^[A-Za-z_][A-Za-z0-9_]*$Query Parameters
Billing wallet for this request: an organization you belong to, by id (team_…) or by name as GET /orgs lists it (case-insensitive), or personal. Omitted, the account's active wallet applies (PATCH /orgs/active; personal until set). Two organizations sharing the name answer 409 ambiguous_org and need the id. Sandboxes and snapshots stay creator-private. On /environments routes, only this query parameter selects the organization's shared environments; the X-Boat-Org header and the active wallet do not apply there. Members read them, owners and admins change them.
Body
Response
New version minted.
Result of a granular environment change. Every change mints a new immutable version holding just that delta; existing sandboxes stay pinned until upgraded.
