Separate API and Client Extensions +**Decision:** Extensions have separate .Api.dll and .Client.dll assemblies + +**Why:** +- Enables distributed deployment (different servers) +- Clear separation of concerns +- Client can be static files (CDN, S3, user's PC) +- API can be centralized (database access, compute) + +**Benefits:** +- User downloads 5MB client instead of 500MB with DB/models +- You can scale API independently +- Users can customize client without touching API +- Reduced attack surface (client has no DB credentials) + +### 2. HTTP Communication via ExtensionApiClient +**Decision:** Client extensions call API via type-safe HTTP client + +**Why:** +- Works across network (different servers) +- Standard REST APIs +- Easy to debug (browser dev tools) +- Can add authentication/authorization later + +**Benefits:** +- No tight coupling between Client and API +- Easy to add caching, retries, circuit breakers +- Works with load balancers, reverse proxies +- Can monitor traffic with standard tools + +### 3. Manifest-Based Discovery +**Decision:** Extensions declare capabilities in extension.manifest.json + +**Why:** +- Load extensions without executing code first (security) +- Validate dependencies before loading +- Generate documentation automatically +- Enable/disable extensions without code changes + +**Benefits:** +- Clear contract between extension and system +- Easy to see what an extension does +- Can generate UI from manifest (admin panel) +- Version compatibility checks + +### 4. Dynamic Assembly Loading +**Decision:** Use AssemblyLoadContext for isolated loading + +**Why:** +- Hot reload support (unload/reload without restart) +- Isolated dependencies (extensions can use different library versions) +- Memory cleanup (unload unused extensions) +- Sandboxing potential (future security feature) + +**Benefits:** +- Dev experience (hot reload) +- Stability (bad extension can't crash entire app) +- Resource management (unload unused extensions) +- Future-proof (can add sandboxing later) + +### 5. Dependency Resolution +**Decision:** Extensions can depend on other extensions + +**Why:** +- Editor extension needs CoreViewer (to show datasets) +- AITools needs Creator (to import AI-generated data) +- Avoid code duplication + +**Benefits:** +- Smaller extensions (reuse functionality) +- Clear dependency tree +- Load in correct order +- Fail fast if dependency missing + +--- + +## 📝 TODO Scaffolds Summary + +All files have extensive TODO comments explaining: +- **What needs to be built** - Specific implementation tasks +- **What calls it** - Which components depend on this code +- **What it calls** - Which dependencies this code uses +- **Why it exists** - The purpose and design rationale + +### Phase 3.1: Implementation (Next Up!) + +**Location:** All `src/Extensions/` files + +**Tasks:** +1.
