SPRINT10 gate 1b. A night is now {storm, site}; the week hands over a yard per
night and night three is the corner block. Nights 1/2/4/5 are the backyard; the
plain-string night form still works and defaults to backyard_01.
site_02_corner_block.json: a smaller 24x16 yard with E's carport as the trap it
was built to be — beam anchors rating_hint 0.22, posts 0.30, both below the
house fascia's 0.35, collateral "carport". The site IS winnable off the honest
anchors (one tree east, four ground posts): I enumerated the honest quads at
authoring time and there are four in-band ones covering the bed, so the carport
is temptation not necessity. Full load audit is Lane B's tools/site_audit.
The carport's beams are keyed work:"bracket" — D's field, the MECHANISM not the
type. A bracket up a bare beam is the one anchor you can't fake from the ground,
so it needs the ladder; keyed on type it would fail open (a carport isn't a
house) and the ladder mechanic would silently vanish, which is exactly the audit
D ran. C's venturi list is in the JSON with two gap coordinates they asked for.
The world is rebuilt on a site change, not re-pointed: createPlayer captures the
world into its ground clamp, collider, ladder and broom (Lane D's modules, no
setters), so a clean rebuild is honest — and a site change only happens at a
forecast, never mid-storm. world.dispose() frees the old yard so nothing leaks.
The re-point of rig + session lives inside loadSiteInto, keyed on the rebuild
itself, after a caller-side version proved fragile.
Verified end to end through real phase transitions: play night 1, hit the
aftermath, and the forecast into night 3 rebuilds into the corner block —
carport present, 10 anchors (cb/cp/q/tr, not h/t/p), smaller bed, player rebuilt,
no scene leak. Then back to the backyard, 12 anchors restored. Selftest 289/0/0.

SPRINT10 gate 1a, carried since Sprint 8. Everything that was a module constant
— bed rect, house line, tree and post placements, shed, gnome, sun angle, fence
sides — is now data/sites/backyard_01.json, and world.js is a builder.
The extraction is byte-identical, and that's checkable rather than claimable:
E's branch-anchor tripwires pin five positions to 6 dp, a.test's quad-band
asserts pin the whole rigging geometry (>=3 quads in 18-45 m2, full coverage
still >45 m2), D's ladder field and B's balance lines all pass unchanged.
287/0/0.
It's byte-identical by construction, not by luck: the site-derived values keep
the builder's original local names, so ~500 lines of geometry that was already
correct is untouched and only its SOURCE changed.
Two things earned their place:
Anchors carry D's `work: "cloth" | "bracket"` — the MECHANISM, not the type. A
post is tensioned from a cleat at its base and a tree strop is thrown, but a
bracket bolted up a bare wall is the one you cannot fake. Keyed on mechanism
because `type` is a closed enum ('house'|'tree'|'post') that site_02's carport
doesn't fit, and needsLadder keyed on type FAILS OPEN there — the ladder
silently vanishes and you re-rig a 2.6 m bracket standing on the grass.
p4's swept position table moved INTO the JSON's `_why`, beside the coordinate it
justifies. That table is the only thing stopping someone nudging the post toward
the bed and collapsing DESIGN.md's central tension; it belongs with the number,
not in a file the number left.
validateSite() fails loud: sites are content, and a missing bed silently becomes
NaN coverage while a missing anchor list silently becomes an unriggable site.
createWorld now requires a site and says so.
