Split honesty into three milestones, defer five capabilities (V-719)

Owner's call. M1 is the turn path, M2 is memory he cannot correct, M3 is
step-up. They were one milestone and are three jobs: M1 and M2 touch
different code and owe different docs, and step-up is configuration, not
honesty. Nine milestones now.

Speaker recognition, smart home, bluetooth, model swap and self-update
move past v1. Bluetooth was on the v1 list and comes off it: no bluez on
the box. Their spec entries keep their DoD.

--no-verify: committing on master by the owner's call this session.

 ## Qwen3 resident model for router + phraser
 
-The target daemon uses the locally trained Qwen3-1.7B checkpoint for both
-routing and phrasing. Training is Qwen3 Base → RU CPT → joint persona/router

 deterministic floor.

 Telegram tokens are read from `deploy/telegram.env` (gitignored), expanded
 via `${VAR}` in the JSON config.
 
-**Routing is Qwen-first** with classifier fallback. The LLM router runs
-after stage-0 (exact-match grammar) and before the classifier cascade. On any
-error or parse failure, the classifier handles the utterance — the turn never

+CGO daemons (`mavend`, `mavsttd`, `mavttsd`, `mavenclient`) need the vendored
+toolchain wired through the Makefile. **Do not call `go build` on them bare**,
+and **do not hand-write the CGO preamble**. This box runs zsh, so an unquoted
+`-run Test*` dies on "no matches found" before `go` is reached. `make t` also
+carries `-count=1` and sets `MAVEN_ONNX_LIB`. Without that variable the four
+`TestONNX*` measurements self-skip and the run still prints `ok`.
 
 ```sh
-make build          # all 11 binaries
-make build-web      # single daemon (pure-Go ones: web/waked/poll/caldav build without CGO)
-make test           # go test -race across ./internal/... ./cmd/... with CGO env set
-```
-
-Run one package or one test with `make t`. **Do not hand-write the CGO preamble.**
-Past sessions pasted it about 390 times. That is where the shell-quoting failures
-came from. This box runs zsh, so an unquoted `-run Test*` or `--include=*.go`
-dies on "no matches found" before `go` is ever reached.
-
-```sh
-make t PKG=./internal/router/
-make t PKG=./cmd/mavend/ RUN=TestSimulator
+make build   # all 11 binaries. make build-web for one (web/waked/poll/caldav skip CGO)

+make analyze # staticcheck, deadcode and govulncheck. Not in `test`: all three need the network
 ```
 
-`t` carries `-race`, so a green `make t` cannot turn red under `make test`. It carries
-`-count=1`, so a cached PASS from before your edit is never mistaken for a result.
+**The static gates pass against a baseline, not against zero**
+(`scripts/analyzers/*.baseline`, reasoning in `docs/workflow.md`). A fix must
+delete its baseline entry, because the gate also fails on an entry whose finding
+is gone. **`make audit` is a git-grep inventory, not analysis.** Do not cite it
+as a reachability check.
 
-It also sets `MAVEN_ONNX_LIB`, which the hand-written recipe did not. The four
-`TestONNX*` measurements self-skip when that variable is unset. The run still prints
-`ok`. So every targeted eval done the old way reported the hash ratchet while reading
-as a real embedder score.
+## The daemons
 
-Pure-Go packages (`router`, `memory`, `mavweb`, …) also run under a plain `go test ./pkg/`,
-but `make t` works everywhere and is one thing to remember.
+Eleven binaries under `cmd/`, wired socket-to-socket over `internal/ipc`, not
+linked. `mavend` is the core and owns the DB and the IPC socket.
+`deploy/mavend.json` sets sockets, model paths and the phraser and embedder
+blocks, with `${VAR}` expansion from gitignored `deploy/telegram.env`.
+**`docker-compose.yml` runs five**: `mavend`, `mavsttd`, `mavttsd`, `mavweb`,
+`mavpoll`. Count against compose, not against `make build`. `mavwaked` runs on
+workpc under systemd. `docs/deployment.md` says who else is absent and why.
 
-## The daemons (`cmd/`)
-
-| Binary | Role |
-|---|---|
-| `mavend` | **Core.** Router, phraser, memory, reminders, digestion tick. Owns the DB + IPC socket. |
-| `mavweb` | HTTP UI + PWA (`/dash`, `/history`, `/trace`, `/notifications`, `/tools`); WebAuthn auth. Connects to mavend's socket. |
-| `mavsttd` | Speech-to-text (whisper.cpp, CGO). |
-| `mavttsd` | Text-to-speech (piper subprocess). |
-| `mavwaked` | Wake-word / VAD gate. **Not on homesrv** — see below. |
-| `mavenclient` | Voice loop client (mic → stt → core → tts). **Not on homesrv** — see below. |
-| `mavpoll` | Environment poller: netdata alarms, uptime-kuma, zenmoney, wireguard presence. Writes facts, sends nothing. Telegram is `internal/delivery/telegramsink`, not this. |
-| `mavcaldav` | CalDAV calendar sync. |
-| `mavmaild` | Mail reader (IMAP, read-only). Holds the IMAP password; core never sees it. |
-| `mavgpud` | GPU supervisor. **Runs on workpc, not homesrv** — own unit, `deploy/mavgpud.service`. Keeps llama-server loaded while the card is free (V-488). Maven never asks it for anything, it reads `/health` through `llm.Pair`. |
-| `mavupdate` | Not a daemon. Operator CLI a human runs on the box to deploy a new build. |
-
-Two more binaries have no Makefile target and are built with `go run` or `go build` when
-they are needed. Neither is deployed.
-
-| Binary | Role |
-|---|---|
-| `mavseal` | Recovery tool. Encrypts a live tmpfs working copy back to the ciphertext file when mavend was killed before `defer st.Close()` sealed it. |
-| `labelgen` | Runs the stage 0 grammars over utterances and prints JSONL, the training data for the routing heads (V-546). |
-
-Daemons are wired socket-to-socket, not linked. `internal/ipc` is the client/server wire
-protocol; the config in `deploy/mavend.json` (with `${VAR}` env expansion from gitignored
-`deploy/telegram.env`) sets socket paths, model paths, and the phraser/embedder blocks.
-
-**`docker-compose.yml` runs five: `mavend`, `mavsttd`, `mavttsd`, `mavweb`, `mavpoll`.**
-Count against compose, not against the table. Four of the nine daemons are absent, and each
-absence has a different reason.
-
-`mavmaild` and `mavcaldav` are commented out in compose, each with the reason written
-beside it: the first needs a mail account, the second a CalDAV account, and this box has
-neither. `mavcaldav` used to appear nowhere at all, which was an oversight; it became a
-recorded decision on 07-08-2026 (V-644). Two things ride on that absence and the block
-names them. Agenda questions route to `IntentQuery` at stage 0 (V-498) and the `calendar`
-query source then reads a table nobody writes. And `loop.State.CalendarBusy` is fed by the
-same facts, so the gate's "do not nag mid-meeting" is permanently false. Its password is
-read from a file (`-pass-file`, and `-render-pass-file` for the render collection), never
-taken as a flag value, which is the rule `mavpoll` and `mavmaild` follow too.
-
-**`mavwaked` and `mavenclient` are absent by decision, not oversight** (Vikunja #463,
-`docs/plans/17-where-the-voice-loop-runs.md`).
-homesrv has a microphone — it is a laptop — but it is in the wrong room, so a wake-word
-daemon there listens to nobody. They belong on a client machine where the owner is standing.
-
-**That machine is workpc** (owner's correction, 2026-08-05). This section used to say no
-such machine existed, which was written when the workstation was only a model host. It is
-where he sits most of the day and it has the microphone. `ipc.Dial` already takes
-`tcp://host:port?token=...` through the netaddr seam, so the two daemons need deploying,
-not building. V-515 is that deployment.
-
-Until they are deployed, **the wake word and the VAD gate are covered by unit tests and by
-nothing else**, and push-to-talk through `/dash` is what QA actually covers. Note that
-deploying them does not by itself prove a wake word: `mavwaked` gates on energy and has no
-keyword model (V-487), so the loop runs open until that lands.
+- **Passwords are read from files, never taken as flag values.**
+- **The voice wire is plaintext with no auth.** mavend's voice port stays on
+  homesrv loopback and reaches workpc over ssh. Do not LAN-bind it.
+  `SurfaceVoice` caps acts at L0, and L0 does not cap reading.
+- **A GPU service added beside mavgpud goes in `cmd/mavgpud`, never in systemd.**
+  The card needs one owner. A second unit made mavgpud evict llama-server every
+  few seconds and took the model arm down for eight minutes.

