 ## Confirmed bugs (tests written, NOT fixed)
 
 ### BUG-1: addParticipant + pause/resume corrupts turn rotation
+- **RESOLVED** as side effect of BUG-2 fix (dup-id rejection broke chain).
+- Audit: 0 violations / 100 rounds after BUG-2 fix.
+- Replay: 10 rounds clean, no skip/dupe.
 - Audit: 128 violations / 100 rounds, 4 symptom faces.
 - Symptom chain (one bug family):
   1. pause blocks nextTurn advance → totalTurns stays frozen (e.g. 120)

 ### BUG-2: addParticipant allows duplicate id
-- `addParticipant(enc, dup)` appends same id to participants[] twice.
-- togglePause resume rebuilds order → id appears twice in turnOrderIds →
-  nextTurn stuck repeating that id.
-- Reachable in normal app? App uses crypto.randomUUID (fresh ids) so
-  unlikely. But no guard exists — defensive bug.
+- **FIXED** (commit: addParticipant throws on dup id).
 - Test: `shared/tests/turn.characterization.test.js` 'addParticipant rejects
-  duplicate id' — test.skip currently (validates current allow-dup behavior).
+  duplicate id' — GREEN.
 
 ## Pipeline
 - [ ] Red test: dead participant still in turnOrderIds, turn still advances to them
