Why

The admin dashboard's People register (Overview, Admins, Teams) is empty in production because nothing tells the backend who holds which role here. Roles are hand-made in this dashboard, so People needs a way to read them and to change them without becoming a way around this IdP's delegation rules.

What

• Binding a role to People. Master Admin binds a hand-made role on its page, in the new People register card. A role can be bound as admin, team:<key>:member or team:<key>:lead.

  • The binding is stored in role.people_binding (migration 0023), with a check constraint.
  • Managed roles can't be bound.
  • Roles carrying any idp:* permission can't be bound, whether directly, through a parent or through an implication.
  • Saving a role or permission that would give a bound role such a permission is refused.

• GET /api/internal/people-roles (backend client, idp:access:read) lists the bound roles, everyone holding them by hand, and everyone with a PoliNetwork Microsoft 365 login: name, directory email, Microsoft 365 object ID, Telegram ID and username.

  • Unlike the access snapshot, it includes roles that grant no permission, such as a plain team membership.
  • The Microsoft 365 object ID lets People match Soci group members to linked accounts without relying on an address.

• POST /api/internal/people-roles (backend client, new internal scope idp:people:roles) applies one People command { id, actor, sub, reason, changes } on behalf of the dashboard user the backend authenticated. Each change is a desired state: { kind: "admin", active } or { kind: "team", team, role: "member" | "lead" | null }.

  • This IdP plans the concrete assignments against its own role graph and applies all of them or none.
  • It refuses with 409, instead of reporting a change that didn't happen, when the mapping is ambiguous or when the requested state would still be held through another role.
  • The backend only names the actor. This IdP resolves the actor's own access and checks every assignment before any write. It refuses unless all of these hold:
    • The role is bound.
    • The actor isn't giving themselves a role. Giving one up is allowed.
    • For admin and team member roles, the actor has admin:access + people:write, or leads that team.
    • For Lead roles, including a Lead role inherited by the role being changed, the actor has admin:access + people:appoint.
    • Bounded delegation: unless Master Admin, the actor holds every permission the role grants.
  • These rules mean an HR member can't make themselves, or anyone else, HR Lead, even through a member role that wraps a Lead role.
  • Each assignment is audited as role.assign/role.unassign with via: "people", the reason and the command ID. The command itself is stored as a people.roles receipt: repeating an ID, for example after a lost response, applies nothing again and returns the current roles; repeating it with a different command is refused with 409.
  • The answer is the person's bound roles after the command.

• MCP: Master Admin gets set_role_people_binding, so an agent connected to /api/mcp can do the whole setup (create_permission, create_role, set_role_people_binding, assign_role). Role tools already return peopleBinding.

Deploying

Deploy before the backend PR: the POST contract changed and the backend expects the new one.

1. Migrate (0023).
2. Bind the roles on their pages:
   • existing roles: admin, trusted-admin, it-core → team:it:member, it-lead → team:it:lead;
   • new roles: Lead/Member HR, Design & Marketing, Events & Partnerships.
3. Grant idp:people:roles to the backend client on its application page. Reads work without it.

Pairs with the backend PR that consumes these endpoints.

Testing

• vp check, unit tests (people-binding.test.ts, including the command planner), vp build.
• people-roles.integration.test.ts against Postgres (PEOPLE_ROLES_TEST_DATABASE_URL): a command applies once and its replay writes nothing; a reused ID with different input is refused; a command with one refused assignment writes none; a revocation kept by an unbound parent role is refused with 409.
• Against a throwaway Postgres with the migrations applied:
  • binding by a non-Master Admin was refused;
  • a malformed binding was refused;
  • adding idp:roles:write to a bound role was refused;
  • self-grant, an HR member appointing a Lead, and a volunteer granting admin were all refused;
  • a Lead adding and removing their own team's member was allowed;
  • audit rows carried via: people;
  • the directory listed holders with Telegram.

Walkthrough

The change adds People bindings for eligible hand-made roles, authorization rules for assigning and unassigning those roles, and an internal backend API for reading People directory data and changing role assignments. It also adds role-page controls, database constraints, auditing, and API documentation.

Changes

People role management

Layer / File(s)	Summary
Binding contract and authorization rules src/auth/rbac.ts, src/auth/people-binding.ts, src/auth/people-binding.test.ts, src/db/rbac.ts, drizzle/0023_role_people_binding.sql, drizzle/meta/*, related RBAC test fixtures	Roles now include a nullable People binding. Binding formats, role eligibility, and assignment authorization rules are defined and tested. The database schema, migration, and snapshot metadata include the binding field and its constraints.
Binding updates and role-page controls src/auth/rbac-store.ts, src/auth/rbac.functions.ts, src/auth/mcp-server.ts, src/components/rbac/people-binding-card.tsx, src/routes/access/roles/$roleId.tsx, README.md	RBAC saves validate existing bindings. Master Admin can set or clear a role binding through the role page or MCP tool. The role page displays binding details and controls for eligible roles.
Directory reads and audited role changes src/auth/people-role-command.ts, src/auth/people-roles.ts, src/auth/people-binding.test.ts, src/auth/people-roles.integration.test.ts	The People directory includes eligible bound roles and their holders. Role-change commands are planned against role inheritance, authorized before writes, and audited. Command receipts support replay of matching command IDs and reject reuse with different input.
Scoped backend API and documentation src/auth/oidc-clients.ts, src/auth/access-snapshot-token.ts, src/auth/index.ts, src/routes/api/internal/people-roles.ts, src/routeTree.gen.ts, README.md	The internal scope list includes idp:people:roles, and service-token validation accepts the required internal scope. The backend route exposes directory reads and role changes with scoped authorization. The README documents the endpoints and authorization requirements.

⚠️ Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.

Require a non-blank reason.

The PR states that each change is audited with a reason. However, z.string().trim().max(500) accepts "" and whitespace-only input. A role change can then be audited with an empty reason. Add .min(1) after .trim() so the 400 path rejects a missing reason.

Based on learnings: an admin user-management API with an audit policy should require a non-blank "reason" field with a max length and validate it.

🛡️ Proposed fix

-  reason: z.string().trim().max(500),
+  reason: z.string().trim().min(1).max(500),

Review comments at @src/auth/people-roles.ts:
- Line 124: In changePeopleRole, validate that input.actorId exists before
calling refreshIdentityMembership; if it is unknown, throw the existing
RbacError with status 403 so the route handles it as a forbidden request.
- Around line 162-179: In the people-role assignment flow, detect whether the
`user_role` insert or delete actually changed a row by using `.returning()` and
checking the result. If no row changed, skip the audit insert and return a
distinct unchanged/conflict result; preserve the existing audit behavior when a
row changes.
