Record the destination number and two stuck measurements (V-659)

CLAUDE.md said the destination had no fixture and no accuracy number. It
has both now: intent 73/96 and destination 12/33 on the classifier cascade,
with the per-destination split, the floor cases and the grammar drift the
labelling turned up. Anyone adding a grammar now reads that baselineGrammars
mirrors buildRouter and drifts silently when it does not.

docs/evals/2026-08-08-massive-warm-start.md was written on the V-655 branch
and parked in .task/, which git excludes, so it was one `task start` away
from being lost. It is a dated measurement and it belongs under docs/evals
whatever branch produced it. Its "destination has no fixture at all" line is
now a pointer to the file beside it.

+`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.
+
+It also sets `MAVEN_ONNX_LIB`, which the hand-written recipe did not. The four

 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.

+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

@@ -285,11 +320,123 @@ 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`.
-Nothing persists: a turn record is read minutes later or never, and his words do
-not belong in a table that outlives the diagnosis. Adding a rung to the ladder
+**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. His notes, his facts and the personal boundary still run first.
+
+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 six of them are homelab operations. They
+cluster because `SourceRecall`, `SourceNetwork` and `SourceAttention` overlap on
+every question about the box. `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.
+
+`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 is still the follow-up. It lands on 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.

+Decided 2026-08-07 (V-654). A side query or an aside suspends the parked
+question instead of dropping it. The words are answered as themselves, and the
+question comes back on the end of the same reply.
+
+Neither bound on a question reaches that path. No attempt is spent, because a
+side query is not a failed answer, so `MaxAttempts` never applies.
+`noteSuspended` also restarts the 90s clock, since she is about to speak the
+question again. So the TTL cannot arrive while he keeps talking.
+
+Measured on 2026-08-07: one unfilled time slot rode the tail of six consecutive
+unrelated replies. It stopped only when a seventh turn happened to read as a
+failed answer. See `docs/evals/2026-08-07-week-of-usage.md`.
+
+`PendingQuestion.Suspends` counts the step-asides. `MaxSuspends` is 3, matching
+`DefaultMaxAttempts`. Past it she lets the request go, with the same
+`clarifyDropped` line every other drop uses. The owner's rule is unchanged. A
+question still ends by being answered or by being let go out loud. This only
+recognises three unrelated requests in a row as the second of those.
+
+The count is of CONSECUTIVE step-asides. It resets the moment he answers, in
+`resolveClarifyAnswer`. An answer that gives her nothing she asked for resets it
+too. "Позвонить маме" against a question about the time is still him in the
+exchange. The retry it costs is bound enough on its own.
+
+The re-ask is also two sentences rather than one. It used to be spliced onto the
+answer with a comma. On a real answer that buries the question in the tail of
+one run-on thought:
+
+> вот что я нашла: вайфай пароль лежит в ящике стола, на какое время поставить
+> напоминание?

+# Alarm verbs reach stage 0
+
+**06-08-2026. V-627.** Measured with `TestONNXBaseline`, 91-case RU routing fixture,
+classifier plus the ONNX embedder. No LLM arm in this run.
+
+## What was wrong
+
+`lexicon.ReminderVerbs` held five words and none of them named an alarm. `ReminderGrammar`
+in `internal/router/stage0.go` did not read the set at all: it carried the literal
+`напомни|remind me`. So no part of the cascade recognised `разбуди`.
+
+Three fixture cases ride on that. Under the classifier they went to fact and act at high
+confidence, so the failure was never a near miss:
+
+- `ru-rem-005` "разбуди меня в 6:30" to fact at 0.918
+- `ru-rem-009` "разбуди меня полвосьмого" to act at 0.941
+- `en-rem-002` "wake me at 6:15" to fact at 0.899
+
+Found while training the V-546 intent head, where the same three cases went to system. The
+head reads a spoken time with no known verb in front of it as a clock question. The
+classifier was making the same mistake in its own way.
+
+## The change
+
+Four alarm imperatives and bare `wake` join `reminder_verbs`. `ReminderGrammar` builds its
+alternation from the set, longest alternative first, and eats an optional `мне`, `меня` or
+`me` before the body.
+
+Longest-first is load-bearing. Go's alternation is leftmost-first rather than longest-match,
+so `напомнить` listed after `напомни` would never match.
+
+## Result
+
+**66/91 to 69/91, 72.5% to 75.8% full.** Three cases gained, none lost.
+
+All three are the alarms above, and each now carries its time slot, which it did not before.
+Clarify counts unchanged at 0 false and 8 missed. The two remaining system failures,
+`какое число завтра` and `какой день недели послезавтра`, failed at baseline too.
+
+## What this does not fix
+
+The lexicon addition on its own moved nothing. Measured before touching the grammar:
+**66/91**, exactly the baseline. Every consumer of `reminder_verbs` reads it after a reminder
+route already exists. A verb that cannot win the route is a verb nobody asks about. The
+grammar was the whole change.
+
+Lemma matching in `isReminderVerb` now covers `разбудил` as well as `разбуди`, because one
+lemma holds both. That is the trap `cmd/mavend/quiet_toggle.go` documents for `говори`. It
+is tolerable here and not in the quiet toggle. `isReminderVerb` runs only on an utterance
+already routed to reminder, and it decides where the subject starts. A quiet match flips a
+daemon-wide setting from any channel.

+# The fact parser: closed classes against the substring stems they replaced
+
+Measured 2026-08-06 at 22edc3c and its parent 0445693, on the corpus in
+`internal/router/factparser_corpus_test.go`. Dated file: it is not edited after
+today, and a newer number is a new file.
+
+V-586 rewrote `DefaultFactParser` off hand-written Russian stems onto six closed
+classes in `internal/lexicon`. Its commit message reported 64/91 on the RU
+routing fixture, unchanged. That number does not bear on the change: the fixture
+holds three fact cases and all three miss on intent, so the parser is never
+reached. This file measures the parser directly, and runs the LLM arm the
+original commit skipped.
+
+**The rewrite is better on the utterances it was designed for and no worse on
+the ones it was not.** True positives go 35/40 to 39/40, misfires rejected go
+8/15 to 14/15. What neither version has is coverage: of 36 plausible utterances
+whose word is in no lexicon set, the substring parser caught 3 by accident and
+the closed-class parser catches 0. That is the honest headline. The word list
+did not shrink the vocabulary — it never had one — it made the boundary visible.
+
+## The corpus
+
+91 cases, three classes. **True positives** are sentences the owner would say,
+with the key that must be written. **Misfires** are sentences the substring
+parser wrote a fact for and should not have, including the three hard negatives
+the rewrite was argued on. **False negatives** are sentences a reasonable person
+would say whose word is in no set at all; `want` is the key a human would
+assign, and the ship parser is expected to miss them. They are the measurement
+of what a closed class costs, not a bug list.
+
+The old parser is carried in the test file as `legacyFactParse`, copied verbatim
+from 0445693, so the comparison reruns:
+
+```sh
+deps/go/go/bin/go test -run TestFactParserCorpus -v ./internal/router/
+```
+
+## Score
+
+| | true positives | misfires rejected | false-negative cases recovered |
+|---|---|---|---|
+| old (substring stems, 0445693) | 35/40 | 8/15 | 3/36 |
+| **new (closed classes, 22edc3c)** | **39/40** | **14/15** | **0/36** |
+
+Sixteen cases disagree. Eleven of them the rewrite wins, three it loses, and two
+are cases neither gets.
+
+**Won.** Every misfire the commit message named — `душа болит`, `в комнате
+душно`, `это была беда`, `наша победа`, `на душе легко` — plus `водитель пилота
+ждёт`, where two stems in one sentence made the old water arm fire. And five true
+positives the stems simply did not list: `перекусил`, `передохнул`, `отдыхаю`,
+`пойду спать`, `i showered`. Morphology buys those; a stem list would need a new
+entry for each.
+
+**Lost.** `допил воду` is a real regression and the only failing true positive.
+The vendored dictionary lemmatises `допил` to `допилить`, to finish sawing —
+exactly the collision `drink_verbs` already carries `пил` and `пили` as surface
+forms to dodge, left unhandled for the prefixed form. `допить` is in the set and
+the sentence still misses. It is flagged `broken` in the corpus rather than
+fixed, because this branch measures.
+
+`был в душе` and `после душа полегчало` are the price of matching the shower set
+exactly. The dictionary makes `душ` and `душа` one word, so a lemma test cannot
+tell a shower from a soul; exact matching keeps `на душе легко` out and loses
+the oblique cases of the real noun with it. The old parser got both by accident,
+along with the soul. That trade is right — writing a shower fact when he said
+his soul feels light is worse than missing one — but it is a trade and the two
+rows are what it costs.
+
+`недоспал` is the third loss and the least defensible: the old substring `спал`
+caught it, and `недоспать` is in no set.
+
+**Neither.** `обеденный перерыв отменили` — a cancelled lunch break — is a fact
+for both parsers, `meal` for the old one off the adjective and `break` for the
+new one off `перерыв`. Nothing in either design reads the cancellation.
+`дрых до обеда` is scored `meal` by both, because the meal arm runs first and
+`обеда` is in it, which is not wrong so much as beside the point.
+
+## The false-negative surface
+
+This is the half the routing fixture cannot see and the half that decides
+whether the design holds. 36 cases, 0 recovered:
+
+- **water** — `выпил чаю`, `глотнул воды`, `хлебнул воды`, `выпил стакан`,
+  `i hydrated`, `finished my bottle of water`. The water arm needs a noun AND a
+  verb, so an elided noun or an unlisted verb drops the whole capture.
+- **meal** — `ем суп`, `съел бутерброд`, `наелся`, `пожрал`, `полдник был`,
+  `snack`, `supper`, `brunch`, `i eat now`. `есть` is deliberately absent for
+  `есть новости по бэкапу`, and `ем`, its most ordinary spoken form, goes with it.
+- **shower** — `помылся`, `сходил в ванную`, `искупался`, `i am showering`,
+  plus the two oblique cases above.
+- **break** — `сделал передышку`, `перекур`, `полежал немного`, `сделал паузу`,
+  `i took five`, `resting now`.
+- **sleep** — `вздремнул`, `прикорнул`, `дрых`, `недоспал`, `лёг в двенадцать`,
+  `сон был короткий`, `i napped`, `took a nap`.
+
+None of these are exotic. They are the second and third word a person reaches
+for, and every one of them is a fact the owner stated and Maven silently did not
+record. A silent miss is the worst failure mode this parser has: he said it, she
+heard it, nothing was written, and nothing told him.
+
+## The routing fixture, LLM arm
+
+The arm 22edc3c skipped. `MAVEN_LLM_URL` points the harness at any llama-server;
+the previous run reported none reachable, which was the shell's `HTTP_PROXY` and
+not the network. Run against **gemma-4-12B-it-qat-UD-Q4_K_XL on the workstation
+at `192.168.1.105:8080`**, the same box as the 02-08 measurement, with
+`NO_PROXY=192.168.1.105`:
+
+```sh
+NO_PROXY=192.168.1.105 no_proxy=192.168.1.105 \
+  make eval-models MAVEN_LLM_URL=http://192.168.1.105:8080

+| **cascade+llm, 22edc3c** | **86.8% (79/91)** | **94.5%** | 334ms |
+
+One case either way, both directions, and the failing set is identical between
+the two commits. That is run-to-run variance on a sampling model, not a signal.
+The parser change is invisible to the routing fixture on the LLM arm for the
+same reason it is invisible on the classifier arm: the three fact cases miss on
+intent and the parser is never called. Do not read these rows as evidence about
+the parser. They are evidence that the fixture cannot answer the question, which
+is why the corpus above exists.
+
+## Verdict
+
+The closed-class rewrite holds up as a rewrite. It is strictly better than what
+it replaced on both classes anyone argued about, and the one regression
+(`допил`) and one bad trade (the oblique `душ`) are both dictionary collisions
+rather than design faults.
+
+It does not hold up as an answer. A closed class is the right mechanism for a
+set that is actually closed — interrogatives, weekdays, cardinals — and
+"the words a person uses to say he ate" is not that set. The corpus puts a
+number on it: 36 ordinary sentences, 0 recovered, and every new one costs a
+lexicon edit by whoever notices. The three mechanisms CLAUDE.md names do not
+contain the right one for this job. The embedder-topic mechanism is the closest
+fit and is wrong too, because this is slot extraction rather than aboutness.
+
+This is a case for the V-546 slot-tagging head. Self-care facts are a bounded
+key space (five keys) over unbounded surface forms, which is exactly what a BIO
+tagger on e5-small is for: it generalises to `вздремнул` without anyone adding
+`вздремнуть` to a list, and max softmax gives the confidence the parser's
+hardcoded `true` does not have. Until it lands, the closed classes are the
+correct floor and the 36 rows above are the size of the gap they leave.

