# Project State

## Project Reference

## Accumulated Context

### Decisions

Decisions are logged in PROJECT.md Key Decisions table.
Recent decisions affecting current work:

- [Phase 04]: formatCurrency third parameter defaults to 'en', replacing hardcoded 'de-DE'
- [Phase 04]: Custom Tooltip content renderer replicates ChartTooltipContent styling without importing shadcn source
- [Phase 03]: triggerFlash uses two separate state vars (flashRowId/errorRowId) — no race conditions between success and error states
- [Phase 03]: EmptyState is a shared component with all content as props — icon, heading, subtext, and optional CTA
- [Init v1.1]: Three-tier item model (fixed/variable/one-off) matches how users think about recurring vs one-time expenses
- [Phase 05-template-data-model-and-api]: New API-created budget items default to item_tier=one_off at the query layer
- [Phase 05-template-data-model-and-api]: Template creation is lazy: CreateTemplateItem upserts template via ON CONFLICT
- [Phase 05-template-data-model-and-api]: GenerateBudgetFromTemplate returns BudgetExistsError struct for structured 409 response

### Pending Todos

None yet.

### Blockers/Concerns

- [Phase 5]: Need to confirm whether budget_items table already has any type/tag column before writing migration
- [Phase 5]: Template generation endpoint must handle the case where user has no template yet (return empty budget, not error)
