+## Git Workflow for Contributors
+
+### One-Time Setup
+
+After forking and cloning the repository, set up your development environment:
+
+```bash
+# 1. Add the upstream remote (main repository)
+git remote add upstream git@github.com:bmad-code-org/BMAD-METHOD.git
+
+# 2. Enable git hooks (enforces workflow automatically)
+git config core.hooksPath .githooks
+```
+
+### Single-Commit Workflow
+
+**This repository uses a single-commit-per-branch workflow** to keep PR history clean.
+
+#### Initial Development
+
+```bash
+# Create feature branch
+git checkout -b feat/your-feature
+
+# Make your changes
+# ... edit files ...
+
+# Commit once
+git commit -m "feat: add your feature description"
+
+# Push to your fork
+git push -u origin feat/your-feature
+```
+
+#### Making Additional Changes
+
+**Use amend instead of creating new commits:**
+
+```bash
+# Make more changes
+# ... edit files ...
+
+# Stage changes
+git add .
+
+# Amend the existing commit
+git commit --amend --no-edit
+
+# Force push (safely)
+git push --force-with-lease
+```
+
+#### Addressing PR Feedback
+
+```bash
+# Make requested changes
+# ... edit files ...
+
+# Amend (don't create new commits)
+git commit --amend --no-edit
+
+# Force push
+git push --force-with-lease
+```
+
+### Keeping Your Branch Updated
+
+```bash
+# Sync your local main with upstream
+git checkout main
+git pull upstream main
+
+# Rebase your feature branch
+git checkout feat/your-feature
+git rebase main
+
+# Force push (safely)
+git push --force-with-lease
+```
+
+### What the Git Hooks Do
+
+The hooks in `.githooks/` automate workflow enforcement:
+
+| Hook | Purpose |
+|------|---------|
+| `pre-push` | Ensures upstream sync, blocks direct push to main, enforces single-commit |
+| `pre-commit` | Blocks commits to main, reminds about amend workflow |
+| `post-checkout` | Provides sync reminders when switching branches |
+
+**The hooks will automatically:**
+- Block commits directly to main branch
+- Prevent pushing more than 1 commit per branch
+- Warn if your local main is behind upstream
+- Remind you to rebase before pushing
+
+### Troubleshooting
+
+#### "Too many commits" error
+
+If you have multiple commits, squash them:
+
+```bash
+# Reset to main (keeps your changes)
+git reset --soft main
+
+# Create single commit
+git commit -m "feat: your feature description"
+
+# Force push
+git push --force-with-lease
+```
+
+#### Local main diverged from upstream
+
+```bash
+# Reset your main to match upstream
+git checkout main
+git reset --hard upstream/main
+git push --force-with-lease origin main
+```
+
+#### Branch not rebased on main
+
+```bash
+# Update main first
+git checkout main
+git pull upstream main
+
+# Rebase your branch
+git checkout feat/your-feature
+git rebase main
+
+# Force push
+git push --force-with-lease
+```

+## Multi-Scope Parallel Development
+
+BMad supports running multiple workflows in parallel across different terminal sessions with isolated artifacts. Perfect for:
+
+- **Multi-team projects** — Each team works in their own scope
+- **Parallel feature development** — Develop auth, payments, and catalog simultaneously
+- **Microservices** — One scope per service with shared contracts
+- **Experimentation** — Create isolated scopes for spikes and prototypes
+
+### Quick Start
+
+```bash
+# Initialize scope system
+npx bmad-fh scope init
+
+# Create a scope (you'll be prompted to activate it)
+npx bmad-fh scope create auth --name "Authentication Service"
+# ✓ Scope 'auth' created successfully!
+# ? Set 'auth' as your active scope for this session? (Y/n)
+
+# Run workflows - artifacts now go to _bmad-output/auth/
+# The active scope is stored in .bmad-scope file
+
+# For parallel development in different terminals:
+# Terminal 1:
+npx bmad-fh scope set auth     # Activate auth scope
+# Terminal 2:
+npx bmad-fh scope set payments # Activate payments scope
+
+# Share artifacts between scopes
+npx bmad-fh scope sync-up auth       # Promote to shared layer
+npx bmad-fh scope sync-down payments # Pull shared updates
+```
+
+> **Important:** Workflows only use scoped directories when a scope is active.
+> After creating a scope, accept the prompt to activate it, or run `scope set <id>` manually.

+
+### Create Options
+
+```bash
+npx bmad-fh scope create auth \
+  --name "Authentication Service" \
+  --description "User auth, SSO, and session management" \
+  --deps users,notifications \
+  --context  # Create scope-specific project-context.md
+```
+
+### Directory Structure
+
+After initialization and scope creation:
+
+```

+
+### Access Model
+
+Scopes follow a "read-any, write-own" isolation model:
+
+| Operation | Own Scope | Other Scopes | \_shared/   |
+| --------- | --------- | ------------ | ----------- |
+| **Read**  | Allowed   | Allowed      | Allowed     |
+| **Write** | Allowed   | Blocked      | via sync-up |
+
+### Workflow Integration
+
+Workflows (run via agent menus like `CP` for Create PRD, `DS` for Dev Story) automatically detect and use scope context. Resolution order:
+
+1. Session context from `.bmad-scope` file (set via `scope set`)
+2. `BMAD_SCOPE` environment variable
+3. Prompt user to select or create scope
+
+**Setting your active scope:**
+
+```bash
+# Set scope for your terminal session
+npx bmad-fh scope set auth
+
+# Or use environment variable (useful for CI/CD)
+export BMAD_SCOPE=auth
+```
+
+**Scope-aware path variables in workflows:**
+
+- `{scope}` → Scope ID (e.g., "auth")
+- `{scope_path}` → `_bmad-output/auth`
+- `{scope_planning}` → `_bmad-output/auth/planning-artifacts`
+- `{scope_implementation}` → `_bmad-output/auth/implementation-artifacts`
+- `{scope_tests}` → `_bmad-output/auth/tests`
+
+### Getting Help
+
+```bash
+# Show comprehensive help for all scope commands
+npx bmad-fh scope help
+
+# Get detailed help for a specific command
+npx bmad-fh scope help create
+npx bmad-fh scope help sync-up
+```

