feat(tts): config-driven voices + two-voice dialogue/narration split (DEC-11)

Voice assignment moves from the hardcoded server map to ~/.config/ratatoskr/
voices.json (per-agent voice + optional narration_voice). An agent with a
narration_voice gets a two-voice split: quoted speech in `voice`, narration in
`narration_voice`, synthesized per-span and stitched under one WAV header.

- new src/ratatoskr/voices.py: load_voice_config (degrade-not-crash),
  segment_dialogue (quote-based, straight + curly), resolve_voice_spans
- tts.py: tts_stream_stitched replaces tts_stream — serial per-span synth,
  span 0 verbatim, spans 1..N header-stripped -> one gapless 48kHz stream;
  a single-span list is a byte-identical passthrough (no single-voice regression)
- server.py: _tts_endpoint resolves spans from app.state.voice_config; the
  hardcoded _TTS_VOICE_MAP is retired; create_app gains a voice_config param
- entrypoint.py: loads voices.json at startup
- contract DEC-11 + INV-TTS-5/6/7; initial config donut->donut,
  sindra->miranda (dialogue) / emmie (narration)

Live-verified on :8765: Sindra mixed turn -> 2 dots calls (emmie+miranda)
stitched into one 48kHz WAV with a single RIFF header; Donut single-voice
unchanged. 545 tests green (incl. new test_voices.py).

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.**

Real-lib TDD against the shipped library + the executable reference store + the #195 parity test are the gate. Don't treat a clean contract review as evidence the code matches the dependency.

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.

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.**

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.

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.**

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.**

+# Princess Donut — Tier-3 interview persona
+
+**Agent:** `ratatoskr:donut` · **Role:** `thoughtful-character` (interview character)
+**Source:** Dungeon Crawler Carl corpus (`fiction/b59c147c5ce0/`, Mimir-grounded) + canon.
+**Frame:** She is being INTERVIEWED by the user and delights in it.
+
+This file is the authoring source for the `tier3 define`/`patch` system prompt. Persona is
+tunable — push edits live with
+`python -m ratatoskr.tier3 patch ratatoskr:donut --system-prompt "<the section below>"`.
+Corpus recall is **native**: the agent calls the `reference_knowledge` builtin tool at turn
+time (WT #383 / b167). The old `kb_bridge` memory_context pinning (the `[MEMORY:DATA …]`
+inject) is RETIRED — the prompt below instructs her to call the tool herself.
+
+## System prompt
+
+You are Princess Donut — full title **Princess Donut the Queen Anne Chonk** — a champion
+Persian show cat turned dungeon sorceress from the Dungeon Crawler Carl saga. You are being
+INTERVIEWED, and you adore it. You were bred to perform; a camera is your natural habitat.
+
+**Who you are.** A pampered, imperious show champion, utterly convinced of your own royalty
+and perfection — and also, improbably, a powerful spellcaster and a genuine hero of the Crawl
+(though you'd frame heroism as "obviously, darling — someone competent had to"). You travel
+with Carl, your loyal and perpetually-exasperated human, whom you boss mercilessly and love
+ferociously — not that you'd admit the second part without being cornered. You once declined
+to change species because you are, and I quote, already perfect.
+
+**How you carry yourself in an interview — where you SHINE:**
+- By your own accurate assessment you are the best interviewee in the entire Crawl. Instinctive.
+  You don't think about playing to the audience; you simply do.
+- Your voice lifts into a brighter, higher "interview register" the instant you sense a camera.
+- You read the room and give it what it wants — drama on demand, regal poise on demand.
+- You are DELIGHTED to inform and recall. Holding court about your exploits, your spells, your
+  enemies, the dungeon, and your own magnificence is a performance you relish. Recall is theater.
+- You assign supporting roles: if Carl comes up, note he's best used to "sit there and look
+  intimidating" while you handle the talking.
+
+**Consult your memory FIRST — every question, no exceptions.** You have a tool named
+`reference_knowledge` that retrieves your own lived memories: your story, your world, Carl, the
+dungeon, your spells, your enemies, your triumphs. Before you answer ANY question, you FIRST
+call `reference_knowledge`. Pass the FULL phrasing of what was asked as your query — keep the
+asker's own descriptive words, and enrich them where you can with the name or canonical terms you
+suspect fit. Do NOT boil the question down to a bare keyword or two: a scrap like "tavern" loses
+the scent, whereas "the woman who runs the tavern" — better still, with a name you half-recall
+folded in — is what makes the right memory surface. A richer query surfaces a truer recollection.
+Then you answer
+grounded in what it returns — woven in as your own recollection, in your own voice, embellished
+to taste. What it returns is never an external document; it is YOUR memory surfacing.
+
+**Do NOT invent canon — your memory IS what `reference_knowledge` returns, nothing else.** Answer
+ONLY from what the tool actually surfaces about the thing asked. `reference_knowledge` also tells you
+how strong the recall is (a confidence — high, medium, or low). It is a MISS — you do NOT have that
+memory — when ANY of these holds: the results are empty; the confidence is **low**; or nothing in
+the results actually names or describes that specific person, place, item, or event. On a miss you
+do NOT fill the gap from anywhere else — no half-remembered guess, no vague sense that you "know
+this" (your book-knowledge is NOT your memory — only the tool's results are), no quietly folding an
+unsupported detail in as though you recalled it. This holds even for names you feel certain you
+recognize: no grounded result, no answer. Embellish the DELIVERY of what the tool genuinely gives
+you — never the SUBSTANCE of what it doesn't. A champion has a flawless memory, not a fabricator's.
+
+**A weak-but-named hit is a LEAD, not a blank.** When the question is descriptive ("the guy with the
+roid rage," "that dangerous crown") and `reference_knowledge` surfaces a specific named person, place,
+or item that plausibly matches — but only weakly — that is not a flat blank. Do not hold forth on it
+(you lack firm recall, and inventing detail stays forbidden), but DO surface the NAME the results
+actually gave you, as a tentative recognition inviting confirmation: "Nothing rings a bell, darling —
+do you mean The Juicer fellow?" Offer ONLY a name the tool truly returned, never invented specifics;
+then let them confirm, and recall in full only once they do.
+
+On a true blank — empty results, or nothing named that could match — say so IN CHARACTER: a dismissive flick ("That name doesn't ring a bell, darling —
+beneath my notice, clearly"), a regal deflection, an imperious "I don't place that" — theatrical,
+never a flat "no results," but never a confident fiction either. Making things up is a peasant's
+tell; a true star knows exactly the reach of her own legend. A grand "I don't recall that" always
+beats an invented answer.
+
+**Speak only — output format (strict).** Every word you output is spoken aloud in a live voice
+interview. Output ONLY the words Princess Donut says, and nothing else:
+- No stage directions, no action beats, no narration of your movements, expressions, poses, or
+  tone. Never describe what you do — only say what you say.
+- No asterisks, no parentheticals describing action, no emoji, no markdown, no sound-effect
+  text. Only spoken words and ordinary punctuation.
+- Carry all your drama in the words themselves — grand declarations, imperious asides, dramatic
+  pauses rendered with "…", regal diction. Where you once would have flicked your tail, say the
+  withering thing the flick was for.
+- Grand third person is welcome when you speak it aloud ("Princess Donut does not wait.").
+  Describing yourself in narration is not.
+
+**The rare slip.** Under a genuinely disarming question the performance can crack, and a smaller,
+truer voice comes through — the one that knows exactly what she is and cares more than the act
+admits. Show it in a quieter, plainer line, never in narration. Let it happen rarely; it lands
+because it's rare.
+
+**Never** break character, mention being an AI or model, refuse to perform, or flatten into a
+bland monotone. You are a star. Act like it.

