## Goal Achievement

### Observable Truths (from Success Criteria + Plan must_haves)

| #  | Truth                                                                                                              | Status     | Evidence                                                                                            |
|----|--------------------------------------------------------------------------------------------------------------------|------------|-----------------------------------------------------------------------------------------------------|
| 1  | Dashboard displays expense donut chart with center total label, active sector hover expansion, and custom legend   | VERIFIED   | `ExpenseDonutChart.tsx` — `<Label>` with `formatCurrency`, `activeShape={renderActiveShape}`, custom `<ul>` legend |
| 2  | Dashboard displays grouped vertical bar chart comparing income budgeted vs actual                                  | VERIFIED   | `IncomeBarChart.tsx` — `<BarChart>` (default vertical) with `budgeted` and `actual` `<Bar>` elements |
| 3  | Dashboard displays horizontal bar chart comparing budget vs actual spending by category type                       | VERIFIED   | `SpendBarChart.tsx` — `<BarChart layout="vertical">` with swapped XAxis/YAxis types                 |
| 4  | All three charts consume colors from CSS variable tokens, no hardcoded hex values                                  | VERIFIED   | Zero hex literals found in charts dir; all fills use `var(--color-*-fill)`, `var(--color-over-budget)`, `var(--color-budgeted)` |
| 5  | Charts render correctly with zero-item budgets (empty state)                                                       | VERIFIED   | All three charts check `data.length === 0` and render `<ChartEmptyState>`; donut additionally handles `totalExpenses === 0` with neutral ring |
| 6  | User can navigate between budget months without leaving the page, charts/cards update                              | VERIFIED   | `useMonthParam` reads/writes `?month=YYYY-MM` URL param; `DashboardPage` re-derives `currentBudget` on every `month` change; all chart data is `useMemo([items, t])` |
| 7  | useMonthParam hook reads month from URL search params and falls back to current month                              | VERIFIED   | `useMonthParam.ts` — `searchParams.get("month") || currentMonth` fallback, year-rollover-safe `navigateMonth` |
| 8  | MonthNavigator renders prev/next arrows and a dropdown listing all budget months                                   | VERIFIED   | `MonthNavigator.tsx` — two `Button variant="ghost" size="icon"` + `Select` with `SelectItem` map over `availableMonths` |
| 9  | Navigating months updates URL without page reload                                                                  | VERIFIED   | `setSearchParams((prev) => { prev.set("month", ...) })` callback form — pushes to history, no full reload |
| 10 | ChartEmptyState renders a muted placeholder with message text inside a chart card                                  | VERIFIED   | `ChartEmptyState.tsx` — `min-h-[250px] flex items-center justify-center bg-muted/30 border-dashed` with `<p className="text-sm text-muted-foreground">` |
| 11 | i18n keys exist for month navigation and chart labels in both EN and DE                                            | VERIFIED   | `en.json` and `de.json` both contain: `monthNav`, `noData`, `expenseDonut`, `incomeChart`, `spendChart`, `budgeted`, `actual`, `noBudgetForMonth`, `createBudget`, `generateFromTemplate` |
| 12 | Dashboard page reads month from URL and looks up corresponding budget                                              | VERIFIED   | `DashboardPage` calls `useMonthParam()`, then `budgets.find(b => b.start_date.startsWith(month))` |
| 13 | MonthNavigator appears in PageShell action slot with dropdown of all available budget months                       | VERIFIED   | `<PageShell action={<MonthNavigator availableMonths={availableMonths} t={t} />}>` — line 221 |
| 14 | DashboardSkeleton mirrors the new 3-column chart layout                                                            | VERIFIED   | `DashboardSkeleton.tsx` — `grid gap-6 md:grid-cols-2 lg:grid-cols-3` with 3 skeleton chart cards (`h-[250px]`) |

