[Epic] Migrate VCS functionality to BMVCS module for v6

[joyshmitz]

🎯 Goal

Migrate VCS-agnostic functionality from legacy PRs to new v6 modular architecture as BMVCS module.

📚 Background

• Legacy PRs feat(core): Add VCS discovery mechanism #582, feat(templates): Add VCS adaptation templates #583, docs: Add VCS-agnostic documentation and examples #584 targeted old architecture
• v6 architecture uses modular system: src/modules/{bmm,bmb,cis,bmvcs}/
• Successfully migrated to feat/bmvcs-dev branch
• Ready for testing and submission

🎁 What is BMVCS?

BMVCS (BMad Version Control Suite) - module that adapts BMAD to team's version control workflow:

• ✅ Detects VCS type (Git, SVN, Perforce, no-VCS)
• ✅ Adapts documentation to team's workflow (GitHub Flow, GitFlow, Trunk-Based, etc)
• ✅ Optional module - install only if needed
• ✅ Integrates with BMM agents (architect, pm, dev)

---

✅ Migration Status: COMPLETE

✅ Completed Work

• Legacy PRs feat(core): Add VCS discovery mechanism #582, feat(templates): Add VCS adaptation templates #583, docs: Add VCS-agnostic documentation and examples #584 closed (migrated to v6)
• Module structure created in src/modules/bmvcs/
• VCS discovery and adaptation tasks
• 5 VCS workflow templates
• Complete documentation
• Examples and reference implementations
• Installer configuration
• VCS Adapter agent
• Setup workflow
• Development approach analysis

🚀 Next Steps

Phase 1: Testing (Current) ⏳

Following NEXT_SESSION.md priorities:

High Priority (Must Do)

• Test VCS discovery flow with real Git repositories
• Test VCS Adapter agent commands (*discover, *adapt-doc, etc)
• Test adaptation templates
• Test module installer
• Validate documentation links and examples
• Test BMM integration (optional dependency)

Medium Priority (Should Do)

• Test setup-vcs workflow end-to-end
• Test error handling and edge cases
• Verify graceful degradation when BMVCS not installed

Phase 2: Submission 📤

• Push feat/bmvcs-dev to fork/origin
• Decide on PR strategy (single vs multiple PRs)
• Create PR(s) to next branch
• Address review feedback

---

📋 PR Strategy Options

Option A: Single PR (~2,700 lines)

Pros: Complete feature in one PR, easier to review context
Cons: Exceeds 800 line guideline (needs justification)

Option B: Split into 3 PRs

1. Foundation + Core (~1,000 lines): Structure, tasks, agent
2. Templates + Docs (~1,000 lines): Templates, documentation
3. Examples + Integration (~700 lines): Examples, BMM integration

Pros: Follows CONTRIBUTING.md guidelines
Cons: More overhead, need sequential merging

Option C: Wait for maintainer feedback

Submit as single PR with explanation, let maintainers decide

---

🎯 Success Criteria

• All testing tasks from NEXT_SESSION.md completed
• Module installs and runs without errors
• Core workflows functional (discovery, adaptation, validation)
• Documentation complete and accurate
• PR(s) created and submitted to next branch
• Review feedback addressed
• BMVCS module merged into v6

---

📝 Notes

• Module follows v6 conventions (bmm, bmb, cis pattern)
• All functionality migrated from legacy PRs feat(core): Add VCS discovery mechanism #582, feat(templates): Add VCS adaptation templates #583, docs: Add VCS-agnostic documentation and examples #584
• Using hybrid branching: feat/bmvcs-dev for all work
• Target branch for PR: next (not v6-alpha)
• Module is optional - BMM works without BMVCS

📊 Status Update (2025-09-30)

Migration from v4 to v6-alpha architecture complete. All code from legacy PRs #582, #583, #584 successfully consolidated into feat/bmvcs-dev branch.

Current Phase: Pre-Submission Testing ⏳

Following systematic testing approach from NEXT_SESSION.md before creating PR to next branch.

Next action: Execute high-priority testing tasks to validate module functionality.

• 5 workflow templates (GitHub Flow, GitFlow, Trunk-Based, No-VCS, Custom)
• Complete setup workflow
• BMM integration (Architect/PM/Dev agents)
• Comprehensive documentation + examples

📊 Stats

• ~3,500 lines of production code
• 25 files (agent, tasks, templates, workflows, docs, examples)
• Alpha Phase 2 testing complete
• Path fix included (corrected VCS config path in BMM agents)

• Consolidates legacy PRs feat(core): Add VCS discovery mechanism #582, feat(templates): Add VCS adaptation templates #583, docs: Add VCS-agnostic documentation and examples #584 (v4 → v6 migration)
• Complements PR fix: add test and version control requirements to DoD checklist #668 (DoD checklist VCS requirements)

Ready for maintainer review! Thank you for considering this contribution.

I cant imagine the marketshare of many using any version control not using git that are using AI to develop code - has there been a request for other VSC?

[joyshmitz]

Discussing with @thoroc the possibility of automatically determining the git workflow in feat(core): Add VCS discovery mechanism

I made the following suggestion
"Conclusion
Use detection as a HINT, not a DECISION. This aligns with BMAD philosophy:

• Progressive disclosure - Try to detect first
• Respect existing workflows - But confirm with user
• Discovery before assumption - Detection is also discovery.

Think of it like form autocomplete - helpful, but allows correction."

This is where the idea of other possible users in a rarely changing corporate landscape came in.

But if not, then no, you're the boss.
