+    THE USE OF THIS DOCUMENT OR THE INFORMATION OR WORKS PROVIDED

+
+Statement of Purpose
+
+The laws of most jurisdictions throughout the world automatically confer
+exclusive Copyright and Related Rights (defined below) upon the creator
+and subsequent owner(s) (each and all, an "owner") of an original work of
+authorship and/or a database (each, a "Work").
+
+Certain owners wish to permanently relinquish those rights to a Work for
+the purpose of contributing to a commons of creative, cultural and
+scientific works ("Commons") that the public can reliably and without fear
+of later claims of infringement build upon, modify, incorporate in other
+works, reuse and redistribute as freely as possible in any form whatsoever
+and for any purposes, including without limitation commercial purposes.
+These owners may contribute to the Commons to promote the ideal of a free
+culture and the further production of creative, cultural and scientific
+works, or to gain reputation or greater distribution for their Work in
+part through the use and efforts of others.
+
+For these and/or other purposes and motivations, and without any
+expectation of additional consideration or compensation, the person
+associating CC0 with a Work (the "Affirmer"), to the extent that he or she
+is an owner of Copyright and Related Rights in the Work, voluntarily
+elects to apply CC0 to the Work and publicly distribute the Work under its
+terms, with knowledge of his or her Copyright and Related Rights in the
+Work and the meaning and intended legal effect of CC0 on those rights.
+
+1. Copyright and Related Rights. A Work made available under CC0 may be
+protected by copyright and related or neighboring rights ("Copyright and
+Related Rights"). Copyright and Related Rights include, but are not
+limited to, the following:
+
+  i. the right to reproduce, adapt, distribute, perform, display,
+     communicate, and translate a Work;
+ ii. moral rights retained by the original author(s) and/or performer(s);
+iii. publicity and privacy rights pertaining to a person's image or
+     likeness depicted in a Work;
+ iv. rights protecting against unfair competition in regards to a Work,
+     subject to the limitations in paragraph 4(a), below;
+  v. rights protecting the extraction, dissemination, use and reuse of data
+     in a Work;
+ vi. database rights (such as those arising under Directive 96/9/EC of the
+     European Parliament and of the Council of 11 March 1996 on the legal
+     protection of databases, and under any national implementation
+     thereof, including any amended or successor version of such
+     directive); and
+vii. other similar, equivalent or corresponding rights throughout the
+     world based on applicable law or treaty, and any national
+     implementations thereof.
+
+2. Waiver. To the greatest extent permitted by, but not in contravention
+of, applicable law, Affirmer hereby overtly, fully, permanently,
+irrevocably and unconditionally waives, abandons, and surrenders all of
+Affirmer's Copyright and Related Rights and associated claims and causes
+of action, whether now known or unknown (including existing as well as
+future claims and causes of action), in the Work (i) in all territories
+worldwide, (ii) for the maximum duration provided by applicable law or
+treaty (including future time extensions), (iii) in any current or future
+medium and for any number of copies, and (iv) for any purpose whatsoever,
+including without limitation commercial, advertising or promotional
+purposes (the "Waiver"). Affirmer makes the Waiver for the benefit of each
+member of the public at large and to the detriment of Affirmer's heirs and
+successors, fully intending that such Waiver shall not be subject to
+revocation, rescission, cancellation, termination, or any other legal or
+equitable action to disrupt the quiet enjoyment of the Work by the public
+as contemplated by Affirmer's express Statement of Purpose.
+
+3. Public License Fallback. Should any part of the Waiver for any reason
+be judged legally invalid or ineffective under applicable law, then the
+Waiver shall be preserved to the maximum extent permitted taking into
+account Affirmer's express Statement of Purpose. In addition, to the
+extent the Waiver is so judged Affirmer hereby grants to each affected
+person a royalty-free, non transferable, non sublicensable, non exclusive,
+irrevocable and unconditional license to exercise Affirmer's Copyright and
+Related Rights in the Work (i) in all territories worldwide, (ii) for the

+of copies, and (iv) for any purpose whatsoever, including without
+limitation commercial, advertising or promotional purposes (the
+"License"). The License shall be deemed effective as of the date CC0 was
+applied by Affirmer to the Work. Should any part of the License for any
+reason be judged legally invalid or ineffective under applicable law, such
+partial invalidity or ineffectiveness shall not invalidate the remainder
+of the License, and in such case Affirmer hereby affirms that he or she
+will not (i) exercise any of his or her remaining Copyright and Related
+Rights in the Work or (ii) assert any associated claims and causes of
+action with respect to the Work, in either case contrary to Affirmer's

+## :sparkles: What is Driftwood?
+
+**Driftwood is a graphical app manager for AppImages.** AppImages are portable
+Linux applications that come as a single file - no installation needed, no
+package manager required, no root access, no corporate app store standing between
+you and the software you want to run.
+
+But managing AppImages by hand can be confusing. Making them show up in your app
+menu, checking for updates, knowing if they're safe - that's a lot of work,
+especially if you're new to Linux.
+
+Driftwood handles all of that for you with a clean, easy-to-use interface. It
+runs entirely on your machine - nothing is sent anywhere, nothing is collected,
+nothing is monetized.
+
+---
+
+## :raising_hand: Who is this for?
+
+- **People new to Linux** who want a simple, welcoming way to manage their apps
+- **Anyone who downloads AppImages** and wants them organized, updated, and
+  integrated into their desktop without friction
+- **People who care about privacy** and want to know exactly what their apps
+  contain and whether any bundled libraries have known security issues
+- **People who believe software should be accessible to everyone** - Driftwood
+  meets WCAG 2.2 AAA accessibility standards
+- **Power users** who want a full command-line interface alongside the GUI
+
+---
+
+## :framed_picture: What does it look like?
+
+Driftwood uses GTK4 and libadwaita, so it looks and feels like a native GNOME
+app. It has three main views:
+
+| View | What it does |
+|------|-------------|
+| **Installed** | Shows all your AppImages in a grid or list with status badges |
+| **Catalog** | Browse and discover new AppImage apps from the community |
+| **Updates** | See which apps have newer versions and update them |
+
+Click any app to see its full details - version info, security status, disk
+usage, screenshots, and more.
+
+---
+
+## :star2: Features
+
+### :package: App Library
+
+- **Automatic scanning** - Driftwood finds all AppImage files in your chosen
+  folders (like `~/Applications` or `~/Downloads`)
+- **Grid and list views** - See your apps as cards with icons, or as a detailed
+  list - whichever you prefer
+- **Search and sort** - Find apps by name, sort by name, size, or when you added
+  them
+- **Tags** - Label your apps with custom tags and filter by them
+- **Selection mode** - Select multiple apps at once for batch actions
+- **Drag and drop** - Drop an AppImage file onto the window to add it
+
+### :globe_with_meridians: App Catalog
+
+- **Browse community apps** - Discover AppImage apps shared by developers and
+  communities - no walled garden, no curation fees, no gatekeeping
+- **Category filters** - Browse by Audio, Games, Graphics, Development, and more
+- **Featured apps** - A rotating carousel of highlighted apps
+- **Search** - Find apps by name across the entire catalog
+- **App details** - See descriptions, screenshots, star counts, and download
+  numbers
+- **One-click install** - Download and add apps directly from the catalog
+
+### :arrow_up: Updates
+
+- **Check for updates** - Scan all your apps for newer versions with one click
+- **Update all at once** - Or update apps individually, your choice
+- **Release notes** - See what changed in each new version before you decide
+- **Automatic backups** - Optionally save old versions before updating, so you
+  can roll back if something breaks
+- **Multiple update sources** - Works with GitHub Releases, GitLab Releases,
+  zsync delta updates, and OCS feeds
+
+### :rocket: Desktop Integration
+
+- **Add to app menu** - Make any AppImage show up in your desktop's application
+  menu with one click
+- **Icon installation** - Automatically extracts and installs the app's icon
+- **Autostart** - Set apps to launch automatically when you log in
+- **Custom launch options** - Add command-line arguments or environment variables
+  per app
+- **Fully reversible** - Remove any app from your menu just as easily as you
+  added it. Every change Driftwood makes to your system is tracked and can be
+  undone
+
+### :shield: Security
+
+Your apps shouldn't be a black box. Driftwood helps you see what's inside.
+
+- **Vulnerability scanning** - Extracts the shared libraries bundled inside each
+  AppImage and checks them against the OSV.dev vulnerability database
+- **CVE details** - Shows the severity (Critical, High, Medium, Low), CVSS
+  scores, and which library versions are affected
+- **Security report** - Generate a full report of all your apps and export it as
+  HTML, JSON, or CSV
+- **Desktop notifications** - Get notified when a new vulnerability is found in
+  one of your apps
+- **Signature verification** - Check GPG signatures and SHA256 checksums
+- **Configurable thresholds** - Choose whether to be notified about only critical
+  issues or everything
+
+### :jigsaw: FUSE and Wayland Compatibility
+
+- **FUSE detection** - Checks whether your system can mount AppImages and tells
+  you exactly what to install if it can't
+- **Guided FUSE setup** - A step-by-step wizard that shows you the right install
+  command for your distribution - no searching forums, no guesswork
+- **Wayland compatibility** - Detects whether you're running Wayland or X11 and
+  flags any compatibility concerns
+- **Fallback launching** - If FUSE isn't available, Driftwood can extract and run
+  AppImages directly - you're never locked out of your own software
+
+### :broom: Cleanup and Disk Management
+
+- **Duplicate finder** - Detects when you have multiple copies of the same app
+  or different versions taking up space, and shows how much you'd save
+- **Disk footprint** - Shows config, cache, and data folders each app has created
+  on your system - no hidden clutter
+- **Cleanup wizard** - A guided walkthrough that finds orphaned desktop entries,
+  leftover caches, and duplicates, then lets you choose what to remove
+- **Orphan cleanup** - Finds and removes menu entries for AppImages that no
+  longer exist on disk
+
+### :bar_chart: Dashboard
+
+- **System overview** - A quick health check showing FUSE status, Wayland status,
+  total apps, storage used, and apps needing updates
+- **At-a-glance stats** - Everything about your AppImage setup in one place
+
+### :gear: Preferences
+
+- **Appearance** - Follow your system's light/dark theme, or pick one
+- **Scan directories** - Choose which folders Driftwood watches for AppImages
+- **Update settings** - Configure automatic update checking, backup behavior,
+  and how long to keep old versions
+- **Security settings** - Enable automatic scanning, notifications, and set a
+  GitHub token for higher API rate limits
+- **Catalog settings** - Toggle automatic metadata enrichment and removable media
+  watching
+
+### :lock: Sandboxing
+
+- **Firejail support** - Launch apps inside a Firejail sandbox for extra
+  isolation
+- **Per-app profiles** - Each app can have its own sandbox configuration
+- **Profile management** - Use local, community, or default Firejail profiles
+
+### :wheelchair: Accessibility
+
+Software that only works for some people doesn't really work. Driftwood is built
+to meet WCAG 2.2 AAA accessibility standards:
+
+- **Full keyboard navigation** - Every single feature is reachable without a
+  mouse
+- **Screen reader support** - All buttons, images, and status changes are
+  announced to screen readers like Orca
+- **Focus management** - Clear, visible focus indicators (3px outlines) on all
+  interactive elements
+- **44px minimum target sizes** - All buttons meet the AAA touch/click target
+  standard
+- **High contrast support** - Enhanced borders and colors when your system uses
+  high contrast mode
+- **No timing requirements** - Nothing in the app requires fast reactions or
+  races against a clock
+- **Semantic roles** - Headings, alerts, status regions, and live announcements
+  are all properly marked up for assistive technology
+- **Automated testing** - Ships with an AT-SPI audit tool that walks the live
+  accessibility tree and checks for violations
+

