-"""Fail-closed bootstrap for narrow Owner-delegated Agent Task admission.
-
-This module solves the authorization bootstrap problem without turning the
-runtime anchor into a writer and without weakening TaskPrincipal semantics.
-
-Security model:
-
-* A task-admission envelope is created from a server-normalized request.
-* The envelope is authorized either by an already-valid OwnerDelegationEpoch
-  or by an Owner signature verified by an injected trust backend.
-* The derived TaskAdmissionGrant can only narrow the parent authorization.
-* The grant is handed to the existing Agent Task control plane through an
-  injected TaskAdmissionPort. This module never writes the Task database.
-* TaskPrincipal issuance remains downstream of a real Task claim/TaskLease.
-* Exact idempotent replay returns the same admitted Task; conflicting reuse is
-  rejected.

+"""Self-healing availability guard for persistent Online Agent workers.
+
+The guard never claims Tasks and never writes Task/Job/Git databases. It only:
+- ensures required worker/executor systemd units are enabled + active;
+- checks worker-owned liveness JSON written by the real poll/heartbeat loop;
+- restarts an active worker only when its liveness is stale;
+- honors an explicit maintenance inhibit file;
+- writes a bounded status JSON under /run for observability.
+
+Idle liveness is the successful poll loop itself. Busy liveness is refreshed by the
+Task lease-heartbeat thread, so long-running Tasks are not mistaken for hung workers.
