Evidence-backed audit of every secret class against the real tree, prompted
by the 2026-07-30 Coinkite COLDCARD entropy incident.
- No Coldcard-class entropy defect exists: no non-cryptographic PRNG, no
clock-seeded key, no Math.random() in any browser key path
- F-01 (Critical, NOT entropy): seed.generate/seed.restore are unauthenticated,
unrated, and unconditionally overwrite a live node's Ed25519/Nostr/FIPS keys
- F-02 [ARCHY-1] CONFIRMED: mnemonic entropy source is a bip39 transitive
default, not a call-site argument — the exact structural shape of T1
- F-03 (High) [ARCHY-3]: first-boot TLS/SSH regeneration is fail-open and its
completion marker is set even on failure, over a fleet-shared cached rootfs
- ARCHY-2 confirmed good; ARCHY-5 refuted as a present defect (32 | 256)
- Argon2::default() is 19MiB/t=2, not ADR-005's stated 64MB/3
- Corrects the scoping assumption that image-recipe/_archived/ is dead: it is
the live ISO builder, exec'd by build-debian-iso.sh
- Adds a "What we do right" section and an UNVERIFIED on-node checklist
