# memattr_survey — see defaults/main.yml for the question, README.md for how to run and
# read it, and infra/PROD-PROVISIONING.md §0b for the settled mechanism this measures.
#
# ORDER OF OPERATIONS
#   1. preflight.yml — refuse to touch a node that is not prod, not idle, or has no
#      persistent journal; read the resume point; record the boot we found it on.
#   2. round.yml x N — reboot, measure, append, mirror. Per-node fail-safe.
#   3. harvest.yml   — re-derive every retained boot from the journal (authoritative).
#
# The playbook splits these across plays so that preflight is any_errors_fatal (one unsafe
# node stops everything) while the rounds are not (one dead node stops only itself), and
# so that the controller-side analysis runs even if every node dies. This file is the
# whole-role entry point kept for completeness; the playbook calls the stages directly.
