A real agent change to a public repository, rerun on its exact commit.
Where it runs
-
Every claim in an agent's pull request gets a verdict before anyone reviews it.

-
A release waits until the claims it depends on have really run.

-
The claims behind a release are rerun as soon as it ships.

-
The same claim by claim check for the payments, records and filings agents complete.
