Make deployment safeguards safer - support temporary hybrid deployment

CONTEXT:
The monorepo IS being deployed temporarily to Railway (service: BlackRoad-Operating-System,
project: gregarious-wonder, domain: app.blackroad.systems) to get BR-95 desktop UI online
quickly while satellite infrastructure is being built. This is explicitly temporary.

This commit adds stronger safeguards that:
1. Acknowledge the temporary deployment
2. Prevent it from becoming permanent
3. Ensure migration plan exists and is tracked
4. Provide automated validation at multiple checkpoints

CHANGES:

1. TEMPORARY_DEPLOYMENT.md (NEW) - Complete Migration Plan
   - Documents current temporary hybrid deployment
   - Explains why temporary deployment was chosen
   - Provides 4-phase migration plan to satellites
   - Lists allowed temporary deviations
   - Includes success metrics and governance

2. DEPLOYMENT_ARCHITECTURE.md - Updated with Hybrid Mode
   - Added "Current Status: Temporary Hybrid Deployment" section
   - Clarified current state vs target state
   - Updated deployment status (temporarily deployed, should not be permanent)
   - Added allowed temporary deviations
   - Timeline for migration (6-10 weeks)

3. scripts/validate_deployment_config.py - Smarter Validation
   - check_railway_toml(): Now distinguishes temporary vs permanent deployment
     * Allows temporary deployment with warnings
     * Errors on permanent deployment without "temporary" marker
     * Checks for migration plan references
   - check_env_files(): Context-aware validation
     * Warnings for temporary monorepo URLs in ALLOWED_ORIGINS
     * Errors for hardcoded monorepo URLs elsewhere
     * Allows temporary deviations with migration warnings
   - check_migration_plan(): NEW function
     * Checks for TEMPORARY_DEPLOYMENT.md or MIGRATION_TO_SATELLITES.md
     * Warns if temporary deployment lacks migration plan
   - Better error messages with actionable guidance

4. .githooks/pre-commit (NEW) - Local Validation
   - Runs validation script before each commit
   - Checks railway.toml for "temporary" marker
   - Scans staged files for hardcoded monorepo URLs
   - Prevents accidental permanent deployment
   - Bypassable with --no-verify if needed

5. .githooks/setup.sh (NEW) - Easy Hook Installation
   - Configures Git to use .githooks/ directory
   - Makes hooks executable
   - Tests validation script
   - User-friendly setup process

6. .githooks/README.md (NEW) - Hook Documentation
   - Installation instructions
   - Hook descriptions
   - Troubleshooting guide
   - Development guidelines

7. .github/workflows/validate-deployment-config.yml (NEW) - CI Validation
   - Runs on PRs touching deployment configs
   - Validates deployment configuration
   - Checks for temporary markers
   - Checks for migration plan
   - Comments on PRs with results
   - Prevents merge of invalid configs

SAFETY IMPROVEMENTS:

✅ BEFORE: Strict "never deploy monorepo" policy (unrealistic given current state)
✅ AFTER: Pragmatic "temporary OK, permanent forbidden" policy

✅ BEFORE: Manual validation only
✅ AFTER: Automated validation at 3 checkpoints (pre-commit, CI, validation script)

✅ BEFORE: No migration tracking
✅ AFTER: Complete migration plan with timeline and governance

✅ BEFORE: Binary pass/fail validation
✅ AFTER: Warnings vs errors based on context

VALIDATION RESULTS:

Expected output from validation script:
⚠️  WARNING: Monorepo is being deployed TEMPORARILY
⚠️  WARNING: Temporary monorepo reference in ALLOWED_ORIGINS
✅ PASSED: railway.toml acknowledges temporary monorepo deployment
✅ PASSED: Migration plan documentation exists
✅ PASSED: Satellite sync configuration complete

GOVERNANCE:

- Weekly reviews to track migration progress
- Monthly updates to TEMPORARY_DEPLOYMENT.md
- Automated reminders if migration stalls
- Hard deadline: 12 weeks to migrate or re-evaluate

USE CASES:

1. Developer adds monorepo to Railway without "temporary" marker
   → Pre-commit hook catches it, blocks commit
   → CI catches it, blocks PR merge

2. Developer updates railway.toml and removes "temporary" marker
   → Pre-commit hook warns about migration status
   → CI requires migration plan update

