# Persistent memory — ratatoskr _Last updated: 2026-07-10_ This file captures durable intent and supporting evidence (goals, decisions, foot-gun warnings, in-flight state) across context resets. Read it at session start; treat it as one input alongside `CLAUDE.md` and the auto-memory system, not as the single source of truth. When durable state shifts enough to warrant capture, run `/snapshot` and commit alongside the next commit per the persistent-memory commit-along rule in `CLAUDE.md`. --- ## Repo purpose Ratatoskr is a **dev-grade debug-observability TUI** for Worldtree's Conversation API. The product IS the observability surface; chat is the input mechanism. Devs run Ratatoskr against a local Worldtree to watch a turn flow through every layer of the system, side-by-side, in one terminal: agent SSE stream, persona/Vili affect dispatch, tool calls, Bifrost handshake state, admin lifecycle events, optional raw server log. Named after the squirrel that runs up and down Yggdrasil carrying messages between layers. On-the-nose Worldtree resonance (Yggdrasil = the World Tree). **Second identity (since 2026-06-14): the v1 Bifrost Tier-3 consumer/provider** — the durable persistence Worldtree writes Tier-3 agent affect (PAD/persona, `:8390`) + memory (`:8391`) into. Lives in `src/ratatoskr/provider/`, depends on `bifrost` (`provider` optional-extra), separate from the conversation-API spec pin. So ratatoskr now owns BOTH ends of the Bifrost round-trip — the lens #17 exploits. **v0.15.0+ sibling browser surface** (`ratatoskr.web`, `ratatoskr-web` console script): same five-pane debug surface over the same SSE wire, LAN-viewable. Internal-LAN trust model — `0.0.0.0`, no auth/TLS/CORS (operator direction). Disciplined regardless: transcript HTML-escapes assistant content (INV-004); upstream API key stays server-side (INV-003). ## Current state / in-flight _As of 2026-07-10:_ **NOTHING IN FLIGHT — clean checkpoint.** This cycle shipped `v0.20.7` (web-UI iteration-3) → `v0.20.8` (bifrost 1.1.0) → `v0.20.9` (PAD auto-scale), all on origin (HEAD `709d2e4`). Bound Tier-3 is fully restored on Worldtree b47/wire-v0.7 (see the `[2026-07-10]` handshake decision); the R34-v1 affect.emit verify ran GREEN (dominant_emotion non-null, `affect.full` grant verified-active); sindra is on `character-rp`/Deckard (live-confirmed). **Only pending item:** the affect-egress-reconstruction canon re-vendor, coordinated w/ worldtree-dev, gated on the brokkr use-case-segregated-render epic (non-breaking, no action until they re-engage). Details of the shipped web work below. **✅ SHIPPED — web-UI iteration-3, all three queued items (`v0.20.7`, patch, agent-discretion; 631 tests green; :8392 combined provider + :8765 web both restarted on the new code).** **(A) Design prototype iteration-3 adapted into `index.html`** (re-pulled `Ratatoskr Console.dc.html`, project `bc0b65d1-…`): (1) sparkline **grid bg** — `` in the hidden defs + a bg `` behind every relation-row spark polyline; (2) **PAD strips → per-turn Δ bars** — REMOVED the vertical polyline strip (`stripPoints`/`proj3` gone) for `padDeltas`→`deltaStrip`: a 12-cell HTML column (newest at bottom) of diverging bars offset L/R of a center line by that turn's Δ (magnitude→width, age→opacity, zero→faint center dot); head legend now "Δ/turn · last 12 · newest ↓"; (3) **mood orbit → DIMETRIC OPEN BOX** (viewBox 124×140, az35/el25, D-right/A-left-back/P-up) — ghost A×P wall (P readout) + D×A floor, `orbitProj/orbitShadowY/orbitWallPt/orbitAxisPt` projections, **JS-driven animated replay** (`orbitFrame` rebuilt per rAF by a singleton `startOrbitAnim` reading live `ORBIT_HIST`; reduced-motion → static final-state; no SMIL). Playwright-verified (dimetric frame + 17 dyn children + 21 Δ-bars + 5 grid rects; dark+light screenshots). **(B) Memory viewer SHIPPED + the 0/0 mystery ROOT-CAUSED.** New non-bifrost debug read `GET /memory/chunks?agent_id=&end_user_id=` on the combined `:8392` provider (`RatatoskrMemoryStore.list_chunks` + `count_chunks` + shared `add_memory_read_route`, wired into `build_memory_provider_app` + `combined.py`; **end_user STRICT, agent_id LENIENT** so `{end_user}`-only WT chunks aren't hidden; returns `{chunks,count,total}`, empty=200 not 404) → web proxy `GET /api/memory/chunks` (server-supplied end_user, new `RATATOSKR_MEMORY_READ_URL` env, default `:8391`, set to `:8392` in env.sh) → a live-polling MEMORY console pane (`loadMemory`/`renderMemory`/`setMemHead`, polled on open + post-turn). **ROOT CAUSE of the operator's 0/0** (settled via a bound 6-turn probe + op-feed): the Bifrost memory plane **binds and grants fine** (handshake `caps_requested:[affect,memory]` → `caps_granted:[memory,affect]`), but **sindra dispatches ZERO memory ops** (not even a recall search) — her reset-clean agent definition has **no `memory:{}` block**, so Worldtree never runs the memory pipeline for her. NOT a bind-grant failure, NOT promotion-timing. **PROVEN end-to-end** with a throwaway memory-enabled `ratatoskr:memprobe` (defined with `memory:{}`): 6 bound turns → 6 `memory.search` recalls + **4 `memory.upsert_many` → 4 real chunks in `memory.db`** → the pane renders all 4 (content·scope·origin·revision) live. **⚠ LEFTOVER debug state (operator chose KEEP):** `ratatoskr:memprobe` agent on personal WT + test chunks (scope `{end_user:ratatoskr-tui}`) sit in the live `memory.db` — harmless (make the pane show real data); `scripts/reset-sindra-stores.sh` or `DELETE /agents/ratatoskr:memprobe` clears them. **✅ SINDRA MEMORY FIXED (operator-approved, 2026-07-07):** DELETE+redefined her WITH `memory:{}` (prompt byte-identical, `role=character`, OCEAN `{O:0.8,C:0.3,E:0.9,A:0.4,N:0.2}` preserved — pleasure-verified vs the mood-fix setpoint 0.418; backup at scratchpad `sindra_backup.json`). PROVEN: she went from ZERO memory ops → full recall (Orion fact @ cosine 0.988) **+ promotion** (her own "systems architect" fact upserted; store grew to 9→11 chunks). Reusable redefine script: scratchpad `redefine_sindra.sh`. Note: DELETE+redefine is the ONLY path (persona+memory immutable post-define); the destructive `DELETE` tripped the harness auto-mode guard → operator ran it via `!`. **(C) Markdown pass-2 SHIPPED** — `markdownSafe` extended: GFM pipe tables (`mdTable`, alignment colons), indentation-nested lists (stack of `
