## Problem
`GET /transactions` throws `InvalidArgumentException: Illegal operator
and value combination` (Sentry
[PHP-LARAVEL-34](https://whisper-money.sentry.io/issues/PHP-LARAVEL-34)
— escalating, 76 occurrences, 2 users).
## Root cause
Laravel's `cursorPaginate()` builds `where(orderColumn, '>',
cursorValue)` for the next page. When sorting by a **nullable** column
(`creditor_name` / `debtor_name`) and the boundary row's value is
`null`, the cursor encodes `null` → `prepareValueAndOperator` rejects
`where(col, '>', null)`. Default sort (`transaction_date`, NOT NULL)
never hits it.
## Fix
When sorting by a nullable column, select `COALESCE(col, '') as
col_sort` and order by the alias. Cursor reads the coalesced
(never-null) value; Laravel rewrites the WHERE to the `COALESCE`
expression. Alias is hidden from serialization.
## Tests
- Reproduces cross-page cursor pagination with null values in the sort
column (500 → 200).
- Asserts the `*_sort` alias is not leaked to the frontend.
Fixes PHP-LARAVEL-34
## Problem
On the transactions page, the **Category** and **Labels** filters were
combined with **AND**. Selecting both a category and a label only showed
transactions that matched the category *and* carried that label.
## Fix
In `Transaction::scopeApplyFilters`, both filters are now wrapped in a
single `where` group with the label condition using `orWhereHas`, so
they combine as **OR**: a transaction matches if it's in a selected
category **or** has a selected label.
- Multi-category OR, category-tree expansion, and the *uncategorized*
option are preserved.
- Other filters (date, amount, account, search) remain AND.
## Tests
Added `category and label filters combine with OR` to
`TransactionFilterTest`. All 34 filter + bulk-update tests pass; pint
clean.
## 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
\`\`\`
## Summary
- add creditor/debtor fields to transactions with raw_data backfill
- store counterparties on bank sync and CSV/XLS imports
- add creditor/debtor filters plus hidden table columns
## Tests
- php artisan test --compact tests/Feature/LocalizationTest.php
tests/Feature/OpenBanking/TransactionSyncServiceTest.php
tests/Feature/TransactionFilterTest.php
- npm test -- resources/js/lib/file-parser.test.ts --run
- vendor/bin/pint --dirty --format agent
Note: `npm run types` still has pre-existing unrelated errors; no
creditor/debtor/import-related errors remained in filtered output.

## Summary
- **Server-side filtering/sorting/search**: With encryption removed, all
transaction filtering, sorting, and full-text search (LIKE on
description + notes) now happens via SQL queries instead of client-side
IndexedDB with decryption
- **Cursor pagination**: Transactions are returned with cursor-based
pagination (default 50 per page, "Load More" pattern) instead of loading
all into IndexedDB
- **Removed IndexedDB dependency**: The main transactions page no longer
depends on Dexie/IndexedDB for data or sync — other pages (categorize,
accounts/show, budgets/show) are unaffected and will be migrated
separately

## Test plan
- [x] Run `php artisan test` — all 523+ tests pass
- [x] Navigate to `/transactions` — paginated results load from server
- [x] Apply each filter type (date, amount, category, account, label,
search) and verify server round-trip
- [x] Test "uncategorized" category filter
- [x] Test combined filters
- [x] Test sorting by date, amount, description (ascending/descending)
- [x] Test "Load More" button for cursor pagination
- [x] Test bulk operations (select some → update, select all filtered →
update)
- [x] Verify URL persistence (refresh page with filters in URL)
- [x] Test search on both description and notes fields