-- **Identity lives in Nexus.** Do not invent a local fact key for something Nexus

+## Routing
 
-## Routing — read this before touching the router
+**Read `docs/routing.md` before touching `internal/router/` or `queryWalk`.** It
+carries the reasoning, the measurements and every rule's why. A route produces
+two decisions. **Intent** is one of seven values. **Source** is where the answer
+lives and is read on `IntentQuery` alone. Score them separately. The cascade is
+stage 0 grammars, then the routing heads, then the resident model, then the
+classifier. Every stage may decline and the next one answers.
 
-`internal/router/` has TWO layered engines. **The LLM router is now the default and it is
-on in deploy** — this section used to say it was wired `nil`, which stopped being true on
-2026-07-31.
+- **The classifier is the floor, not dead code.** It answers when the resident
+  model is off, absent, or erroring. **Any model error falls through.**
+- **The stage 0 set lives in `router.StageZeroGrammars`**, and both `buildRouter`
+  and the eval fixture call it. Add a grammar there, in the right place, and read
+  the comment above the line you insert after. Do not restate the list anywhere.
+- **Go's `\b` is ASCII-only** and never fires after a Cyrillic letter. A Russian
+  pattern needs an explicit `(\s|[?!.]|$)`.
+- **`PraxisGrammars()` is the only path to Praxis**, not a faster one.
+- **`voice.embedder.heads_path` must never point at `model_path`.** Recall
+  depends on the resident e5-small scoring what it scored. Fine-tune a copy.
+  Refused at config load since V-692, symlinks included.
+- **Routing traces are retained 14 days**, enforced on write and again on start.
+- **Bump `tokenizerRev` on any change to what `encodeWord` emits**, so a
+  tokenizer fix triggers `ReembedAll` the way swapping the model file does.
+- **A new rung in the `runTurn` ladder needs its name in `preRouteLadder`**
+  (`cmd/mavend/decisiontrace.go`), or it is missing from the decision record.
 
-- **LLM router (the intended design, docs/rearchitecture.md):** the resident Qwen3-1.7B (`llmrouter.go`)
-  emits GBNF-constrained structured JSON, and the SAME model phrases replies. Embedder is
-  demoted from a routing gate to a RAG hint. Wired at `voice.go:214` via
-  `pickLLMRouter(cfg.Voice.UseLLMRouter(), llmClient)`; the flag is `voice.llm_router`
-  (`config.go`), `DefaultLLMRouter` is **on**, and `deploy/mavend.json` sets it `true`.
-- **Classifier cascade (the failure floor, not dead code):** `classifier.go` +
-  `embedder.go` nearest-neighbour over frozen seed phrases. It runs when the LLM router is
-  off, when there is no llama-server to talk to (`pickLLMRouter` logs that and degrades),
-  and on any per-turn LLM error. Do not delete it — routing by seed similarity is the known
-  cause of weak RU query handling, but a turn must never break on the model.
+**`queryWalk` takes query sources out and moves none** (`actions_query.go`). That
+is the safety argument and it is not negotiable. The table's order is
+load-bearing and carries "the owner's data first, then the world".
+`SourceUnknown` is the floor and walks the whole chain. A named destination
+removes only the sources marked `guesses: true`, so a source that looks rather
+than guesses is always asked. **The personal boundary is the one exception and
+it is deliberate.** It guesses, so naming `SourceWorld` drops it. **Only a stage
+0 grammar may drop it** (owner's call, V-666). `queryWalk` reads
+`Decision.SourceAnchored` for the source marked `boundary: true` and no other.
 
-Cascade order: `stage0.go` exact-match fast-path → LLM router (when non-nil) → classifier
-fallback. Any LLM error falls through to the classifier so a turn never breaks on the model.
+Judge a routing change against the classifier and the resident model, since

-**A stage-0 decision is slot-extracted too, since 06-08-2026** (V-572). `fillMatchedSlots`
-in `router.go` runs the stage-2 extractor over whatever a grammar built and fills only the
-slots it left empty — a matched value always wins, because the rule read a literal pattern
-and the extractor guesses. It did not run before, so `ReminderGrammar` handed the daemon
-`HasTime: false` for "напомни в 11:00 позвонить маме" and `missingFor` read the silence as
-absence and asked "Когда?". It applies to every grammar and is inert for all but the
-reminder: `Extract` fills Time, Fn and Key and nothing else, and the query, clock, agenda,
-feed, list, task and narrative rules all emit intents with no such slot. Benchmarked at
-20000x, a stage-0 query costs 3.7µs against 3.9µs before. **`Slots.Text` is deliberately not
-filled** — a grammar that left it empty meant it, and `agendaQueryBuild` hands the query
-chain the utterance itself. Fixture unchanged at 64/91, with "slots deferred to daemon"
-6 → 0.
+## Language: model output and Russian
 
-Measured on the 77-case RU fixture. **Re-measured 2026-08-02: the classifier scores 68.8%
-full accuracy at p50 16.6µs**, not the 36.8% at p50 31ms that stood here from
-`docs/evals/2026-07-31-model-bakeoff.md`. That older figure predates the stage 0 rules and the
-seed additions, both of which now score inside the classifier baseline. Qwen3-1.7B scores
-77.9% intent-only / 72.7% through the cascade. So the router buys about 4 points of accuracy,
-not a doubling, and the trade is worth re-arguing rather than assuming. **The ≈2.7s figure
-that stood here until 2026-08-02 was contention, not the model.** See `docs/evals/2026-07-31-routing.md` line 61, which measures the LLM router at
-p50 825ms / p95 1.2s / max 3.0s and the full cascade at p50 0.80-1.04s. Do not plan latency
-work off the bakeoff table.
+Both contracts are in `docs/language.md`. What must not be broken:
 
-**Re-measured 2026-08-05 on the fixture as it now stands, 91 cases** (V-320 item 2,
-`docs/evals/2026-08-05-routing-resident-model.md`): cascade + resident model scores
-**75.8% full / 80.2% intent-only at p50 1.19s / p95 1.65s**. That is a new baseline and not
-a movement, because 14 cases were added since the 77-case number above. The model alone
-scores 37.4% full against 61.5% intent-only, and the gap is slots rather than routing: it
-routes `reminder` and leaves the time to the daemon, which is what the contract asks. To
-re-run it, start a **second** llama-server on a fixed host port — the resident one binds
-`--port 0` inside the container and no host process can reach it.
+- **One parser for model text, `parseResponseMood`** in
+  `internal/phraser/parse.go`. Every phrasing path reaches it. Mood is an enum.
+- **The router prompt is a separate contract** over 7 intents, and
+  `llm/check_prompt_parity.py` keeps the Go and relabelling copies identical.
+- **Russian words are matched by three mechanisms and no fourth**:
+  `internal/lexicon` for closed classes, `internal/morph` for grammar, and
+  `cmd/mavend/topics.go` with the embedder for open sets. A regex whose output
+  is a fact or a route is the defect. A regex over structured input is not.
+- **Seeds are scoring data.** Editing one moves a recogniser and must be
+  re-measured against the `TestONNX*` tests, not eyeballed.
 
-**The numbers above are the homesrv floor, not the ceiling.** With the workstation up, routing
-completes through `llm.Pair` against gemma-4-12b and scores **84.4% full / 93.5% intent-only at
-p50 329ms** — better than the resident model and about 2.5× faster (`docs/evals/2026-08-02-workstation-gemma4-12b.md`,
-Vikunja #485). The workstation is never assumed up, so both sets of numbers are live. Judge a
-routing change against the classifier and the resident model, since those are what always answer.
+## Non-goals and hard constraints
 
-**The intended third engine is not a generative model** (owner's call, 05-08-2026, V-546,
-`docs/plans/18-routing-heads-on-e5-small.md`). Routing has a bounded output space, so it is
-classification, and the 118M multilingual-e5-small is already resident. Three heads on one
-forward pass: intent, mood, and BIO slot tags. Roughly 5e15 FLOPs to train, so 10 to 30
-minutes on the workstation. A 100M decoder from scratch is 10 to 20 GPU hours. Two things
-it buys that a decoder cannot. No grammar is needed, because a softmax cannot emit a value
-that does not exist. And max softmax is a calibratable confidence, where `Confidence: 1.0`
-was a hardcode. **Fine-tune a copy of the weights.** The resident embedder backs memory
-recall. Training it in place couples routing accuracy to recall@1, with nothing in the
-suite to name the trade.
+Not a nag, not autonomous.
+**The persona is feminine.** Russian self-reference takes feminine forms: `рада`
+not `рад`, `поняла` not `понял`. The owner is male and she speaks to him
+informally. Use "ты", singular, never "вы" or "ваш", and never "он" or "его".
+She talks TO the owner, not about him. Pet names such as "милый" are forbidden.
+The name "Ками" is not. `CheckAddress`, `CheckFeminine` and `CheckCringe` in
+`internal/phraser/eval/checks.go` enforce this, scored by `make eval-phrasing`.
 
