## Why
### Problem
Account balance metrics computation (12-month sparklines, net worth
evolution, currency conversion) was duplicated across three controllers:
- `AccountController` — account index page metrics
- `DashboardController` — dashboard net worth evolution
- `DashboardAnalyticsController` — analytics API net worth evolution
(monthly + daily)
Each had its own `convertBalance()` method, its own BalanceLookup
iteration loop, and its own invested amount handling. Additionally,
`AccountController::show()` re-queried `categories`, `accounts`, and
`banks` — all already available as shared Inertia props from
`HandleInertiaRequests` middleware.
## What
### Changes
- **Extract `AccountMetricsService`** with three public methods:
- `getAccountMetrics()` — per-account balance metrics with sparkline
history (used by accounts index)
- `getNetWorthEvolution()` — monthly net worth evolution with
per-account balances (used by dashboard + analytics API)
- `getNetWorthDailyEvolution()` — daily net worth evolution (used by
analytics API)
- **Refactor `AccountController`** — delegate to
`AccountMetricsService`, remove 3 private methods (`getAccountMetrics`,
`formatMonth`, `convertBalance`)
- **Refactor `DashboardController`** — delegate to
`AccountMetricsService`, remove `getNetWorthEvolution` loop and
`convertBalance`
- **Refactor `DashboardAnalyticsController`** — delegate to
`AccountMetricsService` for `netWorthEvolution` and
`netWorthDailyEvolution`, remove `convertBalance`, `getBalanceAt`,
`getInvestedAmountAt` private methods
- **Remove duplicate queries from `AccountController::show()`** —
`categories`, `accounts`, `banks` are already shared by middleware
- **Add missing `encrypted` column** to the middleware's shared
`accounts` query so components that need it (EditAccountDialog, etc.)
receive it
### Impact
- **Net -87 lines** across 5 files (285 added in new service, 372
removed from controllers)
- Single source of truth for balance metrics computation
- Eliminated 3 copies of `convertBalance()` and 2 copies of the net
worth evolution loop
- Removed 3 redundant database queries from account show page
## Verification
### Tests
- All 84 related tests pass (AccountController, AccountBalance,
Dashboard, DashboardAnalytics, BalanceLookup, CashflowAnalytics) with
529 assertions
- No test changes needed — the refactoring preserves exact output shapes
## Why
### Problem
The dashboard page takes ~4 seconds to load for users with many balance
records. Profiling revealed 29 queries across the initial page load + 3
separate API calls, a 576 KB wasted payload from unused bank records,
and a critical 3.7s bottleneck in `BalanceLookup` correlated subqueries.
## What
### Changes
**Query optimizations:**
- Replace correlated `MAX()` subqueries in `BalanceLookup` with
derived-table `joinSub` pattern — **48x faster** (3,693ms → 77ms) on
accounts with thousands of balance records
- Replace `whereHas` (EXISTS subqueries) with JOINs in
`DashboardAnalyticsController` and `CashflowAnalyticsController` — ~3x
faster per query
- Cache encryption check results in `HandleInertiaRequests` middleware
to avoid 2 duplicate queries per request
**Payload & request reduction:**
- Remove dead `banks` query from `DashboardController` (2,365 records,
576 KB never used by frontend)
- Remove duplicate `categories` and `accounts` queries already provided
by middleware shared props
- Consolidate 3 separate `fetch()` API calls into Inertia v2
`Inertia::defer()` props grouped under `'dashboard'` (single follow-up
request with skeleton fallbacks)
**Frontend:**
- Replace `useDashboardData` fetch hook with `usePage()` props +
`<Deferred>` components
- Convert `CashflowSummaryCard` from internal fetch to prop-based
- Use `router.reload({ only: [...] })` for balance update refetch
### Performance summary
| Metric | Before | After |
|--------|--------|-------|
| Initial page queries | 16 | 12 |
| Follow-up HTTP requests | 3 separate API calls | 1 Inertia deferred |
| BalanceLookup time | 3,693ms | 77ms |
| Wasted payload | 576 KB | 0 |
## Verification
### Tests
All 633 feature tests pass, including 40 dashboard/cashflow-specific
tests.
## Why
Investment and retirement accounts show balance over time, but there's
no way to see how much money was actually put in versus how much is
current value. Users can't tell at a glance whether their investments
are up or down.
## What
Adds an "invested amount" tracking system across the full stack:
**Backend**
- New `invested_amount` column on `account_balances` (nullable
bigInteger, cents, per-date)
- Auto-sync from providers: Indexa Capital (instruments_cost +
cash_amount), Bitpanda (fiat deposit/withdrawal history), Binance
(90-day windowed deposit/withdrawal with crypto→fiat conversion)
- Manual input support via Update Balance dialog
- Historical invested amount data in all balance evolution APIs (net
worth, account detail)
**Frontend**
- Dashed line on sparkline charts (dashboard + accounts page) showing
per-point historical invested amount alongside balance
- Dashed line on account detail charts (daily AreaChart + monthly
ComposedChart)
- Tooltips with labeled rows: Balance, Invested, Gain/loss (color-coded)
- Invested amount column in balances history modal
- Invested amount field in balance import wizard (CSV mapping)
- Demo account seeder updated with invested amount data