+
+## :penguin: Which Linux distributions does it work on?
+
+Driftwood works on any Linux distribution that has GTK 4.16+ and libadwaita 1.6+.
+In practice, that means most modern distributions released from 2024 onward.
+
+| Distribution | Status | Notes |
+|-------------|--------|-------|
+| **Ubuntu 24.04+** | :white_check_mark: Works | GTK4 and libadwaita in default repos |
+| **Fedora 40+** | :white_check_mark: Works | Excellent GTK4 support out of the box |
+| **Arch Linux** | :white_check_mark: Works | Rolling release, always has the latest |
+| **Manjaro** | :white_check_mark: Works | Same packages as Arch |
+| **openSUSE Tumbleweed** | :white_check_mark: Works | Rolling release with current GTK4 |
+| **Debian Testing/Sid** | :white_check_mark: Works | Stable may have older GTK versions |
+| **Linux Mint 22+** | :white_check_mark: Works | Based on Ubuntu 24.04 |
+| **Pop!_OS 24.04+** | :white_check_mark: Works | Based on Ubuntu |
+| **elementary OS 8+** | :white_check_mark: Works | GTK4-based Pantheon desktop |
+| **Gentoo** | :white_check_mark: Works | Build from source |
+| **Alpine** | :white_check_mark: Works | GTK4 in community repos |
+| **NixOS** | :white_check_mark: Works | Package GTK4 + libadwaita via Nix |
+
+**Desktop environment**: Driftwood is designed for GNOME but works on any desktop
+that supports GTK4 applications (KDE Plasma, Cinnamon, XFCE, Budgie, Sway, etc.).
+It looks best on GNOME and GNOME-based desktops because it uses libadwaita for
+styling.

+## :open_file_folder: Where Driftwood Stores Things
+
+Driftwood keeps everything local. Nothing leaves your machine.
+
+| What | Location |
+|------|----------|
+| App database | `~/.local/share/driftwood/driftwood.db` |
+| Cached icons | `~/.local/share/driftwood/icons/` |
+| Desktop entries | `~/.local/share/applications/driftwood-*.desktop` |
+| Installed icons | `~/.local/share/icons/hicolor/` |
+| Autostart entries | `~/.config/autostart/` |
+| Settings | GSettings (`app.driftwood.Driftwood`) |
+| Backups | `~/.local/share/driftwood/backups/` |
+
+Every modification Driftwood makes to your system is recorded in its database.
+You can undo all of it at any time with `driftwood purge` or through the UI.
+Your system, your rules.

+
+## :test_tube: Accessibility Testing
+
+Driftwood ships with an automated accessibility audit tool that uses AT-SPI (the
+Linux accessibility bus) to walk the live widget tree and check for WCAG 2.2
+violations:
 
 ```sh
-# Scan configured directories for AppImages
+# Full AAA-level audit (builds and launches automatically)
-driftwood scan
+python3 tools/a11y-audit.py --level aaa
 
-# List all known AppImages
+# Attach to an already-running instance
-driftwood list
+python3 tools/a11y-audit.py --no-launch --level aaa
-driftwood list --format json
 
-# Inspect a specific AppImage
+# AA level only
-driftwood inspect ~/Applications/Firefox.AppImage
+python3 tools/a11y-audit.py --level aa
 
-# Integrate into desktop menu
+# Verbose output with live region inventory
-driftwood integrate ~/Applications/Firefox.AppImage
+python3 tools/a11y-audit.py --level aaa --verbose
-
-# Check for updates
-driftwood check-updates
-
-# Run a security scan
-driftwood security
-driftwood security ~/Applications/Firefox.AppImage
-
-# Launch with tracking
-driftwood launch ~/Applications/Firefox.AppImage
-driftwood launch --sandbox ~/Applications/Firefox.AppImage
-
-# Find duplicates
-driftwood duplicates
-
-# Show disk footprint
-driftwood footprint ~/Applications/Firefox.AppImage
-
-# System status
-driftwood status
-
-# Clean orphaned entries
-driftwood clean-orphans
 ```

-# Driftwood User Guide
-
-## Getting started
-
-### Installation
-
-**From source:**
-```sh
-cargo build --release
-sudo install -Dm755 target/release/driftwood /usr/local/bin/driftwood
-```
-
-**Arch Linux (AUR):**
-```sh
-yay -S driftwood
-```
-
-**Flatpak:**
-```sh
-flatpak install app.driftwood.Driftwood
-```
-
-### First launch
-
-When you first open Driftwood, you'll see an empty state with two options:
-
-- **Scan Now** - Immediately scan the default directories (`~/Applications` and
-  `~/Downloads`) for AppImage files
-- **Preferences** - Configure which directories to scan and other settings
-
-Driftwood will discover all AppImage files (both Type 1 and Type 2) in your
-configured directories and add them to its library.
-
-## Library view
-
-The main screen shows all your discovered AppImages in either grid or list mode.
-Toggle between views with the button in the header bar.
-
-### Status badges
-
-Each AppImage card shows colored badges indicating:
-
-- **Wayland status** - Green (native), yellow (XWayland), red (X11 only)
-- **FUSE status** - Green (native FUSE), yellow (extract-and-run), red (cannot launch)
-- **Update available** - Blue badge when a newer version is detected
-- **Security** - Red badge if known vulnerabilities are found
-
-### Searching
-
-Use the search bar to filter AppImages by name or file path. The search is
-debounced - it waits 150ms after you stop typing before filtering.
-
-### Keyboard shortcuts
-
-- **Ctrl+Q** - Quit
-- **Ctrl+D** - Open dashboard
-- **Ctrl+U** - Check for updates
-
-## Detail view
-
-Click any AppImage card to see its full detail page. The detail view has
-these sections:
-
-### Identity
-App name, version, developer, description, and categories extracted from
-the AppImage's embedded .desktop file.
-
-### Desktop integration
-Shows whether the AppImage is integrated into your desktop menu. You can
-integrate or remove integration from here.
-
-### Runtime compatibility
-FUSE status (how the AppImage can be mounted) and Wayland compatibility
-(whether the app supports Wayland natively or needs XWayland).
-
-### Sandboxing
-Toggle Firejail sandboxing for this AppImage. When enabled, the app
-launches inside a Firejail container with `--appimage` flag. Requires
-firejail to be installed.
-
-### Updates
-Shows the update type (GitHub Releases, GitLab, zsync), current and latest
-versions, and lets you check for and apply updates.
-
-### Usage
-Launch count and last launched date.
-
-### Security
-Results of CVE scanning against bundled libraries. Shows counts by severity
-(critical, high, medium, low).
-
-### Disk footprint
-Config, data, and cache directories associated with this AppImage. Shows
-estimated size and discovery confidence.
-
-### File details
-File path, size, SHA256 hash, AppImage type, architecture, and timestamps.
-
-## Scanning
-
-### Automatic scanning
-By default, Driftwood scans on startup. Disable this in Preferences under
-Behavior > "Scan on startup".
-
-### Manual scanning
-Use the "Scan for AppImages" option in the hamburger menu or run:
-```sh
-driftwood scan
-```
-
-### Scan optimization
-On subsequent scans, Driftwood skips files that haven't changed (same size
-and modification time) and already have all analysis complete. This makes
-re-scans much faster.
-
-### Adding scan directories
-Go to Preferences > General > Scan Locations to add or remove directories.
-Subdirectories are not scanned recursively.
-
-## Desktop integration
-
-Driftwood creates standard .desktop files in `~/.local/share/applications/`
-with the prefix `driftwood-`. Icons are installed to
-`~/.local/share/icons/hicolor/`.
-
-To integrate an AppImage:
-1. Open its detail view
-2. Click "Integrate" in the Desktop Integration section
-3. Confirm in the integration dialog
-
-To remove integration:
-1. Open its detail view
-2. Click "Remove Integration"
-
-## Updates
-
-### Checking for updates
-- Single app: Open detail view and click "Check for Updates"
-- All apps: Use the hamburger menu "Check for Updates" or `driftwood check-updates`
-
-### Applying updates
-When an update is available, click "Update Now" in the update dialog. Driftwood
-downloads the new version and replaces the old file.
-
-### Old version cleanup
-After a successful update, Driftwood handles the old version based on your
-preference (Preferences > Behavior > "After updating an AppImage"):
-
-- **Ask each time** (default) - Shows a dialog asking whether to remove the backup
-- **Remove old version** - Automatically deletes the backup
-- **Keep backup** - Saves the old version with a `.old` extension
-
-## Security scanning
-
-Driftwood extracts the list of shared libraries (.so files) bundled inside each
-AppImage and queries the OSV.dev vulnerability database for known CVEs.
-
-### Running a scan
-- Single app: Open detail view and click "Run Security Scan"
-- All apps: `driftwood security`
-- Single app CLI: `driftwood security ~/path/to/app.AppImage`
-
-### Interpreting results
-Results show CVE IDs grouped by severity. Each CVE includes:
-- CVE identifier and severity level
-- CVSS score (if available)
-- Summary of the vulnerability
-- Affected library and version
-- Fixed version (if known)
-
-### Limitations
-- Not all bundled libraries can be identified
-- Version detection uses heuristics and may be inaccurate
-- Results should be treated as advisory, not definitive
-
-## Duplicate detection
-
-Driftwood detects:
-- **Same app, different versions** - Multiple version files of the same application
-- **Identical files** - Same SHA256 hash in different locations
-
-Access via the hamburger menu "Find Duplicates" or `driftwood duplicates`.
-
-## Disk cleanup
-
-The cleanup wizard (hamburger menu > "Disk Cleanup") helps reclaim space by:
-- Identifying orphaned desktop entries for deleted AppImages
-- Finding associated config/data/cache directories
-- Showing total reclaimable space
-
-## Orphaned entries
-
-When an AppImage is deleted outside of Driftwood, its .desktop file and icon
-remain. Driftwood detects these orphans and offers to clean them up.
-
-- Automatic detection on the dashboard
-- Manual cleanup via hamburger menu or `driftwood clean-orphans`
-
-## Dashboard
-
-The dashboard (Ctrl+D or hamburger menu) shows system health:
-- FUSE availability (fuse2, fuse3, or none)
-- Wayland session information
-- Total disk usage by AppImages
-- Orphaned entry count
-- Security alert summary
-

