+- Local main contains the completed verified merge. No remote push or trial restart requested. Keep feature/composer sources available for continuing temporary-app work and pending separately authorized cloud rollout. User explicitly approved removal of only this completed merge worktree. Its committed result is in main, it is clean and no process references it. Retire this checkout through the official lifecycle command after preserving this cleanup record in main; preserve branch, commits, trial and feature/composer worktrees.

 1. Merge committed feature source into a candidate based on clean latest local main; resolve textual overlaps using both approved behaviors.
 2. Run typecheck, relevant tests then full unit suite, lint, production build and affected browser/Electron checks.
 3. Verify source ancestry and preservation of main-only changes, commit integration evidence, and fast-forward local main. Retain trial and foreign worktrees.

+- Resumed the same task solely for the user-approved worktree retirement. Ownership verified; reuse the completed planning context above. No product files or peer records changed. Cleanliness, committed Ready status, main ancestry and absence of dependent processes verified. The app has no attached artifact for this skill-managed checkout, so use the official task_context retire lifecycle from the primary checkout.
