# ---- Plain text part ----
plain = """ITPP Phase One Infrastructure Audit - Final Package

Phase One read-only audit is complete across all six servers plus the Gitea
estate, DNS, and backups. Zero live changes were made.

What we found (five systemic themes):
1. No segmentation - Docker published-port rules bypass UFW, roughly 20
   management consoles public, no VLAN or Tailscale ACLs.
2. Plaintext credentials in world-readable locations across the estate.
3. Backups are write-only - 30 of 34 targets backed up, only 2 ever
   restore-tested; LiteLLM Postgres never backed up.
4. SIEM monitors only itself - Wazuh has zero enrolled agents; Grafana
   default admin/admin public, no MFA.
5. Warm standby not data-ready - app1-bu state.db roughly 28 days stale.

Severity: 23 Critical, 34 High, 36 Medium, 17 Low (consolidated).

Independent review (Indep, claude-sonnet-5): re-scored every Critical/High.
Confirmed D1 (watchdog IP) false positive. Refined D2 (Gitea dropped from the
finding, has a passing restore test). Caught two silent downgrades now
restored (single SSH key restored to Critical as C10) and one missed finding
(WISP tower router zero backup).

Attached: report.md, policy-and-procedure.md, skill-spec.md, indep-review.md.

Next step: Phase Two remediation is ordered in Section 4 of the report. The
highest-leverage first moves are bind Docker publishes to loopback, rotate
plaintext credentials, and enroll Wazuh agents. No action taken in Phase One.