-# AppImage Comprehensive Metadata Extraction and Display
-
-## Goal
-
-Extract ALL available metadata from AppImage files - from the oldest Type 1 format to the newest Type 2 with AppStream XML - and display it comprehensively in the overview tab of the detail view.
-
-## Background: All AppImage Metadata Sources
-
-### 1. ELF Binary Header (Type 1 and Type 2)
-- Magic bytes at offset 8: `AI\x01` (Type 1) or `AI\x02` (Type 2)
-- Architecture from `e_machine` at offset 18
-
-### 2. Type 1: ISO 9660 Volume Descriptor
-- Update info at fixed offset 33651 (512 bytes)
-
-### 3. Type 2: ELF Sections
-- `.upd_info` (1024 bytes) - update transport (zsync, GitHub releases, etc.)
-- `.sha256_sig` (1024 bytes) - GPG digital signature
-- `.sig_key` (8192 bytes) - public key for signature verification
-
-### 4. Desktop Entry File (.desktop)
-Standard freedesktop fields:
-- `Name`, `GenericName`, `Comment`, `Icon`, `Exec`, `Categories`
-- `Keywords`, `MimeType`, `StartupWMClass`, `Terminal`
-- `Actions` with `[Desktop Action <name>]` sections
-- AppImage-specific: `X-AppImage-Version`, `X-AppImage-Name`, `X-AppImage-Arch`
-
-### 5. AppStream / AppData XML (richest source)
-Located at `usr/share/metainfo/*.xml` or `usr/share/appdata/*.xml`:
-- `<id>` - reverse-DNS identifier
-- `<name>` - localized app name
-- `<summary>` - one-line description
-- `<description>` - full rich-text description
-- `<developer>` - developer/organization
-- `<project_license>` - SPDX license
-- `<project_group>` - umbrella project (GNOME, KDE, etc.)
-- `<url type="...">` - homepage, bugtracker, donation, help, vcs-browser, contribute
-- `<keywords>` - search terms
-- `<categories>` - menu categories
-- `<screenshots>` - screenshot URLs with captions
-- `<releases>` - version history with dates and changelogs
-- `<content_rating type="oars-1.1">` - age rating
-- `<provides>` - MIME types, binaries, D-Bus interfaces
-- `<branding>` - theme colors
-
-### 6. Icons (already handled)
-- `.DirIcon`, root-level PNG/SVG, `usr/share/icons/` hierarchy
-
-### 7. Digital Signatures (Type 2)
-- GPG signature in `.sha256_sig` ELF section
-- Verifiable with embedded public key
-
-## Approach
-
-Parse everything at analysis time and store in the database (Approach A). This matches the existing architecture where `run_background_analysis()` populates the DB and the UI reads from `AppImageRecord`.
-
-## Database Schema (Migration v9)
-
-16 new columns on `appimages`:
-
-| Column | Type | Default | Description |
-|--------|------|---------|-------------|
-| `appstream_id` | TEXT | NULL | Reverse-DNS ID (e.g. `org.kde.krita`) |
-| `appstream_description` | TEXT | NULL | Rich description (paragraphs joined with newlines) |
-| `generic_name` | TEXT | NULL | Generic descriptor ("Web Browser") |
-| `license` | TEXT | NULL | SPDX license expression |
-| `homepage_url` | TEXT | NULL | Project website |
-| `bugtracker_url` | TEXT | NULL | Bug reporting URL |
-| `donation_url` | TEXT | NULL | Donation page |
-| `help_url` | TEXT | NULL | Documentation URL |
-| `vcs_url` | TEXT | NULL | Source code URL |
-| `keywords` | TEXT | NULL | Comma-separated keywords |
-| `mime_types` | TEXT | NULL | Semicolon-separated MIME types |
-| `content_rating` | TEXT | NULL | Summarized OARS rating |
-| `project_group` | TEXT | NULL | Umbrella project |
-| `release_history` | TEXT | NULL | JSON array of recent releases |
-| `desktop_actions` | TEXT | NULL | JSON array of desktop actions |
-| `has_signature` | INTEGER | 0 | Whether AppImage has GPG signature |
-
-## New Module: AppStream XML Parser
-
-**File:** `src/core/appstream.rs`
-
-Uses `quick-xml` crate (pure Rust, lightweight).
-
-Key types:
-```
-AppStreamMetadata
-  id: Option<String>
-  name: Option<String>
-  summary: Option<String>
-  description: Option<String>
-  developer: Option<String>
-  project_license: Option<String>
-  project_group: Option<String>
-  urls: HashMap<String, String>
-  keywords: Vec<String>
-  categories: Vec<String>
-  content_rating_summary: Option<String>
-  releases: Vec<ReleaseInfo>
-  mime_types: Vec<String>
-
-ReleaseInfo
-  version: String
-  date: Option<String>
-  description: Option<String>
-```
-
-Parser function: `parse_appstream_file(path: &Path) -> Option<AppStreamMetadata>`
-- Walks XML events, extracts all fields
-- Strips HTML from `<description>` (joins `<p>` with newlines, `<li>` with bullets)
-- Caps releases at 10 most recent
-- Summarizes OARS content rating into a single label
-
-## Extended Desktop Entry Parsing
-
-Update `DesktopEntryFields` in `inspector.rs`:
-- Add `generic_name`, `keywords`, `mime_types`, `terminal`, `actions`, `x_appimage_name`
-- Parse `[Desktop Action <name>]` sections for action names and exec commands
-
-## Inspector + Analysis Pipeline
-
-1. `AppImageMetadata` struct gains all new fields
-2. `inspect_appimage()` looks for AppStream XML after extraction, parses it, merges into metadata (AppStream takes priority for overlapping fields)
-3. `run_background_analysis()` stores new fields via `db.update_appstream_metadata()`
-4. Signature detection: read ELF `.sha256_sig` section, check if non-empty
-
-## Overview Tab UI Layout
-
-Groups in order (each only shown when data exists):
-
-### About (new)
-- App ID, Generic name, Developer, License, Project group
-
-### Description (new)
-- Full multi-paragraph AppStream description
-
-### Links (new)
-- Homepage, Bug tracker, Source code, Documentation, Donate
-- Each row clickable via `gtk::UriLauncher`
-
-### Updates (existing, unchanged)
-
-### Release History (new)
-- Recent releases with version, date, description
-- Uses `adw::ExpanderRow` for entries with descriptions
-
-### Usage (existing, unchanged)
-
-### Capabilities (new)
-- Keywords, MIME types, Content rating, Desktop actions
-
-### File Information (existing, extended)
-- Add "Signature: Signed / Not signed" row
-
-## Dependencies
-
-Add to `Cargo.toml`:
-```toml
-quick-xml = "0.37"
-```
-
-## Files Modified
-
-| File | Changes |
-|------|---------|
-| `Cargo.toml` | Add `quick-xml` |
-| `src/core/mod.rs` | Add `pub mod appstream;` |
-| `src/core/appstream.rs` | **New** - AppStream XML parser |
-| `src/core/database.rs` | Migration v9, new columns, `update_appstream_metadata()` |
-| `src/core/inspector.rs` | Extended desktop parsing, AppStream integration, signature detection |
-| `src/core/analysis.rs` | Store new metadata fields |
-| `src/ui/detail_view.rs` | Redesigned overview tab with all new groups |
-
-## Verification
-
-1. `cargo build` compiles without errors
-2. AppImages with AppStream XML show full metadata (developer, license, URLs, releases)
-3. AppImages without AppStream XML still show desktop entry fields (graceful degradation)
-4. URL links open in browser
-5. Release history is scrollable/expandable
-6. Empty groups are hidden
-7. Re-scanning an app picks up newly available metadata

