Implemented three new API endpoints for knowledge graph visualization: 1. GET /api/knowledge/graph - Full knowledge graph - Returns all entries and links with optional filtering - Supports filtering by tags, status, and node count limit - Includes orphan detection (entries with no links) 2. GET /api/knowledge/graph/stats - Graph statistics - Total entries and links counts - Orphan entries detection - Average links per entry - Top 10 most connected entries - Tag distribution across entries 3. GET /api/knowledge/graph/:slug - Entry-centered subgraph - Returns graph centered on specific entry - Supports depth parameter (1-5) for traversal distance - Includes all connected nodes up to specified depth New Files: - apps/api/src/knowledge/graph.controller.ts - apps/api/src/knowledge/graph.controller.spec.ts Modified Files: - apps/api/src/knowledge/dto/graph-query.dto.ts (added GraphFilterDto) - apps/api/src/knowledge/entities/graph.entity.ts (extended with new types) - apps/api/src/knowledge/services/graph.service.ts (added new methods) - apps/api/src/knowledge/services/graph.service.spec.ts (added tests) - apps/api/src/knowledge/knowledge.module.ts (registered controller) - apps/api/src/knowledge/dto/index.ts (exported new DTOs) - docs/scratchpads/71-graph-data-api.md (implementation notes) Test Coverage: 21 tests (all passing) - 14 service tests including orphan detection, filtering, statistics - 7 controller tests for all three endpoints Follows TDD principles with tests written before implementation. All code quality gates passed (lint, typecheck, tests). Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>

Issue #67: [KNOW-015] Search UI
Objective
Build a comprehensive search interface in the Next.js web UI with search-as-you-type, filters, keyboard shortcuts, and highlighted snippets.
Approach
- Review existing web UI structure and components
- Design component architecture for search functionality
- Implement TDD workflow (RED-GREEN-REFACTOR):
- Write tests for search input component
- Implement search input with Cmd+K shortcut
- Write tests for search results page
- Implement search results with highlighting
- Write tests for filter sidebar
- Implement filter functionality
- Add no results state
- Ensure all tests pass and coverage meets 85% minimum
- Run quality gates and code review
- Commit and close issue
Component Architecture
SearchInput- Header search component with Cmd+K shortcutSearchResults- Main results page/componentSearchResultItem- Individual result with highlighted snippetsSearchFilters- Sidebar for tag and status filteringNoResults- Empty state component
Progress
- Create scratchpad
- Review existing web UI structure
- Write tests for SearchInput component
- Implement SearchInput with keyboard shortcut
- Write tests for SearchResults page
- Implement SearchResults page
- Write tests for SearchResultItem with highlighting
- Implement result item with snippet highlighting
- Write tests for SearchFilters
- Implement filter sidebar
- Write tests for NoResults state
- Implement no results state
- Add debounced search-as-you-type
- Create search page at /knowledge/search
- Add search button to Navigation header
- Fix Input component to support forwardRef
- All tests passing (100% coverage)
- Typecheck passing
- Lint passing
- Commit changes (
3cb6eb7) - Close issue #67
Summary
Successfully implemented comprehensive search UI for knowledge base with:
- Full TDD approach (tests written first)
- 100% code coverage on main components
- All acceptance criteria met
- PDA-friendly design principles followed
- Quality gates passed (typecheck, lint, tests)
Components created:
- SearchInput (debounced, Cmd+K shortcut)
- SearchFilters (tags and status filtering)
- SearchResults (main results view with highlighting)
- Search page at /knowledge/search
- Updated Navigation with search button
All files pass pre-commit hooks and quality checks.
Testing Strategy
- Unit tests for all components
- Test keyboard shortcuts (Cmd+K, Escape)
- Test debouncing behavior
- Test filter interactions
- Test safe HTML rendering for highlights
- Test no results state
- Aim for 85%+ coverage
Notes
- Use Shadcn/ui components (Input, Card, Badge, etc.)
- Follow PDA-friendly language (no "URGENT", "MUST", etc.)
- Use visual indicators: 🟢 Active, 🔵 Scheduled, ⏸️ Paused, 💤 Dormant, ⚪ Not started
- Safely render HTML snippets from API (use dangerouslySetInnerHTML with sanitization or a library)
- Debounce search input to avoid excessive API calls
- Cmd+K should open search modal/focus search input
- Escape should close search modal if open
