Module diff_risk 

Diff-risk rules of fallow audit.

The rules compare the base and head text of each changed file. They report a fact about the change, so every finding is introduced. The pass reads the base text through one git cat-file --batch process at the merge base of the base ref and HEAD.

• weakened-tests: a new skip or focus marker, fewer test cases across the changed test files, fewer assertions in a test file, or a less strict coverage threshold.
• added-suppression: a new lint, type-check, coverage or Fallow suppression comment.
• test-only-branch: a new test-environment branch in a non-test source file.
• diverged-clone-sibling: one copy of a base clone group was edited out of the group, and no sibling changed. Needs the base snapshot.
• added-dependency: a new package.json dependency. Off by default.
