Horizon Milestone

Create or maintain a milestone — a bounded phase map that defines which invariant bundle to establish through multiple pragma cycles. A milestone is a learning/control point, not a delivery batch.

See The Invariant Threshold for the governing principle. A milestone answers: which invariants are we establishing in this phase, and what acceleration does crossing this threshold unlock? The milestone identifies invariant bundles for this phase; capsule documents remain the authority for invariant wording.
