Marsh Point
A real live site, Marsh Point, scored 75 out of 100, which on a normal scorecard reads as a strong candidate, "Investment Candidate" territory. But the platform’s hard-stop layer flagged the power position as genuinely unbuildable, not just risky, invisible below the fold of the headline number, and that flag sits above the score, not buried in a footnote.
Without that layer, the headline number alone would have said "worth pursuing." Instead the recommendation was forced down to "Hold, constraint." That is not a hypothetical selling point. It is a documented, dated correction the system made to its own optimistic number.
Why a hard-stop existing at all is the proof
Marsh Point is the concrete example, but the pattern is the actual proof, and it holds independent of any one anecdote. Any scoring system that only ever produces one number is making a silent bet that every input matters the same amount, all the time. That bet is false: a site can be excellent on six measures and fatally blocked on a seventh, and if the seventh is buried inside an averaged score, the average can still look attractive. A hard-stop layer exists specifically to refuse that average when one input is disqualifying, regardless of how good the rest of the picture looks. The fact that Lumeyrie has such a layer at all, before any specific example, is what a sceptical reader should notice first: the system was built expecting to be wrong sometimes on a single number, and designed a check for exactly that failure mode.
Two numbers, not one
"How good does this site look" and "how much of that judgment rests on measured evidence" are two different statements, and Lumeyrie never collapses them into one label. A report says something like "72/100, 5 measured, 1 inferred, 1 not assessed; 78% of weight measured," not just "72/100, high confidence."
