Kev's call: the 30D accuracy surfaces must read TRUTH, not a cache that can't be filtered. My earlier degraded-row exclusion only touched getModelAggregate (Postgres); the public buckets/badge still read outcomeService (Redis outcome log), which counts degraded projection-0 outcomes and has no field to filter on. - /api/accuracy (AccuracyBadge) + /api/ledger/accuracy (buckets/ModelRecord) now source from the clean Postgres ledger aggregate via new ledgerService.getAccuracyView + accuracyBucketsFromAgg (model_value > 0 excludes degraded rows). Same response shapes → no frontend change. Redis outcome log is now read by nothing public; it can age out or be rebuilt. - BEAT CLOSE is a MEASURED-WRONG ZERO: captureClosing re-records the locked line as the "closing" line, so clv is flat on the whole sample and beat_close reads 0% (comparing a number to itself). Full write-up: specs/audit-data/ clv-capture-broken.md (the fix belongs to C4). Until then, beat_close_pct + clv_distribution are SUPPRESSED at the source (getModelAggregate, gated by clvCaptureReliable() / CLV_CAPTURE_RELIABLE=1). Every public surface already renders BEAT CLOSE only when non-null, so they all hide it now — no wrong zero anywhere. HIT RATE (real) is unaffected. Suite 271/3261 green, web build exit 0.