-# Audit Fixes Design
-
-## Goal
-
-Fix all 29 findings from the full codebase audit, organized by severity tier with build verification between tiers.
-
-## Approach
-
-Fix by severity tier (Critical -> High -> Medium -> Low). Run `cargo build` after each tier to catch regressions early.
-
-## Tier 1: Critical (5 items)
-
-### #1 - security.rs: Fix unsquashfs argument order
-`detect_version_from_binary` passes `appimage_path` after the extract pattern. unsquashfs expects the archive before patterns. Move `appimage_path` before the file pattern, remove the `-e` flag.
-
-### #2 - integrator.rs: Quote Exec path in .desktop files
-`Exec={exec} %U` breaks for paths with spaces. Change to `Exec="{exec}" %U`.
-
-### #3 - duplicates.rs: Fix compare_versions total order
-`compare_versions("1.0", "v1.0")` returns `Less` both ways (violates antisymmetry). Use `clean_version()` on both inputs for the equality check.
-
-### #4 - inspector.rs: Chunk-based signature detection
-`detect_signature` reads entire files (1.5GB+) into memory. Replace with `BufReader` reading 64KB chunks, scanning each for the signature bytes.
-
-### #5 - updater.rs: Read only first 12 bytes in verify_appimage
-Replace `fs::read(path)` with `File::open` + `read_exact` for just the ELF/AI magic bytes.
-
-## Tier 2: High (6 items)
-
-### #6 - database.rs: Handle NULL severity in CVE summaries
-`get_cve_summary` and `get_all_cve_summary` fail on NULL severity. Change to `Option<String>`, default `None` to `"MEDIUM"`.
-
-### #7 - inspector.rs: Fix deadlock in extract_metadata_files
-Piped stderr + `.status()` can deadlock. Change to `Stdio::null()` since we don't use stderr.
-
-### #8 - updater.rs: Fix glob_match edge case
-After matching the last part with `ends_with`, reduce the search text before checking middle parts.
-
-### #9 - backup.rs: Prevent archive filename collisions
-Use relative paths from home directory instead of bare filenames, so two dirs with the same leaf name don't collide.
-
-### #10 - launcher.rs: Async crash detection
-Remove the 1.5s blocking sleep from `execute_appimage`. Return `Started` immediately with the `Child`. Callers (already async) handle crash detection by polling the child after a delay.
-
-### #11 - launcher.rs: Drop stderr pipe on success
-After returning `Started`, either drop `child.stderr` or use `Stdio::null()` for stderr to prevent pipe buffer deadlock on long-running apps.
-
-## Tier 3: Medium (9 items)
-
-### #12 - window.rs: Gate scan on auto-scan-on-startup
-Wrap `self.trigger_scan()` in `if self.settings().boolean("auto-scan-on-startup")`.
-
-### #13 - window.rs: Fix window size persistence
-Change `self.default_size()` to `(self.width(), self.height())`.
-
-### #14 - widgets.rs: Fix announce() for any container
-Change `announce()` to not require a `gtk::Box` - use a more generic approach or fix callers to pass the correct widget type.
-
-### #15 - detail_view.rs: Claim gesture in lightbox
-Add `gesture.set_state(gtk::EventSequenceState::Claimed)` in the picture click handler.
-
-### #16 - cli.rs: Use serde_json for JSON output
-Replace hand-crafted `format!` JSON with `serde_json::json!()`.
-
-### #17 - style.css: Remove dead @media blocks
-Delete `@media (prefers-color-scheme: dark)` and `@media (prefers-contrast: more)` blocks. libadwaita named colors already adapt.
-
-### #18 - gschema.xml + detail_view.rs: Wire detail-tab persistence
-Save active tab on switch, restore on open.
-
-### #19 - metainfo.xml: Remove invalid categories
-Delete `<categories>` block (already in .desktop file, invalid in metainfo per AppStream spec).
-
-### #20 - fuse.rs: Byte-level search
-Replace `String::from_utf8_lossy().to_lowercase()` with direct byte-level case-insensitive search using `windows()`.
-
-## Tier 4: Low (9 items)
-
-### #21 - wayland.rs: Tighten env var detection
-Remove `WAYLAND_DISPLAY` from fallback heuristic. Keep only `GDK_BACKEND` and `QT_QPA_PLATFORM`.
-
-### #22 - inspector.rs: Add ELF magic validation
-Check `\x7fELF` magic and endianness byte before parsing `e_machine`.
-
-### #23 - updater.rs: Add timeout to extract_update_info_runtime
-Add 5-second timeout to prevent indefinite blocking.
-
-### #24 - launcher.rs: Handle quoted args
-Use a shell-like tokenizer that respects double-quoted strings in `parse_launch_args`.
-
-### #25 - (merged with #20)
-
-### #26 - window.rs: Stop watcher timer on window destroy
-Return `glib::ControlFlow::Break` when `window_weak.upgrade()` returns `None`.
-
-### #27 - gschema.xml: Add choices/range constraints
-Add `<choices>` to enumerated string keys, `<range>` to backup-retention-days.
-
-### #28 - style.css: Remove unused CSS classes
-Delete `.quick-action-pill`, `.badge-row`, `.detail-view-switcher`, base `.letter-icon`.
-
-### #29 - style.css/app_card.rs: Fix status-ok/status-attention
-Define CSS rules for these classes or remove the class additions from code.
-
-## Verification
-
-After each tier: `cargo build` with zero errors and zero warnings. After all tiers: manual app launch test.

-# Beginner-Friendly Copy Overhaul - Design
-
-**Goal:** Rewrite all technical jargon in the detail view into plain language that newcomers can understand, while keeping technical details available in tooltips.
-
-**Approach:** Friendly titles/subtitles for everyone, technical details on hover. Terminal commands stay copyable but with softer framing ("Install with one command" instead of showing the raw command as a subtitle).
-
-**Scope:** detail_view.rs (all 4 tabs), security_report.rs, fuse_user_explanation(), wayland_user_explanation()

