## Task Commits
|
|
|
|
Each task was committed atomically:
|
|
|
|
1. **Task 1: Create filterEntries utility function** - `8f544a9` (feat)

|
## Files Created/Modified
|
|
- `src/lib/utils/filterEntries.ts` - Filters entries by SearchFilters criteria
|
|
- `src/lib/utils/highlightText.ts` - Wraps matching text in mark tags with XSS protection
|
|
|
|
## Decisions Made
|
|
- Case-insensitive matching for both text search and tag filtering (per 04-01 decision)
|
|
- AND logic for multiple tag filters (entry must have ALL selected tags)
|
|
- HTML escaping before regex replacement to prevent XSS
|
|
- Bold styling (font-bold) without background (bg-transparent) per CONTEXT.md
|
|
|

|
|
- SearchFilters type from 05-01 used correctly
|
|
- Both functions are pure and testable
