A prior runbook/workflow modelling experiment on this pack was reverted (it mixed prescriptive
Layer-3 knowledge into the observed-state pool and was partly fabricated). It still exists in commit
2096014 "add snapshots" in the sift-tech repo if you need to see what was tried. Do not
reintroduce it; the pool is observed-state only.
