runner/harness/warmsnap.py: raw per-volume tar of an app's stack volumes while UNDEPLOYED, under /var/lib/ci-warm/<recipe>/ (meta.json + volumes/<vol>.tar); one last-good, atomic dir swap; restore clears+untars each volume back. Asserts undeployed (consistency). Reused by WC1.1 (pre-upgrade keycloak snapshot) + WC5. +5 unit tests (48 unit pass). LIVE round-trip PROVEN on warm keycloak: create marker realm -> undeploy -> snapshot (mariadb+providers vols) -> deploy -> delete marker (mutate DB) -> undeploy -> restore -> deploy -> marker realm BACK; keycloak healthy.

"""Unit tests for the WC3 snapshot helper's pure path/meta logic (runner/harness/warmsnap.py).
|
|
|
|
The docker/tar snapshot+restore round-trip is integration (proven live on cc-ci against a real
|
|
keycloak volume, W0.5). Here we cover the layout, meta read, and the has_snapshot completeness check.
