## 🚪 Why?
### Problem
PHPStan was running with a baseline of 56 suppressed errors, meaning
static analysis was not enforcing type safety across a significant
portion of the codebase. These errors were real type mismatches,
redundant null-safety operators, and incorrect PHPDoc annotations that
could mask bugs and make the code harder to reason about.
## 🔑 What?
### Changes
- Add `@property` PHPDoc annotations to `Account`, `BankingConnection`,
`ExchangeRate`, and `Transaction` models so Enum casts and typed columns
are visible to PHPStan
- Add `instanceof User` guards in `ScheduleDripEmailsListener`,
`SyncUserToResendListener`, and `FortifyServiceProvider` to properly
narrow `Authenticatable` to `App\Models\User`
- Remove redundant `?? false` and unnecessary nullsafe `?->value` in
`HandleInertiaRequests`
- Fix `SyncBankingConnectionJob`: use `->name` instead of `?->name` on
an always-loaded `bank` relation
- Remove `is_countable()` guard in `BalanceLookup` (parameter is always
`Collection|array`, both countable)
- Remove `?? []` / `?? default` fallbacks on fully-typed array keys
across `BalanceSyncService`, `BinanceBalanceSyncService`,
`BinanceClient`, `BitpandaBalanceSyncService`, `BitpandaClient`,
`IndexaCapitalClient`, `IndexaCapitalBalanceSyncService`, and
`AuthorizationController`
- Fix `BinanceClient::publicClient()` `retry()` call: use `when:` named
argument and `\Throwable` type hint to match `PendingRequest::retry()`
signature
- Update `IndexaCapitalClient::getPerformance()` `@return` to include
`portfolios` and `net_amounts` keys; simplify sync service to remove
dead null checks
- Replace nullsafe chain with ternary in `BudgetPeriodService`
- Replace `match` statement in `SetupMainUser` with `if/else` to
eliminate always-true comparison
- Clear `phpstan-baseline.neon` entirely (was 56 suppressed errors, now
0)
## ✅ Verification
### Tests
- Existing tests pass: PHPStan level 5 reports 0 errors with empty
baseline
## Summary
- Allow users to connect their Indexa Capital (Spanish robo-advisor)
account via API token
- Adds "Indexa Capital" option when selecting Spain in the bank
connection dialog
- Token-based auth flow: user enters API token (instead of OAuth
redirect), validated against Indexa API, stored encrypted
- Syncs portfolio balance only (no transactions) from the
`/accounts/{id}/performance` endpoint
- Accounts created as `Investment` type
- Reuses existing account mapping flow when the `account-mapping`
feature flag is active
- Disconnect flow skips session revocation for Indexa (no OAuth session
to revoke)
## New files
- `IndexaCapitalClient` — HTTP client for Indexa Capital API
(`X-AUTH-TOKEN`)
- `IndexaCapitalBalanceSyncService` — Syncs portfolio value into
`account_balances`
- `IndexaCapitalController` — Token validation + connection creation
- `ConnectIndexaCapitalRequest` — Form request validation
- Migration adding encrypted `api_token` column to `banking_connections`
## Test plan
- [x] 6 controller tests (connect, invalid token, mapping, feature flag,
validation, multi-account)
- [x] 4 balance sync tests (sync, update, skip, missing field)
- [x] 3 sync job tests (balance-only, no expire, no email for Indexa)
- [x] 1 disconnect test (no revokeSession for Indexa)
- [x] All 530 existing tests still pass