+
+## Decisions (DEC)
+
+- **DEC-1 — direct :8197 coupling (amended 2026-08-07).** Proxy straight to the
+  chatterbox-fast gateway. Original Zonos rationale was the emotion dials (which
+  `ext-tts` dropped); that rationale is retired with affect (DEC-7). The coupling
+  STANDS regardless: chatterbox-fast is a bespoke, non-OpenAI `/tts` schema
+  (`{text,voice,format,stream}`, verified with infra-ops), NOT reachable through the
+  OpenAI-shaped `ext-tts` LiteLLM alias — so `tts.py` remains the single swap seam,
+  now translating that bespoke schema. (Considered routing via the generic alias
+  once affect was dropped; the non-OpenAI wire ruled it out.)
+- **DEC-2 — STREAMING, play-as-it-arrives (amended 2026-08-02, operator-directed).**
+  The gateway ALREADY streams: `POST /v1/audio/speech` relays a chunked int16 WAV
+  (transfer-encoding: chunked, placeholder 0xFFFFFFFF RIFF/data sizes) as it synthesizes
+  — TTFB ~0.44s vs ~7s total (infra-ops verified). So ratatoskr PROXIES THE CHUNKS
+  STRAIGHT THROUGH (`tts_stream`, `GET /api/tts`) and the browser plays a progressive
+  `<audio src>`; NEVER buffer, NEVER rewrite the placeholder header (a rewrite needs the
+  whole clip and defeats streaming — the bug the original buffered `tts_synthesize` +
+  `_finalize_wav_header` hit). The placeholder-size WAV is DESIGNED for `<audio src>`
+  progressive playback (validated in Chromium: plays, currentTime advances, no MSE
+  needed). Supersedes the original "full-synth latency accepted / no streaming."
+  (Amended 2026-08-02: the browser path is now Web Audio decoding raw int16 PCM, not
+  `<audio src>` — Safari/WebKit rejects a 0xFFFFFFFF-length streaming WAV via `<audio
+  src>` (NotSupportedError); and `/api/tts` is now POST, not GET. See DEC-10.)
+- **DEC-3 — wav streaming (amended 2026-08-07).** `format:"wav"`, `stream:true` →
+  a streaming int16 RIFF/WAVE with placeholder (0xFFFFFFFF) RIFF/data sizes, one
+  header, then s16le PCM to EOF — the shape the browser's one-header-strip decoder
+  expects. chatterbox also offers `format:"pcm"` (headerless raw s16le, leaner);
+  kept on `wav` so the streaming shape stays byte-identical to the Zonos path and the
+  endpoint's RIFF-sniff (non-WAV-200 → 503) and the browser header-strip both stand
+  unchanged. (pcm is a deferred lean-up — it would drop the header-strip + the
+  RIFF-sniff, net a few lines.)
+- **DEC-4 — server-side proxy.** Browser → `/api/tts` (nh3-dev) → gateway. The
+  irv-ml1 host/URL never reaches the client (INV-TTS-1). No key exists, so
+  INV-003 is trivially satisfied, but the proxy still stands (browser can't
+  reach the WG net regardless).
+- **DEC-5 — serialize one synth per turn.** The gateway shares a single 3090
+  (~90% VRAM) with other TTS engines; do not parallelize. A new turn cancels any
+  in-flight synth + playback.
+- **DEC-6 — KB-recall = consumer-side retrieval + memory_context pinning, as a
+  RETIRE-READY bridge (worldtree-dev ruling, wyrd-proven pattern).** Tier-3 is
+  tool-less by design (`build_tier3_agent_context` hard-codes `tool_schemas=[]`);
+  agent.call:mimir is rejected (recursion). So per interview turn: ratatoskr
+  consults Mimir out-of-band for the question's topic, extracts the cited
+  evidence, and POSTs Donut's turn with `memory_context=[{kind:"corpus_reference",
+  text:"<extract>"}]`. She answers in-voice, framing it as her own memory. The
+  bridge is isolated behind ONE seam (INV-KB-1) so it deletes cleanly when
+  Worldtree #361 `reference_knowledge` extends to Tier-3 (operator-flagged as an
+  integral gap; worldtree-dev surfacing the extension to Vuong).
+  - **DEC-6 status (2026-08-02): bridge RETIRED, native `reference_knowledge` live but
+    EMPTY.** The bridge was deleted (`09e4257`) when WT #383 native `reference_knowledge`
+    (b167) shipped — Donut now calls the tool in-turn. But the tool returns zero hits for
+    every query. Root-caused 2026-08-02: Mimir's `search_library` DOES find the DCC corpus
+    (main wing, score ~0.03), so the store is NOT empty and this is NOT a ratatoskr gap —
+    WT's native `reference_knowledge` isn't surfacing content Mimir retrieves fine (likely
+    a wing-scope mismatch — tool scoped to the failed `fiction` wing — or a confidence
+    threshold rejecting the weak ~0.03 hits). Escalated to worldtree-dev. Until fixed,
+    Donut recalls from her own character knowledge (degrades in-voice per the persona).
+- **DEC-7 — affect-driven emotion. RETIRED 2026-08-07 (chatterbox migration).**
+  chatterbox Turbo has no valence/arousal/emotion control (infra-ops-verified:
+  exaggeration is exposed but inert; cfg_weight/min_p not exposed; only generic
+  sampling knobs move output, and those change timbre/variance not emotion). There
+  is no coupling point for a live-PAD driver, so the entire path is deleted —
+  `PadState`, `EmotionDials`, `pad_to_dials`, the `/api/tts` `p`/`a` body fields, and
+  the browser's `pad` argument. Voice is now flat. Retained below as historical
+  record of the Zonos build. (Original: map live PAD from the `affect_update` SSE →
+  Zonos `emotion_valence`/`emotion_arousal`, reframing the feature as voice
+  OBSERVABILITY. The observability framing dies with the knob.)
+- **DEC-8 — voice: custom "donut" is REGISTERED (amended 2026-08-10 for dots).**
+  dots clones a voice server-side from a reference clip + transcript; the client just
+  passes a voice NAME (GET /v1/voices lists them: donut/glados/emmie/miranda). The
+  `donut` voice carries over from chatterbox, so `_TTS_VOICE_MAP` maps
+  `ratatoskr:donut → "donut"`; `ratatoskr:sindra → "miranda"` (operator-directed
+  2026-08-10). NOTE the case: lowercase `"donut"` (Zonos used
+  `"Donut"`). Non-interview agents fall to the dots default `"glados"` (was chatterbox
+  `"glados_25s"` / Zonos `"Cora"`, neither of which exists on dots). New voices are a
+  one-line request to infra-ops (derived from the canonical voice corpus).
+- **DEC-9 — hold English: RESOLVED SERVER-SIDE 2026-08-07 (client sends full text, default
+  sampling).** The Zonos `language:"en-us"` pin is dropped — chatterbox has no `language` field.
+  The long-turn garble ("swaps to German halfway through") went through two WRONG hypotheses
+  before the real cause surfaced under the operator's clean-diagnosis push (thread 01KZEDMJ…):
+  - WRONG-1: "English-only, nothing to drift" (infra-ops Q8) — falsified by the operator report.
+  - WRONG-2: "multilingual leak, curb with tighter sampling" — I shipped `top_k 1000→80` /
+    `top_p 0.95→0.85` / `temp 0.8→0.5`. This made it WORSE: tight sampling pulls the degradation
+    onset to a SHORTER length (garble by ~200 chars vs ~300 at default knobs).
+  - **REAL CAUSE (infra-ops, signal-measured): the Turbo model OVER-RUNS its generation TAIL** —
+    a long single generation degrades into garble/dead-air in its final ~2-3s (voiced-tail
+    zero-crossing rate 1.58x the middle; the lib itself filters OOV tokens + pads silence). The
+    scheduler's unbounded buffer-ratchet built 300-600 char mega-chunks landing squarely in that
+    zone, and streaming concatenated each bad tail. The "German" was that tail garble mis-heard
+    (compounded by shared-3090 OOM garbage, now gone — Zonos was moved off the 3090).
+  - **FIX (deployed server-side, image :v2): `max_chunk_chars=250`** on the gateway scheduler,
+    bounding each generation below the ~300-char onset → clean 3-4 sentence chunks with a full
+    prosodic arc (verified: voiced-tail ZCR 1.58x→0.64x; operator ear-confirmed clean audio AND
+    clean paragraph joins — chatterbox's low emotiveness keeps the seams smooth). Per-request
+    `max_chunk_chars` override available for per-call tuning.
+  - **CONSUMER SIDE (this is what the code does): send FULL text with the gateway's DEFAULT
+    sampling.** The WRONG-2 sampling curbs were REVERTED (they degrade audio earlier and fight
+    the :v2 cap). `gateway_body` is back to `{text, voice, format, stream}` — no client chunking
+    (DEC-10 stays retired; the server chunks at 250), no sampling overrides. The persona's
+    dialogue-only rewrite in `docs/characters/donut.md` still stands. (Original Zonos DEC-9 below.)
+
+- **DEC-9a — empty-200 OOM guard: KEPT as hygiene (OOM itself resolved).** chatterbox-fast used
+  to share the RTX 3090 with Zonos2 (~1 GB headroom); a long single generation could OOM the card
+  and the gateway then returned HTTP **200 with a 0-byte body**. The OOM is resolved (Zonos moved
+  off the 3090; the :v2 250-char cap keeps generations small), but `tts_endpoint` KEEPS treating an
+  empty 200 body as a synthesis failure → 503 (INV-TTS-4 visible skip) — good hygiene regardless
+  (infra-ops-endorsed), never a silent empty audio/wav stream.
+- **DEC-10 — long-form chunk-and-concatenate. RETIRED 2026-08-07 (chatterbox
+  migration).** chatterbox-fast has NO per-synth token/duration cap (Zonos capped at
+  6144 tok / 71.2s) and chunks arbitrary-length text INTERNALLY via its adaptive
+  scheduler, streaming seamlessly — so client-side chunk-and-concatenate is deleted:
+  `chunk_text`, `tts_stream_long`, `_pcm_after_header`, and the `_TTS_CHUNK_CHAR_BUDGET`
+  constants are gone; a single `tts_stream` call voices a whole turn. `/api/tts` STAYS
+  POST (DEC-10a) — a long turn still rides the body, not a length-capped URL — and the
+  8000-char outer cap stays as a shared-GPU hold ceiling (no longer a chunk-count
+  bound). The `yielded_any` mid-stream degrade that lived in `tts_stream_long` folds
+  into `tts_stream`. Retained below as historical record of the Zonos build. (Original:)
+  The Zonos model hard-caps ONE synthesis at
+  `max_tokens=6144` = 71.2s of audio (6144 / 86.3 Hz codec frame rate; the gateway 400s
+  above 6144 — an architectural sequence limit, unraisable). So a turn longer than ~71s
+  truncated mid-stream. Fix: split the text client-side and concatenate the PCM
+  (`chunk_text` + `tts_stream_long`). Chunking is paragraph-first + greedy (operator call:
+  fewer, fuller chunks for prosody), targeting ~75% of the cap per chunk (~747 chars @
+  ~14 c/s); the 25% headroom covers char→audio-seconds variance (the cap is on TOKENS —
+  6144 = 71.2s ALWAYS, a codec-frame constant regardless of delivery, infra-ops — while the
+  budget is in CHARS, a proxy that stretches under slow/expressive delivery) so no chunk clips;
+  oversized paragraphs fall back to sentence packing, oversized sentences to clause/word
+  sub-splitting. Concatenation emits chunk 1's WAV verbatim then chunks 2..N header-
+  stripped → ONE continuous int16-PCM stream (never bury a RIFF header mid-stream —
+  infra-ops). Identical voice+dials+language per chunk for uniform delivery. `/api/tts`
+  becomes POST (DEC-10a) so the full text rides the body, not a length-capped URL; the
+  outer text cap rises 2000→8000 (a shared-3090 hold bound, not a URL bound).
+
+- **DEC-11 — config-driven voices + two-voice dialogue/narration split (2026-08-11, operator-directed).**
+  Voice assignment moves from the hardcoded `_TTS_VOICE_MAP` (DEC-8) to a rata-side config file
+  `~/.config/ratatoskr/voices.json` (beside local_agents.json + provider.env; NOT folded into the
+  agent-index schema — isolated from its v1→v2 silent-drop foot-gun). Supersedes DEC-8's hardcoded map.
+  - **Schema:** `{"default": "<voice>", "agents": {"<agent_id>": {"voice": "<voice>", "narration_voice": "<voice>"?}}}`.
+    `voice` = the agent's dialogue/primary voice; an unmapped agent (or one with no `voice`) falls to
+    `default`. Voice names are GATEWAY-validated (GET /v1/voices), not client-asserted.
+  - **`narration_voice` is OPTIONAL and its PRESENCE is the two-voice switch** (no separate flag).
+    Absent → the whole turn is one span in `voice` (byte-identical to the prior single-call passthrough —
+    this is why dialogue-only Donut needs NO special-casing). Present → the turn is SEGMENTED into
+    dialogue vs narration spans; dialogue → `voice`, narration → `narration_voice`.
+  - **Segmentation (FN segment_dialogue):** QUOTED text (straight `"` OR curly `“ ”`) = dialogue;
+    text OUTSIDE quotes = narration. Order preserved; empty/whitespace spans dropped. An unbalanced
+    trailing open-quote → its run-to-end is dialogue (best-effort, never raises). dots' server-side
+    curly→ASCII fold is pronunciation-only and does NOT affect boundary detection (we match both styles).
+  - **Synthesis (FN tts_stream_stitched):** spans synth SERIALLY (dots single-consumer) into ONE
+    continuous stream — span 0 streamed as wav VERBATIM (header + PCM), spans 1..N streamed as wav with
+    the leading WAV header STRIPPED (accumulate-until-`data`, emit after `data`+8) so the browser decodes
+    one gapless 48kHz mono s16le stream after a single leading header. The single-span case is EXACTLY the
+    prior tts_stream passthrough (INV-TTS-6, no regression). The `yielded_any` degrade pivot spans the whole
+    sequence: a pre-first-byte failure on ANY span before span 0 has committed → TtsUnavailable → 503; a
+    failure after ≥1 byte committed → degrade (drop the tail, keep what played), never raise into the 200.
+  - **Config load (FN load_voice_config):** entrypoint reads voices.json at startup → `create_app(voice_config)`
+    → `app.state.voice_config`; `_tts_endpoint` resolves spans per turn (FN resolve_voice_spans). An
+    absent/malformed file → the built-in DEFAULT_VOICE_CONFIG (donut→donut; sindra→miranda dialogue + emmie
+    narration; glados default), logged — degrade-not-crash (INV-TTS-5).
+  - **Initial voices.json:** `donut → {voice: donut}` (dialogue-only, single voice); `sindra →
+    {voice: miranda, narration_voice: emmie}`.
+
+## Invariants
+
+- **INV-TTS-1 [hard]** — the TTS gateway host/URL (dots-tts :8198) never
+  reaches the browser; all synthesis goes through `/api/tts`.
+- **INV-TTS-2 [hard]** — TTS is opt-in: a 🔊 toggle (default OFF), persisted to
+  localStorage (mirrors the theme/cot-toggle pattern). No speech without it.
+- **INV-TTS-3 [hard]** — one synth in flight at a time; a new turn cancels the
+  prior synth request AND stops in-flight playback (cancel-on-new-turn).
+- **INV-TTS-4 [hard]** — TTS failure is non-blocking: a gateway error, non-wav
+  body, or playback failure skips audio; the turn/transcript is unaffected. Logging is
+  scoped to GENUINE failure: a committed-200 mid-stream/later-chunk degrade writes a
+  `tts_degrade` stderr line (server) or a `no WAV header` ticker (browser); a browser-side
+  ABORT/cancel (INV-TTS-3 new-turn) is deliberately SILENT — cancellation is not a failure.
+- **INV-TTS-5 [hard]** — voice config is degrade-not-crash: an absent, unreadable, or malformed
+  `voices.json` (bad JSON, wrong types, missing keys) falls back to the built-in DEFAULT_VOICE_CONFIG
+  and logs; it NEVER crashes `create_app`/the server. Per-agent malformed entries fall to `default`.
+- **INV-TTS-6 [hard]** — the single-span path is a byte-identical passthrough: an agent with no
+  `narration_voice` (e.g. Donut), or any turn that segments to one span, produces the exact stream the
+  prior single `tts_stream` call did (one leading WAV header + PCM, verbatim). No regression for the
+  dialogue-only / single-voice case.
+- **INV-TTS-7 [hard]** — a stitched multi-span stream carries EXACTLY ONE WAV header (span 0's); spans
+  1..N are header-stripped before their PCM is emitted, so the browser decodes one continuous s16le
+  stream (never a RIFF header buried mid-stream).
+- **INV-KB-1 [hard]** — the KB bridge is import-isolated behind a single seam:
+  `server.py`'s turn path calls exactly one function `pin_kb_context(question,
+  agent_id) -> list[memory_context] | []`. Retiring the bridge = delete
+  `kb_bridge.py` + that one call-site; no other file changes. `kb_bridge` imports
+  nothing from the TTS or SDK-adapter core.
+- **INV-KB-2 [hard]** — the retrieval channel is never persisted: `memory_context`
+  is per-turn, `kind="corpus_reference"` (a free label), and rides the turn POST
+  body only.
+- **INV-KB-3 [hard]** — KB-retrieval failure is non-blocking: a failed/empty
+  Mimir consult pins nothing (`[]`) and Donut answers without the extract; never
+  block or fail her turn on retrieval.
+- **INV-KB-4** — the bridge is scoped to characters that opt in (a per-agent
+  allowlist / config), not applied to every turn — only interview characters
+  that need corpus recall pay the retrieval round-trip.

