Lessons

PROJECT CHECKPOINT

Turn git and github into evidence

Move the tracker through a feature branch, review and release tag.

  • Write acceptance criteria for working tree before implementation.
  • Keep the change small enough that a reviewer can connect it to the intended behavior.
  • Use the most direct check available for index and save the result.
  • Record one decision you would keep and one you would revisit after feedback.
