Re-reviewed all commits up to 2861200. This review covers the full audit module implementation including the latest changes since the previous review (1d3fe79).

Key changes reviewed in this pass:

• Complete audit module: keeper, ABCI hooks, epoch math, enforcement, evidence system, pruning, genesis, queries
• Epoch-based architecture with deterministic peer assignment (seed-based offset + round-robin with self-exclusion)
• XOR-distance-based challenger selection for storage challenges using blake3 hashing
• Evidence types: ACTION_EXPIRED, ACTION_FINALIZATION_SIGNATURE_FAILURE, ACTION_FINALIZATION_NOT_IN_TOP_10, STORAGE_CHALLENGE_FAILURE, CASCADE_CLIENT_FAILURE
• Per-epoch params snapshots for mid-epoch governance stability
• Supernode enforcement: postponement for missing reports, host metric violations, peer port failures, action finalization evidence; recovery with separate action-finalization recovery path
• Action module integration recording finalization evidence via audit keeper interface
• Upgrade handler (v1.11.0) with dynamic epoch_zero_height and immediate epoch-0 anchor creation
• Adaptive store upgrade manager for devnet environments
• SDK upgrades (Cosmos SDK v0.53.5, CometBFT v0.38.20, wasmd v0.61.6), removal of x/crisis module
• Params immutability enforcement for epoch_length_blocks and epoch_zero_height

Summary:

• No issues found

Thorough re-review of the full audit module implementation. Code is well-structured, follows Cosmos SDK conventions, and includes proper defensive programming throughout. Epoch math, enforcement logic, evidence system, pruning, genesis handling, upgrade handler, and action module integration all look solid. No issues found.
