The web view edits all three on a saved gift through Edit gift details. The SKY API gift PATCH accepts none of them, and a PATCH that includes gift_splits returns 200 and changes nothing. Any organization that assigns portfolio credit after gift entry (reassigned partners, recoded appeals, departed staff) falls back on Database view global changes, which retire in 2027. Please add PATCH for saved gifts to Gift v2, covering fundraiser_credits, soft_credits and gift_splits, with the validation the web view already applies.
