Production code:
- pose_service.py: real uptime tracking (_start_time), real calibration
state machine (_calibration_in_progress, _calibration_id), proper
get_calibration_status() using elapsed time, uptime in health_check()
- health.py: _APP_START_TIME module constant for real uptime_seconds
- dependencies.py: remove TODO, document JWT config requirement clearly
ADR-017 status: Proposed → Accepted (all 7 integrations complete)
Test fixes (170 unit tests — 0 failures):
- Fix hardcoded /workspaces/wifi-densepose devcontainer paths in 4 files;
replaced with os.path relative to __file__
- test_csi_extractor_tdd/standalone: update ESP32 fixture to provide
correct 3×56 amplitude+phase values (was only 3 values)
- test_csi_standalone/tdd_complete: Atheros tests now expect
CSIExtractionError (implementation raises it correctly)
- test_router_interface_tdd: register module in sys.modules so
patch('src.hardware.router_interface...') resolves; fix
test_should_parse_csi_response to expect RouterConnectionError
- test_csi_processor: rewrite to use actual preprocess_csi_data /
extract_features API with proper CSIData fixtures; fix constructor
- test_phase_sanitizer: fix constructor (requires config), rename
sanitize() → sanitize_phase(), fix empty-data fixture (use 2D array),
fix phase data to stay within [-π, π] validation range
Proof bundle: PASS — SHA-256 hash matches, no random patterns in prod code
