Walkthrough

Changes refactor the validation module by removing the entire quorum management system, making the instantlock module private internally, and updating module imports. InstantLockValidator remains publicly exported despite the module reorganization.

Changes

Cohort / File(s)	Summary
Module visibility restructuring dash-spv/src/validation/mod.rs	Made instantlock module private (changed from pub mod to mod); removed pub mod quorum and associated public re-exports for QuorumInfo, QuorumManager, QuorumType; retained public re-export of InstantLockValidator
InstantLockValidator refinements dash-spv/src/validation/instantlock.rs	Removed Default implementation; instantiation now requires explicit InstantLockValidator::new() call
Import path updates dash-spv/src/client/chainlock.rs	Updated InstantLockValidator import path to use module re-export: crate::validation::InstantLockValidator instead of crate::validation::instantlock::InstantLockValidator
Quorum module removal dash-spv/src/validation/quorum.rs	Deleted entire file containing quorum management system, including QuorumType, QuorumInfo, QuorumManager, QuorumStats types, all associated implementations, signature verification logic, caching mechanisms, and related unit tests

Estimated code review effort

🎯 3 (Moderate) | ⏱️ ~22 minutes

• Verify no external crate dependencies or other internal code paths depend on removed quorum types and exports
• Confirm import path refactoring in chainlock.rs resolves correctly with the module re-export structure
• Check for any downstream usage of Default::default() on InstantLockValidator that now requires explicit new() calls
• Ensure deletion of quorum.rs doesn't leave orphaned references or incomplete validation flows

Poem

🐰 A quorum departs, the module grows slim,
InstantLock stands tall, the exports now trim,
Private paths whisper, public ones gleam,
Refactored and tidy, a cleaner regime!

Learning: In the Dash codebase, quorum selection for InstantLock verification uses a bit-shifting operation with (64 - n - 1) to extract n bits starting from the second-highest bit of a 64-bit selection hash. The exact reasoning for the extra "-1" isn't documented, but it matches the original C++ implementation for DIP-24 quorum selection.

🔇 Additional comments (3)

dash-spv/src/client/chainlock.rs (1)

107-107: LGTM - Path update aligns with module reorganization.

The updated import path correctly uses the public re-export from crate::validation instead of accessing the internal instantlock submodule directly. This follows the API surface changes made in validation/mod.rs where the instantlock module became private.

dash-spv/src/validation/mod.rs (2)

3-5: Good encapsulation pattern - private module with selective public exports.

Making the instantlock module private while keeping InstantLockValidator publicly re-exported is a solid design choice that hides implementation details while maintaining a clean public API surface.

---

3-5: Removal of quorum module is safe—no code dependencies found.

Verification confirms that no other code in the codebase references the removed quorum module exports (QuorumInfo, QuorumManager, QuorumType). The only mentions of these types are in comments documenting removed tests. The QuorumInfoResult struct found in rpc-json is unrelated (separate RPC serialization type).
