"""
TWO TRUTHS & A LIE — An Interrogation in Twenty Questions.
Gumleaf Precinct koala noir on ZeroGPU. The player files three claims (two true,
one lie) and is interrogated by a koala detective — Det. Pip Barrow (Ternary-8B,
fast, jumpy) or Insp. Marlowe Grey (Ternary-27B, slow to wake, sharper). A hidden
second model instance ("Sgt. Wattle", the observation room) quietly profiles the
suspect's answers each turn and slips notes to the detective. The analysis is
NEVER shown during play; it appears only in the post-game case file.
Radical transparency: a persistent 🔴 REC banner + consent gate — every completed
interrogation is recorded as AI training data (local JSONL + private HF dataset).
Engine notes:
- Per-turn @spaces.GPU generator: start llama-server (PrismML fork, ./bin),
run analyst (Wattle) then detective (both on the same loaded server), yielding
"tick" markers throughout so the CPU side can perform loading-as-theater.
- The lie label NEVER enters any model prompt (see _detective_prompt/_analyst_prompt:
they receive claims + transcript only). The reveal is computed app-side.
- MOCK_LLM=1 runs a scripted fake GPU turn for local development/testing.