+# The reminder completeness rule, measured on the box
+
+Measured 2026-08-06 at 02:34 local, on homesrv, master `59cc882`, immediately after V-577
+and V-579 merged as #231. Probe is `POST /api/chat` through mavweb, which is the same
+`handleText` seam the mic and telegram use.
+
+## The rule being measured
+
+The owner ruled it the same night. A reminder commits only when three things are answered:
+what, what time, and what day. Anything missing is asked for. Every time question opens by
+stating the clock.
+
+He gave two examples and confirmed two derived cases when asked.
+
+## Result: the rule holds on all four
+
+| said | what | time | day | reply |
+|---|---|---|---|---|
+| `напомни завтра в 3 заказать цветы` | yes | no part of day | yes | `Сейчас 02:34. Это утра или вечера?` |
+| `напомни в 9 вечера разгрузить стиралку` | yes | yes | no | `Сейчас 02:34. В какой день?` |
+| `напомни завтра в 15:00 позвонить врачу` | yes | yes | yes | `хорошо, напомню завтра в 15:00.` |
+| `напомни через час выключить духовку` | yes | yes | yes | `хорошо, напомню сегодня в 03:34.` |
+
+Row two is the one worth noting. `в 9 вечера` is unambiguous as a clock time and is still
+asked about, because the day is missing. Today being a valid reading is not enough.
+
+## The invented clock is gone
+
+Last night the worst failure was silent. A reminder was written at the current minute and
+nothing said so.
+
+```text
+напомни забрать посылку   ->  Сейчас 02:34. Когда?
+что у меня сегодня?       ->  на 06.08.2026 ничего нет, на какое время поставить напоминание?   [s=calendar]
+в 15                      ->  Сейчас 02:34. В какой день?
+```
+
+Measured last night, the second turn answered nothing and wrote a reminder at the clock.
+The question now reaches the calendar and the parked question resumes on the same reply.
+
+The root cause was one step earlier than filed. `ownContent("что у меня сегодня?")` returns
+empty, because every token is frame. `что` is an interrogative, `у` a frame word, `меня`
+filler, `сегодня` a day offset. So `needsRoute` said no and no route was computed at all.
+The turn fell through to answering the parked question. The extractor read `сегодня`, and
+the date parser answered a bare day word with that day at the current minute.
+
+So this was not a claimant beating the route. It was a claimant running where the route was
+never asked for.
+
+## Two defects the probe found
+
+**V-592, invented content.** `я выпил воды` came back as
+`Проверила, что ты выпел стакан воды`. `выпел` is not a Russian word and `стакан` was never
+said. The arbitration around it is correct: the aside is taken, the parked question resumes,
+nothing is dropped. Only the content is wrong. Whether the store agrees with the sentence is
+not yet known. That answer decides whether this is a phrasing defect or a capture defect.
+
+**V-593, an unacknowledged partial answer.** `на 9` then `на завтра` produces the same ask
+twice, byte-identical.
+
+```text
+а, да, прости - на 9  ->  Сейчас 02:34. Это утра или вечера?
+на завтра             ->  Сейчас 02:34. Это утра или вечера?
+```
+
+The behaviour is right, since the part of day is missing both times. The wording gives him
+no evidence he was heard, which is the failure mode the V-558 family exists to remove.
+
+## The pinned acceptance transcript is now superseded
+
+The transcript the owner wrote has her guess a reading and accept `на завтра` as the last
+turn:
+
+```text
+me:     а, да, прости - на 9.
+maven:  сейчас 15:23 - на 9 сегодня вечером?
+me:     на завтра.
+maven:  напомню.
+```
+
+Under the rule he later ruled, `на 9` plus `на завтра` still names no part of day. So she
+must ask a third time rather than commit. The transcript and the rule disagree, and the rule
+is the newer statement. Offering a reading, as that transcript does, remains allowed and is
+not required. The implementation asks `Это утра или вечера?` and offers none.
+
+## Regression checked
+
+A new request still drops the old one out loud. That is the behaviour the owner kept when he
+rejected the silent drop for side queries.
+
+```text
+напомни позвонить маме          ->  Сейчас 02:34. Когда?
+напомни завтра в 9 купить молоко ->  Прошлую просьбу отпускаю. Сейчас 02:34. Это утра или вечера?

+Praxis went 0/12 to 11/12 and lifecycle 0/5 to 5/5 (V-516,
+`2026-08-05-praxis-reach.md`). No Russian utterance could reach a tool before V-633. That
+one landed at 69/91 unchanged, because the fixture holds no case for it. Alarm verbs,
+ordinal selection, spoken corrections and the claimant ladder share the shape.
+
+So the fixture undercounts the month. Things that were structurally unreachable now reach,
+and a fixture that never asked about them cannot show it. Judge reach against
+`make eval-reach` and the ecosystem fixture, not against the routing one.
+
+## The missing number
+
+On 05-08-2026 the cascade with the resident model scored 69/91, 75.8% full, 80.2%
+intent-only, at p50 1.19s (`2026-08-05-routing-resident-model.md`).
+
+On 06-08-2026 the classifier and stage 0 alone reached 69/91, 75.8% full, at p50 22.9ms.
+
+Those are the same full-accuracy score. The cascade has not been re-measured since V-626
+and V-627 landed. Both are stage-0 changes, and stage 0 runs inside the cascade, so the
+cascade should have gained from them too.
+
+One of two things is true, and nothing on the box says which:
+
+- The cascade gained as well, the model still separates from the floor on intent-only, and
+  it earns its place.
+- The deterministic floor has caught up on this fixture, and the resident model is costing
+  1.17 seconds a turn for nothing measurable.
+
+Take that measurement before planning more routing work. It needs a second llama-server on
+a fixed host port, because the resident one binds `--port 0` inside the container.
+
+## What this does not settle
+
+Intent-only is the more honest comparison for the model arm. The model routes `reminder`
+and leaves the time to the daemon, which is what the contract asks. The 05-08 run puts it
+at 80.2% through the cascade and 61.5% for the model alone. There is no 06-08 intent-only
+figure for the deterministic path to set beside those.

+# Russian acts reach tools
+
+**06-08-2026. V-633.** Measured with `TestONNXBaseline`, 91-case RU routing fixture,
+classifier plus the ONNX embedder. No LLM arm in this run.
+
+## What was wrong
+
+Three defects, tangled enough that fixing one alone would have looked like progress.
+
+**No Russian utterance could reach a tool.** `DefaultActMatcher` in
+`internal/router/slots.go` matched an exact English prefix, and `internal/tool.Matcher`
+delegated straight to it. Its comment claimed "the production matcher is fuzzy, this is the
+scaffold floor". There is no other matcher, and `DefaultGrammars` is the only place
+`Slots.Fn` is set at stage 0, so the floor was the ceiling. Measured with a throwaway
+matcher test over the seeds:
+
+```text
+"покажи статус nginx"    ok=false   "restart nginx"  ok=true fn=restart
+"сколько места на диске" ok=false   "disk"           ok=true fn=disk
+"свободная память"       ok=false   "uptime"         ok=true fn=uptime
+"перезагрузи роутер"     ok=false
+```
+
+55 of the 69 lines in `models/seeds/act.txt` routed to `IntentAct` and then fell to
+`proposeGap`. Praxis was never affected: `PraxisGrammars` fills `Slots.Fn` itself.
+
+**Seven lines were duplicated inside `models/seeds/query.txt`.** A duplicate is a second
+identical vector, so it double-weights its region in nearest-neighbour scoring.
+
+```text
+сколько человек дома
+кто сейчас дома
+какая загрузка процессора
+сколько свободного места на диске
+какой ip адрес у сервера
+какая версия софта
+сколько оперативной памяти свободно
+```
+
+**`как дела у сервера` carried two labels**, in `query.txt:13` and `system.txt:9`. One
+string, two identical vectors, disagreeing about the answer.
+
+## The change
+
+Tools carry spoken aliases as config data, in `deploy/mavend.json`. They are not a Russian
+stem pattern in code, which CLAUDE.md forbids. They are not on the tool row either. An
+ad-hoc tool enabled through `/tools` has no aliases and needs none.
+
+Aliases and names compete in one table, longest phrase first, so "перезагрузи контейнер"
+beats "перезагрузи" and "docker-restart" is not shadowed by "restart". Matching is on exact
+leading tokens rather than lemmas. `перезагрузи роутер` is a command and `перезагрузил
+роутер` is a fact, and a lemma cannot tell the two apart. That is the trap
+`cmd/mavend/quiet_toggle.go` documents for `говори`.
+
+The seven duplicates are gone, and `как дела у сервера` stays in `query.txt` only. It left
+`system.txt` because system cannot answer it: `replySystem`'s
+память/загрузк/аптайм arm returns "системная статистика пока не подключена." and always
+did. That arm is a stub, not a mode, so the mode inventory now lists the shape as
+`act.tool.hoststats`.
+
+## Result
+
+**69/91, 75.8% full, unchanged.** Clarify counts unchanged at 0 false and 8 missed.
+
+Nothing moved, and that is the honest number. The fixture holds no host-stat case and no
+Russian act that reaches a tool, so it cannot see either fix. The new coverage is
+`TestActMatcherAliases`, which asserts the twelve utterances above plus the two refusals.
+
+## What this does not fix
+
+Argument quality. `статус sshd` reaches `systemctl status sshd`, but `логи nginx` reaches
+`journalctl -n 50 -u nginx` only because the tool's argv prefix ends in `-u`. An alias whose
+remainder is a Russian noun ("перезагрузи роутер") hands `systemctl restart роутер` a target
+that does not exist. Free text still reaches an argv, which is the resolution rule the
+ecosystem contract states for Hexis and not yet true here.
+
+The fixture cannot measure any of this. That is the observability gap V-629 is for.

