Intake To Retrieval Sequence

This sequence shows one item moving from intake through promotion, indexing, retrieval, and evaluation, including the review gate that can send it back.

Reading The Sequence

The important branch is the validation gate. An item that arrives without source references or required metadata never reaches the index. It returns to the promotion service with reasons. Only a passing item becomes searchable and gets compiled into the decision store. The evaluation loop closes back onto the routing and guidance surfaces, so what the system learns from failures improves how future work is classified.
