Ferro Index™ · The Register
The Sanctuary Register
The hotels that clear 85. True luxury, with name and reasoning, told by someone who was there.
Nomination received. Every verdict goes through a human check: if it holds, you'll find it here.
The rule
Only excellence gets named here
A hotel enters the Register only when a real guest measures it above 85 with the Ferro Index, submits it with name and reasoning, and the nomination passes a human check. It cannot be bought, it cannot be requested: it has to be earned.
The blue check next to an entry means I've seen proof of the stay, an invoice or final bill, and read the nomination before publishing it. It doesn't mean I've checked the facts the guest reports.
Scores under 85 never appear with a name. The Register exists to point at true luxury, not to expose whoever falls short: that part stays anonymous.
The band is rare by design, as in the professional systems, where the top threshold is reached only by holding everything together at once. A short Register is a Register that means something.
