Restack onto mainNew SHA: Conflicts resolved (all in code touching the timeout-deadline work from #1053, which landed on main after this branch forked):
Tests
Readiness reviewThe delta does what the title says: it closes consumed HTTP error/stream responses (chat, raw, binary, synthesis paths) after classification and before retry/backoff, while preserving the caller-owned raw-error handoff and the tool-execution-stopped/response-limit contracts. No defects found in the merged result; the merge itself required interleaving this PR's cleanup logic with main's independently-landed deadline/timeout enforcement (#1053), which is now exercised together (bounded read + per-chunk deadline + close-on-consume). Notes from the PR's own description (not new findings, just flagging what's still open going in): the PR is explicit that no live-load resource or latency gain has been measured, the full strict suite (warnings-as-errors) is still RED at the frozen candidate (unrelated pre-existing failures per its runbook), and a separate trace-fixture leak ( Verdict: READY_CANDIDATE for the restack (merge clean, targeted tests green, 100% docstring coverage). Overall PR readiness for merge still depends on the hosted gates, independent approval, and protected-merge/full-suite evidence the description itself calls out as outstanding — deferring to the maintainer on when those are satisfied. 🤖 Addressed by Claude Code |
Preserve HTTP response lifecycle ownership from #1140 while keeping main's cache/batch/workflow guidance and updated timeout diagnosis. Co-authored-by: Cursor <cursoragent@cursor.com>

In `@contextual_orchestrator/orchestrator.py`:
- Around line 3701-3712: Update proxy_completion to close each retained
urllib.error.HTTPError before switching candidates, and ensure the finally
cleanup also closes the stored error on final classification and
request-size-limit paths. Reuse the existing HTTPError check and close handling
around last_error, preserving the primary failure and avoiding duplicate or
unrelated exception changes.
In `@docs/doctoring/http_test_resource_lifecycle.md`:
- Line 197: Update the reproduction command in the documented test instructions
to use the project-relative, configurable PYTHON default instead of the personal
absolute interpreter path, while preserving the existing pytest arguments and
test files. Keep the separate absolute path at the earlier evidence entry
unchanged.
In `@docs/product-technical-gap-baseline.md`:
- Line 917: Restore the missing newline between the preceding sentence ending
with “CI gate or a test of the released fast-mlsirm implementation.” and the
heading “## 2026-09-12 timeout owner reconciliation and unknown-outcome safety”
so the heading renders correctly.

proxy_completion에서 전달받은 HTTPError를 명시적으로 닫으십시오.
proxy_send_once는 _proxy_send(..., allow_transient_retries=False)를 호출합니다. _send_raw_with_retry는 이 경로에서 원시 HTTPError의 소유권을 호출자에게 넘기고 자체적으로 닫지 않습니다. proxy_completion은 재시도 가능한 HTTPError를 last_failure에 저장한 뒤 후보를 전환하지만, 이전 예외나 최종 예외를 닫지 않습니다. classify_provider_failure는 safe_provider_message로 응답 본문을 읽을 뿐 HTTPError.close()를 호출하지 않습니다.
후보 전환 전에 기존 last_failure의 HTTPError를 닫으십시오. 최종 분류 경로와 요청 크기 초과 경로도 finally에서 보관 중인 HTTPError를 닫도록 처리하십시오. 그렇지 않으면 실패가 반복될 때 응답 리소스가 즉시 정리되지 않아 가용성이 저하될 수 있습니다.

Parent and scope
Stacked on #1135 exact c7ed393. Candidate head eeed2d9. The parent remains the transport single writer; no existing PR was edited or closed. Test cleanup a1ce38ee is fully cherry-picked as 87dcc53, followed by production fix 712ab29 and evidence documentation. The parent contains the same streaming method AST, limit expression and test delta as #1128, but full succession of all predecessor PRs must be independently verified before any closure.
Change
Close HTTPError responses after classification, including terminal tool-stop paths. Cleanup exceptions cannot replace the safe primary error. Preserve parent response-limit passthrough and existing error ordering. Close test-owned sockets and error bodies; no warning suppression, model timeout, retry policy or numerical routing change.
Verification
Remaining gates
Full-suite, installed package at this head, hosted checks, independent approval and protected merge remain outstanding. No release/deployment or actual accuracy/latency gain claimed. The coordinator reported central CodeQL #6957 credential failure separately; this source change neither repairs nor bypasses central credentials, and its status must be checked with the central owner. No paid model fallback or gate weakening.
See docs/doctoring/http_test_resource_lifecycle.md and docs/product-technical-gap-baseline.md for lineage, commands, failed attempts and limits.
