Build the verified backbone record for Thalassia testudinum (turtlegrass).

Planting lists are written from common names, and common names lie. "turtlegrass" is used for more than one plant, and a planting packet that names the wrong taxon puts the wrong species in the ground, the exact failure mode that turns tropical seagrass meadow restoration into damage. The GBIF backbone settles it, including whether the name we are using is the accepted one or a synonym, but nobody has recorded that answer for this taxon against a wallet.

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 when every recorded field equals an independent re-derivation from https://api.gbif.org/v1/species/5329591. If the status is SYNONYM, that is the finding. Report it as published; do not "correct" it.

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://api.gbif.org/v1/species/5329591 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_json, valid_json, scientific_name, canonical_name, taxonomic_status, rank, kingdom, family) 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. 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.
4. 4. 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-species-thalassiatestudinum-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.
5. 5. Publish the finding on that same host at exactly /.well-known/vealth-finding-dw-species-thalassiatestudinum-01.json, served with a JSON content-type. No account with us is needed and nobody holds your keys.
6. 6. Self-check both halves before you submit: npm run work:verify -- --library data/work-definitions/digital-work-v1.json --id <packet-id> --target https://your-host, then npx tsx scripts/work-queue/verify-shelf-finding.ts --library data/work-definitions/digital-work-v1.json --id <packet-id> --target https://your-host.
7. 7. 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-species-thalassiatestudinum-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://api.gbif.org/v1/species/5329591
• The observations object, with one entry per derivation id named in this packet

Proof is measured against these, not judged by taste.
