-# Sleep Timetable Bug Fixes
-
-## Identified Issues
-1. **Pre-selection**: Component doesn't always pre-select the latest date across all tiers.
-2. **Grid Layout (Medium Tier)**: Grid columns are hardcoded to 3, causing breakage when fewer than 3 days are displayed at the end of a range.
-3. **Selector Information**: Tabs only show weekday names, making it hard to distinguish dates.
-
-## Implementation Plan
-
-### 1. Fix Pre-selection
-- Add a `useEffect` to set `selectedDayIndex` to the last index of the `days` array whenever the `days` list is initialized or updated. This ensures "today" (the latest date) is selected by default.
-
-### 2. Fix Grid Alignment
-- Refactor the `gridTemplateColumns` logic for both the header and time grid.
-- Instead of hardcoding tiers (e.g., `repeat(3, 1fr)`), use the actual number of days in the current view: `4rem repeat(${visibleDays.length}, 1fr)`. This allows the grid to gracefully handle 1, 2, or 3 columns.
-
-### 3. Enhance Selector Labels
-- Implement a `formatDayLabel` helper that combines the short weekday name and the day of the month (e.g., "FRI 24").
-- Update `tabGroups` generation for both 'medium' (range) and 'small' (single day) tiers to use this descriptive label.
-
-### 4. UI Compactness
-- Adjust spacing (margins/paddings) in the mobile/medium view to reduce overall component height and keep selectors closer to the grid.

+# Things I need to tell my AI to do
+
+- [ ] Check so that all tests actually make sense, maybe some are now obsolete, and some are missing
+- [ ] Add a test coverage metric to both frontend and backend so that we can check how much of the code is tested. I would like >=90%
+- [ ] Go over Claude's slop-cleanup-stuff
+- [ ] Update the "Sleep Sessions" by adding a fake pagination view in the frontend so that I don't have to scroll so much. Instead, I want to simply click "next" and "previous" (with like numbers in between like a google search)
