Zone II

The brief

Desk view. What the concierge actually sees.

Returning guest

Ms. Lin Chen/ HK ×2 · Phuket ×1

Founder, fintech. First visit to Sand Hill. Quiet luxury — has been everywhere.

Conversation hooks
  • · Closed Series B last month — congratulate without prying
  • · Prior HK suite scent (sandalwood) — mention if asked
  • · Pescatarian; loved Henry's at HK — Sea by Alexander's noted
Handle with care

Discretion Layer suppressed 3 signals (medical, romantic, financial detail beyond public). Auditable.

Zone III

Actuators

What the system commits to. Action + reasoning.

Room state
19°C · warm dim · sandalwood

because HK stays: thermostat 19°C twice. Late arrival — lighting pre-set wind-down.

Welcome amenity
Frog Hollow heirloom pears + Bay Area honey

because 30 min from property. Pescatarian-safe. Sand Hill native — refuses the cookie-cutter macaron.

Itinerary held
07:00 Windy Hill · 19:00 The Sea by Alexander's

because Morning ritual matches HK spa pattern. Dinner echoes Henry's register.
