CI-02 preview state

Chess Insights Preview

Deterministic CI-01 pilot results (fast-12 / pilot-40) from the frozen sanitized corpus. This is a dev-preview of aggregate metrics for an external test player — not your account and not a stable player trait. Preview policy gaps are shown below.

What do these numbers mean?
  • M03 — critical moment accuracy: share of critical decisions where an acceptable move was played. numerator / denominator = acceptable decisions / all critical decisions. Higher is better.
  • M04 — repeat error rate: repeated error series by theme (fork, pin, loose piece, …). 0 means the detector found no sufficient series yet — product decision pending.
  • confidence: tentative = minimum sample (20+ decisions across 5+ games), stable = robust sample (50+ across 15+ games).
  • source sha256: checksum of the frozen aggregate report; mismatches fail closed (503).
  • Where the data comes from: CI-01 pilot on the frozen external public test corpus — 1,000 finished standard games, snapshot 2026-08-12, corpus SHA-256 fff09343… — analyzed with Stockfish 18 at depth 18 / MultiPV 5. Sanitized aggregates only; the player is an external_public_test subject, not a PoodleChess account.
