The engine on every node's PATH was the one a person copied at installation, a build behind every delivery; and the way out of issue 339 was a terminal act at the machine, which ADR 0272 and the operator's rule of the same day make impossible to type. The record, located in the engine, the controller and the catalogue's check, with the fixes' pull requests; ADR 0272 gains the rule as a dated insight: the operator types one command, nox, and every text addressed to the operator names a nox line. words.py now refuses a daemon's line, with --list lines for the catalogue's copy; the lifecycle and the operator's-machine designs and issue 343's quotations are reworded.
