shiftUnfinishedDescendantDates

Mutation

Shift visible, unfinished dated descendants at every depth using REST calendar semantics. Parent-project weekends determine the offset; each descendant's weekends and holidays adjust its dates. The parent deadline is not written directly; normal date synchronization may recalculate ancestors. Inaccessible descendants stay untouched; locked dates follow existing edit policy. Requires date-edit permission on the parent in workspaceId. Dates must be midnight UTC. This is a non-idempotent write; dry runs simulate it. Returns only readable descendants.

Returns [Action !]!.
