Rename the rule “Guesses {M}” to “Guesses {I}” and reword its text as follows:

Each Participant may have a single Guess, or may have no Guess, and defaults to having no Guess. Guesses are publicly tracked mutable game variables. A non-Mastermind Participant may set their Guess to any single word as a Daily Action. A Mastermind may set their Guess to any other Participant’s Guess as a Daily Action.

If the outcome of a successful Heist Action would change any word in the ruletext that matches a Mastermind’s Guess, then instead of changing that word in the ruletext, that Heist Action does not change that word in the ruletext.
