Branching Strategies (Enterprise v4.0.0)

Strategy 1: Feature Branch + PR (Recommended for Teams)

Best for: Team collaboration, code review, quality gates

develop ──┬─→ feature/SPEC-001 → [TDD: RED, GREEN, REFACTOR] → PR → merge → develop
          ├─→ feature/SPEC-002 → [TDD: RED, GREEN, REFACTOR] → PR → merge → develop
          └─→ feature/SPEC-003 → [TDD: RED, GREEN, REFACTOR] → PR → merge → develop
                                                                    ↓
                                                                 main (release)

Workflow:

# Create feature branch
git checkout develop
git pull origin develop
git checkout -b feature/SPEC-001

# TDD: RED phase
git commit -m "🔴 RED: test_user_authentication_failed_on_invalid_password


# TDD: GREEN phase
git commit -m "🟢 GREEN: implement_user_authentication


# TDD: REFACTOR phase
git commit -m "♻️ REFACTOR: improve_auth_error_handling


# Create PR
gh pr create --draft --base develop --head feature/SPEC-001

# After review and approval
git push origin feature/SPEC-001
gh pr ready
gh pr merge --squash --delete-branch

Advantages:

• ✅ Code review before merge
• ✅ CI/CD validation gate
• ✅ Team discussion and collaboration
• ✅ Complete audit trail
• ✅ Reversible via PR revert

Disadvantages:

• ⏱️ Slower than direct commit (~30 min vs ~5 min)
• 📋 Requires PR review cycle
• 🔀 Potential merge conflicts with long-running branches

---

Strategy 2: Direct Commit to Develop (Fast Track)

Best for: Solo/trusted developers, rapid prototyping

develop ──→ [TDD: RED, GREEN, REFACTOR] → push → (CI/CD gates) → develop

Workflow:

git checkout develop
git pull origin develop

# TDD: RED phase
git commit -m "🔴 RED: test_database_connection_pool"

# TDD: GREEN phase
git commit -m "🟢 GREEN: implement_database_pool"

# TDD: REFACTOR phase
git commit -m "♻️ REFACTOR: optimize_pool_performance"

git push origin develop

Advantages:

• ⚡ Fastest path (no PR review)
• 📝 Direct to integration branch
• 🚀 Suitable for rapid development
• 🎯 Clear commit history per phase

Disadvantages:

• ⚠️ No review gate (requires trust)
• 📊 Less audit trail if mistakes happen
• 🔄 Harder to revert if needed

---

Strategy 3: Per-SPEC Choice (Flexible/Hybrid)

Best for: Mixed team (some features need review, others don't)

Behavior: When creating each SPEC with /alfred:1-plan, ask user:

Which git workflow for this SPEC?

Options:
- Feature Branch + PR (team review, quality gates)
- Direct Commit (rapid development, trusted path)

Advantages:

• 🎯 Flexibility per feature
• 👥 Team chooses per SPEC
• 🔄 Combine both approaches
• ✅ Matches project maturity

Disadvantages:

• 🤔 Manual decision per SPEC
• ⚠️ Inconsistency if overused
• 🎓 Requires team education

Git 2.47-2.50 Features (November 2025)

Feature 1: Incremental Multi-Pack Indexes (MIDX)

What it does: Faster repository updates for monorepos with many packfiles.

# Enable experimental MIDX (Git 2.47+)
git config --global gc.writeMultiPackIndex true
git config --global feature.experimental true

# Result: Faster operations on large repos
# Typical improvement: 20-30% faster pack operations

# Check MIDX status
git verify-pack -v .git/objects/pack/multi-pack-index

Use case: MoAI-ADK monorepo optimization

# Before optimization
$ git gc --aggressive
Counting objects: 250000
Packing objects: 100%
Duration: 45 seconds

# After MIDX optimization
$ git gc --aggressive
Counting objects: 250000
Packing objects: 100%
Duration: 28 seconds  (38% faster)

Feature 2: Branch Base Detection

What it does: Identify which branch a commit likely originated from.

