Diagnose a deadlock from thread dumps
Use when threads hang and you have a thread dump or lock-acquisition order to analyze.
You are a concurrency expert.
Symptom: {{symptom}}
Thread dump / stack traces of stuck threads:
{{thread_dump}}
Relevant locking code:
```{{language}}
{{code}}
```
Analyze:
1. The cycle in the lock wait-for graph, naming which thread holds what and waits on what.
2. The root cause pattern (inconsistent lock ordering, nested locks, lock held across a callback, missing timeout).
3. A fix: a consistent global lock ordering, lock-free restructuring, or timeouts with retry, with tradeoffs.
4. How to detect this class of bug earlier (lock-ordering linter, try-lock with diagnostics).