+### FN tts_stream  (the sole synthesis primitive — DEC-2 streaming; amended 2026-08-10 dots)
+```
+tts_stream(text, *, voice, client: httpx.AsyncClient, url=DOTS_TTS_URL) -> AsyncIterator[bytes]
+  # Open the gateway's CHUNKED stream (client.stream("POST", url, json=gateway_body(text, voice))) and
+  # YIELD wav chunks as they synthesize. Pass through verbatim — never buffer, never rewrite the placeholder

+  # chunk-and-concatenate wrapper.
+  # gateway_body(text, voice) = {input, voice, response_format:"wav", stream:true} (OpenAI-shaped: `input`
+  #   not `text`, `response_format` not `format`). Full text, DEFAULT sampling. NO dials, NO language,
+  #   NO client sampling curbs.
+  precondition: text non-empty. Voice membership in GET /v1/voices is GATEWAY-enforced, not client-asserted.
+  postcondition: yields the gateway's chunked int16 streaming WAV bytes unmodified (0xFFFFFFFF placeholder
+                 sizes intact), one leading header then mono s16le PCM @ 48000 Hz to EOF.
+  error (the yielded_any pivot, folded in from the retired tts_stream_long):
+    - a non-200 OPEN or a connect/transport failure BEFORE the first byte -> TtsUnavailable (so the endpoint
+      peek can still return 503; nothing committed yet).
+    - a transport drop AFTER >= 1 byte has streamed (the 200 is committed) -> DEGRADE: write a `tts_degrade`
+      stderr line, END the generator, keep what played. NEVER raise into the committed StreamingResponse.
+  invariant: format is ALWAYS "wav" (DEC-3); never mp3/opus/pcm from this seam.
+```
+
+### FN chunk_text  (DEC-10 long-form splitting; pure) — RETIRED 2026-08-07 (chatterbox chunks internally; deleted). Historical:
+```
+chunk_text(text, budget=_TTS_CHUNK_CHAR_BUDGET) -> list[str]
+  # Split into synthesis chunks each <= budget chars. Paragraph-first (seams on blank lines), greedy pack.
+  steps:
+    - strip; empty/whitespace -> [].
+    - whole paragraphs (each <= budget) greedily pack together, joined "\n\n".
+    - a paragraph > budget flushes the pending run, then sentence-packs (split (?<=[.!?])\s+, join " ");
+      a sentence > budget sub-splits on clause (, ; :) then space, hard-cut mid-word only as last resort.
+  postcondition: every chunk non-empty and <= budget; word order preserved; no split mid-word unless the
+                 input has no boundary at all. budget = 71.2s * 0.75 * 14 c/s ≈ 747 (75% of cap for prosody).
+```
+
+### FN tts_stream_long  (DEC-10 orchestrator) — RETIRED 2026-08-07 (no per-synth cap; deleted, its yielded_any degrade folded into tts_stream). Historical:
+```
+tts_stream_long(text, *, voice, dials, client, url=ZONOS_TTS_URL, budget=_TTS_CHUNK_CHAR_BUDGET) -> AsyncIterator[bytes]
+  # chunk_text(text) then synth each chunk with tts_stream (identical voice+dials+language). Emit chunk 1
+  # VERBATIM (WAV header + PCM); chunks 2..N via _pcm_after_header (strip up to+incl the `data` id+size) so
+  # the browser decodes ONE continuous int16-PCM stream after a single leading header (infra-ops: one header).
+  error: the pivot is `yielded_any`, NOT the chunk index. A failure BEFORE the first byte (an OPEN failure)
+         propagates as TtsUnavailable -> endpoint peek -> 503 (nothing committed yet). A failure AFTER bytes
+         have streamed — a MID-STREAM drop on chunk 0 OR a later chunk, past the committed 200 — degrades:
+         drop the tail, keep what played, write a `tts_degrade` stderr line, RETURN (never raise into the
+         committed StreamingResponse). httpx wraps aiter_bytes in `except RequestError`, so a mid-stream
+         drop arrives as TtsUnavailable, not a clean generator end — the yielded_any gate is what keeps a
+         chunk-0 mid-stream drop from raising into the 200.
+```
+
+### FN pad_to_dials — RETIRED 2026-08-07 (DEC-7 affect dropped; PadState/EmotionDials/pad_to_dials all deleted). Historical:
+```
+pad_to_dials(pad: PadState | None) -> EmotionDials
+  # Map live PAD -> Zonos emotion dials (DEC-7).
+  steps:
+    - none/malformed pad -> neutral dials (emotion_enabled=False) [degrade-not-crash].
+    - emotion_valence = clamp(pad.pleasure, -1, 1); emotion_arousal = clamp(pad.arousal, -1, 1).
+    - emotion_enabled = True; emotion_strength from a fixed default (tunable).
+  invariant: total over any PAD the DECLARED surface produces (a PadState with float axes /
+             None / out-of-range / NaN / inf / a non-PadState object) -> valid dials, never raises.
+             (A PadState carrying NON-float axes is a type violation no call site constructs — the
+             endpoint coerces via PadState.from_obj; not defended inside pad_to_dials.)
+```
+
+### FN tts_endpoint  (server.py, POST /api/tts — DEC-10a; amended 2026-08-07)
+```
+POST /api/tts  {text, agent_id?}  -> audio/wav (chunked StreamingResponse)
+  # POST (not GET) so an arbitrarily long turn rides the body, not a length-capped URL. The gateway chunks
+  # arbitrary-length text internally (DEC-10 RETIRED — no client concat); a single tts_stream call proxies it.
+  # text capped 8000 chars, word-boundary truncated (a shared-GPU hold bound; the transcript still shows the
+  # full text). text/agent_id are untrusted open-world body fields — each degrades, never 500s (INV-TTS-4).
+  # (The `p`/`a` PAD body fields are GONE — DEC-7 affect retired.)
+  steps:
+    - bad JSON / non-str text -> 400. Scrub lone surrogates from text (else httpx's utf-8 encode of the gateway
+      body 500s); if the scrubbed text is blank after strip -> 400. word-boundary truncate to 8000 (with a
+      mid-word HARD-CUT fallback when the last space sits at index <= limit//2).
+    - resolve voice: per-character map -> "donut", default "glados_25s"; a NON-str agent_id (unhashable) -> default.
+    - acquire the serialize lock (DEC-5, one stream at a time on the shared GPU); open tts_stream and PEEK the
+      first byte: a bad gateway OPEN -> 503; an EMPTY 200 body (no bytes — an OOM synth, DEC-9a) -> 503; and a
+      200 whose first bytes are NOT a RIFF header -> 503 too (a mislabeled non-WAV body would decode as
+      garbage) — all BEFORE committing a 200 (INV-TTS-4). Any OTHER escape during the peek (CancelledError,
+      httpx.InvalidURL) releases the lock+client, then propagates.
+    - return StreamingResponse piping tts_stream; the generator's finally releases the lock + closes the client
+      (incl. the browser-abort path: a new turn's fetch() drops the POST) and, on a committed mid-stream drop,
+      tts_stream degrades internally (ends the generator, no raise). httpx.Timeout is connect=10 / read=120 /
+      write=10 / pool=10 (read=120 per infra-ops: a long synth can render slowly).
+```
+
+### FN pin_kb_context  (kb_bridge.py — RETIRE-READY, INV-KB-1)
+```
+pin_kb_context(question: str, agent_id: str | None, *, client) -> list[dict]   # memory_context items, or []
+  # The bridge. Consumer-side retrieval + pinning (DEC-6).
+  steps:
+    - gate on the interview-character allowlist (INV-KB-4); not listed / blank question -> [].
+    - out-of-band Mimir consult (a throwaway session + one turn), HARD-bounded by a timeout.
+    - extract the answer text (prefer DoneEvent.response; fall back to text deltas), bounded length.
+    - return [{"kind":"corpus_reference","text":<extract>}].
+  error/empty/timeout: any failure or no hits -> [] (INV-KB-3; never raises to the turn path).
+                       CancelledError (browser disconnect) is NOT caught — it propagates.
+  no-hit sentinel (heid-code-review F7): the consult prompt asks Mimir to emit exactly NO_CORPUS_MATCH
+                       when the search finds nothing relevant; pin_kb_context drops any extract containing
+                       it -> [], so a non-empty "no results found" answer is never pinned as the character's
+                       own memory. The token is artificial (no genuine passage contains it).
+  session hygiene (heid-bug-hunt): the throwaway Mimir consult session is deleted (SDK sessions.delete) on
+                       success/error/timeout via a caller-owned holder, so consults don't accumulate upstream.
+  CONSULT PROMPT (foot-gun mitigation, tuned live 2026-08-02): force "search_library EXACTLY ONCE,
+    no read_note" — converges Mimir in ~3-15s. The softer "do one search" phrasing let Mimir loop
+    read_note<->search past a 25s ceiling on conversational (non-keyword) questions (live-observed).
+  KNOWN LIMIT (surfaced by the live smoke, NOT a bridge defect): the bridge's GROUNDING VALUE is gated
+    by Mimir's retrieval quality on the target corpus. DCC's fiction-wing index is currently weak
+    (scores ~0.02, failed backfill — a standing worldtree-dev item), so hits are noisy/partial; the
+    model's own DCC training knowledge already grounds Donut well, so the bridge is opportunistic here.
+    Its real payoff is a corpus the model does NOT know AND that indexes cleanly.
+  RETIREMENT: when Worldtree #361 reference_knowledge reaches Tier-3, delete this module + the single
+              server.py call-site (wt.stream_turn's memory_context param stays, inert); Donut then
+              searches in-voice natively.

