Update secret-service.md to reflect the actual alknet-secret implementation:
- Fix dependency names/versions: secp256k1 (not libsecp256k1), version 0.29,
add tokio/irpc-derive/hmac/rand, use workspace refs
- Add SecretServiceActor and CacheConfig to public API
- Add ethereum.rs module to crate structure, fix test_vectors.rs filename
- DerivedKey is move-only (not Clone), matching the stronger security impl
- Update BIP39 pseudocode to actual derive_path_from_seed() API
- Document derive_password_string() convenience method
- Document SecretServiceActor::spawn() in irpc integration model
- Update Unlock variant to target state: { mnemonic, passphrase: Option }
- Add implementation gap note pointing to unlock-passphrase-gap task
Add tasks/integration/phase3/secret-service/unlock-passphrase-gap.md:
- Fix Unlock protocol variant to carry both mnemonic and BIP39 passphrase
- Currently the irpc message only has passphrase: String (used as mnemonic)
- The handle supports both parameters but the protocol can't convey them
