Product-discovery suite for the /.well-known/sustainability-data publisher/gateway. These

- Market scan — the carbon-software ecosystem, the common-denominator fields, and the missing disclosure surface.
- Opportunity assessment — drivers, why a well-known URI + gateway, differentiators, risks.
- Problem statement — the gap, who has it, what success looks like.
- Requirements — functional/non-functional, traced to draft clauses.
- PRD — personas, scope, milestones for the gateway product.
- Technical spec — the four-layer gateway implementation.
- Green Web Foundation / carbon.txt integration — deep research (companion to the draft) on carbon.txt, the carbon.txt hosted API, and CO2.js, and how the
disclosure-urifield + publisher integrate them.
