The last unbuilt Tier 1 item. A passage was a bore through rock with no
floor inside the walkable angle, so its mouth was not a standing position
and neither was anything near it -- the departure mouth measured a FOUR-CELL
player-fit component. You arrived and there was nowhere to stand.
Both ends of all 7 passages now open into a landing, sized from the body:
capsule diameter 2.72 vox floor >= 12 vox (3 m) to stand and turn
capsule height 7.04 vox room >= 12 vox tall, stock mouth gives 18 (4.5 m)
3-voxel floor slab, tube tangent to it -- no lip to climb out of
connector 5-vox radius: 2.5 m clear width, 3 m clear height
ramps over 44 deg get a deterministic level dog-leg
⭐ THE MOUTHS ARE NO LONGER SPECKS:
archetype components largest arrival-departure
Maze 309 -> 340 176 -> 3210 43-81 -> 3210-3210
TunnelNetwork 467 -> 227 1292 -> 3841 2-1 -> 3841-269
Underwater 86 -> 117 35 -> 3838 3-11 -> 3838-267
FlatPlain 45 -> 11 259 -> 2130 1-1 -> 268-273
CrystalChamber 197 -> 90 24 -> 286 1-1 -> 286-274
FloatingIslands 2 -> 1 3 -> 72 1-1 -> 72-72
Law 1/8 -> 2/7 connected (1 refused on MaxCells), and critically ZERO
connections now run through a four-cell pocket.
Every landing floor was verified against the FINAL density, after all posts:
14/14 pass the 44 deg slope bracket, worst room gradient .059, worst
connector .522. 14/14 deterministic root joins. 0 seal failures.
0 box-verdict violations across 82 proved + 174 mixed, 109,142 voxels.
Op-stack bit-identical, order-independence green over 10 slots / 31
passages / 3 pool orders. Cache 0.665 us rebuild, 0.646 us hot.
Post order: origin spine -> vertical seal -> passage tube + landing floor
-> XY edge seal. Landings clamp 4 voxels inside the vertical seal; the XY
seal stays last and wins at world edges.
⚠️ ARCHITECTURAL NOTE, not a detail: landings join a deterministic annular
ROOT HUB at (0,0), built identically for every endpoint -- no nearest-
component search, no passage ordering. That is what makes the join
guaranteed rather than likely, and it extends the (0,0) spine concept from
a landmark into a structural network. It also means routes tend to pass
through the centre, which is a gameplay consequence worth Jahni's eye.
⚠️ AND IT DOES NOT CLOSE THE LAW. Codex is explicit: the landings guarantee
membership in the new root network, NOT in the archetype's pre-existing fit
component. The whole-strate Maze check still shows a 71.9-voxel gap between
1,235 and 2,938-cell components. So the native corridor networks remain
disconnected from the root network in places. Real, separate, next.
52 build-and-measure cycles, ~9 hours, finding real geometry bugs on the
way (a landing floor overlapping the ramp cells and hiding a floor
discontinuity; the disturbance pass refilling connector headroom).
Build clean, 32/32 success, 0 failed. Showcase regenerated.
