## Key Patterns
- **Data persistence**: `this.saveData(this.data)` / `this.loadData()` — single object `{ settings, threads }`. Settings merge on load preserves new fields via per-entry spread for `promptButtons`.
- **Streaming**: `ClaudeClient.streamChat()` is an async generator; `ChatView` iterates it and calls `updateLastMessage()` per chunk. (Note: `requestUrl` delivers the full response at once — no true streaming.)
- **Context flow**: Query → `VaultSearch.search()` → context preview → user confirms → `sendMessage()` injects note content into the Claude prompt. Auto-retrieve skipped when prompt extension buttons are active.
- **Context flow**: Query → `VaultSearch.search()` or `EmbedSearch.search()` → context preview → user confirms → `sendMessage()` injects note content into the Claude prompt. Auto-retrieve skipped when prompt extension buttons are active.
- **Active search engine**: `plugin.activeSearch` returns `EmbedSearch` when enabled, else `VaultSearch`.
- **System prompt layering**: base system prompt → optional `systemContextFile` → active `promptButtons` extension files (each appended with `\n\n---\n`).
- **@mention syntax**: `@Notizname` — autocomplete triggers after 2 chars, inserts full basename. Parsing in `handleSend` matches vault filenames directly (handles spaces & special chars).
- **Prompt buttons**: `activeExtensions: Set<string>` tracks active button file paths. Mode hint panel shows `helpText` above input; hidden after send. Date-search buttons parse month from query and filter files by `getFileDate()`.

- **Event listeners**: Use `this.registerDomEvent()` for permanent listeners (auto-cleanup on view close). Inline `onclick` / `addEventListener` acceptable for dynamic elements that are re-created.
- **TypeScript**: `strictNullChecks` on, `moduleResolution: bundler`. No tests currently.
## EmbedSearch
- Model: `TaylorAI/bge-micro-v2` (default) — 384-dim, quantized ONNX, WASM backend via CDN (`cdn.jsdelivr.net/npm/onnxruntime-web@1.14.0/dist/`)
- Cache: `<vault>/.memex-chat/embeddings/<note-path>.ajson` — `{ mtime, vec }`. Manifest at `.manifest.json`.
- Models stored in `<vault>/.memex-chat/models/` (env.cacheDir).
- Incremental flush every 100 embeds; final prune of stale files on completion.
- Per-embed timeout: 13 s (120 s for first call while WASM/model loads).
- `reembedFile(TFile)`: debounced 2 s re-embed on vault `modify` events.
- `searchSimilarToFile(file, topK=10)`: cosine similarity with property/tag boosting (see below).
- `excludeFolders: string[]` — vault folder prefixes skipped during indexing.
- `contextProperties: string[]` — frontmatter keys whose wikilink values get +0.15 score boost; shared tags get +0.05 each (max 3). Scores capped at 1.0.
- Obsidian Sync wait: `waitForSyncIdle()` monitors vault events (5 s probe, 15 s quiet) before starting `buildIndex`.
- esbuild patches required: `stubNativeModules`, `forceOnnxWeb`, `forceOrtWebBrowserMode`. `import.meta.url` defined as a constant string.
## RelatedNotesView
- Opens in right sidebar leaf via `plugin.activateRelatedView()` or sparkles ribbon icon.
- Refreshes on `active-leaf-change` and `file-open` (400 ms debounce).
- `onIndexReady()` called by plugin after `buildIndex` completes.
- Shows: note title, folder path (dimmed), similarity bar + percentage.
- "verknüpft" badge (accent colour) for notes boosted by a property link.