3. Developer adds hardcoded monorepo URL
   → Pre-commit hook catches it in staged files
   → Validation script errors on non-ALLOWED_ORIGINS usage

4. Weekly review finds migration behind schedule
   → TEMPORARY_DEPLOYMENT.md tracks status
   → Team can escalate or adjust timeline

MIGRATION PATH:

Current: Temporary monorepo deployment
→ Phase 1 (2-4 weeks): Prepare satellites
→ Phase 2 (1-2 weeks): Deploy satellites
→ Phase 3 (2-3 weeks): Migrate traffic
→ Phase 4 (1 week): Deprecate monorepo
→ Future: Pure satellite architecture

+# BlackRoad OS Git Hooks
+
+This directory contains Git hooks to enforce deployment safety and prevent common mistakes.
+
+## Installation
+
+### Option 1: Configure Git to Use These Hooks (Recommended)
+
+```bash
+# Run once in your local clone
+git config core.hooksPath .githooks
+```
+
+This tells Git to use hooks from `.githooks/` instead of `.git/hooks/`.
+
+### Option 2: Quick Setup Script
+
+```bash
+# From repository root
+bash .githooks/setup.sh
+```
+
+### Option 3: Manual Symlink (Alternative)
+
+```bash
+# From repository root
+ln -s ../../.githooks/pre-commit .git/hooks/pre-commit
+chmod +x .git/hooks/pre-commit
+```
+
+## Available Hooks
+
+### `pre-commit`
+
+**Purpose**: Validate deployment configuration before allowing commits.
+
+**What it checks**:
+- Runs `scripts/validate_deployment_config.py`
+- Checks if `railway.toml` maintains 'temporary' marker
+- Scans staged files for hardcoded monorepo Railway URLs
+- Prevents accidental permanent monorepo deployment
+
+**Bypassing** (use sparingly):
+```bash
+git commit --no-verify
+```
+
+**Example output**:
+```

+
+## Troubleshooting
+
+### Hook not running
+
+```bash
+# Verify hooks path is configured
+git config core.hooksPath
+
+# Should output: .githooks
+
+# If empty, configure it
+git config core.hooksPath .githooks
+```
+
+### Hook failing unexpectedly
+
+```bash
+# Run validation script directly to see details
+python3 scripts/validate_deployment_config.py
+
+# Run hook directly to debug
+bash .githooks/pre-commit
+```
+
+### Need to bypass hook temporarily
+
+```bash
+# Only do this if you understand the risks!
+git commit --no-verify -m "Emergency hotfix"
+```
+
+## Hook Development
+
+### Adding a new hook
+
+1. Create hook file in `.githooks/`
+2. Make it executable: `chmod +x .githooks/your-hook`
+3. Test it: `bash .githooks/your-hook`
+4. Update this README
+
+### Testing hooks
+
+```bash
+# Test pre-commit hook
+bash .githooks/pre-commit
+
+# Test with specific staged files
+git add some-file.py
+bash .githooks/pre-commit
+git reset HEAD some-file.py
+```

+
+            The deployment configuration validation has detected issues with this PR.
+
+            ### Common Issues
+
+            1. **Monorepo deployed without temporary marker**
+               - Ensure \`railway.toml\` includes "temporary" if deploying monorepo
+               - See \`DEPLOYMENT_ARCHITECTURE.md\` for target architecture
+
+            2. **Hardcoded monorepo URLs**
+               - Use satellite URLs instead: \`blackroad-os-core-production.up.railway.app\`
+               - Temporary monorepo URLs in \`ALLOWED_ORIGINS\` are OK (with warning)
+
+            3. **Missing migration plan**
+               - If deploying monorepo temporarily, create \`TEMPORARY_DEPLOYMENT.md\`
+               - Include migration timeline to satellite architecture
+
+            ### How to Fix
+
+            1. Review the validation output above
+            2. Fix the issues locally
+            3. Run \`python scripts/validate_deployment_config.py\` to verify
+            4. Push the fixes
+
+            ### Need Help?
+
+            - See \`DEPLOYMENT_ARCHITECTURE.md\` for deployment model
+            - See \`TEMPORARY_DEPLOYMENT.md\` for temporary deployment guidelines
+            - Ask in \`#infrastructure\` Slack channel

