Module engine 

The memory engine facade.

MemoryEngine owns everything that outlives a conversation — the repository, the compiled index, the event log, the extractor seams — and MemorySession owns everything that does not: the candidate ledger, the overlay, the turn counter, and the prepared snapshot the current turn is being answered from.

The split is the architecture in miniature. A session may end abruptly at any moment; nothing it holds is authoritative until reconciliation writes it through the engine.

Structs