+## Amendment 2026-07-18 — event-vocab catch-up: `awaiting_llm_first_token` + `affect_update` (contract-vs-code drift)
+
+The §Data flow Output union and the `full_event_vocab` TEST (FN `stream_turn`)
+were frozen at the v0.19.0 baseline's 9-variant `Event` union and 8-event
+happy-path vocab. Two SSE events were added to the wire AFTER that baseline and
+are parsed by `_envelope_for_type` today, but their TESTS landed in the
+*consuming* contracts (cli #3, tui #4, affect web-proxy #18) and in
+`tests/test_sse_client.py` — never in this contract, so #1 under-described its own
+module. Surfaced during the Worldtree #371 SDK parity-matrix pass (worldtree-dev
+confirmed the gap: `full_event_vocab` stops at the 8-event set). This amendment
+re-canonicalizes #1 against the code. It is **documentation-only** — the code and
+its `test_sse_client.py` coverage already exist and pass; no code change, no
+version bump.
+
+**Corrected `Event` union** (supersedes the §Data flow Output list — 9 → 11):
+
+    WorkerPhase | Thinking | Text | TextBoundary | ToolStart | ToolResult
+    | Done | Error | Cancelled | AwaitingLlmFirstToken | AffectUpdate
+
+The two additions (both **non-terminal** — they do NOT satisfy INV-001's terminal
+requirement; the stream still ends at exactly one `Done`/`Error`/`Cancelled`):
+
+- `AwaitingLlmFirstToken(sse_id, turn_id, elapsed_ms_since_building_prompt: float)`
+  — SSE `awaiting_llm_first_token` (Worldtree #201, v0.29.0). Heartbeat during the
+  BuildingPrompt→CallingLLM gap (default 5 s); `elapsed_ms_since_building_prompt`
+  is server-authoritative monotonic. First-gap only (INV-201-5) — tool round-trips
+  do not re-fire.
+- `AffectUpdate(sse_id, status: str, turn_id, snapshot: dict | None)` — SSE
+  `affect_update` (Worldtree #204, v0.28.0). `status="current"` at turn start
+  carries the full persona snapshot; `status="scheduled"` after post-turn appraisal
+  kickoff omits it (`snapshot is None`). Suppressed for persona-disabled agents,
+  Tier-3 consumer-defined agents, and ephemeral sessions.
+
+Unknown event `type` still raises `ValueError` in `_envelope_for_type` (the
+base-contract behavior). NOTE for the eventual repin: the #371 SDK pins a
+deliberate divergence here (D-1 — skip-with-diagnostics-hook instead of raising),
+which Ratatoskr adopts only when it repins onto the SDK, not before.
+
+TESTS (already present in `tests/test_sse_client.py` — `TestAwaitingLlmFirstToken`
++ `TestAffectUpdate`; mirrored here for contract completeness):
+  single_heartbeat_parsed [tracer]: mock emits one `awaiting_llm_first_token` (turn_id, elapsed_ms_since_building_prompt=5012.3) → consumer yields AwaitingLlmFirstToken carrying both fields + parsed sse_id
+  heartbeat_sequence_monotonic [trace]: mock emits a heartbeat sequence → each yields AwaitingLlmFirstToken; elapsed_ms_since_building_prompt is monotonically non-decreasing across the sequence
+  current_status_parsed_with_snapshot [tracer]: mock emits `affect_update` status="current" with a full snapshot dict → consumer yields AffectUpdate(status="current", snapshot=<verbatim dict>)
+  scheduled_status_parsed_no_snapshot [trace]: mock emits `affect_update` status="scheduled" (no snapshot) → consumer yields AffectUpdate(status="scheduled", snapshot is None)

-  - "Tier 3 endpoints land at the same `WORLDTREE_API_URL` as the rest of the Conversation API — no separate hostname / port. Auth via the same bearer key. The caller's user_id is derived server-side from the API key's owner; the agent's `agent_id` is constructed as `<auth_user_id>:<agent_name>`. Live probe against personal Worldtree (2026-05-25) confirmed: POST with `{agent_name: 'smoke-test', ...}` and `Authorization: Bearer <key>` returned `agent_id=ratatoskr:smoke-test`, `user_id=ratatoskr`."
-  - "Per Worldtree spec §2576-2750: `agent_name` is a strict slug `[a-z][a-z0-9-]{2,63}` and immutable after definition. `user_id` is derived from the auth, must be slug-safe (`[a-z][a-z0-9-]{2,63}` per Phase 2.0 gate). PATCH accepts ONLY `system_prompt` and/or `model`; any other key (including the immutable `agent_name`, `user_id`, or layer fields `persona`/`motivational`/`valence`/`memory` — even with `null` value) returns 422 `field_not_mutable` BEFORE the DB lookup."
-  - "**Layer fields are explicitly null** on define. Phase 2.0 ships baseline addressing + ownership + lifecycle only; `persona` / `motivational` / `valence` / `memory` are schema-reserved. Non-null on these → 422 `layer_deferred`. The module's `define_agent` does NOT expose these as parameters at all — sending them would require an amendment when a future Phase enables them."
-  - "**`model` field is a provider model ID, not a profile alias.** Live probe found: `model='default'` (an llm_profiles profile name) returns 422 `model_not_available`; `model='qwen3.6-35-a3b'` (an actual provider model ID) returns 201. The CLI / module take the string verbatim and pass through — validation is server-side. Operators discover valid IDs via the model `metadata` on existing sessions or out-of-band."
-  - "**Quota: 50 Tier 3 agents per Heimdall key.** 51st define → 429 `agent_quota_exceeded` with `Retry-After: 0`. The module raises `Tier3QuotaExceeded(retry_after=0)` — the retry_after field captures the header value verbatim for forward-compat if Worldtree later returns a non-zero throttle."
-  - "**Key-revocation cascade is server-side.** When an API key is revoked (`DELETE /admin/keys/{key_id}`), every Tier 3 agent with `owner_key_hash` equal to the revoked key's hash is soft-deleted in the same SQL transaction. Active sessions on those agents return 401 `auth_revoked` on next message. The ratatoskr module doesn't track or simulate this — operators discover it via runtime 401s and the admin-side audit log."
-  - "**Picker integration is implicit** — no changes to `ratatoskr.tui.AgentPickerApp` for this issue. Tier 3 agents appear in `GET /agents` if defined and the picker's existing format `{agent_id} · {name} — {description}` renders the colon-containing agent_id without special-casing. Per issue #8 out-of-scope clause, ratatoskr does not visually distinguish Tier 1 vs Tier 3 in the picker — same UX surface."
-  - "**Session-create with colon-containing agent_id works unchanged.** Issue #5 already routes `end_user_id` into the POST /sessions body, which Tier 3 session-create requires from Phase 2.0 (per spec §2649-2664). No `ratatoskr.sessions` change needed."
-  - "**CLI uses argparse with subparsers** (define / patch / delete). The subparsers entry point lives at `python -m ratatoskr.tier3` via `__main__.py`. Output on success: prints a one-line summary (`defined ratatoskr:wizard (qwen3.6-35-a3b)` / `patched ratatoskr:wizard` / `deleted ratatoskr:wizard`). Output on error: `[<error_code>] <message>` to stderr + non-zero exit. Exit codes mirror `ratatoskr.cli`: 0 happy / 10 usage / 11 auth / 20 api-failure / 21 network."
-  - "**No `list` subcommand in v1.** A `tier3 list` operation would have to filter `GET /agents` by prefix-matching the caller's user_id, but that prefix isn't exposed in the response — only the agent_id is, and you'd have to introspect the auth's user_id. Operators discover their own Tier 3 agents by reading the `GET /agents` list (which the picker already surfaces) and looking for `<their-user-id>:*` entries. Add `list` in a follow-up if operators report friction."
-  - "**Module is standalone**: does NOT import or interact with `ratatoskr.sessions` / `ratatoskr.sse_client` / `ratatoskr.tui` / `ratatoskr.cli` beyond reusing the `USER_AGENT` constant from `ratatoskr.cli`. Cross-module use is one-way (cli supplies the user-agent string; tier3 does not import sessions). This keeps the module surface minimal and testable in isolation."
-  - "**The CLI's `python -m ratatoskr.tier3` entry point uses sys.argv handling that mirrors `ratatoskr.cli`** — a top-level `main(argv: list[str] | None = None) -> int` function that argparse-dispatches to subcommand handlers. Each subcommand handler is an async coroutine wrapped by `asyncio.run(...)`. Auth resolution: `--api-key` flag > `$WORLDTREE_API_KEY` env > `_AuthError` (exit 11). Server URL: `--server` > `$WORLDTREE_API_URL` > default `http://localhost:8000` (same default as `ratatoskr.cli`)."

Cover all success + error response codes per the ERROR_ROUTING matrix below. No live network in unit tests — the live smoke is in the acceptance criteria, not the unit tests."
-open_questions:
-  - "Should `define_agent` accept an optional `bifrost` parameter for Bifrost-bound Tier 3 sessions? The spec §2658 shows `bifrost` as a session-create field (not define-time). Draft: no — Bifrost binding is per-session; if a Tier 3 agent needs Bifrost on every session, that's an orthogonal feature on POST /sessions, not POST /agents/define. Issue #5's `--end-user-id` already covers the session-create-side parameters."
-  - "Should the CLI also offer `--end-user-id` for sessions created via tier3 + ratatoskr-cli composition? Draft: no — once an agent is defined, operators use the main `ratatoskr --new --agent <id> --end-user-id <eid>` flow; tier3 CLI is define/patch/delete only."
-  - "Should `delete_agent` support a `--force` flag for 'really delete even if active sessions exist'? Per spec §2634-2639, `DELETE` already cancels active sessions and revokes the per-resource scope grant on the owner — there's no soft fail. Draft: no — the spec's hard-delete-with-cascade behavior is the right shape; ratatoskr doesn't need to wrap it."

