Deployed bytecode reproducibility

Evidence summary #

Build: Solidity 0.8.15, optimizer_runs=1, via_ir=true (data cache confirmed). The via_ir=true compilation path routes through Yul IR, which can introduce toolchain-specific bytecode variation. Reproducibility theoretically possible with pinned settings but via_ir increases build non-determinism risk. No independent third-party reproducibility confirmation found in public evidence.

Methodology #

Determine whether anyone can independently reproduce the deployed bytecode from the repo and declared build toolchain.
