• Shortened the package description to the 60-180 character window pana scores against. Search engines truncate anything longer, so the ten points it withheld were pointing at a real defect: the useful half of the sentence was never being shown.

Initial release of the vector layer.

Added #

• Values — VectorRecord, VectorQuery and VectorMatch. Identifiers are caller-supplied, which is what makes re-indexing a changed document replace its chunks instead of duplicating them. Search results omit vectors unless asked for; VectorRecord.hasVector says which you have.
• Filtering — a sealed MetadataFilter hierarchy (equals, notEquals, inValues, greaterThan, lessThan, exists, and, or, not) that every adapter must translate in full, so a new filter kind is a compile error rather than a silently ignored predicate.
• Similarity — SimilarityMetric covering cosine, dot product and Euclidean, all scored higher-is-better so that topK ordering and minScore never invert when the metric changes; plus cosineSimilarity, dotProduct, euclideanDistance and normalise over raw lists.
• Port — VectorStore with upsert, search, get, delete, deleteWhere, count and clear, and VectorStoreOperations supplying upsertAll (batched and cancellable), searchVector, exists, deleteOne and the checkDimensions / checkNamespace guards adapters call.
• In-process store — InMemoryVectorStore, exact by construction, with namespaces, oldest-first eviction under maxRecords, and snapshot / fromJson so an offline-first app embeds once and restores thereafter.
• Qdrant adapter — QdrantVectorStore, including deterministic UUID derivation for identifiers Qdrant will not accept, score-direction conversion for Euclidean collections in both directions, full filter translation, and ensureCollection / dropCollection.
• Composition — EmbeddingIndex binds an embedding model to a store, batching to each side's limit, using the document and query encoders correctly, and refusing a width mismatch at construction rather than after ingestion.
• Decorators — DelegatingVectorStore, ObservableVectorStore (traces, logs and events) and NamespacedVectorStore (a handle that cannot reach another tenant's partition).
• Events — VectorUpsertCompleted, VectorSearchCompleted (carrying requested against returned, the number worth alerting on), VectorDeleteCompleted and VectorOperationFailed.
