Here's your breakpoint investigation guide:\n\nBrowser Breakpoint Investigation Guide\n\nSetup (Chrome DevTools on Staging)\n\n1. Open staging: https://pro-staging.doctolib.de/document_imports\n2. Open DevTools: F12 or Cmd+Option+I\n3. Go to Sources tab\n4. Disable cache: Settings (⚙️) → Disable cache\n5. Preserve log: Network tab → ✓ Preserve log\n\n---\n\nCritical Breakpoints to Set\n\nBreakpoint 1: Upload Completes (Frontend)\n\nFile: Press Cmd+P → type DocumentImportContext.tsx\n\nLocation: Line 396 (right after setDocuments)\n\n395:          return result\n396:        })\n397:        void invalidateUnclassifiedDocuments()  // ← SET BREAKPOINT HERE\n\nWhat to inspect when breakpoint hits:\n// In Console tab (while paused):\nuploadedDocument.id           // Document UUID\nDate.now()                    // Timestamp (record this)\nisFeatureEnabled('upload_document_write')  // Verify feature switch\n\n---\n\nBreakpoint 2: Cache Invalidation Function\n\nFile: Cmd+P → type unclassifiedDocuments.ts\n\nLocation: Line 128 (inside useInvalidateUnclassifiedDocumentsIndex)\n\n125: export const useInvalidateUnclassifiedDocumentsIndex = () => {\n126:   const queryClient = useQueryClient()\n127:\n128:   return () => queryClient.invalidateQueries({ queryKey })  // ← BREAKPOINT HERE\n129: }\n\nWhat to inspect:\nqueryKey                      // Should be ['unclassified_documents']\nqueryClient.getQueryCache()   // See current cache state\n\n---\n\nBreakpoint 3: Query Execution Starts\n\nFile: unclassifiedDocuments.ts\n\nLocation: Line 44 (GET request starts)\n\n41:   return useQuery({\n42:     queryKey,\n43:     queryFn: async ({ signal }) => {\n44:       const { status, bodyData } = await httpClient.get<...>(  // ← BREAKPOINT HERE\n45:         '/doctor_app/unclassified_documents',\n\nWhat to inspect:\nDate.now()                    // Timestamp (compare to upload timestamp)\nsignal.aborted                // Check if request was cancelled\n\n---\n\nBreakpoint 4: Query Results Received\n\nFile: unclassifiedDocuments.ts\n\nLocation: Line 51 (after GET completes)\n\n49:       )\n50:\n51:       if (Array.isArray(bodyData)) {  // ← BREAKPOINT HERE\n52:         try {\n\nWhat to inspect:\nbodyData.length               // How many documents returned?\nbodyData.map(d => d.id)      // List of document IDs\nbodyData.find(d => d.id === 'YOUR_UPLOADED_DOC_ID')  // Is new doc here?\nstatus                        // HTTP status code\n\n---\n\nInvestigation Workflow\n\nTest 1: V2 Upload (Feature Switch ON)\n\n1. Set all 4 breakpoints\n2. Upload a document\n3. When Breakpoint 1 hits (upload complete):\n      // Console:\n   let docId = uploadedDocument.id\n   let uploadTime = Date.now()\n   console.log('Uploaded:', docId, 'at', uploadTime)\n   // Resume (F8)\n\n4. When Breakpoint 2 hits (invalidation):\n      // Console:\n   console.log('Invalidating at', Date.now())\n   console.log('Gap:', Date.now() - uploadTime, 'ms')\n   // Resume (F8)\n\n5. When Breakpoint 3 hits (query starts):\n      // Console:\n   let fetchTime = Date.now()\n   console.log('Fetching at', fetchTime)\n   console.log('Gap from upload:', fetchTime - uploadTime, 'ms')\n   // Resume (F8)\n\n6. When Breakpoint 4 hits (results):\n      // Console:\n   console.log('Got', bodyData.length, 'documents')\n   let found = bodyData.find(d => d.id === docId)\n   console.log('New doc found?', !!found)\n   \n   // CRITICAL: If NOT found, check these:\n   bodyData.map(d => d.id)     // List all IDs\n\n7. If document NOT found:\n   - Note the timestamp\n   - Click \"dokumente anzeigen\" again\n   - Breakpoint 4 will hit again\n   - Check if document appears now\n\n---\n\nTest 2: V1 Upload (Feature Switch OFF)\n\nDisable feature switch, then repeat Test 1 with same breakpoints.