Outcome

This Draft preserves the bounded parser-admission and buyer-facing documentation delta while stacking it on the canonical dependency-security owner, #822.

Product boundary

  • NEWSDOM_MAX_CONCURRENT_PARSES is immutable per process, defaults to 1, and accepts 1..128.
  • Authentication precedes parser admission.
  • Saturation fails without waiting, before multipart-body handling, with 429, Retry-After: 1, and Cache-Control: no-store.
  • Leases are released across success, validation, backend failure, unexpected error, and cancellation.
  • /health remains liveness; /ready remains the fail-closed traffic-readiness boundary.
  • MinerU remains outside the approved commercial inbound baseline; [Commercial Compliance] Replace restricted MinerU runtime with commercial-policy-compatible parser boundary #671 owns replacement.

Owner stack and RCA

Exact predecessor head 042b5062166dc6392434ced7106eb52a7b66c52b failed for three independent causes:

  1. tests/test_docker_delivery.py required an obsolete bundled-MinerU sentence that contradicted the current fail-closed commercial boundary.
  2. tests/test_security_policy.py required the former personal repository and maintainer links after SECURITY.md correctly moved reporting to ContextualWisdomLab.
  3. Trivy found pypdf CVE-2026-84309/84310/84311 in the inherited 6.15.0 lock.

Ordinary two-parent commit d29ab194e72685369b8b7dc441377935461b21ad adopts #822 at ce66ad092c14f6002e67c7b30ea5742a4968b5c1, keeps its pypdf/HTTPX2 lock and regression contracts, and updates only the two stale documentation assertions. Commit 4824d880101c53cdc11e8104181ece60a71c6438 preserves protected develop's deletion of obsolete one-shot fix_pr.sh.

The PR base remains #822's branch. GitHub currently reports mergeable=false / mergeable_state=dirty; the former mergeable claim is stale. Keep the stack alive while its base/conflict is repaired; dependency files remain owned by the base PR.

Verification

Current exact head: dd5ebcfac3f0163fb083741ae834d4f304cb4797.

Commit dd5ebcfac3f0163fb083741ae834d4f304cb4797 repairs the three terminal pytest failures from run 35450770240: CHANGELOG tests now require the organization-owned URLs already present in CHANGELOG.md, and the installation test now requires the documented loopback bind instead of 0.0.0.0. The implementation and public docs remain unchanged by this repair.

At the first current-head readback, no exact-head workflow run had materialized. Predecessor results are evidence only: container-image 35450770208, scorecards 35450770202, CodeQL 35450770286, and clusterfuzzlite 35450770211 succeeded; tests 35450770240 failed on the three stale assertions repaired above.

Public-surface evidence

  • GitHub reports has_pages=true.
  • The repository homepage currently points to https://contextwisdomlab.github.io/newsdom-api/, which returns 404 because the organization name is misspelled.
  • https://contextualwisdomlab.github.io/newsdom-api/ returns 200, but its HTTP Last-Modified is 2026-08-11 and is not evidence that this PR deployed.
  • This head owns .github/workflows/gh-pages.yml, mkdocs.yml, and manual/index.md; central .github#2110 owns the corrected desired homepage and settings reconciliation.

Do not transfer predecessor evidence. Keep Draft until #822 and this head have terminal required Checks and current independent review. No self-approval, gate weakening, force push, destructive rebase, or unchanged rerun is requested.

🚨 Severity: HIGH
💡 Vulnerability: `hmac.compare_digest` throws an unhandled `TypeError` when it receives non-ASCII strings. By sending an `Authorization` header with non-ASCII characters, an unauthenticated user could trigger an unhandled 500 Internal Server Error, leading to a potential Denial of Service (DoS).
🎯 Impact: Attackers could cause application crashes by passing Unicode characters in the Authorization header.
🔧 Fix: Encoded the inputs to bytes via `.encode("utf-8")` before comparing, which `hmac.compare_digest` processes safely. Added test for non-ASCII input handling.
✅ Verification: Ran `uv run pytest` successfully.

