What does the evidence pack reproducibility checker produce?
Compare repeated evidence-pack manifests by exact output path, declared SHA-256, output version, source versions, build parameters, generator revision and environment. Identify additions, removals and unexplained output changes.
The working area above runs the supported validator in the browser. It keeps the result inspectable and preserves every unresolved item for responsible review.
What do you need before you start?
- A named owner has defined the task and the organization’s intended use.
- The customer has authority to use every supplied record, source or connection.
- Prepare the result in this browser and resolve visible input errors before exporting.
What information do you enter?
Prepare only the bounded inputs listed below for this validator.
- Earlier build reference (required). Identify the earlier generation, build record and retained manifest.
- Later build reference (required). Use a different generation reference. The tool compares supplied declarations without running a build.
- Approved comparison scope and reviewer (required). Identify the expected pack contents, build method and reviewer. Do not treat declared matching hashes as independent verification of actual files.
