[aw] Failure cascade detected

## ⚠️ Failure Cascade Detected

**11 `[aw] * failed` issues** were filed within the last **60 minutes** (since Wed, 16 Sep 2026 14:27:53 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 comparing the failures listed in issues #61363, #61364, #61366, #61367, #61369, #61370, #61371, #61372, #61373, and #61374. Check recent infrastructure changes, provider status, and lockfile drift; done means the common cause is resolved, cascade-suspected issues can be batch-closed, and this rollup issue is closed.
