After a checkpoint on real VMs surfaced several deployment-only bugs (pooled conns to restarted peers, shared-account file permissions, a tmux build whose capture-pane crashes the server, old log data drowning greps, an O(n^2) view on the event loop), I added a short 'found on the real cluster and fixed' list to the checkpoint section of the implementation plan, one line per issue with the test that guards it. I also wrote standing rules where later tasks will see them: the demo-script section now says to read console output from the pipe-pane mirror and never call capture-pane, and the experiment rules say to run the prep script first. Commit messages explain a fix, but the next person writing demo scripts reads the plan section for their task, not git log. If an operational constraint is not in that section, they will hit it again.
