Merge master after 199-201 landed (V-661)

CLAUDE.md said naming SourceWorld leaves his notes, his facts and the
personal boundary running first. The first two are true and the third is
not. The boundary is marked guesses: true, so queryWalk drops it whenever
the named destination is not recall.

That is deliberate and tested. It is what stops the boundary answering
'кто такой Линус Торвальдс?' with 'не нашла у тебя такой записи'. But it
means a destination a model wrote can take the boundary off a turn about
him, and the doc claimed the opposite.

Flagged as the owner's call rather than changed. Only the utterance leaves
the box either way.

+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.

+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

+
+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

+`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,

+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

+# 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.

+V-659 measured the destination at 12/33 on the classifier cascade, with recall

+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

+
+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.

+
+Data is `amazon-massive-dataset-1.1` pulled from S3. The Hugging Face repo is

+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 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`,
+`train_heads.py`, `score_confidence.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.
+
+| body | floor corpus | intent mean | destination mean |
+|---|---|---|---|
+| warm-started `out/body_massive` | one shape | 93.6% | 75.8% |
+| 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.

+# 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) |

+
+**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 in 49 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.
