The fixes make the rollback logic handle the absent row without raising.","subsystem":null,"counts":{"members":5,"open_issues":0,"open_issues_distinct":0,"open_prs":0,"closed_issues":1,"merged_prs":1,"attempt_prs":3},"landed_fix":{"status":"merged_to_main","basis":"structural","pr":106522},"resolution":{"state":"resolved","by":"pr-106522"},"freshness":{"state":"verified","last_verified_at":"2026-09-09T16:21:40+00:00","is_stale":false},"grouping":{"backbone":"STRUCTURAL_SPANNING","link_density":0.4},"fix_edges":[{"issue_number":106271,"pr_number":106522,"tier":"verified","basis":"closing_ref","confidence":0.95,"recoverable_from_timeline":true}],"members":[{"kind":"issue","number":106271,"title":"Compression failure-cooldown rollback raises instead of tolerating a missing session row (turn-dispatcher crash)","url":null,"state":"closed"},{"kind":"pr","number":106276,"title":"fix(state): tolerate a vanished session row in compression cooldown rollback","url":null,"state":"closed","close_reason":{"refs":[{"kind":"commit","value":"8a50413ba2329e5182a97b68c69c9a703ad29ecb","number":0},{"kind":"pr","value":"#106522","number":106522},{"kind":"pr","value":"#106271","number":106271}],"category":"merged_via","implication":"superseded"},"merged":false},{"kind":"pr","number":106277,"title":"fix(compression): tolerate deleted cooldown sessions","url":null,"state":"closed","close_reason":{"refs":[{"kind":"commit","value":"8a50413ba2329e5182a97b68c69c9a703ad29ecb","number":0},{"kind":"commit","value":"17fe7bc75f7","number":0},{"kind":"pr","value":"#106522","number":106522},{"kind":"pr","value":"#106271","number":106271}],"category":"merged_via","implication":"superseded"},"merged":false},{"kind":"pr","number":106278,"title":"fix(state): tolerate missing session row in compression cooldown rollback (#106271)","url":null,"state":"closed","close_reason":{"refs":[{"kind":"pr","value":"#106276","number":106276}],"category":"superseded_by_pr","implication":"superseded"},"merged":false},{"kind":"pr","number":106522,"title":"fix(state): compression cooldown rollback no longer crashes the turn when the session row vanished (#106271, salvage #106276)","url":null,"state":"merged","close_reason":{"category":"merged","implication":"superseded"},"merged":true,"is_fix_pr":true,"fix_tier":"verified","files_changed":["hermes_state_compression.py","tests/agent/test_compression_concurrent_fork.py"]}],"trust":{"default_tier":"verified","includes_suggested":false}}
