# Guru Reactivate Task

Reactivate is the normal archived-task continuation owner. It is distinct from
`guru-restore-archived-task`: it preserves the original task identity, moves a
single archive copy back to active, and routes either requirements, planning,
implementation or evidence refresh. It never reopens an Issue implicitly.

Before mutation, the AI reviews one exact target baseline and either an exact
reusable clean branch/worktree or a new branch/worktree plan. The deterministic
executor prepares that workspace, moves the original archive to the single
active locator, refreshes task metadata and ignored runtime mappings, and
invalidates prior Finish and Cleanup receipts while incrementing the task
lifecycle generation. It never creates a replacement task.

If stdout is lost after that transaction, retry the exact same public and
semantic input. The executor rematerializes the same typed result only when the
active task, reviewed workspace/branch/base, both mappings, and invalidated
Finish and Cleanup receipt state still form the complete transaction post-state. It creates
no recovery artifact; partial or mismatched state fails closed.
