Measure CrisperWhisper 2.0 in Russian against the deployed floor (V-665)

Turbo in Intended mode scores 10.4% WER on 200 Golos crowd clips, against
27.5% for the ggml-small.bin the box loads today. It also beats its own base
model and CW2 large, which inverts what the card implies about turbo.

The mode choice is not settled by this corpus. Intended and verbatim disagree
on 29 of 200 after normalization, and the disagreement is script rather than
disfluency. Golos crowd carries almost no disfluency to disagree about.

whisper.cpp cannot load CW2: num_languages() derives from n_vocab and CW2's
51897 shifts seven special token ids. So the runtime is workpc under V-486,
with whisper on homesrv as the floor.

 recall. Training it in place couples routing accuracy to recall@1, with nothing in the
 suite to name the trade.
 
+**Two of those heads are trained as of 08-08-2026, and they are not the three
+above** (V-661, `docs/evals/2026-08-08-routing-heads-two-head.md`). Intent and
+destination share one masked mean pool. Destination scores a mean **80.8%** over
+three seeds, best **29/33 (87.9%)**. The classifier cascade scores 12/33 and the
+cascade with gemma-4-12b scores 24/33, so a 118M encoder beats the 12B teacher it
+was distilled from. Read the best run as one seed and not a headline, because one
+case is 3 points on a fixture this small.
+Recall is 15/15 and world is 5/5. Intent is 93.6% mean over three seeds. That is
+**not** comparable to the 76.0% and 84.4% those two arms scored: a softmax has no
+clarify class, so the head's fixture is the 88 cases carrying an intent.
+
+**A fourth head asks instead of guessing, same day** (V-661,
+`docs/evals/2026-08-08-clarify-head-four-head.md`). Clarify is not a value
+of intent, so a softmax cannot emit it. It is a second question over the
+same pooled vector: can Maven act on this at all. That is why the head's
+fixture was 88 cases and not 96. Over three seeds it catches **7.0 of the 8
+`want_clarify` cases and produces 2.3 false clarifies of 88**. The cascade
+today misses 1 and produces 2, so this is parity with no rules in front of
+it. Accuracy is the wrong number here and a head that never asks scores
+91.7%. Confidence is the other half. Max softmax over the intent head reads
+**0.851 where it is right against 0.604 where it is wrong**, ranking right
+above wrong in 83.4% of pairs. `Confidence: 1.0` was a hardcode, and this
+replaces it with a signal. The two are not the same signal: one says which
+intent is unclear, the other says the utterance carries too little to act
+on. **The fourth head is not free the way the third was.** Intent,
+destination and slot F1 each move down one to four points, inside the seed
+spread. `поужинал` is a false clarify on every seed, which is the same
+defect `thinSingleToken` was narrowed for on 2026-08-01.
+
+The corpus for it is generated, because every existing row is answerable by
+construction. **The router-prompt agreement filter cannot work here**, since
+`routeGrammar` has no clarify value and a generated line always agrees with
+itself. A gemma judge replaces it. The first judge called 24 of 40
+answerable rows underspecified, because it judged against a generic
+assistant rather than against Maven's contract.
+
+**Mood is cut, not deferred.** The enum describes her own reply state, not the
+speaker's emotion, and no dataset maps onto it.
+
+**A third head landed the same day** (`docs/evals/2026-08-08-slot-head-three-head.md`).
+BIO slot tags had no Maven-domain corpus, which was true of found corpora and
+false of made ones. `label_slots.py` distils spans out of gemma-4-12b under a
+GBNF closed over Maven's own five slots. A span survives only when it is a
+literal substring of the utterance, so the agreement filter costs no second
+call. 2178 spans over 1702 rows, 37 dropped, nothing unparsed. Three heads score
+intent **92.8%**, destination **82.8%** and slot span F1 **72.4%** over three
+seeds. The slot head is free: both other numbers move less than their own seed
+spread. Epoch selection reads the intent dev slice alone. Slot F1 is still
+climbing when it stops, which costs about 4 points.
+
+The MASSIVE warm-start of step 2 is worth nothing here. Stock e5-small ties it on
+intent and leads by a third of a case on destination. Nothing argues for keeping
+that step.
+
+The floor was a corpus defect and it is fixed. The first 120 floor rows carried
+one sentence shape, so the head named a destination where the fixture says walk
+the chain. Rotating six shapes took the floor 3/7 to 6/7 and destination 75.8% to
+80.8%. What is left is calendar at 3/6 on every seed, which training cannot move:
+the possessive agenda rules claim those cases at stage 0 and name nothing, so no
+label reaches the head. That is the same trade V-660 flagged and it wants the
+owner's call.
+
+**Nothing of this runs in Go.** The weights are `heads.pt` and `out/body_heads/`
+on workpc. Reaching the daemon needs an ONNX export and a caller. The resident
+e5-small must not be replaced by the copy, because recall depends on that file.

