Phase 1: Proof of Concept

Status: Not Started Duration: 4-6 weeks Team Size: 3-4 engineers (2 Python, 1 Rust, 1 generalist) Prerequisites: Phase 0 complete Start Date: TBD Target Completion: TBD

Overview

Phase 1 builds the minimal viable OctoLLM system with core components: Reflex Layer, Orchestrator, and 2 Arms (Planner and Executor). This phase proves the architectural concept and establishes the foundation for all subsequent development.

Key Deliverables:

1. Reflex Layer (Rust) - <10ms preprocessing, PII detection, caching
2. Orchestrator MVP (Python) - Task planning, routing, execution
3. Planner Arm (Python) - Task decomposition with GPT-3.5
4. Executor Arm (Rust) - Sandboxed command execution
5. Docker Compose deployment - All services running locally
6. E2E tests and demo - Working task submission to completion

Success Criteria:

• ✅ All 4 components deployed and healthy
• ✅ E2E tests passing (>90% success rate)
• ✅ Latency targets met (P99 <30s for 2-step tasks)
• ✅ Security tests passing (no sandbox escapes)
• ✅ Demo video recorded (5 minutes)
• ✅ Documentation updated