-# Driftwood Feature Roadmap - Design Document
-
-**Goal:** Add 26 features to make Driftwood the definitive AppImage manager for Linux newcomers coming from Windows, covering the full lifecycle from discovery to clean uninstall.
-
-**Architecture:** All features build on the existing GTK4/libadwaita/Rust stack. Every system modification (desktop files, icons, MIME associations, autostart entries) is tracked in a central `system_modifications` table and fully reversed on app removal. Features are ordered from simplest to most complex.
-
-**Tech Stack:** Rust, gtk4-rs, libadwaita-rs, rusqlite, gio, notify crate, pkexec/polkit for privileged operations, XDG specs (Desktop Entry, Autostart, MIME Applications), AppImage feed.json catalog.
-
----
-
-## Core Architecture: System Modification Tracking
-
-Every feature that touches system files MUST use this tracking system. No exceptions.
-
-### New Database Table
-
-```sql
-CREATE TABLE IF NOT EXISTS system_modifications (
-    id              INTEGER PRIMARY KEY AUTOINCREMENT,
-    appimage_id     INTEGER REFERENCES appimages(id) ON DELETE CASCADE,
-    mod_type        TEXT NOT NULL,
-    file_path       TEXT NOT NULL,
-    previous_value  TEXT,
-    created_at      TEXT NOT NULL DEFAULT (datetime('now'))
-);
-CREATE INDEX IF NOT EXISTS idx_system_mods_appimage
-    ON system_modifications(appimage_id);
-```
-
-**mod_type values:** `desktop_file`, `icon`, `autostart`, `mime_default`, `mime_entry`, `system_desktop`, `system_icon`, `system_binary`
-
-### Core Functions (src/core/integrator.rs)
-
-```rust
-pub fn register_modification(db: &Database, appimage_id: i64, mod_type: &str, file_path: &str, previous_value: Option<&str>) -> Result<()>
-pub fn undo_modification(db: &Database, mod_id: i64) -> Result<()>
-pub fn undo_all_modifications(db: &Database, appimage_id: i64) -> Result<()>
-```
-
-### Uninstall Flow
-
-1. Query `system_modifications` for the appimage_id
-2. For each modification (in reverse order):
-   - `desktop_file` / `autostart` / `icon`: delete the file
-   - `mime_default`: restore previous_value via `xdg-mime default {previous_value} {mime_type}`
-   - `system_*`: delete via `pkexec rm`
-3. Run `update-desktop-database ~/.local/share/applications/`
-4. Run `gtk-update-icon-cache ~/.local/share/icons/hicolor/` (if icons were removed)
-5. Optionally delete app data paths (with user confirmation)
-6. Delete the AppImage file
-7. Delete DB record (CASCADE handles system_modifications rows)
-
-### CLI Purge Command
-
-`driftwood purge` - removes ALL system modifications for ALL managed apps, for when Driftwood itself is being removed from the system.
-
----
-
-## Feature Specifications (Sorted: Easiest to Most Complex)
-
----
-
-### F1. Auto-Set Executable Permission on Existing Files
-
-**Complexity:** Trivial (15 min)
-**Problem:** Files already in scan directories skip chmod during drag-and-drop. Non-executable AppImages found during scan aren't fixed.
-**Files:** `src/ui/drop_dialog.rs`, `src/core/discovery.rs`
-
-**Changes:**
-- `drop_dialog.rs`: In the `in_scan_dir` branch of `register_dropped_files()`, add permission check and fix:
-  ```rust
-  if !std::os::unix::fs::PermissionsExt::mode(&metadata.permissions()) & 0o111 != 0 {
-      std::fs::set_permissions(&final_path, std::fs::Permissions::from_mode(0o755))?;
-  }
-  ```
-- `discovery.rs`: After scan finds a non-executable AppImage, auto-fix permissions and log it
-
----
-
-### F2. Move-or-Copy Option for Drag-and-Drop (+ Keep in Place)
-
-**Complexity:** Easy (30 min)
-**Problem:** Always copies file, wasting disk. No option to keep in place.
-**Files:** `src/ui/drop_dialog.rs`
-
-**Changes:**
-- Replace 3-button dialog with 4 response options:
-  - `"cancel"` - Cancel
-  - `"keep-in-place"` - Keep in place (register at current location, set executable, no copy)
-  - `"copy-only"` - Copy to Applications (current "Just add" behavior)
-  - `"copy-and-integrate"` - Copy & add to menu (current "Add to app menu", suggested/default)
-- `register_dropped_files()` receives a new `copy_mode` enum: `KeepInPlace`, `CopyOnly`, `CopyAndIntegrate`
-- `KeepInPlace`: set executable on original path, register in DB at original location, optionally integrate
-- Dialog text updated: "Where should this AppImage live?"
-
----
-
-### F3. Version Rollback
-
-**Complexity:** Easy (1 hr)
-**Problem:** No way to go back if an update breaks things.
-**Files:** `src/core/updater.rs`, `src/ui/detail_view.rs`, `src/core/database.rs`
-
-**Changes:**
-- New DB column: `previous_version_path TEXT` on appimages
-- In `updater.rs` update flow: before replacing, rename old to `{path}.prev` and store path in `previous_version_path`
-- Detail view system tab: "Rollback to previous version" button (visible only when `previous_version_path` is set)
-- Rollback: swap current and .prev files, update DB fields, re-run analysis
-- Cleanup: delete .prev file when user explicitly confirms or after configurable retention
-
----
-
-### F4. Source Tracking
-
-**Complexity:** Easy (1 hr)
-**Problem:** Users can't tell where an AppImage was downloaded from.
-**Files:** `src/ui/detail_view.rs`, `src/core/database.rs`, `src/ui/drop_dialog.rs`
-
-**Changes:**
-- New DB column: `source_url TEXT` on appimages
-- Auto-detect from `update_info` field (already stored): parse GitHub/GitLab URLs
-- Display "Source: github.com/obsidianmd/obsidian" on detail view overview tab
-- Drop dialog: optional "Where did you download this?" text field (pre-filled if detected)
-- Catalog installs (F26): automatically set source_url from catalog entry
-
----
-
-### F5. Launch Statistics Dashboard
-
-**Complexity:** Easy (1-2 hrs)
-**Problem:** Launch data is tracked but never shown.
-**Files:** `src/ui/dashboard.rs`, `src/core/database.rs`
-
-**Changes:**
-- New DB queries:
-  - `get_top_launched(limit: i32) -> Vec<(String, u64)>` - most launched apps
-  - `get_launch_count_since(since: &str) -> u64` - total launches since date
-  - `get_recent_launches(limit: i32) -> Vec<(String, String)>` - recent launch events with timestamps
-- Dashboard: new "Activity" section showing:
-  - Top 5 most-launched apps with launch counts
-  - "X launches this week" summary stat
-  - "Last launched: AppName, 2 hours ago"
-
----
-
-### F6. Batch Operations
-
-**Complexity:** Medium (2-3 hrs)
-**Problem:** Can't select multiple AppImages for bulk actions.
-**Files:** `src/ui/library_view.rs`, `src/ui/app_card.rs`, `src/window.rs`
-
-**Changes:**
-- Library view header: "Select" toggle button
-- When active: app cards show checkboxes, bottom action bar slides up
-- Action bar buttons: "Integrate" / "Remove Integration" / "Delete" / "Export"
-- Each action confirms with count: "Integrate 5 AppImages?"
-- Delete uses the full uninstall flow (F14/system_modifications cleanup)
-- Selection state stored in a `HashSet<i64>` of record IDs on the LibraryView
-
----
-
-### F7. Automatic Desktop Integration on Scan
-
-**Complexity:** Easy (30 min)
-**Problem:** Users forget to integrate after scanning.
-**Files:** `src/window.rs`, `src/ui/preferences.rs`
-
-**Changes:**
-- GSettings key `auto-integrate` already exists (default false)
-- Wire it up: after scan completes in `window.rs`, if setting is true, iterate newly discovered apps and call `integrator::integrate()` for each
-- Register all created files via `register_modification()`
-- Preferences: add toggle in Behavior page (already may be there, verify)
-
----
-
-### F8. Autostart Manager
-
-**Complexity:** Medium (2 hrs)
-**Problem:** No way to set AppImages to start at login.
-**Spec:** XDG Autostart - `.desktop` file in `~/.config/autostart/`
-**Files:** `src/core/integrator.rs`, `src/ui/detail_view.rs`, `src/core/database.rs`
-
-**Changes:**
-- New DB column: `autostart INTEGER NOT NULL DEFAULT 0`
-- New functions in `integrator.rs`:
-  ```rust
-  pub fn enable_autostart(db: &Database, record: &AppImageRecord) -> Result<PathBuf>
-  pub fn disable_autostart(db: &Database, record_id: i64) -> Result<()>
-  ```
-- `enable_autostart`: creates `~/.config/autostart/driftwood-{id}.desktop` with:
-  ```ini
-  [Desktop Entry]
-  Type=Application
-  Name={app_name}
-  Exec={appimage_path}
-  Icon={icon_path}
-  X-GNOME-Autostart-enabled=true
-  X-Driftwood-AppImage-ID={id}
-  ```
-- Registers modification with mod_type `autostart`
-- Detail view system tab: "Start at login" switch row
-- `disable_autostart`: deletes the file, removes from system_modifications
-- Uninstall flow: handled by `undo_all_modifications()`
-
----
-
-### F9. System Notification Integration
-
-**Complexity:** Medium (2 hrs)
-**Problem:** Toasts vanish, important events get missed.
-**Files:** `src/core/notification.rs`, `src/window.rs`
-
-**Changes:**
-- Use `gio::Application::send_notification(id, notification)` for:
-  - App crash on launch (high priority)
-  - Updates available after background check (normal priority)
-  - Security vulnerabilities found (high priority if critical/high severity)
-- Keep toasts for minor confirmations (copied, integrated, etc.)
-- Notification click opens Driftwood and navigates to relevant view
-- `notification.rs` already has the logic for CVE notifications - extend to use gio::Notification instead of/in addition to libnotify
-
----
-
-### F10. Storage Dashboard per App
-
-**Complexity:** Medium (2 hrs)
-**Problem:** Users don't know total disk usage per app.
-**Files:** `src/ui/detail_view.rs`, `src/core/footprint.rs`, `src/core/database.rs`
-
-**Changes:**
-- `footprint.rs`: new function `get_total_footprint(db: &Database, record_id: i64) -> FootprintSummary`
-  ```rust
-  pub struct FootprintSummary {
-      pub binary_size: u64,
-      pub config_size: u64,
-      pub cache_size: u64,
-      pub data_size: u64,
-      pub state_size: u64,
-      pub total_size: u64,
-  }
-  ```
-- Detail view storage tab: visual breakdown with labeled size bars
-- Each category shows path and size: "Config (~/.config/MyApp) - 12 MB"
-- "Clean cache" button per category (deletes cache paths only)
-- Library list view: optional "Total size" column
-
----
-
-### F11. Background Update Checks
-
-**Complexity:** Medium (2-3 hrs)
-**Problem:** No automatic update awareness.
-**Files:** `src/window.rs`, `src/ui/dashboard.rs`, `src/ui/library_view.rs`, GSettings schema
-
-**Changes:**
-- New GSettings key: `update-check-interval-hours` type i, default 24, range 1-168
-- New GSettings key: `last-update-check` type s, default ''
-- On startup: if `auto-check-updates` is true and enough time has passed, spawn background check
-- Background check: iterate all apps with update_info, call `check_appimage_for_update()` per app
-- Results: update `update_available` column in DB, send gio::Notification if updates found
-- Dashboard: show "X updates available" with timestamp "Last checked: 2h ago"
-- Library view: badge on apps with updates
-- Preferences: toggle + interval dropdown
-
----
-
-### F12. One-Click Update All
-
-**Complexity:** Medium (3-4 hrs)
-**Problem:** Can only update one app at a time.
-**Files:** `src/ui/dashboard.rs`, new `src/ui/batch_update_dialog.rs`, `src/core/updater.rs`
-
-**Changes:**
-- Dashboard: "Update All (N)" button when updates are available
-- Opens batch update dialog showing list of apps to update with checkboxes
-- Progress: per-app progress bar, overall progress bar
-- Each update: download new version, save old as .prev (F3 rollback), replace, re-analyze
-- On completion: summary toast "Updated 5 apps successfully, 1 failed"
-- Failed updates: show error per app, keep old version
-- Cancel: stops remaining updates, already-updated apps stay updated
-
----
-
-### F13. Full Uninstall with Data Cleanup
-
-**Complexity:** Medium (3 hrs)
-**Problem:** Deleting AppImage leaves config/cache/data behind.
-**Files:** `src/ui/detail_view.rs`, new confirmation dialog logic, `src/core/footprint.rs`
-
-**Changes:**
-- Delete button in detail view triggers new uninstall flow:
-  1. Show dialog with FootprintSummary (from F10):
-     - "Delete MyApp?" with breakdown:
-     - [x] AppImage file (245 MB)
-     - [x] Configuration (~/.config/MyApp) - 12 MB
-     - [x] Cache (~/.cache/MyApp) - 89 MB
-     - [x] Data (~/.local/share/MyApp) - 1.2 GB
-     - Total: 1.5 GB will be freed
-  2. All checked by default, user can uncheck to keep data
-  3. On confirm:
-     - Call `undo_all_modifications()` (removes .desktop, icons, autostart, MIME defaults)
-     - Delete selected data paths
-     - Delete the AppImage file
-     - Remove DB record
-- Batch delete (F6) uses same flow with aggregated summary
-
----
-
-### F14. Theme/Icon Preview in Drop Dialog
-
-**Complexity:** Medium (2 hrs)
-**Problem:** Users don't see what the app looks like before integrating.
-**Files:** `src/ui/drop_dialog.rs`, `src/core/inspector.rs`
-
-**Changes:**
-- New function in inspector: `extract_icon_fast(path: &Path) -> Option<PathBuf>`
-  - Runs `unsquashfs -l` to find icon file, then extracts just that one file
-  - Much faster than full inspection
-- Drop dialog: after registration, show preview card:
-  - App icon (from fast extraction)
-  - App name (from filename initially, updated after full analysis)
