Log a refused wording without what it quotes, and keep the secret-given words within bounds

The reviewer found that the logged reason quoted the refused fragment: a
hash-shaped secret would reach the journal, and a changing clock time
defeated the once-per-kind dedupe. The reason is now logged without its
quoted fragment, the test resets the dedupe so it repeats, and a module
name too long for the headline falls back to the machine.
