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 Both hits PROVES are withdrawn: they were drawn through that reader, and defense_by_direction's distinct-n was likely below the gate floor all along.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 Both verdicts stay withdrawn. 4,772 tests / 371 suites green, web build exit 0, read-integrity harness 34/34.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> |

runs + RBI: mostly-base-rate confirmed, and one level deeper than expected
Nothing proved. For RBI even the ARCHETYPE split is theatre, so the honest grade is the POOLED base rate. PREMISE NOTE: the order's closing line says the batter board is per-archetype-graded after this. Nothing has been rescaled for hits or total_bases either -- no archetype slot has ever reached sample and gradeBands remains built, gated and unwired. This is the fourth stat measured, not the completion of three. AUDIT: RBI 935 clean / 43 games; RUNS 617 clean / 33 games. Zero quarantined. No archetype slot reaches 500 -- and the signature archetypes the order names are the two SMALLEST slots on the board, RBI->DRIVER at n=24 and runs->CATALYST at n=9. RUNS is refused structurally before any factor is tested: 33 game clusters against a 40 floor. INPUTS RECONSTRUCTED rather than declared missing. lineup_context only covers 08-04 onward while settled rows start 07-31, so 187/617 runs rows joined. But the play-by-play cache runs from 05-01 and the batting order IS the order batters first appear -- slot, power-behind and reach-base all rebuilt point-in-time, coverage 187 -> 574. RBI, all THEATER: risp_opportunity +0.0047, extra_base_skill +0.0010, risp x extra_base +0.0056. RUNS, all refused on clusters and all pointing the wrong way: +0.0043 / +0.0008 / +0.0054. THE COMPOUND IS THE WORST VERSION IN BOTH STATS. The causally-correct compound was the most promising factor on the sheet and is the most harmful in each. Two multipliers that individually carry nothing do not cancel -- they compound each other's noise. Distinct from the collapsed-sequence lesson: there the product of two REAL effects was too small to use; here the product of two NULL effects is worse than either. THE ARCHETYPE DOES NOT RESCUE IT, and this is where the session nearly went wrong. The base rates look strongly differentiated (RBI DRIVER 0.609 vs BOMBER 0.413; runs GHOST 0.716 vs BOMBER 0.460). Gated directly against the pooled base rate: RBI +0.0010 CI [-0.0034,+0.0050] THEATER; runs -0.0028 CI [-0.0147,+0.0108] candidate at k=33. DRIVER's 0.609 is n=23 -- small-slot noise wearing a decimal point. Read off the table instead of gated, this would have shipped as "archetype differentiation is real and large". It is not. THE CROSS-STAT PATTERN THAT IS REAL -- the counter over-predicts every batter counting stat measured: total_bases p_win 0.5698 vs actual 0.5074 bias +0.0624 rbi p_win 0.4860 vs actual 0.4313 bias +0.0547 runs p_win 0.5949 vs actual 0.5749 bias +0.0200 Across four stats and three sessions, calibration is the systematic defect and factor scarcity is not. TB's held-out isotonic fix (-0.0039) still outperforms every factor tried on any stat, all null or theatre. NO RESCALE. Nothing proved, nothing certified calibrated, no slot at sample, and for RBI the archetype split is itself theatre -- so the honest band is the pooled base rate, which gradeBands 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 |
