Struct ExportedFact 

pub struct ExportedFact {
    pub id: u32,
    pub text: String,
    pub entity: Option<String>,
    pub tags: Vec<String>,
    pub metadata: BTreeMap<String, String>,
    pub recorded_at: u64,
    pub valid_from: u64,
}

One exported fact — the human-readable, id-free shape Database::export dumps and an importer re-remembers. Internal ids and recorded_at are the engine’s bookkeeping and are not preserved across a round-trip; the knowledge itself (text, subject name, tags, validity start) is.

Fields

id: u32

The fact’s id in the database it came from.

Informational, and deliberately not restored on import: a fresh database assigns its own. It is here because edges reference their provenance fact by id, so a dump that carries edges needs something for them to point at — an importer translates old id to new as it goes.

text: String

The fact text.

entity: Option<String>

Subject entity name, if the fact had one.

tags: Vec<String>

Tag strings.

metadata: BTreeMap<String, String>

Metadata as a sorted key→value map (empty when none) — preserved on import.

recorded_at: u64

When the memory learned it (informational; not restorable on import).

valid_from: u64

Validity start — preserved on import.
