debpalashandClaude Opus 4.8 63d40c33ce fix(synth): #1227/#1221 review — classify on a marker, not on shared wording
Two P1s, both correct:

- The enriched write failure lost its class. _describe_write_failure rewrites
  the message, so the word "libsndfile" no longer appears — classify()
  returned "" and the auto bug report and docs deeplink had nothing to name.
  Worse, my own end-to-end test allowed "" as a pass, which is exactly why it
  went unnoticed. audio_io now emits a stable AUDIO_WRITE_FAILED_MARKER,
  failure.py matches that, and the assertion is exact.

- "error opening" was far too broad. It appears whenever a model, archive or
  config file fails to open, so any such failure was handed the audio-file
  remedy (check your disk, add an antivirus exclusion). Dropped in favour of
  the marker; a regression test pins that a corrupt-model-archive error keeps
  its own guidance.

A third test pins the marker across the two modules — core/ cannot import
services/, so the string is duplicated by necessity, and a reword on either
side would silently un-classify every enriched write failure.

CHANGELOG entries shortened with refs last (CodeRabbit).
