Merge the thinking-off measurement

The 67.1% "thinking off" column in ROUTING-EVAL-31-07-2026.md was an
artefact. It came from a hand-rolled HTTP client in the eval test that
did not send repeat_penalty, so it differed from the reference run on two
axes and the penalty was the one that mattered.

Re-scored back to back on an idle box with everything else held equal:
thinking off is identical to thinking on, case for case, same confusion
matrix, same three unparseable replies. A direct probe of the running
llama-server shows enable_thinking, thinking and reasoning_budget are all
ignored for this model on this build, so there was nothing to turn off.

No defaults changed. The misleading third configuration is removed from
internal/router/eval so its table cannot be quoted again.

+The `thinking off` column above read as the best configuration measured so far (Vikunja #376).
+**It was wrong** — see the controlled re-run below. Ignore that column.
 
 Still `6 / 6` missed clarify — the router has no way to say "I don't know" (Vikunja #359).
 That is unchanged by anything here.
 
+## Thinking off — 31-07-2026, controlled re-run (Vikunja #376)
+
+The "thinking off wins by 6 points" observation above **does not hold**. It was a measurement
+artefact, and the earlier table's `thinking off` column should be ignored.
+
+The thinking-off variant was scored by a hand-rolled HTTP client living in the test file
+instead of `llm.Client`. That copy did not send `repeat_penalty`, which the real router does
+send (`routeRepeatPenalty = 1.15`). So the two columns differed on two axes at once, and the
+one that mattered was the penalty, not the thinking mode.
+
+Re-measured with everything else held equal — same fixture, same prompt, same grammar, same
+sampling, same idle box, the three configurations run back to back and never concurrently:
+
+| | llm-only, thinking on | llm-only, thinking off | cascade+llm |
+|---|---|---|---|
+| intent-only accuracy | 59.2% (45/76) | 59.2% (45/76) | 61.8% (47/76) |
+| full accuracy (intent+slots+gate) | 38.2% (29/76) | 38.2% (29/76) | 57.9% (44/76) |
+| route errors | 3 | 3 | 0 |
+| grammar violations | 3 (all 3 route errors) | 3 (same 3 cases) | 0 |
+| missed clarify | 5 / 6 | 5 / 6 | 5 / 6 |
+| p50 latency | 836ms | 920ms | 810ms |
+| p95 latency | 1.41s | 2.00s | 1.31s |
+
+Thinking off is not just a tie on the headline numbers — it is identical case for case, with
+the same confusion matrix and the same three unparseable replies. The latency difference is
+run-to-run noise on one box, and it points the wrong way here.
+
+The reason is simpler than any accuracy argument: **this llama-server build ignores the
+request-level thinking switch for this model.** Probed directly against the running server
+with `chat_template_kwargs.enable_thinking = false`, `chat_template_kwargs.thinking = false`
+and top-level `reasoning_budget = 0` — all three return a byte-identical answer with the
+thinking trace still in `reasoning_content`, and the server reports the prompt prefix as
+cached, meaning the rendered template did not change. There was never anything being turned
+off, which is also why the numbers match exactly.
+
+Nothing was defaulted. `internal/llm` still has no `chat_template_kwargs` field, `VoiceConfig`
+has no thinking flag, and `deploy/mavend.json` is unchanged. The misleading third
+configuration is removed from `internal/router/eval` so the table it produced cannot be quoted
+again.
+
+Two caveats worth saying out loud:
+
+- **The fixture is 76 cases.** A 6-point difference on 76 cases is roughly 4-5 cases and would
+  not have been worth trusting even if it had reproduced. This one was exactly 0 cases, which
+  is a much easier call.
+- **This is one server build and one checkpoint** (`b9351`, Qwen3.5-0.8B Q4_K_M). If the
+  #122 checkpoint or a newer llama.cpp does honour the switch, the question reopens — but it
+  reopens as an unmeasured question, not as a 6-point win.
+
+Phrasing was **not** measured. Whether thinking helps there is still open, and now also blocked
+on the same "can we even turn it off" question.

 ### 7. Two hypotheses tested and closed
 
-- **Thinking mode is a non-issue.** Qwen3.5's template defaults `thinking = 1`, so
-  grammar-constrained JSON lands in `reasoning_content` with `content` empty —
-  `llm.Client`'s fallback handles it. A `thinking off` run scored *identically* (18/76,
-  48.7%, same p50). `internal/llm` deliberately does **not** grow a `chat_template_kwargs`

+- **Thinking mode is a non-issue.** Confirmed twice now, the second time properly — see the
+  controlled re-run section. Grammar-constrained JSON lands in `reasoning_content` with

+  nothing on this build. `internal/llm` deliberately does **not** grow a

 - **Runaway array repetition does not reproduce.** An isolated smoke test with a stripped
   grammar emitted `{"intent":"reminder"}` until `MaxTokens`; under the real `routeSystem`
   prompt the few-shot examples anchor it to one object. 2 errors in 76, not 76.
