What they do
- Agent Arena shows independent proposals, a challenge, revisions, and a judge's selection through a coordinator-owned board.
- It exports the selected candidate and the transcript so the choice can be inspected.
- Rig-wall displays throughput, draft acceptance, GPU measurements, and queue information when configured sources provide them.
- It records normalized snapshots and replays saved sessions without starting live collectors.
- It shows missing values and stale connections explicitly.
What was measured
The supplied Arena runs demonstrate fixture behavior. Rig-wall's included session contains 40 synthetic frames. Neither is a measurement of model quality, GPU speed, or live endpoint compatibility.
What I learned
Synthetic fixtures help test an interface, but live measurements need their own validation. Explicit missing values and saved event sequences make debugging easier.
Status
11 October 2026: local projects with MIT licences. They have no configured Git remotes; publishing and live validation remain separate decisions.
