Each got the same + one-paragraph stamp: surface-class identification + provenance-vs- + policy distinction + carve-out citation. Discipline reads as one-line + answer to recurring concern. + +2. **Stale-resolved-by-reality at ~54% on this PR.** 7 of 13 total + threads (10 first-wave + 3 second-wave) were "doc claims X, but X + is actually true now per Otto-114 forward-mirror" or "fix already + landed in a downstream commit." The reply pattern is verify-with- + evidence + resolve, not re-fix. + +3. **Codex-as-mathematics-reviewer on canonical definitions.** The DORA + P1 finding on L285 caught a real correctness issue on a benchmark + doc — the prior wording would have skewed Stage-2 measurements under + different batch sizes. This is the same shape as the K-relations + retraction-limitation finding on #206 (semirings-vs-rings precision + error) — Codex catches subset-vs-superset framing errors reliably. + +## Final resolution + +All 13 threads resolved (10 first-wave merged at SHA `fbd9284`, then +3 second-wave at `bccfd2b` — one Codex P1 plus two Copilot P2).