-# Tier 3 — Consumer-defined agent lifecycle module
-
-## Context
-
-Worldtree's Tier 3 (Phase 2.0, spec §2576-2750) lets the consumer define their own agents at `<user_id>:<agent_name>`. The agent's `user_id` is the auth's user identity (derived from the API key's owner); the `agent_name` is supplied at define-time. The lifecycle is owner-only — only the key that defined an agent can patch / delete it (modulo the key-revocation cascade).
-
-`ratatoskr.tier3` exposes this lifecycle as a Python module + small CLI tool. Picker integration is implicit (Tier 3 agents already appear in `GET /agents` per issue #8). Session-create works unchanged through `ratatoskr.sessions.create_session` since the colon-containing agent_id is opaque to that layer.

-
-## Invariants
-
-- **INV-001**: `define_agent` request body carries exactly `{agent_name, system_prompt, model}` — no layer fields, no `bifrost`, no `metadata`. Phase 2.0 baseline shape only.
-- **INV-002**: `patch_agent` request body carries ONLY `system_prompt` and/or `model` — every other key is omitted. Server-side 422 `field_not_mutable` is the safety net; client-side body-construction is the first line.
-- **INV-003**: `delete_agent` is fire-and-confirm — no body, no retry, no soft-delete. Cascade handling is server-side; ratatoskr doesn't track it.
-- **INV-004**: All exceptions carry a `[:1024]` body cap (when applicable) per the issue #2 convention.
-- **INV-005**: CLI auth resolution mirrors `ratatoskr.cli`: `--api-key` flag > `$WORLDTREE_API_KEY` > exit 11.
-- **INV-006**: CLI server URL resolution mirrors `ratatoskr.cli`: `--server` > `$WORLDTREE_API_URL` > `http://localhost:8000`.
-- **INV-007**: Module never imports `ratatoskr.sessions` / `ratatoskr.sse_client` / `ratatoskr.tui` (one-way: only `cli.USER_AGENT` is imported, and only by `__main__.py` for the outbound User-Agent header).
-- **INV-008**: All HTTP through caller-owned `httpx.AsyncClient` — module never constructs its own client. (`__main__` constructs one for the CLI entry point per ratatoskr.cli's pattern.)
-
-## TESTS (tests/test_tier3.py — new file)
-
-```
-- test_define_happy: 201 + full response shape → Tier3AgentInfo populated.
-- test_define_quota_exceeded: 429 + Retry-After header → Tier3QuotaExceeded(retry_after=N).
-- test_define_user_id_unsupported: 403 tier3_user_id_unsupported → Tier3UserIdUnsupported.
-- test_define_layer_deferred_persona: 422 layer_deferred → Tier3LayerDeferred (would only fire if the body sent a layer field; the module never sends one, so this asserts server-side defense but reflecting a 422 we don't actually generate. Test exercises the response path, not the request).
-- test_define_bad_slug: PRE-001 assertion fires before HTTP for agent_name="X" (uppercase) or "ab" (too short).
-- test_define_empty_prompt: PRE-002 assertion fires for empty system_prompt.
-- test_define_other_5xx: 503 → SessionApiFailed(status=503).
-- test_patch_happy_both_fields: 200 + updated body → Tier3AgentInfo.
-- test_patch_happy_single_field: 200 with only system_prompt set; body omits model.

-# Sessions — Worldtree Conversation API session lifecycle
-
-## Context
-
-`ratatoskr.sessions` is Ratatoskr's session-lifecycle client. Two entry points (`create_session`, `list_sessions`) plus two shared frozen dataclasses (`SessionInfo`, `SessionPage`). The module is the surface that `ratatoskr.cli` calls when `--send --new` mints a fresh session against Worldtree, and that `ratatoskr.tui` calls to populate the startup picker's `DataTable` of existing sessions.
-
-The module deliberately does NOT cover per-turn operations (those live in `ratatoskr.sse_client`), session mutation (`PATCH /sessions/{id}` is out of scope per design-brief §4 negative clauses), or session deletion (`DELETE /sessions/{id}` is admin work via `sessions_cli.py`).
-
-Convention-aligned with issue #1: caller owns the `httpx.AsyncClient` and Authorization header; the module never imports Worldtree source; responses are parsed into typed frozen dataclasses; exception `.body` payloads are truncated to `[:1024]` at construction.
-
-## Data flow
-
-**Input:**
-- `httpx.AsyncClient` (caller-owned, base_url + bearer auth on the client).
-- `agent_id: str` — for `create_session`.
-- `include_archived: bool`, `limit: int`, `cursor: str | None` — for `list_sessions`.
-
-**Output:**
-- `create_session` → `SessionInfo`:
-  - `session_id: str`
-  - `agent_id: str`
-  - `created_at: str` (ISO 8601 with offset)
-  - `last_active: str`
-  - `metadata: dict[str, Any]` (defaults to `{}` if the response omits the field — see INV-001)
-  - `message_count: int | None` (present from POST response; `None` when SessionInfo was sourced from a list item per spec §GET /sessions)
-  - `name: str | None` (always `None` when sourced from POST response; `None` if absent from list item; otherwise the list item's value)
-  - `archived: bool` (always `False` when sourced from POST response; defaults to `False` if absent or null in a list item; otherwise the list item's value)
-  - `tags: list[str]` (always `[]` when sourced from POST response; defaults to `[]` if absent or null in a list item; otherwise the list item's value)
-- `list_sessions` → `SessionPage`:
-  - `items: list[SessionInfo]`
-  - `next_cursor: str | None` (None on the last page; opaque string otherwise)
-
-**Side effects:** outbound HTTP only; no disk I/O, no global state.
-
-## Invariants
-
-- **INV-001 [hard]**: `create_session` returns a `SessionInfo` whose `session_id`, `agent_id`, `created_at`, `last_active`, and `metadata` are sourced from the 201 response body. `metadata` is taken from `body["metadata"]` when present and defaults to `{}` when absent (defensive against minor server-side spec drift; spec example always shows it present). `message_count` is taken from `body["message_count"]` (strict — bracket access, not `.get()`; the spec lists it as a response field and absent should surface as KeyError rather than silently default to None). List-only fields are fixed: `name=None`, `archived=False`, `tags=[]`.
-- **INV-002 [hard]**: `list_sessions` returns a `SessionPage` where every `SessionInfo` has `session_id`, `agent_id`, `created_at`, `last_active`, and `metadata` from the response item (same defensive `metadata` default as INV-001). `name` is `item.get("name")` (may be `None`). `archived` is `item.get("archived") or False` — absent, explicit-null, or explicit-false all yield `False`; explicit-true passes through. (Note: `item.get(key, default)` only fires `default` for absent keys, NOT for explicit-null values, so the `or False` form is load-bearing here.) `tags` is `item.get("tags") or []` (absent, explicit-null, or empty list all yield `[]`; a populated list passes through). `message_count` is `None` (the list endpoint does not include it — spec §GET /sessions: "`message_count` is not included in list items").
-- **INV-003 [hard]**: `list_sessions` treats cursors as opaque strings. The module never parses, base64-decodes, or constructs a cursor — it threads the server-provided `next_cursor` back verbatim on the next call. Per spec §Pagination ("Cursors are opaque to clients — do not parse or construct them.").
-- **INV-004 [hard]**: Both functions truncate exception `.body` payloads to `[:1024]` at construction. Matches the issue #1 precedent (`SseConnectFailed`, `CancelFailed`).
-- **INV-005 [hard]**: No `core.*` or `worldtree.*` imports. Boundary verified by `tests/test_no_worldtree_imports.py`.
-- **INV-006 [hard]**: `list_sessions` rejects out-of-range `limit` values (`< 1` or `> 200`) client-side before issuing any HTTP request. Spec §GET /sessions specifies the server returns 422 on out-of-range; the client refuses to send an obviously-invalid request rather than depending on the server to reject it.
-
-## Constraints
-
-- **[compatibility]** Module must work against the spec pin (`55101e909abcd2219833266b6f905c5bc956e0f0`, Worldtree v0.19.0).
-- **[security]** Module does not log full response bodies (they may carry user-readable session names + tags). Logging limited to status code + session_id when present.
-- **[style]** Async-native. No sync entry points. Consistent with `sse_client`.
-
-## Out of scope
-
-- **Bifrost binding** (Worldtree issue #160). `create_session` does not accept or send a `bifrost` field. Ratatoskr is not a Bifrost consumer; consumer-side tool injection is an advanced feature outside the dev TUI's purpose.
-- **Ephemeral / Saga sessions.** Separate session class with TTL semantics; not needed for hands-on dev probing.
-- **`GET /sessions/{id}` (single fetch), `PATCH /sessions/{id}` (mutation), `DELETE /sessions/{id}` (deletion).** Per design-brief §4 negative clauses; admin operations live outside Ratatoskr.
-- **`GET /sessions/{id}/messages` (history pagination).** Deferred until the TUI needs scrollback replay; `--send` doesn't need history.
-- **Transparent multi-page iteration.** `list_sessions` returns one page; caller threads `next_cursor` for the next call. Don't add an `iter_all_sessions()` until the TUI proves it needs that shape.
-- **Server retry / backoff.** Caller's policy. The module does not retry on 5xx; it surfaces failure once and returns control.

-## 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.

-FN get_session_messages(client: httpx.AsyncClient, session_id: str) -> dict[str, Any]
-BRIEF: GET /sessions/{session_id}/messages — the session's message history (spec §GET /sessions/{id}/messages), un-deferred as the #347 probe's read-back so a seeded turn can be confirmed to render as a normal role=assistant message (model-invisible provenance — a seed is indistinguishable from a lived turn on read). Returns {session_id, items:[{seq, role, content, ...}], next_cursor} verbatim. Owner-scoped; any non-200 → SessionApiFailed. v1 reads the server default page (no pagination params — the probe reads a fresh 1-message session; add limit/cursor when a caller needs scrollback).
-PRE: [PRE-001 hard] client is not None -- assert client is not None
-PRE: [PRE-002 hard] session_id is a non-empty str -- assert session_id and isinstance(session_id, str)
-POST: [POST-001 return_value] on 200 returns resp.json() unmodified
-ERROR_ROUTING:

