From 8ae71a46b6b258c51ffefd14beb3cd2ddfd20abd Mon Sep 17 00:00:00 2001 From: Garry Tan Date: Sun, 17 May 2026 16:40:11 -0700 Subject: [PATCH] =?UTF-8?q?doctor:=204=20calibration=20checks=20=E2=80=94?= =?UTF-8?q?=20abandoned/freshness/drift/voice=20(T12)?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Adds the four calibration doctor checks per the eng-review spec. abandoned_threads: Counts active high-conviction takes (weight >= 0.7) older than 12 months that have never been superseded. Signal, not error — always status='ok' with a count. The hint sends users to `gbrain calibration` for details. calibration_freshness: Warns when the active profile is older than 7 days (configurable via the same env-var pattern other freshness checks use). Cold-brain branch (no profile yet) returns ok without scolding. Hint points at `gbrain calibration --regenerate`. grade_confidence_drift (CDX-11 mitigation): Surfaces the count of auto-applied grade verdicts. Below 30: returns "need 30+ for drift detection". At/above 30: returns "drift math arrives in v0.37+". The surface is wired; the actual confidence-vs-accuracy correlation math is a v0.37+ follow-up once we have 30+ auto-applied verdicts to measure against. Closes the CDX-11 hole structurally — the operator sees the surface even before the math is meaningful. voice_gate_health: Tracks voice gate failure rate over the last 7 days. <30% fail rate → ok (template fallback is fine in isolation). >=30% → warn with hint to review src/core/calibration/voice-gate.ts rubric. Anchors the cross-cutting voice rule observability story. All four checks return status='warn' with a diagnostic message on engine errors — non-blocking, never throws. Matches the existing doctor check pattern (see checkSyncFreshness for prior art). Wired into runDoctor after checkRerankerHealth (the v0.35 cluster), in the canonical block 10 slot. Tests: 15 cases. 4 per check (happy path, alt-status, engine-throw diagnostic, plus boundary tests for the freshness staleness gate at exactly 7 days and the grade drift gate at 30 applied verdicts).
