• aastroctl openapi import — generate a gateway configuration from an OpenAPI 3.x document. Documents produced by openapi export --extensions are reconstructed losslessly: flows, aggregation, upstreams, policy, and transport are restored, with default-valued fields elided for a minimal, human-readable result. Foreign documents are scaffolded as single-upstream flows, with hosts taken from --default-host or servers[]. Passthrough flows are detected from streamed / responses, and the rate limiter is inferred from 429 responses. Secrets are never restored: plugin/middleware configs and TLS certificate paths are reported as warnings for manual re-adding. The generated config is validated before output, so import never emits a config the gateway would reject.
