 **Request:** "can you create a log with a summary of each task i have asked you to perform with a timestamp"  
 **Actions:**
 - Created this comprehensive task log
-- Documented all changes, reasoning, and outcomes
+
-- **Result:** Complete audit trail of development session

+
+### 9. Fix Missing /wiki Prefix on Links
+**Time:** ~1:00 AM  
+**Request:** "/wiki is not prepended on some of the links"  
+**Actions:**
+- Identified issue in markdown link processing (`src/markdown/mod.rs:72-96`)
+- Fixed relative links missing `/wiki/` prefix in page content
+- Modified link processing logic to add `/wiki/` prefix to relative links that don't start with `http`, `/`, or `#`
+- Added test case to verify fix works correctly
+- **Result:** Relative markdown links like `[Page](page-name)` now correctly become `/wiki/page-name`
+
+---
+
+### 10. Add Toggleable Filetree Title
+**Time:** ~1:05 AM  
+**Request:** "make the filetree title 'Filetree' and make it clickable and toggle the showing the contents"  
+**Actions:**
+- Updated both folder and wiki page templates in `src/server/mod.rs`
+- Changed "Files in this folder" heading to clickable "📁 Filetree" with cursor pointer styling
+- Added JavaScript toggle functionality to show/hide file tree contents
+- Icon changes between 📁 (open) and 📂 (closed) states
+- Applied to both `render_folder_page()` and `render_wiki_page()` functions
+- **Result:** File tree now has a collapsible interface with visual feedback
+
+---
+
+### 11. Move Filetree Above Article Content
+**Time:** ~1:10 AM  
+**Request:** "move the filetree above the article"  
+**Actions:**
+- Updated folder page template in `src/server/mod.rs` to move filetree outside and above the `<article>` tag
+- Updated wiki page template to move filetree above article content
+- Restructured HTML layout: `<main>` now contains separate `<div>` for filetree followed by `<article>` 
+- Maintained all existing toggle functionality and styling
+- **Result:** Filetree now appears above the main article content on both page types
+
+---
+
+### 12. Style Header Navigation in One Row
+**Time:** ~1:15 AM  
+**Request:** "put Home, search and logout all in one row"  
+**Actions:**
+- Added CSS styling to both folder and wiki page templates in `src/server/mod.rs`
+- Implemented flexbox layout for navigation bar with `display: flex`
+- Used `justify-content: space-between` to spread elements across the full width
+- Added padding, borders, and proper spacing for visual organization
+- Escaped CSS braces properly for Rust format strings (using `{{` and `}}`)
+- Applied consistent styling to both `render_folder_page()` and `render_wiki_page()` functions
+- **Result:** Header now displays Home link, search input, and auth section in a clean horizontal row
+
+---
+
+### 13. Redesign Navigation as Right-Side Column
+**Time:** ~1:20 AM  
+**Request:** "changed my mind. put home, search and login in a column on the right, with a border around the box"  
+**Actions:**
+- Completely redesigned navigation layout from horizontal to vertical column
+- Changed nav from header bar to fixed-position box on the right side
+- Added border styling: 2px solid border, rounded corners, light background
+- Implemented box-shadow for depth and visual separation
+- Set navigation to `position: fixed` at top-right (20px from edges)
+- Adjusted main content with right margin to avoid nav overlap
+- Removed unnecessary div wrappers for cleaner HTML structure
+- Applied changes to both folder and wiki page templates
+- **Result:** Navigation now appears as an elegant bordered box in the top-right corner with vertical layout
+
+---
+
+### 14. Change Font to Serif & Default Filetree Closed
+**Time:** ~1:25 AM  
+**Request:** "change back to serif font and default filetree to be closed"  
+**Actions:**
+- Changed `font-family` from `Arial, sans-serif` to `serif` in both templates
+- Updated filetree to start in closed state by default:
+  - Changed initial icon from 📁 to 📂 (closed folder icon)
+  - Added `style="display: none;"` to filetree content div
+  - Modified JavaScript to not load filetree content immediately
+  - Updated toggle functionality to lazy-load content on first open
+- Applied lazy loading: filetree content now only loads when user first clicks to open it
+- Maintained all existing toggle functionality while improving performance
+- **Result:** Site now uses serif font and filetree starts collapsed, loading content only when needed
+
+---
+
+### 15. Remove Navigation Box Shadow & Background
+**Time:** ~1:30 AM  
+**Request:** "take out the drop shadow on the box, and the background color"  
+**Actions:**
+- Removed `box-shadow: 0 2px 5px rgba(0,0,0,0.1);` from navigation styling
