The fix tracks commit fences as a registration stack to keep the correct fence live when compression attempts overlap.","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":117558,"merged_at":"2026-09-20T22:27:12+00:00"},"resolution":{"state":"resolved","by":"pr-117558"},"freshness":{"state":"verified","last_verified_at":"2026-09-20T22:27:12+00:00","is_stale":false},"grouping":{"backbone":"STRUCTURAL_SPANNING","link_density":0.6666666666666666},"fix_edges":[{"issue_number":116635,"pr_number":117558,"tier":"verified","basis":"closing_ref","confidence":0.95,"recoverable_from_timeline":true,"pr_merged_at":"2026-09-20T22:27:12+00:00"}],"members":[{"kind":"issue","number":116635,"title":"Out-of-order completion of overlapping _compress_context calls corrupts the commit-fence slot","url":null,"state":"closed"},{"kind":"pr","number":116640,"title":"fix(compression): track commit fences as a registration stack","url":null,"state":"closed","close_reason":{"refs":[{"kind":"commit","value":"09b72bc6d2","number":0},{"kind":"pr","value":"#117558","number":117558}],"category":"merged_via","implication":"superseded"},"merged":false},{"kind":"pr","number":117558,"title":"fix(compression): overlapping compression attempts keep the newer attempt's commit fence live (#116635, salvage #116640)","url":null,"state":"merged","close_reason":{"category":"merged"},"merged":true,"is_fix_pr":true,"fix_tier":"verified","files_changed":["agent/compression_facade.py","tests/agent/test_compression_commit_fence_race.py"]}],"trust":{"default_tier":"verified","includes_suggested":false}}
