Three laws, one constitution: record every touch, tell the truth about every state, and under stress shed speed, never legality. They interlock; adopt all three or the gap leaks through the one you dropped.
Enforcement lives at the endpoint, never in the UI or in policy; a grant not checked at the point of service is a wish. The ledger is symmetric: platform and insider reads land beside external ones.
No false errors, no optimistic countdowns, no dead ends dressed as waiting screens. Every blocked state names its reason and next action.
The degraded mode is the slower lawful path, never the faster unlawful one. The epistemic governor compiled into architecture: permission contracts as conditions degrade.
Law 3 is only safe because Law 2 tells the truth about the slower path; Law 2 is only auditable because Law 1 recorded what happened. Keep two and the gap leaks through the one you dropped.
One breath: record every touch, tell the truth about every state, and when things break, get slower, never get illegal.
