test(measure): the window was NOT the problem -- my sixth hypothesis dies

I thought the fitted mouth-AABB window was cropping an origin-routed path
and producing a false NotConnected. Codex tested it three ways at step 1 on
the Maze candidate Jahni walked:

  mouth-AABB + margin      842,996 cells    NotConnected
  origin-inclusive       3,251,556 cells    NotConnected
  WHOLE STRATE          31,881,528 cells    NotConnected

115,578 fit cells, 2,903 components, largest 11,418 -- and the mouths sit
in components of 172 and FOUR cells, 274 voxels apart. The window was never
the problem. Sixth measurement hypothesis, first one that was wrong in the
other direction: this time the instrument was fine and I doubted it.

The window rule still improved: bIncludeOriginInCoverWindow now covers the
route an origin-rooted topology actually implies (Maze, VerticalShafts,
TunnelNetwork, Underwater), expansion happens BEFORE MaxCells, and an
over-cap window is REFUSED honestly instead of silently cropping back to a
mouth-only box. VerticalShafts refused at the 4M production cap and said so.

Corrected law across eight: 0/7 measured Connected, 1 unknown
(CoarseLiedBudgetExhausted), 1 refused.

⇒ FIVE CAUSES NOW ELIMINATED: size (Jahni walked it), the fit stencil
(fixed, 309 pockets -> 96), placement (mouths land on legal poses),
corridor connectivity (spanning tree, 0 disconnected cells over 64 seeds),
and the measurement window (whole-strate says the same thing).

⭐ AND THE REMAINING CAUSE IS NAMED BY ITS OWN NUMBER: the departure mouth
sits in a FOUR-CELL player-fit component. A passage tube is a bore through
rock -- sloped or vertical, no floor within the walkable angle -- so the
mouth point is not a standing position and nothing around it is either.
You arrive and there is nowhere to stand.

That is precisely COMPOSER-NOTES §6.5 / Tier 1's unbuilt item: "the passage
mouth becomes a room plus a distinctive landmark". It was never started.
The law cannot pass while a mouth opens into a bore instead of a landing.

Build clean, 32/32 successful, 0 failed, same two known warnings.
WorldRadiusVoxels=0, lateral gating, determinism, equivalence all intact.
