about

nx_media_record.nx -- MLIB-003 v1 (CALLOUT-012). The uniform MEDIA RECORD = a PROFILE of the X-CAP-001 meta schema (nx_meta_schema), made CONTENT-ADDRESSED via the canonical CID (nx_canon_cid). Composes proven organs (no rebuild, no parallel substrate): record (modality/cid/origin/gen_modality/source_model/consent/license/attr.codec/dims/phash) -> ms_valid (consent hard line) + ms_roundtrip (lossless, X-CAP-001) -> canon_encode + cid_of -> content fingerprint "nxc1-<64hex>" = the store key lib:<fp>. The fingerprint is DETERMINISTIC (same record -> same fp = dedup/provenance) and CONTENT- SENSITIVE (one byte changes -> different fp = integrity/tamper). Persisting+versioning the record on the seg store (nx_seg_store, time-travel PROVEN by nx_infomgmt_gate) = the wiring slice MLIB-003b. Self-validating gate (MEDIARECGATE) for nx_reconcile. license_tier: ORIGINAL
