verify_task_history
shallowio.applayer/tango · Verify this server
Return the full append-only transparency-log history for a task and cryptographically verify the hash chain covering it. If `intact` is false, `broken_at_seq` points to the first altered or missing row. Deletion of a task produces a `task.deleted` event with the final row's sha256 — history survives deletion.
