Struct CacheSegmentDelta 

pub struct CacheSegmentDelta {
    pub tools: Option<SegmentChange>,
    pub system: Option<SegmentChange>,
    pub history_tail: Option<SegmentChange>,
    pub changed_tool_ids: Vec<TraceId>,
    pub tool_order_changed: bool,
    pub estimated_reused_bytes: Option<u64>,
    pub estimated_recomputed_bytes: Option<u64>,
}

Per-segment previous-turn change report plus changed-tool detail and reuse estimates (spec §6.6). Every field is bounded metadata: enums, validated tool IDs, and byte counts — never content. All fields are optional/defaulted so synaps-request-trace/1 records written before this struct existed still deserialize.

Fields

tools: Option<SegmentChange>

system: Option<SegmentChange>

history_tail: Option<SegmentChange>

changed_tool_ids: Vec<TraceId>

Stable IDs of tools whose schema digest changed, or that were added or removed, relative to the previous emitted request.

tool_order_changed: bool

True when the same tool set was sent in a different order — an intentional-looking prefix invalidation.

estimated_reused_bytes: Option<u64>

Estimated bytes the provider can reuse from its cached prefix (sum of unchanged-segment canonical byte lengths). An estimate over canonical component bytes, not provider-internal token accounting.

estimated_recomputed_bytes: Option<u64>

Estimated bytes the provider must recompute (changed/new segments + the history tail when it changed).
