Add two Claude API-powered endpoints:
- POST /api/ai/extract-deadlines: accepts PDF upload or JSON text, extracts
legal deadlines using Claude tool_use for structured output
- POST /api/ai/summarize-case: generates AI summary from case events/deadlines,
caches result in cases.ai_summary
New files:
- internal/services/ai_service.go: AIService with Anthropic SDK integration
- internal/handlers/ai.go: HTTP handlers for both endpoints
- internal/services/ai_service_test.go: tool schema and serialization tests
Uses anthropic-sdk-go v1.27.1 with Claude Sonnet 4.5. AI service is optional —
endpoints only registered when ANTHROPIC_API_KEY is set.
GET /api/dashboard returns aggregated data:
- deadline_summary: overdue, due this/next week, ok counts
- case_summary: active, new this month, closed counts
- upcoming_deadlines: next 7 days with case info
- upcoming_appointments: next 7 days
- recent_activity: last 10 case events
Uses efficient CTE query for summaries. Also fixes duplicate
writeJSON/writeError declarations in appointments handler.
- Holiday service with German federal holidays, Easter calculation, DB loading
- Deadline calculator adapted from youpc.org (duration calc + non-working day adjustment)
- Deadline CRUD service (tenant-scoped: list, create, update, complete, delete)
- Deadline rule service (list, filter by proceeding type, hierarchical rule trees)
- HTTP handlers for all endpoints with tenant resolution via X-Tenant-ID header
- Router wired with all new endpoints under /api/
- Tests for holiday and calculator services (8 passing)
Tenant management:
- POST /api/tenants — create tenant (creator becomes owner)
- GET /api/tenants — list tenants for authenticated user
- GET /api/tenants/:id — tenant details with access check
- POST /api/tenants/:id/invite — invite user by email (owner/admin)
- DELETE /api/tenants/:id/members/:uid — remove member
- GET /api/tenants/:id/members — list members
New packages:
- internal/services/tenant_service.go — CRUD on tenants + user_tenants
- internal/handlers/tenant_handler.go — HTTP handlers with auth checks
- internal/auth/tenant_resolver.go — X-Tenant-ID header middleware,
defaults to user's first tenant for scoped routes
Authorization: owners/admins can invite and remove members. Cannot
remove the last owner. Users can remove themselves. TenantResolver
applies to resource routes (cases, deadlines, etc.) but not tenant
management routes.
- CaseService: list (paginated, filterable), get detail (with parties,
events, deadline count), create, update, soft-delete (archive)
- PartyService: list by case, create, update, delete
- Auto-create case_events on case creation, status change, party add,
and case archive
- Auth middleware now resolves tenant_id from user_tenants table
- All operations scoped to tenant_id from auth context
- AppointmentService with tenant-scoped List, GetByID, Create, Update, Delete
- List supports filtering by case_id, appointment_type, and date range (start_from/start_to)
- AppointmentHandler with JSON request/response handling and input validation
- Router wired up: GET/POST /api/appointments, PUT/DELETE /api/appointments/{id}
New direction: law firm management (Fristen, Termine, case tracking)
instead of UPC case law search. Updated all references, Go module
path, and deployment info.
