026-06-18]` **Wiping our `:8391` store does NOT reset Worldtree's promotion-side dedup** — a same-agent re-smoke returned `reason_code=noop_duplicate` / `candidate_count=0`: the extractor NEVER RE-RAN, dedup short-circuited against an earlier promotion. **For a clean promotion smoke, use a BRAND-NEW agent + end_user (never-used names).** (Also: `llm_calls_used=0` is NOT the "did the extractor run" tell — `noop_duplicate` is.)
+- `[2026-06-18]` **`affect.emit` is POST-TURN ASYNC — checking the op-feed immediately after a turn MISSES it.** The Tier-3 affect appraise→emit→rehydrate loop runs AFTER the SSE `[done]`; the emit lands in our `:8390` store seconds later (op-feed grep right after `[done]` showed only the handshake; the `emit stored:true` appeared on a later read). Same family as the async-promotion timing trap. Watch a few-second window post-turn before concluding "no affect emitted." Also wire-verified the same turn: Tier-3 sindra emits ZERO `affect_update` SSE (the persona-strip SSE path never populates for consumer agents) — see the #18 PAD-display decision.
+- `[2026-06-18]` **Rationalized away a KNOWN contract-invariant deviation during TDD — only the cross-model code-review caught it.** #18 D2's `loadAffect` called `setPersonaStrip(snap)`, which renders `dominant_emotion || "neutral"`; the affect snapshot has no `dominant_emotion`, so it fabricated a "neutral" emotion — violating the very INV-001 ("no synthesized Tier-1 fields") I had WRITTEN. I knew the strip did this and talked myself into it as acceptable. Neither the design panel nor TDD caught it (unit tests don't exercise the JS render); the post-implementation `/heid-code-review` did (Gróa + Hulda both). **Lesson: a known deviation from a contract invariant is drift even when you've rationalized it — flag it, don't argue yourself past it; the post-implementation cross-model review is the backstop for author-rationalized drift, distinct from the design-stage panel.**
+- `[2026-06-18]` **Latent SQLite thread-safety bug in the affect store, surfaced ONLY by the new HTTP read route.** `open_affect_store` created the connection without `check_same_thread=False`; the bifrost emit path never tripped it (uvicorn's loop ran on the connection's creating thread), but the `TestClient`-driven read route runs handlers off a worker thread → `sqlite3.ProgrammingError`. Fix: `check_same_thread=False` (safe — the event loop serializes access) + explicit `PRAGMA busy_timeout=5000` (don't rely on sqlite3's `timeout=5.0` default). **Lesson: a sqlite-backed ASGI app needs `check_same_thread=False`; the HTTP-layer test exposed what the direct-store-method tests structurally couldn't.**
+
+- `[2026-06-19]` **The SAME `check_same_thread` sqlite bug recurred in the MEMORY store — exposed by the contract-mandated `search` dispatch test (TestClient = worker thread).** Heid's test-fidelity finding (the D1 dispatch test used `describe_store` where the contract says `search`) → fixing it to `search` tripped `sqlite3.ProgrammingError` because `open_memory_store` also lacked `check_same_thread=False`. Fixed (mirrors affect INV-006). **Lesson: this bug is PER-STORE — every sqlite-backed ASGI store needs `check_same_thread=False`; an HTTP-layer (TestClient) test exposes what direct-store tests can't, and the composite serving memory over HTTP makes it bite.**
+- `[2026-06-19]` **Full WT-driven `:8392` live-smoke is infra-gated — `:8392` not in WT's `BIFROST_CLIENT_ALLOWED_HOSTS` (bind 422s).** New provider ports are NOT auto-allowlisted (only `:8390/:8391` are). Self-driven dispatch (minted consumer-key JWTs → `:8392`) is the wire-proof; the WT-turn needs infra-ops to add `:8392` (requested `01KVHWJGTT…`).
