nx_connect_datalight.nx -- CONNECT worldwide LOW-BANDWIDTH reach (the last LDS-census MU cell): the data-light wire discipline, MEASURED at the architecture level (integer byte accounting inside the gate; the WhatsApp-MQTT class is the named yardstick -- no live-network H2H is claimed, so the cell flips PRESENT, never PARITY/EXCEEDS). BY CONSTRUCTION properties, each with a measured tooth: - COMPACT ENVELOPE: a text message rides a fixed 34-byte binary header + payload (no per-field text labels). NEG-CONTROL: the verbose labeled envelope (JSON-class) measures >3x our bytes on the same payload. - DELTA SYNC: a client syncs with a since-cursor and receives ONLY newer messages; an up-to-date client pays ~0 payload bytes. NEG-CONTROL: the chatty full-poll model refetches the whole tail every poll -- measured O(N x polls) vs our O(new). - ONE-ROUND-TRIP CATCH-UP: a 100-message backlog drains in a single batched response. - TEXT-FIRST MEDIA: a media message ships an 8-byte content-address REFERENCE inline (the blob fetch is lazy + optional; composes nx_connect_media's content addressing). 100% sovereign, deterministic. license_tier: ORIGINAL expect_exit: 0
