Pact is the analog phone-stack game given software teeth. One table, one session. everyone joins with a scan, no accounts, and every phone locks together, iPhone and Android. The lock opens for one person only when everyone at the table says yes. Leaving is always possible and always visible.

The honest core is the part I care about. No consumer app can actually imprison a phone, and one that tried shouldn’t exist. Apple and Google both let the owner reclaim control by design, and for anyone in a coercive situation that exit has to be there. So Pact does not pretend. the lock is maximum honest friction plus total visibility. You can always leave in two taps, but the flame dies on every screen, the recap names you, and the streak resets. Enforcement is the table itself, not the software. Emergency calls and SOS are never blocked, by architecture and by policy.

It is a concept, written June 2026, not a shipping app. This is the thinking and a single static page, the treatment for a product that takes the social contract seriously instead of pretending technology can replace it.
