A live smoke test of buildArgs' argv against the bundled yt-dlp + ffmpeg found
that ffprobe.exe was never bundled (resources/bin/ shipped only ffmpeg.exe).
yt-dlp resolves both from --ffmpeg-location, so duration-aware post-processing
failed at runtime for every user with "ffprobe not found": --sponsorblock-remove,
--force-keyframes-at-cuts, and --split-chapters (CODE-AUDIT C1).
- Bundle ffprobe.exe (matching n8.1.2 LGPL build, sha256-verified against the
already-bundled ffmpeg.exe) and document it in resources/bin/README.md as a
required binary; correct the stale "not committed to git" note.
- Guard startDownload against a missing ffmpeg.exe/ffprobe.exe up front so the
failure is a clear AeroFetch error, not a cryptic yt-dlp postprocessing one
(new getFfprobePath() in binaries.ts).
- Expand test/real-download.integration.test.ts from 2 to 8 live cases: crop,
sponsorblock-remove, audio opus re-encode, mkv+vp9 merge, subtitle+chapter
embed, restrict-filenames, download-archive skip, and Phase C extra-args.
All 8 pass against live yt-dlp + ffmpeg.
- ROADMAP: mark the Phase A/B/C smoke-test caveats done. CODE-AUDIT: add C1.
