Integration preflight

The legacy name for the client-orchestrated preflight workflow.

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

Client 0.5.1 adds opt.preflight(measure, x0, budget=6). The client applies the exact inversion-of-control handshake documented at /docs/preflight; the hosted endpoint never attempts to invoke your local instrument function.

Preflight setup acquisitions are counted separately from controller cold start. A boundary result is not failure, but it is not fit. A decline must be corrected before starting the maintained session.

opt = SWCOptimizer(key, n=len(target), target=target, tolerance=0.05)
report = opt.preflight(measure, x0, budget=6)
x = opt.start(x0)
for _ in range(rounds):
    x = opt.step(measure(x))
proof = opt.end()
