The situation
Week 6 at Northdesk. Leila asks whether Ask can ever show a chunk someone may not read, and how soon a tightened permission takes effect. Gareth asks what Ask says when nothing is found, and what breaks at ten times the corpus.
The running example is golden question G034: t-tallis-u031, an IT employee at Tallis Retail Group, asks "What is the salary range for band C?". Only HR's confidential group and executives may read Tallis's salary bands, so the right answer is "not found".
