§40.1 — the R39 blind spot, closed with both arms fired. Before: check_transmission()
parsed pipeline/_normalized/<file> only and returned SILENTLY when absent — so a
depot-only transmissive GLB (the longbench/streetlight shape) or a stale glass copy in
web/assets/models/ (what ?localdepot=1 actually serves) shipped unseen. After: all four
surfaces scanned — _normalized/ always, web/assets/models/ always, the DEPOT copy via
ranged GET of the GLB JSON chunk whenever no local file exists (206-aware, slices the
tailnet's 200-full), plus a sweep of every non-manifest .glb in both dirs (ped rigs and
dance clips load by literal path). A depot fetch failure is a LOUD warn, never a skip.
Controls demonstrated, not asserted:
arm 1 (served path): glass box_crate planted in web/assets/models/ only →
R39 gate rc 0 (the blind spot, live) · R40 gate rc 1 · fixture removed → rc 0
arm 2 (depot path): both local copies held aside, local mock depot serving glass →
rc 1 (depot copy) · clean bytes → rc 0 · REAL tailnet depot, local absent →
rc 0 / 0 warnings (production fetch path proven)
Nothing was ever published to the real depot namespace; sha1 6c327d86 restored both
copies; final validator on the real tree rc 0, 0 errors, 0 warnings, 39 manifest GLBs
+ 40 swept.
§40.4 — the arcade is a PLACEMENT rule, not an asset. Measured: one 42.00 × 5m arcade
edge, posts at d/2+2.2-0.2 = ±0.50m from the centreline — two rows 1.00m apart, 34
colliderless posts, 0.60m open slot. The kit designed as one thing: the roof spans
(depth 2.5 = half-lane, slabs meet flush) and a spanned roof has no posts. Proved
without touching B's tree — rule applied in-flight by a rewriting no-store server,
shot from inside the lane: draws 124→124 (+0), tris unchanged. Rule handed to B with
file:line; B applied it this round.
