R-284 scoped the factored-rating rule to the creature's entry and left the
defence-stacking rules matching anywhere on the page, so the exemption sentence
and the "Across N creatures that spend defences" count were accepted wherever they
happened to sit. Moving the exemption line out of its section into the redcap's
statblock -- the page silent exactly where a GM reads the stripping advice --
passes at R-284 and fails here; confirmed by running HEAD's copy against the same
tree.
The owning slice is not always the creature's entry. A factored rating belongs to
the creature; the ladder exemption is an answer to the paragraph it sits in and is
generated into "## Shooting at something that moves", so scoping that rule to
"### Redcap" would have failed a correct page. sliceOf now takes a heading at any
level and each rule names the slice that owns its claim.
A renamed section fails by name rather than scoping to nothing, which is the shape
of every guard that passes because it found nothing to check.