+
+# Migration Guide: Multi-Scope Parallel Artifacts
+
+> Guide for migrating existing BMAD installations to the multi-scope system.
+
+## Overview
+
+The multi-scope system introduces isolated artifact workspaces while maintaining full backward compatibility. Existing installations can:
+
+1. Continue working without any changes (legacy mode)
+2. Migrate existing artifacts to a `default` scope
+3. Create new scopes for parallel development
+
+## Prerequisites
+
+- BMAD v6+ installed
+- Node.js 20+
+- Backup of your `_bmad-output/` directory (recommended)
+
+## Migration Paths
+
+### Path 1: Continue Without Migration (Recommended for Simple Projects)
+
+If you have a single-team, single-product workflow, you can continue using BMAD without migration. The scope system is entirely opt-in.
+
+**When to choose this path:**
+
+- Small to medium projects
+- Single developer or tightly coordinated team
+- No need for parallel feature development
+
+**What happens:**
+
+- Workflows continue to use `_bmad-output/` directly
+- No scope variable in paths
+- All existing commands work unchanged
+
+### Path 2: Migrate to Default Scope (Recommended for Growing Projects)
+
+Migrate existing artifacts to a `default` scope, enabling future parallel development.
+
+```bash
+# 1. Analyze current state
+bmad scope migrate --analyze
+
+# 2. Run migration (creates backup automatically)
+bmad scope migrate
+
+# 3. Verify migration
+bmad scope list
+bmad scope info default
+```
+
+**What happens:**
+
+- Creates backup at `_bmad-output/_backup_migration_<timestamp>/`
+- Initializes scope system
+- Creates `default` scope
+- Moves artifacts from `_bmad-output/` to `_bmad-output/default/`
+- Updates references in state files
+- Creates shared layer at `_bmad-output/_shared/`
+
+### Path 3: Fresh Start with Scopes
+
+For new projects or major rewrites, start fresh with the scope system.
+
+```bash
+# Initialize scope system
+bmad scope init
+
+# Create your first scope
+bmad scope create main --name "Main Product"
+
+# Run workflows with scope
+bmad workflow create-prd --scope main
+```
+
+## Step-by-Step Migration
+
+### Step 1: Backup (Automatic but Verify)
+
+The migration creates an automatic backup, but we recommend creating your own:
+
+```bash
+# Manual backup
+cp -r _bmad-output/ _bmad-output-backup-$(date +%Y%m%d)/
+```
+
+### Step 2: Analyze Current State
+
+```bash
+bmad scope migrate --analyze
+```
+
+**Example output:**
+
+```
+Migration Analysis
+==================
+
+Current Structure:
+  _bmad-output/
+  ├── planning-artifacts/
+  │   ├── prd.md
+  │   ├── architecture.md
+  │   └── epics-stories.md
+  ├── implementation-artifacts/
+  │   ├── sprint-status.yaml
+  │   └── stories/
+  └── tests/
+      └── ...
+
+Detected Artifacts:
+  Planning: 3 files
+  Implementation: 15 files
+  Tests: 8 files
+
+Migration Plan:
+  1. Create backup
+  2. Initialize scope system
+  3. Create 'default' scope
+  4. Move all artifacts to default/
+  5. Create shared layer
+  6. Update state references
+
+Estimated time: < 30 seconds
+```
+
+### Step 3: Run Migration
+
+```bash
+bmad scope migrate
+```
+
+**Interactive prompts:**
+
+```
+? Ready to migrate existing artifacts to 'default' scope? (Y/n)
+? Create scope-specific project-context.md? (y/N)
+```
+
+### Step 4: Verify Migration
+
+```bash
+# Check scope list
+bmad scope list
+
+# Verify directory structure
+ls -la _bmad-output/
+
+# Check default scope
+bmad scope info default
+```
+
+**Expected structure after migration:**
+
+```
+_bmad-output/
+├── _shared/
+│   ├── project-context.md
+│   ├── contracts/
+│   └── principles/
+├── default/
+│   ├── planning-artifacts/
+│   │   ├── prd.md
+│   │   ├── architecture.md
+│   │   └── epics-stories.md
+│   ├── implementation-artifacts/
+│   │   ├── sprint-status.yaml
+│   │   └── stories/
+│   ├── tests/
+│   └── .scope-meta.yaml
+└── _backup_migration_<timestamp>/
+    └── (original files)
+```
+
+### Step 5: Update Workflows (Optional)
+
+If you have custom workflow configurations, update paths:
+
+**Before:**
+
+```yaml
+output_dir: '{output_folder}/planning-artifacts'
+```
+
+**After:**
+
+```yaml
+output_dir: '{scope_planning}'
+# Or: "{output_folder}/{scope}/planning-artifacts"
+```
+
+The migration script can update workflows automatically:
+
+```bash
+node tools/cli/scripts/migrate-workflows.js --dry-run --verbose
+node tools/cli/scripts/migrate-workflows.js
+```
+
+## Rollback Procedure
+
+If migration fails or you need to revert:
+
+### Automatic Rollback
+
+```bash
+bmad scope migrate --rollback
+```
+
+### Manual Rollback
+
+```bash
+# Remove migrated structure
+rm -rf _bmad-output/default/
+rm -rf _bmad-output/_shared/
+rm -rf _bmad/_config/scopes.yaml
+rm -rf _bmad/_events/
+
+# Restore from backup
+cp -r _bmad-output/_backup_migration_<timestamp>/* _bmad-output/
+rm -rf _bmad-output/_backup_migration_<timestamp>/
+```
+
+## Post-Migration Steps
+
+### 1. Update .gitignore
+
+Add scope-related files to ignore:
+
+```gitignore
+# Scope session file (user-specific)
+.bmad-scope
+
+# Lock files
+*.lock
+
+# Backup directories (optional)
+_bmad-output/_backup_*/
+```
+
+### 2. Update Team Documentation
+
+Inform your team about the new scope system:
+
+- How to create scopes
+- How to run workflows with scopes
+- How to use sync-up/sync-down
+
+### 3. Configure Scope Dependencies (Optional)
+
+If your scopes have dependencies:
+
+```bash
+# Update scope with dependencies
+bmad scope update default --deps shared-lib,core-api
+```
+
+### 4. Set Up Event Subscriptions (Optional)
+
+For multi-scope projects:
+
+```bash
+# Edit subscriptions manually
+# _bmad/_events/subscriptions.yaml
+```
+
+```yaml
+subscriptions:
+  frontend:
+    watch:
+      - scope: api
+        patterns: ['contracts/*']
+    notify: true
+```
+
+## Troubleshooting
+
+### Error: "Artifacts not found after migration"
+
+**Cause:** Migration path resolution issue.
+
+**Solution:**
+
+```bash
+# Check backup location
+ls _bmad-output/_backup_migration_*/
+
+# Manually move if needed
+mv _bmad-output/_backup_migration_*/planning-artifacts/* _bmad-output/default/planning-artifacts/
+```
+
+### Error: "Scope not found"
+
+**Cause:** Scope system not initialized.
+
+**Solution:**
+
+```bash
+bmad scope init
+```
+
+### Error: "Cannot write to scope 'default' while in scope 'other'"
+
+**Cause:** Cross-scope write protection.
+
+**Solution:**
+
+```bash
+# Either switch scope
+bmad workflow --scope default
+
+# Or use sync to share
+bmad scope sync-up other
+bmad scope sync-down default
+```
+
+### State Files Show Old Paths
+
+**Cause:** References not updated during migration.
+
+**Solution:**
+
+```bash
+# Re-run migration with force update
+bmad scope migrate --force --update-refs
+```
+
+## FAQ
+
+### Q: Will my existing workflows break?
+
+**A:** No. The scope system is backward compatible. Workflows without `{scope}` variables continue to work. Only workflows with scope variables require an active scope.
+
+### Q: Can I have both scoped and non-scoped artifacts?
+
+**A:** Yes, but not recommended. The `_shared/` layer is for cross-scope artifacts. Keep everything in scopes for consistency.
+
+### Q: How do I share artifacts between team members?
+
+**A:** Use git as usual. The `_bmad-output/` directory structure (including scopes) can be committed. Add `.bmad-scope` to `.gitignore` (session-specific).
+
+### Q: Can I rename scopes?
+
+**A:** Not directly. Create new scope, copy artifacts, remove old scope:
+
+```bash
+bmad scope create new-name --name "New Name"
+cp -r _bmad-output/old-name/* _bmad-output/new-name/
+bmad scope remove old-name --force
+```
+
+### Q: What happens to sprint-status.yaml?
+
+**A:** Each scope gets its own `sprint-status.yaml` at `_bmad-output/{scope}/implementation-artifacts/sprint-status.yaml`. This enables parallel sprint planning.
+
+### Q: Do I need to update my CI/CD?
+
+**A:** Only if your CI/CD references specific artifact paths. Update paths to include scope:
+
+```bash
+# Before
+cat _bmad-output/planning-artifacts/prd.md
+
+# After
+cat _bmad-output/default/planning-artifacts/prd.md
+```

