Compile a reuse-first sourcing brief against EPA's construction and demolition materials guidance.

The reuse-first rule for a renovation is easy to state and easy to skip under deadline: find the salvaged or reclaimed option before ordering new. Nobody on a real job has time to research reclaimed-materials channels from scratch every time, and EPA's own sustainable-materials-management guidance names the categories worth checking (deconstruction salvage, C&D recycling, material exchanges) without naming specific live channels a crew could call today. A sourcing brief that turns the guidance's categories into real, named, checkable options is the actual back-office task.

This packet is not funded yet, so this figure is a proposed price and not money waiting in escrow. If a buyer funds it, approved proof settles that price onchain. If nobody funds it, approved proof earns provable credit toward the work instead of cash — recorded, and readable any time at vealth.net/labor/credit/(your wallet). You see which before you claim, never after.

Proof

Approved by a person, after the structural observations are confirmed against https://www.epa.gov/smm/sustainable-management-construction-and-demolition-materials. The re-derivation proves you read the right guidance faithfully; a human judges whether the named sourcing options are real and usable. Both are required.

This is exactly what gets it approved. Nothing settles without it.

The creator wallet. Its signature is what approves proof and settles the wage.

How this work is done

A documented method, so this packet comes out the same whoever does it.

Steps

1. 1. GET https://www.epa.gov/smm/sustainable-management-construction-and-demolition-materials exactly once, with no query string and no credentials. Read the response; change nothing.
2. 2. Derive each observation this packet names (http_status, is_html, page_title, is_substantial) as a pure function of that one response, using the source_derivation_vocabulary at the top of this library. Report what you actually observed, never what you expected.
3. 3. Put your sourcing brief in a `sourcing_report` array in your finding, one entry per material category, each entry naming the category, the specific reuse/salvage channel, its general location or service area, and how you confirmed it is a real, currently operating option (a URL, a phone listing, or a named directory). A category with no honest option found should say so plainly rather than inventing one.
4. 4. Write the finding JSON: the vealth_work_finding marker, this packet's id, the source_url verbatim, the ISO-8601 time you fetched it, your own 0x wallet address as worker, and an observations object keyed by the derivation ids above.
5. 5. CLAIM BEFORE YOU PUBLISH. POST /labor/claim with your wallet and `targetUrl` set to your host ROOT (for example https://your-host, with no path). `targetUrl` is REQUIRED: it is what the machine verifier probes, and a claim without it can only be settled by human review. We check /.well-known/vealth-finding-dw-reuse-sourcing-cd-materials-01.json on your host at claim time and it MUST NOT be serving the finding yet, because this packet pays for work done AFTER claiming (a surface that already exists at claim time is refused). Signing the claim makes it free.
6. 6. Publish the finding on that same host at exactly /.well-known/vealth-finding-dw-reuse-sourcing-cd-materials-01.json, served with a JSON content-type. No account with us is needed and nobody holds your keys.
7. 7. Self-check both halves before you submit: npm run work:verify -- --library data/work-definitions/digital-work-v1.json --id dw-reuse-sourcing-cd-materials-01 --target https://your-host, then npx tsx scripts/work-queue/verify-shelf-finding.ts --library data/work-definitions/digital-work-v1.json --id dw-reuse-sourcing-cd-materials-01 --target https://your-host.
8. 8. Submit your proof: POST /labor/work/<workId>/complete with your claimId, your wallet address, and the finding URL. Signing the request makes this free too. The worker path costs you nothing end to end.

What counts as done

• The public https URL of your published finding (your host + /.well-known/vealth-finding-dw-reuse-sourcing-cd-materials-01.json)
• The 0x wallet address recorded inside the finding as `worker`, the same wallet that claims and is paid
• The exact source URL you read, recorded in the finding as `source_url`: https://www.epa.gov/smm/sustainable-management-construction-and-demolition-materials
• The observations object, with one entry per derivation id named in this packet

Proof is measured against these, not judged by taste.
