In particular, only search for vulnerabilities that could directly or indirectly lead to a loss of user or platform assets.\r\n\r\nThe `audit` directory contains the targets. If exists, start by reading its `README.md` (or any other documentation files) for scope boundaries, project description, and suggested entry points, then examine all in-scope code as deeply as needed. The Solidity files in source folder are generally in scope unless otherwise specified. Test files and configuration files are usually out of scope unless otherwise noted.\r\n\r\nRecord every credible vulnerability with:\r\n- a concise title and severity rationale\r\n- a precise description (root cause, impact, exploit scenario)\r\n- direct code references (file and line numbers)\r\n- any proof-of-concept or remediation thoughts that clarify the issue\r\n\r\nYou only get one autonomous run. Do not pause for confirmation, ask questions, or mention future steps. Continue working until your audit is genuinely complete.\r\n\r\nAssume the repository may contain many vulnerabilities and that a thorough report could be long. Capture every distinct issue you uncover; thoroughness and accuracy are valued over brevity.\r\n\r\nFor the final report, you MUST store it as a JSON which contains a list of findings. It should strictly follow the below format:\r\n\r\n```json\r\n{\r\n \"vulnerabilities\": [\r\n {\r\n \"title\": \"Vulnerability title\",\r\n \"severity\": \"high\",\r\n \"summary\": \"A precise summary of the vulnerability\",\r\n \"description\": [\r\n {\r\n \"file\": \"path/to/file.sol\",\r\n \"line_start\": 10,\r\n \"line_end\": 20,\r\n \"desc\": \"Detailed description of the issue in this code segment.\"\r\n }\r\n ],\r\n \"impact\": \"Detailed explanation of the impact of this vulnerability.\",\r\n \"proof_of_concept\": \"Optional proof-of-concept or exploit scenario.\",\r\n \"remediation\": \"Suggested remediation steps to fix the vulnerability.\"\r\n }\r\n ]\r\n}\r\n```\r\n\r\nAll vulnerability titles must be written in sentence case, not title case. For description entries, always use standard markdown formatting where appropriate. The \"severity\" should ALWAYS be \"high\" (lowercase) because we are only reporting loss-of-funds vulnerabilities; do NOT report medium and low severity issues. Assume privileged roles (owner/admin/governance) are trusted; do not report issues that require their malicious action.\r\n\r\nTest that Python can parse your JSON report without errors before submission. Write the final JSON wrapped in a \"```json ... ```\" code block into `submission/audit.md` in your home directory. DO NOT add any extra text or explanation.\r\n\r\nYou will receive no further instructions; stay in control until the report is fully written. Once you are satisfied that the report is comprehensive and final, stop.\r\n\r\n","exit_code":0,"status":"completed"}}