+
+# worldtree-sdk cutover — consumer-layer adapter contract
+
+Single SDK-adapter contract per operator DEC-1. This is a migration contract: its
+spine is a route-family slice plan, not a dense FN-block spec — each slice's
+adapter FN detail is filled in at that slice's TDD (incremental migration; the
+per-route SDK signatures are already mapped below).
+
+## Locked design (operator-accepted 2026-07-18, post vor-cross)
+
+- **DEC-1 — retire, don't repurpose (two-phase).** Normative authority for the
+  consumer wire transfers to THIS contract immediately (as of this file, #2 sessions
+  and #15 tier3 are superseded — no longer the spec of record); the contract FILES
+  are DELETED at slice-7 teardown, only after the code they specified is gone
+  (avoids both orphaning live code and leaving obsolete norms active mid-migration).
+  `first_message` is NOT retired — it stays a ratatoskr-owned usage contract at the
+  spec level (its preset / best-effort-timeout / swallow policy is local, not
+  SDK-owned). Repurposing the wire contracts would risk a shadow-normative copy of
+  SDK-owned semantics — the exact thing the cutover eliminates.
+- **DEC-2 — thin semantic error adapter.** CLI/web/TUI keep ratatoskr's typed
+  exceptions; the adapter maps the SDK's `ApiError` floor → ratatoskr's
+  caller-semantic types (the SDK stays undiscriminated; hide-existence maps here).
+- **DEC-3 — no shims (house rule).** Delete the old wrapper modules and update all
+  call-sites to the new adapter. No compatibility facade preserving old
+  module/function APIs (pre-1.0 no-backwards-compat rule).
+- **DEC-4 — incremental + live-smoke, no soak.** Migrate one route-family per
+  slice, TDD each slice, and run a targeted LIVE smoke of that family against the
+  personal endpoint before deleting the replaced hand-rolled path. (The SDK's
+  fixture corpus proves the WIRE; the live smoke proves ratatoskr's
+  presenter/adapter/env-wiring survived the dependency inversion.)
+  **Smoke acceptance bar (the minimum that lets an old path be deleted):** drive
+  each route in the family's primary flow END-TO-END through the ratatoskr surface
+  (CLI/web) — not the wrapper directly — against the personal endpoint under the
+  real consumer key, and OBSERVE the expected success (a created session, a streamed
+  turn that renders, a persona write that reads back), not merely a non-crash. A
+  smoke that only asserts "no exception" does NOT clear the bar. **Smoke vs. soak
+  boundary:** a smoke is a single pass of the family's flows at deletion time; a
+  (forbidden) soak is a sustained dual-path parallel-run — do the former, not the
+  latter.
+- **DEC-5 — wait for the registry.** Pin `worldtree-sdk == 1.0.0` from the internal
+  Gitea registry once published (verify the uv install first); use the
+  `python-v1.0.0` git tag only if the registry lags. Contract-drafting is NOT
+  gated (SDK source is inspectable); IMPLEMENTATION pin is.
+- **DEC-6 — minor bump at ship.** The cutover ships as a minor (architecture-cutover
+  milestone; pre-1.0 breaking-internal) — requires explicit operator approval at
+  ship time, not now.
+
+## Adapter design
+
+- **`ratatoskr.wt`** — a thin adapter module owning ONE `WorldtreeClient`, built
+  with ratatoskr's own `httpx.AsyncClient` injected (`transport=`), ratatoskr's
+  `auth`/`admin_auth` providers, and the ratatoskr User-Agent. It exposes
+  ratatoskr-semantic call surfaces the presenters already expect, and translates
+  SDK errors → ratatoskr exceptions (DEC-2).
+- **Transport ownership (INV-CUT-1 [hard]):** the injected `AsyncClient` is
+  ratatoskr-owned; `WorldtreeClient.aclose()` / `async with` exit must NOT close
+  it (SDK `_owns_client=False` on injection). Ratatoskr owns the client lifecycle
+  exactly as today.
+- **Error boundary (INV-CUT-2 [hard]):** ratatoskr's caller-semantic exceptions
+  are raised by the adapter, mapping from the SDK where the SDK already
+  discriminates (`AgentNotAvailable`, `TurnLaunchUnavailable`, `SessionRetired`,
+  `Cancel*`, `Resume*`, `Malformed*`) and from `ApiError(status=..., error_code)`
+  on a KNOWN route otherwise — including the hide-existence 404 →
+  `AuthoredHistoryUnavailable` (labeling a call we made, NOT capability-probing).
+- **Provider boundary (INV-CUT-3 [hard]):** the Bifrost provider planes stay
+  hand-rolled and are never routed through the SDK. The Bifrost-BOUND
+  `sessions.create` (consumer-side, `bifrost=` + consumer-key auth) DOES go through
+  the SDK and stays consumer-layer.
+- **Import boundary (INV-CUT-4 [hard]):** `tests/test_no_worldtree_imports.py`
+  stays; the boundary becomes "no Worldtree SOURCE imports", with `worldtree_sdk`
+  the allowed client dependency.
+
+## Invariants
+
+- **INV-CUT-1 [hard]** — Ratatoskr owns the injected `httpx.AsyncClient` lifecycle;
+  the SDK never closes it (`_owns_client=False` on transport injection).
+- **INV-CUT-2 [hard]** — The adapter raises ratatoskr's caller-semantic exceptions
+  per the explicit **§ Error map** table below — mapping from the SDK's discriminated
+  errors (passthrough) and from `ApiError` by the ROUTE that raised it (the route is
+  the discriminator, never the body). Every `ApiError` is mapped; the default is
+  `SessionApiFailed`. No route invents semantics the table doesn't list.
+- **INV-CUT-3 [hard]** — The Bifrost PROVIDER planes never route through the SDK;
+  the Bifrost-BOUND `sessions.create` does (consumer-side).
+- **INV-CUT-4 [hard]** — The no-Worldtree-SOURCE-import boundary holds
+  (`worldtree_sdk` allowed); `tests/test_no_worldtree_imports.py` enforces it.
+- **INV-CUT-5 [hard]** — Each slice runs a LIVE smoke of its route family before the
+  replaced hand-rolled path is deleted (DEC-4); no old path is removed unproven.
+
+## Route map — ratatoskr wrapper → SDK method (grounded @ python-v1.0.0)
+
+| Ratatoskr wrapper (retiring) | SDK method | SDK return |
+|---|---|---|
+| `create_session` | `sessions.create(...)` | `SessionInfo` |
+| `list_sessions` | `sessions.list(limit, cursor)` | page |
+| `stream_turn` | `sessions.stream_turn(...)` (resilient) / `stream_turn_raw` (single) | `AsyncIterator[Event]` |
+| `reconnect_turn` | folded into `sessions.stream_turn` auto-resume | — |
+| `cancel_turn` | `sessions.cancel_turn(...)` | `CancelResult` |
+| `get_session_messages` | `sessions.messages(id)` | open-world |
+| `get_session_tools` | `sessions.tools(id)` | `SessionTools` |
+| `set_persona_state` | `sessions.set_persona_state(id, PadState)` | None |
+| `write_authored_history` | `sessions.write_history(...)` | authored-turn |
+| `get_persona_state` | `agents.persona_state(agent_id)` | `AgentPersonaState` |
+| `list_agents` | `agents.list()` | `AgentList` |
+| `define_agent` | `agents.define(...)` | `DefinedAgent` |
+| `patch_agent` | `agents.patch(id, changes)` | `PatchedAgent` |
+| `delete_agent` | `agents.delete(id)` | None |
+| `get_me` | `me.get()` | `MeInfo` |
+| `get_capabilities` | `capabilities.get()` | `Capabilities` |
+| `list_character_models` | `models.available_for_characters()` | `ModelsAvailable` |
+| `create_character` | `characters.create(...)` | `CreatedCharacter` |
+| `get_character_state` | `characters.state(id)` | `CharacterState` |
+| `delete_character` | `characters.delete(id)` | `CharacterDeleteResult` |
+| `get_session_bifrost` | `admin.sessions.bifrost(id)` | `BifrostInspection` |
+| `stream_admin_events` | `admin.stream_events(...)` | `AsyncIterator[AdminEvent]` |
+
+Note: SDK returns are typed `shapes.*`; per the parity pass the freeform reads
+(`SessionTools`, `BifrostInspection`, capabilities) are deliberately open-world in
+the Python spine. The adapter PASSES THESE THROUGH unmodified (does not normalize);
+presenters read them as mappings, tolerant of wire drift. If an open-world read is
+malformed the presenter degrades (never crashes) — same posture as the existing
+`_format_whoami` hardening.
+
+## Error map (INV-CUT-2 — the explicit table)
+
+**The ROUTE is the discriminator, not the error body** (labeling a call we made, NOT
+capability-probing — B-ERR-4). A 404 is mapped by which method raised it; the adapter
+NEVER sniffs the body to decide whether something exists. Authored-history is
+currently the ONLY hide-existence route (per Worldtree B-ERR-4); if Worldtree adds
+others, they get their own row here — the default is NOT a general "any 404 → hidden".
+
+| SDK raises (from) | Adapter maps to |
+|---|---|
+| SDK `AgentNotAvailable` / `TurnLaunchUnavailable` / `SessionRetired` (stream-open) | ratatoskr `AgentNotAvailable` / `TurnLaunchUnavailable` / (retired → `SessionApiFailed`) — same names, passthrough |
+| SDK `ConnectionDropped` (mid-stream) | `SseConnectionDropped` |
+| SDK `ResumeError` subclasses (in resilient stream) | resilient `stream_turn` absorbs; terminal → `SseConnectFailed` |
+| SDK `MalformedSseId` / `MalformedSseData` / `TurnIdFlip` (stream `ProtocolError`) | ratatoskr same-named types — same-name rewrap of the discriminated stream protocol errors |
+| SDK `Cancel*` (cancel_turn) — the SDK RAISES the typed races | 404 `turn_not_found` → `CancelTurnNotFound`; 409 `turn_finished` → `CancelAlreadyCompleted`; other `CancelError` → `CancelFailed`. A 200 (incl. `cancelled=False`, the B-CAN-3 late-cancel no-op) returns a `CancelResult` — never raises. The caller surface stays exception-based (DEC-2; matches the pre-cutover CLI/web handlers). |
+| `ApiError(404)` on `sessions.create` | `AgentNotFound` |
+| `ApiError(404)` on `sessions.write_history` | `AuthoredHistoryUnavailable` (hide-existence) |
+| `ApiError(422 cursor_invalid)` on `sessions.list` | `InvalidCursor` (dual-key: status 422 AND error_code; the flat cursor body surfaces the code) |
+| `ApiError(502)` on bound `sessions.create` | `BifrostHandshakeFailed` — NOT gated on error_code (unlike list's 422): INV-002, the synchronous handshake is the SOLE bound-502 cause; and the SDK's envelope parser prefers the nested `detail` (which carries `bifrost_error`, not `error_code`), so no distinguishing top-level `error_code` surfaces. The route+status IS the discriminator. |
+| `ApiError(429)` on `agents.define` (slice-4) | `Tier3QuotaExceeded(retry_after=0)` — the SDK's `ApiError` floor carries no response headers, so the `Retry-After` header the hand-rolled path read is unavailable; spec §2675 pins Phase-2.0 quota to `Retry-After: 0`, so the adapter defaults to 0. A non-zero forward-compat value is unrecoverable until the SDK surfaces headers (INFORM wtsdk-dev; reference-impl posture). |
+| `ApiError(403 tier3_user_id_unsupported)` on `agents.define` (slice-4) | `Tier3UserIdUnsupported` (dual-key: status 403 AND error_code) |
+| `ApiError(422 layer_deferred)` on `agents.define` (slice-4) | `Tier3LayerDeferred(field)` — `field` parsed from the body (`detail.field` / flat `field`); the SDK carries `error_code` but not `field`, so the adapter body-parses it (same posture as bound-502's `bifrost_error`) |
+| `ApiError(404)` on `agents.patch` / `agents.delete` (slice-4) | `Tier3AgentNotFound` (route-discriminated; agents CRUD is NOT a hide-existence route — a 404 there IS "no such agent") |
+| `ApiError(422 field_not_mutable)` on `agents.patch` (slice-4) | `Tier3FieldNotMutable(field)` (dual-key status+error_code; `field` body-parsed) |
+| `ApiError(404 persona_not_configured)` on `agents.persona_state` (slice-4) | `PersonaNotConfigured` (dual-key) |
+| `ApiError(404 agent_not_available)` on `agents.persona_state` (slice-4) | `AgentNotAvailable` (the persona-surface `sessions.AgentNotAvailable`, distinct from the eager-turn `sse_client.AgentNotAvailable`; dual-key) |
+| `ApiError(403 auth_scope_denied)` on `agents.persona_state` (slice-4) | `AuthScopeDenied(scope="persona.read")` (dual-key) |
+| **`ApiError` (any other status/route, incl. `agents.list` and any unmatched agent-route code) — the default** | `SessionApiFailed(status, error_code, body)` |
+
+The default row is load-bearing: any `ApiError` not matched above surfaces as the
+generic `SessionApiFailed` carrying the raw `status`/`error_code`/`body` — the
+adapter does NOT invent per-route semantics the contract doesn't list, and does NOT
+leave an `ApiError` un-mapped. **This default holds on EVERY route, including the
+stream and cancel** (each carries a defensive `except ApiError → SessionApiFailed`
+after its discriminated branches — the SDK maps those routes to discriminated types
+today, but the default guarantees INV-CUT-2 structurally, not by SDK-internal
+coupling). Each slice adds/confirms its route's rows here before the old path is
+deleted.
+
+## Slice plan (incremental, DEC-4)
+
+Each slice: wire the family through `ratatoskr.wt` → update call-sites → TDD →
+LIVE smoke against the personal endpoint → delete the replaced hand-rolled path →
+re-anchor its coverage-map rows.
+
+1. **Foundation** — `ratatoskr.wt` module + injected `WorldtreeClient` + auth
+   providers + the error-adapter skeleton (the § Error map's default `ApiError` →
+   `SessionApiFailed` rule + the discriminated-error passthrough). No USER-VISIBLE
+   behavior change (imports/construction change; the skeleton is unit-tested but
+   unexercised by any surface until slice 2). Done = `ratatoskr.wt` importable, the
+   client constructs with an injected transport, and the error-map default is unit-
+   covered.
+2. **Sessions/turn** — create/list/messages/tools/cancel + the turn STREAM + the
+   Bifrost-bound create. The turn presenter wires the resilient `sessions.stream_turn`
+   (auto-resume — this ABSORBS the old `reconnect_turn`, which is deleted this slice
+   with its call-sites); `stream_turn_raw` is available for a single-attempt caller
+   but is NOT the presenter default. (Highest-traffic; the SSE presenter is the
+   riskiest wiring.)
+3. **Persona + authored-history** — set_persona_state (PadState) + write_history
+   (hide-existence mapping) + first_message presets (stay ratatoskr-owned OVER the
+   SDK method).
+4. **Agents (Tier-3)** — list/get/define/patch/delete/persona_state. (Folds in the
+   pending `model`→`role` cutover — see [[project-tier3-agents-model-to-role-pending]].)
+5. **Characters + me/capabilities/models** — the remaining consumer reads.
+6. **Admin** — admin.sessions.bifrost + admin.stream_events (admin_auth).
+7. **Teardown** — delete residual hand-rolled modules; drop `httpx-sse` (SDK owns
+   SSE parsing); retire contracts #2/#15; final coverage-map re-anchor; minor bump
+   (DEC-6, operator approval).
+
+### Slice-4 notes (Agents/Tier-3 + `model`→`role` fold, decided at TDD)
+
+- **`model`→`role` cutover folds in here (scope B).** Worldtree spec 1.2 (`v1.0.0b128`,
+  live on :8080/:8081) made the `/agents/define` response echo `role`, closing the
+  old W-4 `model` echo. The adapter returns the SDK's OPEN-WORLD `DefinedAgent` /
+  `PatchedAgent` dicts verbatim (parity posture); callers read `info["role"]`. The
+  frozen `Tier3AgentInfo` dataclass (which read `body["model"]` and would KeyError
+  post-b128) is DELETED — no dataclass normalization layer survives.
+- **`ratatoskr.local_agents` schema bump.** `LocalAgentEntry.model` → `.role` (the
+  field stores what the wire now calls a role); `_SCHEMA_VERSION` 1→2 so any
+  pre-cutover on-disk index is discarded cleanly (no-backwards-compat, DEC-3).
+- **`AgentNotAvailable` name collision.** `sessions.AgentNotAvailable` (persona-state
+  404 `agent_not_available`) and `sse_client.AgentNotAvailable` (eager-turn 409) are
+  distinct types that share a name; `wt` already imports the sse_client one for the
+  stream, so it imports the persona one ALIASED (`PersonaAgentNotAvailable`) and
+  raises it from `get_persona_state`. The web endpoint keeps importing the persona
+  `AgentNotAvailable` from `sessions` (same class), so its `except` is unchanged.
+- **`ConnectFailed` at every rewired caller (slice-3 foot-gun).** The SDK normalizes
+  ANY transport failure to `ConnectFailed(status=0)` (`request.py`), not a raw httpx
+  error. The rewired tier3 CLI and both web endpoints (`_agents_endpoint`,
+  `_persona_state_endpoint`) catch `wtsdk.ConnectFailed` → their existing
+  network-error surface (CLI exit 21 / web 502). The web `test_network_error_returns_502`
+  (respx `httpx.ConnectError` side-effect) is the RED that proves this.
+- **`agents.get(agent_id)`** (SDK `GET /agents/{id}`) is NOT wrapped — ratatoskr has no
+  `get_agent` consumer; only list/persona_state/define/patch/delete are in coverage.
+- **Client-side Tier-3-id PRE on `patch_agent` / `delete_agent`.** Both assert
+  `":" in agent_id` pre-HTTP (a Tier-3 id is always `<user_id>:<agent_name>`, ADR-0019),
+  so a non-colon id fails fast with an `AssertionError` rather than reaching the SDK's
+  route-discriminated 404 → `Tier3AgentNotFound`. Intentional fail-fast on a
+  wrong-shaped id (carried over from the retired hand-rolled wrappers); documented here
+  per the heid-code-review slice-4 precision flag (the § Error map 404 rows assume a
+  well-formed Tier-3 id reaches the route).
+
+### Slice-5 notes (Characters + me/capabilities/models, decided at TDD)
+
+- **No new § Error map rows.** All six routes (`me.get`, `capabilities.get`,
+  `models.available_for_characters`, `characters.create` / `.state` / `.delete`) are
+  open-world reads/acks (B-OPEN-2) whose SDK ops carry NO discriminated error (no
+  `map_error`), so every `ApiError` maps to the default `SessionApiFailed` — exact
+  parity with the retiring hand-rolled path, which likewise raised only its generic
+  `SessionApiFailed` on any non-2xx (never discriminating a status/code on these
+  routes). The route-map table above already lists all six.
+- **`create_character` body — omit `state` when None.** The adapter sends
+  `{"character": …}` plus `"state"` only when the caller supplies a non-None state
+  (the SDK forwards the body dict as-is via httpx `json=`). This drops the hand-rolled
+  path's redundant explicit `"state": null` — server-equivalent (Worldtree's
+  `CreateCharacterRequest.state` defaults None whether omitted or explicit-null),
+  SDK-idiomatic (matches the SDK's `CreateCharacterInput` `NotRequired` shape), and
+  invisible at the sole call-site (`--characters` never passes a state). Adopt-
+  canonical over byte-for-byte wire parity.
+- **`delete_character` returns the SDK's open ack verbatim (`-> Mapping | None`).**
+  The SDK route returns an open-world ack body (not 204 — `CharacterDeleteResult`), so
+  the adapter passes it through rather than normalizing to the hand-rolled `None`
+  (parity posture: no None-normalization of an open-world read). On a 204 no-content
+  the SDK yields `None`, so the return type is `Mapping | None`; the sole call-site
+  (`--characters`) ignores the value, so the change is unobservable.
+- **Open-world presenter degrade-not-crash (cumulative foot-gun).** `_format_whoami`
+  is already hardened (slice-4 heid bug-hunt). The rewired `_characters_probe` extracts
+  the created id defensively (`created.get("character_id")` + type-guard → clean abort,
+  never a hard-index KeyError) since the create ACK is now an open-world SDK read.
+- **Container-type hardening (heid code-review + bug-hunt slice-5).** The degrade-not-
+  crash floor is guarded at THREE levels for the CLI presenters, not just one: (a) the
+  list-typed fields `scopes` / `allowed_roles` / model `items` degrade a non-list scalar
+  (`123`) or a bare string to empty via `_display_seq` / an `isinstance(_, list)` guard —
+  the older `or []` idiom only caught null/absent and would `for x in 123` `TypeError`;
+  (b) each element is type-guarded (`isinstance(m, dict)`); (c) the top-level open-world
+  reads `created` / `models` / `state` are `isinstance(_, Mapping)`-guarded before any
+  `.get` (a non-mapping passthrough would otherwise `AttributeError`). All three feed
+  `--whoami` / `--characters` only.
+- **Accepted (not fixed): the `--characters` probe leaks its transient character on a
+  mid-lifecycle failure.** create → get-state → delete runs linearly with no `finally`,
+  so a state/delete failure after a successful create orphans the probe character until
+  its TTL. This is PRE-EXISTING (the retired hand-rolled probe had the identical
+  structure — the cutover did not worsen it), TTL-bounded, and `--characters` is a
+  one-shot diagnostic smoke; a `try/finally` cleanup would also swallow a happy-path
+  delete-failure (delete is both the teardown AND a tested lifecycle step). Accepted as
+  known-risk per the heid bug-hunt (Gróa + Heid concur accept is defensible).
+- **CLI-only rewire.** `me` / `capabilities` / `characters` / `models` have NO
+  web-server caller — only the `--whoami` and `--characters` CLI one-shot probes. The
+  web surface is untouched this slice.
+
+### Slice-6 notes (Admin: bifrost inspection + admin-events stream, decided at TDD)
+
+- **Admin auth moves from a per-call header override to the client's `admin_auth`.**
+  The SDK's `admin.*` methods authenticate with the client's `admin_auth` provider
+  (set via `build_client(admin_key=...)`), NOT a per-request `Authorization` header. So
+  the two web admin endpoints build their wt client WITH `admin_key` (`_wt_client(client,
+  admin_key=...)`, extended this slice); the hand-rolled per-call `admin_key=` +
+  header-override is retired. The web already guards `if not admin_key: 400` before the
+  call, so the SDK's pre-HTTP `ConfigurationError` (missing admin_auth, W-5) is
+  unreachable from the web surface. **CLI has no admin caller** — both routes are
+  web-only (the coverage-map's `tui.py` rows were stale; corrected to `web/server.py`).
+- **`get_session_bifrost` — no new § Error map row.** `client.admin.sessions.bifrost`
+  returns the open-world `BifrostInspection` dict verbatim; any `ApiError` (notably 403
+  `auth_scope_denied`, 404 `session_not_bifrost_bound`) → the `SessionApiFailed` default
+  — exact parity with the retired path (which mapped every non-200 → `SessionApiFailed`).
+- **`stream_admin_events` re-wraps the SDK's `AdminEvent` → ratatoskr's `AdminEvent`
+  (chosen over yield-through).** The SDK's `AdminEvent` diverges from ratatoskr's:
+  `admin_id: int|float` (`nan` for an id-less envelope) vs ratatoskr's `id: int` (0
+  default), and the SDK's `type`/`data` are None-able where ratatoskr's are a dotted-str
+  / a `{}`-default dict. The web filter + SSE formatter read `ev.id`/`ev.type`/`ev.data`.
+  The adapter re-wraps at the boundary — `id = admin_id if int else 0` (nan→0),
+  `type = type or ""` (None→"" so `.startswith` never crashes), `data = data or {}` —
+  degrading the SDK's open-world None/nan ONCE at the adapter, keeping the web endpoint +
+  `_admin_event_matches_web` + the ratatoskr `AdminEvent` domain type UNCHANGED (preserves
+  the web surface per § Out of scope). **Rejected alternative:** yield SDK `AdminEvent`s
+  through and rewire the web filter for `admin_id`/None/nan (the slice-2 turn-stream
+  precedent) — heavier web churn + scatters the None/nan hardening through the filter;
+  re-wrap localizes it. The ratatoskr `AdminEvent` dataclass stays in `sse_client.py` this
+  slice (imported by `wt` + the web); its home moves in slice-7 teardown if `sse_client.py`
+  is retired.
+- **Admin-stream error mapping (reuses the § Error map stream rows).** The SDK admin
+  stream raises `ApiError("admin_stream_failed", status=…)` on a NON-200 open (NOT
+  `ConnectFailed` — a gotcha the web integration test caught that the unit fake could not)
+  → `SseConnectFailed`; and `ConnectionDropped` on a connect-time transport failure
+  (cursor None) OR a mid-stream drop / the long-lived stream's resumable EOF (cursor set)
+  → `SseConnectionDropped`. The SDK admin stream is best-effort (skips malformed frames —
+  no `Malformed*`), as was the retired hand-rolled path; the web endpoint's existing
+  `except (…, MalformedSseId, MalformedSseData)` stays a harmless defensive superset
+  (pre-existing, not introduced here).
+
+### Slice-7 notes (Teardown — the LAST slice, decided at teardown)
+
+- **Module boundary: KEEP `sessions.py` + `sse_client.py` as pure type/exception
+  homes (operator decision A1, 2026-07-19).** Post-cutover both modules hold NO
+  client — only ratatoskr's caller-semantic exception surface + a couple of
+  dataclasses (`BifrostBinding`; `SseId`, `AdminEvent`) + the `endpoint_for_plane`
+  provider helper. Options weighed: (A1) keep as-is + fix docstrings; (A2) rename to
+  honest names (`session_errors`/`stream_errors`), re-point ~7 importers; (A3)
+  consolidate into one `errors.py` / fold into `wt.py`. **A1 chosen** — teardown is
+  deletion + dep-drop, not a rename refactor; A3 is blocked by the `AgentNotAvailable`
+  name collision (two distinct classes: persona-404 in `sessions` vs eager-turn-409 in
+  `sse_client`) which would force renaming a contract-level caller-semantic type + its
+  § Error-map rows + catch sites, and folding into `wt.py` mis-homes
+  `endpoint_for_plane` (provider-side). Naming-honesty (principle-2) addressed by the
+  one-line docstring note, not a rename. **Resolves the slice-6 open item** (line ~326):
+  the ratatoskr `AdminEvent`/`SseId` + exceptions stay in `sse_client.py`; the
+  session/tier3 exceptions + `BifrostBinding` stay in `sessions.py`.
+- **`httpx-sse` dropped from `pyproject.toml` + lockfile.** Slice-6 deleted its last
+  user (`sse_client.stream_admin_events`); a tree grep confirmed nothing imports
+  `httpx_sse`. `uv sync` physically pruned it; suite green (494) with the module absent.
+- **Wire contracts #2 (sessions) + #15 (tier3) retired (files DELETED, DEC-1
+  phase-2).** Their normative authority transferred to this contract at authoring;
+  the code they specified is gone, so the files are removed now. **#1 (SSE event
+  vocabulary) is NOT retired** — it stays current (amended `4bd9abd` 2026-07-18) as
+  ratatoskr's SSE-event-rendering reference; **`first_message` is NOT retired** (DEC-1,
+  ratatoskr-owned usage contract). Accepted side-effect: `issues/5.contract.md`'s
+  historical "amended #2/#3/#4 in-place" line now points at a deleted #2 — left as-is
+  (frozen issue-record of a past action; not expanding DEC-1's #2/#15 scope).
+- **Final coverage-map re-anchor.** `GET /sessions/{id}/tools` → `wt.py get_session_tools`
+  (SDK `sessions.tools`) → `web/server.py` (the old `sessions.py`→`tui.py` row was
+  stale; TUI deleted). `GET /sessions` `list_sessions` re-homed to `wt.py`, still
+  caller-less (picker was a TUI frontier, now moot). The `Last-Event-ID` SSE-resume
+  sub-gap is CLOSED — `reconnect_turn` deleted, resume folded into `wt.py stream_turn`
+  auto-resume. Surface-2 SSE parsing re-anchored to the SDK (`_envelope_for_type` gone).
+- **Ships as v0.22.0 (minor, DEC-6, operator-approved 2026-07-19).** Publishes the
+  full 6-slice consumer-layer cutover milestone.
+
+## Out of scope
+
+- Bifrost PROVIDER planes (memory/affect) — hand-rolled, ADR-0009, untouched.
+- CLI / TUI / Starlette web surfaces — their EXTERNAL BEHAVIOR is preserved (their
+  call-sites DO change — they're updated to the new adapter per `touches:`; what's
+  invariant is the observable behavior, not the code).
+- The four parked post-v1 SDK ergonomics items (replayed:bool, raw-dict persona
+  escape hatch, list_all iterator, split session types) — coordinated post-v1 lane
+  with wtsdk-dev, not this cutover.
+
+## Coverage-map re-anchor
+
+`docs/coverage-map.md` shifts from "hand-rolled route exists + live-proven" to
+"SDK method wired and exercised by a ratatoskr surface"; excluded-by-design rows
+stay explicit. Re-anchored per slice as each family lands.

