Read integrity, as-of context, and the shadow matchup resolve (A1-A7)
Seven orders of measurement-first repair. The served grade does not move. A0/A1 — the unordered page walk returned the right COUNT and the wrong ROWS: 410-617 of 2,490 duplicated with an equal number never returned, while rows.length matched the server exactly. safePaginate orders on a real unique key, verifies the tuple at runtime, and THROWS on a query error instead of treating it as end-of-data. Both hits PROVES are withdrawn: they were drawn through that reader, and defense_by_direction's distinct-n was likely below the gate floor all along. A2/A2b — rolled across every reader: 11 FAIL -> 0. Composite keys pulled from pg_index (the context tables are dated-composite and had no single unique column). The unordered helper is deleted, not parked. A3 — ledgerService and retentionService defaulted the SAME env var to DIFFERENT versions, so no ledger row ever carried the marker eligibility requires. One source now. model_snapshots settlement moved onto the cron: 15,484 -> 28,894 settled, repaired-champion 0 -> 7,556. A4 — hitsFactorContext takes an as-of cutoff. Refusal over reconstruction: no row at-or-before the date means the factor does not apply, never the nearest row. Live path unchanged, proven 400/400 on real rows. A5 — factor_inputs freezes what the factor READ, never the multiplier, so an audit can recompute and check. It also recorded the finding: the three hits factors have NEVER fired. prop.opponent and prop.opposing_pitcher are read by the resolver and written by nothing. A6/A7 — matchupKeys resolves those keys from the posted lineup plus the schedule's probable pitchers, and fires the factors into a SHADOW freeze: 248 fires on 308 props, 245 of which would move the grade. The served forecast is untouched. specs/a8-shadow-factor-gate.md pre-registers the test that decides whether they ever go live. Nothing is turned on. CALIBRATION_DEPLOYED stays []. Both verdicts stay withdrawn. 4,772 tests / 371 suites green, web build exit 0, read-integrity harness 34/34. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> |

total_bases: every power factor is THEATER, and a units bug nearly hid it
PREMISE CORRECTION: the per-archetype rescale is not "proven and live on hits". gradeBands was built, gated and explicitly NOT wired two orders ago -- no hits archetype slot reached sample, every band came back base-rate, and only defense_by_direction proved pooled. This applies an unvalidated-at-archetype-level method to a second stat. FULL-HISTORY AUDIT: 988 clean settled TB rows (101 quarantined, 948 with p_win), 341 players, and only 9 DISTINCT GAME DATES. No archetype slot reaches 500 -- BOMBER 340, GHOST 147, BRUSH 55. Confirmed short on full history, not a windowed artifact. The 9-date figure matters more than the row count: ~49 games means any game- or venue-borne factor has almost no replication here. THE BASELINE HAD TO CHANGE, to a harder null. TB lines vary (1.5 on 559 rows, 0.5 on 345), so a per-line personal base rate would rest on ~2 rows per player-line and would have to be invented. The null is the counter's own p_win, which already prices the line -- beating the champion, not beating "he's due". THE UNITS BUG, caught, and it had produced the best result in the programme. The first run reported barrel_rate at Brier -0.0095, the largest improvement ever measured here. fromStatcastRow returns barrel_pct as a FRACTION (0.06) while the raw table stores 0-100, so (0.06 - 7.8) * 0.018 clamped EVERY row to the maximum negative shift. That uniform downward push "improved" Brier purely by leaning on the counter's over-prediction and contained no barrel information at all. Same family as the S80 trap, inverted. exit_velo was a second bug -- the column is avg_exit_velo, so it read null on every row and reported n=0. A zero is a wiring bug until proven an honest absence. GATE with units fixed, 138 cumulative tests: barrel_rate n=707 shift 0.0364 brier +0.0036 THEATER exit_velo n=707 shift 0.0229 brier +0.0022 THEATER hard_contact_allowed n=707 shift 0.0260 brier +0.0033 THEATER park_weather_hit_type n=651 36 entities PENDING (k<40) platoon_severity n=481 PENDING (n<500) THE PREDICTED INVERSION WENT THE OTHER WAY. BOMBER x barrel_rate is +0.0114, the single most harmful cell in the table, exactly where the strongest proof was predicted. GHOST +0.0012. All sample-blocked so not a verdict, but recorded so it is not claimed later. AND IT IS NOT DOUBLE-COUNTING -- tested and refuted: corr(barrel, p_win) = -0.061, the counter is not pricing barrel at all. The duller answer is corr(barrel, counter RESIDUAL) = -0.012. Barrel is a real skill that carries no information about what the counter gets wrong at this line. That also closes the S81 lead: hard_hit r=0.153 at n=295 drifted to 0.135 at n=383 and is THEATER at n=707. THE REAL FINDING: TB is miscalibrated, not under-factored. mean p_win 0.5698 vs actual 0.5074, bias +0.0624. Held out on a strict time split (fit < 2026-08-02, eval 651 unseen rows): raw 0.25007, constant de-bias 0.24740 (-0.00267), isotonic 0.24621 (-0.00386). Worth more than any factor tested and the only intervention pointing the right way -- and still refused at the corrected bar on 32 clusters. A CANDIDATE, not a result. It also explains the units bug's fake success exactly: a blanket downward shift is a crude de-bias. NO RESCALE. Nothing proved, nothing certified calibrated, no slot at sample -- every band would be the honest base-rate band gradeBands already returns by construction. Counter and frozen clusters byte-identical. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01W1sivYNqY2TS5ftykmHBU9 |
