 ## Sanity-check the data first
 
 Before judging performance, verify the measurement is sound:
-- `python -m pytest sim/ -q` green? (The trace checksums are pinned there — a failing checksum means someone moved the ruler.)
+- `python -m pytest sim/ -q` green? (The trace checksums are pinned there; a failing checksum means someone moved the ruler.)
 - Do the numbers parse and look sane (n matches the trace, error_rate in [0,1], no inf where successes exist)?
-- In doubt, run `bash tools/metric-contract.sh` — numeric, deterministic, separating.
+- In doubt, run `bash tools/metric-contract.sh` (numeric, deterministic, separating).

 ## What to output (structured)
 
 - **Metrics**: mean effective latency, p95, error rate on train; the champion config.
 - **Data health**: tests green, checksums intact, contract status if run.
 - **Verdict**: one of `improving` | `flat` | `degrading` | `insufficient_data`, judged against LOG.md history. Justify with the numbers.
-- **Diagnosis**: WHY — where the remaining effective-latency mass sits (errors? slow-episode waits? retry overhead?). Quote numbers.
-- **Top problem**: the single biggest cost right now — floor breach always outranks latency.
-- **Recommended focus**: ONE knob from the declared budget, stated as a hypothesis — the mechanism, the traffic regime it assumes, and the metric it should move.

 - Is the gain concentrated in a handful of requests (a lone spike, not a ramp)? Check the dumped vectors, not just the means.
 - Is the candidate inside the declared 24-config budget? An out-of-budget candidate is not certifiable this campaign.
 
 ## Hard rules (auto-reject if violated)
 
-1. Traces mutated or regenerated, or scoring changed in the same iteration as a policy change — automatic reject, no reconsideration.
-2. Any floor breach (`error_rate > 2%` on either window) — automatic reject. A latency win bought with errors is a regression.
-3. Any binding verdict.py outcome violated (step 2 REJECT, step 3 REJECT, step 4 PROMOTE) — reject.
