Concretely: * Fetch URL: /workspaces/:id/compute-options → /compute/metadata. * useEffect dep: [workspaceId] → [] (workspace-independent endpoint, one fetch per tab mount is enough). * ComputeOptions gains a 'labels: Record' field so the cloud-provider selector can render human labels from the SSOT too (was a hardcoded CLOUD_PROVIDER_LABELS constant before). * The fetch handler maps the per-provider object shape into the internal flat ComputeOptions shape with defensive fallbacks: if the response is missing label/default_instance/instances, we keep the in-bundle value for that field rather than dropping it. If the response is malformed (no providers, or all entries fail the id check), we keep the full FALLBACK_COMPUTE_OPTIONS. * Cloud-provider option label now derives from computeOptions.labels (with the value as fallback), so it follows the SSOT. Fallback path (FALLBACK_COMPUTE_OPTIONS) mirrors the server's current allowlist verbatim, so the UI never breaks if the fetch fails or returns empty. Tests updated: * The two SSOT-path tests now use the real response shape ({providers: [{id,label,default_instance,instances}]}) and assert the call is GET /compute/metadata (not the workspace-scoped URL). * All other tests inherit the default apiGet mock-reject in beforeEach, so they exercise the fallback path — their assertions (t3.medium / cpx31 / m6i.xlarge) remain satisfied by the offline default list.
