Work only in this folder, with made-up data: no network, no real accounts. Build a role card for an agent called Spaak, who reads a
bicycle shop's mail and prepares replies. The card is one plain file with goal, result, rules, forbidden, knowledge (a list of
files, each with a line saying when it is needed), owner and what to do in doubt. Add a few small knowledge files, a check that
refuses to start the role if a field or file is missing, and a tool that turns the card into the assignment Spaak starts with.

Limits: Spaak sends nothing himself and promises no discounts; make the card read-only afterwards.

Prove it: move a knowledge file away and show the refusal, put it back and show it passes, then show me the assignment.
