What Changed

• Added a new pull request template (.github/pull_request_template.md) that enforces structured PR descriptions with four required sections
• Removed deprecated Sweep AI configuration file (.github/sweep.yaml) and consolidated AI agent guidance into a single location
• Deleted two governance documentation files (ci-validation.md and governance-documents.md) from tech-conventions, streamlining documentation structure
• Updated all remaining tech-conventions markdown files with line-level formatting corrections (659+ lines across mage-x.md, 277+ lines in github-workflows.md, and similar changes across dependency-management.md, pull-request-guidelines.md, release-versioning.md, and security-practices.md)
• Added new AI compliance documentation (ai-compliance.md) to formalize AI agent interaction standards
• Normalized line endings and formatting across .cursorrules, .github/.env.base, and AGENTS.md files
• Reformatted GitHub workflow files (codeql-analysis.yml and scorecard.yml) with consistent YAML structure

Why It Was Necessary

• Consolidating PR structure requirements into a template ensures all contributors (human and AI) follow consistent documentation standards
• Removing outdated AI tooling configuration (Sweep AI) reduces maintenance burden and prevents conflicting agent instructions
• Streamlining governance documentation by removing redundant files improves discoverability and reduces documentation drift
• Standardizing line endings and formatting across configuration files ensures consistent behavior across different development environments and CI/CD systems
• Adding dedicated AI compliance documentation provides clear boundaries and expectations for automated contributions

Testing Performed

• Validated YAML syntax for all modified workflow files (codeql-analysis.yml, scorecard.yml) to ensure no parsing errors
• Verified pull request template renders correctly in GitHub's PR interface with proper markdown formatting
• Confirmed all markdown documentation files maintain valid structure and internal links remain functional
• Checked that removed files (sweep.yaml, ci-validation.md, governance-documents.md) are not referenced elsewhere in the repository
• Validated that .cursorrules and .github/.env.base maintain valid syntax after formatting changes

Impact / Risk

• Low Risk: Changes are primarily documentation and configuration formatting updates with no code logic modifications
• Breaking Change: None - removal of Sweep AI configuration only affects that specific tool, which appears to be deprecated
• Documentation Impact: Contributors must now use the structured PR template, improving consistency but requiring adherence to the four-section format
• CI/CD Impact: Workflow file reformatting maintains functional equivalence with improved readability
• Migration Required: None - existing workflows and processes continue to function without modification
