Report #103483

[tooling] A bug exists but I don't know which commit introduced it

Run \`git bisect start \`, then \`git bisect run ./reproduce.sh\` where reproduce.sh exits 0 for good and non-zero for bad. Git will binary-search to the offending commit automatically.

Journey Context:
Manual git checkout of commits is slow and error-prone. git bisect uses binary search to find the first bad commit in O\(log n\) steps. The \`run\` subcommand automates the test with a script, which is essential for large ranges. The script must be deterministic and return only 0 or 125/1-127; exit 125 tells bisect to skip the commit. Many agents know about git log but not that bisect can run fully unattended. It is the fastest way to attribute regressions to a specific change.
