Summary of ChangesHello @CodeWithCJ, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed! This pull request significantly enhances the Fitbit data synchronization capabilities by integrating new data types such as Cardio Fitness (VO2 Max) and Core Temperature. It also optimizes existing activity processing, ensuring more accurate and comprehensive recording of user steps and exercise data, while improving the robustness of exercise entry management within the system. The changes aim to provide users with a richer and more reliable fitness tracking experience. Highlights

Code Review
The pull request introduces several improvements to the Fitbit data sync process, including support for new metrics like VO2 Max and Core Temperature, and a fallback mechanism for step data. However, there are a few concerns regarding the efficiency of database operations during the sync and a potential bug where multiple Fitbit activities of the same type on the same day might overwrite each other. Additionally, the hardcoded exclusion of "Walk" activities should be reviewed as it may lead to data loss for users who track walks as exercises.

The current logic for skipDuplicateCheck does not include Fitbit. This means that if a user has multiple activities of the same type (e.g., two separate runs) on the same day, the second one will overwrite the first one because the uniqueness check at line 347 only considers exercise_id and entry_date. Since Fitbit activities now include a unique source_id (the logId), Fitbit should be added to this list to allow multiple entries, or the uniqueness check should be updated to use source_id for better deduplication.

Using substring(0, 10) on the raw activity.startTime is less robust than using the normalized ISO string from the parseFitbitTime helper. Additionally, the startIso variable is currently defined but unused in the rest of the loop, making it dead code. Using it to derive entryDate solves both issues.

| const startIso = parseFitbitTime(activity.startTime, timezoneOffset); | |
| const startIso = parseFitbitTime(activity.startTime, timezoneOffset); | |
| const entryDate = startIso.split("T")[0]; |

Hardcoding the exclusion of "Walk" activities may lead to data loss for users who track walks as exercises (e.g., for GPS maps, pace, or heart rate details). While these are also counted as steps, the exercise entry itself provides valuable context and historical data. Consider making this behavior configurable or only skipping walks that don't meet a certain threshold of duration or intensity.

Performing a database query (getCheckInMeasurementsByDate) inside a loop over stepsPerDay is inefficient, especially during a multi-day sync. It is recommended to fetch all measurements for the relevant date range in a single query using measurementRepository.getCheckInMeasurementsByDateRange before the loop and then perform the comparison in-memory.
- migrated the whole /pages/diary directory to tanstack query - fixed unnecessary use of window listeners from CodeWithCJ#690 - fixes bug preventing to upload images - splitting components in seperate files - decouple logic from ui by moving the functions to utils

Summary
This PR addresses several data accuracy issues and adds support for new health metrics in the Fitbit integration. The primary goal was to ensure that step data is reliable even when specific API summaries are missing and to fix a logic bug that caused activities to "shift" calendar days.
Key Changes
🛠 Bug Fixes & Accuracy
Date-Shifting Fix: Modified
processFitbitActivities
to extract the entry date directly from the local startTime string. This prevents late-night activities (e.g., an 8 PM walk) from being shifted to the next day due to UTC conversion.
Step Fallback Logic: Implemented a mechanism that sums steps from all individual activities (Walks, Runs, etc.) for a given day. If the official Fitbit daily summary is missing or reports a lower number, the system automatically uses the activity sum to update the daily total.
Respiratory Rate Mapping: Fixed a bug where respiratory rate data was missed; the processor now correctly checks both the standard and fullSleepSummary paths in the Fitbit response.
✨ New Features & Improvements
Exercise Diary Filtering: Activities named "Walk" are now filtered out from being created as separate exercise cards. This prevents diary clutter while ensuring their steps still contribute to the daily goal via the fallback logic.
New Metrics Support: Added synchronization for:
Cardio Fitness Score (VO2 Max)
Core Temperature
Duplicate Prevention: Integrated source_id checks (using Fitbit's logId) to prevent duplicate exercise entries during repeated syncs.
📝 Technical Improvements
Refined the use of
upsertStepData
to ensure the "best available truth" (official total vs. activity sum) is persisted in the check_in_measurements table.
Improved debug logging across the data processor for easier troubleshooting of sync discrepancies.
