fix(coderd): enforce required external auth on workspace create (#26314) - #26791
Merged
Conversation
Required external auth (`optional = false`) was only enforced by client-side preflight checks, so creating a workspace via the REST API succeeded even when the owner had never authenticated, producing a broken workspace. `createWorkspace` now validates the workspace owner's external auth server-side and returns 403 before any row is inserted or prebuild is claimed. The owner (not the initiator) is checked because build-time token injection uses their links, so this also covers admin-on-behalf-of creates and prebuild claims. Use `optional = true` to allow pre-provisioning for unauthenticated users. Fixes PLAT-241. > This PR was generated by Coder Agents on behalf of @dylanhuff-at-coder.