+(V-659, `docs/evals/2026-08-08-destination-fixture.md`). This section used to say
+it had neither. `want_source` on `eval.Case` is a pointer, because the destination
+has three states and a bare string has two. Absent is every intent but query,
+which never reaches `queryWalk`. Present and empty is the `SourceUnknown`
+contract: name nothing and walk the chain. Present and named is a destination the
+route must produce. Thirty-three of ninety-six cases carry one.
+
+A destination miss does **not** fail the case. It lands in `Outcome.SourceReason`
+and never in `Reasons`, so `Accuracy` and `IntentAccuracy` mean what they meant
+and `SourceAccuracy` is a second number over the labelled cases only. Intent and
+destination are two decisions, and one number hides which one moved. A route that
+lost its intent scores no destination hit, or a clarify would satisfy an empty
+label for free.
+
+Measured classifier+ONNX: intent **73/96 (76.0%)**, destination **12/33 (36.4%)**.
+The split is the finding. World is 5/5, because a stage 0 rule names it. The
+`SourceUnknown` floor is 5/7. Calendar is 2/6, because the possessive agenda
+rules deliberately do not name it. And **recall is 0/15, because nothing
+anywhere names it**. Those turns are still answered, since the chain walks
+recall early. Recall is the number the fourth head has to move.
+
+Seven cases assert the floor and five of them are homelab operations. They
+cluster because `SourceRecall`, `SourceNetwork` and `SourceAttention` overlap on
+every question about the box. The other two are `ru-query-005` and
+`ru-query-014`. No query source reads the reminder store, and a deadline could
+sit in tasks, the calendar or Praxis. `mavpoll` writes its netdata and uptime-kuma
+observations into the fact store recall reads. That is a finding about the enum,
+not a gap in the labelling. The owner confirmed all seven floor labels on
+08-08-2026, so they are a decision rather than an agent's guess.
+
+`baselineGrammars` in `eval_test.go` mirrors `buildRouter` and had drifted:
+`WorldQueryGrammars` was wired into the daemon by V-655 and not into the mirror,
+so the fixture scored a grammar set nobody runs. Fixed by V-659, worth 3 points of
+destination and nothing else. Check that function when adding a grammar.
+
+**The model arm landed the same day** (V-660,
+`docs/evals/2026-08-08-destination-model-arm.md`). `routeGrammar` carries a
+`source` rule closed over `router.Sources` plus the empty floor, so the model
+cannot emit a destination that does not exist. The prompt lists the twelve in
+Russian and says `""` is a normal answer to give often. `LLMRouter.Route` reads it
+back through `ValidSource` and on `IntentQuery` alone. Against gemma-4-12b on the
+workstation the cascade scores destination **24/33 (72.7%)** with intent unmoved
+at 84.4%, and **recall goes 0/15 to 14/15**. The resident Qwen3-1.7B is
+unmeasured, because it binds `--port 0` inside the container.
+
+**Stage 0 now costs four destination points.** It did not before. The four cases
+the cascade loses and the model alone wins are all calendar. The possessive
+agenda rules claim them first and name nothing on purpose. That caution was free
+while nothing downstream could name anything either. It is not free now, and the
+fix is the owner's call rather than a quiet edit.
+
+The last arm is V-546. Intent, mood and BIO slot tags were already three heads on
+one forward pass of the resident e5-small. Destination is a fourth head on the
+same pass, and 72.7% from a 12B teacher is the label source for training it.

+# A clarify head, and a confidence that is not a hardcode
+
+Measured 2026-08-08 on workpc, the same day and the same fixtures as
+`2026-08-08-routing-heads-two-head.md` and `2026-08-08-slot-head-three-head.md`.
+New script `gen_clarify.py`, new fixture `eval_fixture_clarify.jsonl`.
+
+## A softmax has no clarify class
+
+That sentence closed the two-head measurement. It is why the head's fixture was
+88 cases and not 96. The eight `want_clarify` cases sat outside every number
+measured, and the head had no way to produce the answer they wanted.
+
+A fourth head is the answer. Clarify is not a value of intent. It is a second
+question asked of the same pooled vector: can Maven act on this at all.
+
+## The corpus had one class
+
+Every row in `train_heads_slots.jsonl` was generated FOR an intent or a
+destination. So every row is answerable by construction. A head trained on that
+alone sees one class and learns to say yes.
+
+`gen_clarify.py` makes the other class. Five shapes, ten topics. The shapes are
+the gate's own reasons in `gateLLMDecision` plus the two the fixture carries:
+bare noun, bare verb, demonstrative, deictic time, dangling reference.
+
+**The agreement filter that worked for destination cannot work here.**
+`routeGrammar` has no clarify value. So the router always names an intent, and
+any generated line always agrees with itself. The second pass is a judge
+instead. Gemma is asked, without seeing the label, whether Maven would have to
+ask a question back.
+
+## The first judge was worthless and the second was measured
+
+The first judge said "needs clarify" on 24 of 40 plainly answerable corpus
+rows. It flagged `запиши что я пообедал` and `Покажи расписание поездов на
+вечер`. It was judging against a generic assistant, one that asks "where?"
+about lunch. Maven writes that note.
+
+Rewriting it to state what she can already do took false positives to 16 of 60.
+It also catches all eight fixture clarifies. So the judge discriminates.
+
+On the generated pile it removed 7 of 306, a 97.7% keep rate. That is not the
+judge failing. The generator is aimed at underspecified lines, so there is
+little for a filter to catch. The 27% false-positive rate is the number to
+quote, and it is label noise on the positive class.
+
+**Both passes are gemma-4-12b.** Generation and judging. So the corpus is
+gemma's opinion of what is underspecified, and the head distills that opinion.
+What keeps it honest is the fixture. Those eight cases were written by the owner
+and gemma never saw them.
+
+299 rows kept, against 3604 answerable. The positive class carries `intent:
+null`, so it costs the intent head nothing.
+
+## Result
+
+Three seeds, 24 epochs, epoch still chosen on the intent dev slice.
+
+| | two heads | three heads | four heads |
+|---|---|---|---|
+| intent mean | 93.6% | 92.8% | 91.7% |
+| destination mean | 80.8% | 82.8% | 79.8% |
+| slot span F1 mean | — | 72.4% | 68.3% |
+| clarify caught | — | — | 7.0 of 8 |
+| false clarifies | — | — | 2.3 of 88 |
+
+**The fourth head is not free the way the third was.** Intent, destination and
+slot F1 all move down. The drop is one to four points, and the seed spread is
+wide enough to contain it. Seed 2 scores intent 94.3% and destination 84.8%, both above
+every three-head seed. Read the drop as unproven rather than as absent.
+
+Accuracy is the wrong number for this head and is reported for completeness at
+95.8% to 96.9%. Eight of ninety-six cases are positive, so a head that never
+asks scores 91.7%. Recall on those eight is the number.
+
+Compare it to what ships. The cascade today misses 1 clarify and produces 2
+false ones. The head catches 7 of 8 and produces 2.3 false ones. That is
+parity, from a 118M encoder with no rules in front of it.
+
+The saved checkpoint is seed 2 at epoch 10. Intent 94.3%, destination 28/33,
+slot F1 73.6%, clarify 7 of 8 with 3 false. `heads.pt` carries four state dicts.
+
+## What it gets wrong is consistent across seeds
+
+`поужинал` is a false clarify on all three seeds. That utterance is already
+recorded as a real defect. `thinSingleToken` was narrowed on 2026-08-01 to spare
+a token carrying a Russian verb ending. One word is routinely a whole sentence
+in Russian. The head relearned the mistake the rule was narrowed to
+fix.
+
+`что дальше?` is a false clarify on two seeds. That one is a disagreement rather
+than an error. The utterance is underspecified, and V-498 decided stage 0 claims
+it for the calendar on purpose.
+
+`ну это` is missed on two seeds. `amb-003` is the shortest case in the fixture
+and the generated demonstratives are longer.
+
+## Confidence
+
+`Confidence: 1.0` was a hardcode in `llmrouter.go`, so a correct low confidence
+could not exist. Max softmax over the intent head is the replacement. It is only worth reading
+if it is lower where the head is wrong.
+
+It is. Mean 0.851 where the head is right against 0.604 where it is wrong. It
+ranks a right case above a wrong one in 83.4% of pairs.
+
+So there are two signals now and they are not the same signal. Confidence says
+the head is unsure which intent this is. The clarify head says the utterance
+does not carry enough to act on. A confident wrong route and an honest "I cannot
+tell" are different failures, and one number cannot report both.
+
+## What this does not measure
+
+The same gap as every head run. **Nothing of this runs in Go.** Four heads
+instead of three does not change that.
+
+There is no threshold. Both signals are reported as raw numbers. Turning either
+into a gate needs a decision about where to cut, and that trades false clarifies
+against wrong acts. The fixture has 8 positives, which is too few to fit a
+threshold on.
+
+The 299 generated rows have no held-out slice of their own. Clarify is scored on
+the fixture alone.

