feat(review): fail-closed binary document diff review envelope - #1220
Merged
Merged
Conversation
GitHub has no patch for DOCX/HWPX/PDF/image changes, so a binary-only research-document PR cannot get a substantive Noema review, and sending the binaries to a remote model would leak originals. Add POST /v1/document_diff_reviews and document_diff_review.v1: the review leaf sends locally extracted base/head page/object records (hashes plus bounded text, no pixels). The gateway rejects unknown fields, inline binary/media, credential shapes, resident registration numbers, participant-data paths or a missing attestation, and hash/change inconsistencies before any provider call. Model findings must name an envelope object and quote only envelope text; a deterministic rule flags a changed figure whose caption did not change. ADR 0136 and a doctoring runbook record the owner split with the .github lead (extractor/differ on the runner) and the evidence boundaries.

- Around line 358-416: Update validate_document_diff_findings so every model
finding must quote at least one envelope text source: evidence_base,
evidence_head, or related_evidence. Remove the _TEXTLESS_KINDS exception from
the no-evidence check while preserving acceptance of textless objects when their
own or related object text is quoted.
In `@contextual_orchestrator/server.py`:
- Around line 6677-6689: Update the document diff review flow around
coordinator.complete to enforce the private-review ZDR policy: determine whether
the request is private, validate the result with _validate_zdr_only, and pass it
explicitly as zdr_only=zdr_only; if this endpoint handles only private
documents, pass True directly. Preserve the existing routing and attribution
behavior.

Address review on #1220: - Pass zdr_only to the coordinator. Documents default to zero-data- retention routes; a caller may send zdr_only=false explicitly (public repository). Without an eligible route the request fails closed with no provider call. - Every model finding must quote at least one envelope span; hash-only figure/page findings without a quote are rejected.

The planning ADR identifier test globs NNNN-*.md, so the date-prefixed 2026-09-10-request-partitioning.md was read as ADR "2026" with no id. Rename it to 0135-whole-request-partitioning.md with front matter id "0135", byte-identical to the blob open PR #1088 already assigns (f85f8bf), so the two branches converge. 0134 is the highest number on origin/main; 0135 is used only by #1088 for this same document and 0136 only by #1220. No tracked file referenced the old filename. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01LeLbwEgYXzCzpaFMTHDcBS

…#1083 step 1) Review changes for draft PR #1257 (3/3: docs): - the receipt document is the only decision authority; the client never produces or interprets a version or decision (replaces "no schema can represent" wording); - evidence pack = the #2260 pack, with the stricter-than-workflow differences listed as owner decisions; - reason-code enum and class mapping, served_route const, local-registry-only $ref resolution, .gitattributes byte stability; - explain the 0137 number (0135 on several open branches, 0136 on open PR #1220).

GitHub shows no patch for DOCX/HWPX/PDF/image changes. Noema's verdict gate needs changed-line evidence, so a binary-only research-document PR cannot get a substantive review. The
