Prove the release offline

The fixture is the fastest honest proof that an installed binary can process and verify data. It uses deterministic blocks but runs the production storage, processor, change-delivery, coverage, checkpoint, and integrity paths.

Exercise the installed binary without an Ethereum provider.Verified source
  1. Use a new data directory; the fixture refuses to overwrite an existing one.
  2. Inspect the JSON report for status: "passed", continuous coverage, the expected change count, and databaseVerified: true.
  3. Keep the report with the version and checksum you tested.
  4. When using this diagnostic path, move to a bounded Mainnet range after the local proof passes.
