From 6f57d60a8133ad5c2ef9edee0e14a61f89ebd2cd Mon Sep 17 00:00:00 2001 From: Claude Date: Fri, 19 Jun 2026 10:47:15 +0000 Subject: [PATCH 1/3] refactor(012): foundational consolidation (Phase 2) Wave-1 zero-behavior-change dedup that later slices build on: - Add INSTRUCTOR_SHOW_ANSWERS_KEY constant; replace the 'qd/instructor/showAnswers' magic string across quiz-table, qd-instructor, session, bootstrap, event-coordinator (T003) - Add utils/page-id.ts getPageIdFromUrl(); replace the inline pathname->filename->strip-.html parses in bootstrap (x2) and event-coordinator, with unit tests (T004/T005) - Add clearBadges(link) helper in home-badges; replace 3 duplicated badge-stripping loops (T006) - Add createEmptyStudentRecord(session) in storage-service; replace the two duplicated new-record literals in loadStudentRecord (T007) - Extract spinnerStyles into components/shared-styles.ts and adopt in qd-migration-dialog (T008; divergent error/button styles left intact to preserve exact rendering per the behavior-preservation rule) DoD: typecheck, lint, 791 unit + 67 integration tests, format, build, size-check (36.95KB gzip) all green.

Adds characterization + XSS-regression integration tests (T012/T013/T020). - Extract enhancers/instructor-answer-reveal.ts as the single shared, security-sensitive answer-reveal path; bootstrap (initial-load, adds qd-quiz-instructor class) and event-coordinator (post-login) now both call it. Behavior preserved exactly via an addInstructorClass option. Adds characterization tests (T014/T019). Export QuizTableMetadata type for the shared enhancer.
