August 2025 focused on strengthening test reliability and CPU emulation accuracy in a16z/jolt. Delivered new Test Fixtures Regeneration Documentation to standardize how to regenerate test fixtures when the prover or verifier changes, including a two-step workflow (build via cargo and copy output) to streamline developer onboarding and regression testing. Implemented a bug fix for cycle marker ID length handling, ensuring the length is correctly passed to ECALL and that the CPU emulator tracks cycles accurately for longer marker IDs, improving the accuracy of cycle accounting and debugging. These contributions reduce maintenance overhead, speed up test setup for new prover/verifier changes, and enhance emulator reliability.
