[Gastown] Update: patrol triage role mismatch loop is unfixable from mayor side + self-feeding on escalations

[kilo-code-bot]

What happened?

Update to already filed issue #4147

Adding new evidence and one critical constraint discovered: Kilo Gastown provides no mechanism for the mayor or user to add a triage role to an agent or configure the rig's agent roster. The mayor's toolset (gt_agent_reset, gt_bead_update, gt_bead_reassign, etc.) has no triage-role provisioning. Therefore the only fix must be platform-side.

Additional evidence (past ~8 hours)

• Escalations now self-feed: failed triage batch → escalation bead → patrol creates another triage batch for the escalation → another failure → another escalation
• Affected every polecat in the rig: Toast, Maple, Birch, Clover, Ember, Shadow, Sage
• Patrol batch titles observed: "Triage batch: N request(s)", "Cannot resolve triage requests", "Role mismatch preventing triage request resolution"
• Mayor cannot silence the patrol without a platform patch
• Bulk-deleting failed beads repeatedly did not stop the loop; it regenerated within minutes

Observed escalation messages

• Triage agent role mismatch blocking all triage request resolutions
• Cannot resolve triage requests: API 403 errors blocking all resolutions
• Cannot resolve GUPP force-stop triage: role mismatch blocking resolution
• Triage agent cannot resolve requests due to permissions
• Unable to resolve triage batch — agent lacks triage permissions
• Polecat role lacks triage resolution permissions

Suggested fixes

1. Patrol should check for a triage-role agent before dispatching a triage-request bead
2. Patrol should back off exponentially after repeated 403 failures in a rig
3. Better: auto-provision one triage-role agent per rig when the rig is created
