nx_asset_ingest_real.nx -- R5: POPULATE THE PRODUCTION CATALOG WITH REAL ASSETS. The visible-payoff ingestor: it catalogs a REAL, on-disk asset set (not fixtures) into the production catalog prefix knowledge/store/asset-catalog-, so the R5 dashboard surfaces GENUINE numbers. Two real asset classes are ingested, each as a unified content-addressed asset RECORD: * DOC assets = the LIVE wiki pages (web_assets/*.html), machine-generated (prov_class=machine). * IMAGE assets = the real generated gallery PNGs, REAL width/height from the actual IHDR. The read -> record -> dedup CORES live in nx_asset_ingest_lib (DRY #15) so this populator AND its gate (nx_asset_ingest_real_gate) drive the SAME pipeline. This file = the slug/file list + main(). IDEMPOTENT (#10): cat_ingest_cid dedups by content CID -> a re-run yields CAT_DUP for every present asset and the count does not grow. ADDITIVE (#13). No hardware writes (#26). license_tier: ORIGINAL
