Every existing check asks whether a box answers. None asked whether it answers with the code you shipped. The 2026-08-08 stale deploy was invisible to all of them: lith, the CDN, the oven and session-server were each green while the mirror session-server fetches from sat nineteen commits behind knot with a commit of its own on top. Read-only and offline-tolerant — it asks both remotes for their tip, and when this clone holds both commits it says how far apart they are. Replayed against that day's shas it reads: DIVERGED, mirror has 1 commit knot lacks and is 19 behind.
