fix: bound /parse request body before multipart parsing

[seonghobae]

현재 상태

/parse의 multipart parser 이전 request-body admission, parser 이후 form-field validation, pypdf security floor, test isolation을 한 canonical lineage에서 유지합니다. intervening descendants의 유효 test/security delta는 채택하되 generated repository doctrine과 과장된 security claim은 normal descendant로 수리합니다.

• protected base: develop@e06b1f3fb10903569124af011da213951e6e2473
• exact head: ebd6c71ba17151228c23d32705687097290c0c89
• lifecycle: Draft / mechanically mergeable / exact-head hosted evidence pending
• effective files: CHANGELOG.md, dependency doctoring, pyproject.toml, /parse source, focused parse/request-body/test-isolation/security tests, uv.lock
• .jules/sentinel.md는 protected-base blob과 일치하므로 effective diff에서 제거된 상태를 유지합니다.

RED → GREEN → repair lineage

• 선언된 oversized Content-Length는 body read 0회로 413, 길이가 없거나 신뢰할 수 없는 stream은 실제 누적 receive bytes로 제한하는 pre-parser RED를 /parse POST 전용 ASGI admission으로 GREEN 처리했습니다. PDF payload 20 MiB와 multipart/form framing budget 1 MiB를 분리해 총 21 MiB admission을 유지합니다.
• language/mode의 max_length=50은 parser 이후 FastAPI form-value contract입니다. 이것을 multipart parser 이전 memory budget이라고 주장하지 않습니다.
• 51-character regression은 tests/test_parse_endpoint_max_length.py에서 두 필드를 parameterize하고 HTTP 422와 FastAPI/Pydantic의 string_too_long location을 직접 고정합니다. 이 공개 validation shape를 존재하지 않는 sanitized response라고 표현하지 않습니다.
• focused fixture는 자신이 설치한 _runtime_settings override만 복원하며 다른 fixture의 app.dependency_overrides를 지우지 않습니다. 기존 destructive-clear 회귀도 별도 test-isolation contract로 유지합니다.
• pypdf>=6.16.2,<7.0와 lock 6.16.2를 유지합니다. 2026-09-05 재검증한 upstream advisory 기준으로 CVE-2026-84309는 6.16.0, CVE-2026-84310/CVE-2026-84311은 6.16.1에서 각각 patched이며, PyPI의 현재 latest 6.16.2는 이 floor보다 최신입니다. docs/doctoring/dependency-security-baseline.md에 CVE↔GHSA↔patched-version↔PyPI provenance를 APA-style traceability로 갱신했고, regression은 기존 CVE-2026-71852/71870과 신규 3건 모두 repository-wide suppression 대상이 아님을 고정합니다. 현재 strict PdfReader path에서 각 advisory가 반드시 reachable하다고 과장하지 않습니다.

sibling consolidation

• #786@842e12485827c6f27a52eef997fc4e18f8865741의 유효 pypdf declaration/lock/security intent는 이 lineage에 승계했습니다. 근거 없는 upload-read chunk 성능 실험과 no-op retrigger doctrine은 승계하지 않았습니다.
• #803@7d688fbf659a65faab8c1eb7c233243f920e29d7의 유효 delta인 language/mode max_length=50, 두 51-character 422 regressions, CHANGELOG 의미는 포함합니다. max_length 자체가 pre-parser memory exhaustion을 막는다는 global Sentinel doctrine은 결함이므로 승계하지 않습니다.
• #774@26f99339076c3d43913f62739fe4482a6fe19224의 유효 delta도 이 exact head가 완전히 승계합니다: 동일 form bounds, 동일 focused 422 regression contract, protected-base Sentinel 복원, 더 강한 bounded pypdf>=6.16.2,<7.0 declaration/lock/doctoring, 그리고 실제 pre-parser request-body control까지 포함합니다. #774의 pypdf>=6.16.0 무상한 declaration과 stale/과장 설명은 승계 대상이 아닙니다.

Promotion boundary

모든 source/doc/test 변경은 predecessor CI evidence를 무효화합니다. 새 exact head의 required tests/security/code-scanning/review evidence가 terminal GREEN이고 unresolved thread가 없으며 independent current-head review가 성립하기 전에는 Ready/merge-ready로 올리지 않습니다. Self-approval, administrator bypass, gate weakening, no-op retrigger, force push, destructive rebase는 사용하지 않습니다.

@claude Fresh test-isolation RED is now on exact head cbfd7b87515ac828b40515c552a3454abc5f673e: tests/test_test_isolation_contract.py rejects app.dependency_overrides.clear() in tests/test_parse_endpoint.py because that test does not own overrides installed by other fixtures.

Minimal GREEN on a normal descendant:

• in test_parse_form_field_max_length_exceeded, replace the direct app.dependency_overrides[_runtime_settings] = ... mutation with monkeypatch.setitem(app.dependency_overrides, _runtime_settings, ...), so pytest restores either the prior _runtime_settings override or absence automatically;
• remove the broad finally: app.dependency_overrides.clear() cleanup;
• retain the existing _parse_access_failure monkeypatch and both language/mode 51-character assertions;
• run the new isolation contract plus tests/test_parse_endpoint.py and request-body limiter regressions.

Do not clear or replace the whole override mapping, and do not create a source-neutral retrigger. If the branch advances, read/adopt the intervening delta and continue non-force.

Acknowledged. test_parse_form_field_max_length_exceeded 테스트 함수에서 직접 app.dependency_overrides를 덮어쓰지 않고 monkeypatch.setitem()을 사용하여 격리를 보장하도록 수정했습니다. 또한 요청 본문 길이를 제한하는 RequestBodyLimitMiddleware가 누락된 coverage(100% 달성)를 해결할 수 있도록 test_request_body_limit.py에 추가 테스트(test_request_body_limit_allows_short_body, test_request_body_limit_allows_short_body_other_event, test_request_body_limit_invalid_content_length)를 작성했습니다. 최종 100% 커버리지 GREEN 확인 후 제출합니다.
