+### BUG-13: reorderParticipants crossing current pointer = ambiguous acted-semantics
+- Discovered 7/1 replay. `reorderParticipants` (shared/turn.js:522) = pure
+  drag, no pointer logic. Swapping two actors across current pointer mid-round
+  = ambiguous who-acted-this-round. Earlier replay arbitrary swaps showed
+  skip/double (R9 Summon3 2x, R11 Goblin1 2x) before fix restricted swaps to
+  upcoming-only.
+- Replay now avoids crossing (adjacent upcoming pair only, commit af165f4).
+  Real app untested: if DM drags actor past current pointer mid-round, skip/
+  double behavior undefined.
+- Decide: block cross-pointer reorder, or define acted-semantics. RED needed.
+
+### BUG-14: addParticipant init-insertion breaks after drag-reorder
+- Discovered 7/1 replay. `computeTurnOrderAfterAddition` scans for first id
+  with init < addedInit, assumes list init-sorted. After drag, list NOT sorted
+  → scan hits wrong slot.
+- Trace turn 30→31: list `[Goblin1:20,Goblin2:22,...]` (drag moved Goblin1
+  before Goblin2). Add Reinforce3 init 21 → scan hits Goblin1:20 (idx 0, <21)
+  first → insert at 0. Should slot after Goblin2:22. WRONG.
+- Root conflict: 1-list model = drag source of truth (no re-sort); addParticipant
+  = init-based insertion (needs sorted list). After ANY drag, add-insertion
+  meaningless.
+- Proposed fix: append to end always (option A). DM drags to position. Matches
+  drag = source of truth. Makes `computeTurnOrderAfterAddition` trivial.
+- Related: FEAT-3 (initiative first-class field).
