2026-08-13 — Abstract playbooks (PlayTime)

Wrote the Scriptbook / PlayTime / CentrMark split and Host Awareness model so one playbook can name an intent (cli.install) and run on every OS. The Equivalence Engine stays a catalog (format and runtime are columns). PlayTime learns the host from a baked probe cascade, then binds. Humans stay at the intent layer; when the world changes, only the bottom catalog row moves.
