开放知识格式 v0.2：为 Agent 建立可信判断

Google just shipped Open Knowledge Format v0.2, and it is all about agentic trust. When a person writes a wiki page, you know who to ask if it is wrong. When an agent writes ten thousand pages overnight, nobody is accountable for any of them. The agent reading those pages needs signals it can check before it reads a single line. v0.2 puts four of them in the frontmatter: • sources: what the page was built from, with author and usage count. Raw signals, no trust score. • generated and verified: who wrote it, who checked it. Human checked and machine checked stay separate. • stale_after: a fixed date, so freshness is a date comparison. • status: draft, stable, or deprecated. The best part is a new type called Attested Computation. It holds the approved query for a metric. The agent fills in parameters and nothing else. It never writes the SQL. After a run, a small script compares what actually ran against what was approved. Rename a table or drop a join and it fails, and the number never gets shown. Still just markdown and YAML. Every new field is optional. Your v0.1 bundles still work. GitHub Repo: https://t.co/BlwunQhi7q
