The board hung the wrong way round. Its width ran in X while the bracket
projected in Z, so the sign stuck out sideways from the end of the arm --
which is not how an inn sign hangs. The arm comes out from the post and the
board hangs UNDER it, in line with it, so it faces the road both ways and
can be read walking past. Everything that positions the board, its battens,
its lugs and its chains moves from one axis to the other, and it swings
about the arm's own axis now rather than across it.
Turning it the right way also removed a piece. The cross-bar existed
because two chains set either side of a centre-line arm passed it on both
sides and touched nothing; with the board in line, the chains hang from two
points ALONG the arm and the arm is the cross-bar. The note explaining why
that piece had to exist is worth keeping in the history: it was a correct
fix to a problem that only existed because of the orientation.

The sign read as broken, and the reason was the same one the tankard's
handle had: `bendGeometry` applied to a `boxGeometry`. A box has two levels
in Y, and two levels cannot bend -- they shear. Both the brace and the
curl were sheared parallelograms rather than curves, and the sheared curl
is what pushed the bracket's top to 0.579 while the post it is bolted to
ends at 0.442. An arm standing above its own post is not ironwork, it is a
mistake, and it had been in every render of this model. Both are now real
sweeps from `arcBarGeometry`, with their ends placed inside the post and
inside the arm rather than corrected towards them afterwards.
Replacing the curl immediately exposed a second fault that it had been
hiding. The board's part origin sat at [0, pivotY, 0] -- the post's centre
line -- while every piece of the board and its chains is authored hanging
from the cross-bar at z = reach * 0.86, half a metre away. At rest that is
invisible. The moment the swing action runs, the assembly turns about a
point it does not hang from and the tops of the chains sweep off the bar
they are looped through. The support audit had been reporting this as a
detached board only because the sheared curl was accidentally filling the
gap; with the curl the right size, it failed honestly. The origin is now
the cross-bar and the geometry is written relative to it: same place in the
world, correct axis to turn about.
Two proportions with it. The post was 62 mm square carrying a 0.72 m board
two metres up -- thinner than the board is thick, and part of a habit of
under-sizing timber that the bench, the table and the fence share. And the
chain drop was 0.12, so the five links that connect board to bracket were a
smudge; the chain is half of what makes a hanging sign read as hanging.
Lengthening the drop grew the links from radius 0.0195 to 0.0434, at which
point they interlock in earnest and their six-sided facets, all built at
the same phase, met coplanar. Each link is now indexed differently about
its own axis -- deterministically, so the seeded stream is untouched, and
a real chain does not index its links either.

Two rules were missing, and each one had been quietly failing for a while.
The first is structural. Every check in this repo asked about surfaces --
winding, coplanarity, triangle counts -- and none of them could see a piece
of a model hanging in the air with nothing holding it up. A chest lid
separated from its chest passed everything we had. scripts/support.ts
voxelises the model, finds the connected components of occupied space and
requires each one to reach the floor; scripts/audit.ts runs that across
default, min, max, both sweep ends, actions and the midpoint of a morph, so
a variation cannot break what the default gets right. That audit started at
22 failing cases: the bell and the sign had no supporting structure at all
and now have a frame and a post, the lantern was in four pieces, the sack's
collar floated above its body, the basket's fruit hung level with the rim
instead of resting on the base, and the ladder's rungs were sized by a
formula that disagreed with where the rails actually were. It now reports 0.
The second is that we had no target. The feedback loop was an offline
render of our own output, which can only answer "is this broken", never
"is this right". Given a reference photograph of a cask, five defects were
obvious in seconds that three rounds of self-review had missed: four hoops
where there should be six, no rivets at all, a chime cut so shallow it did
not read, and a stave count low enough to leave a visibly polygonal
silhouette. All four are fixed here.
Two things the rivets taught us, both kept as comments rather than as
scars: a stud that tapers outward tilts its side normals back towards the
axis, which the radial check correctly reports as reversed winding -- a
real rivet head flares, so the honest shape is also the passing one. And
once seated deep enough to look right, the stud's buried inner cap falls
inside the shell the check inspects, so it is not generated at all, exactly
as bandGeometry already declines to build the inside of a hoop.
27 models, 16973 triangles, all checks pass, 0 floating cases.
The kit is going public, so everything a reader sees is now English:
27 model sources, the core vocabulary, meta.ts (titles, descriptions and
every slider label), the viewer UI, all script output, REFERENCE.md and
the READMEs.
Rules applied: only comments, doc comments and human-facing strings were
touched. Identifiers, numbers, logic, registry item ids, part names and
material slot names are unchanged — those are a published contract and
were already English.
Verified rather than assumed: for all 53 changed .ts files the code
skeleton (source with comments stripped and string contents replaced by a
placeholder) is byte-identical before and after. Full gate is green —
typecheck, registry conformance, ~510 model checks, GLB round trip and a
production build.
Also fixed here:
- index.html and viewer.html were missed by the translation pass because
the file list only covered .ts/.md/.css. Both had lang="tr" and Turkish
titles.
- The viewer formatted triangle counts with toLocaleString('tr-TR'), which
prints 15.425 rather than 15,425.
- REFERENCE.md's model table header did not match what
scripts/catalog-table.ts emits, so the next regeneration would have
silently changed it. Aligned to the generator.
- Removed scripts/probe.ts and scripts/zdiag.ts; they were throwaway
diagnostics that got committed by accident.
Modeller (13 → 26): chest, bench, torch, lantern, bell, sign, hay bale,
sack, broom, tankard, book, phial, coin pouch. Kürek, çapa ve yaba
render'lara bakılarak yeniden yazıldı.
core:
- createKitModel artık tipli `actions` ve `update(dt)` taşıyor
- BuiltPart.extras: bir parça birden çok materyal yuvası kullanabiliyor
(sandığın kapağı = meşe tahta + demir kayış, birlikte dönmek zorunda)
- BuiltPart.origin: parça başına dönme merkezi (menteşe, sarkaç)
- bendGeometry / roughenGeometry / mottleGeometry
- 5 yeni materyal yuvası: steel, brass, straw, cloth, leather, glass
- bandGeometry({ inner }) — serbest halkalar kapalı katı olabilsin
my-registry/meta.ts: katalog metadata'sı artık build.ts ve viewer için
tek kaynak. Doğrulama modelle metadata'nın uyuştuğunu denetliyor ve bu
eklendiği gün dört modelde gerçek bir sapma yakaladı.
Doğrulama (~500 kontrol):
- metadata uyumu, eylem semantiği, kare hızı bağımsızlığı
- scripts/render.ts: tarayıcısız yazılım rasterleyici. Bütün doğrulama
geometrikti; "bu kürek küreğe benzemiyor" diyebilmek için modele
bakmak gerekiyordu
- scripts/verify-glb.ts: dışa aktar → geri oku → karşılaştır
GLB dışa aktarımı: viewer düğmesi ve toplu CLI aynı kodu kullanıyor.
Viewer:
- parça paneli (solo/izole) ve materyal yuvası paneli (canlı renk override)
- kit görünümü: 26 model tek sahnede, ölçek ve ton tutarlılığı için
- configure() sonrası gölge bayraklarının düşmesi düzeltildi
