I've added temporary debug logging. Now here's your investigation guide:\n\nInvestigation Guide for Staging\n\nStep 1: Deploy Debug Version\n\nBuild with debug logging\nnpm run build:dev\n\nDeploy to staging (your deployment process)\nThen enable feature switch if not already on\n\nStep 2: Test with Console Open\n\nChrome DevTools Setup:\n1. Open staging: https://pro-staging.doctolib.de/document_imports\n2. Open Console (F12 → Console tab)\n3. Filter by \"[DEBUG]\" to see only our logs\n4. Clear console\n\nTest Sequence:\n1. Upload a document\n2. Observe console logs - you should see:\n      [DEBUG] Upload completed at: 12345.67\n   [DEBUG] Document ID: abc-123-uuid\n   [DEBUG] Invalidating cache now...\n   [DEBUG] Fetching unclassified documents at: 12346.89\n   [DEBUG] Fetch completed. Document count: X\n   [DEBUG] Document IDs: [...]\n\n3. Check if your document ID is in the list\n4. If NOT, click \"dokumente anzeigen\" again\n5. Check console again\n\nStep 3: Analyze Timing Data\n\nRecord these metrics:\nUpload End Time: _______ ms\nFetch Start Time: _______ ms\nTime Gap: _______ ms (Fetch Start - Upload End)\n\nFirst Attempt:\n- Document in list? YES / NO\n- Document count: _______\n\nSecond Attempt (if needed):\n- Document in list? YES / NO  \n- Document count: _______\n- Time since upload: _______ ms\n\nStep 4: Compare V1 vs V2\n\nTest with feature switch OFF (V1):\n1. Disable upload_document_write feature switch\n2. Repeat test sequence\n3. Record same metrics\n\nExpected Findings:\n\nIf replication lag:\n- ✅ V1: Time gap > 500ms (slower, gives time for replication)\n- ❌ V2: Time gap < 100ms (faster, hits before replication)\n\nIf connection pooling:\n- Both should fail equally (same db1/db1_readers config)\n\nIf caching:\n- Different cache behavior between V1 and V2\n\nStep 5: Backend Investigation\n\nCheck if V2 transaction actually commits:\n\nAdd this to V2 controller (engines/documents/app/controllers/documents/doctor_app/v2/documents_controller.rb):\n\ndef create\n  # ... existing code ...\n  @document = create_document_via_service(file, tanker_encrypted_file)\n  \n  # TEMPORARY: Debug - verify document is actually persisted\n  Rails.logger.info(\"[DEBUG] Document created: #{@document.id}, persisted: #{@document.persisted?}\")\n  \n  # TEMPORARY: Try to find it immediately\n  found = Documents::Document.unscoped.find_by(id: @document.id)\n  Rails.logger.info(\"[DEBUG] Document findable: #{found.present?}\")\n  \n  handle_post_creation_response\n  render formats: :json\n  # ...\nend\n\nCheck staging logs after upload to see if document is findable immediately after creation.\n\nStep 6: Database Connection Check\n\nIn Rails console on staging:\n\nCheck if reads go to replicas\nActiveRecord::Base.connection.execute(\"SELECT pg_is_in_recovery();\")\n=> true = replica, false = primary\n\nCheck connection pool\nDocuments::Document.connection_pool.stat\nLook for checked_out connections\n\nVerify document exists on primary\nDocuments::Document.connection.execute(\"SELECT COUNT(*) FROM documents WHERE id = 'your-doc-id'\")\n\nExpected Outcome\n\nAfter this investigation, you should be able to answer:\n\n1. Is it replication lag?\n   - If time gap V1 > V2, and second attempt always works → YES\n   \n2. Is it connection pooling?\n   - If document is findable in Rails but not in query → Connection issue\n   \n3. Is it caching?\n   - If document appears in different tabs differently → Cache issue\n   \n4. Is it something else?\n   - If none of above, we need to dig deeper into V2 service implementation\n\nNext Steps After Investigation\n\nOnce you identify the root cause, we can implement the appropriate fix:\n\n- Replication lag → Force read from primary after write, or add smart delay\n- Connection pooling → Use Database.on_writer for post-write queries\n- Caching → Fix cache invalidation strategy\n- Transaction not committed → Fix V2 service to ensure synchronous commit\n\nWould you like me to help with any specific part of 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.\n\nTurn 1 — Assistant\n\ngit diff",
