### Neo — Admin-Only /about Endpoint for FUTURE.md and DEVELOPMENT_LOG.md
**Status:** ✅ COMPLETED
**Task ID:** admin-about-endpoint-001
**Priority:** MEDIUM
**Started:** 2026-05-09 15:25 CDT
**Completed:** 2026-05-09 15:30 CDT
**Objective:**
Create a backend endpoint that serves FUTURE.md and DEVELOPMENT_LOG.md content to admin users only.
**Work Completed:**
- [x] Created new route file `routes/aboutAdmin.js` with file reading logic
- [x] Implemented admin-only access using existing `requireAuth` and `requireAdmin` middleware
- [x] Added proper error handling for file read operations

- [x] Used `fs.readFileSync` with UTF-8 encoding for file reading
- [x] Added path resolution relative to the routes file
**Files Modified:**
- `routes/aboutAdmin.js` — New file containing the admin-only endpoint implementation
- `server.js` — Added route registration for `/api/about-admin`
**Deliverables:**
- Admins can now access FUTURE.md and DEVELOPMENT_LOG.md content via a secure API endpoint
- Endpoint returns structured JSON with both file contents
- Non-admin users get 403 Forbidden

## 🔴 CRITICAL: Non-Admin Test User Environment Variable for Role-Based Testing
**Priority:** CRITICAL
**Status:** PENDING
**Added:** 2026-05-09 by _null
**Description:**
Need an environment variable to create a non-admin test user. Currently `INIT_TEST_USER` / `INIT_TEST_PASS` creates a user **with admin privileges** — we need a separate non-admin user to verify role-based access controls (403 on admin-only endpoints like `/api/about-admin`).
**Rationale:**
- `INIT_ADMIN_USER` / `INIT_ADMIN_PASS` creates the admin user
- `INIT_TEST_USER` / `INIT_TEST_PASS` also creates an admin-tagged user (used for testing admin flows)
- We have NO way to create a non-admin user for testing that 403 works on admin-only endpoints
- Cannot test that the `/admin/about` page is inaccessible to regular users
- Essential for proper security testing of role-based features
**Implementation Notes:**
- Add `INIT_REGULAR_USER` and `INIT_REGULAR_PASS` environment variables (suggested defaults: `regularuser` / `regularpass123`)
- Create the regular (non-admin) user in `seedDefaults()` or similar init function
- User must have `role = 'user'` (NOT admin)
- Only create if env vars are set (optional, for testing environments)
- Update Docker test command in MEMORY.md to include these env vars
- Update Engineering_Reference_Manual.md with new env vars
- **Do NOT repurpose INIT_TEST_USER — that's already an admin user**

### Security (2026-05-09)
- **Admin-only `/admin/about` route guard** — React `RequireAuth` middleware protects `/admin/about` route
- **Rate limiting on `/api/about-admin`** — `adminActionLimiter` (30 req/15min per IP) applied to prevent brute-force attempts
- **XSS prevention** — `rehype-sanitize` added to ReactMarkdown component in AboutPage.jsx
- **Content redaction** — `routes/aboutAdmin.js` sanitizes paths, redacts internal IPs, passwords, API keys
- **Error sanitization** — Error messages exclude paths to prevent path disclosure
- **Non-admin test user** — Added `INIT_REGULAR_USER` and `INIT_REGULAR_PASS` env vars for role-based testing

## Version Bump Convention
### Version Format
Bill Tracker follows [Semantic Versioning](https://semver.org/): `MAJOR.MINOR.PATCH`
### Version Bump Rules
| Bump Type | When to Bump | Examples |
|-----------|-------------|----------|
| **Patch (x.y.Z)** | Bug fixes, security patches, hotfixes | v0.19.0 → v0.19.1 |
| **Minor (x.Y.z)** | New features, new endpoints, new environment variables | v0.19.0 → v0.20.0 |
| **Major (X.y.z)** | Breaking changes, schema changes, API changes | v0.19.0 → v1.0.0 |
### Version Updates
| Change | Version Bump | HISTORY.md Entry |
|--------|--------------|------------------|
| Security fix in `routes/*.js` | Patch | Under current minor version |
| New API endpoint | Minor | Under current minor version |
| New env variable (`INIT_REGULAR_USER`) | Minor | Under current minor version |
| Breaking change to frontend | Major | Under new major version |
| Database schema change | Major | Under new major version |
### Current Version
- **Current Version**: v0.19.0
- **Package.json**: `version: "0.19.0"`
- **HISTORY.md**: Top entry matches current version
### Version Sync
The version in `package.json` and top of `HISTORY.md` must always be in sync. After any change that qualifies for a bump, update both files and document in HISTORY.md under the appropriate version section.