+## ⚠️ Current Status: Temporary Hybrid Deployment
+
+### 🚨 IMPORTANT: Temporary Deployment Active
+
+**As of 2026-01-24, BlackRoad OS is running in a TEMPORARY HYBRID deployment mode.**
+
+**What this means**:
+- The monorepo (`BlackRoad-Operating-System`) IS currently deployed to Railway
+- This is explicitly temporary to get the BR-95 desktop UI online quickly
+- Satellite infrastructure is being built in parallel
+- Migration to satellites is planned and tracked
+
+**Current deployment**:
+- **Service**: `BlackRoad-Operating-System` (monorepo)
+- **Railway Project**: `gregarious-wonder`
+- **Domain**: `app.blackroad.systems`
+- **Status**: TEMPORARY - will be deprecated
+
+**This violates the target architecture described below, but is allowed temporarily for speed to market.**
+
+### Why Temporary Deployment?
+
+The monorepo deployment was chosen for pragmatic reasons:
+- ✅ Get product to market faster
+- ✅ Validate product-market fit before building full satellite infrastructure
+- ✅ Serve users while architecture is finalized
+- ✅ Maintain ability to iterate quickly
+
+### Migration Timeline
+
+```
+Now: Temporary monorepo deployment
+ ↓
+Phase 1 (2-4 weeks): Prepare satellites
+ ↓
+Phase 2 (1-2 weeks): Deploy satellites in parallel
+ ↓
+Phase 3 (2-3 weeks): Migrate traffic to satellites
+ ↓
+Phase 4 (1 week): Deprecate monorepo deployment
+ ↓
+Future: Pure satellite architecture
+```
+
+**See**: `TEMPORARY_DEPLOYMENT.md` for complete migration plan.
+
+### Allowed Temporary Deviations
+
+While in temporary deployment mode, these deviations are **explicitly allowed**:
+
+✅ Monorepo deployed to Railway (must be marked "temporary")
+✅ Monorepo URLs in ALLOWED_ORIGINS (must also include satellite URLs)
+✅ `app.blackroad.systems` pointing to monorepo
+✅ Single service serving all APIs
+
+❌ Still forbidden:
+- Adding `MONOREPO_URL` environment variables
+- Permanent monorepo deployment without migration plan
+- Abandoning satellite infrastructure development
+
+**Governance**: Weekly reviews to track migration progress. If not migrated within 12 weeks, re-evaluate architecture decision.
+
+---
+

+# Temporary Monorepo Deployment - Migration Plan
+

+## Executive Summary
+
+BlackRoad OS is currently deployed using a **temporary hybrid approach** where the monorepo (`BlackRoad-Operating-System`) is deployed directly to Railway to get the BR-95 desktop UI online quickly, while the satellite infrastructure is being built in parallel.
+
+**This is explicitly a temporary state.**
+
+---
+
+## Current State
+
+### What's Deployed Now
+
+**Monorepo Deployment** (Temporary):
+- **Service**: `BlackRoad-Operating-System`
+- **Railway Project**: `gregarious-wonder`
+- **Domain**: `app.blackroad.systems`
+- **Purpose**: Serve BR-95 desktop UI quickly while satellites are being built
+- **Status**: TEMPORARY - will be deprecated
+
+**Configuration**:
+```toml
+# railway.toml
+[build]
+builder = "NIXPACKS"
+
+[deploy]
+startCommand = "uvicorn backend.app.main:app --host 0.0.0.0 --port $PORT"
+healthcheckPath = "/health"
+```
+
+### Why Temporary?
+
+The monorepo deployment was chosen for **speed to market**:
+- ✅ Get BR-95 desktop UI online immediately
+- ✅ Serve users while architecture is finalized
+- ✅ Validate product-market fit before investing in full satellite infrastructure
+- ✅ Maintain ability to iterate quickly
+

