Edge work begins with the named hardware, software image, sensors, competing workloads, environmental assumptions, and communications profile. Measuring that complete target establishes where latency, memory, power, temperature, timing, or accelerator support constrain the workload, and prevents a workstation result from being treated as field evidence.
The operating envelope also assigns authority. Perception, recommendation, control, and emergency behavior are separated, then examined under stale sensors, uncertain output, resource pressure, and lost connectivity. This makes local continuation, queuing, operator escalation, and safe-state transitions explicit before optimization decisions narrow the available options.
