If “Hidden Agendas” passes, this could wind up matching an Agenda, but I suppose that’s a risk you might take in order to get a rule functioning as it originally had.

By “this”, I meant the Janitor‘s Daily Action.

I think the Janitor does nothing here, since mutable rules are not allowed to “directly amend or modify the ruleset or non-mutable dynastic gamestate through means other than defining or successfully performing a Heist Action” per The Vault.

Good catch. Would have to change “a word in a rule” to “a word in a Mutable rule” and “Daily Action” to “Heist Action”.
