## Key Findings Summary

### Critical Discovery
**Only `/tmp` has executable permissions** on StackCP shared hosting
- Home directory is `noexec` (cannot run binaries or compile native modules)
- Application code MUST be in `/tmp/navidocs/`
- Data (database, uploads) MUST be in `~/navidocs/`
- This fundamentally breaks standard deployment assumptions

### Architectural Blockers
1. **Repository structure**: Assumes single location for code + data
2. **Native modules**: Cannot compile in home directory
3. **Process management**: PM2/systemd assumptions may not work
4. **File persistence**: `/tmp` may be cleared on reboot
5. **Development workflow**: npm must be executed via wrapper

### Required Changes
1. **Code** (2-3 days): Path configuration, environment detection
2. **Operations** (1-2 days): Checkpoint scripts, health checks, backups
3. **Documentation** (1-2 days): Rewrite deployment guides
4. **Testing** (1 day): StackCP-specific scenarios

**Total**: 5-7 days for full StackCP adaptation

### Alternatives
1. **VPS Deployment** (1 day): Standard environment, $5-6/month
2. **Container Platform** (1 day): Modern deployment, $5-10/month
3. **Hybrid Approach** (3-4 days): Support both StackCP and standard

## Cost-Benefit Analysis

### StackCP Adaptation
- **Time**: 5-7 days development
- **Cost**: $0 new (using existing hosting)
- **Operational overhead**: Ongoing custom scripts
- **Technical debt**: Medium-High (StackCP-specific code)
- **Security risk**: Medium (code exposure in `/tmp`)

### VPS Alternative
- **Time**: 1 day development
- **Cost**: $6/month ($72/year)
- **Operational overhead**: Standard (PM2, systemd)
- **Technical debt**: Low (industry standard)
- **Security risk**: Low (standard practices)

**Savings with VPS**: $2,400-4,100 in Year 1 (considering developer time)

## Recommended Decision Path

### Step 1: Answer Key Questions (5 minutes)
Use `/home/setup/navidocs/STACKCP_QUICK_REFERENCE.md` section "Key Questions"

### Step 2: Evaluate Risks (10 minutes)
Review security and operational risks in Debate Brief

### Step 3: Choose Path (5 minutes)
- **Path A**: Full StackCP (only if hard requirement + acceptable risks)
- **Path B**: Hybrid (if learning value + time available)
- **Path C**: VPS (default recommendation)

### Step 4: Implement (1-7 days)
Follow implementation plan in chosen path

## For Immediate Use

### Starting the Debate
1. **Open**: `STACKCP_QUICK_REFERENCE.md` (shared screen)
2. **Reference**: `STACKCP_DEBATE_BRIEF.md` (for detailed questions)
3. **Backup**: `STACKCP_ARCHITECTURE_ANALYSIS.md` (for technical details)

### Decision Checklist
- [ ] Why StackCP? (cost, existing account, learning)
- [ ] Security acceptable? (code exposure, external services)
- [ ] Timeline? (1 day VPS vs 5-7 days StackCP)
- [ ] Long-term vision? (personal, startup, enterprise)
- [ ] Maintenance capacity? (solo, team, DevOps)

### After Decision
- [ ] Document chosen path in project README
- [ ] Update ARCHITECTURE-SUMMARY.md with constraints
- [ ] Create implementation task list
- [ ] Assign owner for implementation
- [ ] Set review milestones
