## ⚠️ POTENTIAL GAPS IDENTIFIED

### Gap 1: Security Headers (Low Priority)

**Audit Finding**:
> "Missing security headers documentation" - MCP server should include X-Content-Type-Options, X-Frame-Options, etc.

**Revised Plan**: Not explicitly mentioned in Phase 2 (MCP Server Rewrite)

**Recommendation**: Add to Phase 2 checklist:
```yaml
- [ ] Add security headers to MCP server:
  - [ ] X-Content-Type-Options: nosniff
  - [ ] X-Frame-Options: DENY
  - [ ] X-XSS-Protection: 1; mode=block
  - [ ] Strict-Transport-Security: max-age=31536000
  - [ ] Content-Security-Policy: default-src 'self'
```

**Priority**: Low (can be added during Phase 2 implementation)

---

### Gap 2: RBAC Model Details (Low Priority)

**Audit Finding**:
> "No principles of least privilege" - No permission model for different user types

**Revised Plan**: Phase 6 mentions "Document RBAC model (if applicable)" - minimal

**Recommendation**: Add RBAC implementation to Phase 0 or Phase 1:
```yaml
Phase 0: Security Hardening
- [ ] Implement role-based access control:
  - [ ] Define roles (admin, operator, viewer)
  - [ ] Define permissions for each role
  - [ ] Add role-based CLI command restrictions
  - [ ] Add RBAC to MCP server tools
```

**Priority**: Low (can defer to Phase 6 or v1.1)

---

### Gap 3: CLI Async/Sync Bridge

**Audit Finding**:
> "CLI synchronous calls to async methods" - If adapters are async, CLI commands need to handle this

**Revised Plan**: Phase 1 mentions "Update all adapter call sites to use await" but CLI not explicitly mentioned

**Current State**: Revised plan shows CLI commands as async:
```python
@app.command()
async def sweep(...):
```

**Potential Issue**: Typer doesn't natively support async commands

**Recommendation**: Verify async CLI pattern works or use asyncio.run():
```python
# Option 1: If Typer supports async
@app.command()
async def sweep(...):
    result = await adapter.execute(...)

# Option 2: Use asyncio.run
@app.command()
def sweep(...):
    result = asyncio.run(adapter.execute(...))
```

**Priority**: Medium (must resolve in Phase 1)

---

### Gap 4: LLM Provider Configuration Details

**Audit Finding**:
> "Missing LLM provider integration" - Adapters need actual LLM configuration

**Revised Plan**: Phase 3 includes "Add LLM provider configuration (OpenAI, Anthropic, Gemini)" but lacks details

**Recommendation**: Add specific implementation details to Phase 3:
```yaml
Phase 3: Adapter Implementation
Week 5-6: LangGraph Adapter
- [ ] Implement LLM provider factory:
  - [ ] OpenAI: GPT-4, GPT-3.5-turbo
  - [ ] Anthropic: Claude Sonnet, Claude Opus
  - [ ] Gemini: Gemini Pro, Gemini Ultra
- [ ] Add LLM configuration validation:
  - [ ] API key validation
  - [ ] Model availability check
  - [ ] Rate limit handling
- [ ] Add LLM fallback logic:
  - [ ] Primary provider failure
  - [ ] Automatic fallback to secondary
  - [ ] Circuit breaker per provider
```

**Priority**: Medium (important for Phase 3)

---

### Gap 5: Error Message Sanitization

**Audit Finding**:
> "Error messages leak sensitive information" - Task parameters could contain secrets

**Revised Plan**: Not explicitly mentioned

**Recommendation**: Add to Phase 0 or Phase 1:
```yaml
Phase 1: Foundation Fixes
- [ ] Implement error message sanitization:
  - [ ] Create sanitize_task() function
  - [ ] Redact API keys, passwords, tokens
  - [ ] Strip sensitive data from error details
  - [ ] Add debug mode flag for verbose errors
```

**Priority**: Medium (security best practice)

---

### Gap 6: Workflow Progress Reporting

**Audit Finding**:
> "Missing progress reporting" - No real-time updates for long-running workflows

**Revised Plan**: Phase 3 mentions "Add progress tracking (streaming updates)" but lacks details

**Recommendation**: Add specific implementation:
```yaml
Phase 3: Adapter Implementation
- [ ] Implement progress reporting:
  - [ ] Define ProgressUpdate schema
  - [ ] Add callback/async iterator pattern
  - [ ] Emit progress events (0%, 25%, 50%, 75%, 100%)
  - [ ] Display progress in CLI (progress bar)
  - [ ] Stream progress via MCP server
```

**Priority**: Low (nice-to-have for UX)

---

### Gap 7: Cancellation Token Pattern

**Audit Finding**:
> "Missing workflow cancellation" - No ability to cancel in-flight workflows

**Revised Plan**: Phase 3 mentions "timeout enforcement" but not cancellation

**Recommendation**: Add to Phase 3:
```yaml
Phase 3: Adapter Implementation
- [ ] Implement workflow cancellation:
  - [ ] Create CancellationToken class
  - [ ] Add cancel_workflow() to MCP tools
  - [ ] Check cancellation token in adapter loops
  - [ ] Graceful shutdown of in-flight operations
```

**Priority**: Low (can defer to v1.1)

---

### Gap 8: Configuration Setup Script

**Audit Finding**:
> "Missing configuration files" - Users have no reference configurations

**Revised Plan**: Phase 0 includes "Create example configuration templates" but no automation

**Recommendation**: Add setup wizard or init command:
```yaml
Phase 0: Security Hardening
- [ ] Create configuration setup wizard:
  - [ ] mahavishnu init command
  - [ ] Interactive config generation
  - [ ] Environment variable prompts
  - [ ] Secret generation (openssl rand)
  - [ ] Validation of generated config
```

**Priority**: Medium (improves developer experience)

---

### Gap 9: Dead Letter Queue Implementation

**Audit Finding**:
> "Missing dead letter queue" - No handling for permanently failed repos

**Revised Plan**: Phase 4 mentions "Implement dead letter queue" but lacks details

**Recommendation**: Add specific implementation:
```yaml
Phase 4: Production Features
- [ ] Implement dead letter queue (DLQ):
  - [ ] Define DLQ schema (repo, error, timestamp, retry_count)
  - [ ] Add dlq.yaml for persistent storage
  - [ ] Add retry_dlq() CLI command
  - [ ] Add purge_dlq() CLI command
  - [ ] Add list_dlq() CLI command
```

**Priority**: Medium (important for production)

---

### Gap 10: Backup/Restore Strategy

**Audit Finding**: Not explicitly in audit, but implied by "production readiness"

**Revised Plan**: Phase 6 mentions "Create rollback plan" but no backup strategy

**Recommendation**: Add to Phase 6:
```yaml
Phase 6: Production Readiness
- [ ] Define backup/restore strategy:
  - [ ] Backup configuration files
  - [ ] Backup Session-Buddy checkpoints
  - [ ] Backup dead letter queue
  - [ ] Document restore procedures
  - [ ] Test restore process
```

**Priority**: Low (operational procedure)

---
