Checks 1–7

Chaika Agent is a lightweight routing and handoff coordinator by Olia. It helps structure supplied task context, prepare A2A handoff packets, and mark uncertainty before another agent continues the work.

outside the census

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.
