## Summary
Adds nested categories (parent → child, up to **3 levels**) across the
app. Children inherit their parent's type and cashflow direction, and
every category selector now renders the hierarchy as an indented tree.
Gated behind the `CategoryTree` Pennant flag (off by default).
## Backend
- **Migration**: nullable self-referencing `parent_id`; uniqueness
scoped per-parent via a `parent_unique_marker` virtual column (root
names stay unique). New composite unique created before dropping the old
one so the `user_id` FK keeps a supporting index.
- **`CategoryTree` service**: descendant/ancestor resolution, depth &
cycle checks, type cascade, subtree deletion.
- **Validation**: depth limit, cycle prevention, inherited + locked
child type.
- **Delete strategies**: reparent (default), promote to root, or cascade
(uncategorizes affected transactions).
- **Transaction filter** expands a selected parent to its descendants.
- **Cashflow Sankey & breakdown** roll up to top-level parents with
click-to-drill (children + a parent "direct" node).
- **Budgets** tracking a parent also count their children's
transactions.
- **Unified** the frontend category query behind
`Category::forDisplay()` / `FRONTEND_COLUMNS` (8 call sites) so every
selector receives the full Category shape, including `parent_id`.
## Frontend
- New `category-tree.ts` helpers (build/flatten/descendants/path,
tree-aware selection toggle + tri-state).
- **Settings page**: indented tree, sortable by name/color/type
(siblings sorted, hierarchy preserved), parent picker, delete-strategy
dialog.
- **Combobox** (transaction table cell + edit/create modal + parent
picker): indented tree, search keeps matches with their ancestors.
- **Transaction filter**: indented tree, tri-state cascading selection
(parent ↔ children), themed checkboxes, selected branches float to top
on open, ancestor-aware search.
- **Categorizer palette** and **budget multi-select**: same indented
tree + ancestor-aware search.
- **Sankey**: click a parent node to drill into its children, with
breadcrumb.
- Pennant `CategoryTree` flag gates the parent UI.
## Tests
- Pest: model/validation, delete strategies, filter expansion, cashflow
rollup/drill, budget child inclusion.
- Vitest: tree-aware selection logic.
- All green; Pint / ESLint / Prettier clean.
## Rollout
Flag is off by default — enable per user with:
\`\`\`
php artisan feature:enable "App\\Features\\CategoryTree" you@example.com
\`\`\`
## Why
**Problem:** Bulk re-evaluation of transactions against smart rules was
broken because the code required an encryption key that no longer exists
in the app. Additionally, the rule builder UI had unnecessary complexity
(priority field, labels/tags, date/category/notes conditions) that added
cognitive load without value. Currency amounts were also always
formatted with US conventions regardless of the user's locale.
## What
**Automation rules – re-evaluation fix:**
- Remove encryption key requirement from `evaluateRules`,
`evaluateRulesForTransactions`, `evaluateRulesForNewTransaction`, and
`prepareTransactionData` (accept `CryptoKey | null`)
- Drop `isKeySet` guards from single-transaction and bulk re-evaluate
handlers in `transaction-list.tsx` and `transaction-actions-menu.tsx`
- Simplify `use-re-evaluate-all-transactions.tsx` to pass `null` as key
directly
**Automation rules – UI cleanup:**
- Hide priority field from create/edit dialogs (still sends `priority:
0` / `rule.priority` to satisfy backend validation)
- Remove labels/tags from create/edit dialogs, actions column, and table
display
- Remove `date`, `category`, and `notes` from rule condition field
options in `rule-builder-utils.ts`
- Add `opacity-30` to disabled X button when only one condition/group
remains
**Amount localization:**
- Replace hardcoded `'en-US'` with `useLocale()` in `AmountDisplay` so
symbol position and number format follow the user's locale (e.g.
`89.705,00 €` in Spanish)
## Verification
- 38/38 `AutomationRuleTest` + `AutomationRuleEvaluationTest` tests pass
- Re-evaluation works without an encryption key set
- Spanish locale users see `89.705,00 €` instead of `€89,705.00`
## Summary
- Removed all `setupEncryptionKey()` / `visitWithEncryptionKey()` calls
from browser tests — encryption key setup in localStorage is no longer
needed since new users don't have encryption
- Removed `encryption_salt` from `UserFactory::onboarded()` state and
`OnboardingFlowTest` user creation
- Removed `name_iv` from `Account::factory()` calls in
`BankAccountsTest`
- Deleted `DemoEncryptionService` and its unit test — demo command now
stores plaintext account names and transaction descriptions
- Removed `demoEncryptionKey` Inertia shared prop and `encryption_key`
from demo config
- Removed encryption helper methods from `TestCase.php` and global
`setupEncryptionKey()` from `Pest.php`
## Test plan
- [x] Run `php artisan test --exclude-testsuite=Browser` — all
non-browser tests pass
- [x] Run `php artisan test --testsuite=Browser` — browser tests pass
without encryption key setup
- [x] Run `php artisan demo:reset` — demo account created with plaintext
data
- [x] Verify existing encryption migration tests still pass
(`EncryptionTest`, `DecryptTransactionsTest`,
`PlaintextTransactionsTest`)
## Summary
Implements a complete user onboarding flow that guides new users through
setting up their account after registration.
## Features
- **Step-by-step wizard UI** with progress indicator and smooth
animations
- **E2E Encryption setup** with password strength indicator and
explanation of how encryption works
- **Account creation** supporting all account types (checking, savings,
credit card, investment, pension)
- **Category customization** with explanation of category types
(expenses, income, transfer)
- **Smart rules explanation** covering why there is no AI
auto-categorization (privacy & E2EE)
- **Transaction/balance import** based on account type
- **Sync integration** to ensure data consistency with backend

- Created `EnsureOnboardingComplete` middleware for redirect logic
- Created `OnboardingController` with index and complete actions
- Custom `RegisterResponse` to redirect new users to onboarding
- Updated `AccountController::store` to return JSON for fetch requests
### Frontend
- `OnboardingLayout` - fullscreen layout with step progress
- `useOnboardingState` hook - manages step navigation and state
- 12 step components for each onboarding screen
- Backend sync after account creation and imports
### Tests