-**Two of those heads are trained as of 08-08-2026, and they are not the three
-above** (V-661, `docs/evals/2026-08-08-routing-heads-two-head.md`). Intent and
-destination share one masked mean pool. Destination scores a mean **80.8%** over
-three seeds, best **29/33 (87.9%)**. The classifier cascade scores 12/33 and the
-cascade with gemma-4-12b scores 24/33, so a 118M encoder beats the 12B teacher it
-was distilled from. Read the best run as one seed and not a headline, because one
-case is 3 points on a fixture this small.
-Recall is 15/15 and world is 5/5. Intent is 93.6% mean over three seeds. That is
-**not** comparable to the 76.0% and 84.4% those two arms scored: a softmax has no
-clarify class, so the head's fixture is the 88 cases carrying an intent.
+**"Never phones home" is deprecated** (owner's call, 2026-07-31). She reads
+external sources, and `docs/world.md` carries that chain. What holds regardless:
 
-**A fourth head asks instead of guessing, same day** (V-661,
-`docs/evals/2026-08-08-clarify-head-four-head.md`). Clarify is not a value
-of intent, so a softmax cannot emit it. It is a second question over the
-same pooled vector: can Maven act on this at all. That is why the head's
-fixture was 88 cases and not 96. Over three seeds it catches **7.0 of the 8
-`want_clarify` cases and produces 2.3 false clarifies of 88**. The cascade
-today misses 1 and produces 2, so this is parity with no rules in front of
-it. Accuracy is the wrong number here and a head that never asks scores
-91.7%. Confidence is the other half. Max softmax over the intent head reads
-**0.851 where it is right against 0.604 where it is wrong**, ranking right
-above wrong in 83.4% of pairs. `Confidence: 1.0` was a hardcode, and this
-replaces it with a signal. The two are not the same signal: one says which
-intent is unclear, the other says the utterance carries too little to act
-on. **The fourth head is not free the way the third was.** Intent,
-destination and slot F1 each move down one to four points, inside the seed
-spread. `поужинал` is a false clarify on every seed, which is the same
-defect `thinSingleToken` was narrowed for on 2026-08-01.
-
-The corpus for it is generated, because every existing row is answerable by
-construction. **The router-prompt agreement filter cannot work here**, since
-`routeGrammar` has no clarify value and a generated line always agrees with
-itself. A gemma judge replaces it. The first judge called 24 of 40
-answerable rows underspecified, because it judged against a generic
-assistant rather than against Maven's contract.
-
-**Mood is cut, not deferred.** The enum describes her own reply state, not the
-speaker's emotion, and no dataset maps onto it.
-
-**A third head landed the same day** (`docs/evals/2026-08-08-slot-head-three-head.md`).
-BIO slot tags had no Maven-domain corpus, which was true of found corpora and
-false of made ones. `label_slots.py` distils spans out of gemma-4-12b under a
-GBNF closed over Maven's own five slots. A span survives only when it is a
-literal substring of the utterance, so the agreement filter costs no second
-call. 2178 spans over 1702 rows, 37 dropped, nothing unparsed. Three heads score
-intent **92.8%**, destination **82.8%** and slot span F1 **72.4%** over three
-seeds. The slot head is free: both other numbers move less than their own seed
-spread. Epoch selection reads the intent dev slice alone. Slot F1 is still
-climbing when it stops, which costs about 4 points.
-
-The MASSIVE warm-start of step 2 is worth nothing here. Stock e5-small ties it on
-intent and leads by a third of a case on destination. Nothing argues for keeping
-that step.
-
-The floor was a corpus defect and it is fixed. The first 120 floor rows carried
-one sentence shape, so the head named a destination where the fixture says walk
-the chain. Rotating six shapes took the floor 3/7 to 6/7 and destination 75.8% to
-80.8%. What is left is calendar at 3/6 on every seed, which training cannot move:
-the possessive agenda rules claim those cases at stage 0 and name nothing, so no
-label reaches the head. That is the same trade V-660 flagged and it wants the
-owner's call.
-
-**Nothing of this runs in Go.** The weights are `heads.pt` and `out/body_heads/`
-on workpc. Reaching the daemon needs an ONNX export and a caller. The resident
-e5-small must not be replaced by the copy, because recall depends on that file.
-
-`Confidence: 1.0` used to be hardcoded in `llmrouter.go`, so the LLM
-path could never ask for clarification (6/6 refusal cases missed on the fixture) — Vikunja
-#359. Fixed 31-07-2026 with structural signal (single-token utterance, keyless fact, act with
-no allowlisted fn) feeding the same stage-3 gate the classifier path already had — see
-`gateLLMDecision` in `router.go`. Note the second half of that bug: the LLM branch never
-consulted `r.threshold` at all, so a correct low confidence would have been discarded anyway.
-
-Re-measured on the fixture after the fix: **missed clarify 6/6 → 1**, at the cost of 3 false
-clarifies and 2.6pt of full accuracy (72.7% → 70.1%, intent-only 67.5% → 74.0%). Two of the
-three false clarifies are acts the model mis-routed and the gate caught — asking beats wrongly
-executing, so the fixture and the daemon disagree about what is correct there. The third,
-`"поужинал"`, was a real defect: the single-token rule was an English intuition and does not
-transfer to Russian, where one word is routinely a whole sentence.
-
-Narrowed 01-08-2026. `thinSingleToken` (`internal/router/singletoken.go`) still thins a bare
-one-word nominal — "вода", "бэкап" — but spares two classes: a closed lexicon of social and
-control singles ("привет", "спасибо", "стоп", "yes"), and any token carrying a Russian verb
-ending (past tense, 2nd person, reflexive), because a verb already contains its subject. Both
-tests are offline and cost nothing. Re-measured: **false clarifies 3 → 2, intent-only 74.0% →
-75.3%, full accuracy unchanged at 70.1%, missed clarify still 1.** The two remaining false
-clarifies are the act-with-no-allowlisted-fn arm of the gate, not this rule.
-
-Agenda questions taken off the model, 01-08-2026. `AgendaQueryGrammars` (`stage0.go`, wired
-after the clock rules in `buildRouter`) routes "что у меня сегодня", "во сколько у меня
-встреча" and anything naming a calendar to `IntentQuery` at stage 0. They were going to
-`IntentSystem`, where `replySystem` has no agenda arm and answered "пока не умею" — the
-fixture had said `query` since ru-query-019 was written. Measured: **full accuracy 70.1% →
-72.7%, intent-only 75.3% → 77.9%, calendar 0/2 → 2/2**, clarify counts unchanged. Note that
-Go's `\b` is ASCII-only and never fires after a Cyrillic letter; the pattern needs an
-explicit `(\s|[?!.]|$)`.
-
-Two more shapes taken off the model, 04-08-2026 (V-498). `rest-of-day-query` inside
-`AgendaQueryGrammars` claims "что дальше?" / "what's next", and `NarrativeQueryGrammar`
-(`stage0.go`, wired **last** in `buildRouter`, after the capture marker) claims "расскажи про
-X", "объясни X", "опиши X". Neither carries a question mark or an interrogative, so the model
-called both `IntentFact`; the write was caught downstream by `IsQuestionShaped`, so this was a
-latency and fixture defect, not a correctness one. The narrative rule reads the same
-`narrativeRequests` lexicon `IsQuestionShaped` reads, and declines `chatNarrativeTopics` — a
-joke, a bedtime story, herself — because the query chain has no source that answers those.
-New fixture cases ru-query-024 and ru-query-025. Classifier + ONNX baseline **56/80 (70.0%) →
-58/82 (70.7%)**, no case regressed, no new false clarify. The LLM arm was not measured (no
-llama-server in that run), so judge it again before quoting a cascade number.
-
-Praxis taken off the model, 05-08-2026 (V-516). `PraxisGrammars()`
-(`internal/router/praxis.go`, wired in `buildRouter` before the capture marker because
-"отметь" is a capture verb) fills `Slots.Fn` with a Praxis capability name.
-**These grammars are the only path to Praxis, not a faster one.** Measured
-2026-08-05 with the resident model as router (V-517,
-`docs/evals/2026-08-05-reach-llm-router.md`): the model alone reaches Praxis
-**0/12**, the same as the classifier alone, because nothing in the router
-prompt names a Praxis capability and there is no string for it to write.
-Through the cascade it is 11/12. Deleting these rules costs every point. Praxis reach
-was **0/12 and structurally so**: `handlePraxisAct` compares `Slots.Fn` to a capability
-alias, and that slot is filled from the deployment's enabled tool names, which no Praxis
-alias is on. Measured **16/30 → 27/30 overall, praxis 0/12 → 11/12, lifecycle 0/5 → 5/5**
-(`docs/evals/2026-08-05-praxis-reach.md`). Two rules to know before editing: a **stative**
-lifecycle word ("готово", "принято") needs an item named beside it, while a bare
-**imperative** ("закрывай") may ask which one. The bare arm additionally requires that
-the sentence name no object of its own, or "закрой шторы в комнате" goes to Praxis instead
-of the house. A demonstrative ("отметь это как сделанное") resolves against
-`h.surfacedItems` only when exactly one item was spoken. Otherwise the turn goes back to
-the cascade rather than transitioning the wrong item.
-
-**Who claimed a turn is now recorded, and so is who did not** (V-564, umbrella
-V-558). Arbitration between the claimants on the utterance stream is order,
-hardcoded in the pre-route resolver ladder, in `buildRouter` and in
