In this empty working folder, build a small demonstration of loading knowledge only when it is needed: no network, no accounts,
no real data. Make three knowledge files with made-up filler text (suppliers, returns, prices) and a short index with one line
per file saying when it is needed. Then make a reader that, given a question, opens only the files that fit and reports how many
words it loaded. Give it a second mode that loads everything, the way Spaak works now.

Limits: work only inside this folder; send nothing anywhere.

Show me the word counts for four questions, including one about opening hours, and say in one sentence what the smallest count
tells me.