-  - "This is how it will appear in your app menu"
-- If icon extraction fails, show default AppImage icon
-
----
-
-### F15. FUSE Fix Wizard
-
-**Complexity:** Significant (4-5 hrs)
-**Problem:** #1 support issue - FUSE not installed, AppImages won't run.
-**Files:** `src/core/fuse.rs`, new `src/ui/fuse_wizard.rs`, `src/ui/dashboard.rs`, new `data/app.driftwood.Driftwood.policy`
-
-**Changes:**
-- New distro detection in `fuse.rs`:
-  ```rust
-  pub struct DistroInfo {
-      pub id: String,         // "ubuntu", "fedora", "arch", etc.
-      pub id_like: Vec<String>,
-      pub version_id: String,
-  }
-  pub fn detect_distro() -> Option<DistroInfo>  // parses /etc/os-release
-  pub fn get_fuse_install_command(distro: &DistroInfo) -> Option<String>
-  ```
-- Install commands by distro family:
-  - Debian/Ubuntu: `apt install -y libfuse2t64` (24.04+) or `apt install -y libfuse2` (older)
-  - Fedora/RHEL: `dnf install -y fuse-libs`
-  - Arch/Manjaro: `pacman -S --noconfirm fuse2`
-  - openSUSE: `zypper install -y libfuse2`
-- Polkit policy file (`data/app.driftwood.Driftwood.policy`):
-  ```xml
-  <?xml version="1.0" encoding="UTF-8"?>
-  <!DOCTYPE policyconfig PUBLIC
-   "-//freedesktop//DTD PolicyKit Policy Configuration 1.0//EN"
-   "https://www.freedesktop.org/standards/PolicyKit/1/policyconfig.dtd">
-  <policyconfig>
-    <action id="app.driftwood.Driftwood.install-fuse">
-      <description>Install FUSE library for AppImage support</description>
-      <message>Authentication is required to install the FUSE library</message>
-      <defaults>
-        <allow_any>auth_admin</allow_any>

-        <allow_active>auth_admin</allow_active>
-      </defaults>
-    </action>
-  </policyconfig>
-  ```
-- Wizard dialog (NavigationPage-style multi-step):
-  1. "FUSE is not installed" - explanation of what FUSE is and why it's needed
-  2. "We detected {distro}. Install with: `{command}`" - shows exact command
-  3. "Install now" button runs `pkexec sh -c "{command}"` and shows output
-  4. Re-check: calls `detect_system_fuse()` and shows success/failure
-- Dashboard: yellow banner when FUSE is missing with "Fix now" button
-
----
-
-### F16. File Type Association Manager
-
-**Complexity:** Significant (4 hrs)
-**Problem:** AppImages don't register MIME types, so files don't open with them.
-**Spec:** XDG MIME Applications - `~/.local/share/applications/mimeapps.list`
-**Files:** `src/core/integrator.rs`, `src/ui/detail_view.rs`
-
-**Changes:**
-- `inspector.rs` already extracts desktop entry content including MimeType= field
-- New function: `parse_mime_types(desktop_entry: &str) -> Vec<String>` - extracts MimeType= values
-- When integrating: include `MimeType=` in generated .desktop file
-- Detail view overview tab: "Supported file types" section listing MIME types
-- Per-type toggle: "Set as default for .png files"
-- Setting default:
-  1. Query current default: `xdg-mime query default {mime_type}`
-  2. Store in `system_modifications` with `previous_value` = current default
-  3. Set new: `xdg-mime default driftwood-{id}.desktop {mime_type}`
-- Removing: restore previous default from `previous_value`
-- Uninstall: handled by `undo_all_modifications()`
-
----
-
-### F17. Taskbar/Panel Icon Fix (StartupWMClass)
-
-**Complexity:** Significant (3 hrs)
-**Problem:** Running AppImages show wrong/generic icon in taskbar.
-**Files:** `src/core/integrator.rs`, `src/core/wayland.rs`, `src/ui/detail_view.rs`
-
-**Changes:**
-- During inspection: extract `StartupWMClass=` from embedded .desktop entry
-- Store in new DB column: `startup_wm_class TEXT`
-- When generating .desktop file for integration, include StartupWMClass if available
-- After launch + Wayland analysis: read `/proc/{pid}/environ` for `GDK_BACKEND`, check window list via `xdotool` or `xprop` for WM_CLASS
-- If WM_CLASS doesn't match StartupWMClass: log warning, offer to patch .desktop file
-- Detail view system tab: show detected WM_CLASS, allow manual override
-
----
-
-### F18. Download Verification Helper
-
-**Complexity:** Significant (4 hrs)
-**Problem:** No way to verify AppImage authenticity.
-**Files:** New `src/core/verification.rs`, `src/ui/detail_view.rs`, `src/ui/drop_dialog.rs`
-
-**Changes:**
-- AppImage signature spec: GPG signature embedded at offset stored in ELF section
-- New module `verification.rs`:
-  ```rust
-  pub enum VerificationStatus {
-      SignedValid { signer: String },
-      SignedInvalid { reason: String },
-      Unsigned,
-      ChecksumMatch,
-      ChecksumMismatch,
-      NotChecked,
-  }
-  pub fn check_embedded_signature(path: &Path) -> VerificationStatus
-  pub fn verify_sha256(path: &Path, expected: &str) -> VerificationStatus
-  ```
-- `check_embedded_signature`: runs `unsquashfs -l` to check for `.sha256` or signature files, or uses the AppImage --appimage-signature flag
-- Drop dialog: after adding, show verification badge
-- Detail view: "Verification: Signed by ..." or "Unsigned - verify manually"
-- Manual verification: paste SHA256 hash, compare with computed hash
-- New DB column: `verification_status TEXT` on appimages
-
----
-
-### F19. First-Run Permission Summary
-
-**Complexity:** Medium (3 hrs)
-**Problem:** Users don't know what an AppImage can access before running it.
-**Files:** New `src/ui/permission_dialog.rs`, `src/ui/detail_view.rs`
-
-**Changes:**
-- Before first launch of any AppImage (check `launch_events` count = 0):
-  1. Show permission dialog:
-     - "MyApp will run with full access to your files and system"
-     - Icon + app name
-     - If `has_firejail()`: offer sandbox options
-       - "Run without restrictions" (default for now)
-       - "Run in Firejail sandbox (recommended)"
-     - "Don't show this again" checkbox (stored per-app in DB)
-  2. If user chooses Firejail: set `sandbox_mode = 'firejail'` in DB
-- New DB column: `first_run_prompted INTEGER NOT NULL DEFAULT 0`
-- Skip dialog if `first_run_prompted = 1`
-- Preferences: global toggle to disable first-run prompts
-
----
-
-### F20. Default App Selector
-
-**Complexity:** Medium (3 hrs)
-**Problem:** Can't set AppImage as default browser, mail client, etc.
-**Files:** `src/ui/detail_view.rs`, `src/core/integrator.rs`
-
-**Changes:**
-- Detect app capabilities from categories:
-  - `WebBrowser` -> can be default web browser
-  - `Email` -> can be default email client
-  - `FileManager` -> can be default file manager
-  - `TerminalEmulator` -> can be default terminal
-- Detail view overview tab: "Set as default" section (only shown for applicable categories)
-- Setting defaults:
-  - Browser: `xdg-settings set default-web-browser driftwood-{id}.desktop`
-  - Email: `xdg-mime default driftwood-{id}.desktop x-scheme-handler/mailto`
-  - File manager: `xdg-mime default driftwood-{id}.desktop inode/directory`
-- Before setting: query current default, store in `system_modifications` with `previous_value`
-- Uninstall: restore previous defaults via `undo_all_modifications()`
-- Requirements: app must be integrated first (needs .desktop file)
-
----
-
-### F21. Multi-User / System-Wide Install
-
-**Complexity:** Significant (4 hrs)
-**Problem:** Can't install for all users on a shared computer.
-**Files:** `src/core/integrator.rs`, `src/ui/detail_view.rs`, polkit policy
-
-**Changes:**
-- Reuses polkit policy from F15 (add new action `app.driftwood.Driftwood.system-install`)
-- "Install system-wide" option in detail view (requires app to be integrated first)
-- Flow:
-  1. `pkexec cp {appimage} /opt/driftwood-apps/{filename}`
-  2. `pkexec chmod 755 /opt/driftwood-apps/{filename}`
-  3. Generate system .desktop in `/usr/share/applications/driftwood-{id}.desktop`
-  4. `pkexec cp {desktop_file} /usr/share/applications/`
-  5. Copy icon to `/usr/share/icons/hicolor/` via pkexec
-  6. `pkexec update-desktop-database /usr/share/applications/`
-- Register all paths as `system_desktop`, `system_icon`, `system_binary` in system_modifications
-- Uninstall system-wide: `pkexec rm` for each tracked path
-- DB flag: `system_wide INTEGER NOT NULL DEFAULT 0`
-
----
-
-### F22. CLI Enhancements
-
-**Complexity:** Medium (3 hrs)
-**Problem:** Missing install-from-URL and update-all commands.
-**Files:** `src/cli.rs`
-
-**New commands:**
-- `driftwood install <url>` - Download from URL, validate, move to ~/Applications, set executable, register, optionally integrate
-- `driftwood update --all` - Check all apps, download and apply available updates
-- `driftwood autostart <path> --enable/--disable` - Toggle autostart for an AppImage
-- `driftwood purge` - Remove ALL system modifications for all managed apps (for Driftwood removal)
-- `driftwood verify <path>` - Check embedded signature or compare SHA256
-
----
-
-### F23. Portable Mode / USB Drive Support
-
-**Complexity:** Major (6-8 hrs)
-**Problem:** Can't manage AppImages on removable media.
-**Files:** New `src/core/portable.rs`, `src/ui/library_view.rs`, `src/window.rs`, `src/core/database.rs`
-
-**Changes:**
-- New GSettings key: `watch-removable-media` type b, default false
-- `portable.rs`:
-  ```rust
-  pub fn detect_removable_mounts() -> Vec<MountInfo>
-  pub fn scan_mount_for_appimages(mount: &MountInfo) -> Vec<DiscoveredAppImage>
-  pub fn is_path_on_removable(path: &Path) -> bool
-  ```
-- Detection: parse `/proc/mounts` for removable media (type vfat, exfat, ntfs on /media/ or /run/media/)
-- Alternative: use `gio::VolumeMonitor` to watch for mount/unmount events
-- DB changes:
-  - New column: `is_portable INTEGER DEFAULT 0`
-  - New column: `mount_point TEXT`
-- Library view: "Portable" filter/section showing apps on removable media
-- When drive unmounts: grey out those apps, mark as unavailable
-- When drive mounts: re-scan and refresh
-- Portable apps skip the "copy to ~/Applications" step - they stay on the drive
-- Integration: .desktop files use the full path (may break when unmounted - show warning)
-
----
-
-### F24. "Similar to..." Recommendations
-
-**Complexity:** Medium (3 hrs, depends on F26)
-**Problem:** No app discovery within the tool.
-**Files:** `src/ui/detail_view.rs`, `src/core/database.rs`
-
-**Changes:**
-- Requires catalog data from F26 (catalog_apps table populated)
-- New DB query: `find_similar_apps(categories: &[String], exclude_id: i64, limit: i32) -> Vec<CatalogApp>`
-- Matches on shared categories, weighted by specificity
-- Detail view overview tab: "You might also like" section at the bottom
-- Shows up to 5 catalog apps with icon, name, one-line description
-- Click opens catalog detail page (F26)
-- Falls back to nothing if catalog is empty
-
----
-
-### F25. AppImageHub In-App Catalog Browser
-
-**Complexity:** Major (8-12 hrs)
-**Problem:** No way to discover and install new AppImages from within the app.
-**Data source:** `https://appimage.github.io/feed.json` (~1500 apps)
-**Files:** New `src/ui/catalog_view.rs`, new `src/ui/catalog_detail.rs`, `src/core/database.rs`, `src/window.rs`
-
-**Architecture:**
-
-#### Data Layer
-- Fetch `feed.json` and parse into `catalog_apps` table (already exists in DB schema)
-- Store in `catalog_sources` as source record
-- Fields mapped from feed.json:
-  - `name` -> `name`
-  - `description` -> `description`
-  - `categories` -> `categories` (joined with ;)
-  - `authors[0].name` -> `author`
-  - `license` -> `license`
-  - `links` (type=GitHub) -> `repository_url`
-  - `links` (type=Download) -> `download_url`
-  - `icons[0]` -> `icon_url` (prefix with `https://appimage.github.io/database/`)
-  - `screenshots` -> `screenshots` (JSON array)
-- Refresh: on first open, then daily if enabled
-- New GSettings key: `catalog-last-refreshed` type s, default ''
-
-#### Catalog Browse View (NavigationPage)
-- Header: search bar + category filter chips
-- Categories from feed: AudioVideo, Development, Education, Game, Graphics, Network, Office, Science, System, Utility
-- Grid of catalog app cards (reuse app_card pattern):
-  - Icon (fetched from URL, cached locally)
-  - App name
-  - Short description (first line)
-  - Category badge
-- Pagination: load 50 at a time, "Load more" button
-- Search: filters by name and description (client-side, data is local)
-
-#### Catalog App Detail (NavigationPage pushed on click)
-- App icon (large)
-- Name, author, license
-- Full description
-- Screenshots carousel (if available)
-- "Install" button (suggested style)
-- Source link (opens GitHub/website in browser)
-
-#### Install Flow
-1. User clicks "Install"
-2. Resolve download URL:
-   - If `download_url` points to GitHub releases page: fetch latest release via GitHub API (`https://api.github.com/repos/{owner}/{repo}/releases/latest`), find .AppImage asset
-   - If direct link: use as-is
-3. Download with progress bar (reqwest or gio file download)
-4. Validate: check AppImage magic bytes
-5. Move to ~/Applications, set executable
-6. Register in DB with `source_url` set
-7. Run full analysis pipeline
-8. Optionally integrate (based on `auto-integrate` setting)
-9. Navigate to the app's detail view in library
-
-#### Navigation
-- Main sidebar/navigation: add "Catalog" entry alongside Dashboard and Library
-- Or: floating action button on library view "Browse catalog"

