The semantic recognizer built a ruvector-core VectorDB at ":memory:"; under
full-workspace feature unification the file-storage backend is enabled and
":memory:" is an invalid Windows filename (os error 123), panicking via
.expect(). Replace the external index with an exact in-memory cosine k-NN over
the enrolled exemplars (embeddings are L2-normalised, so cosine = dot product).
For HOMECORE's small intent vocabularies this is faster, fully deterministic,
and removes the storage backend + cross-crate feature coupling entirely.
ruvector-core dropped from the crate (only used here). Workspace 3122 passed/0 failed.

Implements the three placeholder paths with real, tested behaviour and an
honest typed result wherever a capability is genuinely data-gated.
homecore-assist:
- runner.rs: add LocalRunner — runs the real IntentRecognizer pipeline and
returns a fully-formed RufloResponse (resolved intent + speech). NoopRunner
is now honest: typed NotStarted before spawn, explicit empty after (never a
silent fabricated response). A live ruflo-agent.js subprocess remains the
data-gated future path.
- recognizer.rs / semantic_recognizer.rs: real SemanticIntentRecognizer — embeds
the utterance (deterministic feature-hash embedding, new embedding.rs) and runs
ruvector-core HNSW nearest-neighbour search over enrolled exemplars, accepting
matches above a configurable cosine-similarity threshold (default 0.75) and
falling back to regex below it. Measured: paraphrase "turn on the kitchen
light" vs exemplar "turn on the light" -> sim 0.855 (match); "schedule a
dentist appointment" -> sim 0.106 (no-match). `semantic` feature on by default.
homecore-recorder:
- db.rs: search_states_by_text — real SQL LIKE query over entity_id/state/attrs
returning real rows (newest-first, k-capped, LIKE-escaped). search_semantic now
falls back to it when the vector index yields no hits, so it is no longer
always-empty under the default NullSemanticIndex.
Tests (real behaviour; each fails on the old always-empty stub, verified):
- homecore-assist: 39 passed / 0 failed
- homecore-recorder (P1, no features): 19 passed / 0 failed
- homecore-recorder (P2, --features ruvector): 25 passed / 0 failed
All files < 500 lines; homecore-server consumer still builds.
