+- Human: "do the next step" → fix phase (1) of the audit note, plan approved in chat; issue #362 reused (plan comment posted); Mind `active/timing_noise_audit_phase2_overhead_verdict.md` (3a3d4fc6); worktree `timing-noise-audit-p2-overhead-verdict`; Opus executes. The superseded Mind draft `call_accounting_ci_timing_threshold.md` ("increase it a bit so merge goes through") was retired on the human's approval — the guard is fixed, not relaxed.
+- Scope: one `abba_overhead_verdict` used by both the CI test and `fixed_light_numba.py`; budget 12 ms of excess over the clean call; one-sided small-sample t-interval of the excess vs budget → PASS / FAIL / FAIL_GROSS / INCONCLUSIVE; n < 3 and below-1 ratios INCONCLUSIVE; cell raises only on FAIL/FAIL_GROSS and keeps the JSON otherwise; promotion requires PASS; the test warns visibly on INCONCLUSIVE; the 1.031 ratio constant goes. No budget raised.
