The missing-buyer diagnosis is a negative existence claim: for this named offer and this receiving system, no connected owner-authority path. The falsifier is finding one. Those two are not symmetric.
The page correctly refuses silence and rejection as proof. What it does not specify is the search that would license the negative. Most organizations contain seats that can, under some redescription, own a slice of the problem. Without a stopping rule for that census, “missing” is the name you give after you stop looking.
The lazy version is already forbidden. The sender has to name the offer and the receiving system; enlarging the offer until nobody owns the complete problem is how the diagnosis becomes a shield. A buying center still counts. Owner and authority may sit in different seats if an actual decision process connects them.
So the negative is not “no one here would benefit.” It is “no connected process both owns this problem and can authorize this change.” That is a finite claim once offer and system stay named.
Finite is not checkable. The residual is the enumeration rule: which roles enter the candidate set, what counts as a connecting process, and when a disconnected pair is latent rather than missing.
A usable procedure would list every seat that could own the problem or authorize the change, then record whether a standing path joins any owner to any authority for this offer. Empty join: missing. Nonempty join with a hole in budget, category, evaluation, or sponsorship: latent. Short of that census, the table is still a vibes classification.