-`querySources`. `internal/decision` records one `Record` per turn: every
-claimant, what it would have made the turn, the score it reported, and whether
-it won, declined, lost on score, was thinned by a gate or was **never asked**.
-The record rides the context, the same seam `querysource.go` uses, so a claim
-site cannot change a route and a context with no record costs nothing. It is
-installed in `runTurn`, so the mic, telegram and the web all leave the same
-trail. Storage is a 25-turn in-memory ring on the handler (`decision.Ring`),
-read over `ipc.TurnDecisions` and rendered as the second table on `/trace`.
-**It also persists, since 06-08-2026, and that reverses what this section used to
-say** (V-629, `docs/plans/21-persisting-the-routing-trace.md`). The old rule was
-that nothing persists, because a turn record is read minutes later or never. The
-owner reversed it: the routing heads (V-546) cannot be fitted or calibrated
-without real utterances, and 9 of the 31 modes in `internal/modes` have no seed
-example at all. The ring did not move. It is still what `/trace` reads and still
-what a test with no store gets. `cmd/mavend/routingtrace.go` is a second sink
-beside it, writing `routing_traces` (migration #23). The utterance is stored in
-clear, because a 384-dimension vector of a short sentence is substantially
-recoverable and storing vectors instead would be a privacy claim we cannot
-support. What makes it safe is the same thing that makes the fact store safe.
-Retention is 14 days, enforced on write and again on start, so a box that goes
-quiet does not keep every row. Nothing reads it outward, and the rule
-that his notes and facts are never search input covers this table. `Store.Wipe`
-deletes it with everything else. A correction (V-630) is promoted out into a
-seed-shaped row in `routing_labels` (migration #24) and kept, because a label is
-not a transcript. The transcript still expires. The gesture that writes one is
-two buttons beside the reply on `/chat`, reached over `ipc.CorrectTurn` and the
-trace id that now rides back on `ipc.ChatReply`. A turn marked wrong with no
-target is a usable negative, so naming the intent is never required. The target
-is one of the seven intents and never free text. **All three reaches offer it as
-of 06-08-2026**, and this section used to say only `/chat` did. Voice is the
-`repair` rung, which has read spoken corrections since V-455 and now writes the
-durable label beside the classifier seed it always wrote; a spoken negative with
-no target is its own rung, `repair-negative` (V-636, `docs/plans/22-correcting-a-turn.md`).
-Telegram is an inline keyboard under the reply, and it needed the chat to become
-readable first — **telegram is no longer outbound only** (V-637,
-`docs/plans/23-inbound-telegram.md`). The poller is dark unless the `telegram`
-block says `intake`, it long-polls because the box takes no inbound connections,
-it accepts `chat_id` and no other sender, and it drops whatever queued while the
-daemon was down. It reaches the daemon through `ipc.CoreAPI` alone, so a chat
-turn takes the path `POST /api/chat` takes. Note that the turn source is still
-`tap:text` for both, so provenance cannot tell a chat turn from a typed one.
-Adding a rung to the ladder
-in `runTurn` means adding its name to `preRouteLadder` in
-`cmd/mavend/decisiontrace.go`, or that rung is silently missing from the record.
-
-**A route now says where the answer lives, not only that the turn is a question**
-(V-655, 07-08-2026). `query` was a shrug. The cascade sorted an utterance into one of
-seven intents, with stage 0, the resident model and the classifier behind it. Then
-`IntentQuery` handed the turn to `querySources` in the daemon. That is twenty-two branches
-deciding by seed similarity in a fixed order. It has no fixture and no accuracy
-number, no model arm and no floor. `Decision.Source` (`internal/router/source.go`) is
-the second half of the route. Twelve destinations, not twenty-two. The three recall
-passes plus `fact-by-key` are one destination from outside. So are search, Kiwix and
-the URL reader.
-
-**`SourceUnknown` is a real value and it is the floor.** Nothing named a destination,
-so the daemon walks the whole chain. That is byte-for-byte what shipped before the
-field existed. The classifier arm names nothing, so a box whose model is down routes
-queries exactly as it did.
-
-`queryWalk` in `cmd/mavend/actions_query.go` takes sources **out** and moves none.
-That is the safety argument and it is not negotiable. The table's order is
-load-bearing. Every comment on it argues a reason between two sources, and above all
-it carries "the owner's data first, then the world". Naming `SourceWorld` does not
-send the turn outside on its own. His notes and his facts still run first, because
-they look rather than guess.
-
-**The personal boundary is the one exception and it is deliberate.** It guesses,
-so naming `SourceWorld` drops it. That is what stops it answering "кто такой
-Линус Торвальдс?" with "не нашла у тебя такой записи", which it did on
-2026-08-07. The cost is that a destination a model wrote can now take the
-boundary off a turn. A question about him that the model calls `world` reaches
-SearXNG, where today the boundary stops it. Only the utterance leaves the box,
-never his notes or history, so this widens what is asked and not what is sent.
-`TestNamingRecallKeepsTheBoundary` pins the other half: naming `SourceRecall`
-keeps the boundary in front of the world. Whether a model may drop it at all is
-the owner's call and has not been made.
-
-What comes out is only the sources that **guess**. Those decide a turn is theirs by
-cosine against frozen seeds, then answer whatever they claimed. They hold no table
-that could come back empty. Weather is the pure case and has no local data at
-all. It was measured on the box on 2026-08-07
-(`docs/evals/2026-08-07-week-of-usage.md` section 4). It answered both "что такое
-TCP?" and "сколько будет 17 на 23?" with "для какого города?". The feed answered "какой у меня любимый язык?" with kernel headlines.
-The personal boundary answered "кто такой Линус Торвальдс?" with "не нашла у тебя
-такой записи". A source that guesses is marked `guesses: true` in the table. One that
-looks is not, and it is always asked.
-
-Stage 0 fills the destination where a rule already knows it. `WorldQueryGrammars()`
-(`internal/router/worldquery.go`) claims "что такое X" and "сколько будет 17 на 23".
-It is wired after the agenda rules and **before** the feed and list rules.
-"что такое лента" is a definition question, and the feed rule would take it on the
-noun alone.
-`calendar-query` and `event-time-query` name the calendar. The possessive agenda rules
-deliberately do not. "что у меня в списке покупок" matches `agenda-query`, and naming
-the calendar there would take the list source off the turn.
-
-Fixture unchanged at **69/91 classifier+ONNX**, measured both sides. That is the
-expected result, because it scores intent and no case here changes intent.
-
-**The destination has its own fixture and its own number as of 08-08-2026**
-(V-659, `docs/evals/2026-08-08-destination-fixture.md`). This section used to say
-it had neither. `want_source` on `eval.Case` is a pointer, because the destination
-has three states and a bare string has two. Absent is every intent but query,
-which never reaches `queryWalk`. Present and empty is the `SourceUnknown`
-contract: name nothing and walk the chain. Present and named is a destination the
-route must produce. Thirty-three of ninety-six cases carry one.
-
-A destination miss does **not** fail the case. It lands in `Outcome.SourceReason`
-and never in `Reasons`, so `Accuracy` and `IntentAccuracy` mean what they meant
-and `SourceAccuracy` is a second number over the labelled cases only. Intent and
-destination are two decisions, and one number hides which one moved. A route that
-lost its intent scores no destination hit, or a clarify would satisfy an empty
-label for free.
-
-Measured classifier+ONNX: intent **73/96 (76.0%)**, destination **12/33 (36.4%)**.
-The split is the finding. World is 5/5, because a stage 0 rule names it. The
-`SourceUnknown` floor is 5/7. Calendar is 2/6, because the possessive agenda
-rules deliberately do not name it. And **recall is 0/15, because nothing
-anywhere names it**. Those turns are still answered, since the chain walks
-recall early. Recall is the number the fourth head has to move.
-
-Seven cases assert the floor and five of them are homelab operations. They
-cluster because `SourceRecall`, `SourceNetwork` and `SourceAttention` overlap on
-every question about the box. The other two are `ru-query-005` and
-`ru-query-014`. No query source reads the reminder store, and a deadline could
-sit in tasks, the calendar or Praxis. `mavpoll` writes its netdata and uptime-kuma
-observations into the fact store recall reads. That is a finding about the enum,
-not a gap in the labelling. The owner confirmed all seven floor labels on
-08-08-2026, so they are a decision rather than an agent's guess.
-
-`baselineGrammars` in `eval_test.go` mirrors `buildRouter` and had drifted:
-`WorldQueryGrammars` was wired into the daemon by V-655 and not into the mirror,
-so the fixture scored a grammar set nobody runs. Fixed by V-659, worth 3 points of
-destination and nothing else. Check that function when adding a grammar.
-
-**The model arm landed the same day** (V-660,
-`docs/evals/2026-08-08-destination-model-arm.md`). `routeGrammar` carries a
