The unified agent gains an availability module: probe assignments
arrive through the signed remote-config channel (missing key clears
the schedule), each enabled target runs on its own clamped interval
through the shared probe core, and results queue in a bounded
drop-oldest buffer. A result is offered to the primary server until
one delivery succeeds and never again after - buffered offline
reports are stripped of availability results so the disk buffer
cannot replay observations the queue still holds. ApplyHostReport
feeds accepted reports into the probe ingestion path, where the
ownership check and failure accounting live, and the probe agent id
is projected onto unified availability resources for source
attribution in the UI.

Availability targets gain an optional probe agent assignment. Setting
it requires the external_probe entitlement, enforced only at the
moment of assignment - local targets never consult the license path.
Assigned targets are delivered to their agent through the signed
agent-config channel, skipped by the local poller, and resume local
execution automatically if the entitlement lapses. Probe-reported
results are accepted only from the currently assigned agent, share
the local failure-threshold accounting, carry source attribution,
and derive to indeterminate at read time when reports go stale.
