The classic 'podman images | grep -q' pattern races under set -o pipefail: grep exits on its first match, podman dies SIGPIPE (141) writing the remaining RepoDigests lines, and pipefail promotes 141 to the pipeline status — the gate reads 'no match' and refuses to deploy (2026-09-30, dankserver). Same bug in the serve script (it would restart-loop the same way). Fix: capture podman's output into a variable first, grep the variable. Patched in the R9V September deploys by luck of timing.