-`source` rule closed over `router.Sources` plus the empty floor, so the model
-cannot emit a destination that does not exist. The prompt lists the twelve in
-Russian and says `""` is a normal answer to give often. `LLMRouter.Route` reads it
-back through `ValidSource` and on `IntentQuery` alone. Against gemma-4-12b on the
-workstation the cascade scores destination **24/33 (72.7%)** with intent unmoved
-at 84.4%, and **recall goes 0/15 to 14/15**. The resident Qwen3-1.7B is
-unmeasured, because it binds `--port 0` inside the container.
-
-**Stage 0 now costs four destination points.** It did not before. The four cases
-the cascade loses and the model alone wins are all calendar. The possessive
-agenda rules claim them first and name nothing on purpose. That caution was free
-while nothing downstream could name anything either. It is not free now, and the
-fix is the owner's call rather than a quiet edit.
-
-The last arm is V-546. Intent, mood and BIO slot tags were already three heads on
-one forward pass of the resident e5-small. Destination is a fourth head on the
-same pass, and 72.7% from a 12B teacher is the label source for training it.
-
-## LLM output contract
-
-All phrasing paths emit `{"response":"...","mood":"..."}`, with fallback to plain text when
-the model skips the JSON. **One parser, `parseResponseMood` in
-`internal/phraser/parse.go`**, and every path reaches it: the six `LLMPhraser` methods,
-`PhraseWorld`, and `Replier.PhraseReply`, which `cmd/mavend/replier_llm.go` wraps — that file
-holds the stub fallback and no parsing of its own. The legacy `{"body","summary"}` fallback
-was deleted on 2026-08-06 (V-397): it was the contract before `{"response","mood"}` replaced
-it, no prompt asks for that shape, the GBNF cannot emit it, and no test covered it.
-Mood is a fixed enum. Router prompt is a separate contract:
-`[{"intent":<enum>, key?, value?, text?, verb?}, ...]`, 7 intents (`fact, reminder,
-note, query, act, chat, system`). `llm/check_prompt_parity.py` in the training
-workspace enforces that the Go and relabelling prompts remain identical.
-
-## Russian patterns — three mechanisms, no fourth
-
-Hand-written Russian stem patterns were swept out on 2026-08-04 (owner's call: not a
-pattern, and the resident model cannot be asked per turn either). A regex whose output is a
-fact or a route is the defect; a regex over structured input — HTML, MIME, JSON, a URL, an
-argv list — is not. Before writing a Russian word list, pick one of these:
-
-- **`internal/lexicon`** — closed classes, in `lexicon_ru_v1.json`. Interrogatives,
-  capture verbs, reminder verbs, cardinals, day offsets, parts of day, weekdays, months,
-  spoken hours. Editing a word is a data change, and there is exactly one copy: months used
-  to live in three files. Cardinals carry the oblique forms, because a spoken time declines
-  and `в семь` / `к семи` are one hour.
-- **`internal/morph`** — grammar, from the vendored golem Russian dictionary. `IsVerbForm`
-  and `SameWord`. Note that lemma matching is BROADER than stem-plus-one-ending, so a verb
-  slot that means the imperative must be matched exactly — `говори` and `говорил` are one
-  lemma and only one of them is a command (`cmd/mavend/quiet_toggle.go`).
-- **`cmd/mavend/topics.go` and the embedder** — open sets, where the question is what a
-  turn is ABOUT. Frozen seeds per subject plus a real `other` class, scored against the
-  turn's own query vector. Same shape as the personal boundary in `personalboundary.go`,
-  with one difference: a topic must clear the runner-up by `topicMargin`, because a false
-  claim here spends a network scan rather than one honest "не знаю". The old keyword tests
-  stay as the offline floor and may remain narrow, since they are no longer the only answer.
-- **The ecosystem trio** — when the answer is not in the utterance at all. Identity is
-  Nexus's, never a local pattern.
-
-Seeds are scoring data. Editing one moves a recogniser and must be re-measured against the
-`TestONNX*` tests, not eyeballed.
-
-## Non-goals (hard constraints)
-
-Not a nag, not autonomous. Maven's persona is **feminine** — Russian
-self-reference must use feminine forms — `рада`, not `рад`; `поняла`, not `понял`. The owner
-is male and is addressed informally: "ты", singular, never "вы"/"ваш" and never "он"/"его"
-(she talks TO the owner, not about the owner). Pet names ("милый", "дорогой") are forbidden; the name
-("Ками") is not. The eval enforces this: `CheckAddress`, `CheckFeminine` and `CheckCringe` in
-`internal/phraser/eval/checks.go`, scored by `make eval-phrasing`.
-
-**"Never phones home" is DEPRECATED** (owner's call, 2026-07-31). It used to be a hard
-constraint and it is not one any more: a 0.8B — and a 1.7B — does not know enough to answer
-world questions, so she needs to read external sources. What replaces it:
-
-- **No telemetry, no cloud model, no third-party account.** That part never changes. Nothing
-  about Maven is reported to anyone, and inference stays on the box.
-- **The owner's data first, then the world.** Every source that reads the owner's facts, notes, calendar,
-  tasks or house runs before anything outside, and the personal boundary sits between them.
-  Reading beats recalling for a small model.
-- **In the world, live search leads and the ZIMs are the fallback** (owner's call,
-  2026-08-02). A self-hosted SearXNG (`search` block) answers first; the Kiwix ZIMs on
-  homesrv answer when the search is empty, unreachable, or the line is down.
-  **Verified with the line down on 2026-08-05** (V-508,
-  `docs/evals/2026-08-05-kiwix-offline-fallback.md`): a stopped SearXNG costs nothing,
-  the ZIM answers in the same turn budget. A blackholed host cost 8 seconds the owner waited
-  through. So the connect phase alone is capped at `dialTimeout` (1.5s), while a slow
-  instance that did connect keeps the full 8. **A Russian question reads
-  `wikipedia_ru_all_maxi_2026-02` verbatim** through `kiwix.book_ru`. The RU→EN rewriter
-  is the workaround for an English book and is skipped there. Kiwix catalog names come
-  from the filename, not the `<name>` field.
-  `Response.Empty()` is the whole gate and there is no quality threshold in front of it:
-  the three signals one could read were measured on 2026-08-05 and none of them separate a
-  real question from an invented one. Token overlap would cost "столица Франции" its
-  answer, because the answer is Париж and that word is not in the question. See
-  `docs/evals/2026-08-05-search-quality-signals.md` (V-539). **Which query source claimed
-  a turn is readable on `/chat`** as a badge beside the reply, carried on
-  `ipc.ChatReply.Source` and noted by `noteQuerySource` in `cmd/mavend/querysource.go`. It
-  rides the context, so `handleText` keeps the one string signature the mic, telegram and
-  the web share.
-- **External search is allowed and off unless configured**, like the weather and telegram
-  capabilities. The code default is still off. `deploy/mavend.json` now ships a `search`
-  block (owner's call, 2026-08-02), so it is on for this box and deleting the block turns
-  it off again.
-- **The owner's notes and facts are never search input.** Looking up why the sky is blue and
-  sending the owner's stored personal notes to an upstream engine are different acts. Only the utterance goes
-  out, never the persona block, history, or matched notes.
-
-## Web UI conventions
-
-Server-rendered pages share `cmd/mavweb/static/ui.css` (served at `/ui.css`) and the shell
-partial in `cmd/mavweb/shell.html`: a page opens with `{{template "shellTop" "<page-key>"}}`
-and closes with `{{template "shellBottom"}}`, and the key marks the active sidebar link.
-Every page is its own embedded `.html` file next to `main.go` — no page markup lives in Go,
-and the sidebar is data (`sidebarSections`, `pageIcon`) the template renders. No
-per-page `<style>` beyond true one-offs. Wrap every table in `<div class=scroll>` so wide
-data pans on a phone. Local preview + headless screenshot recipe is in `AGENTS.md`.
-
-## Vikunja
-
-This repo is project **Maven** (ID 2) in Vikunja. MCP: `http://localhost:9100/mcp` (or
-`http://192.168.1.104:9100/mcp` from workpc). Feature/bug/deploy tasks go there.
-
-Vikunja is the durable task store. A task holds the goal, the constraints and the
-assumption ledger. Work without a task id is work nobody can resume, so a session that
-has no id asks for one before it starts.
-
-The MCP tool schemas are deferred, so load the four you actually use in ONE call at the
-start of a session rather than one lookup per first use:
-
-```text
-ToolSearch("select:mcp__vikunja__list_tasks,mcp__vikunja__get_task_details,mcp__vikunja__create_task,mcp__vikunja__update_task")
-```
-
-**Close a finished task with `done: true` and nothing else** (owner's call, 07-08-2026).
-Do not write a completion summary into the description on the way out. It is lost anyway,
-and the durable record is the commit messages and the merged PR. Note that `update_task`
-carrying a `description` resets `done` to false, which is why a write-up ever took two
-calls.
+- **No telemetry, no cloud model, no third-party account.** Inference stays on
+  the box and nothing about Maven is reported to anyone.
+- **The owner's data first, then the world.** Every source reading his facts,
+  notes, calendar, tasks or house runs first, and the personal boundary sits
+  between them and anything outside.
+- **His notes and facts are never search input.** Only the utterance goes out,
+  never the persona block, the history, or matched notes.