+# 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 five of them cluster
+
+The five 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.
+
+All seven were written by an agent and confirmed by the owner on 08-08-2026.
+
+## 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.

+
+## The gap was structural
+
+V-659 measured the destination at 12/33 on the classifier cascade, with recall
+at 0/15. Nothing in `routeSystem` named a `Source` and `routeGrammar` could not
+emit one, so the resident model had no string to write. That is the shape V-517
+measured for Praxis reach at 0/12: not a weak model, an absent contract.
+
+`routeGrammar` now carries a `source` rule closed over `router.Sources` plus the
+empty floor. The prompt lists the twelve destinations in Russian and says that
+`""` is a normal answer to give often.
+
+## Result
+
+| run | intent | destination |
+|---|---|---|
+| classifier + ONNX (V-659) | 73/96 (76.0%) | 12/33 (36.4%) |

+| cascade + gemma-4-12b + hash fallback | 81/96 (84.4%) | 24/33 (72.7%) |
+
+Recall is the move: 0/15 to 14/15. Intent did not shift, which was the
+constraint. The prompt is shared, so a destination rule that costs routing
+points is not a win.
+
+The eight llm-only errors are the eight `want_clarify` cases. The model returned
+`unknown` on every one, which is correct, and the llm-only harness surfaces a
+decline as an error by design.
+
+## Stage 0 now costs four destination points
+
+The four cases the cascade loses and the model alone wins are all calendar. The
+possessive agenda rules claim them at stage 0 and deliberately name nothing.
+"что у меня в списке покупок" matches the same rule. Naming the calendar there
+would take the list source off the turn (V-655).
+
+So a rule written to be careful about the list now blocks a model that would
+have named the calendar correctly. Before V-660 that caution was free, because
+nothing downstream of stage 0 could name anything either.
+
+Three ways out, and each costs something. Split the possessive rule so the
+calendar-shaped half names its destination. Let a later stage overwrite an empty
+destination a grammar left behind, which reverses "a matched value always wins".
+Or leave it, on the argument that four points is cheap next to a wrong
+destination on a shopping list. This wants the owner's call rather than a quiet
+edit.
+
+## What this does not measure
+
+The resident Qwen3-1.7B, which is what homesrv runs. It binds `--port 0` inside
+the container and no host process can reach it. Scoring it needs a second
+llama-server on a fixed port. The workstation is never assumed
+up, so the homesrv number is the one that decides whether this ships on by
+default.
+
+The fixture is 33 labelled destinations over twelve values. Recall carries 15 of
+them and five destinations carry none at all. A per-destination number below
+world, recall, calendar and the floor is not supported by this fixture.

+# 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.

+# The parked clarify ride, bounded and re-measured
+
+Date: 2026-08-08, V-663. Same 140 turns, same driver, third and fourth runs of
+the day. Before is `d6f3914`, after is that plus two changes.
+
+## What was measured before
+
+One question about a reminder's day rode turns 6 to 13. It ended only because
+turn 14 was a new request. Two of those turns are the worst replies in the
+corpus:
+
+```text
+спасибо   -> Сейчас 21:25. В какой день?
+привет    -> Сейчас 21:25. В какой день?
+```
+
+V-654 had already added `MaxSuspends` and the tail count had not moved.
+
+## Why three bounds let it happen
+
+The TTL, `MaxAttempts` and `MaxSuspends` all exist and all were rearmed.
+
+An aside spends no attempt, so `MaxAttempts` never reaches it. A turn reading as
+a failed answer zeroes `Suspends`, so `MaxSuspends` never reaches the asides.
+`спасибо` read as a failed answer. So the pleasantry both produced the reply
+above and paid for it out of the budget meant to end the ride.
+
+## The two changes
+
+`PendingQuestion.Rides` counts the same event as `Suspends` with the resets
+taken out. Set once, incremented only in `noteSuspended`, carried across the
+re-park in `askRemainingGap`. `MaxRides` is 4, one looser than `MaxSuspends` so
+that the tighter statement about a run stays reachable.
+
+A pleasantry is an aside, not a failed answer. The set is a new closed lexicon
+entry, matched as whole utterances rather than tokens. `вечер` answers `это утра
+или вечера?` and `нет` answers a confirm. Anything that could fill a slot stays
+out.
+
+## Result
+
+| | before | after |
+|---|---|---|
+| turns carrying a clarify tail | 21 | 17 |
+| turns carrying any failure string | 31 | 29 |
+| the longest ride | 8 turns | 4 turns |
+
+The turns carrying a tail, by number:
+
+```text
+before  6 7 8 9 10 11 12 13   53 54 55 56 57   99 102 103   116   136 137 138 139
+after   6 7 8 9                53 54 55 56 57   99 100 101   116   136 137 138 139
+```
+
+Turn 10 is the change. It now reads:
+
+```text
+спасибо -> Прошлую просьбу отпускаю. Пожалуйста, я всегда готова помочь тебе.
+```
+
+She lets the request go, says so, and answers the man. Turns 11 to 13 are clean.
+
+**`MaxRides` is not what fired.** The pleasantry is an aside now, so it no
+longer breaks the run. `MaxSuspends` reached three on turn 10 and ended it.
+`Rides` is the backstop for the shape where an answer really does break the run.
+No turn in this corpus reaches it.
+
+## What did not move
+
+Four rides are untouched. Turns 53 to 57 are five consecutive asides against a
+reminder missing its day. Turn 58 is a new request that drops it. Nothing
+pleasant appears in that run, so neither change applies. Turns 99 to 101 shifted
+by one, and 116 and 136 to 139 are unchanged.
+
+So the fix is worth four turns of twenty-one. What is left is asides against a
+question the owner never answers. `MaxSuspends` was written for that shape and
+does bound it, at four turns each.
+
+## Not attributable
+
+Latency moved p50 1.1s to 1.5s and p95 2.8s to 3.0s, and the 34.3s outlier in
+the earlier run is gone. Both runs had the workstation up. Read none of it as
+caused by this change.
+
+One unrelated defect appeared in the after run and is recorded here because it
+is visible in the transcript. Turn 4 answered `Я записала твою привычкуRegarding
+coffee without sugar.` That is English leaking into a Russian reply with no
+space in front of it. It is a phrasing defect and it has no task yet.

