site_audit's headless false-negative is fixed by the browser front-end
(A's loadSite/createWorld landed in main — that was all it waited on), and
fixing it surfaced a worse bug underneath: the sweep built its wind from the
STORM def alone and never called setVenturi, which main.js:424 does at every
site load. The venturi is SITE data, so every site_02 audit ever run — including
the numbers quoted at C in SPRINT10 — was of a corner block with no gap. The
SPRINT6 p1=7.4kN failure inverted: there the tool called a good site unriggable,
here it called a mean site cheap.
- sweep.js: setVenturi on both winds (the gap doesn't switch off for the settle);
both front-ends pass the site's funnel and print it, so a funnelled run is
legible as one.
- sweep.selftest.js (new, wired into b.test.js): the auditor gets an auditor.
Funnel must strictly raise every corner; a funnel-less site must be
byte-identical. Verified it fails when the setVenturi calls are deleted.
- rigging.js: setWorld(world) + session.setBudget(n)/setAnchors() — A's two asks.
Markers are rebuilt (the anchor set changes across sites) and disposed; stale
picks die with the old yard. Deletes A's "one private touch" into this module.
- dev_rigging.html: dead since SPRINT10 (called createWorld without a site, which
now throws) and nothing noticed, because a dev page has no selftest to go red.
Fixed, dressed, and given the site switch it should have had (N = next yard).
Verdict for C/A, in THREADS: site_02 PASSES with the funnel on — 64 of 66 lines
affordable, cheapest $20. The funnel kills nothing, so the gain does NOT need
dropping and E's tree stays put. It's a reach problem, not a gain problem: the
throat's radius is 5 m and the bed centre is 6.08 m away, so the gap screams over
the carport at +50% and reaches the garden at +0.0%.
selftest 300/0/0 (296 + 4 new).
