Draw a contract approval flowchart with Mermaid flowchart TD syntax. The owner drafts the contract and the department manager reviews it; if not approved it goes back. Legal then reviews the terms, and requested changes send it back to the drafter. With no changes, finance reviews the payment terms. If the value is above the threshold, executive approval is needed. Then prepare for signature, both parties sign, file and log the contract, and perform and pay per the contract. Use diamonds for decisions and no parentheses in node text. Output only the mermaid code block.