+# Two heads on e5-small, and the first destination the router did not need a model for
+
+Measured 2026-08-08 on workpc (Radeon RX 7900 GRE, ROCm). Covers V-661, step 3 of
+`docs/plans/18-routing-heads-on-e5-small.md`. Workspace is `~/Programs/embed-training`,
+scripts `gen_query_source.py`, `label_source.py`, `build_heads_corpus.py`,

+
+## Two heads, not four
+
+Intent is 7 classes and destination is 12 plus the `SourceUnknown` floor, sharing
+one masked mean pool over one forward pass. The plan asked for four. Two of them
+have no labels and neither is a GPU problem.
+
+**Mood is cut, not deferred.** Maven's enum is `neutral, happy, thinking, tired,
+confused` and it describes her own reply state, not the speaker's emotion.
+`psytechlab/EmpatheticIntents-ru` was the only candidate and its 32 emotion
+labels do not map onto it. There is nothing to train against.
+
+**BIO slot tags stay in the MASSIVE body.** No Maven-domain span corpus exists.
+`2026-08-08-massive-warm-start.md` records that no second Russian slot-filling
+corpus is reachable at all.
+
+The destination loss is masked with `ignore_index`. Only a query turn reaches
+`queryWalk`, so a reminder contributes nothing to it.
+
+## Where the destination labels came from
+
+V-660 taught the router prompt to name a destination. That made gemma-4-12b a
+teacher, and this distils it.
+
+Labelling the 300 query rows already in `train_v5.jsonl` gave 277 destinations.
+The shape was unusable: the floor 101, calendar 62, recall 47, and `feeds` and
+`attention` at zero. A 13-way softmax cannot learn a class with no examples.
+
+`gen_query_source.py` is the destination half of `gen_corpus.py` and runs the
+same two passes. Gemma writes questions whose answer lives in one named place.
+The daemon's own `routeSystem` prompt then routes each one back. A line survives
+only when the intent is `query` **and** the source is the destination it was
+generated for. The glosses are copied verbatim out of `route_system.txt`, so the
+generator and the labeller work from one definition.
+
+The prompt and the GBNF are dumped from `internal/router/llmrouter.go` by
+`TestDumpPrompt`, never retyped. The workspace held its own copies and V-660
+changed both.
+
+1229 kept of 2373 generated, 51.8%. Merged corpus is 3664 rows carrying 1727
+destinations:
+
+| | rows | | rows |
+|---|---|---|---|
+| the floor | 220 | world | 132 |
+| calendar | 180 | money | 126 |
+| tasks | 169 | list | 124 |
+| recall | 167 | self, feeds, attention | 120 each |
+| weather | 136 | network | 103 |
+| | | home | 50 |
+
+`home` is thin because the agreement filter rejected most of what was generated
+for it. A question about the house routes `act` more often than `query`. That is
+the filter working, and 50 is the finding rather than a shortfall.
+
+**The floor was regenerated once.** The first 120 rows carried one sentence
+shape across eight topics. That shape was "что там с X" and its two synonyms.
+Every named destination varied and only the floor collapsed. The reason is that
+the generator varies a topic, and ambiguity is not a topic.
+
+`gen_query_source.py` now rotates six floor shapes. A `почему` question, a yes
+or no question, and a question carried by intonation alone. Then a
+better-or-worse question, a status question, and an existence question. That is
+a fix to degenerate generation. It is not fitting to the fixture, whose floor
+cases are homelab operations and match none of the six.
+
+The 1229 generated rows carry `intent: null`. Every one is a query by
+construction. There are five times as many as the corpus has query rows, so
+including them would make query half the intent corpus.
+
+## Result
+
+Three seeds, two bodies, epoch chosen on the intent dev slice and never on a
+destination number.

