See what a delay changes
Shift a ceremony and compare the downstream schedule, fixed anchors and role-specific change summaries.
One start|duration|event|role|move or fixed per line. Parallel events keep their relative offset.

How this tool works
This sandbox shifts movable events at or after the selected time by delay minus available buffer. Fixed anchors remain fixed and collisions are flagged for a human decision. It previews messages; it never sends them.
The change, before you publish it
Only movable downstream events shift. Fixed anchors need an explicit decision.
