graflo.architecture.evolution.project

Pure planning for :class:~graflo.architecture.evolution.ops.ProjectManifestOp.

Selector validation and manifest unwrapping live here; the induced-connectivity kernel itself lives at layer 2 in :mod:graflo.architecture.schema.projection so manifest projection and schema context projection cannot drift apart.

compute_projection(manifest, op)

Compute survivor/removal sets without mutating manifest.
