Reproducibility contract

PLAIN ANSWER

The report rebuilds from a locked list of source files. If a source changes or an extra file appears, the build stops.

The analysis reads only the locked release bundle. It never reads changing live data or unlisted working files.

The contract also fixes how records are sorted and written before they are checked. That keeps two correct programs from producing different file fingerprints for the same records. Rankings are generated by code, including ties; they are never typed into the report.
