Recover complete history locally with `git clone evidence/briefcheck-history.bundle .work/briefcheck-history` or the corresponding accessproof bundle. Bundles contain only already-public, owned project history. In the restored BriefCheck repository, `node tests/benchmark.cjs <commit>` runs the current frozen harness against that historic core. The included script automates this without relying on the monorepo's unrelated commit layout.

The AccessProof browser runner is in `projects/accessproof/tests.html`. Historic 12-case and expanded results were measured in Chromium and are documented in its VERIFICATION.md and ITERATIONS.md. axe-core was test-only, not bundled at runtime.
