Accrue.Entitlements.PurchaseDecision (accrue v1.5.0)

Copy Markdown View Source

Revision-bound, rail-neutral purchase preflight decisions.

The value contains host-renderable decision facts and, only after a durable override, an opaque short-lived capability. It never carries provider evidence or customer identity; the public fields themselves are not mutation authority.
