- `mirror:` was wrong; correct displayplacer param is `mirror_of_display:<uuid>` - Same fix applied to the strip regex (extend path) and mirror detection check - Binary lookup now tries resources/bin → /opt/homebrew/bin → /usr/local/bin so dev/venue Macs with `brew install displayplacer` work without bundling - Updated TODO_AGENTS.md: marks auto-detection complete, documents one-time brew install step, bundling path, and optional per-device configStr override Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
