as_of accompanies every one of them on every door.
The names, types and availability below are fixed. No read interface or MCP tool serves them yet — this page publishes the shape ahead of the doors.

Availability
✓ available by default · ⊕ available after an opt-in that states who becomes able to see the value · — not available.
No value on this object is published on the events door. Beacon publishes no event catalogue.
cost_to_serve_amount is a money value. It is stated in your single reporting currency, and every read of it is recorded in the access log. cost_to_serve is a ratio of two figures in that currency, so it carries no currency of its own.
fit_score and customer_value are modelled composites, so they land in your CRM as bands — beacon_fit_band and beacon_customer_value_band — while the exact fit_score stays on the read interface and MCP tools, where the model version and the as-of travel with it.
Freshness
A correction arriving after a seal is recorded as a named adjustment in the current period. A sealed figure is never quietly restated.