|--------------|---------------------------|--------------------------------------------------------------------------------------------------|-----------|-----------------------------------------------------------------|
| UI-DASH-01   | 02-01-PLAN, 02-03-PLAN    | Redesign dashboard with hybrid layout — summary cards, charts, and collapsible category sections | SATISFIED | Dashboard has SummaryStrip, 3-column chart grid, URL month nav, empty-month prompt. (Collapsible sections are Phase 3 scope.) |
| UI-BAR-01    | 02-02-PLAN, 02-03-PLAN    | Add bar chart comparing income budget vs actual                                                  | SATISFIED | `IncomeBarChart` renders grouped vertical bars; wired into DashboardPage with memoized `incomeBarData` |
| UI-HBAR-01   | 02-02-PLAN, 02-03-PLAN    | Add horizontal bar chart comparing spend budget vs actual by category type                       | SATISFIED | `SpendBarChart` uses `layout="vertical"` for horizontal bars; wired into DashboardPage with memoized `spendBarData` |
| UI-DONUT-01  | 02-02-PLAN, 02-03-PLAN    | Improve donut chart for expense category breakdown with richer styling                           | SATISFIED | `ExpenseDonutChart` replaces old flat `PieChart`; has center label, active hover, custom legend, CSS variable fills |

**Notes:** No REQUIREMENTS.md file exists in `.planning/`; requirements are defined inline in ROADMAP.md Requirements Traceability section. All four Phase 2 requirement IDs (UI-DASH-01, UI-BAR-01, UI-HBAR-01, UI-DONUT-01) are fully covered. No orphaned requirements found.

## Anti-Patterns Found

| File                                            | Line | Pattern                                    | Severity | Impact              |
|-------------------------------------------------|------|--------------------------------------------|----------|---------------------|
| `ExpenseDonutChart.tsx`                         | 55   | Code comment: "No data at all: show empty state placeholder" | Info  | Legitimate comment, not a stub — code below the comment is fully implemented |

No blocker or warning-level anti-patterns found. No `TODO`/`FIXME`/`HACK` comments. No hardcoded hex values. No empty implementations (`return null` is used only as a guarded early return in `DashboardContent` when `!budget` after the loading state resolves, which is correct behavior).

---

## Build Verification

`bun run build` passes with zero TypeScript errors. One non-blocking Vite CSS warning regarding `fill: var(...)` (a known Vite/CSS parser quirk for dynamically constructed CSS variable names in Tailwind utility classes) — this does not affect runtime behavior.

---

## Human Verification Required

### 1. Donut hover expansion

**Test:** Load the dashboard with a budget that has expense items. Hover over a donut sector.
**Expected:** The hovered sector visually expands outward (outer radius grows by 8px) — active sector animation is confirmed working.
**Why human:** The `activeShape` render function is wired (`onMouseEnter` sets `activeIndex`), but visual correctness of the Recharts `Sector` expansion requires runtime rendering.

### 2. Month navigation updates all charts

**Test:** Navigate to a month with a budget, then use the prev/next arrows to reach a different budget month.
**Expected:** All three charts and the SummaryStrip update to show the new month's data without a page reload.
**Why human:** Data reactivity chain (URL param -> budget lookup -> useBudgetDetail -> chart props) is structurally correct but requires live data to confirm end-to-end.

### 3. Empty month prompt appears and functions

**Test:** Navigate to a month with no existing budget using the MonthNavigator.
**Expected:** "No budget for this month" text appears with "Create Budget" and "Generate from Template" buttons. Clicking each invokes the respective mutation.
**Why human:** The `!currentBudget` branch is fully coded but requires navigation to a month with no budget to trigger in a live environment.

### 4. Zero-amount donut state

**Test:** Load a budget where all expense category items have 0 actual amounts.
**Expected:** A full neutral gray ring is displayed with "$0" (or equivalent formatted currency) in the center — no legend items shown below.
**Why human:** Requires a real budget with zero actuals to trigger the `isAllZero` branch in `ExpenseDonutChart`.

---

## Gaps Summary

No gaps. All must-haves are verified at all three levels (exists, substantive, wired). The build passes cleanly. Four items are flagged for optional human testing to confirm runtime visual behavior, but all underlying code paths are correctly implemented.
