# Bayan (بيان) — Phase 6 Implementation Summary This document summarizes the changes and additions made during the implementation of **Phase 6: Cloud Persistence**. ## Overview Phase 6 introduced database-backed features using Supabase for authenticated users, while strictly preserving the existing editor architecture and maintaining offline/guest functionality. --- ## 1. Documents Persistence (Phase 6.1) **Goal:** Allow users to save, load, and manage their documents in the cloud. ### Files Created: * `src/js/documents-cloud/documents-api.js` (Supabase CRUD operations) * `src/js/documents-cloud/documents-state.js` (In-memory state manager) * `src/js/documents-cloud/documents-ui.js` (DOM interaction and auto-save logic) ### UI Additions (`src/index.html` & `src/css/components.css`): * **Sidebar Drawer (`#docs-sidebar`):** A collapsible right-side drawer named "مستنداتي" (My Documents) to list saved documents. * **Toolbar Additions:** * A button to toggle the sidebar. * A document title indicator (`#doc-current-title`). * A manual save button (`#doc-save-btn`) that pulses yellow when there are unsaved changes. ### Key Behaviors: * **Auto-save:** Automatically triggers every 60 seconds if the document has unsaved changes. * **Guest Fallback:** If a guest user opens the sidebar, they see a prompt to sign in with Google instead of an empty list or errors. --- ## 2. Saved Summaries (Phase 6.2) **Goal:** Allow users to save their generated summaries and view a history of past summaries. ### Files Created: * `src/js/summaries/summaries-api.js` (Supabase CRUD for summaries) * `src/js/summaries/summaries-ui.js` (History panel UI and save logic) ### UI Additions: * **Save Button (`#save-summary-btn`):** Added to the summary card next to the "Copy" button. * **History Panel (`#summary-history-panel`):** An accordion-style section added to the bottom of the "التلخيص" (Summarize) tab to view past summaries, preview them, and delete them. --- ## 3. Settings Sync (Phase 6.3) **Goal:** Synchronize user preferences (specifically the UI Theme) across devices. ### Files Created: * `src/js/settings-sync/settings-api.js` (Supabase Upsert/Read for user settings) * `src/js/settings-sync/settings-sync.js` (Synchronization orchestrator) ### Changes to Existing Code (`src/js/theme.js`): * Modified the `setTheme()` function to dispatch a custom `bayan:themechange` event. ### Key Behaviors: * **Debounced Saves:** When the theme is changed, it waits 1.5 seconds before syncing to Supabase to prevent spamming the database if the user clicks rapidly. * **Auto-Load:** Upon login, the app fetches the user's saved theme from the database and automatically applies it, overriding the local device default. --- ## HTML Integration (`src/index.html`) All the new modules were wired into the main application: 1. Script tags were added to the `` section. 2. The `DOMContentLoaded` event was updated to initialize the new cloud modules (`initSettingsSync()`, `initDocumentsCloud()`, `initSummaries()`). 3. The DOM structure was updated surgically via PowerShell scripts to insert the new UI elements cleanly without disrupting the existing flexbox layouts. ## Architectural Constraints Maintained * `src/js/renderer.js` and `src/js/selection.js` remain completely **untouched**. * The core editor loop (User Types → `getEditorText()` → `/api/analyze` → `render()` → `setEditorHTML()` → `restoreSelection()`) was not modified. * Cloud persistence APIs only interact with the editor via the safe, established boundary methods (`getEditorText()` and `loadDocumentText()`).
