nx_video_parity_census.nx -- MECHANICAL carry-over guard (operator 2026-07-04: "make sure we arent building into html and js but that we emit so wherever we embed or use it all functionality is carried over"). The /video ROOM (app.v2.js) and the <nishi-video> EMBED (nishi-video.js bundle) are two shims over the SAME sovereign wasm core; features must be present in BOTH or the embed silently lags the room (the divergence that let the duo-PiP layout ship to the room but not the embed). This census checks each shared FEATURE MARKER in both surfaces: PARITY (both) / ROOM-ONLY / EMBED-ONLY / NEITHER. Any non-PARITY row = a carry-over break to fix. NEG-CONTROL: an impossible marker must be NEITHER (checker has teeth). This is monitoring APPLIED to carry-over -- it runs in the keep-up loop so drift is CAUGHT, not prayed. expect_exit: 0 = all shared features at parity + neg-control fired. license_tier: ORIGINAL
