Let me explain with concrete examples why the nested try-catch is essential:\n\nThe Problem Without Nested Try-Catch\n\nScenario: Keystore decrypts successfully, but certificate analysis fails.\n\nWithout inner try-catch:\ntry {\n  const { cert, privateKey } = await decryptKeyStore(...)  // ✅ SUCCESS\n  TiConnectRepository.settings = { cert, privateKey, ... }  // ✅ SUCCESS\n  \n  // No inner try-catch here\n  const certificateInfo = await CertificateAnalyzer.analyzeCertificate(cert)  // ❌ THROWS ERROR\n  \n  ipcManager.sendToAll(..., { success: true })  // ❌ NEVER REACHED\n} catch (error) {\n  // This catches the certificate analysis error\n  ipcManager.sendToAll(..., { success: false })  // ❌ WRONG! Reports failure even though keystore worked\n}\n\nResult: User sees \"Keystore decryption failed\" even though their keystore was successfully decrypted! 🐛\n\nWith Nested Try-Catch (Current Code)\n\ntry {\n  const { cert, privateKey } = await decryptKeyStore(...)  // ✅ SUCCESS\n  TiConnectRepository.settings = { cert, privateKey, ... }  // ✅ SUCCESS\n  \n  // Inner try-catch isolates certificate analysis\n  try {\n    const certificateInfo = await CertificateAnalyzer.analyzeCertificate(cert)  // ❌ THROWS ERROR\n    tiConnectEventObservability.send({ certificateType: ... })\n  } catch (error) {\n    // Handle certificate analysis failure gracefully\n    tiConnectEventObservability.send({ error: true, ... })  // ✅ Track error for monitoring\n  }\n  // Execution continues here!\n  \n  ipcManager.sendToAll(..., { success: true })  // ✅ CORRECT! Keystore decryption succeeded\n} catch (error) {\n  // Only catches keystore decryption errors\n  ipcManager.sendToAll(..., { success: false })  // ✅ CORRECT! Reports actual failure\n}\n\nResult: User sees \"Success\" because the keystore was decrypted. Certificate tracking failure is logged for monitoring but doesn't affect the user. ✅\n\nVisual Flow Diagram\n\n┌─────────────────────────────────────────────────┐\n│ Outer Try-Catch (Critical Operations)          │\n├─────────────────────────────────────────────────┤\n│ 1. Read keystore file        → If fails: FAIL  │\n│ 2. Decrypt keystore          → If fails: FAIL  │\n│ 3.

Or nothing.\n\nReply with ONLY the suggestion, no quotes or explanation.\n\nTurn 1 — Assistant\n\ncommit the changes",