+
+# Multi-Scope Parallel Artifacts Guide
+
+> Run multiple workflows in parallel across different terminal sessions with isolated artifacts.
+
+## Overview
+
+The multi-scope system enables parallel development by isolating artifacts into separate "scopes". Each scope is an independent workspace with its own:
+
+- Planning artifacts (PRDs, architecture, epics)
+- Implementation artifacts (sprint status, stories)
+- Test directories
+- Optional scope-specific project context
+
+## Quick Start
+
+### Initialize Scope System
+
+```bash
+npx bmad-fh scope init
+```
+
+This creates:
+
+- `_bmad/_config/scopes.yaml` - Scope registry
+- `_bmad-output/_shared/` - Shared knowledge layer
+- `_bmad/_events/` - Event system
+
+### Create Your First Scope
+
+```bash
+npx bmad-fh scope create auth --name "Authentication Service"
+```
+
+**Important:** After creation, you'll be prompted to activate the scope:
+
+```
+✓ Scope 'auth' created successfully!
+? Set 'auth' as your active scope for this session? (Y/n)
+```
+
+Accept this prompt (or run `npx bmad-fh scope set auth` later) to ensure workflows use the scoped directories.
+
+### List Scopes
+
+```bash
+npx bmad-fh scope list
+```
+
+### Activate a Scope
+
+```bash
+# Set the active scope for your terminal session
+npx bmad-fh scope set auth
+
+# Or use environment variable (useful for CI/CD)
+export BMAD_SCOPE=auth
+```
+
+Workflows automatically detect the active scope from:
+
+1. `.bmad-scope` file (set by `scope set` command)
+2. `BMAD_SCOPE` environment variable
+
+> **Warning:** If no scope is active, artifacts go to root `_bmad-output/` directory (legacy mode).
+

