Crate scone_core

Expand description

Scone core: a local-first episodic + semantic memory engine.

This crate performs no stdout I/O and touches the network only through provider traits. SQLite is the single source of truth (spec §5).

Re-exports§

auth: The single authorization chokepoint (spec invariant I5).
chunker: Structure-aware chunking over immutable episode content.
distill: Lane 2 fact application (spec §6): entity resolution, provenance, contradiction closure.
embed: Embedding providers (spec §9).
index: Derived indexes (spec §5): rebuildable caches over SQLite truth.
llm: LLM providers (spec §9): the semantic lane’s only model dependency.
profile: Two-tier profiles (spec §7 via memory/lessons.md L-11): the predecessor validated the shape — stable identity facts plus recent activity, one cheap call (their “~50ms profiles”; ours is a pair of indexed queries).
rerank: Cross-encoder reranking (spec §7 refinement, 2026-08-27): reads the query and each candidate together, scoring true relevance — the precision lever bi-encoders can’t reach. Opt-in: the model is a sizeable one-time download, so surfaces enable it explicitly.
timeparse: Date references in natural-language queries (E12): “in May 2023”, “on 2023/05/20”, “2023-05-20”. Real memory questions are time-anchored; retrieval that ignores their dates leaves the temporal class on the floor (measured 68% all-evidence, 2026-08-28).
