nx_spec_ingest.nx

nx_spec_ingest.nx -- the SPEC -> BUILDER -> INGEST bridge that was MISSING (operator: "is it being pushed into spec work for the builder and being ingested?" -- it wasn't). When the Monitor/opportunity loop selects a move, this turns it into a SPEC (in-type -> out-type, must verify), hands it to the BUILDER (bc_compose finds the chain), and on success BANKS a capability record by APPENDING it to a sovereign registry file -- automatic ingestion, written by the TEAM via sys_write, not hand-edited by Claude. The self-model is regenerated FROM this registry. license_tier: ORIGINAL Composes nx_builder_compose (the Builder) + nx_loop_monitor (productive -> emit spec).
