• Production API

Scenario preview of apply_hospitality_action_recommend_sell_limit — runs the action exactly as apply would (validation, handler dispatch, modified-object projection, commit-time cross-link validation) then rolls the transaction back. Returns the modified_objects / modified_links / warnings the apply would have produced without persisting anything or firing any outward effect. Requires the same actions:hospitality.action.recommend_sell_limit:apply scope as apply. No Idempotency-Key.

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).

string format: uuid

params

required

object

cadence

Run cadence (used only when opening a fresh run)

string

Allowed values: nightly intraday hourly event_triggered manual

confidence

required

Confidence ordinal

string

Allowed values: low medium high

Calibrated probability (optional)

string format: decimal

expires_at

Recommendation expiry (default: issued_at + 4h when absent)

string format: date-time

expires_on

The house business day the recommendation lapses after, in place of `expires_at`: the house's open business date decides expiry, not the wall clock, so a day's recommendations apply on that business day however late it closes

string format: date

factors_considered

required

Signals that drove the recommendation

Array<string>

Allowed values: pickup_pace booking_curve competitive_set event_calendar historical_pattern segment_mix channel_mix length_of_stay_distribution cancellation_rate no_show_rate package_attachment group_displacement weather other

required

Forecast snapshot (struct as JSON; `forecast_kind` and `as_of` required)