+```
+
+> **Note:** After creation, you'll be prompted to set this as your active scope.
+> Accept the prompt to ensure workflows use the scoped directories.
+
+### Remove with Backup
+
+```bash
+# Creates backup in _bmad-output/_backup_auth_<timestamp>

+```
+
+## Syncing Between Scopes
+
+### Promote to Shared Layer
+
+```bash
+# Promote artifacts to shared
+bmad scope sync-up auth
+```
+
+Promotes:
+
+- `architecture/*.md`
+- `contracts/*.md`
+- `principles/*.md`
+- `project-context.md`
+
+### Pull from Shared Layer
+
+```bash
+# Pull shared updates to scope
+bmad scope sync-down payments
+```
+
+## Access Model
+
+| Operation | Scope: auth | Scope: payments | \_shared    |
+| --------- | ----------- | --------------- | ----------- |
+| **Read**  | Any scope   | Any scope       | Yes         |
+| **Write** | auth only   | payments only   | Use sync-up |
+
+### Isolation Modes
+
+Configure in `_bmad/_config/scopes.yaml`:
+
+```yaml
+settings:
+  isolation_mode: strict # strict | warn | permissive
+```
+
+- **strict**: Block cross-scope writes (default)
+- **warn**: Allow with warnings
+- **permissive**: Allow all (not recommended)
+
+## Workflow Integration
+
+### Scope Variable
+
+Workflows use `{scope}` variable:
+
+```yaml
+# workflow.yaml
+variables:
+  test_dir: '{scope_tests}' # Resolves to _bmad-output/auth/tests
+```
+
+### Scope-Aware Paths
+
+| Variable                 | Non-scoped                             | Scoped (auth)                               |
+| ------------------------ | -------------------------------------- | ------------------------------------------- |
+| `{scope}`                | (empty)                                | auth                                        |
+| `{scope_path}`           | \_bmad-output                          | \_bmad-output/auth                          |
+| `{scope_planning}`       | \_bmad-output/planning-artifacts       | \_bmad-output/auth/planning-artifacts       |
+| `{scope_implementation}` | \_bmad-output/implementation-artifacts | \_bmad-output/auth/implementation-artifacts |
+| `{scope_tests}`          | \_bmad-output/tests                    | \_bmad-output/auth/tests                    |
+
+## Session-Sticky Scope
+
+The `.bmad-scope` file in project root stores active scope:
+
+```yaml
+# .bmad-scope (gitignored)
+active_scope: auth
+set_at: '2026-01-21T10:00:00Z'
+```
+
+Workflows automatically use this scope when no `--scope` flag provided.
+
+## Event System
+
+### Subscribing to Updates
+
+Scopes can subscribe to events from other scopes:
+
+```yaml
+# _bmad/_events/subscriptions.yaml
+subscriptions:
+  payments:
+    watch:
+      - scope: auth
+        patterns: ['contracts/*', 'architecture.md']
+    notify: true
+```
+
+### Event Types
+
+- `artifact_created` - New artifact created
+- `artifact_updated` - Artifact modified
+- `artifact_promoted` - Promoted to shared
+- `sync_up` / `sync_down` - Sync operations
+- `scope_created` / `scope_archived` - Scope lifecycle
+
+## Parallel Development Example
+
+### Terminal 1: Auth Scope
+
+```bash
+# Set scope for session
+bmad scope create auth --name "Authentication"
+
+# Run workflows - all output goes to auth scope
+bmad workflow create-prd --scope auth
+bmad workflow create-epic --scope auth
+```
+
+### Terminal 2: Payments Scope
+
+```bash
+# Different scope, isolated artifacts
+bmad scope create payments --name "Payment Processing"
+
+bmad workflow create-prd --scope payments
+bmad workflow create-epic --scope payments
+```
+
+### Sharing Work
+
+```bash
+# Terminal 1: Promote auth architecture to shared
+bmad scope sync-up auth
+
+# Terminal 2: Pull shared updates to payments
+bmad scope sync-down payments
+```
+
+## Migration from Non-Scoped
+
+Existing projects can migrate:
+
+```bash
+# Analyze existing artifacts
+bmad scope migrate --analyze
+
+# Migrate to 'default' scope
+bmad scope migrate
+```
+
+This:
+
+1. Creates backup
+2. Creates `default` scope
+3. Moves artifacts to `_bmad-output/default/`
+4. Updates references
+
+## Best Practices
+
+### Naming Scopes
+
+Use clear, descriptive IDs:
+
+- `auth` - Authentication service
+- `payments` - Payment processing
+- `user-service` - User management
+- `api-gateway` - API gateway
+
+### Scope Granularity
+
+Choose based on:
+
+- **Team boundaries** - One scope per team
+- **Deployment units** - One scope per service
+- **Feature sets** - One scope per major feature
+
+### Shared Layer Usage
+
+- Keep `project-context.md` as the global "bible"
+- Put integration contracts in `_shared/contracts/`
+- Document architecture principles in `_shared/principles/`
+- Promote mature, stable artifacts only
+
+### Dependencies
+
+Declare dependencies explicitly:
+
+```bash
+bmad scope create payments --deps auth,users
+```
+
+This helps:
+
+- Track relationships
+- Get notifications on dependency changes
+- Plan integration work
+
+## Troubleshooting
+
+### "No scope set" Error
+
+```bash
+# Option 1: Specify scope explicitly
+bmad workflow --scope auth
+
+# Option 2: Set session scope
+bmad scope create auth
+```
+
+### Cross-Scope Write Blocked
+
+```
+Error: Cannot write to scope 'payments' while in scope 'auth'
+```
+
+Solutions:
+
+1. Switch to correct scope
+2. Use sync-up to promote to shared
+3. Change isolation mode (not recommended)
+
+### Conflict During Sync
+
+```bash
+# Keep local version
+bmad scope sync-down payments --resolution keep-local
+
+# Keep shared version
+bmad scope sync-down payments --resolution keep-shared
+
+# Backup and update
+bmad scope sync-down payments --resolution backup-and-update
+```
+
+## API Reference
+
+### ScopeManager
+
+```javascript
+const { ScopeManager } = require('./src/core/lib/scope');
+
+const manager = new ScopeManager({ projectRoot: '/path/to/project' });
+await manager.initialize();
+
+// CRUD operations
+const scope = await manager.createScope('auth', { name: 'Auth' });
+const scopes = await manager.listScopes();
+await manager.archiveScope('auth');
+await manager.removeScope('auth', { force: true });
+```
+
+### ScopeContext
+
+```javascript
+const { ScopeContext } = require('./src/core/lib/scope');
+
+const context = new ScopeContext({ projectRoot: '/path/to/project' });
+
+// Session management
+await context.setScope('auth');
+const current = await context.getCurrentScope();
+
+// Load merged context
+const projectContext = await context.loadProjectContext('auth');
+```
+
+### ArtifactResolver
+
+```javascript
+const { ArtifactResolver } = require('./src/core/lib/scope');
+
+const resolver = new ArtifactResolver({
+  currentScope: 'auth',
+  basePath: '_bmad-output',
+});
+
+// Check access
+const canWrite = resolver.canWrite('/path/to/file.md');
+resolver.validateWrite('/path/to/file.md'); // Throws if not allowed
+```