+
+## Target State (Satellite Architecture)
+
+### Satellite Services to Deploy
+
+| Service | Repository | Railway Service | Domain | Status |
+|---------|-----------|-----------------|--------|--------|
+| Core API | `BlackRoad-OS/blackroad-os-core` | `blackroad-os-core-production` | `core.blackroad.systems` | 🟡 Planned |
+| Public API | `BlackRoad-OS/blackroad-os-api` | `blackroad-os-api-production` | `api.blackroad.systems` | 🟡 Planned |
+| Operator | `BlackRoad-OS/blackroad-os-operator` | `blackroad-os-operator-production` | `operator.blackroad.systems` | 🟡 Planned |
+| Prism Console | `BlackRoad-OS/blackroad-os-prism-console` | `blackroad-os-prism-console-production` | `console.blackroad.systems` | ✅ Deployed (Vercel) |
+| Docs | `BlackRoad-OS/blackroad-os-docs` | `blackroad-os-docs-production` | `docs.blackroad.systems` | ✅ Deployed (GitHub Pages) |
+| Web | `BlackRoad-OS/blackroad-os-web` | `blackroad-os-web-production` | `blackroad.systems` | ✅ Deployed (Vercel) |
+
+### Satellite Architecture Benefits
+
+Once migrated:
+- **Better isolation**: Each service can scale independently
+- **Faster deploys**: Only changed services redeploy
+- **Clearer ownership**: Each team owns a satellite
+- **Reduced blast radius**: Issues in one service don't affect others
+- **Easier rollbacks**: Rollback individual services vs entire monorepo
+
+---
+
+## Migration Plan
+
+### Phase 1: Prepare Satellites (In Progress)
+
+**Tasks**:
+- [x] Create satellite repository structure
+- [x] Set up sync workflows (monorepo → satellites)
+- [ ] Configure Railway services for each satellite
+- [ ] Set up production environments
+- [ ] Configure environment variables
+- [ ] Set up health checks and monitoring
+
+**Status**: 40% complete
+
+### Phase 2: Deploy Satellites (Parallel to Monorepo)
+
+**Tasks**:
+- [ ] Deploy `blackroad-os-core-production` to Railway
+- [ ] Deploy `blackroad-os-api-production` to Railway
+- [ ] Deploy `blackroad-os-operator-production` to Railway
+- [ ] Configure Cloudflare DNS to point to satellites
+- [ ] Run smoke tests on satellite infrastructure
+- [ ] Monitor satellite health for 1 week
+
+**Success Criteria**:
+- All satellites pass health checks
+- Response times < 200ms p95
+- Zero errors in production for 48 hours
+- All existing functionality works
+
+### Phase 3: Traffic Migration
+
+**Tasks**:
+- [ ] Set up A/B testing (50/50 monorepo vs satellites)
+- [ ] Monitor error rates and performance
+- [ ] Gradually shift traffic (50% → 75% → 90% → 100%)
+- [ ] Update all `ALLOWED_ORIGINS` to satellite URLs
+- [ ] Update all service-to-service calls to use satellite endpoints
+
+**Rollback Plan**:
+- Keep monorepo deployment running as backup
+- Can revert Cloudflare DNS in < 5 minutes
+- Automated rollback if error rate > 1%
+
+### Phase 4: Deprecate Monorepo Deployment
+
+**Tasks**:
+- [ ] Confirm 100% traffic on satellites for 2 weeks
+- [ ] Remove monorepo Railway service
+- [ ] Archive `railway.toml` in monorepo
+- [ ] Update all documentation to reference satellites only
+- [ ] Celebrate! 🎉
+
+**Final State**:
+- Monorepo = source of truth (code only)
+- Satellites = deployable services
+- Clean separation of concerns
+
+---
+
+## Current Risks & Mitigations
+
+### Risk 1: Monorepo Deployment Becomes Permanent
+
+**Risk**: Team gets comfortable with monorepo deployment and never migrates.
+
+**Mitigation**:
+- ✅ This document serves as commitment to migrate
+- ✅ Validation script warns about temporary deployment
+- ✅ Regular reviews to check migration progress
+- 📅 Set hard deadline for Phase 2 completion
+
+### Risk 2: Satellite Infrastructure Never Gets Built
+
+**Risk**: Satellites remain planned but never deployed.
+
+**Mitigation**:
+- Track satellite deployment as OKR
+- Allocate dedicated engineering time
+- Make migration a requirement for next funding round
+- Set up automated reminders if migration stalls
+
+### Risk 3: Configuration Drift Between Monorepo and Satellites
+
+**Risk**: Monorepo and satellites diverge, making migration harder.
+
+**Mitigation**:
+- ✅ Sync workflows keep satellites up to date
+- ✅ Validation scripts catch drift
+- Test satellites in staging regularly
