The migration hook Job gets CURRENT_VERSION once, at render time, and a failed pod is retried with that same environment. Each migration that finished has stamped the cozystack-version ConfigMap by then, yet the retry started from the rendered version and ran those migrations again. Migrations are written to run once, so a re-run is not safe in general. The runner now starts from the version stamped in the ConfigMap. A failed read aborts the pod, since falling back would bring the re-run back and the Job retries anyway. The rendered value is kept only when the ConfigMap holds no integer version, which is also the case where the chart could not derive a real one from it. An all-digit stamp past the shell's integer range aborts too: its comparison fails inside an if, out of reach of set -e, and the Job would go green having run nothing, while the chart renders that stamp as 0.