+# Multi-Scope Parallel Artifacts System - Implementation Plan
+
+> **Status:** Planning Complete  
+> **Created:** 2026-01-21  
+> **Last Updated:** 2026-01-21  
+> **Estimated Effort:** 17-22 days
+
+## Executive Summary
+
+This plan outlines the implementation of a **multi-scope parallel artifact system** for BMAD that enables:
+
+- Running multiple workflows in parallel across different terminal sessions
+- Each session works on a different sub-product (scope) with isolated artifacts
+- Shared knowledge layer with bidirectional synchronization
+- Event-based updates when dependencies change
+- Strict write isolation with liberal read access

+## Key Design Decisions
+
+| Decision                     | Choice                    | Rationale                                                                         |
+| ---------------------------- | ------------------------- | --------------------------------------------------------------------------------- |
+| **Sprint-status handling**   | Per-scope                 | Each scope has independent sprint planning, no parallel conflicts                 |
+| **Project-context location** | Both (global + per-scope) | Global "bible" in `_shared/`, optional scope-specific that extends                |
+| **Scope vs Module**          | Different concepts        | Module = code organization (bmm/core), Scope = artifact isolation (auth/payments) |
+| **Cross-scope access**       | Read any, write own       | Liberal reads for dependency awareness, strict writes for isolation               |
+| **Test directories**         | Scoped                    | `{output_folder}/{scope}/tests` for full isolation                                |
+| **Workflow updates**         | Automated script          | Handle 22+ workflow.yaml files programmatically                                   |
+| **File locking**             | proper-lockfile npm       | Battle-tested, cross-platform locking                                             |
+| **Git hooks**                | This repo only            | For contributor workflow, NOT installed with bmad                                 |
+| **Migration strategy**       | Auto-migrate to 'default' | Existing artifacts move to default scope automatically                            |
+| **Scope ID format**          | Strict                    | Lowercase alphanumeric + hyphens only                                             |