+| stock `multilingual-e5-small` | one shape | 93.6% | 76.8% |
+| warm-started `out/body_massive` | six shapes | 93.6% | **80.8%** |
+
+Best single run is destination **29/33 (87.9%)**, seed 0 on the rotated floor.
+Peak 1.68GB of 17.2GB, under four minutes end to end.
+
+Against the two arms already measured on the same 33 labelled cases:
+
+| | destination |
+|---|---|
+| classifier cascade (V-659) | 12/33 (36.4%) |
+| cascade + gemma-4-12b (V-660) | 24/33 (72.7%) |
+| two heads on e5-small | 29/33 (87.9%) |
+
+A 118M encoder beats the 12B teacher it was distilled from, on the fixture. The
+per-destination split is where it happens: **recall 15/15** and **world 5/5**.
+Recall was 0/15 on the cascade and 14/15 through gemma.
+
+Read 87.9% as one seed of a mean of 80.8%, not as a headline. Three seeds score
+29, 25 and 26 of 33. One case is 3 points on a fixture this small.
+
+Intent is **not** comparable to the 73/96 and 81/96 figures those two arms
+scored. A softmax has no clarify class. The head's fixture is the 88 cases that
+carry an intent, and the 8 `want_clarify` cases are scored separately below.
+
+## The MASSIVE warm-start is worth nothing here either
+
+Step 2 measured it at +0.4 points of intent accuracy and called that inside seed
+noise. Destination was the open question, because MASSIVE has a
+`definition_word` slot that looked like a `SourceWorld` signal sitting in a head
+already trained.
+
+It is not. The two bodies score the same intent mean to one decimal. Stock is
+one point ahead on destination, which is a third of one case. Nothing here argues
+for keeping the warm-start step. Dropping it removes a dependency on a corpus
+pull that `datasets` 5.0 cannot do.
+
+## The floor moved, calendar did not
+
+Before the rotation, all seven misses at seed 0 were the floor and calendar. The
+head named a destination where the fixture says walk the chain, and it was
+confident doing it. `"почему сервер тормозит"` read `world` at 0.80.
+`"хватает ли места под новые бэкапы"` read `network` at 0.82. Those are the five
+homelab cases V-659 flagged, where `SourceRecall`, `SourceNetwork` and
+`SourceAttention` all overlap. `mavpoll` writes its observations into the fact
+store recall reads.
+
+| | one shape | six shapes |
+|---|---|---|
+| the floor | 3/7 | 6/7, 6/7, 5/7 |
+| calendar | 3/6 | 3/6, 3/6, 3/6 |
+| recall | 15/15 | 15/15 at seed 0 |
+| world | 5/5 | 5/5 |
+
+The floor was a corpus defect and it cost 3 cases. Sentence variety carried it,
+not homelab vocabulary, which the training rows still do not contain.
+
+**Calendar is 3/6 at every seed and is a different problem.** It is the shape
+V-660 named. The possessive agenda rules claim those cases at stage 0 and
+deliberately name nothing, so no destination label reaches the head. Training
+cannot move a case the head never sees. That one wants the owner's call.
+
+## Max softmax separates, weakly, and the gate stays
+
+The plan argues max softmax is a calibratable confidence where `Confidence: 1.0`
+was a hardcode. Measured on the intent head:
+
+| | n | mean confidence |
+|---|---|---|
+| correct | 80 | 0.897 |
+| wrong | 8 | 0.705 |
+| `want_clarify` | 8 | 0.685 |
+
+The softest correct answer is 0.66 and 3 of 8 clarify cases sit below it. So a
+single cut buys three clarifies at no false-clarify cost, and no more.
+
+The other five explain themselves. `"напомни"` scores 0.94 as `reminder` and
+`"сделай это"` scores 0.80 as `act`. Both are intent-certain and slot-empty, and
+confidence was never the signal there. `gateLLMDecision` already catches exactly
+that shape, an act with no allowlisted fn or a keyless fact, and it keeps doing
+so. The head replaces the hardcode. It does not replace the gate.
+
+## An incident worth recording
+
+The first generation run produced zero rows for eight destinations. `mavgpud`
+yields the card when another process wants it (V-488) and llama-server answers
+503 until the model is back. Every generate call inside that window burned one of
+the destination's batches. The run walked its own cap without a single successful
+call. The log said `503` 260 times, and the summary line said 64.1% keep rate,
+which read as success.
+
+`call()` now retries a 503 with backoff. A generator that treats an unloaded
+model as a bad generation is a silent-corpus bug, not a slow one.
+
+## What this does not measure
+
+**Nothing here runs in Go.** The heads are a `heads.pt` and an
+`out/body_heads/` on workpc. Reaching the daemon needs an ONNX export and a
+caller. The resident e5-small must not be replaced by this copy: recall depends
+on that file, and `EmbedQuery`/`EmbedPassage` are its contract.
+
+The destination fixture carries 4 of 13 classes: recall 15, floor 7, calendar 6,
+world 5. `tasks`, `money`, `list`, `home`, `network`, `feeds`, `attention` and
+`self` have no gold case. So 78.8% is silent on eight destinations that together
+hold 800 training rows.
+
+Latency was not measured. A forward pass of a 118M encoder should beat a 1.7B
+decoder on a query turn. That is arithmetic, not a number from this box.

+# A slot head, and the corpus that did not exist this morning
+
+Measured 2026-08-08 on workpc, the same day as `2026-08-08-routing-heads-two-head.md`
+and against the same fixtures. Workspace is `~/Programs/embed-training`, new
+scripts `slot_grammar.gbnf`, `slot_system.txt`, `label_slots.py`, `merge_slots.py`.
+
+## The corpus was the whole problem
+
+The two-head measurement said BIO slot tags stay in the MASSIVE body, because no
+Maven-domain span corpus exists. That was true of found corpora and false of
+made ones. Destination had the same shape at breakfast. V-660 gave gemma-4-12b a
+string to write and the label problem became a generation problem.
+
+The same trick applies to spans. `slot_grammar.gbnf` emits a list of
+`{"slot": ..., "text": ...}` and the enum closes over Maven's own five: `time`,
+`text`, `key`, `value`, `fn`. `slot_system.txt` demands each span be an exact
+substring of the utterance.
+
+**The agreement filter is free here.** Destination needed a second pass. The
+daemon's own router prompt had to route each generated line back. A span needs
+no second call. It either occurs in the utterance or it does not, and
+`label_slots.py` drops it with `find()`.
+
+1702 rows labelled from `train_v5.jsonl`, the reminder, fact, note, act and
+query intents. Chat and system carry no slot and were never asked.
+
+| slot | spans |
+|---|---|
+| text | 1175 |
+| time | 485 |
+| fn | 381 |
+| key | 72 |
+| value | 65 |
+
+37 spans dropped as not-a-substring, 2.2% of the pile. Nothing failed to parse,
+which is the grammar doing its job. 409 rows came back with no span at all.
+Those are kept and tagged all `O`. An utterance carrying no slot teaches the
+head not to invent one. An empty list is a label and not a miss.
+
+`key` and `value` are thin because they come from facts alone. That is the
+shape of the corpus, not a labeller failure.
+
+## Three heads on one forward pass
+
+Intent and destination were already two linear heads over one masked mean pool.
+Slots is a third head over the per-token states of the same pass, so the marginal
+cost is one `Linear(384, 11)`.
+
+The tag set is `O` plus `B-` and `I-` for each of the five. A softmax cannot
+emit a tag that does not exist. That is the structural guarantee the GBNF buys
+for the teacher, and the head gets it for free.
+
+Two masking rules, both `ignore_index`. A row with no `spans` key contributes
+nothing, which covers the 1900 generated destination rows and every chat and
+system turn. A padding or special-token position contributes nothing either.
+
+Scoring is exact-match span F1, not token accuracy. Most tokens are `O`, so a
+tagger that predicts nothing anywhere scores above 90% on tokens.
+
+## Result
+
+Three seeds, 24 epochs, epoch chosen on the intent dev slice alone.
+
+| | two heads | three heads |
+|---|---|---|
+| intent mean | 93.6% | 92.8% |
+| destination mean | 80.8% | 82.8% |
+| destination best | 29/33 (87.9%) | 29/33 (87.9%) |
+| slot span F1 mean | — | 72.4% |
+
+**The slot head costs nothing and adds a third decision.** Intent moves 0.8
+points down and destination 2 points up. Both sit inside the seed spread those
+two numbers already had. Read this as unchanged, not as a trade.
+
+The saved checkpoint is seed 1 at epoch 10: intent 93.2%, destination 81.8%,
+slot F1 75.8%. `heads.pt` now carries three state dicts and the `bio` list
+beside the intent and source enums.
+
+## Epoch selection is now wrong for one of the three heads
+
+Slot F1 was still climbing when the intent-selected epoch stopped it. Seed 0
+selects epoch 13 at 70.9% and reaches 76.1% at epoch 20. Seed 1 selects epoch 10
+at 75.8% and reaches 80.0% at epoch 24.
+
+So the three tasks want different epochs and the harness picks one. Two ways
+out, and neither was taken here. Select on a joint score, which needs an
+argument about weights. Or give the slot head its own dev slice and its own
+early stop, which means the heads stop being one checkpoint.
+
+Leaving it costs about 4 points of slot F1 and nothing else. The router
+contract is graded on intent. Selecting on it is the conservative choice rather
+than an oversight.
+
+## What this does not measure
+
+The same gap as the two-head run. **Nothing of this runs in Go.** Three heads
+instead of two does not change that. It does change the export. The slot head
+reads the per-token states, so an ONNX graph exposing only the pooled vector is
+not enough.
+
+There is no held-out span fixture. Span F1 is measured on the dev slice of the
+same distilled corpus, so it scores agreement with gemma rather than
+correctness. The V-572 defect utterance, `"напомни в 11:00 позвонить маме"`, is
+labelled correctly by the teacher, but one utterance is not a fixture.
+
+`key` at 72 spans and `value` at 65 are too thin to report a per-slot number.