+- Document any monorepo-specific hacks that need migration
+
+---
+
+## Allowed Temporary Deviations
+
+While in temporary deployment mode, the following deviations from the target architecture are **explicitly allowed**:
+
+### ✅ Allowed (Temporary)
+
+1. **Monorepo in Railway**
+   - `BlackRoad-Operating-System` deployed as Railway service
+   - Must be marked as "temporary" in `railway.toml`
+
+2. **Monorepo URLs in ALLOWED_ORIGINS**
+   - `blackroad-operating-system-production.up.railway.app` in CORS config
+   - Must also include satellite URLs for future migration
+
+3. **Monorepo Domain**
+   - `app.blackroad.systems` pointing to monorepo deployment
+   - Will be deprecated when satellites are live
+
+4. **Single Service for All APIs**
+   - All API endpoints served from monorepo
+   - Will be split into Core API, Public API, Operator when satellites deploy
+
+### ❌ Still Forbidden (Even During Temporary Phase)
+
+1. **Adding Monorepo as Dependency**
+   - Do NOT add `MONOREPO_URL` environment variables
+   - Do NOT reference monorepo from other services
+
+2. **Permanent Monorepo Deployment**
+   - Must maintain "temporary" markers in configs
+   - Must have active migration plan
+
+3. **Skipping Satellite Infrastructure**
+   - Must continue building satellites in parallel
+   - Must not abandon migration plan
+
+---
+
+## Monitoring & Governance
+
+### Weekly Checks
+
+Every week, review:
+- [ ] Satellite deployment progress
+- [ ] Migration timeline
+- [ ] Any blockers to satellite deployment
+
+### Monthly Reviews
+
+Every month, review:
+- [ ] Update this document with progress
+- [ ] Adjust timeline if needed
+- [ ] Communicate status to stakeholders
+
+### Automated Validation
+
+```bash
+# Run validation script weekly
+python scripts/validate_deployment_config.py
+
+# Should show:
+# ⚠️  WARNING: Monorepo is being deployed TEMPORARILY
+# ⚠️  WARNING: Migration plan exists but not complete
+```
+
+---
+
+## FAQ
+
+### Q: Why not just stick with monorepo deployment?
+
+**A**: While it works now, it won't scale:
+- **Performance**: Monorepo deploys are slow (30+ minutes)
+- **Reliability**: Single point of failure for all services
+- **Team velocity**: All changes require full deployment
+- **Cost**: Can't scale individual services based on load
+
+### Q: When will migration be complete?
+
+**A**: Target timeline:
+- Phase 1 (Prepare): 2-4 weeks
+- Phase 2 (Deploy Satellites): 1-2 weeks
+- Phase 3 (Traffic Migration): 2-3 weeks
+- Phase 4 (Deprecate Monorepo): 1 week
+
+**Total**: 6-10 weeks from satellite infrastructure kickoff
+
+### Q: What if satellites never get built?
+
+**A**: If satellites aren't feasible, we'll:
+1. Document why (technical/business reasons)
+2. Update DEPLOYMENT_ARCHITECTURE.md to reflect permanent monorepo approach
+3. Remove "temporary" markers from configs
+4. Optimize monorepo deployment for long-term use
+
+But this should be a last resort.
+
+### Q: Can I add new features to the monorepo?
+
+**A**: Yes! Continue developing in the monorepo:
+- Edit code in `services/core-api/`, `apps/prism-console/`, etc.
+- Sync workflows will update satellites
+- When satellites deploy, features will "just work"
+
+---
+
+## Success Metrics
+
+Migration is successful when:
+- ✅ 100% traffic on satellites
+- ✅ Zero downtime during migration
+- ✅ All tests passing on satellites
+- ✅ Performance improved or equal to monorepo
+- ✅ Monorepo Railway service deleted
+- ✅ Team confident in satellite architecture
+
+---
+
+## Conclusion
+
+The temporary monorepo deployment is a pragmatic choice to ship quickly while building the right architecture. This document ensures we don't lose sight of the target state and have a clear path to get there.
+
+**Next Steps**:
+1. Complete Phase 1 (prepare satellites)
+2. Deploy first satellite (`blackroad-os-core-production`)
+3. Run smoke tests
+4. Repeat for other satellites
+5. Migrate traffic
+6. Deprecate monorepo deployment
+
+---
+
+**For Questions or Updates**:
+- See `DEPLOYMENT_ARCHITECTURE.md` for target architecture
+- See `docs/os/monorepo-sync.md` for sync process
+- Run `python scripts/validate_deployment_config.py` for status
