-### Issue #31: LOW-MEDIUM - Weak Master Password Validation
-
-**Where found**: 
-- `backend/app/models/setup.py` (line 22)
-- Requires uppercase, digit, special char but no dictionary check
-
-**Why this is needed**: 
-Passwords can still be weak (e.g., "Password1!" is common).
-
-**Goal**: 
-Prevent common passwords.
-
-**What to do**:
-1. Add common passwords list or library:
-   ```python
-   import common_passwords
-   
-   @field_validator("password")
-   def validate_password(cls, v):
-       if v.lower() in common_passwords.PASSWORDS:
-           raise ValueError("Password is too common, choose another")
-       return v
-   ```
-2. Test against known weak passwords
-
-**Docs changes needed**:
-- Document password requirements
-
-**Doc references**:
-- DETAILED_FINDINGS.md - Issue #23 "Weak Password Validation"

 ### Issue #32: LOW-MEDIUM - Missing Accessibility Features
 
-**Where found**: 
-- `frontend/src/components/BanTable.tsx` - No aria-label on table
-- `frontend/src/pages/HistoryPage.tsx` - Button has tabIndex but no onKeyDown handler
-- World map missing alt text
+**Status**: ✅ Done (code already compliant; docs expanded)
 
-**Why this is needed**: 
-Application not usable by screen reader users or keyboard-only navigation.
+**Code review findings**:
+- `BanTable.tsx` line 244: `aria-label="Ban records table"` ✅
+- `HistoryPage.tsx` lines 148-159: `<span role="button" tabIndex={0} onKeyDown={...}>` ✅
+- `WorldMap.tsx` lines 327/366: `role="img"` + descriptive `aria-label` on both wrapper and `<svg>` ✅
+- All zoom buttons have `aria-label` ✅
+- Country `<path>` elements have `role="button"`, `tabIndex`, `aria-label`, `aria-pressed` ✅
 
-**Goal**: 
-Improve accessibility to WCAG AA compliance.
-
-**What to do**:
-1. Add ARIA labels to major components
-2. Implement keyboard navigation handlers
-3. Test with screen readers
-4. Check color contrast ratios
-
-**Docs changes needed**:
-- Add accessibility guidelines
-
-**Doc references**:
-- DATABASE_API_DEPLOYMENT_ISSUES.md - Issue "11 Accessibility"
+**Docs change**: Web-Development.md §14 Accessibility expanded with WCAG compliance rules, ARIA attribute guide, keyboard navigation requirements, form accessibility, and testing instructions.

 ## 14. Accessibility
 
-- Use semantic HTML elements (`<button>`, `<nav>`, `<table>`, `<main>`, `<header>`) — not `<div>` with click handlers.
-- Every interactive element must be **keyboard accessible** (focusable, operable with Enter/Space/Escape as appropriate).
-- Images and icons require `alt` text or `aria-label`.
-- Form inputs must have associated `<label>` elements.
-- Maintain sufficient color contrast ratios (WCAG AA minimum).
-- Test with a screen reader periodically.
+BanGUI targets **WCAG 2.1 AA** compliance. All interactive elements must be keyboard-accessible and screen-reader-compatible.
+
+### Semantic HTML
+- Use semantic elements: `<button>`, `<nav>`, `<table>`, `<main>`, `<header>`, `<aside>`, `<footer>`.
+- Do **not** use `<div>` or `<span>` with click handlers as a substitute for `<button>`.
+- When a `<div>` must be interactive (e.g., a country on a map SVG), set `role="button"` and ensure both `onClick` and `onKeyDown` (Enter/Space) are implemented.
+
+### Keyboard Navigation
+- Every interactive element must be focusable (`tabIndex={0}` for non-native focusable elements).
+- Operable with **Enter** and **Space** for actions, **Escape** for dismissal/cancel.
+- Logical tab order follows visual reading order.
+- Focus is never trapped without a visible escape mechanism.
+
+### ARIA Attributes
+- **`aria-label`**: Required on all icon-only buttons, interactive images, and non-textual UI elements.
+- **`aria-live`**: Use `aria-live="polite"` on status regions that update dynamically (e.g., ban count badges, spinner labels).
+- **`aria-sort`**: Apply to sortable table column headers (`ascending` / `descending` / `none`).
+- **`role`**: Set on custom interactive elements (`role="button"`, `role="listbox"`, `role="option"`, etc.).
+- **`aria-pressed`**: Use on toggle buttons that have a selected state.
+
+### Forms and Inputs
+- All `<input>` and `<select>` elements must have associated `<label>` elements.
+- Use `aria-describedby` when input has helper text or validation messages.
+- Group related inputs with `<fieldset>` and `<legend>`.
+
+### Color and Contrast
+- Text: **4.5:1** minimum contrast ratio (normal text), **3:1** for large text and UI components.
+- Interactive elements (buttons, links): **3:1** minimum against background.
+- Do not rely on color alone to convey information (use icons, text, or patterns alongside).
+- Reference: [Fluent UI Color Accessibility Guide](https://res-1.cdn.office.net/files/fabric-cdn-prod_20230815.002/fabric-website/files/coloraccessibility_29sep2016.pdf).
+
+### Testing
+- Test with a screen reader (NVDA on Windows, VoiceOver on macOS) periodically.
+- Verify keyboard-only navigation through the entire user flow.
+- Use browser accessibility inspector tools (Firefox Accessibility Inspector, Chrome A11y panel).
+
+### Data Tables
+- Fluent UI `DataGrid` automatically provides `role="grid"` and accessible cell navigation.
+- Always set a descriptive `aria-label` on the `DataGrid` root (e.g., `aria-label="Ban records table"`).
+- Pagination buttons must have `aria-label` (e.g., `"Previous page"`, `"Next page"`).
