• Production API

What-if projection of apply_hospitality_action_publish_federated_output — previews the action (execute-and-roll-back) and folds its would-be events into rollup deltas, returning the contribution an apply would make to the daily_rooms fact (ADR / RevPAR / TRevPAR / Occupancy inputs) without persisting anything. Requires the same actions:hospitality.action.publish_federated_output:apply scope as apply. An action that emits no rooms-fact events yields an empty daily_rooms.

Request Body^required

Media typeapplication/json

object

branch

Apply against an open branch’s overlay view instead of the canonical (main) plane. The action’s writes land in the branch’s copy-on-first-write overlay, its events in the branch’s own stream, and the invocation is journaled for merge-by-replay. Branch writes are action-only, so this is the write-side entry point to a branch (POST /v1/branches forks one).
