// ---------------------------------------------------------------------------// Self-host admin users API — the shared, provider-neutral `AdminUsersHandlers`// backed by a Better-Auth-authorized platform view, mounted at// `/api/admin/users*` beside the existing invite-code admin routes.//// AUTH: an owner/admin member of the single org, resolved by the shared// `requireInstanceAdmin` — the SAME gate the invite-code admin API uses// (`admin/handlers.ts`), not a new permission concept. Membership is resolved// against the INSTANCE's organization id, never the caller's// `session.activeOrganizationId`: see require-admin.ts for the privilege// escalation that distinction refuses. Self-host has no// organization-OWNED api key (Better Auth keys always belong to the user who// created one), so there is no machine-credential path here; the operator's own// admin session is the credential. That asymmetry with cloud is deliberate and// is why `AdminUsersProvider` is a seam rather than one shared implementation.//// The READ half is identical to cloud's: a subject-less, tenant-reach executor// from `makePlatformExecutor`, projected by the shared `admin/reads`. Self-host// is single-tenant, so the tenant is always the boot-seeded org. Identity// (email/name per row), the `?email=` resolver and the `?search=` match all// come from the shared `MemberDirectory` — here Better Auth's `member` + `user`// tables through its own adapter (`auth/member-directory.ts`), the SAME read// the MCP plane makes, so no plane keeps its own join.// --------------------------------------------------------------------------- import { HttpRouter } from "effect/unstable/http";import { Effect, Layer } from "effect"; import {  AdminUsersProvider,  DbProvider,  HostConfig,  MemberDirectory,  PluginsProvider,  adminUserDirectoryFromMembers,  getAdminUser,  listAdminUserConnections,  listAdminUsers,  listAdminUsersWithConnections,  makeAdminUsersApiLayer,  makePlatformExecutor,  platformViewOf,  requestScopedMiddleware,  type AdminUsersHeaders,} from "@executor-js/api/server";import {  AdminUserNotFound,  AdminUsersError,  AdminUsersForbidden,  AdminUsersUnauthorized,} from "@executor-js/api";import type { Executor } from "@executor-js/sdk"; import { BetterAuth, type BetterAuthHandle } from "../auth/better-auth";import { requireInstanceAdmin } from "./require-admin";import { SelfHostDb, SelfHostDbProvider, type SelfHostDbHandle } from "../db/self-host-db";import { SelfHostHostConfig, SelfHostPluginsProvider } from "../execution"; /** * The SAME gate the invite-code admin API applies — literally the same * function, not a second copy of the same idea, which is how the two planes * came to share a bypass.
