# Upgrade Attempt: esbuild (v0.27.2 -> v0.27.3)

**Status:** FAILED (Reverted)
**Date:** 2026-02-17

## Details
Attempted to upgrade `esbuild` from `0.27.2` to `0.27.3`.

## Test Results
- `npm run build`: **PASSED**
- `npm run test:unit`: **PASSED**
- `npm run test:dm:integration`: **PASSED**
- `npm run test:e2e`: **FAILED** (Environment Issue)

## Failure Analysis
The E2E tests failed because the Playwright browser binaries were not found in the CI environment:
```
Error: browserType.launch: Executable doesn't exist at /home/jules/.cache/ms-playwright/chromium_headless_shell-1208/chrome-headless-shell-linux64/chrome-headless-shell
```

## Next Steps
- Ensure the CI/Agent environment has `npx playwright install` run before attempting upgrades that require E2E verification.
- Once browsers are available, retry the upgrade.
