# Unified Architecture Redesign — Monaco Ocean Protection Challenge

> **Status**: Design specification (pre-implementation)
> **Date**: 2026-02-15
> **Scope**: Complete redesign of the round/pipeline system for multi-round competition management

---

## Overview

This document set specifies the architecture redesign for the MOPC platform's competition system. The core change eliminates the Track abstraction layer and renames Pipeline → **Competition**, Stage → **Round**, producing a flat, linear round sequence with typed configurations per round type.

The design supports the full Monaco 2026 competition flow: Intake → AI Filtering → Jury 1 Evaluation → Semifinal Submission → Jury 2 Evaluation + Special Awards → Mentoring → Live Finals (Jury 3) → Deliberation → Result Lock.

## Recommended Reading Order

1. **01 Architecture & Decisions** — understand the "why" and core decisions
2. **02 Data Model** — the schema that everything builds on
3. **03 Competition Flow** — how the 8 rounds work end-to-end
4. **04–07** — deep dives into specific subsystems (read as needed)
5. **08 Integration Matrix** — understand the blast radius across the platform
6. **09–10** — implementation and migration planning
7. **11–12** — quality and operational readiness
8. **13 Open Questions** — remaining decisions and governance

## Key Terminology

| Old Term | New Term | Notes |
|----------|----------|-------|
| Pipeline | **Competition** | Top-level competition round container |
| Stage | **Round** | Individual phase within a competition |
| Track | *(eliminated)* | Replaced by SpecialAward with routing modes |
| StageType | **RoundType** | INTAKE, FILTERING, EVALUATION, SUBMISSION, MENTORING, LIVE_FINAL, DELIBERATION |
| configJson | **Typed Config** | Per-round-type Zod-validated configuration |
| WinnerProposal | **DeliberationSession** | New deliberation voting model |
| WinnerApproval | **DeliberationVote** | Per-juror vote in deliberation |
| Confirmation | **Deliberation** | Deliberation IS the confirmation step |
