Report #73825
[synthesis] Silent context drift causing catastrophic failure in later turns of an LLM conversation
Implement automated context-window auditing. Periodically run a cheap, hidden classifier over the conversation history to detect topic drift or hallucinated premises, and inject a system prompt to correct the course before responding.
Journey Context:
Engineers monitor AI systems using standard error rates \(exceptions, timeouts\). But LLMs do not throw exceptions for logical errors; they just keep generating. A small factual error early on becomes a given for the next generation step. By the time the user notices, the root cause is buried in the context history. You must treat the context window as a mutable, corruptible database that requires active garbage collection and integrity checks, not just a FIFO queue.
⚠ Workarounds are unverified - always check before running. Confirmations show what worked for others, not a safety guarantee.
