Warn about vectors written before the marker existed

The embedder moved from paraphrase-multilingual-MiniLM-L12-v2 to
multilingual-e5-small. Both are 384-dimensional, so nothing in the code
noticed: cosine between an old stored vector and a new query vector is
noise, and recall degrades silently.

So the DB now records the embedder that wrote its vectors. One value for
the whole DB (migration #11, a small `meta` key/value table) rather than a
column on every vector row: the backfill re-embeds every note and fact in
one pass, so a per-row marker would hold the same string in every row and
cost a column on two tables for nothing.

The identity comes from the embedder itself via a new optional ID() method
("multilingual-e5-small@384", model file name plus dimension), so pointing
the config at another model changes the string without anyone editing a
constant. mavend logs a loud WARNING at startup naming both the stored and
the configured embedder when they differ.

Detection only — recall behaviour is unchanged. TODO(#378) in
store.CheckEmbedder marks where the backfill will hook in.

 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.
+
