# Plan 18-03 Summary

## Result: COMPLETE

**Tasks:** 2/2 completed
**Duration:** ~3 min

## What was built

### DecisionList component
- Collapsible list of key decisions in a Card with "Key Decisions" header
- Each decision individually expandable with ChevronDown/ChevronRight indicators
- Internal state tracks expanded indices via `Set<number>`
- Show more/less button when decisions exceed `maxVisible` (default 3)
- Empty state placeholder: "No decisions recorded"
- File: `packages/web/src/components/DecisionList.tsx`

### TaskDetailModal component
- Controlled Dialog (open when `task !== null`) following CreateInitiativeDialog pattern
- Metadata grid: Status (StatusBadge), Priority, Phase, Type, Agent
- Description section with fallback to "No description"
- Dependencies section listing dependency names with status badges
- Blocks section listing dependent names with status badges
- Queue Task button: enabled only when status is 'pending' and all dependencies completed
- Stop Task button: enabled only when status is 'in_progress'
- SerializedTask interface for tRPC Date-to-string wire format
- File: `packages/web/src/components/TaskDetailModal.tsx`

## Decisions

- 18-03: SerializedTask type mirrors SerializedInitiative pattern (Date fields become string over JSON)
- 18-03: Both components are purely presentational with callback props (no tRPC calls inside)
