Preferences & Taste

What you like. The highest-utility, lowest-stakes room, and the one that sells the whole idea.

What is it?​

Food, music, aesthetics, travel style, brands you trust, formats you prefer, how you like information delivered, what you find funny, what you find beautiful. The accumulated record of your taste, which every service on earth currently tries to reverse-engineer by watching you.

Why store it?​

This is the room where the everyday magic happens. Connect the travel sliver and an agent that knows everything about Antigua hands you a customized plan in seconds. A new fashion line drops, you connect your fashion DNA, and you get recommendations matched to who you are: the silhouettes that actually work on you, picked from the new collection in seconds. Connect the dining sliver and a new city's restaurant app is instantly better than the one you trained for years at home. Taste context is why a brand-new service can feel like it has known you forever, and why services without your context will feel generic by comparison: a fresh account is useless precisely because it isn't personalized. You should never have to repeat yourself unnecessarily in life.

What does a service legitimately need?​

The domain sliver, and this room is where slivers come naturally: travel style for the travel agent, palate for the meal service, sonic taste for the music app. Preferences decompose cleanly by domain, which makes the curator's job easy and the leak surface small.

What never leaves home?​

The cross-domain profile. Any single taste is harmless; the complete map of your tastes is a psychographic fingerprint worth real money to people who don't have your interests at heart. The protocol's answer: any one room's shelf can be shared for service, the whole room cannot, and nobody gets to browse.
