Hedges stay in their squares; the eyes turn to the lock they pick

Eric's rosebush-through-a-wall, hunted to two roots. A camera-facing
billboard viewed obliquely rotates out of its square, so cell-bound
volumes are now windowed to the exact segment where their plane
crosses their own cell — no end may paint beyond it. And the real
smoking gun: the near-bias that lets a hedge win the tie against the
wizard standing in it was applied to the OCCLUSION depth too, letting
the hedge cheat a fifth of a cell through any neighboring wall. The
bias now orders sprites among themselves only; walls always judge the
true depth.

Also answered: edge-deeds turn the head. Picking or jamming a lock,
unlocking with the Master Key, raising or razing or drowning a wall —
any edge-bearing deed by the reel's own wizard now aims the camera at
that edge's midpoint before the outcome shows, same as any other
target.
