- Add step-based dependency to useTaskDiffStats hook to trigger refetch when task steps change
- Implement 5-second polling interval for live diff statistics updates
- Add comprehensive test coverage for polling behavior and step-change detection
- Update TaskCard to pass step information to useTaskDiffStats
- Add TaskCard unit tests for diff statistics display
- Import resolvePrompt and PromptOverrideMap from @fusion/core
- Add promptOverrides parameter to all agent creation paths:
- createMissionInterviewSession
- submitMissionInterviewResponse
- retryMissionInterviewSession
- initializeAgent
- createMissionInterviewAgent
- ensureMissionInterviewAgent
- Use resolvePrompt('planning-system', promptOverrides) for effective prompt
- Fall back to MISSION_INTERVIEW_SYSTEM_PROMPT when override absent
- Update module docs to reflect prompt override behavior
- Add viewport-gated fetching to TaskCard component so only visible cards load their data
- Implement lightweight memo comparison to prevent unnecessary re-renders
- Add lazy enable gates to useSessionFiles and useTaskDiffStats hooks with caching
- Add comprehensive tests for useSessionFiles and useTaskDiffStats hooks
- Document viewport-gated loading patterns in memory and dashboard-load performance docs
- Create useTaskDiffStats hook to extract and compute diff stats from task data
- Use hook in TaskCard component for consistent done file count display
- Add diffStats priority tests ensuring diff stats take precedence over steps
- Add useTaskDiffStats mock and comprehensive unit tests for the hook