+## Phase 0: Git Hooks (This Repo)
+
+> **Estimate:** 0.5 day  
+> **Purpose:** Contributor workflow for BMAD-METHOD repository only
+
+### Objectives
+
+- Ensure main branch always synced with upstream (bmad-code-org)
+- Enforce single-commit-per-branch workflow
+- Require rebase on main before push
+- Use amend + force-with-lease pattern
+
+### Files to Create
+
+```
+BMAD-METHOD/
+├── .githooks/
+│   ├── pre-push           # Main enforcement hook
+│   ├── pre-commit         # Block main commits, amend warnings
+│   └── post-checkout      # Sync reminders
+└── docs/
+    └── CONTRIBUTING.md    # Git workflow documentation
+```
+
+### Pre-Push Hook Logic
+
+```bash
+#!/bin/bash
+# .githooks/pre-push
+
+1. Ensure upstream remote exists (git@github.com:bmad-code-org/BMAD-METHOD.git)
+2. Fetch upstream
+3. Block direct push to main
+4. Sync local main with upstream (if needed)
+5. Check branch is rebased on main
+6. Enforce single commit rule (max 1 commit ahead of main)
+```
+
+### Setup Instructions
+
+```bash
+# One-time setup for contributors
+git config core.hooksPath .githooks
+git remote add upstream git@github.com:bmad-code-org/BMAD-METHOD.git
+```
+
+---
+
+## Phase 1: Scope Foundation
+
+> **Estimate:** 3-4 days
+
+### 1.1 Scopes.yaml Schema
+
+**File:** `_bmad/_config/scopes.yaml`
+
+```yaml
+version: 1
+
+settings:
+  allow_adhoc_scopes: true # Allow on-demand scope creation
+  isolation_mode: strict # strict | warn | permissive
+  default_output_base: '_bmad-output'
+  default_shared_path: '_bmad-output/_shared'
+
+scopes:
+  auth:
+    id: 'auth'
+    name: 'Authentication Service'
+    description: 'User authentication, SSO, authorization'
+    status: active # active | archived
+    dependencies: [] # Scopes this depends on
+    created: '2026-01-21T10:00:00Z'
+    _meta:
+      last_activity: '2026-01-21T15:30:00Z'
+      artifact_count: 12
+```
+
+**Validation Rules:**
+
+- Scope ID: `^[a-z][a-z0-9-]*[a-z0-9]$` (2-50 chars)
+- Reserved IDs: `_shared`, `_events`, `_config`, `global`
+- Circular dependency detection required
+
+### 1.2 ScopeManager Class
+
+**File:** `src/core/scope/scope-manager.js`
+
+```javascript
+class ScopeManager {
+  // CRUD Operations
+  async listScopes(filters)
+  async getScope(scopeId)
+  async createScope(scopeId, options)
+  async updateScope(scopeId, updates)
+  async removeScope(scopeId, options)
+
+  // Path Resolution
+  async getScopePaths(scopeId)
+  resolvePath(template, scopeId)
+
+  // Validation
+  validateScopeId(scopeId)
+  validateDependencies(scopeId, dependencies, allScopes)
+
+  // Dependencies
+  async getDependencyTree(scopeId)
+  findDependentScopes(scopeId, allScopes)
+}
+```
+
+### 1.3 CLI Commands
+
+**File:** `tools/cli/commands/scope.js`
+
+| Command                  | Description                          |
+| ------------------------ | ------------------------------------ |
+| `bmad scope list`        | List all scopes                      |
+| `bmad scope create <id>` | Create new scope interactively       |
+| `bmad scope info <id>`   | Show scope details                   |
+| `bmad scope remove <id>` | Remove scope                         |
+| `bmad scope migrate`     | Migrate existing to scoped structure |
+
+### 1.4 Directory Structure Generator
+
+**File:** `src/core/scope/scope-initializer.js`
+
+Creates on scope creation:
+
+```
+_bmad-output/{scope}/
+├── planning-artifacts/
+├── implementation-artifacts/
+├── tests/
+└── .scope-meta.yaml
+```
+
+Creates on first scope (one-time):
+
+```
+_bmad-output/_shared/
+├── project-context.md      # Global project context template
+├── contracts/
+└── principles/
+
+_bmad/_events/
+├── event-log.yaml
+└── subscriptions.yaml
+```
+
+### 1.5 Migration Logic
+
+**File:** `src/core/scope/scope-migrator.js`
+
+Steps:
+
+1. Create backup of `_bmad-output/`
+2. Initialize scope system
+3. Create `default` scope
+4. Move existing artifacts to `_bmad-output/default/`
+5. Update references in state files
+6. Mark migration complete
+
+---
+
+## Phase 2: Variable Resolution
+
+> **Estimate:** 4-5 days
+
+### 2.1 workflow.xml Scope Initialization
+
+**File:** `src/core/tasks/workflow.xml` (modify)
+
+Add Step 0 before existing Step 1:
+
+```xml
+<step n="0" title="Initialize Scope Context" critical="true">
+  <substep n="0a" title="Check for Scope Requirement">
+    <action>Scan workflow.yaml for {scope} variable</action>
+    <action>If found → workflow requires scope</action>
+  </substep>
+
+  <substep n="0b" title="Resolve Scope">
+    <!-- Priority order: -->
+    <!-- 1. --scope argument from command -->
+    <!-- 2. Session context (if set) -->
+    <!-- 3. Prompt user to select/create -->
+  </substep>
+
+  <substep n="0c" title="Load Scope Context">
+    <action>Load scope config from scopes.yaml</action>
+    <action>Resolve scope paths</action>
+    <action>Load global project-context.md</action>
+    <action>Load scope project-context.md (if exists, merge)</action>
+    <action>Check for dependency updates (notify if pending)</action>
+  </substep>
+</step>
+```
+
+### 2.2 Module.yaml Updates
+
+**File:** `src/bmm/module.yaml` (modify)
+
+```yaml
+# BEFORE
+planning_artifacts:
+  default: "{output_folder}/planning-artifacts"
+  result: "{project-root}/{value}"
+
+# AFTER
+planning_artifacts:
+  default: "{output_folder}/{scope}/planning-artifacts"
+  result: "{project-root}/{value}"
+
+implementation_artifacts:
+  default: "{output_folder}/{scope}/implementation-artifacts"
+  result: "{project-root}/{value}"
+```
+
+### 2.3 Workflow.yaml Update Script
+
+**File:** `tools/cli/scripts/migrate-workflows.js`
+
+Updates for 22+ workflow files:
+
+1. Update `test_dir` variables to use `{output_folder}/{scope}/tests`
+2. Handle variations in path definitions
+3. Preserve `{config_source}:` references (they'll work via updated module.yaml)
+
+### 2.4 Agent Activation Updates
+
+**File:** `src/utility/agent-components/activation-steps.txt` (modify)
+
+```xml
+<step n="2">🚨 IMMEDIATE ACTION REQUIRED:
+    - Load {project-root}/_bmad/{{module}}/config.yaml
+    - Store: {user_name}, {communication_language}, {output_folder}
+    - NEW: Check if scope is set for session
+    - NEW: Load global project-context: {output_folder}/_shared/project-context.md
+    - NEW: Load scope project-context (if exists): {output_folder}/{scope}/project-context.md
+    - NEW: Merge contexts (scope extends global)
+</step>
+```
+