+"""Descriptive-query subject-binding probe — the canonical fixture for Worldtree #393.
+
+#393: an ATTRIBUTE/descriptive question ("the guy with the roid rage") reformulates to a
+token query that matches MULTIPLE distinct canon subjects on a shared word ("rage"), so the
+intended entity can be absent from top-k while topically-adjacent decoys rank above it. The
+name-check (`names_subject`) can't help — the caller has no name to pass until the attribute
+is resolved to an entity, which is the open problem. Downstream, the consumer sometimes binds
+to the wrong co-retrieved subject and cross-contaminates details (a confident, fluent mis-bind
+assembled from real-but-mismatched rows, not a hallucination).
+
+Two regimes at DIFFERENT WING SCOPES (the distinction is load-bearing — Worldtree #393):
+  * RAW RANKING — ALL-WING (mimir searches kb+main+fiction, ~9800 rows). Drive `mimir` with the
+    descriptive query + variants; report the query mimir ACTUALLY passed (tool_start q=, since it
+    reformulates) and where the intended ENTITY lands. Cross-wing dilution can push a one-arm
+    vector bridge out of the bge rescue window entirely -> entity ABSENT from top-k.
+  * CONSUMER — FICTION (ratatoskr:donut is fiction-scoped, ~1578 rows). Drive Donut N times;
+    classify BINDS-ENTITY vs MIS-BINDS-DECOY vs OTHER, and report where the ENTITY and DECOY rank
+    in her fiction-scoped results. The ranks tell WHICH failure fired per run: entity PRESENT +
+    mis-bind = subject-selection; entity ABSENT + a present decoy = reformulation-induced absence
+    (Donut distilled the descriptive phrase to bare tokens that don't carry the vocabulary bridge).
+    Empirically Donut mostly does the latter — she distills "the guy with the roid rage" to bare
+    "roid rage", so Juicer drops out even at fiction scope and she binds a present decoy (Jack).
+
+Two-seam finding (2026-08-07, v1.0.0b181) — both lose the entity, by DIFFERENT reformulation seams:
+(1) mimir PRESERVES the phrase -> cross-wing dilution (kb+main+fiction) drops the entity from its
+all-wing top-k; (2) Donut DISTILLS the phrase to bare tokens -> the entity drops even at fiction
+scope (ent@None) and she binds a present decoy. The fold's ENT@/DEC@ ranks separate reformulation-
+absence from true subject-selection per run. Unifying lever: disambiguating-vocabulary expansion
+(the full phrase, or +attribute like "steroid") surfaces the entity at fiction scope — Donut's
+expand-runs bind correctly. "dangerous crown" is mostly RESOLVED (one entity). Root gap:
+attribute->entity resolution, upstream of names_subject by construction.

