git_worktree_provider_ref_mismatch

Error message

Issue ${issue.identifier ?? issue.id} expected git worktree "${input.persistedExecutionWorkspace.providerRef}" but adapter cwd resolved to "${effectiveCwd}".

What it means

A git-worktree-based execution workspace was expected (providerRef names the registered worktree), but the adapter's resolved cwd points somewhere else. This mismatch guard fires during heartbeat pre-flight to prevent runs that would execute outside the persisted worktree.

Solutions

1. Restore or recreate the git worktree so the adapter cwd matches the persisted provider ref.
