Apply fixes from a full-repo review (code, tests, docs). Security / correctness: - Clamp attacker-controlled PNG/caBX chunk lengths to the remaining file size in metadata.py and noai/c2pa.py (a malformed length no longer drives a multi-GB read); skipped chunks seek instead of read. - noai/isobmff.strip_c2pa_boxes is now fail-safe on a malformed box: return the original bytes with a warning instead of silently truncating the tail, so metadata --remove can no longer emit a corrupt file. - doubao_engine._fixed_alpha_map clamps the glyph box to the image (no crash on degenerate width-vs-height). - watermark_remover._run_region_hires gates the phaseCorrelate offset on response and magnitude (a spurious shift no longer garbles text) and drops the generator after a CPU fallback (no MPS/CPU device mismatch). Robustness: - gemini_engine, doubao_engine, region_eraser normalize grayscale and RGBA inputs to BGR at the engine entry points. - image_io.imwrite returns False on an unwritable path (matches cv2). - invisible_engine guards a None imread result before use. - trustmark_detector._decoder uses a double-checked threading lock. - ctrlregen.tiling.tile_positions raises on overlap >= tile. - humanizer chromatic shift no longer wraps opposite-edge pixels. - identify OpenAI caveat keyed on the normalized vendor, not a substring. - Remove the dead "visible --detect-threshold" CLI option. - publish.yml verifies the release tag matches the package version. Docs: - README strength 0.05 to 0.10; .env.example HF_TOKEN marked optional; doubao_capture README updated to reverse-alpha-only; CLAUDE.md synced with the new behaviors and the batch command. Tests: new test_security_clamp.py for the read clamp and isobmff fail-safe; erase CLI coverage; integrity-clash rule 2 end-to-end; multi-tag EXIF survival and cross-format strip guards; channel/size, tiling, humanizer, and imwrite regressions. Full suite 493 passed, 2 skipped; ruff and pyright src/ clean. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
