 ### Task 1: DOM reader and legacy reader removal
 
 **Files:**
+
 - Create: `apps/chrome-extension/src/onetalk/main-page/card-observer/dom-card-reader.ts`
 - Delete: `apps/chrome-extension/src/onetalk/main-page/card-observer/react-card-reader.ts`
 - Modify: `apps/chrome-extension/src/onetalk/main-page/card-observer/entry.ts`
 - Test: `apps/chrome-extension/test/onetalk-rendered-card-reader.test.js`
 
 **Interfaces:**
+
 - Produces: `readOneTalkRenderedCardFromDom(pageWindow, card): OneTalkRenderedCardObservation | null`.
 - Consumes: `readConversationSelection`, `normalizeOneTalkProductUrl`, rendered-card validators and fingerprint creator.
 
 - [ ] **Step 1: Replace Fiber fixtures with DOM fixtures and red tests.**

 ### Task 2: Remove Fiber-only base evidence from local boundaries
 
 **Files:**

 ### Task 3: Remove approved server audit columns without data cleanup

 - Same content stays duplicate; different content increments `conflictCount` and returns conflict without overwriting JSON.
