- move root floors.json into packages-user/data-state/test/fixtures/ (byte-identical) and delete the root copy
- add saveablesReal.perf.ts: toFlat/clearCodes/registerTiles/createRealMapFixture with a one-shot compareWith baseline
- seed the minimum 1 equipment instance so HeroEquipsStore.loadState does not raise error 58
- 3 rows: save / load / round trip for 1 map x NoCompression, zero assertions
- rewrite every built-in as EventXxx implements BuiltInFunction<P, E>
(setBlock/moveBlock/deleteBlock/moveHero/moveHeroStep/touchFront/
insertEvents/insertEvent), matching the EventSetBlock reference style
- move shared helpers to event/utils.ts (getPossibleMap, getPossibleLayer,
getEventExecutor, enter/exitEventInsert); utils is not exported via index
- move per-class helpers into private methods (EventTouchFront and
EventInsertEvents collectInvocations)
- use IObjectMover.push for move sequences instead of manual step calls
- registrations.ts: one createEventRegistrations() writing the eight entries
in order, categories separated by single-line comments
- remove EventBuiltinName; classes own short string names
- update event tests; core.ts uses createEventRegistrations
- Load the fixed replay event through the internal serialized boundary
- Assert trigger, raw statements, coordinate binding, one execution, and final state
- Extend the closed-loop fixture across hero and all map matrices
- Throw deterministic local diagnostics at the first replay divergence
- Add the dedicated test:data-node process gate
