An EWP proof packet, shown as one line item inside a Carbonfuture-style dossier, never a substitute for the lab.
Both acts below are illustrative concepts, built in Carbonfuture's own documented brand: no real integration, API call, or data exchange exists between EWP and Carbonfuture. The point is to show, honestly, what a small, cheap proof layer looks like sitting one rung below a much bigger one, not to claim it already works.
CONCEPT DEMO: not a real Carbonfuture integration. No data shown here has been submitted to, verified by, or endorsed by Carbonfuture, Puro.earth, or Isometric.
Act One: a field-capture packet as an evidence-bundle line item
Act 1 · Concept
Carbonfuture's own due-diligence framework asks for documented evidence across nine categories. This concept shows one small addition: an EWP proof packet (photo + geofenced GPS + one-time actor signature) attached as a single field-observation row alongside the lab certificates and weighbridge tickets a real batch dossier already requires, labeled explicitly as a field-capture input, sitting far below the accredited-lab layer, never replacing it.
EWP work packet ewp-work-14071: "confirm feedstock stockpile relocated to covered storage, Site B," photo (content-hash + EXIF GPS cross-checked) + geofenced actor signature, settled on-chain (Base) Field-capture input
Chain of custody
Feedstock source → production log → this batch, ≥5yr retention (per Puro record-keeping requirement)
VVB sign-off
Pending independent auditor review, required before any credit issues
What this is, plainly: one field-observation row, not a carbon measurement. EWP proves the stockpile got moved, by whom, where, cheaply and same-day. It does not, and cannot, substitute for the accredited Corg/H-ratio assay or the calibrated scale ticket above it. That's the honest boundary this whole brief is built around.
Act Two: packet-sized labor around a missing-middle plant
Act 2 · Concept
Carbonfuture's own thesis names a real gap: plants "beyond early equity, but not yet bankable," with 70% of its suppliers needing capital within six months. EWP's packets can't fill a $1–5M financing round, but a plant in that exact position still has small, real, physical work that needs doing while it waits: feedstock collection, invasive-species clearing, site prep, ongoing maintenance. This concept funds three of those as individually bounded EWP work packets.
Plant awaiting Series A / mezzanine financing→Adjacent EWP labor keeps site active→Site-ready when capital arrives
Feedstock collection: invasive mesquite clearing, 0.5 ha plot
Concept packet modeled on Biomass Projects' Mardie char thesis (300,000+ invasive-mesquite hectares named in the public record). Funded, claimed, proven (photo+GPS+signature), settled same session. $4.20 packet · USDC on Base
Site prep: covered storage build-out, feedstock stockpile
Bounded maintenance task at a first/second-commercial-scale plant site, funded independent of the plant's own project-finance timeline. $2.80 packet · USDC on Base
Repeating, small-ticket ecological/site labor that keeps a pre-bankable plant field-ready without waiting on the plant's own capital raise. $3.15 packet · USDC on Base
What this is, plainly: a concept sized to the actual gap Carbonfuture's own thesis describes: adjacent, small-ticket, physical labor around a plant that's real but not yet financed. It does not, and is not claimed to, close the $1–5M equity/mezzanine gap itself.
Both acts stay inside EWP's real unit economics: sub-dollar, single-task, same-session settlement. Neither one claims to be carbon-credit-eligible, VVB-reviewed, or integrated with Carbonfuture today. That honesty is the entire point of showing this as a concept, not a pitch.
