Module turn_extractor 

Memory as a first-class TurnExtractor.

This is the whole runtime integration. The Live runtime already has an out-of-band extraction pipeline that accumulates transcripts, segments them by turn boundary, fires extractors under a trigger policy, and promotes their fields into governed State. Memory is exactly that shape, so it rides that pipeline instead of running a second one beside it.

The promotion step is what makes memory useful to an application rather than merely present. A remembered fact projected into a State slot is read by everything the platform already has:

• phase.needs(&["user:diet"]) — satisfied from memory, so a returning user is not asked again for something they already said last week;
• phase.requires(&["user:diet"]) — a hard gate a memory can open;
• Flow guards, done(captured(["user:diet"]));
• P::show_state(&["user:diet"]) — the value in the phase instruction;
• watchers and repair, which read the same keys.

Each turn the extractor does three things: ingest the finalized utterance, prepare the next turn’s retrieval snapshot, and project what memory knows into slots.
