Walkthrough

resolve_to_key now returns BLS, Secp256k1, and Delegated addresses directly. Other address types keep the existing cache and deterministic resolution flow.

Changes

Address resolution

Layer / File(s)	Summary
Direct address bypass `src/message_pool/msgpool/msg_pool.rs`	`resolve_to_key` returns BLS, Secp256k1, and Delegated addresses without consulting the cache or provider. Other address types retain the existing resolution flow.

Estimated code review effort: 1 (Trivial) | ~5 minutes

Merge Risk: ⚪ Minimal · up to b22d5

This localized fast-path change returns known addresses earlier, with no supplied evidence of a concrete production or correctness risk. No actionable merge-blocking risk remains after normal checks and review.

Verify regression coverage for all direct protocols.

The changed branch defines behavior for Protocol::BLS, Protocol::Secp256k1, and Protocol::Delegated. The supplied tests show only the ID-address resolution path. If equivalent tests do not exist elsewhere, add coverage that verifies each direct address is returned unchanged and does not trigger provider resolution or key-cache insertion.