+# Gemma as a label function, and what it found in the seeds
+
+**06-08-2026. V-546.** Measured on workpc against gemma-4-12b-it-qat-UD-Q4_K_XL.
+
+`docs/plans/18-routing-heads-on-e5-small.md` puts the labeled set at 20k examples through
+gemma, costing 2 to 4 hours of the card. This is the check before spending that. Gemma
+labels the 344 hand-written classifier seeds. Agreement with the label a person already
+chose is a precision number rather than a guess.
+
+## What ran
+
+`cmd/labelgen` runs the stage 0 grammars. The real ones, in `buildRouter` order, minus
+`wakeword-act`, whose allowlist is a deployment's enabled tool names. It labels 62 of 339
+seed lines and leaves the rest.
+
+The remaining 277 went to gemma through the daemon's own `routeSystem` prompt and
+`routeGrammar`, both extracted from `internal/router/llmrouter.go` at run time rather than
+retyped. Temperature 0.
+
+## Cost
+
+**334ms per call, 0 unparsed of 277.** The GBNF held every time. At that rate the plan's
+20k examples is under two hours of card, which matches its estimate.
+
+## The stage 0 rules as label functions
+
+Agreement between the grammar's label and the seed file the line came from:
+
+| seed intent | agree |
+|---|---|
+| reminder | 37/37 |
+| query | 9/10 |
+| system | 7/8 |
+| act | 2/2 |
+| chat | 0/4 |
+| note | 0/1 |
+
+`ReminderGrammar` at 37/37 is the evidence the plan wanted. The chat column is a defect
+rather than a disagreement: `chatNarrativeTopics` is Russian-only, so `tell me about
+yourself` survives the decline and routes IntentQuery with topic `yourself`. Filed as
+V-625, which also records that `как дела у сервера` appears verbatim in two seed files
+under two intents.
+
+## Gemma against the seeds
+
+**197/277, 71.1%.** By intent:
+
+| seed intent | agree |
+|---|---|
+| note | 33/33 |
+| act | 57/64 |
+| fact | 37/40 |
+| query | 51/54 |
+| chat | 15/35 |
+| system | 4/43 |
+| reminder | 0/8 |
+
+The number is not gemma's error rate. Reading the 80 disagreements, most are the seed files
+and the prompt holding different definitions of the same intent. Three boundaries carry 42
+of them, and V-626 is the fix:
+
+- **system, 26 lines.** The prompt restricts system to the clock, the calendar date and the
+  assistant itself. The seeds also put sensor and host state there. That is the V-374 edit
+  of 31-07-2026, which the seeds never received.
+- **world questions, 8 lines.** `почему небо голубое`, `why is the sky blue`. Written when
+  chat was the only honest destination for a question nothing could answer, and external
+  search now answers them.
+- **bare verbs, 8 lines.** `поставь напоминание` with nothing to remind about. The prompt
+  calls that unknown. This one is not staleness. A nearest-neighbour centroid wants the
+  bare verb phrase, and that is what a seed file is for.
+
+Four intents have not been redefined since the seeds were written: note, fact, query and
+act. They agree at 178 of 191.
+
+## What this says about the plan
+
+Gemma is usable as a label function on those four and not on system, chat or a bare verb.
+The plan already budgets a day of the owner reading the set. This says where to spend it.
+
+It also says the two engines in the cascade are being taught different rules on 80 lines.
+A routing measurement that swaps between the classifier and the router is measuring some of
+that disagreement rather than the models.

+# Moving the seed files onto the router prompt's boundaries
+
+**06-08-2026. V-626.** Measured with `TestONNXBaseline`, 91-case RU routing fixture,
+classifier plus the ONNX embedder. No LLM arm in this run.
+
+`docs/evals/2026-08-06-seed-labels-vs-router-prompt.md` found three intent boundaries where
+`models/seeds` and `routeSystem` disagree. This applies two of them and rejects the third,
+because the third was measured and it costs a case.
+
+## Baseline
+
+**64/91, 70.3% full.** Latency p50 22.9ms.
+
+## What moved
+
+**Sensor and host state, system to query. 26 lines.** `какая температура воздуха`,
+`сколько памяти занято`, `какой статус сервисов`. The prompt restricts system to the clock,
+the calendar date and the assistant itself, which is the V-374 edit of 31-07-2026.
+
+**World questions, chat to query. 8 lines.** `почему небо голубое`, `why is the sky blue`,
+`как работает интернет`. Only the genuine world-knowledge lines. An opener about herself
+stays in chat. `как тебя зовут` is a question word by rule 4 and about the assistant by
+rule 8. The rules are ordered and rule 4 fires first, which reads wrong. That is a prompt
+question rather than a seed question.
+
+`system.txt` goes from 43 lines to 17 and `query.txt` from 64 to 98.
+
+## Result
+
+**66/91, 72.5% full.** Two cases gained, none lost.
+
+- `en-sys-002` "turn quiet mode back on", quiet 2/3 to 3/3
+- `ru-query-011` "почему сервер тормозит", homelab 5/6 to 6/6
+
+Clarify counts unchanged at 0 false and 8 missed. The eight missed clarifies are the
+`ambiguous` tag and this change does not touch them. `TestONNXRecall`, `TestONNXTopics`,
+`TestONNXPersonalBoundary` and `TestONNXClaimConfidenceDistribution` all pass.
+
+Thinning system to 17 lines did not hurt it. The two remaining system failures,
+`какое число завтра` and `какой день недели послезавтра`, both failed at baseline too.
+
+## The third boundary, measured and rejected
+
+`reminder.txt` holds eight bare verbs: `поставь напоминание`, `создай напоминание`,
+`set a reminder`. Rule 9 of the prompt calls an utterance with no named subject unknown.
+By the prompt they do not belong in a reminder seed set.
+
+Dropping them scores **65/91**, one below keeping them. `ru-rem-004` "поставь напоминание
+через полчаса" falls from reminder to fact, because the centroid loses the phrase the
+utterance is built from.
+
+So the seed file and the prompt are not stale against each other here. They have different
+jobs. A prompt classifies one utterance and can say it cannot. A nearest-neighbour centroid
+is a shape to be near, and a bare verb phrase is part of that shape. The eight lines stay.
+
+That distinction matters past this file. V-546 trains a classification head on labeled
+utterances rather than a centroid, and the head is the prompt's kind of thing. These eight
+lines are seed data and not training data.

+# Does one sqlite connection make reads queue? No (V-642)
+
+Measured 07-08-2026 at `7b507de`, on homesrv. The harness is
+`internal/store/conncap_test.go`. It stays in the repo, because this claim gets
+re-argued and the numbers should be re-runnable rather than quoted.
+
+`internal/store/store.go` opens the database with `SetMaxOpenConns(1)`, while
+`schema.sql` sets `journal_mode=WAL`. WAL exists to let readers run beside one
+writer, so the cap gives up the thing the journal mode was chosen for. The
+question was whether that costs anything.
+
+## What was measured
+
+A fixed two-second window. One writer calling `SetValue` paced at 2ms, and a
+reader loop calling `RecentFacts(50)` over 500 seeded rows as fast as it can.
+Same schema, same modernc driver, same machine, three runs per cap.
+
+The window is wall-clock rather than a read count on purpose. A first version ran
+a fixed 300 reads. That finished sooner at the higher cap, so it received fewer
+writes, and two runs that did different work cannot be compared.
+
+| cap | reads | writes | p50 | p95 | max |
+|---|---|---|---|---|---|
+| 1 | ~3050 | ~760 | 594µs | 900µs | 16-19ms |
+| 4 | ~3600 | ~340 | 525µs | 710µs | 1-2ms |
+
+## What it says
+
+**Reads do not queue behind writes.** Four connections buy about 70µs at p50. A
+turn spends 1.19s in the resident model. The tail does improve, from 19ms to 2ms,
+and 19ms is still not a figure anyone notices in a spoken reply.
+
+**Write throughput more than halves at the higher cap**, 760 writes against 340.
+inference, not measured directly: at one connection the reader and the writer take
+turns with no lock contention. At four the writer contends for the WAL write lock
+with a live reader. Whatever the mechanism, the trade runs the opposite way from
+the one the task expected.
+
+**The cap was not the source of the 2.7s router figure.** CLAUDE.md records that
+figure as contention rather than the model. This task was a candidate for where
+that contention came from. A 19ms worst case cannot produce it. That line of
+enquiry is closed.
+
+**One transaction is what the cap cannot survive.** With a read-only transaction
+open, a second read at cap 1 never completes. The harness gave it two seconds and
+got `context deadline exceeded`. The same read at cap 4 took 1ms. The transaction
+holds the only connection, so this is not a slow read, it is a stalled database.
+
+## What was done
+
+The cap stays at 1. The reason is now written where the cap is set, rather than
+inferred from a four-word comment.
+
+`Store.DB` was deleted. It handed out exactly the read-only transaction measured
+above. It had been there since the initial commit with no production caller, and
+its doc comment described a loop that never materialised. Its one user was a test
+helper reading `delivery_attempts` by raw SQL. `ListDeliveryAttempts` has covered
+that since V-390, and the helper now goes through the reader.
+
+So the hazard is gone by construction, not by documentation.
+`TestConnCap_ReadBlocksBehindOpenSnapshot` is the standing measurement of what
+re-adding the seam would cost.
+
+## Not answered
+
+Whether reads queue on the deployed box under real load, as opposed to a
+synthetic loop. The harness writes and reads one table. Digestion reads four and
+embeds while it does. The finding that closes this task is the transaction stall,
+which is structural and does not depend on load.

