GDPx real-workstation review: six engineering lessons from AI running 8 hours straight

把 AI 扔进真实工位连干 8 小时后，比跑分更管用的六个工程教训

SemiAnalysis's GDPx benchmark has models use vendor agent frameworks to solve 206 real business problems in up to 8 hours. The strongest model averages about 12%. The article draws six engineering lessons from the failures: build a document authority map, set an independent rollback gate, write deterministic measurement scripts, keep an external evidence ledger, check the eval environment, and route by total cost per task.

Why it matters: It turns long-horizon failures on GDPx into engineering practice, folding document authority tagging, independent rollback checks and an external evidence ledger into agent workflows.