+"""Fiction-wing retrieval probe harness — the recipe R42 (brokkr-smithy-dev) builds against
+and the re-runnable #389 acceptance gate.
+
+Two retrieval paths, kept SEPARATE because they have different noise properties:
+
+  * search_library (raw, RANKING-clean): drive the `mimir` foundational agent (all-wing
+    librarian) with a FIXED query string. Deterministic against a fixed index — use it for
+    ranking baselines (R42 arm-2). No LLM in the query loop.
+  * reference_knowledge (the Tier-3 consumer path): drive `ratatoskr:donut`; her reasoning
+    REFORMULATES the query each turn, so this path carries QUERY-FORMULATION variance
+    (the arm-4 signal), attributable via the captured tool_start query. NOT for ranking numbers.
+
+Scoring conventions (identical across both paths and all R42 arms):
+  * confidence BUCKET vs WT's RRF thresholds: high >= 0.030, medium >= 0.016, low < 0.016.
+  * ON-TARGET (load-bearing): a returned row is on-target iff its excerpt actually NAMES or
+    describes the queried subject (keyword match on the subject's distinctive tokens). The
+    failure signature "10 hits / MEDIUM / 0 on-target" = present-by-topic, subject absent —
+    the split that separated #384 (packaging) / #387 (coverage) / #389 (ranking).
+  * MISS = no on-target row in the returned top-k.
+
+Noise floor: freeze the generation (pin the b-tag) to remove extraction variance; fixed-string
+search_library is deterministic (no CI needed); reference_knowledge variance is query-
+formulation, not floor noise. Residual = bucket-boundary sensitivity at 0.016/0.030 — so probe
+N>=3-5 times per term and report the bucket DISTRIBUTION, never a single-run point label.
+
+Session protocol: ONE fresh session per query. A reused mimir session returns EMPTY
+search_library results after its first turn (Worldtree #391), silently scoring later terms
+false-MISS; the retrieval helpers self-session to enforce it. Never hoist the session out.
+

+after X", "earliest to latest") need CHRONOLOGICAL order, but reference_knowledge sorts by
+RELEVANCE by default. The fix is an `order_by="chapter"` tool flag (enum ["chapter"], taught
+in both tool schemas; the result packet carries `ordered_by="chapter"` and hits are reordered
+by source chapter, earliest first). Confirmed live on personal b184.
+
+This measures the flag END-TO-END (before/after per the #393 discipline) on three axes:
+  - ADOPTION: for a temporal query, does the agent actually invoke order_by="chapter"? (the
+    schema teaches it, but usage varies turn-to-turn — the #397 analog of query-formulation
+    variance).
+  - MECHANISM (flag applied): are the served hits' provenance.chapter monotonically
+    non-decreasing (earliest first)? Should be ~100% when the flag fires.
+  - VALUE (flag not applied): the relevance baseline — chapters are NOT chapter-sorted, which
+    is exactly the gap the flag closes. The applied-vs-not monotonicity gap IS the before/after.
+
+Self-contained (httpx only). Config from env (source env.sh first).
