- [x] Verify the official libaom all-intra, CDF-update, and temporal motion-field sequences through exact native output, selected syntax coverage, normal/scalar dispatch, constrained tracked allocation, and the family-owned JPEG-style predictor operator architecture.
- [ ] **Current:** continue inventorying and removing every remaining valid AV1 still-image unsupported branch, adding exact independent compression-tool fixtures to the profile-matrix regression gate.
- [x] Add the missing official ten-bit sequence evidence from libaom's pinned test-data manifest. All ten active-film-grain YUV420 frames and all ten monochrome frames match the pinned generic libaom native Y4M samples exactly under normal and scalar `FeatureTestRunner` dispatch, and both complete sequences pass through a 2 KiB constrained tracked allocator with balanced exactly-once returns. The three new focused cases and all 20 official-sequence regression cases pass without failures or skips, the scoped Release test-project analyzer build completes with zero errors and 1,011 repository warnings, Roslynk reports zero compiler errors, and `git diff --check` is clean. The existing production decoder required no correction. Commit `deefeba2340932909aa3e27516d965a294cf6faa` records the checkpoint.
- [x] Add official minimum- and maximum-quantizer dependent-frame evidence for the eight- and ten-bit libaom matrices. The four retained streams and pinned generic-libaom Y4M references pass exact native comparison under normal and scalar `FeatureTestRunner` dispatch, and the combined sequences pass through a 2,560-byte row-aligned constrained tracked allocator with balanced exactly-once returns. All three new focused cases and all 23 official-sequence regression cases pass without failures or skips, the scoped Release test-project analyzer build completes with zero errors and 1,011 repository warnings, Roslynk reports zero compiler errors, and `git diff --check` is clean. The existing production decoder required no correction.

- [x] Add exact official frame-size evidence at all four corners of libaom's 196-to-226-pixel matrix. Both frames from each retained stream match the pinned generic-libaom native Y4M samples under normal and scalar `FeatureTestRunner` dispatch, and all four sequences pass through a 1 KiB constrained tracked allocator with balanced exactly-once returns. Both new focused cases and all 25 official-sequence regression cases pass without failures or skips, the scoped Release test-project analyzer build completes with zero errors and 1,011 repository warnings, Roslynk reports zero compiler errors, and `git diff --check` is clean. The existing production decoder required no correction.
- [ ] Complete the remaining HEVC still-image profile and Range Extensions matrix with exact independent native-plane and presentation evidence.
- [ ] Close shared decoded presentation, ICC, alpha, grid, transform, metadata, and animated AV1/HEVC decode gates.
- [ ] Implement and independently verify real AV1/AVIF still encoding.
