From 6021c26d664c0a3d405da99de950f428a23eda34 Mon Sep 17 00:00:00 2001 From: Claude Date: Fri, 19 Jun 2026 11:18:28 +0000 Subject: [PATCH 01/18] refactor(012): extract AuthService + route config reads (US2) Consolidate the duplicated ~100-line student-login flow from qd-login's handleStudentLogin and retryLoginAfterMigration into a shared AuthService (loginStudent / retryAfterMigration) returning a discriminated LoginResult. The component now only handles validation, session creation, events, and UI. Route DOM config reads (title selector, db name) through dom-config-reader helpers instead of inline document.getElementById calls in qd-login and qd-pin-reset-dialog. Adds characterization tests for the login outcomes (T015).
