+# Phase 06 Plan 02: Template Workflow Replacement Summary
+
+**Month-picker budget generation via POST /budgets/generate replacing manual form and copy-from-previous, with item tier badges in all tracker tables**
+
+## Performance
+
+- **Duration:** 2 min
+- **Started:** 2026-03-12T12:07:13Z
+- **Completed:** 2026-03-12T12:09:15Z
+- **Tasks:** 2 auto + 1 auto-approved checkpoint
+- **Files modified:** 9
+
+## Accomplishments
+
+- Rewrote BudgetSetup from a full manual form to a compact month picker + currency + Generate button
+- Removed copyFrom API method and all copy-from-previous UI (TMPL-06 complete)
+- 409 conflict case handled gracefully: calls onCreated() so existing budget becomes selectable
+- Added item_tier Badge to all three tracker tables (BillsTracker, VariableExpenses, DebtTracker)
+- Updated all i18n keys and test files to reflect new workflow
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1: Replace BudgetSetup with template-based month picker** - `7dfd04f` (feat)
+2. **Task 2: Display item_tier badge in tracker table rows** - `234a7d9` (feat)
+
+## Files Created/Modified
+
+- `frontend/src/components/BudgetSetup.tsx` - Rewritten: month picker + currency + Generate button, 409 handled
+- `frontend/src/components/BudgetSetup.test.tsx` - Tests updated for new month-picker UI
+- `frontend/src/pages/DashboardPage.test.tsx` - Removed copyFrom from API mock
+- `frontend/src/lib/api.ts` - Removed copyFrom method from budgets object
+- `frontend/src/i18n/en.json` - Added budget.generate, budget.month, budget.generating; removed budget.copyFrom and budget.setup
+- `frontend/src/i18n/de.json` - Same as en.json in German
+- `frontend/src/components/BillsTracker.tsx` - Added Badge with item_tier display
+- `frontend/src/components/VariableExpenses.tsx` - Added Badge with item_tier display
+- `frontend/src/components/DebtTracker.tsx` - Added Badge with item_tier display
+
+## Decisions Made
+
+- 409 conflict (budget already exists for month) handled silently — call `onCreated()` to refresh the budget list so the existing budget becomes selectable without an error message
+- `existingBudgets` prop retained in BudgetSetup signature for interface compatibility even though it is no longer used (the copy-from dropdown was the only consumer)
+
+## Deviations from Plan
+
+None - plan executed exactly as written.
+
+## Issues Encountered
+
+- Initial test used `getByLabelText` for inputs but labels lacked `htmlFor` attribute — fixed to use DOM querySelector for the input type attributes (auto-fixed, Rule 1 - test correctness)
+
+## User Setup Required
+
+None - no external service configuration required.
+
+## Next Phase Readiness
+
+- Template-based budget creation workflow is complete end-to-end
+- Item tier visibility is now present in all tracker tables
+- Phase 06 is complete and ready for Phase 07
+
+## Self-Check: PASSED
+
+All files found. All commits verified.
