**Last Updated:** 2026-05-10
**Current Version:** v0.24.3
## How to Use This Document
This file is a living document. Agents should:
1. Read this file before proposing changes
2. Add new recommendations with priority levels
3. Never add completed items — move those to HISTORY.md instead
4. Reference this file when dispatching improvement tasks
5. Only Ripley can remove items from this list.
### Priority Format
All items must include the priority emoji in their heading, matching the section they belong to:
| Priority | Emoji | Heading Format |
|----------|-------|---------------|
| CRITICAL | 🔴 | `### 🔴 Title — CRITICAL` |
| HIGH | 🟠 | `### 🟠 Title — HIGH` |
| MEDIUM | 🟡 | `### 🟡 Title — MEDIUM` |
| LOW | 🔵 | `### 🔵 Title — LOW` |
| NICE TO HAVE | 💭 | `### 💭 Title — NICE TO HAVE` |
Items are grouped under their priority section heading (`## 🔴 CRITICAL`, `## 🟠 HIGH`, etc.) and sorted most-impactful-first within each tier.

### Architecture: Business Logic Mixed with Route Handlers
**Priority:** MEDIUM
**Added:** 2026-05-08 by Neo
**Description:**
Many routes contain business logic that should be extracted to service layers.
**Rationale:**
- `bills.js` contains `parseDueDay()`, `parseInterestRate()` — validation logic
- `tracker.js` contains date/range calculations that are reused across routes
- `admin.js` has complex OIDC config building mixed with routing
- `analytics.js` has complex date-building logic (`buildMonths`, `monthKey`, etc.)
**Implementation Notes:**
- Files to modify: Multiple route files + new service files in `/services/`
- Estimated effort: 8 hours
- Proposed structure:
```
/services/billsService.js
/services/trackerService.js
/services/analyticsService.js
/services/authService.js (existing)
/services/oidcService.js (existing)
/services/cleanupService.js (existing)
```
- Route handlers should call services, not contain business logic
### ~~Skip First-Login User Creation When ENV Seeds Users~~ ✅ COMPLETED (v0.22.3)
**Moved to HISTORY.md**
### ~~No Rollback Capability for Failed Migrations~~ ✅ COMPLETED (v0.23.1)
**Moved to HISTORY.md**
### ~~Limited Error Handling and Logging for Migrations~~ ✅ COMPLETED (v0.23.0)
**Moved to HISTORY.md**
**Rationale:**
- Migration errors are silent or unclear
- No logging of which migration failed or why
- No way to diagnose schema inconsistencies
- Risk: slow debugging on production issues
**Implementation Notes:**
- Add detailed logging: `[migration] Applying v0.20.0: Add user_groups table`
- Include timing: `[migration] v0.20.0 completed in 234ms`
- Log precondition checks: `[migration] Checking: table_exists('users')`
- Error log with context: `[migration-error] v0.20.0 failed: UNIQUE constraint failed on users.username`

### 🔵 LOW
### ~~🔵 Export Formats Include Sensitive Bill Credential Fields by Default — LOW~~ ✅ FIXED (v0.24.1)
**Moved to HISTORY.md**
### ~~🔵 Duplicate Local Login Route Increases Auth Drift Risk — LOW~~ ✅ FIXED (v0.23.2)
**Moved to HISTORY.md**
### Add comprehensive unit and integration tests
**Priority:** LOW
**Added:** 2026-05-08 by Scarlett
**Description:**
Currently no unit tests exist for components or hooks. The only testing appears to be functional tests in `test-functional.js`. Component-level testing is missing.
**Rationale:**
Code quality and maintainability. Unit tests catch regressions and document component behavior. Bill Tracker has complex business logic (bill calculations, monthly state, analytics) that should be tested.
**Implementation Notes:**
- Set up Jest + React Testing Library
- Test key components: BillModal, TrackerPage row, BillsTableInner
- Test hooks: useAuth, custom form hooks
- Test utility functions in `client/lib/utils.js`
- Consider vitest for faster test execution
- Add CI integration for test execution
- Files likely to be modified: Add `client/test/` directory, add `jest.config.cjs`
- Estimated effort: 8-12 hours for baseline coverage
### Features: Missing Export for User-Specific Reports
**Priority:** LOW
**Added:** 2026-05-08 by Neo
**Description:**
No built-in way to export filtered data (e.g., "all bills in category X for last 6 months").
**Rationale:**
- `/api/analytics/summary` exists but returns JSON only
- Users cannot generate Excel/PDF reports
- No programmatic way to get export links for specific filters
- `/api/export/user-excel` exports everything, not filtered views
**Implementation Notes:**
- Files to modify: `/home/kaspa/.openclaw/Projects/bill-tracker/routes/export.js`
- Estimated effort: 6 hours
- Add endpoints:
- `GET /api/export/user-excel?category_id=1&start=2026-01&end=2026-06`
- `GET /api/export/user-json?filter=bills&status=missed`
- Add report title/description to export metadata
### Features: Missing Bill Grouping and Reorganization API
**Priority:** LOW
**Added:** 2026-05-08 by Neo
**Description:**
No way to reorder bills, drag-and-drop, or group by custom criteria.
**Rationale:**
- `bills` table has `due_day` ordering but no manual sort order
- Frontend likely orders by `due_day` only
- Users cannot create bill groups or categories for bills
- No way to mark bills as "hidden" or "archived" without deactivating
**Implementation Notes:**
- Files to modify: `/home/kaspa/.openclaw/Projects/bill-tracker/db/schema.sql`, `/routes/bills.js`
- Estimated effort: 6 hours
- Add:
- `sort_order` column to bills table (default NULL, ordered first by sort_order then due_day)
- `PUT /api/bills/reorder` endpoint accepting `{bill_id: new_index}`
- `PUT /api/bills/:id/archived` to soft-dearchive (sets `archived` flag)

### 💭 NICE TO HAVE
### Add consistent form state management pattern
**Priority:** MEH
**Added:** 2026-05-08 by Scarlett
**Description:**
Form state management is inconsistent across components. Some use `useState` for each field, others use form libraries. Validation patterns vary.
**Rationale:**
Consistency and maintainability. A consistent pattern makes it easier to add new forms and reduce bugs.
**Implementation Notes:**
- Consider react-hook-form for complex forms
- Create reusable form field components (InputField, SelectField, etc.)
- Standardize validation approach
- Files likely to be modified: `client/components/*.jsx`
- Estimated effort: 4-6 hours for migration
