ci(noema): review binary-only document PRs via a base/head object diff - #2330
seonghobae wants to merge 5 commits into
Conversation
A binary DOCX/HWPX/PDF/image change arrives as 'Binary files ... differ' with no hunk, so Noema had no changed line to cite and every formal verdict failed; PDF/image bytes were also decoded into the prompt. Materialize base/head blobs, extract hashed document objects under fail-closed safety checks, emit document_diff_review.v1, and render the changes as synthetic hunks whose line numbers are object ordinals.

Align the envelope with contextual-orchestrator#1220: cut object text on UTF-8 byte boundaries (8 KiB) and count the 256 KiB total in bytes, keeping changed objects before unchanged context. Scan every extracted base/head object for participant or secret patterns, and apply the same gate to the full extracted document body in the changed-file context.

budget is non-positive, or UTF-8 truncation produces an empty string; preserve
the existing control sanitization and boundary-safe truncation otherwise. This
keeps the surrounding change object and ordinal while allowing _line to use the
existing hash-only marker path.
- Around line 406-421: Update the package-object fallback in the changed-object
extraction flow so it runs whenever changed is empty, including when only
base_raw or only head_raw exists. Set the package change to modified, added, or
removed based on blob presence; compute each hash only for an existing blob, use
None for the missing side, and record ordinals with None for the missing side.

Exact-head finding (e6f0671f6158b48d853b483b00c198051f3ee821): DOCX/HWPX object extraction은 substantive evidence를 만들지만, PDF/image는 현재 DocumentObject("page", "blob", sha256, None) 한 개뿐입니다. 그런데 이 hash-only object를 synthetic changed hunk로 만들어 기존 changed-line validator가 formal verdict evidence로 인정하게 됩니다. 즉 “변경이 있었다”는 것은 증명하지만 “무엇이 바뀌었는지”는 전혀 관찰하지 못한 상태에서 Noema가 APPROVE까지 낼 수 있는 evidence gap이 생깁니다. 본문도 PDF page text/render/OCR을 아직 추출하지 않는다고 명시하고 있으므로, 이는 단순 품질 한계가 아니라 formal-review admission 문제입니다.
현실적인 RED를 추가해 주세요. PDF-only 또는 image-only PR에서 base/head bytes가 의미적으로 반대되는 내용을 담되 현재 extractor가 hash만 제공하도록 하고, mocked provider가 finding 0건/승인 응답을 내면 현 gate가 formal APPROVE까지 진행하는지를 end-to-end로 확인해야 합니다. 이 경로가 GREEN이면 안 됩니다. opaque-only changed object에는 manual_or_visual_review_required처럼 formal approve를 fail closed시키거나, released local renderer/text extraction/OCR 또는 명시적으로 허용된 multimodal route가 citable page content를 만들어 준 경우에만 substantive verdict를 허용해야 합니다. Figure의 ‘image hash changed + unchanged caption’ 같은 deterministic rule은 별도 finding으로 유지할 수 있지만, hash delta 자체는 semantic approval evidence가 아닙니다.
Acceptance는 최소 (1) DOCX/HWPX extracted-text 변경은 현 object-level path로 formal verdict 가능, (2) textless PDF/image-only semantic change는 content evidence 없이는 formal APPROVE 불가, (3) visual/text extraction이 생기면 page/region provenance와 hash를 결합해 exact object citation 가능, (4) raw bytes/media는 계속 runner 밖으로 나가지 않음입니다. 현재 상태는 binary false-negative를 줄였지만 opaque binary에 대해 false-GREEN approval을 만들 수 있어 Release/Scientific Evidence Gate는 아직 FAIL로 봅니다.
A PDF/image or uncaptioned figure object only proves bytes changed, so an approve citing it is rejected and the prompt asks for comment or request_changes. Also give added/removed packages without extractable objects a citable package object, and re-read a truncated diff before searching for binary stanzas.

The approve guard scanned rendered diff text, so a captioned image swap (not rendered as hash-only) and a hash-only line past MAX_DIFF_CHARS both slipped through. Compute path#locator ids of changed figure, page and textless package objects from the envelopes, return them from augment as review metadata, list them in the prompt and refuse any approve while one is present.

Root cause
Binary files a/x.docx and b/x.docx differwith no hunk.changed_diff_locations()then returns an empty set, andvalidate_substantive_verdict()raises "requires parseable changed-line evidence" on every approve or request_changes. Noema can never give such a PR a formal verdict. An empty textual patch means GitHub cannot render a textual diff; it does not mean nothing changed.fetch_file_content_at_ref()decoded PDF and image bytes witherrors="replace"straight into the prompt.Change
scripts/ci/document_blob_diff.py(stdlib only) extracts DOCX, HWPX and PDF/image content into ordered, sha256-hashed objects:binaryItemIDReffigures.pageobject.styleobject, so it never reads as "no change".document_diff_review.v1envelope. It matches contextual-orchestrator#1220 (head 6e2269a1); all five fixture envelopes (DOCX modified+figure, PDF added, PDF removed, DOCX style-only, HWPX) pass that PR'svalidate_document_diff_envelope.noema_review_gate.augment_binary_document_diff()runs on both the direct path and the two-phase path. It fetches the base blob at the merge base and the head blob, using contents for the SHA and Git blobs for the bytes, and replaces each binary document stanza with synthetic hunks whose line numbers are object ordinals. The existing citation validator accepts findings on document objects without changes. Opaque binaries are no longer decoded into context.Tests
tests/test_document_blob_diff.py: 37 passed. RED→GREEN: the binary-only request_changes integration test, the fail-closed augmentation test, and the no-raw-decode test fail on the previous gate (3 failed) and pass now. The raw binary-only diff still cannot carry a formal verdict; a characterization test pins that.noema_review_gate.pylines 868-869, the contents-API malformed-base64 branch, were already uncovered on main at lines 862-863.
