Build Feature Slice

Implement the feature requested in $ARGUMENTS as a vertical slice.

Required process

1. Read the relevant docs:

   • docs/SPEC.md
   • docs/design.md
   • docs/API.md
   • docs/DATABASE.md
   • docs/SECURITY_AND_PRIVACY.md

2. Identify affected areas:

   • packages/shared
   • apps/api
   • apps/web

3. Define or update shared types first.

4. Implement backend changes if needed:

   • database schema
   • module
   • validation
   • endpoint
   • DTO
   • tests

5. Implement frontend changes:

   • API service
   • components
   • page integration
   • loading state
   • empty state
   • error state
   • mobile responsive behavior

6. Check emergency rules:

   • source visible
   • last update visible
   • verification status visible
   • no private data exposed
   • no map-only critical flow

7. Run:

   • pnpm typecheck
   • pnpm lint
   • pnpm test
   • pnpm build

8. Ask qa-code-reviewer to review the result.
