// allow-test-rule: source-text-is-the-product (see #1867) — the rendered reference doc's taxonomy table IS the runtime contract; this pins its bijection to the code (docs-parity, ADR-456 exception matrix)
// Asserts gsd-core/references/ui-consideration-probe.md keeps its taxonomy id column in
// sync with the source-of-truth UI_TAXONOMY (built .cjs), and that the closed compiled
// taxonomy stays DISJOINT from the open-prose domain-probes.md bank (the mixed-axis boundary,
// ADPT-02). The comparison is on PARSED table ids and PARSED `##` headings, never a raw
// full-text substring match — a reformat that preserves the data does not fail; semantic drift does.
