AccessDenied

Error message

AccessDenied

What it means

Sentinel variant of the bun_core Error enum mirroring errno EACCES/EPERM: the operation was denied by file permissions or privilege level. One of the errno-category variants kept local because bun_core cannot depend on bun_errno; callers switch on the enum variant.

Solutions

1. Fix ownership/permissions on the target
2. Re-run with appropriate privileges
