#
# The Witness is scoreless. It is a V3 "time" game (header flags1 bit 1):
# the status-line globals 17/18 hold the CLOCK - hours and minutes - and the
# game's own source labels them exactly that way ("SCORE INDICATES HOURS /
# MOVES = MINUTES", events.zil in the official ZIL). There is no separate
# score global and no SCORE verb ("You don't need to use the word 'score'
# to solve this mystery."); the ending is decided purely by evidence flags.
# Hence the WIN_TEXT directive below: it matches the one letter from Police
# Chief Klutz that only the game's best ending prints - the trial jury
# CONVICTING Monica Linder, followed by "You have reached a complete
# solution to the story" (the author's-summary epilogue, which no other
# ending reaches).
#
# Ending: the documented best one. You witness Freeman Linder shot dead at
# 9:01 p.m. while seated across his desk, prove the hidden-gun mechanism
# (push the butler's button after the shot - a click from the grandfather
# clock - and have Duffy's lab confirm the keyhole powder is gun powder),
# establish Monica's motive by asking her about her mother in the opening
# scene, then hide behind the office lounge after the coroner's men remove
# the body at 11:33 p.m. At 11:55 p.m. Monica sneaks in, opens the clock
# with her hidden key and pockets the murder gun - witnessed. Accused, she
# admits helping build the mechanism; when Duffy returns from the morgue
# (12:42 a.m.), arresting Monica alone convicts her, with the top
# "Congratulations on your fine detective work" variant (no Duffy hints
# were ever requested).
#
# Why a pinned seed: the timing of the household is lightly randomized -
# Duffy's lab report on the powder comes back 15+RANDOM(15) minutes after
# he takes it, Monica gets home from the pictures at 670-RANDOM(20) game
# minutes (10:50-11:09 p.m.), and character goal-movement adds RANDOM
# variance - so the exact minutes at which waits are interrupted (and thus
# how many "yes"/"z" answers this recording needs) depend on the RNG
# stream. Seed 1 reproduces the recorded timeline exactly. Mechanics
# verified against the official ZIL source
# (github.com/historicalsource/witness): the best ending requires
# mechanism proof (MONICA-ADMITTED-HELPING, plus PLAYER-PUSHED-BUTTON +
# POWDER-ANALYZED for good measure), MONICA-HAS-MOTIVE, and
# SEEN-MONICA-AT-CLOCK, then arresting Monica by herself.
