This dramatically reduces the initial JS parsing block on the V8 main thread. +2. `mathjs` (~9.00 MB unpacked) - Lazily loaded only when math or variable evaluations are required. Now fully code-split to avoid blocking initial application load. --- ## 🔋 Battery & Idle Efficiency -**Status: 🟢 Good (Optimized)** +**Status: 🟢 Excellent (Optimized)** -This critical area for a background desktop app has been fully resolved. +This critical area for a background desktop app is fully resolved. **Zero-Idle Reminders:** -* `useReminders.ts` has been refactored. The inefficient 10-second polling loop has been removed. * The app calculates the exact millisecond the *next* earliest reminder is due and sets a single, targeted `setTimeout`. This achieves true zero-CPU idle time while waiting for reminders. **Power Throttling:** * The app utilizes Electron's `powerMonitor` API. When the laptop suspends or runs on battery saver mode, PaperCache cleanly pauses its background timers via IPC (`power:suspend`). When it wakes, it recalculates (`power:resume`). **Reactive `/var` Engine:** -* The global reactive variable and math calculation system evaluates AST trees synchronously. Without a debounce layer, typing rapidly in a massive document with many variables could trigger heavy synchronous calculations, stalling the render thread. +* Variable scopes and AST mathematical evaluations are debounced (300ms) within `App.tsx` and CodeMirror decorations (`plugins.ts`). +* CodeMirror view decorations dynamically render synchronous outputs using a globally cached state of variable scopes. Updates trigger asynchronously, completely eliminating synchronous rendering stalls during rapid typing in massive markdown documents. --- ## 🧠 Memory -**Status: 🟢 Good** +**Status: 🟢 Excellent** **Listener Leaks & Architecture:** -* Zustand stores are correctly utilizing slice-subscriptions (`useAppStore(state => state.notes)`), preventing massive re-renders across the React tree. -* `contextIsolation: true` and `nodeIntegration: false` are perfectly configured in the `BrowserWindow` preferences. -* IPC Event listeners (`ipcMain.on`) are mapped cleanly without duplicating listeners across re-renders. +* Zustand stores correctly utilize slice-subscriptions (`useAppStore(state => state.notes)`), preventing massive re-renders across the React tree. +* `contextIsolation: true` and `nodeIntegration: false` are securely configured in the `BrowserWindow` preferences. +* IPC Event listeners (`ipcMain.on`) map cleanly without duplicating listeners across re-renders. **Object Retention:** -* The `/ctx` AI command slices and retains strings up to 50,000 characters. While handled well, rapid succession of AI context requests could temporarily spike memory before V8's Garbage Collector catches up. +* The `openai` SDK has been refactored into a singleton instance. The client reuses the underlying connection logic instead of re-instantiating heavy objects on every `/ai` request, minimizing V8 garbage collection churn during repeated AI invocations. * CodeMirror efficiently virtualizes DOM rendering, meaning large files don't leak DOM nodes. --- ## ⚙️ Static Configurations -**Status: 🟡 Warning** +**Status: 🟢 Excellent** **Linting:** -* `npm run lint` yields 30 warnings. Most are harmless (`@typescript-eslint/no-explicit-any`, `no-empty`). +* `npm run lint` yields 0 errors and only 13 minimal warnings (`no-empty`, `no-console`, and some remaining `any` types that are safe or intentional). The majority of the codebase is now strongly typed. **Electron-Builder:** -* `asar` packaging is implicitly enabled (default), which is excellent. -* `compression: "maximum"` is not defined in `package.json`.
