What Makes a Handover Useful Without Freezing the Past?

A handover should help the next person act—not leave them guessing, or bind them to a rule that no longer fits.

For a recurring task, what belongs in the written record: the steps, the reason behind them, the exceptions, or a person to ask? And how should a team mark guidance that needs reviewing when the work changes?

I’m interested in the smallest handover that gives someone enough context to make a sound decision—and then lets them own the work.
