scripts/designbook-refresh.mjs chains the automatable steps
(check->pull->sync->ir->adapt-lit->parity) and stops for the human drift-triage
step, propagating the adapter-contract exit codes (3=stop for triage, 4=parity
fail). Gating steps call the node scripts directly so make doesn't collapse the
3/4 codes to 2. Best-effort steps (check/pull/sync) warn and continue; --no-pull
/--no-check/--no-parity flags. Documented the loop in stack-and-commands.md and a
step-6 drift-resolution runbook in designbook/README.md.
