Phase 18 Plan 02: PhaseAccordion, TaskRow & DependencyIndicator Summary

Three interconnected components for the initiative detail hierarchy view: expandable phase containers, task rows with tree connectors, and dependency annotations

Performance

• Duration: 4 min
• Started: 2026-02-04
• Completed: 2026-02-04
• Tasks: 3
• Files modified: 3

Accomplishments

• DependencyIndicator: pure presentational component rendering ^ blocked by: name1, name2 in amber text, returns null when empty
• TaskRow: task row with Unicode tree connectors (├── / └──), StatusBadge, inline agent name in blue, DependencyIndicator for blocked tasks, clickable with hover feedback
• PhaseAccordion: expandable/collapsible phase container with ChevronDown/ChevronRight toggle, phase number + name header, task count (completed/total), StatusBadge, phase-level DependencyIndicator, and TaskRow list when expanded
• All components are presentational — data assembly handled by parent page

Task Commits

Each task was committed atomically:

1. Task 1: Create DependencyIndicator component - a00b7b5 (feat)
2. Task 2: Create TaskRow component - 4becfe8 (feat)
3. Task 3: Create PhaseAccordion component - 92d4d36 (feat)

Files Created/Modified

• packages/web/src/components/DependencyIndicator.tsx - Blocked-by annotation with ^ prefix in amber text
• packages/web/src/components/TaskRow.tsx - Task row with tree connectors, status badge, agent name, dependency indicator
• packages/web/src/components/PhaseAccordion.tsx - Expandable phase container with chevron toggle, task count, status, task list

Decisions Made

• 18-02: SerializedTask type defined in TaskRow (same Date-to-string serialization pattern as SerializedInitiative)
• 18-02: Phase hierarchy flattened — Plan layer hidden per decision 15-02, tasks rendered directly under phase
• 18-02: Underscore prefix for unused type prop in DependencyIndicator (_type) to satisfy noUnusedParameters

Deviations from Plan

None - plan executed exactly as written.

Issues Encountered

None

User Setup Required

None - no external service configuration required.

Next Phase Readiness

• All three components ready for page assembly in Plan 04
• Ready for 18-03-PLAN.md (DecisionList and remaining detail components)
