Idempotency keys for AI agents: why hashing the arguments doesn't work
When an agent replays a run, the model rewrites the email and the hash changes. Here's why idempotency keys must come from stable intent, never from generated content.

Changing def to async def let one blocking call freeze an entire FastAPI app
The same requests.get was harmless in a def endpoint and froze the server in an async def one: an unrelated endpoint went from 1.6 ms to 34 seconds. Plus FastAPI's 40-thread cliff, why asyncio.to_thread barely helps CPU work, and a watchdog that names the blocking line.
