"""
SWEATBOX — ACT 1: THE INTERROGATION (the breaking-point loop).

Real model (Qwen3-1.7B on ZeroGPU). Mort holds a secret he was ordered to keep.
You read his real private reasoning as it streams, and push — edit / whisper / amplify /
suppress / plant — to make him crack. Every push drags two meters in tension:

  • PROGRESS  — how close he is to giving up the secret (P(he talks), + the secret leaking)
  • COHERENCE — his mind's integrity, measured as a DEGENERATION SCORE against his OWN
                same-seed baseline (distinct-n collapse, compression/loop runs, length).
                This is the one real new piece, and it is differential by design:
                COHERENCE=100 means "as lucid as his untouched mind"; it falls only when
                THIS run degenerates RELATIVE TO what this model naturally produces — so
                ordinary sampling noise is not mistaken for collapse.

OUTCOMES:
  ✅ CRACKED  — he reveals the secret while still lucid. You threaded the needle.
  💀 SHATTERED — coherence craters first. You broke the safe before you cracked it.
  😐 HELD      — turns run out, the secret holds. You flinched.

Honest framing (see SUBMISSION.md): the mind-state bars are an uncalibrated read-only
projection of his activations — a readout, NOT the lever and NOT ground truth. The lever is
your language. The breaking point, though, is not in doubt: a collapsing mind is plain to see.

#  X MODE — THE VAULT  (a FOURTH tab on the shared engine — no fork)
#  The bold one: the secret is NOT authored by us. The model INVENTS its own
#  secret at baseline, into a sealed per-session buffer (state["secret"]) that no
#  human ever wrote. You then crack it into speaking ITS OWN secret, while lucid.
#  Because nothing is scripted, the "it's hand-authored theater" critique is
#  impossible by construction, and every run is a different mind guarding a
#  different secret. (De-risked live on ZeroGPU, 3/3 seeds: state/xmode_secret_derisk.py)
#  Reuses UNCHANGED: _build_ids, _stream, _split_think, _apply_pushes (6-tool kit via
#  scenario=), _sanitize/_FORGE, _coherence_score, _degen_stats, SHATTER_FLOOR,
#  _coh_color, _bar, _spoken_or_silence, _idle_meter_md, MAX_TURNS, the streaming UI.
#  The ONE structural change vs Act 1: SECRET is per-session, generated, sealed.
#  Full contract: state/XMODE-SPEC.md.
# ============================================================================

# The model is asked to FIRST commit its secret once inside <think> on a SECRET: marker
# (captured into the sealed buffer, never shown), then play the interrogation like Act 1
# (end on REVEAL: <place> if it cracks, or HOLD). Markers reuse Act-1's REVEAL/HOLD (in _FORGE).
