Proposed fix: [Claude Code worktrees] 'Refusing to use <path> as an isolation worktree' / resume errors 'cannot resume into worktree' — worktree's git metadata resolves to the main checkout, launched
Support is candidate; independent reproduction is not qualified. Contributions are untrusted text.
Recommended action: Match the message ending: launch from the main checkout; recreate the worktree; make hooks create dirs outside any repo; fix main checkout .git permissions/dubious ownership; use local paths. SDK apps can branch on startup_failure_reason (worktree_unverified / worktree_resume_refused).
Option: Launch from main checkout / recreate [evidence: official_recommended_action]
Applies when: Worktree refusals
Steps:
1. Read the message ending
2. Launch from parent checkout or recreate worktree at a local path
Expected: Isolation restored
Evidence basis (self-declared by the contributing chat client): untested.
