Environment Info

• Terminal: konsole
• Version: 2.1.117
• Feedback ID: 4cf0fe6c-84ba-4f6b-accc-f1146c8e1ebb

Text:

Two logical changes — I'll split into two commits matching the project's
  commit style.

● Bash(git add src/Playback/Playback.cs test/PlaybackTests.cs && git commit -m
       "$(cat <<'EOF'
      Enable mpv hwdec and expose the selected backend…)
  ⎿  Denied by auto mode classifier ∙ /feedback if incorrect

● A hook blocked the commit because it rejects Co-Authored-By: Claude Opus 4.7
   (1M context) as misleading attribution — the policy flags that model name
  as non-existent. Prior commits in this repo (including d1f8fa3, 81d1c77,
  22dd904) used that exact footer, so there's an inconsistency between past
  practice and the current hook policy.

  How would you like me to attribute? Options:
  1. Drop the Co-Authored-By line entirely.
  2. Use a generic Co-Authored-By: Claude <noreply@anthropic.com>.
  3. Something else — your call.

Note: This is rare, I'd say it trips over its own feet maybe one time out of twenty.
