All write paths (upsert_node, upsert_provenance, delete_node,
rename_node, ingest_units) now hold StoreLock across the full
refresh→check→write cycle. This prevents the race where two
concurrent processes both see a key as "new" and create separate
UUIDs for it.
Adds append_nodes_unlocked() and append_relations_unlocked() for
callers already holding the lock. Adds refresh_nodes() to replay
log tail under lock before deciding create vs update.
Also adds find_duplicates() for detecting existing duplicates
in the log (replays full log, groups live nodes by key).
- Replace `pub use types::*` in store/mod.rs with explicit re-export list
- Make transcript_dedup_key private in agents/enrich.rs (only used internally)
- Inline duplicated projects_dir() helper in agents/knowledge.rs and daemon.rs
Replace all partial_cmp().unwrap() with total_cmp() in spectral.rs
and knowledge.rs — eliminates potential panics on NaN without
changing behavior for normal floats.
Use existing weighted_distance() and eigenvalue_weights() helpers in
nearest_neighbors() and nearest_to_seeds() instead of inlining the
same distance computation.
Move parse_timestamp_to_epoch() from enrich.rs to util.rs — was
duplicated logic, now shared.
Replace O(n²) relation existence check in init_from_markdown() with
a HashSet of (source, target) UUID pairs. With 26K relations this
was scanning linearly for every link in every markdown unit.
poc-daemon (notification routing, idle timer, IRC, Telegram) was already
fully self-contained with no imports from the poc-memory library. Now it's
a proper separate crate with its own Cargo.toml and capnp schema.
poc-memory retains the store, graph, search, neuro, knowledge, and the
jobkit-based memory maintenance daemon (daemon.rs).
