/**
 * gardenfly.selftest.js — the audit's garden engine audits itself.  [Lane B, SPRINT13]
 *
 * Browser-only (skyfx needs `document`), so unlike sweep.selftest.js this is an
 * ASYNC factory: b.test.js awaits it and registers the returned [name, fn]
 * pairs. The flights happen here, once; the tests assert on captured results —
 * the same Suite-cannot-await shape a.test.js's pinned-separation flight uses.
 *
 * What it pins, and why each can fail:
 *
 *  1. TWO HARNESSES, ONE PIN. a.test flies backyard_01's `separation` block
 *     through the RiggingSession shop path; this flies the SAME block through
 *     the audit's own chain (gardenfly: windForSite, direct attach, named
 *     hardware). Both must land on A's ruling — held FULL and winning, bare
 *     losing. If a retune moves the wild night, both go red together and the
 *     argument happens in THREADS, not in a drifted tool.
 *
 *  2. THE VENTURI REACHES THE FLOWN WIND. Three harnesses shipped the same
 *     bug (site_audit SPRINT11, C's bench, D's first harness): the funnel
 *     lives in the SITE def and a harness that doesn't wire it flies an
 *     easier yard than ships. Same synthetic-yard trick as sweep.selftest:
 *     starve gardenfly of the siteDef's venturi and this goes red.
 *
 *  3. The shop has no mystery tier: hardwareByName throws on a stranger
 *     rather than quietly handing back nothing (the setHardware lesson).
