Hey, there is something in there that specifically speaks to what you're looking for Taran.
That sequence of events is equivalent in effect to the player assessing the existence of the aspect and then making use of the aspect that results.
Or equivalent to the player undertaking a maneuver to weaken the boards in the floor and then making use of the aspect that results.
That's the "secret" of assessment, declaration, and maneuvering, in fact -- they're all the same action, in essence, a skill roll that gives rise to an aspect, which offers a free tag out of respect to the successfully made skill roll. The only difference between them is in terms of how the authority model appears to work. Assessment is a discovery of something the GM thought of, uncovered by a successful skill roll. Declaration is the establishment of a player-invented reality, backed by a successful skill roll. A maneuver is a character-imposed change in circumstance, successfully established if the player makes a (often contested) skill roll. But outside of those authority models, it's the same basic game move.
And of note Haru, I couldn't find that example either, but I did bump into this when looking in a section about declarations.
Or imagine that you use Lore to declare that
the magical cult your group is seeking assistance
from appreciates direct displays of strength as
part of their customs.
Seems like a declaration about the attitude or aspect of another person/group of people.
