Merge Review - Version Maintenance Strategy Implementation

Summary

This PR implements a comprehensive version maintenance strategy for the ansible-bind9-role, closing issue #5. The changes establish clear policies for multi-version BIND9 support, improve documentation, and introduce tooling for grammar tracking and version comparison.

What's Excellent

✅ Version Support Documentation - The VERSION_SUPPORT.md provides clarity on:

• BIND9 version support matrix (9.18 LTS + 9.20+)
• OS platform compatibility (Debian/Ubuntu focus)
• Branching strategy with main/9.18 split
• Backporting policies for security, bugs, and features
• Clear deprecation process

✅ Professional Release Management

• Changelog follows "Keep a Changelog" format
• Semantic versioning scheme clearly defined
• Release types (security/feature/bugfix) categorized
• Upgrade notes included for users

✅ Grammar Tooling & Automation

• fetch_bind_grammar.py - Automated grammar fetching from Gitea/upstream
• compare_bind_versions.py - Breaking change detection
• process_mcp_result.py - MCP output handling
• Enables proactive identification of version differences

✅ Branch Strategy Implementation

• .bind9version marker provides clear branch identification
• Separate 9.18 branch for LTS-focused maintenance
• Cherry-picked documentation reduces duplication
• Clean separation of concerns (stable vs. development)

✅ CI/CD & Testing Improvements

• Gitea Actions workflow added
• Podman installation for container testing
• Molecule configuration updates
• Linting issues resolved (yamllint, ansible-lint)

✅ Code Quality

• 19 well-structured commits with clear messages
• Linting errors systematically fixed
• Comprehensive commit history shows iterative refinement
• Addresses edge cases (no-change detection, backup removal optimization)

Observations & Recommendations

⚠️ Enhancement Opportunities (Non-blocking)

1. Grammar Files - While the tooling is ready, the actual v9.18.44 and v9.20.18 grammar JSON files should be fetched and committed (mentioned in "Next Steps") to complete the version tracking infrastructure

2. CI/CD Matrix - The workflow is simplified and functional. Consider expanding the test matrix once the repository is established with multiple platforms

3. Feature/Bind9-20-Support - The feature branch for 9.20 is mentioned as "prepared" but may benefit from early template work to validate the versioning approach

Files & Scope

Core Documentation:

• ✅ docs/VERSION_SUPPORT.md - 400+ lines, comprehensive
• ✅ CHANGELOG.md - Well-structured
• ✅ README.md - Updated with compatibility matrix

Tooling:

• ✅ scripts/fetch_bind_grammar.py - Production-ready
• ✅ scripts/compare_bind_versions.py - Functional
• ✅ bind9-grammar/upstream/README.md - Clear instructions

Configuration:

• ✅ .bind9version - Branch marker
• ✅ Molecule & CI/CD configurations - Updated
• ✅ 26 files changed with +3682 -63 modifications

Compliance & Standards

✅ Follows Ansible Creator AGENTS.md practices
✅ Professional documentation standards
✅ Semantic versioning approach
✅ Clear branching strategy following git best practices

Readiness Assessment

Ready to Merge: YES

This PR successfully establishes the foundational infrastructure for long-term version maintenance of the BIND9 role. The documentation, tooling, and branch structure are solid and well-conceived. The only outstanding items are operational (fetching grammar files) rather than code/structural issues.

Post-Merge Action Items

1. Fetch v9.18.44 and v9.20.18 grammar files using the new tooling
2. Run comparison to generate breaking change documentation
3. Expand CI/CD test matrix for multi-platform coverage
4. Begin feature/bind9-20-support branch with BIND9 9.20 specific templates
5. Tag release v1.0.0 after grammar files are in place

---

Assessment: High-quality implementation of a complex versioning strategy. Recommended for merge.
