# Policies Integration

## Purpose

The handbook and policies workflow reads and mutates policy documents through the backend `documents` API.

## Frontend Structure

- Framework wrapper: `frontend/src/components/frameworks/HandbookPolicy.tsx`
- Focused view components: `frontend/src/components/policies/`
- Business hooks: `frontend/src/business/policies/hooks.ts`
- Business page workflow hook: `frontend/src/business/policies/pageHooks.ts`
- Business mappers: `frontend/src/business/policies/mappers.ts`
- Business selectors: `frontend/src/business/policies/selectors.ts`
- API layer: `frontend/src/shared/api/documents.ts`
- DTO types: `frontend/src/shared/types/documents.ts`
- Policy types/constants: `frontend/src/shared/types/policies.ts`, `frontend/src/shared/constants/policies.ts`

## Backend Contract

The slice uses the existing backend route:

- `GET /api/documents?category=policy`
- `POST /api/documents`
- `PUT /api/documents/:id`
- `DELETE /api/documents/:id`

Policy records are represented as `documents` rows:

- `category`: fixed to `policy`
- `entity_type`: fixed to `organization`
- `entity_reference`: policy category displayed in the handbook
- `name`: policy title
- `notes`: policy content
- `uploaded_at`: recorded mutation timestamp

## Behavior

- `HandbookPolicy` is a thin wrapper that calls `usePoliciesPage` and renders `PoliciesView`.
- Policy UI is split into focused components for the hero, create form, filters, status panels, list, cards, and empty state.
- Policy forms and filters use shared UI primitives: `Button`, `Input`, `Textarea`, `NativeSelect`, and `StatePanel`.
- Policy list/create/update/delete flows use React Query hooks and backend error states.
- Director and superintendent roles can manage policies in the frontend.
- Acknowledgement state remains session-local because the backend does not yet expose a policy acknowledgement contract.

## Verification

- `npm run build` passes.
- `npm run lint` passes for the current frontend baseline.
- `npm run typecheck` passes.
- `npm run test` passes.
