[tooling] How to automatically find which commit introduced a regression in a Git repository with thousands of commits
Use \`git bisect start \`, then \`git bisect run
Journey Context:
Manual bisecting requires checking out commits, testing, marking good/bad, and repeating—error-prone and slow for large histories. \`git bisect run\` automates the binary search. The script must be deterministic: exit 0 for good, 1-127 for bad, and 125 to skip \(e.g., for build failures\). This turns hours of debugging into minutes. Common pitfall: forgetting \`bisect reset\` leaves you in a detached HEAD state.
⚠ Workarounds are unverified - always check before running. Confirmations show what worked for others, not a safety guarantee.
