# Phase Sponsorship

**What the payer receives:** no direct product access at all in the
minimal case — this profile is for financial support explicitly directed
at funding a named Phase's development, structurally closer to a grant or
sponsorship than a purchase.

**Worked narrative:** a foundation, a downstream adopter, or an interested
party wants to fund a specific Phase's completion without necessarily
receiving a Commercial Entitlement themselves (though nothing prevents
combining this with one). Because there is no natural default split (unlike
a hosting fee, a sponsorship payment has no "cost" component to separate
from "development" component), the sponsoring party and Licensor must
explicitly declare what fraction of the sponsorship is development
allocation at the time it's recorded. **Unrestricted general project
sponsorship — support for the project as a whole, not any one Phase — is
never assigned to a Phase by default**, since assigning it silently would
let a Licensor manufacture Development Credit for a struggling Phase by
recharacterizing general goodwill funding after the fact.

**Default `development_allocation`:** explicitly declared per transaction,
no numeric default.
