Module conformance 

Shared behavioral checks for MemoryProvider implementations.

Backend crates should call these helpers from integration tests so every persistence layer honors the same contract. See cel-memory-sqlite/tests/swap.rs for a downstream example.

Functions

assert_retrieve_finds_written

Hybrid retrieval must surface a chunk the provider just wrote.

assert_session_lifecycle

Session open → scoped write → close must round-trip through get_session.

assert_summarize_session_roundtrip

Summarization must produce a persisted JobSummary linked to the session.

assert_write_get_stats

Minimal contract every backend must satisfy: write a chunk, read it back, and report coherent stats.
