The warden openbao-platform-admin-login lane runs one silent child per login,
fails closed on any output and self-revokes; the old runbook printed output
and rolled back from a standing session that cannot exist.
- scripts/openbao-platform-admin-aal2.sh (+ .py): prepare (backup + assurance
claim mapping), apply (gated on this login's assurance_level=aal2, readback
of bound_claims), verify, rollback from the backup receipt via a fresh lane
login, rollback-body for the docs/openbao.md break-glass path. 0600 O_EXCL
receipts, value-free; no stdout/stderr.
- Role declaration maps /assurance/level to token metadata assurance_level.
- tests/test_openbao_platform_admin_aal2.py: fake bao end-to-end.
