- CLAUDE.md: phase line moved to "Phase 1 deployed"; key files lists
the new bot module, game-end extraction, and selfplay harness.
- DECISIONS.md: new "Phase 1 implementation outcomes" subsection records
the CasualBrain-engine reversal, the FEN-vanilla-only invariant, why
blind keeps heuristic, and the bot-slot token randomization. The
earlier "Stockfish deferred" entry is partially superseded.
- .claude/handoffs/: handoff document for the next session.
