Postgres + pgvector persistence for the [`eros-engine`](https://github.com/etherfunlab/eros-engine) AI companion engine. Uses [`sqlx`](https://crates.io/crates/sqlx) with `runtime-tokio` + `tls-rustls`.

## What's in here

- `chat` — message history per session.
- `memory` — two-layer long-term memory (profile + relationship) with pgvector retrieval.
- `affinity` — persisted six-dimensional relationship state per session.
- `insight` — structured JSONB user profile.
- `persona` — persona instances per user.
- `pool` — `PgPool` construction helpers.

SQL migrations ship inside this crate under [`migrations/`](https://github.com/etherfunlab/eros-engine/tree/main/crates/eros-engine-store/migrations) and can be applied with [`sqlx migrate run --source <path>`](https://docs.rs/sqlx).
