Raw Normal View History

CB-WP-0033: a game is the unit make trials reported "positions unreachable: 4, target 0 — the recording exists but the position moved". All four were false. A recording holds one hash, the final state, and reachability asked whether the note's hash was in that file — so a mid-game note could never match, and a post-game note from any but the last game could not either. Instance 8 of the ADR-0018 family: vary only WHEN a note was written and the answer flips, with nothing having moved. The root cause was not the metric. play again reused state belonging to a game: it overwrote the previous game's recording (data loss), never cleared the journal (game 2's log opened with game 1's commands), and so a note's command index pointed into a recording without those commands. Fixing reachability alone would have gone green while a session still destroyed its own evidence. A note now binds by (game, after) — an index into the recording's own commands list, which a reader can replay to. The hash keeps a job as the integrity check at the end of a game, where it can actually fail. Game 1 keeps the path it was given, so GameDesign §5's documented invocation is unchanged; later games get -2, -3 and nothing is overwritten. Legacy 5-column logs stay readable and are reported as legacy, never as orphans — an unsubstantiated orphan claim is the defect being fixed. All three fixes mutation-proven, including at the call site via a real two-game session. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