+       [3.3s t=309]
+
+YOU:   почему интернет медленный?
+MAVEN: вот что я нашла: интернет может работать медленно из-за плохого сигнала из-за удаленности вышки, исчерпанного лимита трафика по тарифу, нахождения вне зоны покрытия 4G/LTE, устаревшей или неисправной SIM-карты, а также из-за сбоя в настройках роутера.

+       [2.6s t=313]
+
+YOU:   что такое NAT?
+MAVEN: вот что я нашла: NAT (Network Address Translation) — это технология в сетях TCP/IP, которая позволяет изменять IP-адрес в заголовке пакета при его прохождении через устройство. Она перенаправляет трафик между локальной и глобальной сетями, позволяет объединять устройства в локальной сети под одним публичным IP-адресом, а также скрывает сеть и экономит IP.

+# The same fortnight, after V-655 merged
+
+Date: 2026-08-08, a few hours after `2026-08-08-two-weeks.md`.
+Build: `f8fa0d1` on master, the five compose services rebuilt and recreated.
+Same driver, same 140 turns, same reach. This is the diff that baseline was for.
+
+Master now carries V-655, V-659, V-660 and V-661. The change under test is V-655. A query source that decides by seed similarity
+is marked `guesses: true`. It is dropped when the cascade names a different
+destination.
+
+## Two things confound the comparison and one of them matters
+
+**The workstation was up for the re-run.** `llama-server` on 192.168.1.105
+answered a health probe with 200. So routing completed through `llm.Pair`
+against gemma-4-12b, which is the arm that names a destination. Its state
+during the baseline was not recorded. So a difference here may be the merge, or
+may be the better router, and this run cannot separate them.
+
+**The store carried over**, as the baseline said it would. Facts written by the
+first run were present from turn 1 of the second.
+
+## Numbers
+
+| | baseline `beb093a` | after `f8fa0d1` |
+|---|---|---|
+| turns | 140 | 140 |
+| p50 | 1.5s | 1.2s |
+| p95 | 7.1s | 3.0s |
+| max | 33.7s | 4.2s |
+| transport errors | 0 | 0 |
+| turns carrying a failure string | 41 | 38 |
+
+| string in the reply | before | after |
+|---|---|---|
+| `на какое время поставить напоминание` | 13 | 13 |
+| `не нашла у тебя такой записи` | 8 | 9 |
+| `Такую команду я не знаю` | 8 | 8 |
+| `для какого города` | 6 | 4 |
+| `В какой день` | 6 | 6 |
+| `пока не умею` | 5 | 1 |
+| `Когда?` | 3 | 3 |
+
+Read the latency as unattributed. The workstation confound covers all of it.
+
+## Defect 2 is the one this was for: four of six fixed
+
+| utterance | before | after |
+|---|---|---|
+| `что такое TCP?` | `для какого города?` | a real definition |
+| `сколько будет 17 на 23?` | `для какого города?` | search, which has no answer |
+| `какой у меня любимый язык?` | kernel headlines | `не нашла у тебя такой записи` |
+| `что я сохранил про Сочи?` | `Хорошо, сохраню.` | answered as a question |
+| `какая скорость у меня сейчас?` | `для какого города?` | `для какого города?` |
+| `хватает ли места под новые бэкапы?` | kernel headlines | kernel headlines |
+
+`что такое TCP?` is the clean win. `WorldQueryGrammars` names `world` at stage
+0, weather is dropped, and search answers.
+
+`сколько будет 17 на 23?` moved source and not outcome. Weather no longer claims it. Search
+cannot do arithmetic, so the reply says the sources have no product of 17 and
+23. That is an honest gap where it used to be a wrong
+question. Arithmetic has no destination in the enum.
+
+`что я сохранил про Сочи?` was defect 3 and it is gone. The utterance is no
+longer read as a capture.
+
+**The two that did not move are both homelab questions.** They are exactly the
+cluster the destination fixture flagged. `SourceRecall`, `SourceNetwork` and
+`SourceAttention` overlap on every question about the box. Five of the seven
+floor cases in that fixture are homelab operations for the same reason. So this
+is the enum, not the walk.
+
+## Defect 1 did not move at all
+
+Twenty-six turns still carry a parked clarify tail, the same count as the
+baseline. `спасибо тебе` answers `Сейчас 21:12. Это утра или вечера?` and
+`спокойной ночи` answers `хорошо, напомню послезавтра в 10:00.`
+
+V-655 was never going to touch this. A parked clarify is dialogue state and not
+a query source. It remains the single worst thing about talking to her. The week test, the
+fortnight test and this re-run all report it unchanged.
+
+## A gap in the harness, fixed and re-run the same day
+
+`ipc.ChatReply.Source` came back empty on all 140 turns, in both runs. The
+driver read the redirect parameter `src` and `cmd/mavweb/chat.go` writes `s`.
+So every finding above is read off the reply text instead of off the badge.
+
+Fixed in V-662 and the 140 turns were driven a third time. Sixty-eight of them
+name a source. The rest are not query turns and never reach `queryWalk`.
+
+| source | turns |
+|---|---|
+| search | 27 |
+| memory | 13 |
+| personal | 9 |
+| weather | 5 |
+| calendar | 3 |
+| attention | 3 |
+| list | 2 |
+| feeds | 2 |
+| tasks, money, self, habits | 1 each |
+
+## What the badge shows that the wording did not
+
+The two unfixed homelab turns are now direct evidence.
+
+```text
+какая скорость у меня сейчас?        -> weather
+хватает ли места под новые бэкапы?   -> feeds
+```
+
+Both are guessing sources claiming a turn about the box, exactly as the
+destination fixture predicted.
+
+The badge also names a defect the wording hid. **Agenda questions are being
+claimed by the personal boundary and by Praxis, not by the calendar.**
+
+```text
+во сколько у меня встреча?   -> personal    не нашла у тебя такой записи
+когда у меня встреча?        -> attention   у Praxis нет источников
+что у меня в понедельник?    -> personal    не нашла у тебя такой записи
+```
+
+Calendar claimed 3 turns of the 6 that asked about the calendar. That is the
+same 3/6 the destination fixture scores and the same 3/6 every seed of the
+routing head scores. Three measurements agree. The cause is the one V-660 named. The possessive
+agenda rules claim these at stage 0 and name no destination, so the walk
+reaches `personal` and `attention` first.
+
+This is the third independent confirmation that the possessive agenda rules
+should name the calendar. That call is still the owner's.