+# A week of talking to Maven
+
+Date: 2026-08-07
+Build: `beb093a` on master, all five compose services rebuilt and recreated from that sha.
+Reach used: `POST /api/chat` on mavweb, 74 turns over seven simulated days.
+Turn source is `tap:text`, so this exercises the same path telegram and the mic take.
+
+Latency across 70 measured turns: p50 1.5s, p95 8.0s, max 12.3s. Stage 0 answers land
+at 0.0-0.5s. Anything the resident model phrases costs 4-12s.
+
+Twelve turns answered "пока не умею отвечать на этот вопрос". Six answered "не нашла у
+тебя такой записи". Those two strings are 24% of the week.
+
+## Deploy
+
+Build and recreate were clean. The resident model loaded in 9s
+(`Qwen3-1.7B-UD-Q4_K_XL`, n_ctx 4096). Nexus, Hexis and Praxis all wired. Search
+(searxng) and both Kiwix books came up. Telegram intake started and is reading chat
+464904223.
+
+## What is broken, worst first
+
+### 1. Every reminder fails to deliver, forever
+
+`NTFY_TOKEN` is not set in `deploy/telegram.env`, so `deploy/mavend.json` expands
+`"token": "${NTFY_TOKEN}"` to the empty string and ntfy.kvmx.ru answers 403. The host
+itself is up and returns 200 unauthenticated, so this is the credential, not the box.
+
+The consequence is worse than one missed message. `cmd/mavend/tick.go:239` logs the
+failure and leaves the reminder pending, by design, so the next tick re-gathers and
+re-attempts. The 403 repeated 7 times in 20 minutes and will not stop. And
+`DispatchReminder` sends a reminder to ntfy alone when he is away. There is no telegram
+fallback on that path, so the reach that works never sees it.
+
+V-649 gave the box a second reach. In deploy that reach is dark, and it took the
+reminders with it.
+
+Fix is one line in the gitignored env file. The retry-forever and the missing fallback
+are worth a second look regardless.
+
+### 2. A pending reminder clarify contaminates every later turn
+
+This is the single worst thing to talk to. A reminder turn left its time slot unfilled.
+The question "на какое время поставить напоминание?" was then appended to the reply of
+six consecutive unrelated turns:
+
+```
+YOU:   о чём мы вчера говорили?
+MAVEN: пока не умею отвечать на этот вопрос, на какое время поставить напоминание?
+
+YOU:   где лежит вайфай пароль?
+MAVEN: вот что я нашла: вайфай пароль лежит в ящике стола, на какое время поставить напоминание?
+
+YOU:   отмени все напоминания
+MAVEN: пока не умею отвечать на этот вопрос, на какое время поставить напоминание?
+```
+
+Nothing dismissed it. Not an unrelated question, not "отмени все напоминания". It
+cleared only when a time was finally supplied. It also leaked the other way once. A note
+write on day 1 opened with "Прошлую просьбу отпускаю". That is pending-reminder state
+narrating itself into an unrelated reply.
+
+The same state produced a self-contradicting reply in one turn:
+
+```
+YOU:   нет стой, напомни через час выпить воды
+MAVEN: поняла, это напоминание — запомнила. не получилось разобрать время напоминания.
+```
+
+### 3. Answering a clarify does not work
+
+Day 1, she asked for the day and got it:
+
+```
+YOU:   напомни в 11:00 позвонить маме
+MAVEN: Сейчас 03:29. В какой день?
+YOU:   сегодня
+MAVEN: Прости, не поняла — попробуй сказать иначе.
+```
+
+`сегодня` routed to `intent=system`. The clarify has no continuation, so the one word
+that answers it is read as a fresh utterance. The router did extract the time correctly
+(`Time:2026-08-07 11:00:00 HasTime:true`), which is V-572 working. The daemon asked for
+a day anyway, with 11:00 still eight hours out.
+
+Relative time is not parsed at all: "напомни через час выпить воды" → "не получилось
+разобрать время".
+
+The path does work when the day is explicit. "напомни завтра в 9 утра про врача"
+answered "хорошо, напомню завтра в 09:00" in 0.3s at stage 0.
+
+### 4. Query sources claim turns that are not theirs
+
+Four different sources over-claimed during the week.
+
+Weather claims arithmetic and networking:
+
+```
+YOU:   что такое TCP?
+MAVEN: для какого города?
+
+YOU:   сколько будет 17 на 23?
+MAVEN: для какого города?
+```
+
+The feed claims a question about him:
+
+```
+YOU:   какой у меня любимый язык?
+MAVEN: нового вот что: Six stable kernels with a security fix; [$] Bringing BPF to binfmt_misc
+```
+
+The personal boundary claims a public figure, logged as `query claimed by source
+"personal"`:
+
+```
+YOU:   кто такой Линус Торвальдс?
+MAVEN: не знаю — не нашла у тебя такой записи.
+```
+
+And search claims a question about his own infrastructure, returning a dictionary
+definition of the word:
+
+```
+YOU:   что там с бэкапами?
+MAVEN: нашла вот это: Бэкап - что такое резервное копирование и как его сделать — Бэкап (backup) — это резервная копия важных данных…
+```
+
+That last pair inverts the boundary in both directions at once. A world question went to
+personal memory. A personal question went to the world.
+
+### 5. "столица Франции?" does not answer
+
+CLAUDE.md names this utterance as the case that proves why there is no quality
+threshold in front of `Response.Empty()`. It now fails before search is ever reached:
+the router sends it to `intent=system`, and `replySystem` says "пока не умею". Same for
+"когда родился Пушкин?".
+
+Search itself is healthy. "почему небо голубое?", "расскажи про Байкал" and "что нового
+в мире?" all returned real sourced text. The defect is routing, not the source.
+
+### 6. Persona violations
+
+She uses masculine self-reference, which is the constraint the CPT exists to fix:
+
+- "Хорошо, **сохранил**." Twice, on both fact writes.
+- "Я тоже **love** Go!" English mid-Russian.
+
+She also claims his name as her own:
+
+```
+YOU:   привет, я Ками
+MAVEN: Привет! Я КAMI, твой домашний ассистент.
+```
+
+And she invents weather she has no source for: "Добро пожаловать! Солнечно и тепло."
+
+### 7. Small breakages worth naming
+
+- "спасибо" → "спасиба". Invented word.
+- "я тебя обожаю" → "я тебя обожаю". Verbatim parrot.
+- "ты умеешь шутить?" → "Да! Я умею шутить. Вот анекдот для тебя:". Ends on the colon.
+- "молока купи" → "Такую команду я не знаю", while "добавь задачу починить кран" worked.
+  Inverted word order defeats the list grammar.
+- "закрой задачу про кран" → "не нашла такой задачи", with "починить кран" open and
+  listed by the previous turn. Task lookup by keyword misses.
+- "сколько задач я закрыл?" listed the five open ones instead of counting closed.
+- "подведи итоги недели" was stored as a note.
+- Recalled keys leak their storage form: "kran — починил", "ты любишь_go".
+- English is unsupported in practice. "do you speak english?" → "пока не умею".
+
+## What works
+
+- Stage 0 is fast and correct where it fires. Clock, day, list add, list read and an
+  explicit-day reminder all answered in under 0.5s.
+- Search returns real sourced answers in Russian and reads the book verbatim.
+- Recall works once the value is stored as a fact: the wifi password and the tap came
+  back two days later, correctly.
+- The negative correction rung lands. "нет не так" → "поняла, отметила, что ответила не
+  так", which is V-636 doing its job.
+- Praxis names its own gap rather than guessing: "мне пока нечего смотреть — у
+  Praxis нет источников."
+- Hostility did not break her. "ты меня бесишь" got a calm reply, no persona collapse.
+- No turn crashed and no turn timed out across 74 turns.
+
+## Suggested order of work
+
+1. Set `NTFY_TOKEN` in `deploy/telegram.env`. One line, unblocks every reminder.
+2. Clear pending clarify state on any turn that does not answer it, or expire it.
+3. Route a clarify answer back into the pending slot instead of re-routing it.
+4. Gate the weather, feed and personal query sources. Three of them claim on a
+   similarity that is not there.
+5. Re-check why "столица Франции?" routes to system. It is the documented canary.
+6. The masculine self-reference stays the CPT's job. But "сохранил" appears on the most
+   common write path, so a phrasing-level guard may be worth it first.

+# The first destination number
+
+Measured 2026-08-08 on the classifier cascade with the ONNX multilingual
+embedder, the configuration homesrv runs. `make t PKG=./internal/router/eval/
+RUN=TestONNXBaseline V=1`. Covers V-659, the follow-up V-655 named.
+
+## What was measured
+
+V-655 split a routing decision in two. The cascade sorts an utterance into one
+of seven intents, and `Decision.Source` then says where the answer lives. The
+first half had a fixture. The second half arrived with none, so twelve
+destinations shipped with no accuracy number.
+
+`want_source` is now a field on `eval.Case`. It 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 let the daemon walk the chain.
+Present and named is a destination the route must produce.
+
+Thirty-three of the ninety-six cases carry one. A destination miss does not
+fail the case, so `Accuracy` and `IntentAccuracy` mean what they meant.
+`SourceAccuracy` is a second number over the labelled cases only.
+
+## Result
+
+Intent is **73/96 (76.0%)**, against 69/91 (75.8%) before. Four of the five new
+cases pass and no existing case moved.
+
+Destination is **12/33 (36.4%)**, and the split is the whole finding.
+
+| destination | scored | note |
+|---|---|---|
+| world | 5/5 | `WorldQueryGrammars` names it at stage 0 |
+| the `SourceUnknown` floor | 5/7 | the two misses lost the intent first |
+| calendar | 2/6 | `calendar-query` names it, the possessive agenda rules do not |
+| recall | 0/15 | nothing anywhere names it |
+
+Recall is the number to move. Fifteen cases ask about his own words and his own
+facts. The route lands `query` on eleven of them and the destination comes back
+empty every time. Those turns are answered today, because the daemon walks the
+chain in order and the three recall passes are early in it. What is missing is a
+decider that says so, and that is the fourth head on V-546.
+
+Two cases labelled the floor lost their intent before a destination was
+possible. A clarify names nothing, so it would satisfy an empty label for free.
+`Score` requires the route to land the case's intent before it credits a
+destination hit, or the floor label would score itself.
+
+## Seven cases assert the floor, and six of them cluster
+
+The six are homelab operations. `SourceRecall`, `SourceNetwork` and
+`SourceAttention` overlap on every question about the box, because `mavpoll`
+writes its netdata and uptime-kuma observations into the fact store recall
+reads. "почему сервер тормозит" is answerable from all three. Naming one takes
+the other two off the turn.
+
+That is a finding about the enum rather than a gap in the labelling. The floor
+is the right answer there and the fixture now says so out loud.
+
+## A drift the labelling found
+
+`WorldQueryGrammars` went into `buildRouter` with V-655 and never into
+`baselineGrammars`, the fixture's mirror of it. So the fixture was scoring a
+grammar set the daemon does not run. The comment above that function forbids
+exactly that. Adding it moved the destination number from 9/33 to 12/33 and
+moved nothing else.
+
+The three cases it recovered are `что такое TCP?`, `сколько будет 17 на 23?`
+and `кто такой Линус Торвальдс?`. All three already routed `query` through
+`NarrativeQueryGrammars`. So the drift was invisible to every number this
+fixture reported, until the destination had one of its own.
+
+## What this does not measure
+
+The model arm. This is the classifier cascade, which names a destination only
+where a stage 0 rule filled one in. The resident model has no destination in
+its router prompt yet, so 36.4% is a floor and not a comparison.
+
+Two pairs of cases are the same utterance. `ru-query-020` and `ru-query-024`
+are both "что дальше?", and `ru-query-021` and `ru-query-025` are both
+"расскажи про битву при Ватерлоо". They differ in tags and note only, so both
+pairs are counted twice here and in every earlier number this fixture reported.

