IP + Royalty Flow

Otetto Homes, Living Canvas, and Ground Projects each pay a royalty per unit/m2 to Yieldtech, which holds all group IP.

Investment Structure

Yieldtech raises capital for group equity. Living Canvas raises separately — investors get LC equity direct. OH + GP do not raise directly (one combined raise to split later).

Project Combinations

OH designs + LC panels + GP builds = Otetto Homes brand. GP builds without OH = Ground Projects brand. LC panels to third-party builder = Living Canvas brand.

⚠

CRITICAL PATH — B6.5: A2A transport (Atlas to Patrick/Mason protocol) is not yet built. All cross-stack automation waits for this. Layer 6 A2A transport is the blocker.

OpenClaw Gateway live on Atlas Mini (port 18789). A2A protocol (Atlas to Patrick/Mason) not yet built. B6.5 is the single biggest blocker in the stack. Cross-stack automation between Christo's agents and Harro's agents requires this. Everything that depends on cross-stack coordination waits here.

B6.5

A2A Transport Hardening

Atlas to Patrick/Mason protocol must be built and tested before any cross-stack automation is possible. Blocks: LC raise coordination between stacks, Ground Projects ops bridging (Mason), all joint Christo+Harro workflows. This is the single most important unbuilt component in the OS. Every workflow that spans the two stacks waits here.

Cognee unified graph + vector retrieval. Replaces current Chroma + QMD interim. Requires B6.5 for cross-stack knowledge queries. Architecture confirmed, deployment not started.
