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.

+by the other's traffic. Measured on 2026-08-08: one question about a reminder's
+day rode turns 7 to 13. It ended only because turn 14 was a new request.
+
+`PendingQuestion.Rides` counts the same event as `Suspends` with the resets

+# 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.

+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.

+# 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.