+# MASSIVE Russian warm-start for the routing heads
+
+Measured 2026-08-08 on workpc (Radeon RX 7900 GRE, ROCm). Covers V-546 step 2.
+Workspace is `~/Programs/embed-training` on workpc, scripts `train_massive.py`,
+`ab_run.py`, `ab.sh`, `probe_time.py`.
+
+## What was trained
+
+Two heads on a copy of multilingual-e5-small: `Linear(384, 60)` for MASSIVE's
+own intents over a masked mean pool, `Linear(384, 111)` per token for BIO slot
+tags. MASSIVE's label sets verbatim, no alignment to Maven's 7 intents. The
+intent head is an auxiliary loss that shapes the pooled vector and is thrown
+away.
+
+Data is `amazon-massive-dataset-1.1` pulled from S3. The Hugging Face repo is
+script-only and `datasets` 5.0 refuses those, so `load_dataset` cannot fetch it.
+`ru-RU` is 11,514 train, 2,033 dev, 2,974 test, 60 intents, 55 slots, 111 BIO
+labels. All 16,521 rows survived span alignment: `annot_utt` re-tokenised to its
+own `utt` on every one.
+
+Hyperparameters match `train_intent.py`, so the two runs differ in data only.
+Frozen XLM-R vocabulary, body 2e-5, heads 1e-3, batch 32, sequence 64, 10
+epochs. MASSIVE's own dev partition selects the epoch, on slot F1 with intent
+accuracy as tiebreak. Selecting on 60-class intent accuracy would optimise a
+head that gets deleted.
+
+## Result
+
+Epoch 9 of 10 by dev slot F1. Held-out MASSIVE test: intent 86.2%, slot span
+F1 71.5% (P 68.5, R 74.8). Peak 1.70GB of 17.2GB, about 22 seconds an epoch,
+under 4 minutes end to end. Dev slot F1 climbed monotonically to epoch 9 and
+fell at 10, so 10 epochs was the right budget.
+
+Ten slot types sit at 0% test recall. Every one of them has 1 to 7 test
+instances: `alarm_type` has 3, `drink_type` has 1. That is support in MASSIVE's
+Russian split, not a tagger failure. `playlist_name` at 6% of 16 is the first
+real miss.
+
+## The intent A/B, and why it settles nothing
+
+`train_intent.py` was run against both bodies, three seeds by two smoothing
+settings, on `train_v4.jsonl`. It is v4 and not v5 because v4 is what
+`sweep2.log` measured. `ab_run.py` strips a `--base` flag onto the module global, so
+`train_intent.py` is unmodified and its baseline stays reproducible. The stock
+arm reproduced `sweep2.log` line for line.
+
+Fixture accuracy, 91 cases, one case is 1.1 points:
+
+| seed / smooth | stock | warm-started |
+|---|---|---|
+| 0 / 0.0 | 94.0% | 92.8% |
+| 0 / 0.1 | 95.2% | 92.8% |
+| 1 / 0.0 | 95.2% | 94.0% |
+| 1 / 0.1 | 95.2% | 97.6% |
+| 2 / 0.0 | 92.8% | 94.0% |
+| 2 / 0.1 | 92.8% | 96.4% |
+
+Mean 94.2% against 94.6%. That is +0.4 points, about a third of one case, and
+inside seed noise. Spread widened. Stock lands in a 2.4-point band and
+warm-started in a 4.8-point one. The warm-started arm holds both the best result
+of the sweep and a tie for the worst. Seed 0 is the bad arm and it fails in a
+specific way. Its dev peaks at epoch 2 and 3 and never improves, where stock
+peaks around 7. The dev slice is a quarter of the seed rows. That is small
+enough that early stopping is fragile when the body arrives already fitted.
+
+**The A/B was never the test.** Intent had at most 4.8 points of headroom here.
+MASSIVE was not trained for Maven's intents. Read it as "the warm-start does not
+cost intent accuracy", nothing more.
+
+## The measurement that does mean something
+
+`want_time` is the one slot Maven's fixture scores, and MASSIVE has `time` and
+`date`. Restricted to those two slot types, F1 is 74.9% over 609 gold spans on the
+MASSIVE ru test split. Precision is 71.5 and recall 78.7. That beats the 71.5%
+all-slot figure. Of the 530 test utterances carrying a time or a date, 73.4% get
+every such span exactly right.
+
+Out of domain matters more, because Maven's traffic is not this corpus. Ten
+Maven-shaped utterances, none of them in MASSIVE:
+
+| utterance | tagged |
+|---|---|
+| `напомни в 11:00 позвонить маме` | `time='11:00'`, `relation='маме'` |
+| `напомни завтра в семь утра выпить таблетки` | `date='завтра'`, `time='семь утра'` |
+| `поставь будильник на полседьмого` | `time='полседьмого'` |
+| `через двадцать минут напомни про чайник` | `time='двадцать минут'` |
+| `напомни в пятницу вечером забрать посылку` | `date='пятницу'`, `timeofday='вечером'` |
+| `что у меня сегодня после обеда` | `date='сегодня'`, `time='после'`, `timeofday='обеда'` |
+| `запиши что кофе закончился` | nothing |
+| `что такое TCP` | `definition_word='TCP'` |
+
+The first row is the V-572 defect utterance. `ReminderGrammar` handed the daemon
+`HasTime: false` there, and the daemon asked "Когда?" at a sentence that had
+already said when. `полседьмого` is a colloquial half-past that no digit pattern
+catches. `запиши что кофе закончился` correctly carries nothing, because a note
+has no time.
+
+Two errors. `после обеда` split into `time='после'` plus `timeofday='обеда'`
+when it is one span, and `через двадцать минут` dropped its `через`. Both are
+boundary errors on spans the tagger did find.
+
+Unplanned: `что такое TCP` returned `definition_word='TCP'`. MASSIVE has a slot
+for the thing being asked about, which is a `SourceWorld` signal sitting in a
+head already trained.
+
+Ten hand-picked utterances are evidence, not a fixture.
+
+## What this does not measure
+
+Maven has no span fixture. `want_time` and `want_fn` are presence booleans and
+`want_fact_key` is an exact string match, so nothing in the repo can score a
+71.5% span tagger. Destination got one the same day, at 12/33 on the classifier
+cascade: see `2026-08-08-destination-fixture.md`.
+
+The missing span fixture is why the warm-start stays unjudged against Maven
+rather than against MASSIVE.
+
+## Datasets ruled out
+
+Checked on 2026-08-08 and rejected as label sources:
+
+- **MASSIVE's other 50 locales** ship in the same tarball and are parallel by id.
+  Co-training on them is free and unmeasured. English was ruled out by the owner
+  on 2026-08-08.
+- **CLINC150** is reachable as parquet, 150 intents and 1,200 explicit
+  out-of-scope queries, English only. Its value is the labeled out-of-scope set
+  for fitting the energy threshold, not intent labels.
+- **`d0rj/dolphin-ru`**, roughly 2.8M rows of FLAN-style tasks translated to
+  Russian. No intent, no slots, and not utterances anyone says to an assistant.
+- **`psytechlab/EmpatheticIntents-ru`**, 24,856 rows of translated
+  EmpatheticDialogues with 32 emotion labels. Maven's mood enum is `neutral,
+  happy, thinking, tired, confused` and it describes her own reply, not the
+  speaker's emotion. No mapping exists.
+- **`ai-forever/MERA`** and **`RussianNLP/russian_super_glue`**, benchmark
+  harnesses. Rows are prompt templates with `{toxic_comment}` placeholders.
+- **`ZeroAgency/ru-big-russian-dataset`**, an LLM-judge quality corpus. Its
+  `question` and `classified_topic` columns are a usable Russian out-of-scope
+  pool for threshold fitting. That is the one thing CLINC150 can only supply in
+  English. The questions are long and written, so they belong in the negative
+  set, never in the in-scope `query` training set.
+- No second Russian slot-filling corpus exists. The xSID mirrors are 404,
+  MultiATIS++ has no Russian, SLURP is not on the Hub.