-## Implementation Order
-
-The features are numbered F1-F25 in order of complexity. Implement sequentially - some later features depend on earlier ones:
-
-- F25 (Catalog) depends on nothing but is largest
-- F24 (Similar to) depends on F25
-- F12 (Update All) depends on F11 (Background checks)
-- F13 (Full Uninstall) depends on system_modifications table (core architecture)
-- F20 (Default App) depends on F16 (MIME associations)
-
-**Critical path:** Core architecture (system_modifications) -> F1-F7 quick wins -> F8-F14 medium features -> F15-F22 significant features -> F23-F25 major features

-# Driftwood UI/UX Overhaul Design
-
-## Context
-
-Driftwood is a GTK4/libadwaita AppImage manager. The current UI is functional but visually plain - cards look like basic boxes, the list view resembles a settings page, and the detail view is a wall of ActionRows with no hierarchy. This design overhauls all three views plus adds a right-click context menu to make Driftwood feel like a first-class GNOME app.
-
-## Design Principles
-
-- Use libadwaita's built-in style classes wherever possible instead of custom CSS
-- Follow GNOME HIG spacing (6px grid, 12px padding baseline, 14px grid gaps)
-- Only show the most important information at each level (card -> list -> detail = progressive disclosure)
-- Actions belong in context menus and detail headers, not crammed into cards
-
----
-
-## 1. Card View (Grid)
-
-### Current State
-- 180px wide cards with 64px icons
-- All badges shown (Wayland, FUSE, Update, Integration)
-- Custom `.app-card` CSS duplicating libadwaita's `.card` behavior
-- FlowBox allows up to 6 columns (cards get too small)
-
-### New Design

-### Changes
-
-- **Card width: 200px** (from 180px) for better breathing room
-- **Icon size: 72px** (from 64px) with `.icon-dropshadow` class
-- **App name: `.title-3`** (from `.heading`) for more visual weight
-- **Version + size on one combined line** using `.caption .dimmed .numeric`
-- **Single badge only** - show the most important status using priority: Update > FUSE issue > Wayland issue. Integration is already shown via the icon corner emblem
-- **Replace custom `.app-card` CSS with libadwaita `.card` + `.activatable`** - native hover, active, dark mode, and contrast states for free
-- **FlowBox max 4 columns** (from 6) so cards stay readable
-- **14px row and column spacing** (matching GNOME Software)
-- **Right-click context menu** on each card (see Section 5)
-
-### Files Modified
-- `src/ui/app_card.rs` - card construction, badge logic, CSS classes
-- `data/resources/style.css` - remove `.app-card` rules, add new sizing
-- `src/ui/library_view.rs` - FlowBox max_children_per_line, context menu wiring

-## 2. List View
-
-### Current State
-- 40px icons, standard ActionRow
-- Subtitle mashes version + size + description into one hyphenated string
-- All badges shown in a suffix box
-- Standard ListBox (no `.rich-list`)

-
-### Changes
-
-- **Icon size: 48px** (from 40px) with `border-radius: 8px` and `overflow: hidden` for rounded clipping
-- **Subtitle structured as two lines:**
-  - Line 1: Description snippet or file path (dimmed)
-  - Line 2: Version + size (caption, dimmed, numeric)
-  - Use `subtitle-lines(2)` on ActionRow to allow the two-line subtitle
-- **`.rich-list` style class** on the ListBox for taller rows
-- **Single badge suffix** - same priority logic as cards
-- **Remove integration badge from suffix** - redundant with icon emblem
-- **Right-click context menu** - same menu as card view
-- **Navigate arrow stays** as rightmost suffix

-
-### Tab System
-- **`adw::ViewStack`** contains four pages
-- **`adw::ViewSwitcher`** with `.inline` style, placed between the banner and tab content (not in the header bar)
-- Header bar stays clean with just back button, app name title, Update button, Launch button
-
-### Tab 1: Overview (default)

-
----
-
-## 4. CSS & Visual Polish
-
-### Remove
-- `.app-card` and `.app-card:hover` and `.app-card:active` rules (replaced by libadwaita `.card`)
-- Dark mode `.app-card` overrides (handled by `.card` automatically)
-- High contrast `.app-card` overrides (handled by `.card` automatically)
-
-### Add
-```css
-/* Rounded icon clipping for list view */
-.icon-rounded {
-    border-radius: 8px;
-    overflow: hidden;
-}
-
-/* Detail banner gradient wash */
-.detail-banner {
-    padding: 18px 0;
-    background-image: linear-gradient(
-        to bottom,
-        alpha(@accent_bg_color, 0.08),
-        transparent
-    );
-    border-radius: 12px;
-    margin-bottom: 6px;
-}
-```
-
-### Keep (unchanged)
-- All status badge styling
-- Integration emblem styling
-- Letter-circle fallback icons
-- All WCAG AAA styles (focus indicators, high contrast, reduced motion, target sizes)
-- Compatibility warning banner
-- Quick action pill styling
-
-### Style Classes Used (libadwaita built-in)
-- `.card` + `.activatable` on FlowBoxChild card boxes
-- `.icon-dropshadow` on icons 48px+
-- `.rich-list` on list view ListBox
-- `.numeric` on version/size labels
-- `.title-3` on card app names
-- `.inline` on the detail ViewSwitcher
-- `.property` on key-value ActionRows where subtitle is the main content (path, SHA256)
-

-
-## 5. Right-Click Context Menu
-
-### Design
-A `GtkPopoverMenu` built from a `gio::Menu` model, attached to each FlowBoxChild (card) and ListBox row. Triggered by secondary click (button 3) or long-press on touch.
-
-```
-+---------------------------+
-|  Launch                   |
-+---------------------------+
-|  Check for Updates        |
-|  Scan for Vulnerabilities |
-+---------------------------+
-|  Integrate / Remove       |
-|  Open Containing Folder   |
-+---------------------------+
-|  Copy Path                |
-+---------------------------+
-```
-
-### Menu Items
-
-| Label | Action | Notes |
-|-------|--------|-------|
-| Launch | `app.launch-appimage(id)` | Launches the AppImage |
-| Check for Updates | `app.check-update(id)` | Triggers update check, shows toast with result |
-| Scan for Vulnerabilities | `app.scan-security(id)` | Triggers security scan, shows toast |
-| Integrate / Remove Integration | `app.toggle-integration(id)` | Label changes based on current state |
-| Open Containing Folder | `app.open-folder(id)` | Opens file manager to the directory |
-| Copy Path | `app.copy-path(id)` | Copies full path, shows toast |
-
-### Implementation Approach
-- Define actions at the window level with the record ID as parameter
-- Build a `gio::Menu` with sections (separators between groups)
-- Attach `GtkPopoverMenu` to each card/row
-- Wire `GtkGestureClick` for button 3 (right-click) and `GtkGestureLongPress` for touch
-- Update the "Integrate/Remove" label dynamically based on `record.integrated`
-
-### Files Modified
-- `src/window.rs` - define parameterized actions
-- `src/ui/library_view.rs` - create menu model, attach to cards and rows
-- `src/ui/app_card.rs` - gesture attachment on FlowBoxChild
-
----
-
-## 6. Files Modified Summary
-
-| File | Changes |
-|------|---------|
-| `src/ui/app_card.rs` | 72px icon, .title-3 name, single badge, .card class, gesture for context menu |
-| `src/ui/library_view.rs` | FlowBox max 4 cols, .rich-list on ListBox, list row restructure, context menu creation and attachment |
-| `src/ui/detail_view.rs` | 96px icon, ViewStack/ViewSwitcher tabs, redistribute rows into 4 tab pages, banner gradient |
-| `src/window.rs` | Parameterized actions for context menu (launch, update, scan, integrate, open-folder, copy-path) |
-| `data/resources/style.css` | Remove .app-card rules, add .icon-rounded, update .detail-banner with gradient, keep all WCAG styles |
-| `src/ui/widgets.rs` | Minor - ensure icon helper supports .icon-dropshadow |
-
-## Verification
-
-After implementation:
-1. `cargo build` - zero errors, zero warnings
-2. `cargo test` - all 128+ tests pass
-3. Visual verification of all three views in light + dark mode
-4. Right-click context menu works on cards and list rows
-5. Detail view tabs switch correctly, content is correctly distributed
-6. Keyboard navigation: Tab through cards, Enter to open, Escape to go back
-7. All WCAG AAA compliance preserved

