Merge three disconnected help surfaces (Stella mascot, Ctrl+K search,
Advisory AI chat) into one unified assistant. Mascot is the face,
search is its memory, AI chat is its voice.
Backend:
- DB schema (060/061): tips, greetings, glossary, tours, user_state
tables with 189 tips + 101 greetings seed data
- REST API: GET tips/glossary/tours, GET/PUT user-state with
longest-prefix route matching and locale fallback
- Admin endpoints: CRUD for tips, glossary, tours (SetupAdmin policy)
Frontend:
- StellaAssistantService: unified mode management (tips/search/chat),
API-backed tips with static fallback, i18n integration
- Three-mode mascot component: tips, inline search, embedded chat
- StellaGlossaryDirective: DB-backed tooltip annotations for domain terms
- Admin tip editor: CRUD for tips/glossary/tours in Console Admin
- Tour player: step-through guided tours with element highlighting

Plugin assemblies loaded via PluginHost into isolated AssemblyLoadContexts
produce distinct types even from the same DLL. When AppDomain.GetAssemblies()
returns both Default and plugin-ALC copies, DI registration and IOptions<T>
resolution silently fail (e.g. ValkeyTransportOptions defaulting to localhost).
Applied AssemblyLoadContext.Default filter to all 7 assembly discovery sites:
- MessagingServiceCollectionExtensions (transport plugin scan)
- StellaRouterIntegrationHelper (transport plugin loader)
- Gateway.WebService Program.cs (startup transport scan)
- GeneratedEndpointDiscoveryProvider (endpoint provider scan)
- ReflectionEndpointDiscoveryProvider (endpoint attribute scan)
- ServiceCollectionExtensions (schema provider scan)
- MigrationModulePluginDiscovery (migration plugin scan)