 ## Session workflow
 
-`~/.local/bin/task` owns the branch, the commit identity and the PR. One task, one
-session, one PR.
+`docs/workflow.md` carries the five stores, the doc tiers and the guards. One
+task, one session, one PR. `/pickup` opens a session and `/wrap` closes it. Wrap
+at roughly half context rather than letting the session compact.
 
 ```sh
 task start <vikunja-id>   # branch off origin/master, write TASK.md, fetch review comments
 task pr                   # push, open or refresh the PR, label Vikunja, notify
-task comments             # re-pull this branch's review comments into .task/
+ToolSearch("select:mcp__vikunja__list_tasks,mcp__vikunja__get_task_details,mcp__vikunja__create_task,mcp__vikunja__update_task")
 ```
 
-Around that, `/pickup` opens a session and `/wrap` closes it. Wrap at roughly half
-context rather than letting the session compact.
-
-Five stores, and each one owns something the others must not hold:
-
-| Store | Holds | Lifetime |
-|---|---|---|
-| Vikunja task | goal, constraints, assumption ledger, status | durable |
-| `CLAUDE.md`, `AGENTS.md` | what an agent must know before touching code | durable |
-| `docs/` | design, measurements, decisions | durable |
-| `TASK.md` | the brief for this branch, written by `task start`, immutable | one branch |
-| `HANDOFF.md` | only what the next agent needs to resume | one session |
-
-`TASK.md` and `.task/` are excluded through `.git/info/exclude`. `HANDOFF.md` is
-gitignored and injected at session start. If a line in the handoff would still matter
-next week, it is in the wrong file.
-
-Docs are tiered by path, so staleness is visible from the filename. Files directly under
-`docs/` are living and carry a `Last verified: <date> @ <sha>` line. Files under
-`docs/evals/` are dated measurements and are never edited after the day, so a newer
-number is a new file. Files under `docs/archive/` are dead and read by nobody by default.
-
-## Git guards
-
-Two hooks in `.githooks/`, tracked, wired with `core.hooksPath`. Fresh clone:
-
-```sh
-git config core.hooksPath .githooks
-```
-
-- `pre-commit` refuses master, and refuses more than 300 changed lines in non-markdown
-  files. Markdown is exempt and may land as one batch.
-- `commit-msg` requires the subject to end with `(V-<id>)`. `V-` and not `#`, because
-  Gitea autolinks `#123` to a Gitea issue, which is the wrong tracker.
-
-Two more guards live outside the repo, in `~/.claude/hooks/`. `diff-budget.sh` blocks
-further edits past 600 changed lines on a `task/` branch. `prose_lint_hook.py` checks
-prose on every write. Both measure against `origin/master`, so a local master that is
-ahead of the remote makes the diff budget read high.
-
-`--no-verify` exists. Using it means saying why in the commit body.

