  `breaking-changes` `bug-fix` `description-fix` `guide-changes`

  BREAKING: create\_bulk\_user\_import switched from `request` to `upload_file` — the CSV must now be base64-encoded on send; create\_high\_five now requires `creator_id` (provider rejects requests without it); list\_check\_ins.order\_by enum narrowed to exclude provider values `id` and `report` (both trigger 502). Non-breaking: marked People Attributes and Objectives write actions (create\_people\_attribute, create\_people\_attribute\_value, create\_objective, create\_key\_result) plus their read counterparts as `releaseStage: preview` (workspace feature-flag / plan-tier gated on trial tenants); list\_high\_fives multi-value filters now use `arrayFormat: repeat` for correct serialization; group\_types name\_plural must end in "s" — provider silently rewrites otherwise (now documented in the field description, no more server-side value mutation on our end); documented update\_user check-in cadence enums (reporting\_period, biweekly\_due\_day\_which\_week, monthly\_due\_day\_which\_in\_month) with UI-verified meanings and co-required-field preconditions; added feature/plan-tier enablement guide to the authentication section (Reviews, Objectives, People Attributes).
