# List Supervision Sessions

> Sessions to supervise: every agent's for an admin, one's own otherwise.

Reads `sessions`/`events` directly instead of fanning out one ADK HTTP
call per agent. Two queries total, whatever the number of agents -- the
N+1 shape this codebase has paid for more than once.

        `preview` is the first thing the user asked — without it every row reads
        the same and the list cannot be scanned, which is what it looked like
        with 422 copies of one test harness in it.
