- cutover readState: enforce 0600 mode bits only on POSIX (Windows ACLs
govern access; chmod is a no-op there)
- backup activation: skip the read-only-handle fsync on win32; the staged
rename-over-open-WAL tests keep running on the POSIX deployment targets
- test-fixtures: normalize fixture paths to POSIX separators before
comparing with manifest entries
Add central notification channels, rules, queue and delivery logs, fleet
organization groups and tags, device discovery, the device action catalog,
instance module reads, the log centre, connection settings and system
maintenance as native /api/v1 routes backed by the existing secret store,
audit trail and pinned upstream transport.