+- Removed `background-color: #f9f9f9;` from navigation styling  
+- Applied changes to both folder and wiki page templates
+- Maintained all other styling: border, border-radius, positioning, and layout
+- **Result:** Navigation box now has a cleaner, more minimal appearance with just the border outline
+
+---
+
+### 16. Remove Sans-Serif Fonts & Rounded Corners
+**Time:** ~1:35 AM  
+**Request:** "remove all sans-serif, even from the search box. remove the rounded corners from tha page as well"  
+**Actions:**
+- Explicitly set `font-family: serif` for navigation links and search input
+- Removed `border-radius: 8px` from navigation box styling
+- Removed `border-radius: 4px` from search input styling
+- Ensured all UI elements consistently use serif fonts
+- Applied changes to both folder and wiki page templates
+- **Result:** Complete serif typography throughout the interface with sharp, angular styling
+
+---
+
+### 17. Open Filetree by Default on Folder Pages
+**Time:** ~1:40 AM  
+**Request:** "if the page is a folder, then we should open the filetree by default"  
+**Actions:**
+- Modified folder page template to show filetree open by default:
+  - Changed filetree icon from 📂 (closed) to 📁 (open)
+  - Removed `style="display: none;"` from filetree content div
+  - Updated JavaScript to load filetree content immediately on page load
+- Simplified toggle functionality for folder pages (removed lazy loading logic)
+- Wiki pages remain unchanged - still start with closed filetree
+- **Result:** Folder pages now display file tree immediately for better navigation, while wiki pages maintain minimalist closed state
+
+---
+
+### 18. Add Markdown Table Support
+**Time:** ~1:45 AM  
+**Request:** "create a new branch for this next feature: let's try and render markdown tables"  
+**Actions:**
+- Created new branch `markdown-tables` for the feature
+- Modified `src/markdown/mod.rs` to enable table support:
+  - Added `Options` import from pulldown-cmark
+  - Updated parser to use `Parser::new_ext()` with `Options::ENABLE_TABLES`
+  - Added comprehensive test case for table rendering verification
+- Verified compilation with `cargo check` - all changes compile successfully
+- Tables now support standard markdown table syntax with headers and data rows
+- **Result:** Markdown tables now render properly with full HTML table structure (`<table>`, `<thead>`, `<tbody>`, etc.)

+### 25. Implement Wiki Page Editing Functionality
+**Time:** August 15, 2025  
+**Request:** "Let's add an editing functionality. Make a new branch for this or a small batch of kittens will die!"  
+**Actions:**
+- Created new branch `feature/wiki-editing` for development
+- **1. Added Edit Button to UI (only visible when logged in):**
+  - Modified `render_wiki_page()` in `src/server/mod.rs` to include edit button in navigation
+  - Added JavaScript to show/hide edit button based on JWT authentication status
+  - Button redirects to `/edit/<path>` when clicked
+- **2. Created /edit Route Handler:**
+  - Added `/edit/*path` route to serve raw markdown content for editing
+  - Implemented `edit_page_handler()` with authentication and permission checking
+  - Returns raw markdown content from WikiService for editing
+- **3. Built Multi-line Text Editor Page:**
+  - Created `render_edit_page()` function with full HTML template
+  - Features no-frills textarea editor preserving all whitespace
+  - Added Save and Cancel buttons with proper styling
+  - Auto-focus on editor for immediate typing
+- **4. Implemented PUT API Endpoint:**
+  - Added PUT handler to `/api/wiki/*path` route for saving edited content
+  - Implemented `save_wiki_handler()` with authentication and permission validation
+  - Uses existing `WikiService.save_page()` method for file operations
+- **5. Added Git Commit Functionality:**
+  - Created `git_commit_changes()` helper function
+  - Automatically stages and commits edited files if git repository exists
+  - Includes commit message with editor username: "Update {path}\n\nEdited by: {username}"
+  - Fails silently if no git repository present (as requested)
+- **6. Helper Functions:**
+  - Added `get_user_from_headers()` to extract user from JWT tokens
+  - Made `WikiService.can_edit_page()` method public for permission checking
+- **Technical Implementation:**
+  - Uses existing authentication system (JWT tokens)
+  - Respects user role permissions (Admin/Editor can edit, Viewer cannot)
+  - Handles both Bearer token headers and auth_token cookies
+  - Proper URL encoding/decoding for nested paths
+  - JavaScript fetch API with proper error handling
+- **Result:** Complete editing workflow allowing authenticated users to edit any wiki page with automatic git versioning
