The frontend admin panel polls GET /api/v1/auth/me on every dashboard
load and every 60s per open tab. /me lived only in the DC-048 admin
router, mounted only when email auth is enabled — so every single-user
install (the default) answered 404 and logged a DC-404 ERROR + stack
once per minute per open tab. Verified live in production logs.
- routes/auth/index.js: /auth/me now ALWAYS mounted. Multi-user +
req.user returns the stored profile (mode:'multi'); otherwise the
legacy single-operator response (role:'admin', isAdmin:true,
legacy:true, mode:'single'). Session-gated — NOT added to
PUBLIC_ROUTES, so unauthenticated polls get a clean 401.
- Frontend behavior unchanged: attachTrigger requires me.user.role
=== 'admin', and user stays null in single-user mode, so no Admin
button appears on single-user installs.
- openapi.yaml /api/v1/auth/me (200/401) now matches reality.
- +6 tests (route present both modes, response shapes, PUBLIC_ROUTES
absence, DC-048 admin-mount invariant, HTTP-level dispatch reach).
Judge: GLM-5.3 cold read, grade B ship (verdict URN recorded in
STATE.md); polish note (HTTP-level mount-order test) folded in same
commit. Full suite 115 suites / 2687 tests green.
