Struct MemoryHit 

pub struct MemoryHit {
    pub score: u32,
    pub memory: bool,
    pub id: i64,
    pub kind: &'static str,
    pub scope: String,

}

A hit in the memory channel: something a session learned, never a graph fact and never a re-derivable one.

Deliberately not a SearchHit, for the reason GeneratedHit is not: a memory record has no node, no provenance and no key, and giving it a NodeSummary would be the first step towards its being treated like one. Unlike either of the other channels, it also carries what the tree thinks of it — MemoryHit::applies and MemoryHit::anchor_state — because a lesson about code that has since moved is worth reading and worth labelling, and returning it unlabelled would be the worse of the two mistakes.

Fields

score: u32

Relevance within the memory channel. Not comparable with a SearchHit::score or a GeneratedHit::score: three channels, three scorers, on purpose.

memory: bool

Always true. A marker a consumer cannot miss or forget to check.

id: i64

The record’s id — its generation, and what roteiro memory forget takes.

kind: &'static str

What kind of knowledge it is (lesson | attempt | …).

scope: String

The namespace it was recorded in. Not a branch label.

anchor: Option<String>

The node key it is anchored to, if any.

anchor_state: &'static str

What that anchor is worth against the current tree (valid | drifted | vanished | unverifiable | unanchored).

applies: bool

Whether this record applies to the tree being searched. A false here is a label, never a reason to have withheld the hit.

evidence: f64

The evidence multiplier the record’s own ranking gave it (base_confidence × anchor_penalty), reported so the channel’s score can be taken apart.

snippet: Option<String>

A bounded, whitespace-collapsed excerpt of the body, on the same terms as SearchHit::snippet.
