## Statements (checkable)
0. CPU time per HTTP request is 10 ms on Workers Free and 5 min (default 30 s) on Workers Paid; Cron Triggers get 10 ms on Free.  [✓0 ✗0]
1. Waiting on fetch(), KV reads or database queries does not count toward CPU time.  [✓0 ✗0]
2. When a Worker exceeds its CPU time limit Cloudflare returns Error 1102 with the message "Worker exceeded resource limits"; analytics show outcome exceededCpu.  [✓0 ✗0]

## Fix
```text
Move heavy parsing out of the request path (precompute, cache, or split across Cron runs), or upgrade to Workers Paid and raise limits.cpu_ms.
```

## Error signatures
- substring: `Worker exceeded resource limits` (Error 1102 message (documented))
