Build against one authority model
headless.bid separates product access from auction authority. The Platform manages people, Workspaces and Environments; Ledgero Engine remains authoritative for Lots, commands, delivery and evidence.

Stable principles
- One Platform Environment maps to one opaque Engine Tenant.
- Browser sessions never receive Ledgero service credentials or OAuth refresh tokens.
- Platform roles never imply bidder or auction-operator authority.
- Auction records and evidence remain independently verifiable outside the hosted UI.
