The proposed fix reads the command line via psutil first.","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":117562,"merged_at":"2026-09-20T22:25:47+00:00"},"resolution":{"state":"resolved","by":"pr-117562"},"freshness":{"state":"verified","last_verified_at":"2026-09-20T22:25:47+00:00","is_stale":false},"grouping":{"backbone":"STRUCTURAL_SPANNING","link_density":0.6666666666666666},"fix_edges":[{"issue_number":117270,"pr_number":117562,"tier":"verified","basis":"closing_ref","confidence":0.95,"recoverable_from_timeline":true,"pr_merged_at":"2026-09-20T22:25:47+00:00"}],"members":[{"kind":"issue","number":117270,"title":"[Perf]: the gateway-identity check forks `ps` on macOS when psutil (a core dependency) answers 190x faster","url":null,"state":"closed"},{"kind":"pr","number":117271,"title":"perf(gateway): read a PID's command line with psutil before forking ps","url":null,"state":"closed","close_reason":{"refs":[{"kind":"commit","value":"b93d68e424","number":0},{"kind":"pr","value":"#117562","number":117562}],"category":"merged_via","implication":"superseded"},"merged":false},{"kind":"pr","number":117562,"title":"perf(gateway): the identity check reads a PID's command line with psutil before forking ps (#117270, salvage #117271)","url":null,"state":"merged","close_reason":{"category":"merged"},"merged":true,"is_fix_pr":true,"fix_tier":"verified","files_changed":["gateway/status.py","tests/gateway/test_process_cmdline_source.py"]}],"trust":{"default_tier":"verified","includes_suggested":false}}
