From 4125d7a4e1f18f0153dfb6e720242ebce0b14738 Mon Sep 17 00:00:00 2001 From: Hermes Date: Sat, 22 Aug 2026 18:54:57 -0700 Subject: [PATCH] =?UTF-8?q?[glm-grade=3DB]=20fix(auth):=20mount=20/auth/me?= =?UTF-8?q?=20on=20single-user=20installs=20=E2=80=94=20kill=20the=2060s?= =?UTF-8?q?=20404=20log=20storm=20(DC-093)?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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.
