Tester-reported fixes (bugs 2–4 of the batch; bug 1 shipped in v0.5.4):
/model <invalid>no longer persists a broken model. Unknown ids are validated against the live catalog and rejected with top-3 fuzzy "did you mean" suggestions. Previously a typo was silently saved to config and broke every future launch — with the error only surfacing on your next prompt. Offline still sets, with an explicit warning./fallback <invalid>is rejected when the catalog is reachable (was warn-but-keep — a bogus fallback list breaks failover exactly when you need it). Offline keeps with a warning.--route previewis now accepted at launch for parity with the in-session/route preview(it explains a preview needs a conversation first).
Upgrade: pipx upgrade meshapi-code — or press y when the CLI offers it.
