Merge branch 'worktree-agent-a0ab2a9b7439296e3' into overnight-jul31

Chose an 8th enum value over a confidence number: the model already picks
one enum token, so it costs nothing in the grammar, while a score from a
0.8B model would be uncalibrated noise. A refusal returns "no decision"
with no error, which is the fall-through the caller already uses for a
bad parse, so the classifier and its clarify gate take the turn.

Reviewers: the prompt's counter-examples matter most — a small model will
over-use any easy escape hatch. The training workspace copy of the prompt
still needs the same edit (Vikunja #362).

 Never compare a hash-embedder run to an ONNX one.
 
+## Re-measured after the prompt fix
+
+The table above is the **baseline at commit `46259b4`**, kept as-is. The prompt fix (query
+tested before fact, plus `repeat_penalty` and a bounded grammar string) was then measured on
+an otherwise idle box — no other eval sharing llama-server, so these latencies are real
+rather than contention.
+
+| | llm-only (0.8B) | cascade+llm (0.8B) | llm-only, thinking off |
+|---|---|---|---|
+| **intent-only accuracy** | 48.7% → **61.8%** | 50.0% → **63.2%** | **67.1%** |
+| full accuracy (intent+slots+gate) | 23.7% → **38.2%** | 32.9% → **47.4%** | **42.1%** |
+| route errors | 2 → **0** | 0 → 0 | **0** |
+| p50 / p95 latency | **1.08s / 1.55s** | **1.04s / 1.53s** | **0.93s / 1.41s** |
+
+Three things this run settles:
+
+1. **The prompt fix holds.** An earlier contended run reported 60.5% / 36.8% for llm-only;
+   the quiet run gives 61.8% / 38.2%. Close enough to call the gain real, and the earlier
+   run's 4-5s latency figures were contention, not the model.
+2. **`query→fact` fell from ×15 to ×7**, and both unparseable replies are gone. Zero route
+   errors in every LLM configuration.
+3. **`note→fact ×4` is real, not noise.** It shows up in the quiet run too. The agent that
+   wrote the prompt fix suspected its own change might have caused it by pulling assertive
+   `запиши что…` phrasings toward fact, and that suspicion stands — all five `ru-note-*`
+   cases now land on fact. Tracked as Vikunja #375.
+
+**Thinking off is the best configuration measured so far**, on both accuracy and latency
+(Vikunja #376). That is worth understanding before flipping: routing is a short
+classification into a fixed enum with grammar-constrained output, so there is little to
+reason about, and the thinking trace mostly gives a small model room to talk itself out of
+the right answer. Phrasing is a different job and needs measuring separately.
+
+Still `6 / 6` missed clarify — the router has no way to say "I don't know" (Vikunja #359).
+That is unchanged by anything here.
+
