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
