Three rulings from the night games (rules rev 2)

Teleport wraps the maze's rim: its four counted squares now step
through warp mouths like any doorway, so a wizard can blink off one
side of the board and onto the other.

A wizard at a door's threshold may pull it open and peek — lock
removed, door unlocked this turn, or PICK LOCK / MASTER KEY in hand —
without stepping through. The door still hangs shut to everyone down
the hallway; only a HELD door is propped open for every eye. Gated
behind rules rev 2 (now sourced from the engine's CURRENT_RULES_REV)
so stored games replay with their doors dark; the client's sight
mirror learns the same peek.

Fear no longer nails a cornered wizard to the floor: a step closer to
the dread is allowed when it walks the shortest way out of it, so
escape can round a corner. Standing outside and stepping in is still
refused.

All 15 production ledgers verified before deploy; 269 engine tests.
