Context

The reason why I raise this as a "Discussion" question is that I'm not sure if this is the intended behavior and worth opening an issue for it. So please let me know if this is an issue, I'll convert to it immediately.

Problem Definition

a3p tests for f:fast-usdc currently check that agoricNames.instance has a property called fastUsdc. In the current version of master (a66f6a1408016746f4f480241f3d6efa53732841) start-fast-usdc.js core eval fails so fastUsdc does not end up in agoricNames.instance.

I have noticed that this behavior goes unnoticed when yarn test -m fast-usdc is run. I also noticed that in the CI as well. Here's a recent CI run that passed however f:fast-usdc/test.sh fails.

Same thing in #10609 => https://github.com/Agoric/agoric-sdk/actions/runs/12225957386/job/34100576932?pr=10609#step:10:178

When set -ueo pipefail added on top of test.sh, yarn test -m fast-usdc fails.

Next Steps

Please let me know if this is intended or deserves an issue. @dckc @turadg @Chris-Hibbert
