 **Architecture:** IdentityDB will use a layered architecture: a storage layer based on Kysely + dialect adapters, a domain layer for topics/facts/links, and a service layer that exposes ergonomic high-level APIs for querying and ingesting memory. Schema initialization will be automatic and idempotent. AI-assisted ingestion will be abstracted behind a pluggable extractor interface so callers can use a small LLM or a deterministic extractor without coupling the core package to a specific model provider.

 **Architecture:** Keep the relational core portable across SQLite, PostgreSQL, MySQL, and MariaDB by introducing dedicated extension tables: `topic_relations` for abstract/concrete hierarchy, `topic_aliases` for canonical topic resolution, and `fact_embeddings` for semantic indexing. Expose high-level APIs from `IdentityDB` while preserving DB-agnostic behavior by doing semantic scoring in the application layer first.
