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.
