FRICTION, NEVER A BLOCK · THE GUARD FOLLOWS THE PERSON, NOT THE PRODUCT
Dart removes reflection through stimulation. Meridian removes reflection through efficiency. Tenet restores one deliberate moment in both. Here: the same cooldown that guards 0DTE options on a phone, holding a revenge-sized short sale in a professional equities workstation.
01 · WITH TENET — 9:53, THREE LOSING ROUND TRIPS, FLAT, A 1,000-SHARE SHORT TYPED · INTERACTIVE
» Transmit with the button or ⇧⏎ — the loss cooldown steps in at send with three ways forward: start the 9-minute cooldown, override with a reason, or cancel. After the wait you confirm at a refreshed bid, or edit, or cancel. Nothing sends by itself. Demo time runs ~36× faster.

POSITIONS
FLAT — no open positions
Day P&L−$360.00
▸ Meridian does not gamify trading. Its risk is speed: after three losses, a revenge-sized short remains one keystroke away.
▸ THE ONLY COLORED OBJECT — the broker is deliberately near-neutral, so the card carries all the register change. When the guard speaks, the room changes; nothing else moves.
▸ CONTAINMENT — two contained changes: a quiet status indicator and an active intervention at transmit. Diff the frames and chart, depth, order context, and positions are identical.
▸ The market keeps printing while the countdown runs — waiting happens in front of a moving chart. The guard holds the door, never the room.
