# KROW Workforce Release Strategy & Tagging Plan

## 📋 Overview

This document establishes a systematic approach to versioning, tagging, and releasing across the KROW Workforce monorepo, which contains 5 distinct products with interdependencies.

**Products:**
1. **Staff Mobile App** - Flutter (iOS/Android)
2. **Client Mobile App** - Flutter (iOS/Android)
3. **Web Dashboard** - React/Vite
4. **Backend Services** - Node.js (Command API, Core API)
5. **Database/DataConnect** - Firebase Data Connect with PostgreSQL

---

## 🔗 Versioning Strategy

### Semantic Versioning (SemVer)

All products follow **Semantic Versioning 2.0.0**:
- **MAJOR.MINOR.PATCH** (e.g., `1.2.3`)
- **MAJOR**: Breaking changes, major features
- **MINOR**: Backward-compatible new features
- **PATCH**: Bug fixes, minor improvements

### Version Independence

Each product maintains its own version:
- Products can release independently
- No requirement for synchronized versions across products
- Allows flexibility in release schedules

### Current Baseline (as of 2026-03-05)

| Product | Current Version | Status |
|---------|-----------------|--------|
| Staff Mobile App | 0.1.0 | Development |
| Client Mobile App | 0.1.0 | Development |
| Web Dashboard | 0.0.0 | Pre-release |
| Backend (Command API) | 0.1.0 | Development |
| Backend (Core API) | 0.1.0 | Development |
| DataConnect | N/A | Schema-driven |

---

## 🏷️ Git Tag Naming Convention

### Format

```
<product>/<environment>-v<version>
```

### Products
- `staff-mobile` - Staff mobile application
- `client-mobile` - Client mobile application
- `web-dashboard` - Web dashboard
- `command-api` - Backend command API
- `core-api` - Backend core API
- `dataconnect` - Database/DataConnect schema

### Environments
- `dev` - Development release (unstable, for testing)
- `staging` - Staging release (pre-production)
- `prod` - Production release (stable, customer-facing)

### Examples
```
staff-mobile/dev-v0.1.0
client-mobile/staging-v0.1.0
web-dashboard/prod-v1.0.0
command-api/dev-v0.2.1
dataconnect/prod-v0.3.0
```

### Release Candidate Suffix (Optional)
For pre-release versions:
```
staff-mobile/staging-v0.1.0-rc.1
web-dashboard/prod-v1.0.0-rc.2
```

---

## 📅 Release Cadence

### Development Releases (`dev`)
- **Frequency**: Weekly or as-needed
- **Trigger**: Completed feature branches, bug fixes
- **Duration**: Not stable, for internal testing
- **Deployment**: Dev environment only

### Staging Releases (`staging`)
- **Frequency**: Bi-weekly
- **Trigger**: Completion of sprint/feature milestone
- **Duration**: Should maintain stability for 1-2 weeks
- **Deployment**: Staging environment for QA

### Production Releases (`prod`)
- **Frequency**: Monthly or sprint-based (typically end of month)
- **Trigger**: Successful staging validation + product sign-off
- **Duration**: Maintain for 2+ months
- **Deployment**: Production environment for customers

---

## 🔄 Release Dependency Order

### Critical Path (Recommended)

**For synchronized releases:**

1. **DataConnect Schema** (if schema changes) - Deploy first
2. **Backend Services** (Command API → Core API)
3. **Web Dashboard**
4. **Mobile Apps** (Staff first, then Client)

**Rationale:**
- DataConnect schema changes must be deployed before APIs consume new fields
- Backend APIs must be stable before frontend depends on new endpoints
- Web can be deployed independently but should test against new backend
- Mobile apps can be released independently but won't have full features until matching backend is live

### Independent Releases

Products can release independently if they don't introduce breaking changes:
- Mobile apps can release without backend changes
- Web dashboard can release bug fixes independently
- Backend can release non-breaking API changes independently

---

## 🔐 Protected Tags

### Rules

- **Production tags (`prod-v*`)**: Require pull request review
- **Staging tags (`staging-v*`)**: Require at least 1 approval
- **Dev tags (`dev-v*`)**: No restrictions

### Implementation in GitHub

1. Go to Repo Settings → Branches → Add rule
2. Apply to tag name pattern: `**/prod-v*`
3. Require pull request reviews before merging
4. Require status checks to pass

## 📝 Version File Locations

### Mobile Apps (Staff & Client)

**File**: `/apps/mobile/apps/staff_app/pubspec.yaml` (and client_app)
```yaml
version: 0.1.0+1

## 🛠️ Git Commands

### Create a Tag

```bash
# Create annotated tag
git tag -a staff-mobile/dev-v0.1.0 -m "Staff mobile v0.1.0 - [feature description]"

# Push tag to remote
git push origin staff-mobile/dev-v0.1.0

# Or push all tags
git push origin --tags
```

### List Tags for a Product

```bash
# Show all staff-mobile tags
git tag -l "staff-mobile/*" --sort=-version:refname

# Show tags in specific environment
git tag -l "*/prod-v*"
```

### Delete a Tag

```bash
# Local deletion
git tag -d staff-mobile/dev-v0.1.0

# Remote deletion
git push origin --delete staff-mobile/dev-v0.1.0
```

## 🔍 Rollback Procedures

### If Critical Issue Found in Prod

1. **Identify**: Determine which product caused the issue
2. **Revert**: 
   ```bash
   git revert <commit-hash> -m 1
   git push origin main
   ```
3. **Tag**: Create hotfix tag
   ```bash
   git tag -a staff-mobile/prod-v0.1.1 -m "Hotfix: [issue description]"
   git push origin staff-mobile/prod-v0.1.1
   ```
4. **Deploy**: Follow deployment checklist
5. **Communication**: Notify users and stakeholders

### If Staging Issue Found

Similar to rollback but to staging environment. No customer impact.
