Cooren — Coordination Engine

Decision-as-a-Service API by McLeod Interactive Group LLC

---

What is Cooren?

Cooren is a backend Coordination Engine API that automates multi-party decision-making across any domain.

Whether a family choosing dinner or a logistics hub tendering a load — the bottleneck is always the same: the gap between request and decision.

Cooren closes that gap. Six endpoints. One complete decision loop. No UI required.

---

The Problem Cooren Solves

Every coordinated decision shares the same structure:

1. Someone defines options
2. Stakeholders signal preferences
3. An authority closes the loop

The infrastructure to do this reliably — auth, state management, tally logic, billing — gets rebuilt from scratch in every application that needs it. Cooren abstracts that infrastructure into a clean API so developers never build it again.

Core Architecture

Zero-Trust Auth

Single-use cryptographic participant tokens. Authority tokens gate session control. No passwords, no sessions.

Stateless Logic

Listen-Act-Close architecture. Each request is self-contained. Scales horizontally with zero session state.

Credit-as-a-Service

Stripe-native billing. Free tier included. Upgrade via API. Usage tracked per key, per operation.

The Decision Loop

# 1. Create a coordination session
POST /api/create_session.php
Authorization: Bearer cr_live_<key>
Body: { "title": "Where should we eat?" }

# 2. Load the options
POST /api/add_options.php
Body: { "session_id": "...", "options": ["Pizza", "Sushi", "Tacos"] }

# 3. Invite participants
POST /api/add_participants.php
Body: { "session_id": "...", "participants": ["alice@example.com"] }

# 4. Participants vote
POST /api/submit_signal.php
Body: { "token": "cr_pt_<participant_token>", "option_id": "..." }

# 5. Check the tally
GET /api/get_tally.php?session_id=...

# 6. Record the decision
POST /api/record_decision.php
Body: { "authority_token": "cr_at_<token>", "option_id": "..." }

Use Cases

Consumer Family or group decision apps. Dinner, movies, travel. Any multi-party choice with a human authority.

Logistics Load tendering with verified carrier acceptance. Instantaneous M2M consensus across dispatch nodes.

Enterprise Async decision workflows across time zones. No meetings. Stakeholders signal, authority closes.

Manufacturing Decentralized task allocation across machine nodes. Signal-driven orchestration without a central scheduler.

---

Proof of Concept

Cooren's coordination loop was extracted from Dinner Decider — a deployed consumer app available on Google Play and the Apple App Store. The decision loop powering family meal voting is the same primitive that powers any coordinated decision at any scale.

The loop is proven in production. Cooren exposes it as infrastructure.