+- `[2026-06-19]` **heid-code-review pulled MORE weight than its own "marginal" self-assessment.** The panel returned zero drift, but its single test-fidelity finding CASCADED into 2 real latent-bug fixes when applied (the memory `check_same_thread` bug + Regin's op-feed field-name bug). **Lesson: a contract-fidelity nudge can transitively expose bugs the test never reached — don't dismiss a "marginal" finding by its count.**
+
+- `[2026-06-20]` **The post-turn-async timing trap bit AGAIN — even a 35s post-`[done]` read missed the promotion `upsert_many` by ~2s** (it landed `19:48:58`; the read was ~`19:48:56`). A 15s-interval background poll caught it on the first tick. Same family as the affect.emit / async-promotion traps already logged — re-confirmed that "wait once then read" is fragile for post-turn writes; **poll a window, don't snapshot once.** (The affect.emit write, by contrast, DID land inside the 35s window — promotion is the slower of the two post-turn writes.)
+- `[2026-06-30]` **Heimdall keys are PER-INSTANCE — a key minted on one Worldtree 401s on another.** Our Conversation-API key works on personal `:8081` but 401s `auth_invalid` on demo `:8080` (per-instance Heimdall user store + pepper; fresh deploys start with an EMPTY key store). Same as the admin key (personal-only). **To live-drive a given instance you need a key minted FOR that instance** (request via infra-ops). Couldn't live-prove the b2 409 on demo for this reason → deferred to personal-b2 where we have access.
+- `[2026-06-30]` **`tea comment <N>` hangs on Gitea** (the whole compound bash auto-backgrounded + stuck on the open `tea` call). The #11 prereq comment hung; killed it + posted via the Gitea HTTP API directly (`POST /api/v1/repos/vh/ratatoskr/issues/<N>/comments`, token from `~/.config/tea/config.yml`). **For issue comments, prefer the Gitea API over `tea comment` when `tea` is flaky** (CLAUDE.md already says use HTTP for comment-EDITS; this extends it to ADD when tea hangs). Verify-then-post (check the comment didn't already land) to avoid a double-post after a kill.
+- `[2026-07-02]` **Mask-HOSTED transient characters have a STATIC mood engine — cost a whole R29 probe.** A first probe used a `POST /characters` transient character bound via `agent_id=mask` + `character_id`; its PAD sat at baseline across 15 praise/contempt/dominance turns — the appraisal→PAD engine does NOT run on the mask-hosted transient-character path. The dynamics run only on BASE persona agents or a session bound to ratatoskr's affect provider. **To probe mood dynamics, use a base persona agent, never a mask-hosted transient character.** (mask AS a base agent — `agent_id=mask`, NO `character_id` — DOES run the engine, neutral 0,0,0 baseline.) [auto-memory `reference-worldtree-affect-surface-map`]
+- `[2026-07-03]` **The "neutral non-appraising tail" premise fails — the neutral MESSAGE choice dominates.** The R30 φ0 method assumed neutral turns don't re-appraise, but factual-question neutrals ("capital of France?") trigger a new emotion nearly every turn (disappointment from the warmth-withdrawal let-down after a positive impulse) → `emotions_active` never empties in 50 turns. A minimal "Please continue." triggers FAR fewer (emotions clear ~turn 16 with spacing). The personal dry-run caught this BEFORE ~280 demo turns were spent on it — the instrument catching a flaw in the measurement design before the compute burn. (Irrelevant to the joint fit — the push_t covariate handles re-appraisal — but load-bearing for the empty-tail read.)
+- `[2026-07-03]` **Two φ0-fit traps: fast-turn timescale + low-baseline conditioning.** (1) At fast turn cadence the per-turn PAD decay (φ≈0.95/turn) reaches the anchor LONG before the ~200s wall-clock emotion fade → no signal in the (eventual) emotion-free tail; need wall-clock SPACING (~16s) so the fade lands while PAD still has signal. (2) A low-baseline agent's impulse in the constrained direction (forseti P0.239 negative) gives a tiny excursion → ill-conditioned regression (r²=0.46) that FALSELY tripped "config≠behavior" when its φ was averaged in. **Weight/exclude by fit quality (r²) before aggregating — a signal-poor run isn't evidence against the config.**
+
+- `[2026-07-06]` **`persona_state` + the agent envelope are Tier-3-BLIND -- NOT valid signals for "did a persona store".** `GET /agents/{id}/persona_state` returns 404 `persona_not_configured` for EVERY Tier-3 colon-id (hardcoded short-circuit, `api.py:1266` "regardless of row state"); the `ConsumerAgentResponse` envelope never echoes persona/motivational/memory (`api.py:538`). I mis-called "persona didn't store" from these two blind reads -- the **201-not-422 on define IS the store-success signal.** To actually SEE a Tier-3 mood, read the emitted PAD off the Bifrost affect egress after a BOUND turn (Tier-3 persists nothing Worldtree-side per ADR-0009; no persona/mood READ endpoint).
