separate the law that binds from the discipline that is shown
For an Eastern Catholic church these are sharply different questions and the library was collapsing them. Ruthenian particular law binds on four kinds of day in the year; the tradition those parishes actually keep is the Byzantine fast entire. Reporting only the law made a week of the Great Fast read as 'no meat, fish, eggs or dairy' seven times over, which is the legal floor and not the fast. --typikon shows the day at the Typikon's discipline while the obligation still comes from the jurisdiction's own law, because that is the part only it can say. The Ruthenian rule now answers 'what binds here' separately from 'how is this day kept', which is what makes the two composable at all. Three tests hold the seam: exactly the same days bind whichever discipline is displayed, the binding minimum is never stricter than the level shown, and the flag is a no-op for a jurisdiction already on the Typikon.

### The law and the fast are not the same question

For an Eastern Catholic church the two come apart sharply, and reporting only

what binds; it is not what is kept.

the same three days starred. Nothing about the obligation changes.

It is a no-op for a jurisdiction already reckoning by the Typikon.
