## Gas Reports You can run `./bootstrap.sh gas_report` to generate a detailed gas report for the current state and update the gas_report.md file. When running CI or tests with `./bootstrap.sh test`, the script will automatically check if gas usage has changed by running `./bootstrap.sh gas_report check`. If gas usage has changed, the test will fail and show a diff of the changes. If the changes in gas usage are expected and desired: 1. Review the diff shown in the output 2. Run `./bootstrap.sh gas_report` to update the gas report file 3. Commit the updated gas_report.md file NOTE: Our gas reporting excludes certain tests due to Forge limitations: - FeeRollupTest and MinimalFeeModelTest test suites are excluded - testInvalidBlobHash and testInvalidBlobProof test cases are excluded This is related to [this Foundry issue](foundry-rs/foundry#10074). This means that we don't report gas for blob validation (currently 50k gas per blob, and we use 3 blobs per propose in production). If you want to run gas reports directly with `forge`, you must use the environment variable `FORGE_GAS_REPORT=true` instead of the `--gas-report` flag. The `./bootstrap.sh gas_report` command does this for you automatically.
