 - **Frontend JS Slop**: NEVER create `.js` or `.jsx` files for the frontend. Use only TypeScript (`.ts`, `.tsx`). Write clean, type-safe code.
 - **Assumption Error**: NEVER assume the content of ANY files. ALWAYS read the target file to confirm its structure and implementation before modifying or referencing it.
 
+## MANDATORY EXECUTION PROTOCOLS (INJECTABLE)
+
+The following protocols must be strictly adhered to upon injection:
+- **Read Before Edit**: ALWAYS read the entire target file before performing any `edit` operation.
+- **Post-Edit Verification**: Immediately after an edit, verify that no lines have been duplicated.
+- **Stability Check**: Following any code change, run both backend and frontend services AND the full test suite to ensure system stability.

+- [x] Fix race condition of gitea workflows
+
+If both workflows run at the same time, a race condition occurs:
+1. Collision: Both workflows will query the latest tag (e.g., v1.0.5) and calculate the same next version (v1.0.6).
+2. The Winner: The first workflow to finish its push will successfully create the v1.0.6 tag on the remote.
+3. The Loser: The second workflow will attempt to push v1.0.6, but the remote will reject it because that tag already exists, causing the workflow to fail.
+This happens because both workflows share the same global tag namespace (v1.0.x). To fix this, you should differentiate them by using unique prefixes, such as backend-v1.0.x and frontend-v1.0.x.
+
+--> Invalid. the containers are named differently.

-# Plan: Fix Timezone Handling in Wakeup Times Module
-
-## Problem Description
-The "Wakeup Times" chart (in `frontend/src/components/stats/WakeupPlot.tsx`) displays wakeup times incorrectly due to a timezone mismatch. 
-- **Observation**: If a baby wakes up at `05:55` local time (e.g., in UTC+2), the chart shows `03:55`.
-- **Cause**: The backend stores times in UTC. The frontend currently receives minutes relative to UTC midnight and renders them directly using `formatMinutesAfter` without applying the client's local timezone offset.
-
-## Investigation Steps
-1. **Backend Verification**: 
-   - Examine `backend/app/routers/stats.py` (or equivalent) and the CRUD logic to confirm that `wakeup_minutes` is calculated based on UTC midnight.
-   - Verify how the backend handles the `wakeup_ref` and `bedtime_ref` parameters.
-2. **Frontend Logic Audit**: 
-   - Trace the data flow from `fetchWakeSleepTimes` -> `useStats` -> `WakeupPlot.tsx`.
-   - Confirm that `wakeup_minutes` is indeed a raw offset from UTC midnight.
-
-## Implementation Plan
-1. **Calculate Local Offset**: Use `new Date().getTimezoneOffset()` in the frontend to determine the difference between UTC and local time.
-2. **Adjust Minutes**: 
-   - In `WakeupPlot.tsx`, modify the mapping logic to adjust `day.wakeup_minutes` by the local timezone offset before it is passed to `formatMinutesAfter`.
-   - Formula: `local_minutes = utc_minutes - (timezone_offset_in_minutes)`. 
-     *(Note: `getTimezoneOffset()` returns minutes positive for west of UTC, negative for east, so subtraction is correct to add offset to UTC).*
-3. **Refactor Utilities (if needed)**: If the logic is used elsewhere, consider moving timezone-aware formatting to `frontend/src/utils/time.ts`.
-
-## Verification Plan
-1. **Manual Verification**: 
-   - Mock a response from the backend with a known UTC time.
-   - Check if the rendered string matches the expected local time.
-2. **Automated Testing**: 
-   - Add/update a test case in `frontend/tests/e2e/stats.spec.ts` (or a unit test in `frontend/tests/`) that simulates different timezone offsets to ensure the display is correct.
-3. **Regression Check**: 
-   - Ensure `BedtimePlot.tsx` and other time-related components are not negatively impacted by changes to shared utilities.
