selectedAiProvider function

Implementation

  final remote = ref.watch(userAiSettingsDatasourceProvider);
  // Local storage holds the last-known selection — fast and works offline.
  // We treat it as the source for which provider is "active" because the
  // remote table holds settings keyed BY provider, not the active provider.
  final value = await storage.read(key: AiProviderConfig.providerStorageKey);

  // Defensive fallback when the local-LLM feature is gated off but the user
  // still has 'local' persisted (e.g. cleanup hasn't run yet, or a remote
  // sync row replays the value). Treat as Claude so the downstream
  // datasource never resolves to a disabled provider.

  }
  // Best-effort: if there's a Supabase row for this provider, mirror its
  // credential into local storage so any subsequent reader (e.g. the
  // ai-proxy headers builder) sees the synced value without an extra
  // round-trip. Failures are silently ignored — local cache stays canonical.
