Puro.earth issues the certificate. EWP proves the task underneath it. Here's the honest seam.
In one plain sentence: Puro.earth is a carbon-removal standard AND registry, it writes the methodology rules for biochar and seven other durable-CDR pathways, and its Puro Registry has issued 1.78M+ tonnes of CO2 Removal Certificates (CORCs), and this page is an unaffiliated, evidence-first look at where a much lighter proof layer (ours) might honestly plug in as upstream field evidence, not a claim that it already does.
Relationship, stated plainlyEcoWealth has no relationship of any kind with Puro.earth: no contract, no integration, no contact, nothing sent. Independent, unsolicited, passive desk research, staged locally and not shared anywhere.

The whole thing, plainly
Puro.earth writes the rules and runs a real, daily-updated registry for durable carbon removal, 1.78M+ tonnes issued, credited in full.
We already built the lighter piece it doesn't have, free to see: a proof receipt (photo + GPS + signature) for the field task underneath a certificate, not a substitute for their registry, just cheap upstream evidence.
The ask: none. This is a courtesy observation, not a pitch.
4 facts from the public record
Credit-first, because real credit is due. Each fact is reproducible; the brief has the exact source quote and re-check command.
From biochar (200+ yr) to DAC+ocean storage and geologic storage (1,000+ yr): a real methodology library, not one product.
Standard-setter AND registry, deliberately
Puro writes the rules and runs the ledger, which is exactly why independent dMRV firms like Carbonfuture exist, to keep supplier-data handling out of the standard body's own hands.
No agent-discovery manifest
Real robots.txt (200, allow-all) but llms.txt/ai.txt/agent-card/openapi all TRUE 404, byte-identical to a nonsense-path control. A gap, not a fake.
The brief
Capability brief
Four evidenced findings, credit-first
Puro's live registry scale, its methodology-vs-dMRV division of labor, and a fresh agent-discovery probe this pass ran fresh.
Puro.earth is a registry: EWP's honest role here is as a last-mile field-capture layer feeding upstream evidence into a batch dossier, never a parallel issuer of CORCs. Isometric explicitly publishes "full provenance and data behind each certificate"; that's the bar this package credits as the standard EWP's own on-chain proof (photo + geofenced GPS + signature, settled same-transaction) should be measured against, and hasn't yet fully cleared (see the EWP-side self-critique in the Isometric brief). Puro's own registry publishes project and transaction browsing but a comparably explicit "full data per certificate" claim was not found live this pass, noted as a nuance, not a knock.
What this hub asks for, and what it doesn't
Not a partnership pitch, not a sales ask. No one at Puro.earth knows this package exists. It is a courtesy-grade technical note prepared entirely from public information.
What it explicitly is not: a claim that EWP packets are carbon-credit-eligible, a claim of any integration or affiliation, or a request for a meeting.
The honest smallest next step, if ever raised: a documentation exercise mapping EWP's work-definition schema fields to Puro's named proof-point lists, zero code change, zero contact required first.
Puro didn't ship something broken, it shipped a real methodology library and a real daily-updated registry. The honest opportunity isn't to replace that; it's being the cheap, plentiful, last-mile data underneath it, if the seam is ever worth building.
