## QA PASSED See QA report document: 7053d758-27f5-4acb-82a8-a35290b512ef **All 13 hypotheses tested. No issues found.** Verified: - /health and /endpoints bypass authentication - POST / returns 401 without auth when API key configured - Bearer token and X-Api-Key headers both work - Invalid keys return 401 with appropriate error messages - Backwards compatibility confirmed (open access when no API key) - HTTPS via reader.roboalch.com works correctly Fix verified working. Marking as done.

## Implementation Complete ### Changes Made **1. Added API key authentication to reader-server** - File: src/reader_server/server.py - Added api_key field to Settings class (line 47) - Added AUTH_BYPASS_PATHS constant with /health and /endpoints (line 297) - Added HTTP middleware api_key_auth_middleware (lines 300-346) that: - Bypasses auth for /health and /endpoints endpoints - Allows open access when no API key is configured (backwards compatible) - Validates API key via Authorization: Bearer <key> header - Validates API key via X-Api-Key header (takes precedence) - Returns 401 with descriptive error for missing/invalid keys **2. Added comprehensive unit tests** - File: tests/test_unit.py - Added 14 new tests in TestApiKeyAuthentication class testing all auth scenarios **3. Updated README with authentication docs** - File: README.md - Added API key feature to features list - Added READER_API_KEY to configuration table - Added new Authentication section with examples **4. Updated docker-compose for deployment** - File: ~/setup/reader-server/docker-compose.yml - Added READER_API_KEY environment variable (defaults to empty for backwards compatibility) ### Test Results All 66 unit tests pass. Linting passes with no errors.