Merge Risk: 🟡 Moderate · up to 042b5

The PR adds bounded parser admission and refreshes installation and public documentation, but it is not merge-ready while readiness can accept an unapproved parser, benchmark reports omit required reproducibility data, and the documented all-interface listener can expose unauthenticated operational endpoints on reachable hosts.

README/public-surface follow-up on exact head 042b5062166dc6392434ced7106eb52a7b66c52b: SECURITY.md still pointed private vulnerability reporters to the pre-organization Seongho-Bae/newsdom-api advisory route and a personal maintainer profile. The canonical public-surface branch now uses the exact ContextualWisdomLab/newsdom-api Security Advisory path, removes the personal-profile dependency, and keeps a fail-safe instruction to use an established private maintainer channel if the repository feature is unavailable. No security control, parser behavior, dependency, or license exception changed. All predecessor-head checks/reviews are historical after this documentation commit; reacquire exact-head evidence before integration.

Exact-head admission correction for 042b5062166dc6392434ced7106eb52a7b66c52b (2026-09-19 UTC).

This PR is not merge-ready:

I am returning #548 to Draft. Repair the two stale assertions against the exact current documentation contract, then ordinary-restack/adopt the verified #822 dependency owner without discarding #548's capacity/public-surface delta. Require fresh exact-head pytest, Trivy/Security, CodeQL/SAST, and independent review before Ready.

seonghobae marked this pull request as draft September 19, 2026 12:11
Preserve the bounded parser/public-surface delta while adopting the canonical pypdf and HTTPX2 security floor from #822. Update the two stale documentation assertions demonstrated RED by exact-head CI; no product gate or coverage threshold is weakened.

Exact-head review repair for 70d02297679f364acda47e895d9dbcd72e1a55b5.

Verified findings were repaired without weakening admission or security gates:

  • RED tests bb7474c5, a370d2e6, and f8efe441 cover the exact 20 MiB fixture boundary, complete reproducibility evidence, schema 1.2.0, and a valid-auth legacy MinerU executable that must remain unready.
  • ed4d9341 rejects oversized fixtures and requires a strict execution-image/CPU/memory/storage/filesystem/lock/SHA/worker/cache manifest; 24b47f7c binds the same fields into the closed JSON Schema.
  • f2443569 makes default readiness fail closed until an approved parser backend exists. An injected probe remains available for isolated tests; the legacy executable alone cannot make production ready.
  • 87bdd143, 9ab513aa, 96fb2d8b, and ae27e4c3 repair dotenv ordering, RuntimeSettings/readiness documentation, Markdown heading spacing, and the local loopback bind.
  • 210b7a7e documents the required environment-manifest input and schema revision.

Exact changed Python files parse successfully. Focused in-memory contracts verified manifest unknown-field rejection and the strict schema field set. Fresh hosted tests/security/CodeQL are queued, so this is not a GREEN or merge claim; the PR remains Draft and no manual rerun was requested.

Exact-head repair evidence (2026-09-26 UTC)

  • predecessor head: 70d02297679f364acda47e895d9dbcd72e1a55b5
  • failing tests run: 35450770240 — 3 failures / 526 passed / 100% source coverage
  • RCA: two tests required obsolete Seongho-Bae/newsdom-api links although CHANGELOG.md already uses ContextualWisdomLab/newsdom-api; one test required --host 0.0.0.0 although the reviewed installation guide intentionally binds 127.0.0.1
  • non-force current head: dd5ebcfac3f0163fb083741ae834d4f304cb4797
  • changed by repair: tests/test_changelog.py, tests/test_manual_docs.py only
  • public-surface readback: has_pages=true; configured homepage https://contextwisdomlab.github.io/newsdom-api/ returns 404; canonical https://contextualwisdomlab.github.io/newsdom-api/ returns 200 with an older 2026-08-11 artifact
  • publication owner preserved: .github/workflows/gh-pages.yml + mkdocs.yml + manual/index.md
  • conflicting type: feature alias removed; canonical enhancement / priority: medium / status: needs-review retained

The PR remains Draft and dirty against its stacked base. No predecessor Check is transferred and no fresh Pages deployment is claimed.
