📝 WalkthroughWalkthrough읽기 전용 PNG 중복 감사 기능을 추가했습니다. BLAKE3 바이트 해시와 정규화된 RGBA16 픽셀 다이제스트로 그룹을 만듭니다. 파일 객체 정체성과 입력 크기를 검증합니다. 고유한 Pareto keeper만 표시하며 파일 정리 실행은 비활성화했습니다. Changes사진 중복 감사
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🔴 Critical · up to The read-only audit can currently fail validation entirely, consume excessive memory on large inputs, and publish evidence for active files contrary to the product contract; concurrent filesystem changes and wire-format drift can also reduce evidence integrity or compatibility. Merge should be blocked until the workflow, input safeguards, and admission contract are corrected. Sequence Diagram(s)sequenceDiagram

In @.github/workflows/test.yml:
- Line 63: Update the workflow step containing the cargo test command to use a
YAML block scalar with run: |, placing the command on the following indented
line so the photo_duplicate::tests:: filter is parsed safely.
In
`@docs/architecture/adr/0012-photo-duplicate-evidence-without-composite-scoring.md`:
- Around line 27-28: PR objectives의 active-use 처리 설명을 현재 계약에 맞게 수정하세요.
audit_photos는 입력 거부만 집계하고 active-use evidence를 검사하거나 active files를 reject하지 않으며,
execute_photo_duplicate_cleanup은 현재 unavailable을 반환합니다. active-use evidence 수집은
향후 fresh execution preflight에서만 수행된다고 ADR과 CHANGELOG의 정의와 일치시키세요.
In `@src-tauri/src/photo_duplicate.rs`:
- Line 71: Update the path validation in audit_photos to reject provider-managed
locations for both absolute and relative PathBuf inputs; use absolute-path
normalization or component-based matching so paths such as
Library/CloudStorage/OneDrive-Personal/image.png cannot bypass the existing
check.
- Line 138: Update the decoded pixel digest calculation around blake3::hash so
it hashes the raster width and height together with the normalized sample bytes,
ensuring dimensions distinguish otherwise identical 1×N and N×1 images while
preserving the existing digest output flow.
- Line 82: hash_current_file에서 admission_blocker로 진행하기 전에 인코딩된 입력 바이트 상한을 검사하도록
수정하십시오. 제한을 초과하면 read_to_end나 전체 길이 예약을 수행하지 말고 기존 호출자가 안정적으로 처리할 수 있는 일관된 거부
오류를 반환하십시오.
- Around line 282-283: Restore active-file rejection in the audit path around
audit_photos so files currently in use, including PNGs, are not returned as
valid evidence. Preserve the read-only audit boundary while reusing the existing
platform-appropriate active-use check or equivalent preflight behavior.
- Line 86: Update the PNG decoder initialization in the normalization flow
around normalize_rgba16 to apply a transformation that expands grayscale/RGB
tRNS transparency into the decoded alpha channel, or otherwise incorporate tRNS
values before digesting. Preserve the existing indexed-color and unsupported
bit-depth rejection behavior.
In `@src-tauri/tests/photo_duplicate_decode_bound_contract.rs`:
- Line 51: write_declared_grayscale_png으로 생성하는 두 테스트 fixture의 크기를
MAX_NORMALIZED_IMAGE_BYTES를 초과하도록 변경하십시오. 각 테스트가 next_frame까지 진행되지 않고 크기 제한 초과
오류를 검증하도록 하며, 제한과 같거나 작은 20,000×1 및 8,192×8,192×8 설정은 사용하지 마십시오.
In `@src-tauri/tests/photo_duplicate_input_contract.rs`:
- Line 26: Update the expected photo error identifier in the test around the
animation PNG case to match the value returned by inspect_photo, using one
consistent public contract identifier across the implementation and test.

Purpose
Add a Rust-first, read-only exact-photo duplicate audit without granting deletion authority. The current boundary is bounded local PNG evidence only: exact grouping may be reported, while perceptual grouping and filesystem mutation remain unavailable until calibrated evidence, an unambiguous keeper decision, and a fresh execution preflight exist.
Current exact state — 2026-09-05 KST
main:0e90f9cebadbd7f59606baaec4ca1d2f178c899a;3e33229b4157a084a1985a1c7e952f98a64f25e3;94a07ca11815312e5fd44f7bc443cca6de09187e;Photo evidence boundary
Managed Photos/File Provider roots and dataless placeholders are rejected before content open through shared classifiers, without rejecting unrelated local names. Encoded input is capped at 64 MiB before allocation and again on the opened handle; decoded and normalized allocations retain separate 256 MiB and 512 MiB ceilings. One audit admits at most 4,096 inputs and 16 GiB of declared bytes before rejection evidence.
PNG decoding uses
Transformations::EXPANDso palette/low-depth samples andtRNStransparency participate in normalized RGBA16 evidence. Exact decoded identity is v2-domain-separated and binds raster width and height. png 0.18 metadata evidence uses actual raw observations (gama_chunk,chrm_chunk,srgb,icc_profile). Incomplete audits emit structured JSON but the shipped CLI exits 3 when evidence is incomplete or no supplied input was inspected. ADR 0012 remains Proposed until integration.docs/product-technical-gap-baseline.mdstays delegated to #315 and is not owned by this runtime lane.Safety boundary and buyer gap
This PR is audit-only. Active-use evidence belongs to a future fresh execution preflight; cleanup execution and permanent deletion remain unavailable. A displayed Pareto keeper is evidence, not deletion authority. Near-duplicate/perceptual cleanup still requires calibrated thresholds, provenance/quality/lineage evidence, customer resolution of ties, fresh identity/materialization/active-use preflight, reversible quarantine/Trash, durable receipt/journal, and tested undo.
Required before integration
Keep Draft until #264 is itself eligible to integrate and one unchanged #313 exact head has terminal-success applicable Test, Release, Security, SAST/CodeQL and central gates after fresh review. Queued, pending, stale, predecessor, cancelled, skipped-required, or synthetic-only evidence is non-passing. No force-push, destructive rebase, self-approval, gate weakening, or administrative bypass.
