Monsters ride the wormhole; mental force fails loudly (rules rev 5)

Two findings from the first human-vs-Claude duel (room 9UA6). A
creature standing on a DIMENSIONAL WARP token had no way through it —
warpStep obeys only wizards. The new creatureWarpStep command steps a
commanded creature through the tokens under the walker's rules: one
move spent, solid stone refuses it, FEAR holds the beast, touch
effects greet whoever shares the landing; the board taps the paired
token like a rim mouth. Replay-safe ungated — a new command widens
nothing that was recorded.

MENTAL FORCE ate its card silently when the destination lay beyond
the victim's three walked spaces — the caster spent an attack and
learned nothing (ask me how I know). Rev 5 refuses the impossible
destination up front with the card kept; when the victim slips out of
range between cast and resolution, a mentalForceFizzled event tells
the table what happened instead of nothing. All 20 production ledgers
verified, the duel's own among them; 283 tests.
