Back-port v5 fix 04a828264 to v6. canReadConfig now accepts
ScopeAgentReport (legacy host-agent:report) in addition to the config/
manage/settings scopes; resolveConfigAgent already restricts a
report-only token to the host it is bound to, so it can only read its
own config. Without this, a v5 agent upgraded to a v6 server while still
holding a report-only token gets HTTP 403 on config fetch and breaks.
Retargets TestHandleConfigMissingConfigScope to monitoring:read and adds
TestHandleConfigAllowsBoundAgentReportScope as a #1254 regression guard.
Keep desired config fingerprints as response metadata derived from the signed command and settings payload.
Use merged agent profile settings when building remote config fingerprints.
Retire runtime/API/UI monitored-system volume enforcement now that infrastructure monitoring is no longer capped.
Keep only legacy metadata scrubbing and purchase-start compatibility for old max_monitored_systems references.
Rename the remaining preview surface to monitored-system impact and make previews explanatory rather than save-blocking.
Update subsystem contracts and RA7 evidence for the caps-retired invariant.
