## ⚠️ Failure Cascade Detected

**22 `[aw] * failed` issues** were filed within the last **60 minutes** (since Wed, 16 Sep 2026 03:54:50 GMT).

This volume suggests a common root cause (e.g., lockfile drift, provider outage, infrastructure change) rather than isolated workflow failures.

### What to Do

1. Identify the common root cause (check recent infra changes, provider status, lockfile drift).
2. Once the root cause is resolved, batch-close the `cascade-suspected`-labeled issues.
3. Close this rollup issue when the cascade is resolved.

### Labels

Each individual failure issue in the cascade window has been labeled `cascade-suspected` so you can filter and batch-close them once the root cause is patched.

Start by reviewing the 22 linked failure issues and their cascade-suspected labels. Check recent infrastructure changes, provider status, and lockfile drift to identify the common cause. Done means the root cause is resolved, affected issues are batch-closed, and this rollup issue is closed.
