# Bill Tracker — Development Log

**Purpose:** Track active development work across all agents. Bishop uses this to update Engineering_Reference_Manual.md.

**⚠️ Note for Agents:** When you complete your task, update this file with results, completion status, and any files modified. Ripley will then notify Bishop to review and decide on manual updates. You have `write` and `edit` access to this file.

## Current Work (In Progress)

### Neo — Migration Version Tracking System
**Status:** ✅ COMPLETED  
**Task ID:** migration-v-tracking-001  
**Priority:** CRITICAL  
**Started:** 2026-05-09 14:45 CDT  
**Completed:** 2026-05-09 15:00 CDT  

**Objective:**
Implement explicit version tracking for database migrations so users can safely upgrade via `git pull && npm start` without migration state issues.

**Work Completed:**
- [x] Create `schema_migrations` tracking table in `db/database.js`
- [x] Refactor `runMigrations()` to query and apply only pending migrations
- [x] Convert existing inline migrations to versioned migration objects
- [x] Add detailed logging for each migration step
- [x] Add `hasMigrationBeenApplied()` and `recordMigration()` helper functions

**Files Modified:**
- `db/database.js` — migration system refactor

**Deliverables:**
- Version tracking implementation complete
- Migrations are now trackable, repeatable, and resilient
- Users can `git pull && npm start` safely

## Historical Context

**Migration System Issues Identified (Neo's Audit):**
1. ❌ CRITICAL: No explicit version tracking
2. ❌ CRITICAL: No transaction wrapping
3. ⚠️ HIGH: No dependency management
4. ⚠️ MEDIUM: No rollback capability
5. ⚠️ MEDIUM: Limited error handling

All issues documented in `/FUTURE.md` with implementation notes.

**Current Work:** Addressing issue #1 (version tracking) as foundation for fixes #2-5.

## Current Work (In Progress)

### Neo — Admin-Only /about Endpoint for FUTURE.md and DEVELOPMENT_LOG.md
**Status:** ✅ COMPLETED  
**Task ID:** admin-about-endpoint-001  
**Priority:** MEDIUM  
**Started:** 2026-05-09 15:25 CDT  
**Completed:** 2026-05-09 15:30 CDT  

**Objective:**  
Create a backend endpoint that serves FUTURE.md and DEVELOPMENT_LOG.md content to admin users only.

**Work Completed:**  
- [x] Created new route file `routes/aboutAdmin.js` with file reading logic  
- [x] Implemented admin-only access using existing `requireAuth` and `requireAdmin` middleware  
- [x] Added proper error handling for file read operations  
- [x] Mounted new route at `/api/about-admin` in `server.js`  
- [x] Used `fs.readFileSync` with UTF-8 encoding for file reading  
- [x] Added path resolution relative to the routes file  

**Files Modified:**  
- `routes/aboutAdmin.js` — New file containing the admin-only endpoint implementation  
- `server.js` — Added route registration for `/api/about-admin`

**Deliverables:**  
- Admins can now access FUTURE.md and DEVELOPMENT_LOG.md content via a secure API endpoint  
- Endpoint returns structured JSON with both file contents  
- Non-admin users get 403 Forbidden  
- Unauthenticated users get 401 Unauthorized  
- File reading errors return 500 with meaningful message
