⚠️ Experimental endpoint — not yet a stable contract. This resource ships as experimental / beta. While experimental, its schema and behaviour may change without a version bump — including breaking changes within v1.0 itself. Anyone consuming it does so for evaluation only, or by coordinating adoption with their account manager so changes can be sequenced with them. It graduates to a stable, version-locked contract (where the normal breaking-change rules apply) only when this experimental notice is removed.

Set or change the reason of an exit entry. Only the new reason is checked: it must apply to the entry's subject (users, partner invites, or partners and the partner's category). When the entry had no reason, the exit type set by the rule that ended the relationship is kept as ruleExitType. The token's admin and the time are recorded.
