Confidence Score: 5/5

Safe to merge based on focused runtime coverage of both corrected failure paths.

The executed before-and-after checks exercised oversized positive and negative cookie expiration values and a cookie-processing exception after response receipt. The updated behavior matched the intended handling, and all focused regression tests passed.

Files Needing Attention: No further files need attention; the exercised changes are in aiohttp/cookiejar.py, aiohttp/client.py, and their focused regression tests.

T-Rex Logs

What T-Rex did

• Ran the CookieJar and in-process client harnesses against the previous and updated implementations, then ran the focused cookiejar and client-functional pytest selections.
• Observed that the previous implementation raised OverflowError when handling a 309-digit positive Max-Age and retained one acquired connection after the cookie-jar exception.
• Applied the changes to clamp positive Max-Age to CookieJar.MAX_TIME, immediately expire negative Max-Age, report zero acquired connections after the exception, and allow the follow-up request to complete.
• Executed the focused regression selections and confirmed all six tests passed, validating the corrected cookie expiration and response cleanup behavior.
• Cross-validated the changes against the targeted code areas and reviewed the accompanying artifacts to verify the before-and-after overflow handling and cleanup behavior.
