Continuing the same external audit report's architecture/data-integrity/reliability findings:

• _contract.py declared encoder:aac unconditionally required for audio.py,
  loudness.py and join.py, but all three pick their audio codec from the output
  extension via audio_codec_for() (falling back to AAC only when the extension
  isn't otherwise covered) -- so doctor reported these tools entirely unusable
  on an ffmpeg build without an AAC encoder, even though they can still produce
  e.g. a .flac output with no AAC involved at all. Moved to optional with a
  when, matching the pattern cut.py/silence.py already used; join.py's
  libx264 requirement was similarly conditioned on joining video inputs.
  export.py's AAC when also named "any preset except gif", though prores
  (pcm_s16le) and copy (stream copy) don't use AAC either -- corrected.
• batch.py's --recipe project mode ({"project": "p.json", "clip_key": N})
  computed its cache key by hashing only that small outer dict, never the
  referenced project file's own content -- so editing p.json (an export preset
  swapped from copy to a real re-encode, captions text, anything) without
  touching the recipe file itself left the cache key unchanged, and the stale
  cached output was silently served for the new settings. Fixed by folding the
  referenced file's content into the key.
• batch.py's cache file was written with a plain write_text(), not atomic --
  a process killed mid-write left a truncated file that the next run's
  json.loads() treats as corrupt and silently discards, losing every prior
  cache entry, not just the interrupted one. Fixed via a sibling temp file +
  os.replace().
• render.py's default work directory name came only from the output path (e.g.
  final_work), with no PID or timestamp -- two concurrent render.py runs
  targeting the same output (a batch.py "project" recipe processing several
  files in parallel, or simply two runs by mistake) shared the same work
  directory and clobbered each other's same-named intermediates mid-run. Fixed
  by suffixing the auto-derived default with this process's PID (an explicit
  --work is left as given, since the caller asked for that exact path).
• bin/install.js deleted an existing install (rmSync) before copying the new
  one in -- normal install, not just --uninstall. A process killed partway
  through the copy (Ctrl-C, disk full, a permission error) left the target
  either empty or half-populated, destroying a working previous install for
  nothing worse than an interrupted upgrade. Confirmed live: a simulated crash
  mid-copy left the target directory completely empty, an existing marker file
  gone. Fixed by copying into a scratch directory next to the real target first,
  then swapping it into place with a single rename.
