Previous sample `TomorrowNeverDies-...ac3` was malformed (started with bytes 0x84 4F 59 11, not AC3 sync 0B 77) — validator correctly rejected it, so the old 100%/100% number was a false positive from trial inheritance.

| Monkey's AudioAPE (Monkey's Audio) | 99% | 100% | Linux · macOS · Windows | MAC header + descriptor + per-frame CRC32. Full deep-decode validation now wired via vendored upstream Monkey's Audio SDK 12.73 (`deps/libape/`, BSD-3 since 2023). The validator runs structural rigor first (descriptor, header, seek-table monotonicity, audio-region bounds, field sanity, version range) then decodes every frame and surfaces per-frame CRC32-over-decoded-PCM mismatches via the C-shim `validate_ape_decode_check`. Truncation is caught either by the structural seek-table walk (modern v3980+ has audio_data_length) or by the decoder's sample-count-mismatch path. Synthetic 16 KB corpus is now a real APE encoded by the SDK from white-noise WAV (\`mac -c2000\`), so it actually decodes; sniper hits 99% (only the descriptor MD5 bytes — which are byte-level metadata not bitstream — escape detection in some random flips), shotgun hits 100%. Tested with the in-tree Zig tests + tests/cli/ape_validation (11 PASS). |

Block-checksum sub-block (`ID_BLOCK_CHECKSUM`) catches header/bitstream tampering at open-time; post-decode CRC catches arithmetic drift; truncation surfaces as decoded < expected sample count. |
