Detailed Bug Report: Running Workout Incline Parsing Issue & CORE Sensor Garmin Sync Failure

[cagnulein]

Summary

Bug fixes

• Incline parsing (ZWO/XML): fixed incorrect ×100 multiplication applied to incline values already expressed as percentages. The new normalizeIncline heuristic (threshold ≤0.40) correctly handles both fraction-encoded files (e.g. Incline="0.02" = 2%) and percent-encoded files (e.g. Incline="2.0" = 2%), covering realistic treadmill inclines up to 40%.
• Garmin workout download: fixed crash/miss when a scheduled workout (itemType="workout") had no workoutUuid — these now use the schedule id field instead.
• Garmin multi-workout prompt: fixed race condition where downloading multiple workouts in the same session would overwrite the prompt — workouts are now queued and shown one at a time.

New features

• CORE sensor Garmin sync: FIT files now include CORE body temperature data with the correct CORE app UUID (6957fe68-83fe-4ed6-8613-413f70624bb5) and full field set (core/skin temperature, heat strain index, CIQ fields, lap and session summaries) recognized by Garmin Connect.
• Garmin workout filename includes sport suffix: downloaded workouts are saved as date - name_Run.xml / _Ride.xml etc., preventing same-day run/ride name collisions.
• Garmin download on startup toggle: new setting garmin_download_workouts_on_start (default: enabled) to control whether QZ auto-fetches today's Garmin workout at launch.
• Multiple Garmin workouts per day: the fallback calendar lookup now downloads all workouts tied to the nearest scheduled day instead of only the first one found.
• XML files with ZWO content: .xml files whose root element is <workout_file> or <Workout> are now parsed by the Zwift workout engine, not the QZ XML parser. Detection is done by reading the root element, no extension rename needed.
• <Step> element support in ZWO/XML: new direct-speed step format (<Step Duration="120" Speed="6.0" Incline="2"/>) is now parsed for running workouts.
• SteadyState with direct Speed: when a SteadyState block carries a Speed attribute and the sport is running, speed is applied directly in km/h instead of being converted from power/pace.
• Clipboard workout detection: new opt-in setting trainprogram_clipboard_workout_enabled (default: disabled). When active, QZ polls the clipboard every 5 seconds; if a valid ZWO or QZ XML workout is detected, the user is prompted to open it. At workout end, QZ asks whether to delete the temporary file.
• Paste from clipboard in Workout Editor: new "Paste from Clipboard" button in the embedded workout editor allows pasting a QZ XML workout directly from the clipboard.
• Delete workout from UI: the Training Programs list now includes a Delete button with confirmation dialog. Deletion is restricted to files inside the training/ folder (path traversal protected).
• Recursive workout listing: the Training Programs list now shows workouts from all subfolders (e.g. run/Garmin/, ride/Garmin/) with relative path display, not only the top-level training/ directory.

Tests

• Added ZwiftWorkoutTestSuite: covers percent/fraction incline parsing, negative incline, direct Speed attribute, <Step> format, and .xml extension auto-detection.
• Added Garmin filename tests: sport suffix appended correctly, unsafe characters sanitized.
