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.
