Where Regen Engine Belongs
Regen Engine is not optional. It becomes necessary wherever incorrect execution produces irreversible consequences. The Core Requirement Any system where incorrect execution produces irreversible consequences needs structural execution control — not better error handling, not smarter monitoring, not more robust retry logic. Control must exist at the geometry level — or it does not exist at all. Concrete Domains Autonomous Vehicles Declared geometry: velocity ≤ 130 km/h , obstacle_distance > 3m , trajectory ∈ valid_path . Any input violating these constraints — whether from a corrupted sensor, a software bug, or an external attack — does not execute. There is no exception handler that "saves" the situation. The transition does not exist. [REGEN] REJECTED (geometry) → velocity 999.0 exceeds declared limit 10.0 This is not a log entry. This is the system working correctly. There is no recovery from invalid execution at 130 km/h. Agentic AI Systems Wh...
