Root Cause

● 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.

Code Example

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

  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.

extent analysis

TL;DR

The issue can be resolved by updating the Co-Authored-By line to a format that the auto mode classifier recognizes as valid.

Guidance

  • The classifier is flagging "Co-Authored-By: Claude Opus 4.7" as misleading attribution, suggesting that "Opus 4.7" is not recognized as a valid model name.
  • To resolve the issue, consider using a generic Co-Authored-By line, such as "Co-Authored-By: Claude [email protected]", as suggested in the issue.
  • Review past commits in the repository to ensure consistency in attribution formatting.
  • If the issue persists, consider dropping the Co-Authored-By line entirely or exploring alternative attribution formats.

Notes

The issue seems to be related to the specific formatting of the Co-Authored-By line, and updating it to a recognized format should resolve the issue. However, it's unclear why the classifier is flagging "Opus 4.7" as non-existent, despite its use in prior commits.

Recommendation

Apply workaround: Use a generic Co-Authored-By line, such as "Co-Authored-By: Claude [email protected]", to avoid the classifier flagging the attribution as misleading.