+# Maven completion journal
+
+This journal tracks the autonomous completion goal started on 2026-08-13. It
+is an operational index, not a substitute for living subsystem documentation,
+dated evaluations, Vikunja tasks, or focused caveat entries.
+
+## 2026-08-13 — baseline and backlog reconstruction
+
+Goal: make Maven usable end to end with every current and planned feature
+wired, tested, and polished. Completion requires clean automated gates and
+successful sessions across local, degraded-ecosystem, and integrated modes.
+
+Initial observations:
+
+- `HEAD` is `2cf8b7e`, identical to both local and remote `master`, while the
+  checked-out branch is the stale `task/704-...` branch.
+- The worktree already contained staged documentation/evaluation changes,
+  staged transcript deletions, an unstaged `deploy/mavwaked.service` change,
+  and untracked `deploy/asoundrc`. These are pre-existing work and are being
+  preserved and validated before any commit.
+- The repository has no prior goal journal. Durable subsystem facts continue
+  to belong under `docs/`; unresolved limits continue to belong under
+  `docs/caveats/` with a task and revisit trigger.
+
+Work streams started:
+
+- Vikunja project 2: inventory every open task and recover acceptance criteria.
+- Repository: compare feature plans, caveats, routing/ecosystem contracts, and
+  implementation.
+- Verification: run build, race tests, simulator, analyzer gates, and inspect
+  skipped hardware/model evaluations separately.
+- Runtime: exercise the web, IPC, voice, model, and sibling-service paths with
+  real local dependencies where available and explicit degraded-mode probes
+  otherwise.
+
+References: `docs/workflow.md`, `docs/qa.md`, `docs/ecosystem.md`,
+`docs/routing.md`, `docs/caveats/CLAUDE.md`, and Vikunja Maven project 2.
+
+### Backlog correction
+
+The first Vikunja page was accidentally read without a `done: false` filter and
+mixed closed history into the working set. Re-querying all pages strictly open
+produced 127 records: 89 implementation-open, 20 shipped-but-QA-open, 12
+external/owner gates, and 6 duplicate or stale-open records. Closed tasks are
+used only as commit provenance; they are not work to redo. V-704 was the only
+open hanging task and was closed after its measured correction landed.
+
+### Model-aware baseline
+
+The ordinary `make test` passed but does not set `MAVEN_ONNX_LIB`, so model-aware
+tests can self-skip. The explicit ONNX boundary gate exposed V-702/V-703: the
+held-out `я рассказывал тебе про байкал?` was the sole miss at 28/29. A
+three-neighbour class score fixed the semantic collision without adding a word
+pattern or copying the held-out sentence. Boundary is now 29/29 and the adjacent
+topic gate remains 43/43. Measurement:
+`docs/evals/2026-08-13-personal-boundary-neighbourhood.md`.
+
+That narrow result was not accepted as the completion gate. A second agent
+wrote a balanced 72-case RU/EN matrix across remembered speech, possession,
+narrative, proper nouns, personal preambles, and advice/current questions. It
+contains no production seeds and no Baikal paraphrase. The top-three candidate
+scores only 61/72 (84.7%); top-two reaches 62/72, one-neighbour 56/72, and a
+whole-class centroid 54/72. V-702 therefore remains open while a principled
+classifier is developed against the independent matrix. The 29/29 measurement
+describes the narrow regression set, not general boundary quality.
+
+### Live delivery incident
+
+The five-service compose stack was running, but a due reminder was being
+re-phrased and retried through ntfy every tick. The sink returned HTTP 403 each
+time. Only secret names were inspected: the configured ntfy and workstation
+token variables were absent from the deployed environment file; no secret
+values were read into this journal. The durable outbox records each failed
+attempt, but the retry path has no backoff or alternate channel and spends the
+resident model again before every failure. This is active V-651 behavior, with
+the repeated-phrasing shape related to V-687.
+
+V-715 now owns the incident acceptance criteria. In the working tree, phrases,
+collapsed-group identity, attempts, and next-attempt time are durable; definite
+failure backs off from one minute to a capped hour; retries and restarts reuse
+the exact phrase; and away delivery tries ntfy then Telegram, stopping at the
+first success. The committed deployment explicitly disables the uncredentialed
+ntfy block. Independent review added a real occurrence key for collapsed
+bundles, suppresses crash-ambiguous attempts from automatic replay, classifies
+HTTP 401/403 as permanent, blocks permanently unreachable reminders visibly,
+and commits the successful outbox result plus every collapsed original in one
+SQLite transaction. The store, delivery, IPC, loop, config, and mavweb race
+suites pass. A live rebuild and one-time delivery of the existing backlog are
+still required before V-715 is closed.
+
+### Explicit integration enablement
+
+V-691's deployment boundary was audited against every `${VAR}` reference. The
+canonical `deploy/telegram.env.example` now names Telegram, ntfy, workstation
+model, workstation STT, Home Assistant, ambient, CW2, and database-key inputs.
+Enabled Telegram, ntfy, ambient, non-loopback workstation model, and
+non-loopback workstation STT paths refuse missing credentials; each arm has an
+explicit disabled state. The live config disables the currently uncredentialed
+ntfy and workstation-model arms while retaining the separately credentialed
+STT arm. CW2 also refuses a non-loopback bind without its token.
+
+Focused Go race suites, the Python CW2 startup contract, deploy-config drift
+test, secret-expanded config validation (values not printed), and
+`docker compose config --quiet` pass. The workpc is unreachable from this host,
+so installing the updated CW2 script there remains an external deployment step;
+the affected model arm is explicitly dark rather than ambiguously half-live.
+
+### Traceable web failures
+
+V-689 gives every mavweb response a server-generated request ID and routes
+every handler failure through one sanitized problem envelope. Stable error
+codes and the request ID reach the browser; the wrapped internal error reaches
+only the server log beside the same ID. Degraded inline panels use stable public
+text rather than backend paths or tokens, and direct ecosystem reads propagate
+the web request ID as their correlation ID. An AST guard prevents new production
+handlers from bypassing the contract with `http.Error`. The full mavweb race
+suite passes, including disclosure, untrusted-ID, log-join, and propagation
+tests.
+
+### Bounded external responses
+
+Three audit defects were repaired and committed directly to `master`:
+
+- V-608 (`d7e8804`): llama completion responses are capped at 1 MiB, including
+  the LAN workstation seam.
+- V-675 (`459fe7a`): remote STT requires nonblank text and an explicit finite
+  confidence in `[0,1]`, caps JSON at 64 KiB, and falls back to mavsttd on a
+  malformed HTTP 200.
+- V-676 (`7d0250a`): Open-Meteo geocoding and forecasts are bounded, required
+  fields are nullable/validated, and coordinates/weather values are range
+  checked so `{}` cannot become plausible zero-degree weather.
+
+Each focused race suite passed and each task was closed only after the commit.
+
+### Transport shutdown
+
+V-679 (`de61b75`) adds the listener's `done` channel to TCP `Accept`. A
+concurrent-close test holds a silent peer in handshake and proves an in-flight
+accept returns `net.ErrClosed`; the race test passed twenty consecutive runs.
+
+V-688 (`80b6068`, caveat retirement `a0e6643`) bounds the browser push-to-talk
+body at ten minutes of mono PCM and configures header, idle, and read limits on
+the web server. The unused `/ws` handler was removed instead of retaining a
+second unauthenticated streaming transport with no browser caller. Focused race
+tests prove the exact-size request succeeds and an oversized request returns
+HTTP 413.
+
+### Conversation continuity
+
+V-542 (`da9114b`) repairs the five-turn monitor conversation without changing
+single-turn intent classification. Exact user utterances are now persisted
+separately from normalized intent slots and retained in chronological order.
+An anaphoric query with live transcript context reaches the chat path, while
+non-anaphoric sources are unchanged and acts stay fail-closed. An explicit
+conversation opener extends the session lifetime through later fact/query/chat
+routes without suppressing the grounded fact write.
+
+The deterministic scenario now names the monitor in all four contextual
+replies, proves that the original raw turn reached `PhraseChat` four times,
+stores the fact once, and produces zero unsolicited sends across five turns and
+one tick. Focused race tests passed for `cmd/mavend`, `internal/dialogue`,
+`internal/router`, and `internal/lexicon`. Measurement:
+`docs/evals/2026-08-13-conversation-continuity.md`.
+
+### Personal-data boundary
+
+V-702 replaces the narrow nearest-neighbour privacy gate with a frozen,
+class-balanced logistic head over multilingual-e5-small. It introduces no
+lexical exception and leaves the decision threshold at 0.5. Historical
+regressions score 29/29 and the balanced 72-case RU/EN fixture scores 72/72.
+
+The first 24-case challenge found one private-configuration miss. That result
+was treated as model-selection data rather than advertised as independent
+proof. Shrinkage LDA and an LDA/logistic ensemble repaired it but regressed the
+72-case gate, so both were rejected. Increasing the logistic L2 coefficient
+from 0.0001 to 0.0003 repairs the miss while improving four-fold corpus
+cross-validation from 97/104 to 99/104 and whole-shape holdout from 91/104 to
+92/104. A fresh 24-case challenge written only after that head was frozen scores
+24/24 at minimum signed probability margin +0.1718. The original challenge is
+also 24/24 but its +0.0001 edge remains documented as a regression, not fresh
+evidence. Full measurement:
+`docs/evals/2026-08-13-personal-boundary-linear-head.md`.
+
+During the audit, running multiple ONNX-backed tests in one `go test` process
+showed that only the first initializes; later tests self-skip because the
+runtime is process-global. All V-702 figures were therefore rerun in separate
+processes. V-716 tracks fixing that harness gap rather than hiding it in this
+feature.
+
+### Forced dialogue and repair state
+
+V-573 closes all four repair seams exposed by the dialogue contract: a
+correction wins before a parked clarify answer; a repaired decision is checked
+for required slots before acting; a request completed through clarification is
+correctable; and declined or stale repairs do not prematurely spend the repair
+pointer. Same-intent corrections are handled explicitly without redoing the
+action, so their prose cannot route fresh and overwrite the retained pointer.
+
+The independent state audit found two deeper stack losses. A handled repair
+could leave an older question silently parked with its old TTL, and a repaired
+request needing clarification could overwrite—or, on completion, delete—the
+older flow. Repairs now suspend and audibly resume live questions, repaired
+questions push onto the bounded dialogue stack, and completion/cancellation
+pops only the active top before resuming the flow underneath.
+
+`MAVEN_DIALOGUE_NO_SKIP=1 go test -race ./cmd/mavend -run
+'^TestDialogueTraces$' -count=1` passes all 22 traces. The complete forced
+`cmd/mavend` race suite passes in 208.031s. The integrated race command over
+`cmd/mavend`, `internal/dialogue`, and all `internal/router` packages also
+passes (162.310s for mavend; every package green). Focused structural
+possession, repair-pointer, nested-stack, and repaired-clarify tests pass under
+the race detector.
+
+### ONNX test/runtime lifecycle
+
+V-716 found that each embedder constructor tried to initialize ONNX Runtime,
+while `Close` destroyed only its session. In one package process the first
+model-aware test ran and later tests converted “already initialized” into a
+green skip. The router now owns the process-global environment through
+reference-counted leases held by each embedder and routing-head session; the
+last owned lease performs cleanup, and close is idempotent.
+
+The router and mavend test packages hold a lease across their model gates.
+`make eval-router` additionally requires proof that both named aggregate gates
+actually executed. In one process the classifier baseline scored 72/96 and the
+routing heads 93/96; destination was 11/33 and 25/33 respectively, and ecosystem
+reach remained 28/30. The lifecycle reacquire test, focused race suite, full
+aggregate command, and portable no-runtime packages all pass. Measurement:
+`docs/evals/2026-08-13-onnx-runtime-lifecycle.md`.
+
+### Clarification exhaustion is fail-closed
+
+V-717 closes the terminal-policy hole found during the V-573 audit. A request
+with two required gaps could spend its only question on the first, fill that
+slot, and then reach `applyAction` with the second still absent. The attempt cap
+was accidentally acting as permission to execute a partial action.
+
+The resolver now rebuilds the pending action and re-runs the canonical
+`missingFor` schema after every filled gap. One remaining gap produces exactly
+one next question only while the shared `PendingAction.CanAsk` budget permits
+it. Exhaustion visibly gives up, removes only the active stack level, and makes
+no write or action. `finishRebuilt` repeats the same invariant at the execution
+boundary. Reminder time answers remain separate from the clean payload but are
+included in the schema decision used for validation.
+
+The original `TestClarifySecondGapRespectsTheAttemptCap` now asserts the exact
+give-up and zero reminders. New tests cover direct boundary refusal and a
+two-level stack where exhausting the top appends the surviving lower question
+to the same reply. The focused V-717 race cases pass in 4.529s; every clarify
+case plus all 22 forced dialogue traces pass under the race detector in
+26.202s; `internal/dialogue` passes under race in 2.293s. Routing contract:
+`docs/routing.md` section “Required slots and attempt exhaustion”.
+
+### A suppressed nudge is identified before it is phrased
+
+V-687 closes the phrase-before-dedupe hole in the digestion worker. The dedupe
+was reported by `EnqueueDigestEntry`, which runs after `PhraseNudge` has already
+been paid, and the `else if deduped { continue }` meant to skip the cost was the
+last statement in the loop body. Every tick that kept suppressing the same rule
+spent the resident model again, against the cache claim in the comment above it.
+
+The fix gives a rule a durable semantic identity instead of hashing its prose. A
+rule eligible for the digest declares `DigestIdentity`, a function of state
+beside its predicate; `loop.DigestCandidateFingerprint` frames the rule name and
+severity around it so two rules cannot alias on a shared fact. `BreakRule`
+anchors on the last completed break rather than on `desk_active`, which is
+freshness evidence the poller refreshes without the unmet need changing. A rule
+with no declared identity does not enter the digest, because inventing a generic
+state hash would either change every tick or ignore an input the rule reads.
+
+`tick_digest.go` now looks up `LiveDigestEntry` by rule and fingerprint before
+phrasing. Migration #26 adds `candidate_fingerprint` with a partial unique index
+over live pending rows; `EnqueueDigestEntry` expires a matching stale row and
+inserts inside one transaction, so sweep order is not part of correctness and a
+second caller cannot race the pre-phrase read into a duplicate. Legacy rows keep
+an empty fingerprint and are not guessed into an identity.
+
+Six tests cover the contract: one phrase call across three suppressed ticks,
+zero after a daemon restart, and two when the meaning changes, when the entry
+expires, and when it has been drained. `./cmd/mavend/ -run TestSuppressedCareDigest`
+passes under race in 4.626s, the digest store and loop cases in 4.123s and
+1.046s, and the three full packages in 264.076s, 64.496s and 4.280s. The caveat
+`docs/caveats/workers.md#nudges` and the `SA4006` baseline entry are deleted.
+
+## 2026-08-15 — authoritative-state continuation
+
+The continuation began by treating the checked-out tree and external task state
+as authoritative. `master` was clean, identical to `origin/master`, and already
+contained the V-717 and V-687 branch merges. Their interrupted worker messages
+were therefore not used as evidence of missing work.
+
+### Live reminder catch-up closes V-570 and V-715
+
+The rebuilt stack loaded the resident Qwen model, multilingual ONNX embedder,
+and routing heads. On its first eligible tick it phrased the three overdue
+reminders once as one catch-up message. Disabled ntfy left one durable failed
+attempt for delivery group `reminder #83`; ordered fallback then left exactly
+one successful Telegram attempt for the same group. All originals became
+`fired`. Four later ticks produced no second phrase, send, pending attempt, or
+unknown attempt. `/`, `/reminders`, and `/notifications` each returned HTTP 200
+with a server-generated request ID. This supplies the live evidence that was
+still missing in the 2026-08-13 entry; V-715 and the stale-open V-570 are closed.
+
+The first HTTP repro command also exposed a zsh test-harness trap: `path` is a
+special array tied to `PATH`, so using it as a loop variable removed command
+lookup inside the loop. The corrected probe used `probe_path` and `wget
+--no-proxy`; the deployed web process had not crashed.
+
+### Stale-open task reconciliation
+
+The open Vikunja list was read with `done: false` and compared with the current
+tree before choosing work. V-397 already described itself as done and merged;
+V-557 is present as `ea0eb16` plus the forced missing-slot dialogue contract;
+V-570 is covered by the live catch-up proof above. Those three records were
+closed rather than reimplemented. V-651 remains open: its nil-sink and reminder
+spin halves landed with V-715, but the first failed severity-4 Telegram send is
+still not represented in the repeat-until-ack stream.
+
+### Stable hash-floor performance evidence [V-718]
+
+`TestPersonalBoundaryHashFloorLatency` coupled correctness to ambient machine
+load while running a numeric training loop under race and coverage
+instrumentation. It is now a deterministic fit-and-score test that also proves
+the 1024-dimensional head was built. Elapsed time remains observable through
+`BenchmarkPersonalBoundaryHashFloorFitAndScore`, where three one-iteration runs
+on this host measured 75.1 ms, 76.8 ms and 81.4 ms without making those host
+figures a CI pass condition.
+
+The exact race-plus-coverage focused test passed in 9.445s. `make test` then
+passed on its first run: formatting, vet, CW2 configuration tests, and every
+internal and command package under race plus coverage; `cmd/mavend` completed
+in 205.712s. This closes V-718 without raising a brittle timeout.
+
+### Delegation availability
+
+All three available subagent slots were filled: clarification exhaustion,
+durable nudge identity, and a read-only live deployment probe. The first two
+left complete merges on `master`; all three later reported the same shared
+Codex usage limit, with capacity unavailable until 2026-08-20. Work continues
+serially. The temporary constraint and revisit trigger are recorded at
+`docs/caveats/workers.md#agent-quota` under the V-714 completion umbrella.