## Why
### Problem
Users with accounts in multiple currencies see raw balances on the net
worth chart without any conversion. A user with a USD-denominated
profile who also holds EUR and GBP accounts sees misleading totals — the
chart simply sums cents across currencies as if they were the same unit.
## What
### Changes
- **`ExchangeRateService`** — New service that wraps
`CurrencyConversionService` with DB-level caching. Checks the
`exchange_rates` table first, falls back to the external CDN API on
cache miss, and stores the full rate blob for future lookups.
- **`exchange_rates` migration + model** — New table with
`(base_currency, date)` unique constraint storing JSON rate blobs.
Includes factory.
- **`CurrencyConversionService`** — Made `getRatesForCurrency()` public
so `ExchangeRateService` can delegate to it.
- **`DashboardAnalyticsController`** — `netWorthEvolution` and
`netWorthDailyEvolution` endpoints now convert every account balance
from `account.currency_code` to `user.currency_code`. Response includes
`currency_code` field and `_original` data for foreign-currency
accounts.
- **Future date capping** — `ExchangeRateService::getRates()` caps any
future date to today, since the currency API only serves historical
rates. Prevents 500 errors when the chart requests end-of-month rates
for the current (incomplete) month.
- **Frontend charts** — Simplified to single-currency display. Removed
multi-currency `TotalDisplay` component; the chart header and tooltip
now show amounts in the user's currency. Foreign-currency accounts show
their original amount inline in the tooltip (e.g., "€2,000.00 →
$2,222.22").
- **`valueFormatter` type fix** — Changed return type from `string` to
`React.ReactNode` in chart component interfaces to match actual usage
with `AmountDisplay`.

## Summary
Adds daily granularity support to the dashboard Net Worth Evolution
chart, mirroring the daily balance feature added for individual account
pages in #135.
## Why
The net worth chart only supported monthly granularity, making it
impossible to see short-term net worth fluctuations. Users who track
daily balances need a way to visualize day-over-day net worth changes
across all accounts.

## Summary
- Adds a **Monthly / Daily granularity toggle** to the account balance
evolution chart on account pages
- Daily view renders as an **area chart** (line with gradient fill)
showing the last 30 days, while monthly keeps the existing bar chart
- All 3 chart view modes (stacked, period-over-period,
period-over-period %) work in both granularities
- Chart view toggle **tooltips update dynamically** based on granularity
(e.g. "Month over month change" → "Day over day change")
- Backend fills gaps in sparse `account_balances` data by carrying
forward the last known balance day-by-day
- Includes 3 new Pest tests for the daily endpoint (data points,
gap-filling, forbidden access)

## Summary
- Store account names in plaintext instead of encrypting them
client-side. Encryption remains only for transaction descriptions and
notes.
- Existing encrypted account names are silently migrated when the user
unlocks their encryption key, via a new `useDecryptAccountNames` hook
that calls API endpoints to update each account.
- New `AccountName` component handles rendering both encrypted (legacy)
and plaintext accounts across the app.
## Test plan
- [x] Create a new account — name should be stored in plaintext
(`encrypted = false`, `name_iv = null`)
- [x] Unlock encryption key with existing encrypted accounts — they
should auto-migrate silently
- [x] After migration, verify accounts show `encrypted = false` in DB
and names are readable plaintext
- [x] Edit a migrated account — should work without encryption
- [x] Verify all account name displays work across dashboard, account
details, transactions, settings
