One row per real room, not one per supplier spelling
Suppliers describe the same hotel room in dozens of ways. The Plexe mapper (production + safety layer + price guard) keeps Plexe production's grouping, splits off listings whose wording points to a different room, and places vague names at the lowest grade unless prices say otherwise. It never merges groups.
How it works
1Start from Plexe production's room groups (July to August 2026).
2Read each supplier name against the hotel's room list: an exact match, the only room that fits, a word that singles out one room, or an AI reader quoting the name.
3Split off any listing whose wording points to a different room than the rest of its group. Nothing is ever merged.
4Price guard: a name that does not say its grade goes to the lowest grade, unless prices show it belongs higher.
