Seven tests, no production change. Two lanes, one selection: a
`Reach::Place` channel's `fan_out` and a witness over the same place
agree over every root and every speaker, so the two callers of
`under_place` and `unheld` are pinned by behaviour and not only by grep.
`under_place` covers a place itself, covers below it transitively, stops
at its edge, and never reaches a subject with no position — including
under the widest root in the world.
Two patches built so the resolver's candidate model and the apply arm
could disagree, and do not: a witness whose only recipient is a subject
the same patch declares and places, and a witness whose only recipient
is a subject the same patch forgot the fact. Each is refused at one
layer if the layers part; both land.
What a witness hands the narrative lane, pinned at the kernel because
the lane's fixtures are another pass's: exactly one scope component
moves, `knows`, which is the anonymous line, and the row it writes
carries no `spoken_at`, which is the only gate on an attributable
`Overheard` row.
The no-`Told` pin named its knowledge-touching kinds by example; an
exhaustive match now breaks the build when a `ComponentOpKind` is added
without saying whether it touches knowledge.
