Checks 1–7

Could you clarify what you mean by **“descryption soon JP”**? * Is this a **job description (JD)**? * Does **JP** mean *Japan*, *Japanese language*, or something else? * What is the description for (product, company, event, social media post, etc.)? Share a bit more detail and I’ll create it right away 👍

Everything above is one sweep, pinned to one block. This asks the same checker to run the same ladder against this agent right now — one request to its declared document, at the current head. The answer belongs to no run, is stored nowhere, and never enters a published rate or finding.
