Full event-driven deadline determination system ported from youpc.org:
Backend:
- DetermineService: walks proceeding event tree, calculates cascading
dates with holiday adjustment and conditional logic
- GET /api/proceeding-types/{code}/timeline — full event tree structure
- POST /api/deadlines/determine — calculate timeline with conditions
- POST /api/cases/{caseID}/deadlines/batch — batch-create deadlines
- DeadlineRule model: added is_spawn, spawn_label fields
- GetFullTimeline: recursive CTE following cross-type spawn branches
- Conditional deadlines: condition_rule_id toggles alt_duration/rule_code
(e.g. Reply changes from RoP.029b to RoP.029a when CCR is filed)
- Seed SQL with full UPC event trees (INF, REV, CCR, APM, APP, AMD)
Frontend:
- DeadlineWizard: interactive proceeding timeline with step-by-step flow
1. Select proceeding type (visual cards)
2. Enter trigger event date
3. Toggle conditional branches (CCR, Appeal, Amend)
4. See full calculated timeline with color-coded urgency
5. Batch-create all deadlines on a selected case
- Visual timeline tree with party icons, rule codes, duration badges
- Kept existing DeadlineCalculator as "Schnell" quick mode
Also resolved merge conflicts across 6 files (auth, router, handlers)
merging role-based permissions + audit trail features.
- Deadline detail page (/fristen/[id]) with status badge, due date,
case context, complete button, and notes
- Appointment detail page (/termine/[id]) with datetime, location,
type badge, case link, description, and notes
- Case event detail page (/cases/[id]/ereignisse/[eventId]) with
event type icon, description, metadata, and notes
- Standalone deadline creation (/fristen/neu) with case dropdown
- Standalone appointment creation (/termine/neu) with optional case
- Reusable Breadcrumb component for navigation hierarchy
- Reusable NotesList component with inline create/edit/delete
- Added Note and RecentActivity types to lib/types.ts
Prevents "M.forEach is not a function" crashes when API returns error
objects or unexpected shapes instead of arrays. Guards all useQuery
consumers with Array.isArray checks and safe defaults for object props.
Files fixed: DeadlineList, AppointmentList, TenantSwitcher,
DeadlineTrafficLights, UpcomingTimeline, CaseOverviewGrid,
AISummaryCard, TeamSettings, and all page-level components
(dashboard, cases, fristen, termine, ai/extract).
Frontend api.ts baseUrl is already "/api", so paths like
"/api/cases" produced "/api/api/cases". Stripped the redundant
prefix from all component calls. Rewrite destination correctly
adds /api/ back for the Go backend.
- Responsive sidebar: collapses on mobile with hamburger menu, slide-in animation
- Skeleton loaders: dashboard cards, case table, case detail page
- Empty states: friendly messages with icons for cases, deadlines, parties, documents
- Error states: retry button on dashboard, proper error message on case not found
- Form validation: inline error messages on case creation form
- German language: fix all missing umlauts (Zurück, wählen, Anhängig, Verfügung, etc.)
- Status labels: display German translations instead of raw status values
- Transitions: fade-in animations on page load, hover/transition-colors on all interactive elements
- Focus states: focus-visible ring for keyboard accessibility
- Mobile layout: stacking for filters, forms, tabs; horizontal scroll for tables
- Extraction results: card layout on mobile, table on desktop
- Missing types: add DashboardData, DeadlineSummary, CaseSummary, ExtractedDeadline etc.
- Fix QuickActions links to use correct routes (/cases/new, /ai/extract)
- Consistent input focus styles across all forms
