# Implementation Plan

## 1. Types And Tests

- Add emergency DTOs and validators.
- Add `app/api/emergency/emergency-routes.test.ts` first.
- Cover list, create, status update, permission denial, missing organization, invalid input, and missing/cross-organization incident.

## 2. Server Operations And API Routes

- Add `modules/emergency/server/operations.ts`.
- Add `GET`/`POST /api/emergency/incidents`.
- Add `PATCH /api/emergency/incidents/[id]`.
- Use `requirePermission`, active organization checks, structured failures, and audit logs.

## 3. Workspace UI

- Replace `app/(app)/app/emergency/page.tsx`.
- Keep scoped route delegating to the unscoped route.
- Add `modules/emergency/components/EmergencyWorkspaceClient.tsx`.
- Implement metrics, filters, create dialog, and status action buttons.

## 4. Default Data

- Existing default workspace already inserts representative `systemIncidents`.
- Review whether the seed includes open/acknowledged/resolved and critical/warning/info; adjust only if needed.

## 5. Verification

- `pnpm test`
- `pnpm lint`
- `pnpm type-check`
- `pnpm build`

## Rollback Points

- Remove `modules/emergency`, emergency API routes, and page changes.
- No migration rollback expected unless implementation discovers schema changes are required.
