kb: five facts from PR #82, and the negative arm's own anti-vacuity guard

Browse Source

PR #82 disproved the replacement claim this orchestrator had handed its
author, not only the original: of the four prepare steps documented as
"the reason the test is not vacuous", only DeleteView and ShowItem are.
ToggleGroup::apply toggles collapse unconditionally — the membership check
gates only reset_cursor — and TransposeAxes' step restates a precondition
View::on_category_added already establishes. Verified against the source
before recording.

Also records the detector half of the N-1-guarded-edits shape, named by
the PR #79 reviewer: a comment explaining why something is correct is weak
evidence that anything checks it, and the more carefully argued the
comment, the more likely it is standing in for a test. Five instances
across two independent reviews.

The two new keys are dated slugs rather than improvise- ids, because bd
issued none. An ID-shaped non-ID is worse than a dead id: the diagnosis is
identical and the repair is not.
