Check an evidence package without the model that made it
Every export carries a provenance manifest that hashes each file and records how each result was derived. e2er verify re-establishes offline, without an API key, that the package is internally consistent and untampered.

$ select a package to verify Check a package in your browser
Choose an exported package folder. The browser recomputes the SHA-256 of every file listed in its provenance.json. Nothing is uploaded.
The browser checks integrity only. Numbers, tables, the estimation specification and citations need e2er verify, which recomputes them from the package's result files.
pip install e2er && e2er verify <bundle>What each check establishes
| Check | Establishes |
|---|---|
| integrity | Every file matches the hash recorded in provenance.json at export |
| numbers | Table cells trace to values in the executed code's result files |
| tables | Tables reproduce byte for byte from their result files |
| spec | The estimation implements the identification declared before it ran |
| citations | Every cite key resolves in the bibliography; the run-time verification is kept as a snapshot |
