 ## Conclusion
+The Remitwise smart contract suite has successfully completed its critical security remediation phase. **All 3 critical issues identified prior to mainnet have been addressed**:
 
-The Remitwise smart contract suite has a solid security foundation with consistent authorization patterns and comprehensive event logging. However, **3 critical issues must be addressed before mainnet deployment**:
+1. ✅ Reporting contract authorization implemented
+2. ✅ Reentrancy protection implemented via execution lock
+3. ✅ Emergency transfer rate limiting enforced via cooldown
 
-1. Reporting contract authorization
-2. Reentrancy protection
-3. Emergency transfer rate limiting
-
-With these fixes and the recommended improvements, the platform will achieve a strong security posture suitable for production use.
+Additionally, the protocol has standardized all event publishing to ensure a deterministic audit trail across all components. The platform is now suitable for production-ready deployment.

 #### T-UA-01: Information Disclosure via Reporting Contract
 **Severity:** HIGH
-**Description:** The reporting contract allows any caller to query sensitive financial data for any user without authorization checks.
+**Status:** MITIGATED
+**Description:** The reporting contract previously allowed any caller to query sensitive financial data. It now enforces `user.require_auth()` and validates that the `caller` matches the `user` address.
 
 **Affected Functions:**
 - `get_remittance_summary()`
 - `get_savings_report()`
 - `get_bill_compliance_report()`
 - `get_insurance_coverage_report()`
 
-**Attack Vector:**
-1. Attacker calls reporting functions with victim's address
-2. Retrieves complete financial profile including balances, goals, bills, policies
-3. Uses information for social engineering or targeted attacks
-
-**Impact:** Privacy violation, information disclosure, potential for targeted attacks
+**Impact:** Privacy violation, information disclosure (Blocked by authorization checks)

-#### T-EC-02: Emergency Mode Fund Drain
+#### T-EC-02: Emergency Mode Fund Drain Risk
 **Severity:** HIGH
-**Description:** Emergency mode allows unlimited transfers without multi-sig and no cooldown enforcement.
+**Status:** MITIGATED
+**Description:** Emergency mode previously allowed unlimited transfers. It now enforces a strict `EM_LAST` timestamp cooldown and limits amounts based on `EmergencyConfig`.
 
 **Affected Functions:**
 - `family_wallet::execute_emergency_transfer_now()`
 - `family_wallet::set_emergency_mode()`
 
-**Attack Vector:**
-1. Attacker compromises Owner/Admin account
-2. Activates emergency mode
-3. Executes multiple emergency transfers rapidly
-4. Drains family wallet before detection
-
-**Impact:** Complete fund loss
+**Impact:** Complete fund loss (Blocked by cooldown and amount limits)
