synthesis is disabled when provider.authMode is "forward" by passing stateless
&& !forward. Add a regression test covering forward authentication combined with
statelessResponses.

Therefore, a forward-authenticated request can still run orphan-item repair, but it cannot receive a synthesized placeholder output unless its provider is also explicitly stateless.
The stateless tests also cover all required call types and preserve the existing orphan-output conversion behavior. If you found this review helpful, would you consider giving us a shout-out on X? Thank you for using CodeRabbit! You are interacting with an AI system. |
… tool calls DeepSeek's official Responses route is stateless and strictly validates that every function_call/local_shell_call/custom_tool_call has a matching output item in the same body. A Codex thread can reach that state when an interrupted tool turn records the call but not its late-arriving result, and the upstream then rejects every retry with a 'No tool output found for tool call' error, making the thread non-continuable. repairOrphanedInputItems already repaired orphaned outputs (output without call); extend it to synthesize an honest placeholder output immediately after each orphaned call, gated to stateless wires (forward replay keeps the prior fail-closed behavior). Mirrors the openai-chat adapter's flushPendingToolCalls wording so the model sees execution status is unknown, not a fabricated result.
…alls Address the CodeRabbit merge-risk note by adding explicit regression coverage that forward-authenticated replay does NOT synthesize placeholder outputs for orphaned calls: the repair is gated on statelessResponses, and these tests pin the unchanged forward wire.
…r synthesis CodeRabbit flagged that a provider configured with both authMode=forward and statelessResponses could receive synthesized placeholder tool outputs. Tighten the gate to stateless && !forward and add a regression test pinning that forward auth plus statelessResponses still forwards a dangling call unchanged.

Summary
DeepSeek's official Responses route is stateless and strictly validates that every
function_call/local_shell_call/custom_tool_callhas a matching output item in the same body. A Codex thread can reach that state when an interrupted tool turn records the call but not its late-arriving result; the upstream then rejects every retry withNo tool output found for tool call <call_id>, making the thread non-continuable (observed withdeepseek/deepseek-v4-flash; the same thread resumed fine on BLSC, which is tolerant).repairOrphanedInputItemsalready repaired orphaned outputs (output without call -> converted to a user message). This PR adds the mirrored repair: on stateless, non-forward Responses wires only, a call without its paired output gets an honest placeholderfunction_call_output/custom_tool_call_outputinserted immediately after it, mirroring theopenai-chatadapter'sflushPendingToolCallswording so the model sees the execution status is unknown rather than a fabricated result. Forward-mode replay keeps the prior fail-closed behavior.Verification