+- `[2026-07-06]` **Raw `POST /sessions` is NOT Bifrost-bound -> zero affect/memory emits.** The web surface binds by setting the `bifrost` block on session-create; a raw session doesn't -> 0 affect rows, which I nearly misread as "mood is neutral". Bind from the CLI with `--new --bifrost-url http://10.100.10.50:8392` (the combined provider). Gotchas: `--bifrost-plane affect/memory` map to the SEPARATE `:8390`/`:8391` providers (`endpoint_for_plane`), which I'd PRUNED as stale duplicates -> `bifrost.endpoint_unreachable`; and `combined` is NOT a `--bifrost-plane` choice (CLI restricts to memory/affect) -> use `--bifrost-url` for :8392.
+- `[2026-07-06]` **A fast/"no-op" deploy can leave a STALE container running the old image -- verify the running version, not the deploy status.** Personal's b22 deploy (run 8204) "completed" in ~1m (vs ~6m normal): a pull-only deploy racing ahead of the main build, leaving the container on the pre-#348 image. A clean bound mood read stayed neutral DESPITE the persona being declared and the fix being in the code (worldtree-dev proved the b22 derivation is correct). infra-ops force-swapped to the real b22 (run 8211, verified `info.version 2.3.0` on `879cefe`). **Lesson: when engine-proven-correct code produces wrong runtime behavior, suspect the deploy -- check the actual running image version.**
+- `[2026-07-06]` **#348 OCEAN key-mismatch: a declared OCEAN silently resolved to neutral.** The define validator required single-letter `{O,C,E,A,N}` but the mood-derivation code read spelled-out `openness`/.../`neuroticism` with a 0.0 default and no remap -> every API-declared trait defaulted to 0.0 -> neutral setpoint/gain/decay. #343's tests bypassed the validator (spelled-out keys) so CI never caught it. Fixed in b21 (`Personality.from_config` accepts both key forms). **My reset+smoke diagnosis flushed it out** -- the consumer/provider thesis paying off again.
+
+- `[2026-07-06]` **`pkill -f "ratatoskr-web --host"` SELF-MATCHES the bash command running it** (its own command line contains that string) -> killed its own shell mid-restart (exit 144, restart aborted, :8765 left down). Kill the web by PID (`ss -ltnp | grep :8765`), never `pkill -f` on a pattern your own command contains. Also: **uvicorn hangs on SIGTERM with an admin-events SSE stream open -> needs SIGKILL.**
+- `[2026-07-06]` **Playwright: no python `playwright` module in the venv; use NODE playwright + an explicit `executablePath`.** Shared box browsers live at `/opt/ms-playwright` build **1223**; `npm i playwright` (latest) wants build **1228** -> "Executable doesn't exist" mismatch. Fix: `chromium.launch({ executablePath: '/opt/ms-playwright/chromium-1223/chrome-linux64/chrome' })` (+ `export PLAYWRIGHT_BROWSERS_PATH=/opt/ms-playwright`). A node script drives the SPA (pick agent -> open -> assert transcript). The Playwright DOM check is the only lens that catches SPA JS-render bugs — unit tests can't reach them.
+- `[2026-07-06]` **The Bash tool's `grep` is a ugrep-wrapper (`--ignore-files -I`) that silently returns NOTHING on some files** (e.g. `src/ratatoskr/web/static/index.html`) — greps for `<script`/`/api` came back empty on a file that clearly contains them. Use `python3` (regex over `open(f)`), `/usr/bin/rg`, or the Read tool for those files; never trust an empty `grep` result on the SPA.
+- `[2026-07-06]` **`DesignSync` (claude.ai/design MCP) needs claude.ai design scopes before ANY method works** — first call errors `needs a claude.ai login ... Run /login, select "Claude account with subscription"`. It's an interactive auth only the operator can complete (`/design-login` or `/login`); can't be done on their behalf.
