3.9.3 (2026-10-11)

Cue WAVE tracks with an over-declared header now convert (#68232–#68237)

• A WAV whose header claims more audio than the file contains no longer fails the conversion. Both encoders trust the data chunk's size field, so a file that is short of its declared length — the widely distributed Policenauts Saturn English patch ships exactly this shape, one CD frame (2,352 bytes) over-declared on all three discs — made chdman abort with Error reading input file (...wav) and the built-in CHDSharp fallback report Unexpected end of file (...wav). The app now detects the over-declaration before encoding and clamps the data and RIFF sizes to the bytes actually present, so the conversion reads the audio that exists. The repair happens on a private copy; the user's files are never modified.
• Only the damaged WAV is copied. The repaired work set is staged on the cue's own volume and references every other file (including multi-hundred-MB disc images) in place by relative path. When a same-volume location is unavailable it falls back to the full copy-based work directory, which repairs the WAVs there.
• Both encoders produce the same result for a repaired set: a byte-identical CHD from chdman and the built-in CHDSharp encoder (verified against the real Policenauts disc 1 files).

Housekeeping

• PbpFileIntegrationTests now early-returns when its local samples are absent, matching every other integration group (§11.5); without samples the tests report as passed instead of failing on Assert.NotEmpty().
• MDSSharp published as 1.2.1 with repository metadata pointing at the renamed CHD Studio repository; no functional changes.
• Package updates: Avalonia 12.1.3 → 12.1.4, SharpCompress 0.50.4 → 0.50.5, Meziantou.Analyzer 3.0.294 → 3.0.299, xunit.runner.visualstudio 4.0.0 → 4.0.1.
• Test suite grew to 1133 tests (1104 unit + 29 integration) across 58 test classes, including WavHeaderSanitizer unit coverage, the CueWorkDirectory repair paths and a real-chdman end-to-end regression test for the repaired cue set.
