turn_admission_stage

The erase-admission stage of raw PostgreSQL v1 memory composed without a history.

A NativeConversationHistory captures the turn's admission in its own admission stage. Memory composed alone has no such stage, yet its turns read memory and write it back, so memory_capabilities adds this one: it runs before retrieval and captures what the writer later presents (CORE-199 P3-4).

MemoryTurnAdmission 

MemoryTurnAdmission(generations: Any, path: str)

Capture the turn's erase admission for one composed scope.