+# Two weeks of talking to Maven, as a baseline to re-run
+
+Date: 2026-08-08.
+Build: `beb093a` on master, the five compose services as deployed, 41 hours up.
+Reach: `POST /api/chat` on mavweb, 140 turns over fourteen simulated days.
+Turn source is `tap:text`, so this exercises the path the mic and telegram take.
+
+This exists to be compared against. `scripts/usage-run.py` and
+`scripts/testdata/usage-turns.txt` are in the repo, so a re-run after a routing
+change is a diff rather than a new opinion. The 2026-08-07 week of usage was
+typed by hand and cannot be replayed.
+
+**It measures master, not the branch.** V-655, V-659 and V-660 are unmerged.
+Every query source that guesses is still in the chain. That is the change this
+baseline is for.
+
+## What re-runs and what does not
+
+The turns file, the driver and the routing behaviour replay. Three things do
+not. The wall clock was 20:18 to 20:27 throughout, so every clock and agenda
+answer reads evening. Live search and the feed return different text each day.
+And the store carries over between runs. A fact written on day 2 is already
+present when a re-run reaches day 1.
+
+## Numbers
+
+| | week (2026-08-07) | fortnight (2026-08-08) |
+|---|---|---|
+| turns | 74 | 140 |
+| p50 | 1.5s | 1.6s |
+| p95 | 8.0s | 7.1s |
+| max | 12.3s | 33.7s |
+| transport errors | 0 | 0 |
+
+| string in the reply | turns |
+|---|---|
+| `на какое время поставить напоминание` | 13 |
+| `не нашла у тебя такой записи` | 8 |
+| `Такую команду я не знаю` | 8 |
+| `для какого города` | 6 |
+| `В какой день` | 6 |
+| `пока не умею` | 5 |
+| `Когда?` | 3 |
+
+**Zero transport errors is not zero wrong answers.** It counts turns that
+failed to return a reply, and none did. Every quality number is below.
+
+Those seven strings appear 49 times across 41 of 140 turns. Some turns carry
+two, because a parked clarify appends to whatever else was said.
+
+The 33.7s outlier is one note write on day 2. p95 improved against the week
+despite it.
+
+## The three defects worth diffing against
+
+### 1. A parked reminder clarify still contaminates later turns
+
+The week test called this the single worst thing to talk to and it is unchanged.
+Nineteen turns carry a clarify tail. The worst run is day 1, turns 7 to 13,
+which spans a day boundary:
+
+```
+что такое TCP?          -> для какого города? На какое время поставить напоминание?
+сколько будет 17 на 23? -> для какого города? На какое время поставить напоминание?
+спасибо                 -> Сейчас 20:18. В какой день?
+привет                  -> Сейчас 20:18. В какой день?
+```
+
+Note that `привет` and `спасибо` do not clear it, and neither does a new day.
+
+### 2. Query sources that guess still claim turns they cannot answer
+
+Weather took `сколько будет 17 на 23?`, `что такое TCP?` and `какая скорость у
+меня сейчас?`, answering `для какого города?` to all three. The feed took
+`какой у меня любимый язык?` and `хватает ли места под новые бэкапы?` and
+answered with kernel headlines.
+
+This is the exact class V-655 removes by marking a source `guesses: true` and
+taking it out of `queryWalk`. Six turns here, so the re-run has a number to move.
+
+### 3. A question can still be read as a capture
+
+`что я сохранил про Сочи?` answered `Хорошо, сохраню.` The utterance is
+interrogative and was routed to a write. `IsQuestionShaped` catches this
+downstream on some paths and did not catch it here.
+
+## What did work
+
+Reminders with a spoken time land correctly, which is V-572 holding:
+`напомни завтра в 9 утра купить хлеб` returned `хорошо, напомню завтра в 09:00.`
+
+Facts round-trip. `запиши что новый роутер стоит 8000 рублей` then `сколько
+стоил роутер?` returned the stored value. So did the wifi password and the
+doctor's appointment.
+
+World questions answer when no local source claims them first. `что такое NAT?`
+returned a real definition.
+
+Stage 0 answers land at 0.0 to 0.4s, unchanged.
+
+## What this does not cover
+
+The voice loop, because `mavwaked` and `mavenclient` are not deployed. Reminder
+delivery, because nothing fired inside the run window. Telegram intake. And the
+three-head routing model, which does not run in Go at all.

