Struct CacheMeta 

pub struct CacheMeta {
    pub boundaries: Vec<CacheBoundaryMeta>,
    pub tools_prefix: Option<PrefixMeta>,
    pub system_prefix: Option<PrefixMeta>,
    pub history_tail: Option<PrefixMeta>,
    pub delta: Option<CacheSegmentDelta>,
}

Cache boundaries, stable-prefix digests, and previous-turn segment deltas (spec §6.6). The prefix/tail digests are keyed HMAC over canonical component bytes (see trace::diagnostics for the exact canonicalization and its documented approximations) — never a re-serialization passed off as exact wire bytes. All diagnostic fields are optional for backward-compatible deserialization.

Fields

boundaries: Vec<CacheBoundaryMeta>

tools_prefix: Option<PrefixMeta>

system_prefix: Option<PrefixMeta>

history_tail: Option<PrefixMeta>

History tail: the canonical bytes of the messages after the last message-level cache boundary (the segment the provider recomputes).

delta: Option<CacheSegmentDelta>

Previous-turn per-segment comparison, when a session snapshot was available to compare against.
