Struct ContextDiff 

#[non_exhaustive]
pub struct ContextDiff {
    pub added: Vec<ContextBlock>,
    pub removed: Vec<NodeRef>,
    pub kept: Vec<NodeRef>,
    pub tokens_estimated_added: u32,
}

Plan 15: result of Memory::build_context_diff.

Splits the post-budget block list into the parts that changed (added), dropped (removed), and survived (kept) since the supplied snapshot. Chat-style turn loops can re-emit only added to the LLM; kept carries anchors with no body so callers know which blocks the prior turn already saw.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

added: Vec<ContextBlock>

Blocks present now but absent at the snapshot.

removed: Vec<NodeRef>

Anchors of blocks present at the snapshot but absent now.

kept: Vec<NodeRef>

Anchors of blocks present in both — body intentionally omitted so callers don’t double-send.

tokens_estimated_added: u32

Cheap upper bound on the additional tokens the caller now needs to budget for, summed over added.