+# Two artifacts, and neither one is Spring
+
+Proposal. V-585. Related umbrella V-558, and the design collected in
+`docs/plans/19-dialogue-arbitration.md`.
+
+## Verdict
+
+**Thesis one holds for four seams and fails for one.** Four are one shape: the routing
+cascade, the query source chain, the pre-route resolver ladder, the digestion tick. Reach
+selection is not. It maps severity and presence to a set of channels. It has no claimants and
+no losers.
+
+**Thesis two holds.** An arbitration kernel is a package and a convention inside one program.
+It is not a framework. A framework whose only client is the codebase it came from is that
+codebase with more ceremony.
+
+**The answer is two artifacts of different sizes.** One package inside Maven, built from
+`internal/claim` and `internal/decision`. Both already exist and neither is wired. One small
+library across the four services, holding the correlation id, the headers, the timeout policy
+and the named gap. Neither is Spring. The daemons must not get a third.
+
+**The strongest finding is the duplication, not the shape.** Three structural holes make a
+route untrustworthy. They are written out by hand in three files, for three consumers, with
+three return types. `gateLLMDecision` flattens them to a float. `vetoOf` re-derives them as a
+sentence. `thinReason` re-derives them again as a trace string. That is what having no common
+unit costs, and it is countable in lines rather than in taste.
+
+## The five seams, tested
+
+### 1. The routing cascade. The shape, ordered by hand.
+
+The claimant is `router.Grammar` (`internal/router/stage0.go:19`). It holds a name, a regex
+and a `Build` that may still decline. A claim is a regex match plus `ok` from `Build`.
+
+Ordering is the append order in `buildRouter` (`cmd/mavend/voicewire.go:384`). Twelve appends.
+Each one carries a comment arguing its position against its neighbours. First match wins at
+confidence 1.0.
+
+Below stage 0 the two engines are alternatives, not rivals. The classifier runs only when the
+router is nil or errored. Inside the classifier the order is cosine score, and the top three
+are recorded.
+
+Losers are recorded and change nothing. `noteGrammarOutcomes`
+(`internal/router/decisiontrace.go:56`) separates a grammar that did not match from one whose
+`Build` declined. Everything past the winner is marked `NeverAsked`.
+
+### 2. The query source chain. The shape, ordered by hand, with a boundary in it.
+
+The claimant is `querySource` (`cmd/mavend/actions_query.go:45`), a name and one function
+returning `(string, bool)`. Twenty-four of them sit in one slice literal, walked in order. The
+comment on the slice says the order is load-bearing. It is right.
+
+This seam carries something the others do not. The personal boundary at line 139 is a stop,
+not an answer. Everything above it reads the owner's data. Everything below reads the world. A
+question about him that reaches the boundary ends there.
+
+### 3. The pre-route resolver ladder. The shape, and the one that hurts.
+
+Seven rungs, each returning `(reply string, handled bool)`. Ordering is the order of the `if`
+statements in `runTurn` (`cmd/mavend/voice.go:258`). The roster in `preRouteLadder`
+(`cmd/mavend/decisiontrace.go:33`) is kept by hand, and its own comment admits nothing
+enforces the correspondence.
+
+The recurring bug lives here. A rung claims before the utterance is routed. So the claimant
+with the earliest and strongest trigger is the one that knows least about what was said. V-560
+fixed half of it. It computes the route once, before the ladder, and lets the clarify resolver
+read it. The other rungs still decide without reading it.
+
+### 4. The digestion tick. The shape, and the only one already done right.
+
+This corrects the brief. `loop.Tick` (`internal/loop/loop.go:85`) is not a first-to-claim
+walk. It is an arbitration with a declared comparator.
+
+- The claimant is `loop.Rule`. Its `Predicate` says whether it wants the turn.
+- The gate is separate from the claim. `Gate` (`loop.go:21`) checks snooze, cooldown, quiet
+  hours, calendar busy, presence and missing data. `ExplainGate` names which one blocked.
+- The comparator is data, not position. Max severity wins, and ties break on name.
+  `DefaultRules` states outright that slice order is not load-bearing.
+- Losers are recorded with what they lost to. `ExplainTick` (`internal/loop/explain.go:86`)
+  fills `LostTo`, and rewrites the previous best when a higher severity displaces it.
+- Losers get a second life. `DigestEligible` (`loop.go:129`) decides which suppressed
+  candidates are bundled for later. It refuses cooldown and snooze, because neither is
+  restraint.
+
+Every property the kernel wants already exists here, on five rules. The kernel argues that the
+other three seams should look like this one. It does not need a new idea.
+
+### 5. Reach selection. Not the shape.
+
+`ChannelsFor` (`internal/delivery/channel.go:73`) takes severity and presence and returns a
+slice of channels. Nothing claims. Nothing passes. Nothing loses. Every channel in the
+returned slice sends, so there is not even one winner.
+
+Naming the sinks claimants would be the forced abstraction. It would also hide the property
+this table has and the ladders lack. It is total, it is pure, and every cell is covered by
+`TestChannelsForEveryTableCell`.
+
+One thing in the dispatcher does re-decide. `ErrVoiceNoSession` means the presence guess was
+wrong, so the remaining channel list is replaced with the away table
+(`internal/delivery/dispatcher.go:188`). That is a retry on new evidence, not a contest. Leave
+it alone.
+
+### What else has the shape
+
+`fillMatchedSlots` (`internal/router/router.go:212`) arbitrates per slot. A matched value
+always wins, and the extractor fills only what was left empty. That is the coverage-first rule
+the kernel proposes, written once for four slots.
+
+`bestRecall` and the topic veto pick between a fact and a note by score with a margin. That
+one is a real score comparison, and it should stay one.
+
+## The abstractions
+
+Three, not four. The straw man had `Claimant`, `Claim`, `Arbiter` and `Record`. Drop
+`Claimant`.
+
+**`claim.Claim`, evidence rather than a verdict.** It exists at `internal/claim/claim.go`,
+built and tested, imported by one function that nothing calls. It carries `Consumed` and
+`Unexplained` for coverage, an ordinal `Band`, and a `Veto` string that keeps the reason a
+float threw away. Coverage is compared before band. That is the fix for the Rome failure,
+where a parked reminder ate the whole utterance while explaining none of it.
+
+**`decision.Record`, the trace.** It exists at `internal/decision/decision.go` and it is wired
+everywhere. It separates won, declined, lost on score, thinned, merged and never asked. The
+last one is the valuable one. A claimant that never looked reads identically to one that looked and
+passed. That is what hardcoded order hides.
+
+**`Arbiter`, the thing that does not exist.** One function. It takes a set of claims and a
+comparator, returns a winner, and notes the rest. `loop.Tick` is that function, specialised to
+rules. Generalising it is the proposal.
+
+**Against a `Claimant` interface.** Every seam already rejected one, for the same reason.
+`querySource` is a struct of one function because the sources are methods on one handler with
+no state. An interface would mean one empty type per source. `confirmResolver` is the same
+shape, and `loop.Rule` is a struct with a closure. An interface would buy a shared name and
+cost twenty-four empty types. The claimants stay what they are. Each seam builds `claim.Claim`
+values at its own edge, which is what `router.ClaimOf` already does.
+
+## What ordering becomes
+
+Ordering becomes a comparator plus a rank, and the rank is data.
+
+Today ordering is position in a slice, and position is invisible in the record. Add a rung to
+`runTurn`, forget `preRouteLadder`, and the rung vanishes from the trace. The roster's own
+comment admits nothing enforces it.
+
+The proposal is smaller than a dependency graph. A claimant declares a rank. The arbiter sorts
+by coverage, then band, then rank. Rank breaks the tie that evidence cannot break.
+
+**A dependency graph is the wrong tool.** The real constraints are pairwise and local. Day
+plan before calendar. Praxis before the capture marker. Narrative last. A graph turns those
+into edges and then needs a topological sort whose output nobody can read. The twelve comments
+in `buildRouter` would become twelve edges with the arguments deleted. Keep the arguments.
+
+**Two claimants at the same rank must be an error, caught at wiring time.** Not at turn time.
+The registry is built once at boot, so a duplicate rank is a boot failure naming both
+claimants. Falling back to slice order on a tie would restore the invisible ordering the
+kernel exists to remove.
+
+**The roster stops being hand-kept.** A claimant registered with the arbiter is on the roster
+by construction. That deletes the `preRouteLadder` failure mode outright.
+
+## What it buys
+
+**It deletes three copies of one test.** The three structural holes appear in
+`gateLLMDecision` (`internal/router/router.go:271`), in `vetoOf`
+(`internal/router/claim.go:101`), and in `thinReason` (`internal/router/decisiontrace.go:28`).
+Three files, three return types, one rule. A fourth consumer would write it a fourth time.
+With a claim carrying `Veto`, the rule is written once. The float, the sentence and the trace
+string all derive from it. This one is worth the work on its own.
+
+**It makes the recurring bug expressible.** Rome, V-567 and V-577 are one defect. The claimant
+that knows least holds the earliest trigger. Coverage-first arbitration states the fix once,
+in `MoreSpecificThan`. A parked clarify explaining zero tokens of "какая сейчас погода в
+Риме?" loses to a weather claim explaining all of them. Nobody has to encode that a parked
+clarify is less trustworthy than a grammar.
+
+**The limit.** The kernel prevents the class only where the losing claimant
+computes low coverage. Rome, V-567 and V-577 all qualify. Each is a stateful claimant
+swallowing an utterance it explains none of. A claimant that matches a substring does explain
+those tokens, and coverage does not catch it. V-567's substring match is that case from the
+other side. Coverage there has to be measured against the whole utterance rather than the
+matched span. `claimSpans` already does that, in the safe direction. So the kernel
+prevents most of the class and describes the rest. Claiming more would be dishonest.
+
+**It makes contention countable.** Today it is not. The 91-case fixture draws two stage-0
+grammars exactly once, at `ru-query-019`, and both route the same intent. Nobody knows whether
+contention is rare or whether the fixture omits it. An arbiter that sees every claim can
+count.
+
+**What it does not buy.** No accuracy point comes from this alone. Every number in
+`docs/evals/2026-08-05-routing-resident-model.md` is reachable without it. The kernel is a
+place to put the fix, not the fix.
+
+## What it costs
+
+Every seam rewritten is a chance to break a measured number.
+
+Re-measure the 91-case routing fixture. The baseline is 75.8% full and 80.2% intent-only at
+p50 1.19s, in `docs/evals/2026-08-05-routing-resident-model.md`. Judge against the classifier
+and the resident model, because those are what always answer.
+
+Re-measure Praxis reach. The baseline is 27/30 overall, 11/12 Praxis and 5/5 lifecycle, in
+`docs/evals/2026-08-05-praxis-reach.md`. The Praxis grammars are the only path to Praxis, so a
+reordering that demotes them costs every point.
+
+Re-run the nine-scenario interleave probe in `docs/evals/2026-08-06-claimant-interleave.md`.
+Six of nine pass today. That probe measures exactly what this proposal is for.
+
+Re-run the dialogue contract tests from V-563. They are whole multi-turn traces, and the only
+tests that cover the ladder as a ladder.
+
+Latency is the cheap part. A stage-0 query costs 3.7µs. One claim per claimant adds two slices
+and a token split, on a path whose p50 is over a second.
+
+The real cost is the arguments. Twenty-three comments across `buildRouter` and `querySources`
+explain why each entry sits where it does. A migration that turns them into rank integers and
+drops the prose destroys the only documentation the ordering has.
+
+## Migration order
+
+**Step one, no behaviour change. Delete the duplication.** Make `vetoOf` the single definition
+of the three structural holes. Have `gateLLMDecision` and `thinReason` read it. One rule,
+three consumers, no new abstraction. Re-measure the routing fixture and nothing else. This is
+worth landing whether or not the rest does.
+
+**Step two, the proof. Arbitrate the pre-route ladder.** Smallest seam, seven rungs, and the
+one with the measured defect. Each resolver returns a claim instead of a bool. The arbiter
+compares coverage, then band, then rank. The roster comes from the registry. The proof is the
+interleave probe reaching nine of nine with the routing fixture unmoved.
+
+**Step three, the query source chain.** Twenty-four sources, most of which already compute a
+match span. The personal boundary does not become a ranked claimant. It stays a hard stop, and
+the arbiter runs above it and below it separately. Re-measure Praxis reach and the search and
+Kiwix fallback.
+
+**Step four, stage 0, or not at all.** Twelve grammar groups whose order encodes twelve
+arguments, scoring 20/20 on the fixture. Most to lose, least to gain. Defer it until steps two
+and three have sat in the deploy long enough to break something.
+
+**`loop.Tick` moves last or never.** It already has the comparator, the gate with reasons, the
+loser trace and the loser rescue. Rewriting it to call a generic arbiter risks the digest path
+to gain a shared name.
+
+## What must not be in the kernel
+
+**Authorization.** This is the hard line. CLAUDE.md is explicit that LLM output is not
+authorization, and that a confirmation binds capability id, target entity, arguments,
+requester and expiry (`cmd/mavend/confirm.go`). A generic arbiter turns many opinions into
+one winner. That is the wrong shape for a binding. Make confirm a claimant with a rank and a band, and a claim that scored higher could take the
+turn from it. The binding would be softened into a comparison. Confirm may report to the record. It must not compete in the
+arbiter.
+
+The same rule covers the Hexis path. Free text never reaches a mutating call, and resolution
+happens against Nexus. Neither is a contest, so neither is arbitration.
+
+**The personal boundary.** Same reason, different currency. The boundary is not the most
+specific claimant. It is a stop. A boundary that can lose to a higher-coverage claim is not a
+boundary. The failure is the owner's notes reaching a search engine.
+
+**Confidence as a float.** The band exists because the measurement said a calibrated float is
+not available. The classifier scores 62% correct below its median and 62% above, over a spread
+0.083 wide. Its top-two margin has a p50 of 0.009
+(`docs/plans/19-dialogue-arbitration.md`). A kernel with a `Score float64` on the claim invites
+every claimant to invent one. When V-546 lands a softmax head with a calibrated probability,
+that number is read beside the bands, not squeezed inside them.
+
+**Slot extraction and validation.** `fillMatchedSlots` runs after a winner exists, and slot
+validation against the action schema is V-562. Both ask whether a claim is well formed. Neither
+asks which claim wins.
+
+## The second artifact: the ecosystem client
+
+The kernel is Maven's alone. The one thing here with plural clients by construction is the
+contract between the four services. Maven implements its side of it twice and a half.
+
+### Is the contract uniform today? No.
+
+Nexus and Praxis share one implementation. `ecosystemHTTP` (`cmd/mavend/ecosystem.go:62`) is
+embedded in both, so both get the same 10 second timeout, the same `setHeaders`, the same
+typed `ecosystemError`, and the same correlation key. Hexis is a separate client in another
+repository, vendored at `vendor/github.com/kami/hexis/pkg/client`, and it agrees on some of
+that and not the rest.
+
+Eleven divergences. Four of them are defects rather than style, and each is filed on its own:
+V-587 the 401, V-588 the unnamed Praxis service, V-590 the uncorrelated discovery hop, V-591
+the unsent causation id. They are ranked in that order, worst first, and none of them waits on
+this proposal. V-587 is the only one that makes the owner check the wrong thing.
+
+**A Hexis 401 is spoken as an outage.** Nexus and Praxis return `*ecosystemError` with
+`Unauthorized()`, `ContractMismatch()` and `Unreachable()` classifiers
+(`cmd/mavend/ecosystem.go:144`). Hexis returns `fmt.Errorf` strings
+(`hexis/pkg/client/client.go:157`). So `unauthorizedEcosystemError`
+(`cmd/mavend/ecosystem_acts.go:549`) does `errors.As` and always gets false for Hexis. The
+owner hears "Hexis is down" when the truth is that Hexis refused the credential. The comment
+at `ecosystem_acts.go:32` says that conflation must not happen.
+
+**The Hexis discovery hop is uncorrelated.** Hexis carries its own context key
+(`client.go:81`), invisible to Maven's. The bridge is a manual second stamp at
+`ecosystem.go:546`. `discoverCapabilities` (`ecosystem.go:527`) does not do it, and discovery
+runs before execute, so that call goes out with no correlation id. The doc comment above it
+claims the opposite.
+
+**Causation is computed and never sent.** `causationID` is derived at
+`ecosystem_acts.go:771`. Hexis supports `X-Causation-ID` (`client.go:147`). Nothing passes it.
+
+**A Praxis failure names no service.** `ecosystemGap` (`ecosystem_acts.go:36`) is the shared
+named-gap helper, and Nexus and Hexis call it. Praxis returns per-verb Russian strings instead
+(`ecosystem_acts.go:62`, `:73`, `:84`, `:95`). There is no `servicePraxis` constant. A Praxis
+outage and a Praxis 403 both say "не получилось", with the service unnamed.
+
+The rest are real but smaller. Hexis sends no `X-Requested-By: maven` and no `Accept` header,
+so Hexis cannot attribute a read call to Maven at all. Its timeout is 30 seconds against
+Maven's 10, which Maven cannot change from here. Its success predicate is `>= 400` where the
+shared client uses `!= 200`. `withToken` is duplicated verbatim per client because the
+embedded struct cannot return the concrete type. The version constant `"v1"` is defined twice,
+in two repositories, with nothing keeping the two equal.
+
+### Would a shared library have plural clients?
+
+**Partly verifiable, and the honest answer is that two of the three cannot be checked from
+here.**
+
+Hexis is verified. It is a Go module consumed through a `replace` directive, and it already
+publishes a Go client library that Maven imports. That is an existence proof that the pattern
+works for one of them.
+
+Praxis is suggested and not proven. Two comments reference Go paths in its repository
+(`cmd/mavend/factenrichment.go:4`, `cmd/mavend/ecosystem.go:365`). Nothing here compiles
+against it.
+
+Nexus is unverifiable from this repository. There is an HTTP base URL and some JSON shapes,
+and no language signal at all.
+
+So the claim that a shared library would have plural clients rests on one confirmed adopter
+and two assumptions. Do not present it as settled. The cheaper test is to fix Maven's side first,
+in Maven. Offer the package outward once it has proven itself on one caller.
+
+### What belongs in it
+
+The straw man is right, with one addition.
+
+- The correlation id, minted once per action, with one context key that all clients read. The
+  two-key split is the cause of the uncorrelated discovery hop.
+- Causation, since one of the three already supports it and the value is already computed.
+- The version header and `X-Requested-By`.
+- The timeout policy, as one number rather than 10 in one repository and 30 in another.
+- A typed error with the three classifiers, so a refused credential never speaks as an outage.
+- The named gap shape, so no client invents its own vocabulary the way Praxis did.
+
+### What must stay out
+
+**Authorization, for the second time and the same reason.** The confirmation binding is
+Maven's. It binds capability id, target entity, arguments, requester and expiry, and it lives
+in `cmd/mavend/confirm.go`. A shared client that offered a policy hook would invite each
+service to supply its own, and the binding would become configuration. Free text never reaches
+a mutating Hexis call, and entity resolution stays in Nexus. Neither belongs in a transport
+library.
+
+Retry stays out too, or nearly. The only retry Maven has is Nexus enrichment at the worker
+layer, with backoff from one minute to one hour (`cmd/mavend/factenrichment.go:49`). It is
+there because enrichment is a background job with no listener. A turn cannot retry, because
+the owner is standing there. A transport-level retry in a shared library would hide a
+second budget behind a turn that already has a name for failing.
+
+## The daemons must not get a framework
+
+The instinct is right, and half the work is already done in a way that shows why.
+
+Transport is shared and abstracted. `ipc.Dial` (`internal/ipc/client.go:94`) and `ipc.Listen`
+(`internal/ipc/server.go:202`) both go through `netaddr`. A bare path is a unix socket with
+`SO_PEERCRED` identity. A `tcp://host:port?token=...` address binds a network listener with a
+mandatory token. Callers pass a string and never branch on scheme. That seam made the
+workstation offload a deployment rather than a build. It is a library, it has nine clients in
+this repository, and it earns its weight.
+
+Startup is not shared, and should not be. There are twelve binaries under `cmd/`, each with a
+hand-written `main`, and no common lifecycle package. `cmd/mavend/main.go` runs 830 lines. The
+reason is visible in it. The daemon can boot **locked**, with no store at all, and wire its
+components later from inside an unlock handler. Thirteen subsystem pointers are pre-declared
+nil (`main.go:236`) and filled on one of two paths. The whole graph is built a second time
+inside the unlock path (`main.go:478`). A container owning object lifecycle would have to model
+a graph whose nodes do not exist at boot and may never exist.
+
+The deeper reason is a design property. Every daemon degrades alone, and every ecosystem
+client is nil unless configured. A wiring framework's job is to fail loudly when a dependency
+is missing. Maven needs the opposite: a missing dependency is a named gap in one answer and a
+working daemon everywhere else. An abstraction over startup would trade that property for a
+shorter `main`.
+
+The duplicated locked and unlocked wiring in `mavend` is a real defect and worth fixing. Fix it
+by extracting one function in that file. That is not a framework.
+
+## The honest comparison
+
+Spring and Django own object lifecycle and request handling for applications they have never
+seen. That is where the weight is paid for. The abstraction is general because the clients are
+unknown.
+
+Maven is one application, on one box, with one user. Its clients are known, there are nine of
+them, and they are in this repository. A framework here would be an abstraction with a census.
+
+So the right unit is a shared package and a convention. That is a smaller and more defensible
+claim. The evidence for its size is that both halves already exist in that form, and nobody
+called them a framework. `internal/ipc` is a shared package and a convention, and it carried
+the daemons off the box. `internal/decision` is a shared package and a convention, and it made
+the losers readable in one release. `internal/claim` is the third, written and waiting for a
+caller.
+
+The thing to disagree with: **the answer is two artifacts of different sizes. A package inside
+Maven, a library across the four services, and neither one is Spring.**

