Execute
Continue what another began and keep every decision they made; no starting over.

Try it on your work
Take an unfinished thing someone else made, with their blessing, and continue it in its own direction, not yours: their logic, their standards, as best you can read them, for one full session. Where you couldn't tell their intention from your preference is the finding.
Continue someone else's written or spoken line of thought for three paragraphs or three minutes, as them: their vocabulary, their moves. Show them; the places they say "I wouldn't say that" are a map of what makes their thinking theirs.
Adopt a plan you didn't write and execute its next stage without amending it, improvements noted separately rather than applied. The urge-to-amend log is the real output; the stage itself was the excuse.
How it has been used
Take up and continue what another began: the second author finishing the novel, the apprentice completing the master's panel, LeWitt's drawings made by other hands. The move forbids starting over: you inherit the decisions already made and work forward from them, including the ones you'd never have made.
