Via subagent, verified against real behavior (all use jotai store + enableMapSet):
- state/list (11): createListAtom PUT/DELETE/REPLACE (single + array, identity).
- state/room/roomToParents (10): INITIALIZE/PUT/DELETE incl. cycle-skip and
orphan-cleanup pruning of zero-parent children.
- state/room/roomToUnread (22): unreadInfoToUnread, unreadEqual, and the
roomToUnreadAtom reducer — leaf/overwrite/equal-guard, multi-level parent
roll-up with `from` recording, RESET rebuild, DELETE subtract/prune.
No bugs (noted a latent never-hit string-spread in deleteUnreadInfo's `from ??
roomId` fallback; left as-is). Suite growing toward full pure-logic coverage.
