Phase 5 Plan 02: Filtering & Highlighting Utilities Summary

Pure filter and highlight utilities with case-insensitive search, AND-logic tag filtering, and XSS-safe text highlighting

Performance

• Duration: 1 min
• Started: 2026-01-31T16:11:19Z
• Completed: 2026-01-31T16:12:57Z
• Tasks: 2
• Files modified: 2

Accomplishments

• filterEntries utility filtering by query, tags, type, and date range
• highlightText utility with XSS protection via HTML escaping
• Case-insensitive text search with 2-character minimum trigger
• AND logic for tag filtering (entry must have ALL selected tags)

Task Commits

Each task was committed atomically:

1. Task 1: Create filterEntries utility function - 8f544a9 (feat)
2. Task 2: Create highlightText utility function - 6dbe660 (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

Deviations from Plan

None - plan executed exactly as written.

Issues Encountered

None

User Setup Required

None - no external service configuration required.

Next Phase Readiness

• Filter and highlight utilities ready for integration in 05-03
• SearchFilters type from 05-01 used correctly
• Both functions are pure and testable
