7531-7552: 🎯 Functional Correctness | 🔵 Trivial | ⚡ Quick winMigrate the
response.failedbranch of_stream_event_error_envelopeto the shared error parser.This function still parses a nested
response.failederror withOpenAIErrorEnvelopeModel.model_validate({"error": error_value})directly. SinceOpenAIError.paramisStrictStr | None, a malformed (present, non-string)paramvalue raisesValidationErrorhere, and theexceptbranch replaces the whole error with_default_error_envelope(). This discards the realerror.codeanderror.message, not just the param.
_collect_responses_payload's identicalresponse.failedbranch was migrated in this PR (Line 8070) to use_parse_event_error_envelope, which goes through_parse_openai_errorand correctly falls back to manually reconstructing the error fields while preservingcode/message/typewhenparamis malformed._stream_event_error_envelopeis used by_probe_stream_startup_errorfor startup-error classification, so this gap can silently replace a real upstream failure code with a genericupstream_errorduring startup probing when the upstream sends a malformedparam.Use
_parse_event_error_envelope({"error": error_value})here for consistency with the rest of this PR's error-handling migration.♻️ Proposed fix
- if isinstance(error_value, dict): - try: - return OpenAIErrorEnvelopeModel.model_validate({"error": error_value}) - except ValidationError: - return _default_error_envelope() + if isinstance(error_value, dict): + return _parse_event_error_envelope({"error": error_value})🤖 Prompt for AI Agents

The loop reports only the first failing case and hides which input failed. Lines 38-39 also recompute the expected values with the same rule the parser uses, so a regression in the normalization rule would change both sides together.

- Around line 188-212: Update the claim flow around claim_generation and
asyncio.wait_for so a timeout or cancellation after the durable
admission_generation update is reconciled using a claim token or equivalent
idempotent result. Resolve whether the claim succeeded before returning False,
while preserving failure handling for claims that genuinely did not commit.
In `@app/modules/proxy/_service/http_bridge/streaming.py`:
- Around line 3465-3475: Update reset_previous_response_recovery_operation_spool
so a failed reset returns without raising when required=False, while preserving
the existing error for required resets. Move the best-effort call for
recovery_path == "local_previous_response_error" to the branch handling the
failed session, before session is rebound, and remove the post-replacement call
so the operation is matched to its owning session.
In
`@openspec/changes/recover-codex-ws-stale-anchor-with-canonical-code/specs/responses-api-compat/spec.md`:
- Line 74: Define the same-owner replay admission rule, including how it durably

owner-bound and account-neutral scenarios to apply the corresponding
admission-generation behavior consistently with tasks 7.1–7.3.
In
`@openspec/changes/recover-codex-ws-stale-anchor-with-canonical-code/split-plan.md`:
- Around line 43-50: Update the PR 2 “Primary files/hunks” list in split-plan.md
to include the migration file, app/db/models.py, and
tests/integration/test_migrations.py alongside the existing circuit-generation
changes.
In `@tests/integration/test_proxy_websocket_responses.py`:
- Around line 6179-6208: Update
test_v1_responses_websocket_masks_invalid_request_previous_response_not_found_without_retry
to parametrize the upstream error code alongside param and cover both canonical
previous_response_not_found and non-canonical invalid_request_error shapes with
param="previous_response_id"; rename the test to reflect both cases and keep the
existing malformed-parameter coverage.

Inline comments:
In `@app/modules/proxy/_service/http_bridge/upstream_events.py`:
- Around line 2032-2037: Update the grouped error classification around
is_previous_response_not_found_event and
is_previous_response_not_found_matching_event so the documented
invalid_request_error with the Invalid previous_response_id envelope is
classified as "previous_response_not_found". Reserve
PREVIOUS_RESPONSE_MALFORMED_PARAM_REASON for genuinely present malformed
parameters, preserving recovery and reconnect handling for valid stale-anchor
errors.
In `@app/modules/proxy/api.py`:
- Around line 8727-8750: The stale-anchor rewrite for top-level error events
must only occur when enforce_openai_sdk_contract is enabled; preserve the
original Codex-native error event when it is disabled. Update the event handling
around _is_previous_response_not_found_public_error and add a regression test
covering a top-level error with code previous_response_not_found under both
enforcement settings.

Problem
Under concurrent and multi-agent load, a Responses request can reuse a stale

Scope
This is a partial fix for the continuity failures tracked by #1529 and #1816;
it does not claim to close either issue wholesale. The exact reviewed head was
built and deployed locally as the Docker Desktop candidate documented below;
that local deployment is operational evidence, not upstream merge approval.
Candidate and review status

That exceeds the repository's large-PR guideline for multiple concerns; maintainer
acceptance or splitting remains required. OpenSpec build, copied-data rehearsal, and local redeployment evidence now exist.
Longer-running recurrence evidence remains observational and does not block review.

Merge gates still outstanding

all 41 threads are resolved, exact-head tests are green, and the local build,
rehearsal, and redeployment evidence is recorded above.