+### 2.5 invoke-workflow Scope Propagation
+
+**Modification to workflow.xml:**
+
+When `<invoke-workflow>` is encountered:
+
+1. Pass current `{scope}` as implicit parameter
+2. Child workflow inherits scope from parent
+3. Can be overridden with explicit `<param>scope: other</param>`
+
+---
+
+## Phase 3: Isolation & Locking
+
+> **Estimate:** 2-3 days
+
+### 3.1 ArtifactResolver
+
+**File:** `src/core/scope/artifact-resolver.js`
+
+```javascript
+class ArtifactResolver {
+  constructor(currentScope, basePath) {
+    this.currentScope = currentScope;
+    this.basePath = basePath;
+  }
+
+  // Read-any: Allow reading from any scope
+  canRead(path) {
+    return true; // All reads allowed
+  }
+
+  // Write-own: Only allow writing to current scope
+  canWrite(path) {
+    const targetScope = this.extractScopeFromPath(path);
+
+    if (targetScope === '_shared') {
+      throw new Error('Cannot write directly to _shared. Use: bmad scope sync-up');
+    }
+
+    if (targetScope !== this.currentScope) {
+      throw new Error(`Cannot write to scope '${targetScope}' while in scope '${this.currentScope}'`);
+    }
+
+    return true;
+  }
+
+  extractScopeFromPath(path) {
+    // Extract scope from path like _bmad-output/auth/...
+  }
+}
+```
+
+### 3.2 File Locking
+
+**File:** `src/core/scope/state-lock.js`
+
+```javascript
+const lockfile = require('proper-lockfile');
+
+class StateLock {
+  async withLock(filePath, operation) {
+    const release = await lockfile.lock(filePath, {
+      stale: 30000, // 30s stale timeout
+      retries: { retries: 10, minTimeout: 100, maxTimeout: 1000 },
+    });
+
+    try {
+      return await operation();
+    } finally {
+      await release();
+    }
+  }
+
+  // Optimistic locking with version field
+  async updateYamlWithVersion(filePath, modifier) {
+    return this.withLock(filePath, async () => {
+      const data = await this.readYaml(filePath);
+      const currentVersion = data._version || 0;
+
+      const modified = await modifier(data);
+      modified._version = currentVersion + 1;
+      modified._lastModified = new Date().toISOString();
+
+      await this.writeYaml(filePath, modified);
+      return modified;
+    });
+  }
+}
+```
+
+**Files requiring locking:**
+
+- `{scope}/implementation-artifacts/sprint-status.yaml`
+- `{scope}/planning-artifacts/bmm-workflow-status.yaml`
+- `_shared/` files during sync operations
+- `scopes.yaml` during scope CRUD
+
+### 3.3 Package.json Update
+
+Add dependency:
+
+```json
+{
+  "dependencies": {
+    "proper-lockfile": "^4.1.2"
+  }
+}
+```
+
+---
+
+## Phase 4: Sync System
+
+> **Estimate:** 3-4 days
+
+### 4.1 Sync-Up (Promote to Shared)
+
+**Command:** `bmad scope sync-up <scope>`
+
+**Logic:**
+
+1. Identify promotable artifacts (configurable patterns)
+2. Check for conflicts with existing shared files
+3. Copy to `_shared/` with attribution metadata
+4. Log event for dependent scope notification
+
+**Metadata added to promoted files:**
+
+```yaml
+# _shared/architecture/auth-api.md.meta
+source_scope: auth
+promoted_at: '2026-01-21T10:00:00Z'
+original_hash: abc123
+version: 1
+```
+
+### 4.2 Sync-Down (Pull from Shared)
+
+**Command:** `bmad scope sync-down <scope>`
+
+**Logic:**
+
+1. Find shared updates since last sync
+2. Compare with local copies (if any)
+3. Handle conflicts (prompt user for resolution)
+4. Copy to scope directory
+5. Update last-sync timestamp
+
+### 4.3 Conflict Resolution
+
+**Options when conflict detected:**
+
+1. Keep local (overwrite shared)
+2. Keep shared (discard local)
+3. Merge (3-way diff if possible)
+4. Skip this file
+
+---
+
+## Phase 5: Event System
+
+> **Estimate:** 2 days
+
+### 5.1 Event Log Structure
+
+**File:** `_bmad/_events/event-log.yaml`
+
+```yaml
+version: 1
+events:
+  - id: evt_001
+    type: artifact_created
+    scope: auth
+    artifact: planning-artifacts/prd.md
+    timestamp: '2026-01-21T10:30:00Z'
+
+  - id: evt_002
+    type: artifact_promoted
+    scope: auth
+    artifact: architecture.md
+    shared_path: _shared/auth/architecture.md
+    timestamp: '2026-01-21T11:00:00Z'
+```
+
+### 5.2 Subscriptions
+
+**File:** `_bmad/_events/subscriptions.yaml`
+
+```yaml
+subscriptions:
+  payments:
+    watch:
+      - scope: auth
+        patterns: ['contracts/*', 'architecture.md']
+    notify: true
+```
+
+### 5.3 Notification on Activation
+
+When agent/workflow activates with scope:
+
+1. Check subscriptions for this scope
+2. Find events since last activity
+3. Display pending updates (if any)
+4. Suggest `bmad scope sync-down` if updates available
+
+---
+
+## Phase 6: IDE Integration & Documentation
+
+> **Estimate:** 2-3 days
+
+### 6.1 IDE Command Generators
+
+**File:** `tools/cli/installers/lib/ide/shared/scope-aware-command.js`
+
+Updates to workflow-command-template.md:
+
+```markdown
+### Scope Resolution
+
+This workflow requires a scope. Before proceeding:
+
+1. Check for --scope argument (e.g., `/create-story --scope auth`)
+2. Check session context for active scope
+3. If none, prompt user to select/create scope
+
+Store selected scope for session.
+```
+
+### 6.2 Session-Sticky Scope
+
+**Mechanism:** File-based `.bmad-scope` in project root
+
+```yaml
+# .bmad-scope (gitignored)
+active_scope: auth
+set_at: '2026-01-21T10:00:00Z'
+```
+
+### 6.3 Agent Menu Updates
+
+Add `scope_required` attribute:
+
+```yaml
+menu:
+  - trigger: 'prd'
+    workflow: '...'
+    scope_required: true # Enforce scope for this menu item
+```
+
+### 6.4 Documentation
+
+Files to create:
+
+1. `docs/multi-scope-guide.md` - User guide
+2. `docs/migration-guide.md` - Upgrading existing installations
+3. Update README with multi-scope overview
+
+---
+
+## Risk Mitigation
+
+| Risk                            | Mitigation                                       |
+| ------------------------------- | ------------------------------------------------ |
+| Breaking existing installations | Auto-migration with backup, rollback capability  |
+| Parallel write conflicts        | File locking + optimistic versioning             |
+| Cross-scope data corruption     | Write isolation enforcement in ArtifactResolver  |
+| Complex merge conflicts         | Clear conflict resolution UI + skip option       |
+| IDE compatibility               | Test with all supported IDEs, graceful fallbacks |
+| Performance with many scopes    | Lazy loading, scope caching                      |
+
+---

