Data
Every snapshot the exercises run on, frozen and checksummed.
Why these are frozen. Each exercise
pulls from a public source once, writes a dated snapshot, records a checksum,
and never touches the network again. That is what lets a reader in a later
year reproduce a figure printed here, and what lets an instructor tell a wrong
answer from a changed source.

Each lab ends by writing the table of every unit and every statistic it computed, alongside the list of decisions the program made without being asked. Students produce their own by running the lab, and the reference copies sit in the instructor area because the tables carry the values the labs ask students to find.