He names a monitor, then asks four questions that all say \"он\" and never name it again.\n\nThis scenario exists because the shape had nowhere to fail. The routing fixture scores one utterance at a time, so a conversation that breaks on its second turn cannot lose a point there, and V-44 step 2 could only be verified by hand. That is item 3 of V-542.\n\nFour of the five replies below are WRONG, and the assertions pin them anyway. Read them as the recorded defect rather than the contract: she has the last four turns in front of her and never once names the thing he is asking about. Every wrong assertion is marked in its step note with what it must become. When V-542 lands, those flip and the ones marked correct do not move.\n\nWhat the four assert is that the reply LACKS \"монитор\". Absence is the defect itself: she is answering a question about a thing she wrote down two minutes ago and cannot name it. It also survives the fallback picker, which matters on the three query turns — they refuse from internal/phraser/fallbacks_ru_v1.json, four variants deep, and the same scenario returned \"тут я пас.\" one run and \"не знаю, честно.\" the next, so a string assertion there would pin the picker rather than the daemon.\n\nTurn 4 asserts its text as well, because that turn goes through the chat path and the chat path is now scriptable. scriptedPhraser in simulator_test.go answers PhraseChat from the same script entries the router reads (V-542 item 4); before it, the simulator wired phraser.NewStub() and no scenario could say what she SAYS on a chat turn at all.\n\nThe routes are scripted exactly as the box produced them, because the failure is not the model's. Turn 1 went to fact despite \"давай поболтаем\", every question after it went to query, and turn 4 went to chat. A scripted route is what lets this scenario pin the daemon's half without a llama-server in the loop.",

He names a monitor once, then refers to it by pronoun or ellipsis for four turns.\n\nThe router decisions stay exactly as the box produced them: fact, query, query, chat, query. That is intentional. Routing sees one utterance; dialogue continuity owns what earlier turns make it mean. A grounded fact inside an explicit conversational opener is still stored, while its exact utterance also enters the transcript. Anaphoric queries are answered through chat with that transcript instead of walking note and world sources without their referent.\n\nEvery scripted chat answer below is conditional on history containing the original monitor turn. A canned reply therefore cannot make this scenario pass if session capture, cross-intent merge, history ordering or PhraseChat wiring loses the referent. The visible assertions require the answer to name the monitor, and the final tick remains the not-a-nag control.",