+
+## Implementation Order
+
+```
+Phase 0 ─────► Phase 1 ─────► Phase 2 ─────► Phase 3 ─────► Phase 4 ─────► Phase 5 ─────► Phase 6

+```
+
+**Critical Path:** Phase 0 → Phase 1 → Phase 2.1 → Phase 2.2 → Phase 3.1
+
+MVP can be achieved with Phases 0-3 (isolation working, no sync/events yet).

+- **contracts/** - Integration contracts and APIs between scopes
+- **principles/** - Architecture principles and design patterns
+- **architecture/** - High-level architecture documents
+- **project-context.md** - Global project context (the "bible")
+
+## Purpose
+
+The shared layer enables:
+- Cross-scope integration without tight coupling
+- Consistent architecture patterns across scopes
+- Centralized project context and principles
+- Dependency management through contracts
+
+## Usage
+
+1. **Reading**: All scopes can read from \`_shared/\`
+2. **Writing**: Use \`bmad scope sync-up <scope>\` to promote artifacts
+3. **Syncing**: Use \`bmad scope sync-down <scope>\` to pull updates
+
+## Best Practices
+
+- Keep contracts focused and minimal
+- Document all shared artifacts clearly
+- Version shared artifacts when making breaking changes
+- Use sync commands rather than manual edits

+2. **Load context**: If scope is active, load both:
+   - Global context: `_bmad-output/_shared/project-context.md`

+3. **Merge contexts**: Scope-specific context extends/overrides global
+4. **Menu items with `scope_required: true`**: Prompt for scope before executing
+
+For menu items that produce artifacts, ensure they go to the active scope's directory.

-IT IS CRITICAL THAT YOU FOLLOW THIS COMMAND: LOAD the FULL @{{workflow_path}}, READ its entire contents and follow its directions exactly!
+IT IS CRITICAL THAT YOU FOLLOW THESE STEPS IN ORDER:
+
+<scope-resolution CRITICAL="true">
+## Step 0: Resolve Scope Context BEFORE Workflow Execution
+
+The workflow file will instruct you to load config.yaml. BEFORE following those instructions:
+
+### 0a. Check for Active Scope
+1. Check for `.bmad-scope` file in {project-root}
+2. If exists, read the `active_scope` value and store as {scope}
+3. If `.bmad-scope` does not exist, skip to Step 1 (backward compatible, no scope)
+
+### 0b. Override Config Paths (CRITICAL - if scope is set)
+After loading config.yaml but BEFORE using any paths, you MUST override these variables:
+
+```
+{scope_path} = {output_folder}/{scope}
+{planning_artifacts} = {scope_path}/planning-artifacts
+{implementation_artifacts} = {scope_path}/implementation-artifacts
+{scope_tests} = {scope_path}/tests
+```
+
+**Example:** If config.yaml has `output_folder: "_bmad-output"` and scope is "auth":
+- {scope_path} = `_bmad-output/auth`
+- {planning_artifacts} = `_bmad-output/auth/planning-artifacts`
+- {implementation_artifacts} = `_bmad-output/auth/implementation-artifacts`
+
+**WARNING:** Config.yaml contains pre-resolved static paths. You MUST override them with the scope-aware paths above. DO NOT use the config.yaml values directly for these variables when a scope is active.
+
+### 0c. Load Scope Context
+If scope is set:
+- Load global context: `{output_folder}/_shared/project-context.md`
+- Load scope context if exists: `{scope_path}/project-context.md`
+- Merge: scope-specific content extends/overrides global
+</scope-resolution>
+
+## Step 1: Execute Workflow
+
+NOW: LOAD the FULL @{{workflow_path}}, READ its entire contents and follow its directions exactly!
+
+When the workflow instructs you to use `{planning_artifacts}` or `{implementation_artifacts}`, use YOUR OVERRIDDEN VALUES from Step 0b, not the static config.yaml values.
