- Buffer and publish observed upstream usage when apply patch transformation or translation encounters an error in Meta and xAI executors
- Add stream usage buffer helpers to report failure metrics with captured upstream token usage
Closes: #6427
- Add `PayloadFinalizer` to apply configuration rules at the final serialization barrier
- Support decoding, modifying, and re-encoding Devin protobuf business fields
- Add multipart form-data payload normalization to JSON for media payload rules
Closes: #5067
- Handle apply_patch custom tool call streaming deltas and snapshots for Responses API translation
- Track and resolve step indexes, function call identities, and error states across stream events
- Propagate apply_patch tool input errors and upstream failure states in stream and non-stream responses
- Restore client-defined `web_search` tool names from their alias across SSE, websocket, and buffered execution responses.
- Preserve namespaced tool calls when matching and restoring tool names.
Closes: #5923
- Initialize `util.SessionIDResolver` to resolve session IDs from request contexts, metadata, and headers.
- Ensure canonical session metadata is injected into execution options across execution flows.
- Propagate session context in executors to support `$CPA-SESSION-ID` expansion in custom headers.
- Sync cleared or updated session identities back to execution contexts during conductor execution.
Closes: #5690
- Introduce `xaiNamespaceRestorer` to track and restore folded dispatcher tool calls across SSE and WebSocket response events.
- Support unwrapping dispatcher tool calls and arguments in `output_item.added` and `function_call_arguments.done` events.
- Normalize historical input namespace tool calls to dispatcher format when namespace folding is active.
Closes: #5214
The xAI executor only switched on response.completed, so any turn that
ended with the spec-correct response.incomplete terminal event fell out
of the loop. Non-streaming requests were reported to the client as a 408
("stream disconnected before response.completed") even though the
upstream request succeeded, and because 408 is retryable it burned
credential rotations against a healthy pool. Streaming requests forwarded
the terminal event without patching the collected output items or
publishing usage.
Accept response.incomplete alongside response.completed in both paths,
mirroring the Codex executor, and keep the reasoning replay cache gated
on response.completed since a truncated turn has no replayable state.
- Propagate request headers into custom-header resolution for OpenAI/Gemini/XAI/Codex execution and websocket flows.
- Resolve auth `header:` values like `$ABC` from incoming request headers at request time and omit headers when no value is available.
- Add documentation for the dynamic custom-header behavior in `config.example.yaml`.
Closes: #5053
- Removed deprecated interceptor and executor-related methods, including `callRequestInterceptor`, `callResponseInterceptor`, and `callStreamChunkInterceptor`.
- Consolidated unused logic and pruned redundant imports to streamline `adapters.go`.
- No functional changes.
