Snowman Merkle Airdrop

Summary

s_claimers is declared in SnowmanAirdrop.sol but never read or written; it serves no purpose.

Impact

Wasted storage (gas) and an indicator of incomplete or missing behaviour (e.g., no on-chain registry of claimers for auditing or post-processing).

Likelihood

Low — harmless by itself but signals a potential missing feature.

Mitigation

Remove s_claimers if not required, or implement its intended use (e.g., push addresses when claims succeed) and add bounds/cleanup to avoid unbounded gas growth.
