-Because `createDailySchedule(datetime, message)` targets the day after `datetime`, running it at May 1 00:00 creates May 2 00:00 through May 3 00:00. This keeps the persona from "planning itself" in response to a slash command and makes the schedule feel like background life state.
+Because `createDailySchedule(datetime, message)` targets the day after `datetime`, running it at May 1 00:00 creates May 2 00:00 through May 3 00:00. `createMonthlySchedule(datetime, message)` follows the same next-day convention for its first monthly entry, so monthly automation should run on the last local midnight of the month; for example, May 31 00:00 creates a monthly window that begins June 1. This keeps the persona from "planning itself" in response to a slash command and makes the schedule feel like background life state.
