feat(authz): admin role-assignment API for configured custom roles (#4063 gap 2) (#6382)

* feat(authz): admin role-assignment API for configured custom roles (#4063 gap 2)

The RBAC provider accepts arbitrary configured role names (guest, ...),
but nothing could assign them to real users: User.system_role was pinned
to Literal["admin", "user"] at the API layer while the DB column stayed
a plain String(16) for exactly this future, and zhfeng's #3462 audit
listed the missing assignment surface as gap 2 — custom roles were
declarable in YAML but unreachable for authenticated web users.

- User/UserResponse.system_role widens to a non-empty string; whether a
  role is *assignable* is the admin API's contract, not the model's.
- RbacAuthorizationProvider exposes known_roles; the Gateway's new
  assignable_role_names() unions the built-ins with the provider's
  configured role names (custom providers: built-ins only).
- New admin-only router /api/v1/admin/users: GET lists users with their
  role; PATCH assigns — role validated against assignable names (an
  unknown role would silently fall through to default_role on every
  decision), 404 for missing users, and the last remaining admin cannot
  be demoted (bootstrap lockout protection). Enforcement is unchanged:
  the assignment only changes which role the principal carries; the
  @require_permission route guards and runtime provider decisions remain
  the single enforcement points.
- SQLite repository gains list_users (ordered oldest-first).

Tests: router guard/422/404/409/no-op/happy-path, last-admin invariant
(both directions), assignable names union, principal carries the
configured role; the two old Literal-rejection contract tests updated to
the new contract (custom role representable; empty string still
rejected).

* fix(auth): widen the frontend user schema for custom roles (review-lessons catch)

The role-assignment API's review-lessons sweep found the one consumer
class the implementation had not enumerated: the FRONTEND parses /me
with a strict userSchema whose system_role was z.enum(["admin",
"user"]) — a user assigned a provider-configured custom role (guest)
would fail userSchema.parse in server.ts and break the auth flow before
rendering anything.

- types.ts: system_role widens to z.string().min(1), kept in lockstep
  with the backend model (min_length=1). All existing consumers compare
  === "admin", so any other value is simply non-admin — no behavior
  change for admin/user.
- server.test.ts: contract tests — custom role parses verbatim; empty
  string still rejected.
- config.example.yaml: the authorization comment now says custom roles
  become reachable via PATCH /api/v1/admin/users/{id} and that a
  declared-but-unassigned role grants nothing.

* fix(auth): commit the admin_users router, drop the stale type-ignore, document the surface

Review catch on #6382: the router module was never staged — app.py and
the tests import it, so the pushed branch could not boot (ImportError in
create_app). The local tree kept it as an untracked file, which is why
every check passed before the push.

- Actually commit app/gateway/routers/admin_users.py.
- _row_to_user: drop the now-stale '# type: ignore[arg-type]' on
  system_role — the model field is a plain string now (keep the comma).
- README: the authorization paragraph now mentions the admin
  role-assignment surface (GET/PATCH /api/v1/admin/users, admin-only,
  last-admin demotion protected, declared-but-unassigned grants nothing).
- server.test.ts import-order lint fix from the frontend sweep.

* fix(auth): field-scoped role writes close the demotion-undo race

Review round 2 on #6382 — three findings, one design:

- [P1] update_user copied system_role from the caller's account snapshot,
  so a password change that read the user as admin could restore a role
  concurrently revoked by the demotion route (stale-snapshot write-back).
  Account writes are now field-scoped against each other: update_user is
  the credential/profile writer (never touches the role, mirrors the
  row's current role back), update_system_role is the only role writer
  (single-column, never touches credentials or token_version).
- The last-admin lockout check moved inside the role write's serialized
  transaction: count-then-write across two sessions let two concurrent
  demotions of the only two admins both pass. Same idiom as
  create_first_admin — BEGIN IMMEDIATE on SQLite, pg_advisory_xact_lock
  on a distinct key on Postgres, raise on unknown dialects.
- UserNotFoundError from the racing-delete window maps to the route's
  404 instead of a 500.

Tests 11->12: real-repo regression covering the P1 interleaving
(demotion lands -> stale credential snapshot writes -> role stays
revoked, credentials applied), field isolation both directions, and the
last-admin invariant raised from inside the write with the row intact.
Mutation-verified: restoring the role write-back in update_user fails
it.

* style(auth): format the server auth tests

* fix(tests): migrate the personal-MCP demote revocation to update_system_role

The role-write field-scoping (66e2cec23) made update_user a
credential/profile-only writer, so the demote branch of
test_revocation_blocks_discovery... silently no-oped and CI failed on
all four shards (assert 2 == 1 — the role never changed).

- The demote now goes through update_system_role, the sole role writer.
- The fixture gains a second admin: the revocation test demotes its sole
  synthetic admin, which the new last-admin lockout guard correctly
  blocks — a second admin keeps the scenario legal without weakening
  either invariant.

Advanced deployments can enable pluggable authorization with `authorization.enabled` in `config.yaml`. A configured `AuthorizationProvider` filters denied tools before they reach the model or deferred-tool catalog, then the same provider is checked again before every business-tool execution through the existing guardrail middleware. Gateway `threads:*` and `runs:*` route permissions are derived from the same provider, while existing owner checks and admin-only management gates remain in force. Every HTTP route that starts or enables a future Agent run requires `runs:create`: this includes the stateless `POST /api/runs/stream` and `POST /api/runs/wait` endpoints plus scheduled-task create, update, resume, and manual-trigger mutations. Scheduled-task mutations retain their existing `threads:write` requirement, and the stateless routes separately enforce ownership when the optional thread ID is supplied in the request body. A generated `tool_search` may bypass the second tool check only when it fronts the current build's already-filtered deferred catalog. Model access follows the same provider: the Gateway `models` list is filtered per principal, `model:use` is enforced on model detail requests and again when the runtime resolves the agent's model, and a denied default model falls back to the first remaining candidate that also passes `model:use`. The built-in RBAC provider supports per-role `tools`, `routes`, `models`, `skills`, and `sandbox` allow/deny policies and validates that `default_role` names a configured role; authorization is disabled by default. See `config.example.yaml` and the [authorization RFC](docs/plans/2026-07-10-pluggable-authorization-rfc.md).

See `config.example.yaml` and the [authorization RFC](docs/plans/2026-07-10-pluggable-authorization-rfc.md).
Follow-up suggestions also check `model:use` before calling the selected model, including the default model when no name is supplied. A denied model returns HTTP 403 without an LLM call; authorization-provider failures follow the configured `fail_closed` policy.
