Rung 10, thirty brain minutes inside the Pewter museum's upper floor (map 0x35):
macro starts MENU 82, BACK 82, GO FRONTIER 8, the event log alternating
`MENU start/done, BACK start/done`. MENU pressed START, the start menu opened,
and that scene's pad is CLOSE / CONFIRM / BACK -- so BACK pressed B and closed it
again. Two buttons that undo each other with nothing else changing, which is
section 12.10's rule one scene wider than a battle, and section 12.2's trap by
definition: a precondition satisfied wherever the fly stands and a macro that
completes without moving.
Nothing in the macro vocabulary uses the start menu for anything, so MENU comes
off scene_set's overworld row entirely rather than being narrowed. It stays a
type, a population, a tag and a script, so the roles, the channel order and
--print-compatibility are untouched, and the fly's raw START still opens the
start menu in macros mode.
MENU was also what made an empty overworld pad impossible. That guarantee moves
to the way out: `ways` gains one last resort for a *room*, the one GO ROUTE has
had outdoors since 13.1, so a map that offers nothing else at all still offers
its door or its staircase -- ignoring the blocked window, because a target the
ledger is resting is still the only place to go. The museum's staircase is a
passage and not an exit, which is why the old tier 3 could not answer for it.
A map with no way out at all is now a genuinely empty pad. No map in Red is
that, it is asserted as the named residual, and game.padEmptyMs reports it.
