refactor: 1-list turn order model (turnOrderIds === participants.map(id))
Single source of truth. No re-sort after startEncounter. Drag overrides
initiative (cross-init drag allowed, DM choice). Display === rotation by
construction — same array.
shared/turn.js:
- syncTurnOrder(participants) helper: turnOrderIds = participants.map(id)
- startEncounter: sort ALL participants by init (active+inactive), inactive
stay in slot, nextTurn skips them. currentTurn = first active.
- addParticipant: splice into participants[] by init pos, sync turnOrderIds.
computeTurnOrderAfterAddition returns insertAt (caller splices + syncs).
- removeParticipant: filter participants[], sync turnOrderIds, advance
current if removed==current.
- toggleParticipantActive: stay in slot (flip isActive only), sync. Advance
current only if deact hits current.
- reorderParticipants: cross-init drag allowed (remove same-init restriction).
Splice participants[], sync turnOrderIds. Fixes BUG-6.
- computeTurnOrderAfterRemoval: only handles current-advance now (list sync
at call site).
Tests updated to 1-list contract:
- turn.invariant.test.js: 10 tests, turnOrderIds===participants.map(id)
always, cross-init drag, inactive-in-slot, rotation follows list.
- turn.characterization/reorder/round-rotation/undo/remove: updated
expectations (inactive-in-slot, cross-init drag, turnOrderIds sync on
reorder, insertAt return).
Results: shared 90 green. 500-round replay CLEAN (0 skips, 0 doubles,
0 order shifts). BUG-6 (reorder divergence) fixed structurally.
FE App.js still has duplicate turn funcs + sortParticipantsByInitiative
display render (step 4: delete dups, render participants[] directly).
