nx_feed.nx -- F208: THE AUTONOMOUS BACKLOG FEEDER (2026-07-20). The "growing" in the growing-from-god-graph: turns MEASURED maturity gaps into PROPOSED backlog rows so the backlog grows from evidence, autonomously, with the PM triaging -- the rollup's own autonomy + maturity-measurement domains both name this organ as their next rung. COMPOSES, never re-derives: input = a captured nx_ecosystem_maturity_rollup output (the blessed gap deriver); coverage = the frontier seg-store; output = the feedq- plane, a DERIVED VIEW re-seeded per run (sts_seed whole-snapshot semantics = idempotent and SELF-CLEARING: when coverage lands, the proposal drops off the next run). It NEVER writes the frontier SSOT -- propose, don't pollute; promotion = PM copies a row. argv: <rollup-capture> <frontier-prefix> <feedq-prefix> Coverage rule (v1, honest): extract F-ids (F+digits, up to 4) from each domain's next-rung slug; covered iff EVERY extracted id exists in the frontier store (any status). No ids extractable -> always propose (PM dedups; over-proposal is cheap in a staging plane). Proposed row = frontier 9-col format so promotion is literally a row copy. Weight derived from the maturity gap: ordinal ranks TOY=1 FUNCTIONAL=2 PRODUCTION=3 EXCEED=4 S-CLASS=5, w = FEED_W_BASE + (bar - cur) (rank map is definitional ordinal data, commented not hidden). Report: NX-FEED domains=N parsed / covered=N / proposed=N + one PROPOSE line per row. exit 0 = ran (proposals are data, not failures); 2 = usage/inputs. license_tier: ORIGINAL No hw writes (Rule 26).
