+# CI/CD Fix Validation
+
+This file validates that the multi-line PR body fix is working correctly.
+
+## Issue Fixed
+
+**Problem**: The `pr-into-dev.yml` workflow was failing with exit code 127 when checking for linked issues because the PR body variable was not properly quoted, causing bash to interpret multi-line content as commands.
+
+**Solution**: Changed from storing PR body in a variable to writing it to a temporary file using heredoc (`<< 'EOF'`), which safely handles multi-line content with special characters.
+
+## Test Validation
+
+✅ **Fix Committed**: Multi-line PR body handling implemented
+✅ **Branches Updated**: Fix applied to main, dev, and feature branches
+✅ **New Test PR**: This PR validates the fix works correctly
+
+## Expected Results
+
+When this PR is created targeting `dev`:
+
+1. **Validate PR Structure** job should:
+   - ✅ Pass fork safety check
+   - ✅ Validate branch name (feature/test-ci-fix-validation)
+   - ✅ Validate PR title (Conventional Commits format)
+   - ✅ Check for linked issues (should pass without exit code 127)
+
+2. **Quality Gates** job should:
+   - ✅ Run Python validation (skip if no .py changes)
+   - ✅ Run Markdown linting (this file should validate)
+   - ✅ Run secret scanning (should pass)
+
+3. **PR Summary** job should:
+   - ✅ Generate summary of all checks
+   - ✅ Show all checks passed
+
+## Validation Criteria
+
+- [x] Feature branch created from dev
+- [ ] Committed with Conventional Commits format
+- [ ] Pushed to GitHub
+- [ ] PR created to dev
+- [ ] pr-into-dev.yml workflow triggered
+- [ ] All validation steps passed (including linked issues check)
+- [ ] Quality gates executed successfully
+- [ ] PR ready for merge (testing only, will close after validation)
+
+## Multi-line Content Test
+
+This PR body contains:
+- Markdown formatting
+- Special characters like `backticks`
+- Mentions of workflow files like pr-into-dev.yml
+- Checkboxes and lists
+- Code blocks
+
+All of this content should be handled correctly by the fixed workflow.
+
+## Cleanup
+
+After validation:
+- Close PR without merging (fix is already in dev/main)
+- Delete feature branch
+- Document successful validation
+
+---
+
+**Date**: 2025-11-12
+**Purpose**: Validate multi-line PR body fix in CI/CD workflows
+**Status**: Testing in progress
+**Related PR**: #3 (original test that revealed the issue)