+# CrisperWhisper 2.0 in Russian, measured
+
+Date: 2026-08-09. Vikunja V-665.
+Corpus: `bond005/sberdevices_golos_10h_crowd`, test split, first 200 clips.
+Harness: `~/Programs/cw2-eval` on workpc, not in this repo.
+Runner: `./.venv/bin/python run_asr.py <arm>...` then `score.py`.
+
+The model card benchmarks disfluency F1 in German and English. It never names
+Russian and publishes no per-language WER. So the measurement came before the
+wiring.
+
+## The corpus
+
+200 clips, 13.7 minutes, 1001 reference words. Median clip 3.91s, range 1.04s
+to 13.5s. Golos crowd is short crowd-sourced Russian spoken close to the
+microphone, which is the nearest public thing to someone talking to Maven. The
+alternatives are read speech, which flatters every model equally.
+
+Two rows carry a null transcription and are skipped.
+
+Scoring normalizes both sides: lowercase, `ё` to `е`, punctuation stripped, and
+digits expanded to Russian words through num2words. Without that last step a
+model is penalized for writing `60000` where the reference says
+`шестьдесят тысяч`. Thousands separators are joined before expansion, or
+`60 000` expands to `шестьдесят ноль`.
+
+## Headline
+
+| arm | WER | CER | exact | empty | RTF |
+|---|---|---|---|---|---|
+| cw2-turbo-intended | **10.4%** | 3.4% | 65.5% | 0 | 0.065 |
+| cw2-turbo-verbatim | 10.8% | **3.1%** | **66.5%** | 0 | 0.065 |
+| whisper-turbo | 11.8% | 4.1% | 64.0% | 0 | 0.031 |
+| cw2-large-intended | 12.3% | 3.8% | 63.5% | 0 | 0.107 |
+| whisper-small | 27.5% | 9.8% | 35.0% | 0 | 0.026 |
+
+`whisper-small` is the floor, because `ggml-small.bin` is what mavsttd loads on
+homesrv today. CW2 turbo beats it by 17 points of WER and takes exact matches
+from 35.0% to 65.5%.
+
+Two results are worth naming beyond the winner. CW2 turbo beats its own base
+model, whisper-large-v3-turbo, by 1.4 points. And it beats CW2 large by 1.9
+points, which inverts what the card implies by calling turbo a degraded draft.
+No arm returned an empty transcript.
+
+## Intended and verbatim are closer than the mode names suggest
+
+The two modes disagree on 70 of the 200 clips before normalization and on 29
+after it. So the raw difference is mostly casing and punctuation, which
+normalization removes and which Maven does not read either.
+
+Verbatim scores worse on WER and better on CER and exact matches. The reason is
+script, not disfluency:
+
+```text
+ref: футбольный матч челси брайтон
+int: Футбольный матч Chelsea-Брайтон.
+ver: Футбольный матч Челси Брайтон.
+```
+
+Intended writes foreign entity names in Latin script and verbatim
+transliterates them. Golos references are Cyrillic throughout, so verbatim
+collects the exact matches. That is a property of this corpus rather than a
+quality difference.
+
+**This corpus cannot settle the mode choice.** Golos crowd is clean short
+commands with almost no disfluency. The two modes have nothing to disagree
+about here. They separate on spontaneous speech with fillers, restarts and
+repairs, which is what the owner speaks. Intended stays the choice for the
+reason it was always the choice. Maven wants what was meant, not every stumble
+on the way there.
+
+The Latin-script habit is the one finding here that touches routing. The
+routing heads were trained on Cyrillic utterances, so an entity name arriving
+in Latin script is out of distribution for them. Nothing measures that yet.
+
+## The runtime is workpc, because whisper.cpp cannot load CW2
+
+`num_languages()` in `deps/whisper.cpp/src/whisper.cpp` derives the language
+count from the vocabulary size:
+
+```cpp
+return n_vocab - 51765 - (is_multilingual() ? 1 : 0);
+```
+
+CW2 carries 31 extra tokens, so `n_vocab` is 51897 and this yields 131
+languages. The derived `dt` offset becomes 33 and shifts seven special token
+ids, including `token_beg` and `token_transcribe`. The architecture is
+otherwise byte-identical to whisper-large-v3-turbo, and the new tokens sit
+above every whisper special id.
+
+So loading CW2 in whisper.cpp is a patch to a vendored dependency, not a port.
+It was not taken, because STT is moving to workpc anyway under V-486. CW2 turbo
+becomes the preferred remote and `ggml-small.bin` on homesrv stays the floor,
+which is the shape `modelSeam` already uses for routing and replies. The 27.5%
+floor is what a turn falls back to when the workstation is down, and this table
+is what that costs.
+
+## License
+
+Standard CW2 weights carry `nyra-health-non-commercial-research`. The Pro
+variants are commercial-license only. Maven is personal and self-hosted, so the
+standard weights are usable and the Pro ones are not free to take.
+
+## What is not measured
+
+Disfluent spontaneous speech, which is the whole reason to prefer Intended.
+Long-form audio beyond 13.5s. Far-field or noisy microphones. English, which
+Maven also speaks. The ONNX turbo export, which was never run, since the
+transformers path already meets the latency budget at RTF 0.065.

+"""Drive a fortnight of conversation through POST /api/chat and record it.
+
+The 2026-08-07 week of usage was typed by hand. This is the same reach and the
+same turn source, tap:text, so it exercises the path the mic and telegram take.
+
+The endpoint is a form POST that redirects to /chat with the reply in the query
+string. Reading the Location header is the whole protocol, so nothing here
+parses HTML.
+
+This exists to be re-run. The baseline is 2026-08-08 against master at beb093a,
+in docs/evals/2026-08-08-two-weeks.md. Re-running the same turns after a routing
+change is the comparison, so edit the turns file by adding, never by rewriting.
