The manual fetch_bambu_cert workflow works but needs two commands and a printers.toml edit. ensure_trusted() collapses that into one call, using the same trust model SSH uses for host keys: - a pin already on disk (certs/pinned/<id>.pem) is used directly, no new trust decision is made on every run - no pin yet + bundled CA verifies fine (current-gen printers): nothing to do - no pin yet + bundled CA fails (P1P, etc.): auto-pins via trust-on-first-connect, same as fetch_bambu_cert, but automatic - an *explicit* pin (you set ca_cert_path yourself) never gets silently auto-pinned over — a failure there is a real error examples/auto_connect_bambu.rs demonstrates the one-command flow. Verified all three states against local test servers, not just compiled: first run with no pin auto-pins and connects; second run against the same server is silent (no re-TOFU message) and just verifies against the pin; third run after swapping the server's certificate correctly FAILS instead of silently re-pinning — confirms the security property survives the smoother UX.