-# WCAG 2.2 AAA Compliance Design for Driftwood
-
-## Context
-
-Driftwood is a GTK4/libadwaita AppImage manager. The app already uses semantic libadwaita widgets (ActionRow, PreferencesGroup, SwitchRow, NavigationView) and has partial accessibility support: ~11 accessible labels, status badges with text+color, keyboard shortcuts, and reduced-motion CSS. However, it falls short of full WCAG 2.2 AAA compliance.
-
-This design covers every change needed to achieve AAA compliance across all four WCAG principles: Perceivable, Operable, Understandable, and Robust.
-
-## Approach: Hybrid Helpers + Direct Properties
-
-Create centralized accessibility helper functions in `widgets.rs` for patterns that repeat (labeled buttons, described badges, live announcements), then add direct accessible properties for unique cases in each UI file. This keeps the code DRY while ensuring nothing is missed.
-
-## Scope
-
-**In scope:** All UI code in `src/ui/`, `src/window.rs`, and `data/resources/style.css`.
-**Out of scope:** CLI (`src/cli.rs`), core backend modules, build system.
-
----
-
-## 1. Perceivable (WCAG 1.x)
-
-### 1.1 Non-text Content (1.1.1 - Level A)
-
-**Current state:** 8 icon-only buttons, some with accessible labels, some without.
-
-**Changes needed:**
-- Add `update_property(&[AccessibleProperty::Label(...)])` to every icon-only button:
-  - `library_view.rs`: menu button, search button, grid button, list button
-  - `duplicate_dialog.rs`: delete button per row
-  - `widgets.rs`: copy button
-  - `preferences.rs`: remove directory button
-- Add accessible descriptions to integration emblem overlay in `app_card.rs`
-- Add accessible labels to all `gtk::Image` icons used as prefixes in rows (check icons in integration_dialog, category icons in cleanup_wizard)
-
-### 1.2 Time-based Media - N/A (no audio/video)
-
-### 1.3 Adaptable
-
-**1.3.1 Info and Relationships (A):**
-- Add `AccessibleRole::Group` to badge boxes in detail_view, library_view list rows, and app_card
-- Add `AccessibleProperty::Label` to ListBox containers in library_view (list view), preferences (directory list, cleanup wizard lists)
-- Add `AccessibleRelation::LabelledBy` connecting PreferencesGroup titles to their child row containers where applicable
-
-**1.3.6 Identify Purpose (AAA):**
-- Set `AccessibleRole::Banner` on the detail view banner
-- Set `AccessibleRole::Navigation` on the NavigationView wrapper
-- Set `AccessibleRole::Search` on the search bar
-- Set `AccessibleRole::Status` on status badges
-- Set `AccessibleRole::Main` on the main content area
-
-### 1.4 Distinguishable
-
-**1.4.6 Enhanced Contrast (AAA - 7:1 ratio):**
-- Add a `prefers-contrast: more` media query in `style.css` for high-contrast mode
-- In high-contrast mode: solid opaque borders on app cards (no alpha), bolder status badge colors, thicker focus rings (3px)
-- Verify that libadwaita theme variables meet 7:1 in both light and dark mode (they do - libadwaita's named colors are designed for WCAG AA, and the `prefers-contrast: more` variant handles AAA)
-
-**1.4.8 Visual Presentation (AAA):**
-- Text is already relative-sized (em units)
-- libadwaita handles line height and spacing according to system preferences
-- No changes needed beyond ensuring we do not override user-configured text spacing
-
-**1.4.11 Non-text Contrast (AA):**
-- Increase focus ring width to 3px (currently 2px) in high-contrast mode
-- Ensure status badge borders are visible at 3:1 ratio against their background
-
----
-
-## 2. Operable (WCAG 2.x)
-
-### 2.1 Keyboard Accessible
-
-**2.1.3 Keyboard No Exception (AAA):**
-- Verify all dashboard actionable rows are keyboard-activatable (they use `activatable: true` + `action_name`)
-- Verify cleanup wizard checkboxes are keyboard-toggleable via `activatable_widget`
-- Add keyboard shortcut Ctrl+Q for quit (already exists in GNOME via app.quit)
-- Ensure delete button in duplicate_dialog can be reached via Tab
-
-### 2.2 Enough Time
-
-**2.2.4 Interruptions (AAA):**
-- Toast notifications already have timeouts and can be dismissed
-- No other auto-updating content exists
-
-### 2.3 Seizures and Physical Reactions
-
-**2.3.3 Animation from Interactions (AAA):**
-- Expand `prefers-reduced-motion` CSS to cover ALL transitions:
-  - `navigation view` slide transitions (currently only covers `stack`)
-  - `adw::Dialog` presentation animations
-  - `flowboxchild` hover/active transitions
-  - Search bar reveal animation
-  - Spinner animations (already respected by adw::Spinner)
-
-### 2.4 Navigable
-
-**2.4.7 Focus Visible (AA) + 2.4.13 Focus Appearance (AAA):**
-- Add focus-visible styles for ALL focusable elements, not just app cards:
-  - `button:focus-visible` - 3px solid outline with accent color
-  - `row:focus-visible` - highlight with outline
-  - `switch:focus-visible`
-  - `checkbutton:focus-visible`
-  - `searchentry:focus-visible`
-  - `comborow:focus-visible`
-  - `spinrow:focus-visible`
-  - `expander:focus-visible`
-- Focus indicator must be at least 2px thick and have 3:1 contrast (AAA requires this)
-
-**2.4.8 Location (AAA):**
-- Update the window title dynamically to reflect current page: "Driftwood - Dashboard", "Driftwood - Security Report", "Driftwood - {App Name}"
-- This is already partially done via NavigationPage titles; ensure the window's actual title property updates
-
-**2.5.8 Target Size (AA):**
-- Audit all clickable targets for minimum 24x24px
-- The copy button, delete button (duplicate dialog), and remove directory button need `min-width: 24px; min-height: 24px` in CSS
-- Status badges in actionable rows are not click targets (the row is), so this is fine
-
----
-
-## 3. Understandable (WCAG 3.x)
-
-### 3.1 Readable
-
-**3.1.1 Language of Page (A):**
-- The GTK accessible layer reads the locale from the system. No explicit action needed for a native desktop app.
-
-**3.1.3 Unusual Words (AAA):**
-- Add `tooltip_text` explanations for technical terms displayed in the UI:
-  - "FUSE" -> tooltip: "Filesystem in Userspace - required for mounting AppImages"
-  - "XWayland" -> tooltip: "X11 compatibility layer for Wayland desktops"
-  - "AppImage Type 1/2" -> tooltip: "Type 1 uses ISO9660, Type 2 uses SquashFS"
-  - "CVE" -> tooltip: "Common Vulnerabilities and Exposures - security vulnerability identifier"
-  - "SHA256" -> tooltip: "Cryptographic hash for verifying file integrity"
-  - "Firejail" -> tooltip: "Linux application sandboxing tool"
-  - "zsync" -> tooltip: "Efficient delta-update download protocol"
-  - "fusermount" -> tooltip: "User-space filesystem mount utility"
-
-**3.1.4 Abbreviations (AAA):**
-- Expand "CVE" to "CVE (vulnerability)" on first use in security report
-- Expand "SHA256" to "SHA256 checksum" in detail view
-
-**3.1.5 Reading Level (AAA):**
-- Review all user-facing strings for plain language (most are already simple)
-- Replace "No update information embedded" with "This app cannot check for updates automatically"
-- Replace "AppImage does not contain update information" with "No automatic update support"
-
-### 3.2 Predictable - Already compliant (no unexpected changes)
-
-### 3.3 Input Assistance
-
-**3.3.5 Help (AAA):**
-- Add contextual descriptions to all PreferencesGroup widgets (already mostly done)
-- Add `description` text to any PreferencesGroup missing it
-
-**3.3.6 Error Prevention - All (AAA):**
-- Destructive actions already have confirmation (confirm-before-delete setting, alert dialogs)
-- Add confirmation to bulk "Remove All Suggested" in duplicate dialog (currently executes immediately)
-- Add confirmation to "Clean Selected" in cleanup wizard (currently executes immediately)
-
----
-
-## 4. Robust (WCAG 4.x)
-
-### 4.1.2 Name, Role, Value (A)
-
-**Accessible Names (all interactive elements):**
-Every button, toggle, switch, row, and input must have an accessible name. The full list of items needing labels:
-
-| Widget | File | Label to add |
-|--------|------|-------------|
-| Menu button | library_view.rs | "Main menu" |
-| Search toggle | library_view.rs | "Toggle search" |
-| Grid view toggle | library_view.rs | "Switch to grid view" |
-| List view toggle | library_view.rs | "Switch to list view" |
-| Copy button | widgets.rs | "Copy to clipboard" |
-| Delete button | duplicate_dialog.rs | "Delete this AppImage" |
-| Remove directory | preferences.rs | "Remove scan directory" |
-| Close button | cleanup_wizard.rs | "Close dialog" |
-| Clean Selected | cleanup_wizard.rs | "Clean selected items" |
-| Remove All Suggested | duplicate_dialog.rs | "Remove all suggested duplicates" |
-| Add Location | preferences.rs | "Add scan directory" |
-| Scan Now | library_view.rs | "Scan for AppImages" |
-| Preferences | library_view.rs | "Open preferences" |
-
-**Accessible Roles:**
-- `FlowBox` -> already has label
-- `ListBox` (list view) -> add `AccessibleProperty::Label("AppImage library list")`
-- `ListBox` (preferences directory list) -> add label "Scan directories"
-- `ListBox` (cleanup items) -> add label per category
-- `ListBox` (integration dialog identity) -> add label "Application details"
-- `ListBox` (integration dialog actions) -> add label "Integration actions"
-- Status badges -> add `AccessibleRole::Status` (or use `update_property` with `AccessibleProperty::Label`)
-
-**Accessible States:**
-- Switch rows -> GTK handles this automatically via `SwitchRow`
-- Scan button -> add `AccessibleState::Busy` while scanning is in progress
-- Security scan row -> add `AccessibleState::Busy` during scan
-- Analyze toolkit row -> add `AccessibleState::Busy` during analysis
-
-### 4.1.3 Status Messages (AA)
-
-**Live region announcements for async operations:**
-
-Create a helper function `announce(text: &str)` in widgets.rs that uses a hidden GTK Label with `AccessibleRole::Alert` to broadcast status changes to screen readers.
-
-Operations needing announcements:
-- Scan start ("Scanning for AppImages...")
-- Scan complete ("{n} AppImages found, {m} new")
-- Update check start/complete
-- Security scan start/complete
-- Cleanup analysis start/complete
-- Search results count change ("{n} results" or "No results")

-## Verification
-
-After implementation:
-1. `cargo build` - zero errors, zero warnings
-2. `cargo test` - all tests pass
-3. Run with Orca screen reader - verify every element is announced correctly
-4. Tab through entire app - verify all elements have visible focus indicators
-5. Set `GTK_THEME=Adwaita:dark` - verify dark mode focus/contrast
-6. Set high-contrast theme - verify enhanced contrast mode
-7. Set `GTK_DEBUG=interactive` - inspect accessible tree
-8. Keyboard-only navigation test through every screen
-9. Verify all targets meet 24x24px minimum
-10. Verify reduced-motion disables all animations