\n\nCompare:\n- Upload → Fetch time gap (V1 vs V2)\n- Document found on first attempt? (V1 vs V2)\n\n---\n\nNetwork Tab Analysis (Parallel Investigation)\n\nWhile using breakpoints, also watch Network tab:\n\nKey Requests to Monitor:\n\nPOST Request (Upload):\nPOST /doctor_app/v2/documents  (V2)\nPOST /doctor_app/documents     (V1)\n\nCheck:\n- Status: 200\n- Time: ___ms\n- Response body contains: document.id\n\nGET Request (List):\nGET /doctor_app/unclassified_documents\n\nCheck:\n- Status: 200\n- Time: ___ms\n- Response body: array of documents\n- Contains your new document? YES/NO\n- Timing tab: TTFB (Time To First Byte)\n\nCritical Timing Analysis:\n\nIn Network tab Timing panel for the GET request:\n- Queueing: Connection pool wait?\n- Stalled: Waiting for available connection?\n- Waiting (TTFB): Server processing time\n- Content Download: Response transfer time\n\n---\n\nWhat Each Scenario Tells You\n\nScenario A: Fast V2, Slow V1\nV2: Upload→Fetch gap: 50ms   → Doc NOT found → Replication lag\nV1: Upload→Fetch gap: 300ms  → Doc found     → More time for replication\n\nRoot Cause: V2 is faster, queries before replica catches up\n\n---\n\nScenario B: Both Use Same Timing\nV2: Upload→Fetch gap: 100ms → Doc NOT found\nV1: Upload→Fetch gap: 100ms → Doc found\n\nRoot Cause: Something different in V1/V2 backend (not timing)\n\n---\n\nScenario C: Network Shows Connection Reuse\nNetwork tab shows:\n- Upload uses Connection ID: 123\n- Fetch uses Connection ID: 124 (different!)\n\nRoot Cause: Connection pooling - different connection can't see write\n\n---\n\nQuick Investigation Commands (Console)\n\nWhile paused at any breakpoint:\n\n// Check feature switch\nisFeatureEnabled('upload_document_write')\n\n// Check React Query cache\nwindow.__REACT_QUERY_DEVTOOLS_CACHE__\n\n// Force read cache\nqueryClient.getQueryData(['unclassified_documents'])\n\n// Check timing\nperformance.now()  // Current time in milliseconds\n\n// Network timing\nperformance.getEntriesByType('resource')\n  .filter(r => r.name.includes('unclassified_documents'))\n\n---\n\nInvestigation Checklist\n\n- [ ] V2 Upload→Fetch gap measured: _____ ms\n- [ ] V1 Upload→Fetch gap measured: _____ ms\n- [ ] V2 first attempt finds document: YES / NO\n- [ ] V1 first attempt finds document: YES / NO\n- [ ] V2 second attempt finds document: YES / NO\n- [ ] Network shows different connection IDs: YES / NO\n- [ ] GET request TTFB time: _____ ms\n\n---\n\nAfter gathering this data, you'll know:\n1. Is V2 faster than V1? → Explains timing race\n2. Do both fail equally? → Rules out timing, points to V2 backend bug\n3. Does 2nd attempt always work? → Confirms it's a timing issue\n\nWant me to help analyze the results once you've run this investigation?\n\nTurn 1 — User\n\n[SUGGESTION MODE: Suggest what the user might naturally type next into Claude Code.]\n\nFIRST: Look at the user's recent messages and original request.\n\nYour job is to predict what THEY would type - not what you think they should do.\n\nTHE TEST: Would they think \"I was just about to type that\"?\n\nEXAMPLES:\nUser asked \"fix the bug and run tests\", bug is fixed → \"run the tests\"\nAfter code written → \"try it out\"\nClaude offers options → suggest the one the user would likely pick, based on conversation\nClaude asks to continue → \"yes\" or \"go ahead\"\nTask complete, obvious follow-up → \"commit this\" or \"push it\"\nAfter error or misunderstanding → silence (let them assess/correct)\n\nBe specific: \"run the tests\" beats \"continue\".\n\nNEVER SUGGEST:\n- Evaluative (\"looks good\", \"thanks\")\n- Questions (\"what about...?\")\n- Claude-voice (\"Let me...\", \"I'll...\", \"Here's...\")\n- New ideas they didn't ask about\n- Multiple sentences\n\nStay silent if the next step isn't obvious from what the user said.\n\nFormat: 2-12 words, match the user's style. Or nothing.\n\nReply with ONLY the suggestion, no quotes or explanation.",