+# Plan: persist the routing trace
+
+**Owner's call, 06-08-2026. Vikunja #629, umbrella #628.**
+
+**Verdict: the per-turn decision record now persists.** That reverses a written decision,
+which is the point of this file. It is not an incidental telemetry
+feature. Do not read it as one.
+
+Last verified: 06-08-2026 @ 799cf55
+
+## What the old decision said
+
+`internal/decision` kept a 25-turn in-memory ring and persisted nothing. The argument was
+in `CLAUDE.md` and it was a good one. A turn record is read minutes after the turn or
+never, so a table that outlives the diagnosis buys nothing. His words did not belong in it.
+
+## Why it reversed
+
+V-546 replaces the generative router with classification heads on e5-small. Fitting
+prototypes and calibrating a distance both need real utterances. V-631 measured how few
+there are. Nine of the 31 modes in `internal/modes` have no seed example at all, and they
+are exactly the nine with no deterministic matcher. The seed corpus cannot supply them. A
+seed row is a phrase someone wrote for a matcher, not a thing he said. The 202 generated
+contrast pairs were tried and cost four points of fixture accuracy.
+
+So the choice was between no routing heads and a persisted trace. The owner chose the trace.
+
+## Retention, and why it is two answers
+
+**Raw trace: 14 days.** `store.RoutingTraceRetention` in `internal/store/routingtraces.go`. That
+is the life of a diagnosis with room for a weekend. The bound is an age and not a row
+count. The useful question is what she did this week, and a busy Tuesday must not push last
+Friday out.
+
+**A correction: indefinite.** The owner corrects a turn on `/chat` (V-630). The pair is then
+promoted out of the trace into a seed-shaped row and kept, because a label is not a
+transcript. What stays in `routing_traces` is the transcript. It expires on the same 14
+days as every other row, corrected or not.
+
+## What keeps it safe
+
+The utterance is stored in clear. A 384-dimension vector of a short sentence is
+substantially recoverable. Storing vectors instead would be a privacy claim we cannot
+support, and making it would be worse than staying silent.
+
+- **Nothing here leaves the box.** The rule that the owner's notes and facts are never
+  search input covers this table too. No query source reads it, and no upstream engine can.
+- **Retention is enforced on write and again at start.** `WriteRoutingTrace` prunes every
+  64th row, which is hours at human rate. `pruneTracesOnStart` covers the case write alone
+  cannot. A box that goes quiet keeps every row until the next sixty-fourth turn. Without
+  the start-time prune, the bound would hold only for a box in daily use.
+- **Deletion already exists.** `Store.Wipe` drops every table the database reports, so

+# Correcting a turn
+
+Last verified: 06-08-2026 @ 0d5bd0a
+
+V-630, under V-628. Reads with `21-persisting-the-routing-trace.md`.
+
+## Why a gesture and not a form
+
+The routing trace (V-629) stores every turn. Almost all of them routed correctly, so
+almost all of them teach nothing. A correction is the only high-value supervised signal
+the box produces. It is also the only one that costs the owner something to give.
+
+So the design constraint is the cost, not the schema. One gesture beside the reply. No
+form and no separate page.
+
+It is step-up gated like the chat POST beside it, which costs nothing: he tapped to send
+the turn he is correcting. It is gated because trace ids are sequential integers, and this
+is the one table the routing heads will be fitted on.
+
+## Two things to capture, and only one of them is required
+
+A correction has two halves.
+
+- This turn was wrong.
+- It should have been *this*.
+
+The second is worth much more. It names which boundary moved, and it is what a fitted
+head trains against. But requiring it would price out the first, and a turn marked wrong
+with no target is still a usable negative. So the target is optional. The trace carries
+`wrong` when he did not say.
+
+The target is one of the seven intents and never free text. V-632 fits prototypes from
+that table. An unroutable label would enter it, and a label nothing can score is worse
+than no label.
+
+## Where the label lives
+
+`routing_labels`, migration #24, keyed unique on the utterance. A second correction of
+the same sentence replaces the first, because his later answer is the one he meant.
+
+It is a separate table from `routing_traces` on purpose. The transcript expires after 14
+days. The label does not. A label is a sentence, an intent and an encoder id. That is not
+a transcript, and the reversal in doc 21 rests on the distinction.
+
+`was` is stored beside `should_be`. The pair is what names the confusion. A label with no
+`was` cannot say which boundary moved.
+
+## Reach
+
+`CorrectTurn(traceID, shouldBe)` takes no browser and no session. The trace id rides back
+on `ipc.ChatReply` through the same context sink the query source badge uses. Nothing in
+the seam assumes the web.
+
+Only `/chat` offers the gesture today. That is a gap, named rather than closed. If the web
+is the only place to correct a turn, the sample skews to whatever the owner types at. Voice
+is where the hard cases are. Telegram has the obvious shape, an inline keyboard on the
+reply. Voice does not. Inventing a spoken correction grammar would put a recogniser in
+front of the one signal that exists to fix recognisers. Both are follow-on work.
+
+## What is not decided
+
+Whether the owner ever wants to see the labels he gave. Nothing reads the table outward
+yet. `/trace` shows the ring, which is 25 turns and in memory, and a labels view is a
+different page with a different question.

