 `--profile factory|library`, default `library`, as the precheck does:

 The precheck's library profile adds these checks to C2-13a's:
 - The business file, `.history`, `changes.jsonl` and persona files have the modes in design 4, and each
   persona digest matches.
-- `library.sync` fetches her repo read-only, and `library.status` lists R-problems.
