Audit-ready checklist
=====================

Use this as a working list. Check items only when **evidence exists**
(screenshot, log export, signed policy, ticket). This list is not a
certificate.

A. Scope and data map
---------------------

* Named legal entity and systems in scope (console, Drive, NATS, IPFS, ns1)
* Data-flow diagram: endpoint → HPKE/NATS → cryptree/IPFS
* What is PHI / personal data vs ciphertext vs routing metadata
* Peergos verification chapter attached (:doc:`verification`)

B. Keys and encryption
----------------------

* Customer holds Peergos/Drive keys; not on storage host
* NPE/HPKE endpoint keys in directory; private 0600; no xor content
* Signed Ed25519 config; unsigned rejected; admin-history prev+new+diff
* HSM or documented lab-to-HSM path

C. Access
---------

* Console ``PFC_REQUIRE_AUTH=1``, TOTP; Drive login separate
* Inspect k-of-n; author is not an officer; log-before-reveal
* Joiner / mover / leaver for console users
* Google SSO does **not** unwrap cubes

D. Integrity and backup
-----------------------

* Cube chain append-only JSONL; dual hash
* Hash registry: first SHA-256 and receipt win
* Peergos/IPFS: hash-verified encrypted blocks (restore = re-fetch CIDs)
* Restore test: recover a cube from content-addressed ciphertext without
  plaintext backup tapes

E. Logging
----------

* Inspect audit events
* SM summaries: codes + lookup_id only (no bodies)
* Admin-history cube for config

F. Contracts (counsel)
----------------------

* Written BA / not-a-BA determination for disk, VM, backup, IPFS
* DPA Art. 28 where usernames/logs/IPs are processed
* NATS operator: metadata vs content in the annex
* Peergos component assurance: attach Cure53 2019 + ROS 2024 PDFs
  (public; not your org’s ISO/SOC report)

G. Independent audit of *you*
-----------------------------

* SOC 2 Type I/II engagement **or** ISO 27001 registrar **or** HIPAA
  risk analysis + policies (pick the program you actually need)
* Evidence window (Type II / surveillance) if applicable
