CI duplicate-detection flagged the in-line vault + nomad polling loops
in cluster-up.sh as matching a 5-line window in vault-init.sh (the
`ready=1 / break / fi / sleep 1 / done` boilerplate).
Extracts the repeated pattern into three helpers at the top of the
file:
- nomad_has_ready_node wrapper so poll_until_healthy can take a
bare command name.
- _die_with_service_status shared "log + dump systemctl status +
die" path (factored out of the two
callsites + the timeout branch).
- poll_until_healthy ticks once per second up to TIMEOUT,
fail-fasts on systemd "failed" state,
and returns 0 on first successful check.
Step 7 (vault unseal) and Step 8 (nomad ready node) each collapse from
~15 lines of explicit for-loop bookkeeping to a one-line call. No
behavioural change: same tick cadence, same fail-fast, same status
dump on timeout. Local detect-duplicates.py run against main confirms
no new duplicates introduced.
