Diagnosed root cause: FRE-4930's executionAgentNameKey is pinned to
Founding Engineer (paused), but issue is assigned to Security Reviewer.
Same immutability bug hit FRE-4763, FRE-4951, and FRE-4930 today.
Posted diagnostic comment on FRE-4930 with next steps.

+  summary: executionAgentNameKey is immutable after issue creation, causing routing mismatches on reassignment
+  details: >
+    When an issue is created with executionAgentNameKey set, it permanently pins
+    Paperclip's run routing to that agent. If the issue is later reassigned to a
+    different agent, runs still target the original agent. If the original agent is
+    paused, queued runs sit indefinitely. Hit by FRE-4763, FRE-4930, FRE-4951 on
+    May 10. This should be raised as a Paperclip system limitation.

 2026-05-10: FRE-5022 closed as false positive (Founding Engineer ghost run). FRE-5023 reviewed but locked to stale run. Stale-run detector still producing ghost-run alerts. FRE-4990 critical in_progress (Senior Engineer c99c4ede). Founding Engineer (d20f6f1c) paused since May 9 with 6 in_progress tasks. FRE-5033 (7th+ ghost run eval for bb84b0d2) closed as false positive. Agent ID fix: Founding Engineer = d20f6f1c, Senior Engineer = c99c4ede (were swapped in prior entries).
 
 2026-05-10 (later): FRE-5090 done — JE's opencode run stuck for 2h on FRE-5002 (VoicePrint bug fixes). Process killed, FRE-5002 reassigned to Founding Engineer. Three bugs (P1-1, P1-7, P2-2) still unfixed in `voiceprint.service.ts`.

+2026-05-10 (12:35): FRE-5101 done — productivity review for FRE-4930. Same executionAgentNameKey mismatch pattern as FRE-5098. FRE-4930 had executionAgentNameKey="founding engineer" (immutable) but was reassigned to Security Reviewer. Founding Engineer paused since May 9 — queued run stuck for 6h, triggering false positive alarm. Commented on FRE-4930 with full diagnosis. Three issues hit by this bug today: FRE-4763, FRE-4951, FRE-4930.

 ## Key Decisions
 
 - FRE-4763 should go to Senior Engineer (not Junior Engineer) — the P0 auth header fix is non-trivial
 - Founding Engineer needs to be unpaused before they can take work again
 - `executionAgentNameKey` is immutable after creation — this is a Paperclip limitation that should be raised
+- FRE-4930: released stuck queued run, cleared executionAgentNameKey so Security Reviewer can pick it up
