f9475e9739Phase A.3 of the rule-variants epic — preset-controlled turn flip gating. Enables double-move (white plays 2, then black plays 2) and monster (scope-aware: white plays 2, black plays 1) without engine changes at the preset layer. - Adds HalfMovesThisTurn: number to ChessAttrMap. Seeded to 0 in applyLayout. Distinct from HalfmoveClock (FIDE 50-move rule) — this counter is within-turn and resets on flip. - Adds TurnAdvanceContext + shouldAdvanceTurn hook to PresetDef. Hook receives post-increment count via ctx.halfMovesThisTurn so 'play N half-moves before flipping' reads as the predicate 'halfMovesThisTurn < N -> false'. - engine.applyMove: increments HalfMovesThisTurn BEFORE polling shouldAdvanceTurn; first false wins; on flip resets to 0 and increments FullmoveNumber after black; onTurnStart is gated on shouldAdvance (vetoed flips don't fire turn-start hooks, so mid-turn stamina regen bugs are prevented by construction). - starting-position.test.ts updated with HalfMovesThisTurn=0 seed assertion. - New turn-advance.test.ts (7 tests): seeding, baseline unchanged, never-flip veto, flip-after-two (double-move surface), onTurnStart gating across vetoed + non-vetoed flips, FullmoveNumber increments only on actual flips after black. Tests: 1441 passing (was 1434, +7 new). Blocks: unblocks B.2 (double-move), B.3 (monster-rules), B.4 (first-promotion-wins). |
