The fix ensures such undelivered empty streams are retried rather than passed through as empty turns.","subsystem":"agent","counts":{"members":4,"open_issues":0,"open_issues_distinct":0,"open_prs":1,"closed_issues":1,"merged_prs":1,"attempt_prs":2},"landed_fix":{"status":"merged_to_main","basis":"structural","pr":113135,"merged_at":"2026-09-17T00:08:03+00:00"},"resolution":{"state":"resolved","by":"pr-113135"},"freshness":{"state":"verified","last_verified_at":"2026-09-17T00:08:03+00:00","is_stale":false},"grouping":{"backbone":"STRUCTURAL_SPANNING","link_density":0.5},"fix_edges":[{"issue_number":112419,"pr_number":113135,"tier":"verified","basis":"closing_ref","confidence":0.95,"recoverable_from_timeline":true,"pr_merged_at":"2026-09-17T00:08:03+00:00"}],"members":[{"kind":"issue","number":112419,"title":"[Bug]: Empty partial-stream stub (0 chars recovered) lets the turn continue as if nothing happened — model repeats the lost action","url":null,"state":"closed"},{"kind":"pr","number":112421,"title":"fix(agent): re-evaluate empty partial streams","url":null,"state":"closed","close_reason":{"refs":[{"kind":"pr","value":"#113135","number":113135},{"kind":"pr","value":"#112421","number":112421}],"category":"partial_fix","implication":"needs_llm"},"merged":false},{"kind":"pr","number":112513,"title":"fix(agent): retry undelivered empty partial streams","url":null,"state":"open","close_reason":{"refs":[{"kind":"pr","value":"#113135","number":113135}],"category":"superseded_by_pr","implication":"superseded"},"merged":false},{"kind":"pr","number":113135,"title":"fix(streaming): a stream that dies before any visible text is retried, not turned into an empty step the model repeats (#112419, supersedes #112513, #112421)","url":null,"state":"merged","close_reason":{"category":"merged"},"merged":true,"is_fix_pr":true,"fix_tier":"verified","files_changed":["agent/chat_completion_helpers.py","tests/agent/test_direct_contexts_stream_inline.py","tests/agent/test_request_client_reuse_abort_races.py","tests/agent/test_streaming.py"]}],"trust":{"default_tier":"verified","includes_suggested":false}}
