Google hashes the immutable `sub` (not email), email hashes normalized email, wallet hashes checksummed address. A composite `(type, identifier_hash)` index exists in the migration for efficient lookups. + +3. **Independent auth methods** -- the old cross-method email auto-linking has been completely removed. The `findOrCreateUserByIdentifier` function only searches within the same auth method type. An explicit test verifies separate users are created even when the same email is used across Google and email auth methods. + +4. **Self-sovereign recovery path** is structurally complete: privateKey -> HKDF (deriveVaultIpnsKeypair) -> IPNS name -> resolve IPNS -> decrypt vault. The rootIpnsPublicKey has been removed from the vault entity, DTOs, API client, desktop Rust types, and E2E helpers. It is now derived from the private key after decryption. + +5. **TEE republishing compatibility** is confirmed by grep -- zero references to rootIpnsPublicKey exist in the ipns service directory. + +**Note on desktop Rust:** The desktop client's `initialize_vault` still uses random Ed25519 keypair generation (not HKDF-derived). This was out of scope for Phase 12.3.1 (which only required removing rootIpnsPublicKey references from the desktop).
