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
- Add irpc (0.16) and irpc-derive (0.16) as workspace dependencies
- Add irpc, irpc-derive, and secp256k1 (optional) to alknet-secret Cargo.toml
- Clarify encryption-salt-kdf task: Option B (document salt as reserved) is the
chosen path per spec update, removing Option A acceptance criteria
- Update irpc-secret-protocol-integration task with concrete irpc crate details:
real crate on crates.io v0.16, #[rpc_requests] macro, workspace config,
AuthProtocol pattern reference, DerivedKey serialization considerations
- Fix secp256k1-ethereum-derivation task: correct crate name is secp256k1
(not libsecp256k1), add version pin 0.29
9 atomic tasks for alknet-secret spec conformance and gap closure,
derived from architect's implementation review. Dependencies form
a 5-generation graph starting with spec update, then parallel
implementation tasks, ending with a review gate.
Tasks address: DerivedKey zeroize security, key caching with TTL,
irpc protocol integration, password derivation, secp256k1/Ethereum
derivation, encryption salt/KDF, crypto test vectors, and final
spec conformance review.
