The `DeterministicKeyGenerator` helper that pre-seeds + * `DidDht.create` with a fixed ordered set of private JWKs, and + * 2. The exact HD derivation recipe — root seed derivation, the + * `m/44'/0'/1708523827'/0'/{0,1,2}'` account paths for identity, + * signing, and encryption keys, and the mnemonic round-trip. + * + * Because both are copies, if upstream `@enbox/agent` ever changes its + * recipe (for instance, bumps the account index, rotates path + * components, or swaps the Ed25519 HDKey implementation) our local + * code silently diverges and will produce DIDs / keys that cannot be + * reproduced by another consumer of `@enbox/agent`. That would break + * recovery-phrase portability — the 24-word phrase we hand the user + * on first launch would no longer re-derive the same wallet on any + * other `HdIdentityVault` consumer. + * + * What this test pins: + * - A fixed 32-byte wallet secret (hex constant), fed through the same + * BIP-39 round-trip our vault uses. + * - The 24-word BIP-39 mnemonic that entropy produces via `@scure/bip39` + * (catches accidental mnemonic-strength / wordlist drift). + * - The raw 33-byte Ed25519 public keys at the three identity account + * paths, computed independently via `ed25519-keygen/hdkey` (catches + * path drift and any upstream HDKey-lib change). + * - The DID URI produced by `BiometricVault.initialize() → lock() → + * unlock() → getDid()` end-to-end (catches drift in the + * `DeterministicKeyGenerator` predefined-key ordering and in our + * `defaultDidFactory` recipe). + * + * Failure contract: + * If `biometric-vault.ts` is edited (to sync upstream, fix a bug, or + * otherwise) and the edit alters any link in the derivation chain, this + * snapshot fails LOUDLY.
