A pick-up-later index of work orders — each item points at its spec and carries a worktree name, a paste-ready dispatch line, and parallel-conflict flags (the sim.rs/save.rs contention that decides what can run at once). check.sh skips it (an index, not a system spec); README points to it. Defense: the constitution rule — agents should build the game from the documents alone; this is the index that turns 'split it into agents' into a mechanical, low-collision operation. No game behavior change.
