System Documentation

What problem does it solve?

Bisects Lean toolchain versions to pinpoint regression-causing commits or nightly changes in behaviour, enabling rapid isolation of regressions.

Core Features & Use Cases

  • Automated regression discovery: Use lean-bisect to compare endpoints across toolchain ranges and identify the exact commit that changed behaviour.
  • Flexible workflow: Supports self-contained test files, #guard_msgs, and flags like --ignore-messages, --nightly-only, and --timeout to tailor the search.
  • Operator handoffs and reporting: Guides users to produce a Zettelkasten note or upstream report via @lean-zettelkasten / @lean-pr.

Quick Start

Run the lean-bisect script on a minimal test file to locate the regression between two toolchain versions.
