+    │ · with traces
+    │ | Test: Successful Transaction Signing
+    │ | Total number of signatories in the multisig
+    │ | 4
+    │ | Required threshold of signatures
+    │ | 3
+    │ | Number of signatories actually signing this transaction
+    │ | 3
+    │ | Total amount in the contract (in lovelace)
+    │ | 100000000000
+    │ | Maximum spending limit per transaction (in lovelace)
+    │ | 1000000000
+    │ | Amount being withdrawn in this transaction (in lovelace)
+    │ | 1000000000
+    │ | Remaining amount in the contract after withdrawal (in lovelace)
+    │ | 99000000000
+    │ | Result: Transaction successfully signed and executed!
+    ┕━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 1 tests | 1 passed | 0 failed
+```
+
+This test validates the contract's ability to execute transactions when properly
+authorized. It demonstrates a successful transaction where:
+
+- 3 out of 4 signatories approved the transaction (meeting the threshold)
+- The withdrawal amount (1,000,000,000) was within the spending limit
+- The contract balance was correctly updated after the transaction
+
+The test confirms that the contract correctly processes transactions when the
+required number of signatories (3 out of 4) approve and the withdrawal amount is
+within the specified limit.
+
+#### B. Test Case: Rejected Insufficient Signatures (reject_insufficient_signatures)
+
+```

+    │ | Result: Signature threshold successfully updated!
+    ┕━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 1 tests | 1 passed | 0 failed
+
+      Summary 1 check, 0 errors, 0 warnings
+```
+
+This test verifies the contract's ability to adjust the signer threshold from 2
+to 3 without errors, demonstrating the flexibility of the contract's security
+parameters.
+
+### Threshold Adjustment Workflow
+
+1. **Initiate Threshold Change:** Users can propose new threshold values through
+   an intuitive interface.
+2. **Review Proposed Changes:** The system clearly presents current and proposed
+   thresholds for easy comparison.
+3. **Collect Required Signatures:**Authorized signers can efficiently review and
+   sign the proposal.
+4. **Confirmation of Update:** Upon collecting required signatures, the system
+   promptly updates the threshold.
+
+This streamlined process ensures that threshold adjustments are both secure and
+user-friendly.
+
+### User Feedback
+
+> "The process of adjusting the signer threshold was intuitive and
+> straightforward. The clear visuals helped us understand the proposed changes,
+> and the signature collection process felt secure." - John Doe, Contract
+> Administrator

+
+    ┍━ multisig ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
+    │ PASS [mem: 596818, cpu: 258625029] success_add_signer
+    │ · with traces
+    │ | Test: Successfully Adding a New Signer to the Multisig Contract
+    │ | Number of signatories before addition
+    │ | 4
+    │ | Current contract value (in lovelace)
+    │ | 100000000000
+    │ | Current signature threshold
+    │ | 3
+    │ | Number of signatories approving this change
+    │ | 4
+    │ | Redeemer used for this operation
+    │ | 122([])
+    │ | Number of signatories after addition
+    │ | 5
+    │ | Signature threshold after addition (unchanged)
+    │ | 3
+    │ | Contract value after adding signer (should be unchanged)
+    │ | 100000000000
+    │ | Result: New signer successfully added to the multisig!
+    ┕━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 1 tests | 1 passed | 0 failed
+```
+
+This test confirms the contract's ability to dynamically add a new signer,
+increasing the total number of signatories from 4 to 5.
+
+### Dynamic Signer Addition Process
+
+1. **Proposal Initiation**: An authorized user proposes a new signer, providing
+   necessary credentials.
+2. **Collective Review**: Existing signers examine the proposal details.
+3. **Approval Gathering**: The system collects required signatures for the
+   addition.

+    │ | 100000000000
+    │ | Number of signatories before removal
+    │ | 4
+    │ | Signature threshold before removal
+    │ | 3
+    │ | Number of signatories approving this change
+    │ | 4
+    │ | Redeemer used for this operation
+    │ | 122([])
+    │ | Number of signatories after removal
+    │ | 3
+    │ | Signature threshold after removal and adjustment (Can be changed)
+    │ | 2
+    │ | Contract value after removing signer (should be unchanged)
+    │ | 100000000000
+    │ | Result: Signer successfully removed and threshold adjusted
+    ┕━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 1 tests | 1 passed | 0 failed
+```
+
+This test verifies the contract's capability to remove signers and automatically
+adjust the threshold, demonstrating its adaptability to changing organizational
+needs while maintaining security.
+
+### Dynamic Signer Removal Process
+
+1. **Removal Proposal**: An authorized user initiates the removal of a specific
+   signer.
+2. **Proposal Review**: Remaining signers assess the removal proposal.
+3. **Consensus Building**: The system gathers necessary approvals, excluding the
+   signer in question.
+4. **Execution and Confirmation**: Post-approval, the signer is removed, and the
+   system displays the updated list for verification.
+
+### Security Considerations
+
+- The contract maintains a minimum signer threshold to prevent security
+  vulnerabilities.
+- Threshold adjustments may be required before certain signer removals to
+  maintain contract integrity.
+
+## Conclusion
+
+The Upgradable Multisignature Smart Contract demonstrates robust security,
+flexibility, and user-centric design. Through comprehensive testing and
+thoughtful process implementation, it effectively manages secure asset spending,
+allows for seamless threshold adjustments, and facilitates dynamic signer
+management.
+
+These features collectively ensure that the contract can adapt to evolving
+organizational needs while maintaining the highest standards of security and
+usability.
