Summary

Exposes authenticator management operations in WalletKit, enabling users to register, update, and remove authenticators on their World ID account.

Implementation still uses pure delegation to world-id-core for authenticator operations — WalletKit handles FFI type conversion (compressed pubkey bytes → EdDSAPublicKey, hex string → Address) and returns FFI-friendly types.

Dependency

This PR now targets the world-id-core 0.7.0 API.

Because world-id-core = "0.7.0" is not yet available on crates.io at the time of this update, WalletKit is temporarily pinned to the merged upstream world-id-protocol revision that contains PR #603:

  • world-id-core = { git = "https://github.com/worldcoin/world-id-protocol", rev = "8174a6a938b569005cd42ab22baa0c25091a3935", default-features = false }

Once 0.7.0 is published, this can be switched back to the crates.io release.

Upstream API changes handled here

  • insert_authenticator, update_authenticator, and remove_authenticator now return GatewayRequestId instead of String
  • GatewayRequestId is an explicit newtype with Display, but no From<String> / Into<String> conversion
  • Authenticator::poll_status(&self, request_id: &GatewayRequestId) is available upstream for polling operation state

WalletKit adaptation

  • WalletKit FFI still returns String, so the returned GatewayRequestId is converted with .to_string() in:
    • insert_authenticator
    • update_authenticator
    • remove_authenticator
  • poll_operation_status(request_id: String) remains a direct gateway HTTP call in WalletKit, which already works with the prefixed gw_... request ID string and avoids extra conversion requirements on the FFI boundary
  • Credential compatibility was updated for the upstream rename from associated_data_hash to associated_data_commitment while keeping the existing WalletKit accessor stable

Changes

File Change
Cargo.toml Switched world-id-core to the upstream git revision containing the 0.7.0 API changes
Cargo.lock Updated lockfile for the upstream dependency graph
walletkit-core/src/authenticator/mod.rs Converted returned GatewayRequestId values to String for FFI
walletkit-core/src/credential.rs Adapted to upstream associated_data_commitment field while preserving WalletKit’s associated_data_hash() accessor

Testing

  • cargo build -p walletkit-core
  • cargo test -p walletkit-core --lib
  • cargo fmt --all

Note

Medium Risk
Adds new gateway-backed authenticator management APIs and request-id polling on the FFI surface, plus bumps world-id-core and related crypto deps; behavioral correctness depends on upstream semantics and proper pubkey/address parsing.

Overview
Exposes authenticator management through the WalletKit FFI by adding Authenticator::insert_authenticator, update_authenticator, remove_authenticator, and poll_operation_status, delegating to world-id-core while converting FFI-friendly inputs (hex Address strings and 32-byte compressed EdDSAPublicKey bytes) and returning request IDs as String.

Updates dependencies to world-id-core 0.7 (and lockfile bumps around taceo-oprf*) and adapts to upstream API/field changes, including renaming the credential accessor to associated_data_commitment and updating the integration test to import OprfKeyId from world-id-core. Adds unit tests covering compressed pubkey parsing and restructures storage-dependent tests into a separate module.

Rebased and force-pushed. Here's what was resolved:

  • Dependency conflict: branch was pointing to a git ref for world-id-core; main had moved to the published v0.6. Resolved in favour of main's version across Cargo.toml, Cargo.lock, and a trivial whitespace conflict in error.rs.
  • CI fix: 4 type errors from missing & borrows on StoragePaths in test calls — fixed in authenticator/mod.rs.

All checks clean locally: cargo buildcargo clippycargo fmtcargo test (80/80) ✅

…letKit

Add methods to the WalletKit Authenticator for managing authenticators
on a World ID account, matching the world-id-protocol's authenticator
management capabilities:

- insert_authenticator: Add a new authenticator to the account
- update_authenticator: Replace an existing authenticator at a slot
- remove_authenticator: Remove an authenticator from a slot
- poll_operation_status: Track gateway operation finalization

Implementation uses pure delegation to CoreAuthenticator's management
methods (now &self in world-id-core 0.5.3). WalletKit only handles
FFI type conversion (compressed pubkey bytes -> EdDSAPublicKey,
hex string -> Address).

Depends on: worldcoin/world-id-protocol#564 (0.5.3)

Tests:
- Unit tests for pubkey parsing helper (valid, invalid, roundtrip)
- Integration tests for poll_operation_status (success + error)
- All existing tests pass (82 total)
- Replace git branch reference (fix/authenticator-management-self-ref)
  with the published crate: world-id-core = { version = "0.5.4", default-features = false }
- world-id-authenticator, world-id-primitives, world-id-proof all
  updated to 0.5.4 in Cargo.lock accordingly
- Fix test signal field: Option<String> → Option<Vec<u8>> per updated API

Verified: cargo build + cargo clippy pass clean; 82/82 unit tests pass
(test_authenticator_integration requires anvil binary — pre-existing env gap)

hmm I think this could cause a broken state, and as I think more about it, it may not be a problem with walletkit but with the protocol crate. inserting/updating/removing an authenticator alters the packed_account_data. this is saved in the CoreAuthenticator so certain subsequent operations will fail with hard to debug bugs

Update world-id-core (and transitive world-id-* crates) from 0.6 to 0.7.

Code adaptations for the new API:
- credential.rs: rename associated_data_hash → associated_data_commitment
- proof_generation_integration.rs: OprfKeyId re-exported from world_id_core::primitives

Extracted from #306.
