Covers the public cache surface against real Postgres and a real local file backend (no mocks): recall miss, remember->recall vector/text/order round-trip, the dimension-mismatch refusal, the repository SQL behind eviction and dedup (size sum, coldest ordering, TTL cutoff, duplicate-key no-op, reuse counter), and the blob store save/load round-trip and delete.

"""Real-infra fixtures for the embedding-cache integration tests.
|
|
|
|
``cache_local_storage`` points the shared cache backend at a throwaway directory
|
|
so tests exercise the real ``LocalFileBackend`` (no cloud, no mocks); the
|
|
embedding cache reuses the ETL cache backend, hence the ``ETL_CACHE_STORAGE_*``
|
|
knobs. ``clean_embedding_cache_table`` removes rows written through the store's
|
|
own committing session, which the savepoint-rolled-back ``db_session`` cannot undo.
