Enum PruneGuarantee 

pub enum PruneGuarantee {
    NeverClobber,
    ConflictFlag,
}

The prune guarantee a binding requests (bundle plan 05-verify-sync-engine, F1). Prune produces deletion proposals surfaced in the sync brief (it never mutates the mem); the guarantee governs how a prune proposal treats a model-side edit that races a source removal.

The guarantee a medium can support is derived from its base-leg retrievability (prune_guarantee_for_medium): a git-backed source can retrieve the base leg for a real three-way merge (Self::NeverClobber); everything else degrades to conflict-flagging (Self::ConflictFlag). Requesting a guarantee the medium cannot support is refused at binding-validation time (never at run time) via CapabilityError::PruneGuaranteeUnsupported.

Variants

NeverClobber

Full never-clobber three-way merge — only where the source base leg is retrievable (git-backed sources). The retrieved base lets the merge tell a model-side edit apart from a clean removal, so a divergence is never silently proposed as a clean delete.

ConflictFlag

Conflict-flag degradation (the default — always supportable): where the base leg is not retrievable, prune presents both sides and never auto-writes over a model-side edit. The decided posture for non-git sources (span-snapshot base legs are out of scope — no current payer).
