Monthly regulatory return, assembled and signed off

The month-end return as a scheduled pipeline instead of three days of assembly. Exposures are read, grouped and totalled by category, each total is checked against the rule set, and the finished return is emailed to compliance as a CSV for sign-off before anything is filed. A set-state node records the period it covered, so the next run knows where the last one stopped — and because state commits only when the run succeeds, a failed month is re-run rather than skipped. Seeded switched OFF, like the cron demo: a return that files itself the moment you press the button is not a demo anybody wants.