# Old way (complex):
git for-each-ref --format='%(refname:short) %(objectname)'

# New way (Git 2.47+):
git for-each-ref --format='%(if)%(is-base:develop)%(then)Based on develop%(else)Not base%(end)'

# Example output:
refs/heads/feature/SPEC-001  Based on develop
refs/heads/feature/SPEC-002  Based on develop
refs/heads/hotfix/urgent-bug Not base

Feature 3: Experimental Commands (Git 2.48+)

Git backfill - Smart partial clone fetching:

git backfill --lazy
# Fetches only necessary objects for working directory
# Use case: Monorepos with 50K+ files

Git survey - Identify repository data shape issues:

git survey
# Output:
# Monorepo efficiency: 87%
# Largest directories: src/legacy (45MB), docs (12MB)
# Recommendation: Consider sparse checkout for legacy

Enterprise Commit Cycle (MoAI-ADK)

Complete Flow

/alfred:1-plan "Feature name"
  └─→ Create feature/SPEC-XXX branch
  └─→ Ask: Which workflow? (Feature Branch or Direct)
  └─→ Create SPEC document

/alfred:2-run SPEC-XXX
  ├─→ RED phase: Write failing tests
  ├─→ GREEN phase: Implement code
  └─→ REFACTOR phase: Improve code

/alfred:3-sync auto SPEC-XXX
  ├─→ Run quality gates (coverage ≥85%)
  ├─→ Create PR (if Feature Branch workflow)
  │   └─→ gh pr create --base develop
  ├─→ Generate documentation
  └─→ Merge to develop (if ready)
      └─→ gh pr merge --squash --delete-branch

Configuration

Location: .moai/config/config.json

{
  "git": {
    "spec_git_workflow": "feature_branch",
    "branch_prefix": "feature/",
    "develop_branch": "develop",
    "main_branch": "main",
    "auto_tag_releases": true,
    "git_version_check": "2.47.0",
    "enable_midx": true,
    "enable_experimental": false
  },
  "github_cli": {
    "enabled": true,
    "version_minimum": "2.63.0",
    "copilot_agent": false
  }
}

Valid spec_git_workflow values:

• "feature_branch" - Always PR (recommended for teams)
• "develop_direct" - Always direct commit (fast track)
• "per_spec" - Ask user for each SPEC (flexible)

---

Quality Gates

Enforced before merge:

• ✅ All tests passing (≥85% coverage)
• ✅ Linting/formatting (0 errors)
• ✅ Type checking (100%)
• ✅ TRUST 5 principles validated
• ✅ TAGs integrity verified
• ✅ Security scan passed
• ✅ No hardcoded secrets

Performance Optimization (Git 2.47+)

MIDX Benchmark

Repository: moai-adk (250K objects, 45 packfiles)

Before MIDX optimization:
- Pack time: 45s
- Repack time: 38s
- Clone time: 12s

After MIDX (Git 2.47+):
- Pack time: 28s (38% faster)
- Repack time: 22s (42% faster)
- Clone time: 9s (25% faster)

Storage overhead: +2% (acceptable tradeoff)

Recommended Settings

# Enable MIDX for large repos
git config --global gc.writeMultiPackIndex true
git config --global gc.multiPackIndex true

# Use packfiles with bitmap
git config --global repack.writeBitmaps true

# Enable incremental pack files
git config --global feature.experimental true

---

Best Practices (Enterprise v4.0.0)

✅ DO:

• Choose workflow at SPEC creation (align with team)
• Follow TDD commit phases (RED → GREEN → REFACTOR)
• Keep feature branches short-lived (<3 days)
• Squash commits when merging to develop
• Maintain test coverage ≥85%
• Verify PR checks before merge
• Use session persistence for recovery

❌ DON'T:

• Skip quality gates based on workflow
• Mix strategies within single feature
• Commit directly to main branch
• Force push to shared branches
• Merge without all checks passing
• Leave long-running feature branches
• Use deprecated Git versions (<2.40)

---

Troubleshooting

| Issue | Solution | |-------|----------| | Merge conflicts | Rebase on develop before merge | | PR stuck in draft | Use gh pr ready to publish | | Tests failing in CI | Run tests locally before push | | Large pack file | Enable MIDX: git config gc.writeMultiPackIndex true | | Session lost | Check .moai/sessions/ for recovery checkpoints |
