Corrected audit summary

Current Data Set

The system now separates missing payout data from verified no-pool refunds. A missing payout parse is marked UNGRADED_MISSING_PAYOUT, not treated as a returned stake. The active dashboard namespace is corrected_scenarios, leaving the old scenario files available for comparison.

What Was Fixed

Payout Coverage Audit

The main data-quality problem is show-pool coverage. The current result set has 1,967 show-pool rows with missing or unverified show payout data, only 120 show-pool rows with complete payout data, and 31 rows where no wagering/no pool is verified.

Corrected Strategy Results

Resolved ROI is the primary metric only when coverage and sample size are adequate. Show-based strategies still have poor coverage unless they are explicitly restricted to the 120 complete show-payout rows. No strategy passes the validation rule set.

Old vs Corrected

The old show-only dashboard showed 2,086 show bets, $41,750 wagered, $40,531.20 returned, and -2.92% raw ROI because 1,966 rows were treated as no-pool refunds. The corrected run keeps those 1,966 rows as UNGRADED_MISSING_PAYOUT. Only 120 show bets are actually resolved, and those resolved bets are -40.63% ROI.

The old 70% show limit had the same issue: 779 of 837 rows were missing payout rows, not verified no-pool refunds. Its corrected resolved sample is only 58 bets at -45.30% ROI. The complete-data show baseline isolates the 120 verified complete show-payout rows and confirms the same -40.63% resolved ROI.

Validation Finding

No corrected strategy is actually profitable under the corrected grading and walk-forward validation rules. Several strategies are also proxy-only because this data set has morning-line or estimated prices, not true live tote snapshots.

Phase 2 Forensic Findings

The current model beats random on win hit rate, but it does not beat the morning-line favorite. That means strategy tuning should stay disabled until the model, probability calibration, and source coverage improve.

Question Answer Evidence
Does model rank beat random?Yes on win hit rateModel rank #1 win hit rate 28.66% vs random 15.35%.
Does model rank beat morning-line favorite?NoMorning-line favorite win hit rate 32.65% vs model rank #1 at 28.66%.
Does model rank beat final public favorite?Insufficient final-odds coverageOnly 2.4% of races have parsed final-odds favorite coverage, so this is diagnostic-only and not reliable.
Are odds parsed correctly?Unit tests passEVEN, 5/2, 8/5, 110, favorite markers, and missing odds are covered.
Are program number and post position separated?Yes, with audit warnings14,926 entries checked; 4,221 program/post differences are listed for audit, not collapsed into one field.
Can show-payout coverage be repaired now?No alternate files foundTrackMaster adapter dry-run found 0 vendor files and 0 repair candidates for 1,967 missing show-payout races.
Which strategies remain candidates?None0 strategies pass validation; live-wagerable strategy count is 0.

Phase 3 Findings

Phase 3 fixed parser-audit semantics and rebuilt model diagnostics around the morning-line baseline. Candidate strategy count remains 0; live-wagerable strategy count remains 0.
