## Code Review Fixes 1. **Test Assertion Error (line 292)** - CRITICAL - Fixed incorrect assertion in sqljs-memory-leak test - Changed from `expect(saveCallback).toBeLessThan(10)` - To: `expect(saveCallback.mock.calls.length).toBeLessThan(10)` - ✅ Test now passes (12/12 tests passing) 2. **Upper Bound Validation** - Added maximum value validation for SQLJS_SAVE_INTERVAL_MS - Valid range: 100ms - 60000ms (1 minute) - Falls back to default 5000ms if out of range - Location: database-adapter.ts:255 3. **Railway Dockerfile Optimization** - Removed build tools after installing dependencies - Reduces image size by ~50-100MB - Pattern: install → build native modules → remove tools - Location: Dockerfile.railway:38-41 4. **Defensive Programming** - Added `closed` flag to prevent double-close issues - Early return if already closed - Location: database-adapter.ts:236, 283-286 5. **Documentation Improvements** - Added comprehensive comments for DEFAULT_SAVE_INTERVAL_MS - Documented data loss window trade-off (5 seconds) - Explained constructor optimization (no initial save) - Clarified scheduleSave() debouncing under load 6. **CHANGELOG Accuracy** - Fixed discrepancy about explicit cleanup - Updated to reflect automatic cleanup via function scope - Removed misleading `data = null` reference ## Verification - ✅ Build: Success - ✅ Lint: No errors - ✅ Critical test: sqljs-memory-leak (12/12 passing) - ✅ All code review findings addressed 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
