Wire real probes: port_owner_description reads the kernel socket table and attributes non-loopback (foreign/compose) listeners; last_backup_at converts state.last_backup_at (ISO) to epoch; tls_expiry parses the data-dir tls/ cert notAfter via cryptography. - logs --rotate now refuses while the launcher is running (rotate_log requires no appending fd; otherwise post-rename writes land in the rotated-away inode). - _state_problem_kind now classifies a missing state.json (secrets present) as 'missing' (uninitialized) instead of the misleading 'corrupt' language; it distinguishes "No such file" from a torn/garbage file. - _host_port_from_database_url degrades an out-of-range ambient DATABASE_URL port (e.g. 99999) to an honest ('unknown', None) skip instead of crashing the settings-source check. - doctor --report now tees the doctor output to stdout so the operator still sees the check table, and doctor_report seeds percent-encoded credential values into the redaction map so credentials embedded in URLs are scrubbed.

Moved the rotate call inside the app-only else-branch so child components print the message and return without rotating. 2. supervisor.py `_record_runtime_locked`: nothing ever persisted `installed_bundle_pg_version` into the runtime manifest (extra=None wiped it on every write), so doctor's check_bundle_versions downgrade/upgrade axis was a no-op in production. Resolve the bundled postgres version once at boot and merge it into the manifest's extra on every write (alongside degraded_reason), so the axis now fires against the last-run cluster version.
