Nightly self-improvement · slate 2026-09-07

Generated 2026-09-08T05:00:00.005655-04:00 ET from official finals (mlb-api). Every learning stage is listed with what it did. "Blocked" means it wanted to act and a safety rule stopped it; "nothing to learn" means it had no eligible evidence.

Luna KPI candidates and their promotion gate

Promotion needs 400+ prospective rows over 5+ slates after the proposal, with a gain interval above zero. Only verified pregame forecasts count; local replays never do.

Luna post-mortem

Luna (gpt-5.6-luna) post-mortem, status received. Full analysis.

# 1. Evidence receipt and gaps

## Sources received

All seven `source_manifest` entries were checked against the supplied evidence:

| Source | Status | Purpose |
|---|---:|---|
| `prediction_review_20260907.json` | Loaded | Official outcomes and scoring errors |
| `PREDICTION_SYSTEM_DEEP_AUDIT_20260907.json` | Loaded | Probability, provenance, starter, and decision contracts |
| `continuous_learning_daily_20260907.json` | Loaded | Pipeline-stage quality, calibration, probability lineage, score distribution, and starter comparisons |
| `detailed_20260907.html` | Loaded | Full game and simulation rendering |
| `20260907_ultra_detailed_player_audit.html` | Loaded | Player-level prediction trace |
| `audit_report_20260907.html` | Loaded | Invariant findings |
| `audit_report_20260907_integrity_revision.html` | **Missing** | Post-Luna remediation proof for immutable revision artifacts |

The missing integrity-revision audit is the only explicitly missing source. It prevents independent confirmation of immutable revision-artifact remediation, although the supplied structural and per-game audits report no critical or error findings.

## Slate coverage

All 11 expected games were reviewed:

`ARI@KC`, `ATL@PHI`, `CHC@MIL`, `CIN@LAD`, `CLE@BAL`, `LAA@BOS`, `MIN@DET`, `NYM@MIA`, `STL@SF`, `TOR@OAK`, and `WAS@SD`.

Coverage is internally complete for the principal slate artifacts:

- 11 expected games
