For the after-work collapse — the evening that's gone before it started. You walk in the door at six with a plan. By half-eight you're on the couch and you don't remember deciding to be there. It isn't laziness — you ran a full day at work. It's the transition that breaks. Work gives your brain structure all day; then you cross your own doorway and the scaffolding vanishes, and the home-brain doesn't come online fast enough. The Threshold is a three-move protocol for the first minute home — run before you sit down, before the couch decides for you. No app, no streak, no system to keep up. A card by the door and ninety seconds of motion. What's inside: The three moves — land your things, the reset action, the first task A ten-minute setup you do once and never again Edge cases: exhausted, home late, someone else home, forgot for a week How to keep it working when the novelty wears off Instant PDF. Read it on your phone, print the card, keep it by the door. Part of the Protocol Collection — tools for demanding brains. Not clinical advice; for persistent difficulties, speak to someone who can help.