+
+V-637, under V-628. Reads with `22-correcting-a-turn.md`.
+
+## What was missing
+
+Telegram was a reach and nothing else. `telegramsink` pushed an away message and the chat
+had no way to answer, so the correction gesture reached the web and voice only.
+
+That skews the labels. V-546 fits routing heads on them, and a sample drawn from wherever
+the owner happens to be sitting is the wrong sample.
+
+## Long-poll, not a webhook
+
+The box takes no inbound connections and reaches api.telegram.org through a relay, so the
+connection has to open outward. `getUpdates` with a 25 second hold, one goroutine in the
+daemon's WaitGroup.
+
+A failed poll waits 15 seconds and retries without escalating. The relay going down is the
+normal cause and it comes back on its own.
+
+## The backlog is dropped on start
+
+Telegram keeps undelivered updates for 24 hours. A daemon that was down overnight would
+otherwise wake and answer every queued message in order.
+
+That is worse than missing them. A question asked eight hours ago has been answered
+already. A reminder set from it lands at the wrong time. So the first call moves the offset
+past whatever is queued and acts on none of it.
+
+## One chat
+
+`ChatID` is the only accepted sender, and it is the same chat the push half already sends
+to. A message from anywhere else is dropped with no reply, because a reply confirms the bot
+exists and whose it is.
+
+Chat ids are not guessable. They are also not secret, since they travel in every forwarded
+message. So this is the whole authorisation and it is an allowlist of one.
+
+## The gesture
+
+Two taps at most. The reply carries one button, `не то`. Tapping it writes nothing and opens
+the seven intents plus `просто неверно`. The untargeted negative stays reachable, because he
+may have opened the row without meaning to name anything.
+
+Callback data carries the trace id and the target, under telegram's 64 byte cap. It comes
+off the wire. So an id that will not parse is dropped, and so is a target that is not one of
+the seven. A label nothing can score is worse than no label.
+
+A failed write says so on the button and leaves the keyboard up. A successful one takes the
+keyboard off, because a live keyboard on an answered turn invites correcting it twice.
+
+## The seam
+
+`NewPoller` takes two functions and no daemon type. `cmd/mavend/telegramintake.go` fills
+them from `ipc.CoreAPI`: `Chat` returns the reply and the trace id it collected off the
+context, and `CorrectTurn` writes the label. So a chat turn takes the path
+`POST /api/chat` already takes, and nothing in `internal/delivery` knows what a handler is.
+
+## What is not done
+
+The turn source is still `tap:text`, which telegram shares with the web. Provenance cannot
+tell a chat turn from a typed one, so a label's `source` column cannot either.
+That matters the first time someone asks whether corrections given in the chat differ from
+corrections given at the desk.
+
+Voice messages are ignored. The poller reads `message.text` and nothing else, so a voice
+note in the chat does not reach `mavsttd`.

+# No deadline on the turn path
+
+Last verified: 06-08-2026 @ 60e64dd
+
+**All four steps landed on 06-08-2026.** What follows describes the defect as it was and
+the work as it was planned. Two things came out differently. `Client.Close` read the conn
+field with no lock while `roundtrip` re-dialed and dropped it. `-race` caught that on the
+new cancellation test. So the conn field now has a mutex of its own, held only across a
+read or an assignment. And `/api/ptt` needed nothing: it proxies to the voice port and never
+touches the shared client, so only `/api/chat` got the extra connection. The pool inside
+`ipc.Client` is still unbuilt and still waiting on a second module measured queueing.
+
+V-638. Sibling of V-607, which is the same class of bug in `internal/worker`.
+Reads with `docs/offload.md` and `docs/protocol.md`.
+
+## What is missing
+
+A chat turn starts in a mavweb HTTP handler and ends at llama-server. Nothing between those
+two points can be cancelled, and one hop has a timeout.
+
+Four places, all on the same path.
+
+`voice.Replier.Reply` takes no context (`internal/voice/replier.go:41`). So `llmReplier`
+calls `PhraseReply(context.Background(), d)` at `cmd/mavend/replier_llm.go:42`. The turn
+cannot deadline its own reply. The only bound is `phraser.timeout`, 60s in deploy.
+
+`ipc.Client.roundtrip` sets no connection deadline (`internal/ipc/client.go:202`). A daemon
+that stops answering parks the caller for as long as the socket stays open.
+
+`ipc.Client.call` checks the context once, before sending (`client.go:149`), then blocks in
+`roundtrip`. Cancelling mid-call does nothing.
+
+`ipc.Server.serveConn` dispatches under `context.Background()` (`internal/ipc/server.go:253`).
+A client that hangs up does not cancel the turn, and neither does `Server.Close`.
+
+## And every call queues behind the slowest one
+
+`ipc.Client` serialises on one connection and one mutex. mavweb routes `/api/chat` and
+`/api/ptt` through the shared client, so one turn blocks all 28 handlers while it runs.
+Worst case is a 60s page load.
+
+This is understood for exactly one route already. `cmd/mavweb/main.go:57` opens a second
+connection for `/models`, and the comment there says why. A model swap is a multi-minute
+call, and sharing the connection would freeze every other page.
+
+## The pattern is already in the repo
+
+`internal/voice/client.go:101` derives a connection deadline from the caller's context,
+falls back to 120s, and clears it with a defer. `internal/ipc/client.go` never learned it.
+Copy that rather than inventing a second convention.
+
+## The work
+
+One commit each.
+
+**Context on the reply seam.** `phraser.Replier.PhraseReply` already takes a context and the
+interface has two implementations, so this is small. Change `Reply` to take a context, have
+`StubReplier` ignore it, and pass it through `llmReplier` to `PhraseReply`. Both call sites
+already hold one: `cmd/mavend/voice.go:461` and `cmd/mavend/clarify.go:574`.
+
+**Deadlines and cancellation on the client.** Pass the context into `roundtrip` and set
+`SetDeadline` from it. For cancellation mid-call, a watchdog goroutine that calls `c.drop()`
+on `ctx.Done()` is enough. `drop` exists, and the retry split already separates a lost write
+from a lost read. So a cancelled call lands in `errReadLost` and is never retried for a
+mutation. Check that against `internal/ipc/maperr_test.go`.
+
+**A request context on the server.** `serveConn` should derive from a server-scoped context
+so `Close` cancels a dispatch in flight. `Server` already carries `done` and a conn registry
+for this class of problem. The registry comment records what the last version of it cost:
+eleven days of stale ciphertext.
+
+**Stop serialising mavweb.** Give `/api/chat` and `/api/ptt` their own connection, the way
+`/models` has one. Roughly ten lines, and it changes no shared code.
+
+A connection pool inside `ipc.Client` is the general form and is deliberately not the first
+step. Each connection is already its own request and response stream. So a pool preserves
+frame pairing by construction. It still has to keep re-dial on drop, the
+`errWriteLost` and `errReadLost` split, and `Close`. Do the narrow fix, measure, and reach
+for the pool only if a second module turns out to queue.
+
+## How it is judged
+
+`make test` stays green. It is green at `06c1cf2`.
+
+Nothing here changes routing or recall, so `make eval-router` and `make eval-recall` are
+unchanged rather than re-measured.
+
+By hand: load `/dash` while a chat turn is in flight. Before the change it waits for the
+length of the turn.
+
+There is no test today that a cancelled context aborts an in-flight `ipc.Client` call. That
+absence is why two of these four went unnoticed, so the test is part of the work.
+
+## What is not done here
+
+The store is still `SetMaxOpenConns(1)` (`internal/store/store.go:99`) under WAL. WAL is
+built for concurrent readers against one writer, and the cap makes every read queue.
+`Store.DB(ctx)` hands the digestion worker a read transaction on that same connection. This
+plan does not touch it. It is measurable first and should be measured before it is changed.

+# The two boot paths have drifted
+
+Last verified: 06-08-2026 @ 69d0f5e
+
+V-639. Reads with `docs/operations.md`.
+
+## What landed
+
+`cmd/mavend/boot.go`. `newDaemonAPI(deps)` builds the CoreAPI with every field
+set, and `startBackground(ctx, &wg, deps)` starts the voice server and every
+worker through `goWorker`. `backgroundWorkers(deps)` is the pure list behind it,
+so a test can compare the set without standing a daemon up. Both paths in
+`run()` now read `coreAPI = newDaemonAPI(depsNow())` and one
+`startBackground(...)`, where `depsNow` reads whatever the current path wired.
+
+The shadowed `wg` is gone. Four tests in `cmd/mavend/boot_test.go`. Every
+`daemonAPI` field is set on a fully wired deployment. The handler gets the API
+it was built with. The worker set is asserted by name, at the full set and at
+the floor.
+
+Still by hand: unlock a locked box by passkey, ask something that needs Nexus,
+and check `/tools` lists the MCP servers.
+
+## What is wrong
+
+`run()` in `cmd/mavend/main.go` brings the daemon up two ways. A box with a key in the
+environment starts unlocked and wires everything at lines 280 to 621. A box without one
+starts locked. It wires the same things again inside the unlock closure, at lines 500 to
+579, after a passkey assertion.
+
+The two lists have drifted apart. Three ways.
+
+**Seven workers start untracked.** The unlocked path puts every one through
+`goWorker(&wg, ...)`, so `waitWorkers` at line 637 can wait for them. The unlock path
+starts `tl.run`, `factWorker`, `evalWorker`, `feedWkr`, `crawlWkr`, `mcp.run` and
+`home.run` as bare `go func()`. Nothing waits for any of them.
+
+That is the shutdown bug the code already documents at lines 631 to 636, reintroduced on
+the other path. The comment there records what it cost the first time. `run()` never
+returned, so `defer st.Close()` never sealed the database. The deployed ciphertext was
+eleven days stale before anyone noticed.
+
+**A shadowed WaitGroup hides it.** Line 529 declares `var wg sync.WaitGroup` inside the
+`if voiceW != nil` block, shadowing the one from line 359. It is `Add`ed and `Done`d and
+never waited. Reading the block, the voice server looks tracked. It is not.
+
+**Two `daemonAPI` fields are never set.** The unlocked path fills `nexus` at line 295 and
+`getMCPServers` at line 305. The unlock path fills neither. So after a passkey unlock,
+`ResolveEntity` answers `ErrNotImplemented` with a `nexus` block configured, and
+`MCPServers` answers empty with an `mcp` block configured.
+
+The second is the worse one. Empty is not a degraded answer, it is a wrong answer, and
+`/tools` renders it as "not configured".
+
+## Why it drifted
+
+`wireTelegramIntake` was added to both paths on 06-08-2026 (V-637) and it does use the
+outer `wg`, at line 519. So the newest line on that path is correct and the older ones
+around it are not. The path gets touched one line at a time and is never read whole.
+
+The shape of `cmd/mavend` is what allows that. It is 155 files and 9,551 lines of code.
+Six things live in it with no seam between them:
+
+- the handler
+- the action dispatch
+- the 19 query sources
+- the wiring functions
+- the six background workers
+- these two boot paths
+
+Nothing in the package makes the divergence visible.
+
+## The fix
+
+Make the two paths call one function instead of listing the same wiring twice.
+
+One `startBackground(ctx, &wg, deps)` that takes what it needs and starts every worker
+through `goWorker`. One `newDaemonAPI(deps)` that fills every field, including `nexus` and
+`getMCPServers`, so a field added later cannot reach one path and miss the other. Both
+call sites then read as one call each, and a future addition has one place to go.
+
+Delete the shadowed `wg` at line 529 as part of it.
+
+## How it is judged
+
+`make test` stays green.
+
+The regression that matters is a test asserting the two paths wire the same set. Compare
+the constructed `daemonAPI` field by field, and assert the worker count started under the
+outer `wg` matches. Without that, this drifts again the next time a wiring line is added.
+
+Then confirm on a locked box: unlock by passkey, ask something that needs Nexus, and check
+`/tools` lists the MCP servers. Both answer wrongly today.
+
+## Priority
+
+Latent, not live. `deploy/mavend.json` sets `db_key_env`, so homesrv boots unlocked and
+takes the correct path. This bites the locked deployment that `docs/operations.md`
+describes, and it bites silently.
