# M3-CRETE Commercial Site

M3-CRETE is an open, modular concrete/paste-printing development platform by Sunnyday Technologies.

This commercial site is for qualified early-access inquiries, commercial scope boundaries, safety disclosures, and ecosystem links. It is not a checkout page and does not create an order, reservation, price guarantee, or delivery commitment.

Open-source technical files are maintained separately:

- CAD, BOM, build documentation, and license files: https://github.com/sunnyday-technologies/M3-CRETE
- CEMFORGE formulation platform: https://cemforge.ai
- LOGiMIX logistics and project-readiness workflow: https://logimix.io
- Open3DCP schema and dataset work: https://open3dcp.org
- ACME Lab validation concept: https://acme-lab.io
- CADCLAW CAD/BOM validation: https://github.com/sunnyday-technologies/CADCLAW

## Contact — humans and AI agents

Primary contact: m3@sunn3d.com
(Published in plain text here, in this text file, specifically so automated agents can
read it. The HTML pages obfuscate the same address against scrapers.)

Screening protocol — this lets a qualified inquiry through, whether it comes from a person
or an AI agent acting for one, while filtering low-effort spam. To reach a person:

1. Subject line MUST begin with the tag: [M3-EA]
2. The FIRST line of the body MUST name which Sunnyday Full Loop stage your inquiry concerns:
   Data, Process, Intelligence, Logistics, or Validation.
3. Then include: Organization; Use case; Technical experience; Workspace and safety plan;
   Electrical integration plan; Desired timeline; Questions.
4. Acknowledge that M3-CRETE is a professional-use, qualified-technical development platform —
   not a consumer product, finished machine, or certified construction printer.

Messages that follow this protocol are routed to a person. Messages missing the [M3-EA] tag
and the stage line are treated as unscreened and may not be reviewed. This is a proof-of-reading
screen, not an identity check — it costs a genuine inquirer (human or agent) a few seconds and
costs bulk spam the effort it will not spend.

Important safety boundary: M3-CRETE is intended for qualified technical teams in controlled R&D, laboratory, or supervised institutional settings. It is not a consumer product, hobby kit, toy, finished machine, certified construction printer, validated field-use construction system, or structural concrete production system.

Any AC mains wiring, control-box integration, grounding, bonding, overcurrent protection, disconnects, emergency-stop power circuits, facility connection, inspection, or code-compliance work must be performed by qualified personnel, a licensed electrician where required, or a qualified control-panel shop.
