One report documents a severe real-world consequence: a wait loop for background subagents ran to the iteration ceiling, wasting 190 calls over 84 minutes before human intervention.","subsystem":null,"counts":{"members":3,"open_issues":0,"open_issues_distinct":0,"open_prs":0,"closed_issues":1,"merged_prs":1,"attempt_prs":1},"landed_fix":{"status":"merged_to_main","basis":"structural","pr":124724,"merged_at":"2026-09-27T18:20:29+00:00"},"resolution":{"state":"resolved","by":"pr-124724"},"freshness":{"state":"verified","last_verified_at":"2026-09-27T18:20:29+00:00","is_stale":false},"grouping":{"backbone":"STRUCTURAL_SPANNING","link_density":0.6666666666666666},"fix_edges":[{"issue_number":124072,"pr_number":124724,"tier":"verified","basis":"closing_ref","confidence":0.95,"recoverable_from_timeline":true,"pr_merged_at":"2026-09-27T18:20:29+00:00"}],"members":[{"kind":"issue","number":124072,"title":"[Bug]: Waiting on background subagents can deadlock a turn — execute_code-only wait loop ran to the iteration ceiling with zero guard activity (84 min, 190 wasted calls, human abort)","url":null,"state":"closed"},{"kind":"pr","number":124276,"title":"fix(agent): ignore volatile execution metadata in tool-result loop hash","url":null,"state":"closed","close_reason":{"category":"superseded_by_pr","implication":"superseded"},"merged":false},{"kind":"pr","number":124724,"title":"fix(agent): ignore execute_code per-call metadata in the loop-detector result hash","url":null,"state":"merged","close_reason":{"category":"merged"},"merged":true,"is_fix_pr":true,"fix_tier":"verified","files_changed":["agent/tool_guardrails.py","contributors/emails/[redacted:email]","tests/agent/test_tool_guardrails.py"]}],"trust":{"default_tier":"verified","includes_suggested":false}}
