Live PBS runbook surfaced two gaps: (1) PBS verify defaults to ignore-verified=true and
SKIPS already-verified snapshots, so corruption after the first verify is never caught —
the agent's integrity check now POSTs ignore-verified=false to actually re-read+re-check.
(2) restore-test source_tier was hardcoded 'local'; now derived from the source storage
type ('pbs' for a PBS datastore). Adds a form-POST path to the PBS client.
