#% MAX_SCORE: 100
# The Lurking Horror (Infocom Release 221, serial 870918, Z-machine V3)
# VERIFIED COMPLETE SOLVE: 100/100, won=True, died=False
#
# Reproduce with the RNG-pinned replay harness (free, no API):
#   cd ~/src/zwalker
#   python3 scripts/replay_solve.py games/zcode/lurking.z3 walkthroughs/lurking_verified_100.txt --seeds 24 --out solutions/lurking_verified.json
#   => lurking_verified_100.txt: VERIFIED 100/100 at seed 1 | 306 cmds | died=False | won=True
#
# Ending: the high-voltage line is plugged into the lair box, the whitish
# mass compacts into the winged frob, and the red-hot smooth stone thrown
# down its throat makes it swallow itself; picking the cracked stone up
# frees something small and winged, and the hacker crawls out of the mud:
# "Can I have my key back?" — "Your score is 100 of a possible 100, in 310
# moves. Graded on the curve, you are in the class of President of the
# Institute."
#
# Why a pinned seed (no restart prelude needed — boot draws no randomness;
# two boots are byte-identical and the seed is pinned right after start()):
# the game has exactly two pieces of state-relevant randomness. (1) The
# urchin wanders a random open exit every 10 turns and ROBS every takeable
# object out of any player-less room he enters (I-URCHIN, frob.zil:346-436)
# — the route stashes tools twice (Tomb-crack size limit, elevator-shaft
# trip) and needs to MEET him once, animated hand out, to scare the bolt
# cutter loose; (2) entering the elevator pit or Steam Tunnel East presses
# a random elevator call button 25% of the time (RANDOM-ELEVATOR-MOTION,
# cs.zil:3460-3464), which can park the car away from floor 1 where the
# chain-to-hook gag needs it. Under seed 1 the urchin walks into the
# Infinite Corridor west end right on schedule, never robs a stash, and
# the car stays put. Everything else is turn-based clockwork (waxer
# 5-turn ping-pong, rat approach, professor TIED-UP? count, microwave,
# freeze/exhaustion timers, frob END-CNT window) and replays identically
# under any seed with the same command list. Mechanics verified against
# the official ZIL source (github.com/historicalsource/lurkinghorror);
# route machine-validated at 100/100 on seeds 1,3,4,5 verbatim and on
# 2,7 with the recorded adaptive recoveries (6/8 sweep) during research.
