Purpose Before Positioning: Coordinating local mutual aid and capacity through Context-First Ephemeral Routing.

The Community Application: Post Sheet

The community board for finding, sharing and connecting with people.

The Underlying Technology: Synchronicity

The coordination framework that connects needs, offers and shared context.

The Core Design Paradigm: Purpose Before Positioning

Our boards are built on Purpose Before Positioning—start with what you need, not just where you are.

The Network Architecture: Infrastructure-Agnostic Resource Mesh

The architecture for online and offline coordination across supported transports.

The Routing Algorithm: Context-First Ephemeral Routing

The internal method for matching people in ad-hoc spaces using shared context without requiring GPS.

Prototype capabilities

The current shared board uses authenticated HTTPS and edge persistence. Local planning can continue on the device. Physical offline device-to-device transport remains under development and has not been field-verified.

The S04 local loop test checks client-to-edge envelope hashing. Its receipt, “Edge envelope verification passed.”, does not certify delivery to another device.
