Every clone-fidelity gate compares properties of NAMED selectors, so none of them can see an element
that exists on only one side; regions found an extra control and an invented chart by eye, past eight
green gates. This executes the Driver's binary scope test (promoted from regions' probe).
- Harvests every visible text node through every shadow root on both sides and diffs the sets:
OURS-ONLY unaccounted (scope violation) and THEIRS-ONLY (omission) fail; SANCTIONED entries must
carry the Driver's words, date and card or the preset is refused; same-label digit drift is
reported, not failed.
- The negative control is mandatory: a known ours-only string must land in the ours-only set, or the
run prints CENSUS IS BLIND and exits 75. An unreachable live page is also 75.
- Presets live in internal/element-census/<name>.json; ad hoc via --leaf/--live/--neg.
- Measured: regions passes (list 229 vs 228, the only difference its sanctioned poster toggle; Africa
97 vs 97 with 3 live-vs-snapshot figures). With the allowlist removed the toggle FAILS as
unaccounted; a negative-control string not on the page gives CENSUS IS BLIND, exit 75.
