fix(bookspec): the schema refuses a key only its query may name (P13)

`accepted` and `refused` are a command's (and `refused` a period's): the
schema now refuses either on a query that does not take it, as the loader
already did, instead of letting a malformed example reach the runner.
The no-op table walk in the same branch goes with it.
