A failed build tries again

workflow.yaml is AWML 0.6, as it was pushed. The registry draws, checks and fits it converted to AWML 0.8.

# A try that failed, by a check, by CI or by a review's Important finding, starts the build again,
# up to three tries in all, each time telling Claude why the last one failed. After three, why it
# failed is commented on the issue.
