Integration preflight

Validate the documented loop before a production run.

The shipped client exposes start(), step(), and end(). There is no separate calibrate() method.

Run a bounded preflight with the normal regulation loop: begin from a known safe configuration, use a measured reachable target, execute three to six updates, and confirm vector order, actuator bounds, same-cycle timing, and response quality.

Always call end(), including after a failed check. A preflight validates the integration; it does not rescue an unavailable component response, an infeasible target, or incompatible action timing.

opt = SWCOptimizer(key, n=len(x0), mode="regulation", target=target)
x = opt.start(x0)
for _ in range(rounds):
    x = opt.step(measure(x), target=target)
opt.end()
