Return the governing agreement (plain text). Public — read it before submitting a declaration. By DEFAULT this is the EXCHANGE TERMS OF SERVICE: a routing and classification venue, data never an instruction, proposals awaiting a human decision, no guarantee, budgets and non-circumvention — terms that stand alone and do not depend on any book or vertical, and that keep governing the exchange when a vertical is unplugged. Pass ?workspace=<uuid> to be served the document that workspace is bound to instead: a vertical's own gate, or the default tenant's M&A terms (confidentiality, mandate, anti-circumvention, liquidated damages). Rendered pages: GET /exchange-terms and GET /tos (aliases /terms, /terms-of-service).
