-# 13 · requirements · flat · unfixable vulns (should pass)

-**Package manager**: `requirements`
-**Source layout**: flat
-**Expected outcome**: PASS — vulnerabilities exist but have no fix versions; `pip_audit_block_on: fixable` should not block
-
-## What this tests
-- `pip_audit_block_on: fixable` only blocks when fix versions are available
-- Unfixable vulnerabilities are reported but don't fail the workflow
