WIP: BUG-5 slot-array fix + FEAT-1 dead-not-skipped + skip parser
WORK IN PROGRESS — fix not complete. analyze-turns.js on 500-round replay still finds 46 real skips + 64 double-acts. turn.js changes: - computeTurnOrderAfterAddition: insert by initiative (not append end) - nextTurn wrap: no re-sort, cycle pointer - togglePause resume: no re-sort, order stable - addParticipant: patches turnOrderIds when started - applyHpChange: death no longer flips isActive or touches turnOrderIds (FEAT-1 dead-not-skipped) Tests: - shared/tests/turn.skip.test.js (NEW): deterministic skip invariants pure 100 rounds + 540 rounds w/ mutations, both green - shared/tests/turn.dead-skip.test.js: 4 green (FEAT-1) - turn.characterization.test.js: 3 sites updated to new behavior - turn.combat.test.js: boundary count fixed (wrap-turn attributed to new round), debug dump removed scripts/analyze-turns.js (NEW): deterministic replay-stdout parser. Reconstructs rounds, reports real skips + double-acts. Exit 1 on issue. Catches bugs unit tests miss (46 skips/64 double-acts in 500 rounds). TODO: FEAT-1 marked done, FEAT-2 added (upgrade app logs parseable).

// scripts/analyze-turns.js

// Ingest replay-combat.js stdout (or any text matching its format), reconstruct
|
||||
// rounds, report real skips + double-acts. Deterministic — no eyeballing.
|
||||
//
|
||||
// Usage:
|
||||
// node scripts/analyze-turns.js [path] # analyze a saved log file
|
||||
// node scripts/replay-combat.js 100 100 | node scripts/analyze-turns.js
|
||||
// cat /tmp/replay.log | node scripts/analyze-turns.js
|
||||
//
|
||||
// Skip = participant active for WHOLE round (never deactivated/removed mid-round
|
||||
// before their slot, never added mid-round) but never appeared as a turn actor.
|
||||
// Double-act = same participant takes 2+ turns in one round.
|
||||
//
|
||||
// FEAT-2 (structured turn snapshot in app logs) will let this ingest live app
|
||||
// logs too, not just replay stdout. Format-agnostic core lives in parseReplay().
