• 🟡 (13:04) Investigation inspected /home/byk/Code/opencode-lore-provider-error/packages/gateway/src/pipeline.ts lines 9258–9739, covering assertOutputLifecyclesComplete, assertTerminalOutputMatches, terminal response/output validation, keepalive and SSE frame handling, the finish(resp: GatewayResponse, successful: boolean): boolean implementation near line 9621, recall admission, abort handling, follow-up execution, and shiftedOutputIndex.
• 🟡 (13:05) Investigation inspected /home/byk/Code/opencode-lore-provider-error/packages/gateway/src/pipeline.ts lines 8562–9256, covering function-call identity reconciliation, reasoning/content lifecycle state, authoritative and final value checks, duplicate function-argument completion detection, response.output_item.done, seedImplicitCodexItem, terminal response identity/status validation, and malformed terminal-event errors.
• 🟡 (13:05) Search for provider failure behavior returned exactly 100 matches with additional results truncated. Matching test files included /home/byk/Code/opencode-lore-provider-error/packages/gateway/test/llm-adapter.test.ts, /home/byk/Code/opencode-lore-provider-error/packages/gateway/test/pipeline-streaming.test.ts, /home/byk/Code/opencode-lore-provider-error/packages/gateway/test/openai-responses-stream.test.ts, and /home/byk/Code/opencode-lore-provider-error/packages/gateway/test/openai-responses-recall-aware-stream.test.ts.
• 🟡 (13:05) Relevant failure-path coverage found in /home/byk/Code/opencode-lore-provider-error/packages/gateway/test/openai-responses-stream.test.ts includes sanitizing response.failed terminals with statuses failed and cancelled; rejecting inconsistent terminal combinations such as response.failed with completed or incomplete; preserving the public message "Gateway request failed"; logging "openai-responses provider failure"; Codex suppression versus public emission of response.failed; and the line 5400 test "emits response.failed and still calls onComplete (exactly once) when the upstream errors mid-stream".
• 🟡 (13:05) Relevant recall-aware failure-path coverage found in /home/byk/Code/opencode-lore-provider-error/packages/gateway/test/openai-responses-recall-aware-stream.test.ts includes PUBLIC_GATEWAY_ERROR = "Gateway request failed" at line 174; principal provider-failure sanitization; a line 739 test sanitizing a recall-bearing provider failure before later lifecycle checks; a line 829 test keeping created metadata authoritative through hidden recall and provider failure; and a line 905 test projecting trusted in-progress metadata before provider failure.
