{"repo":"NousResearch/hermes-agent","public_id":"110849","display_label":"PTY session reaping blocked by attach/socket errors","summary":"Several fixes address scenarios where erroring or dropped WebSocket attachments leave PTY sessions permanently marked as attached, preventing idle reaping from reclaiming them. The changes cover socket send errors, mid-replay drops, and commit-ordering issues in the attach lifecycle — including a case where `PtySession.attach()` commits attached state before the replay write, leaving the PTY permanently unreapable if a client drops during attach.","subsystem":"dashboard","counts":{"members":5,"open_issues":0,"open_issues_distinct":0,"open_prs":2,"closed_issues":1,"merged_prs":1,"attempt_prs":3},"landed_fix":{"status":"merged_to_main","basis":"structural","pr":111357,"merged_at":"2026-09-15T13:36:21+00:00"},"resolution":{"state":"resolved","by":"pr-111357"},"freshness":{"state":"verified","last_verified_at":"2026-09-15T13:36:21+00:00","is_stale":false},"grouping":{"backbone":"STRUCTURAL_SPANNING","link_density":0.4},"fix_edges":[{"issue_number":110849,"pr_number":111357,"tier":"verified","basis":"closing_ref","confidence":0.95,"recoverable_from_timeline":true,"pr_merged_at":"2026-09-15T13:36:21+00:00"}],"members":[{"kind":"issue","number":110849,"title":"PtySession.attach() commits attached state before the replay write — a client dropping during attach leaves the PTY permanently unreapable","url":null,"state":"closed"},{"kind":"pr","number":110859,"title":"fix(pty): recover sessions after socket send failures","url":null,"state":"closed","close_reason":{"refs":[{"kind":"pr","value":"#111357","number":111357}],"category":"superseded_by_pr","implication":"superseded"},"merged":false},{"kind":"pr","number":110861,"title":"fix(dashboard): roll back a mid-replay attach drop so idle reaping can reclaim the PTY","url":null,"state":"open","close_reason":{"refs":[{"kind":"pr","value":"#111357","number":111357},{"kind":"pr","value":"#110849","number":110849}],"category":"implemented_elsewhere","implication":"superseded"},"merged":false},{"kind":"pr","number":110863,"title":"fix(pty): make failed websocket attachments reapable","url":null,"state":"open","close_reason":{"refs":[{"kind":"pr","value":"#110849","number":110849},{"kind":"pr","value":"#110859","number":110859},{"kind":"pr","value":"#110861","number":110861}],"category":"superseded_by_pr","implication":"superseded"},"merged":false},{"kind":"pr","number":111357,"title":"fix(dashboard): dropped terminal viewers no longer pin the PTY as attached forever (#110849, salvage #110859)","url":null,"state":"merged","close_reason":{"category":"merged"},"merged":true,"is_fix_pr":true,"fix_tier":"verified","files_changed":["hermes_cli/pty_session.py","hermes_cli/web_routers/chat_ws.py","tests/hermes_cli/test_pty_session.py"]}],"trust":{"default_tier":"verified","includes_suggested":false}}
