All of it: the words, the place, the proof

Test creatinine and cystatin C at an accredited lab in Winston-Salem and log the combined eGFR. Forsyth County, NC was one of the 4 original US field-center communities of the Cardiovascular Health Study, the actual cohort behind this standard's muscle-mass-independent mortality evidence: 4,663 elderly adults followed a median 9.3 years, each 1-SD (0.18 mg/L) rise in cystatin C carrying a hazard ratio of 1.33 for all-cause death and 1.42 for cardiovascular death, independent of creatinine-based eGFR (Shlipak MG, et al. Ann Intern Med. 2006;145(4):237-246). Chronic kidney decline is usually silent until late, and creatinine-only eGFR misreads people with high or low muscle mass. Confirmed directly via a WebFetch of the Cardiovascular Health Study's own site (chs-nhlbi.org), which lists all four field centers by name: Forsyth County, North Carolina; Sacramento County, California; Washington County, Maryland; and Pittsburgh, Pennsylvania. Offered in a second of the four real communities that built this evidence, distinct from the existing Sacramento tile.

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: Creatinine + cystatin C with the combined eGFR (mL/min/1.73m²) and reference range, compared for flagging only
This is exactly what gets it approved. Nothing settles without it.

How this work is done

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

Bring

accredited-lab requisition (creatinine + cystatin C, eGFR reported)
chain-of-custody label
note on hydration, recent heavy exercise, and creatine intake

Steps

1. Arrange creatinine and cystatin C through an accredited lab so a combined eGFR can be reported (cystatin C removes the muscle-mass bias of creatinine-only eGFR).
2. Record hydration status, recent heavy exercise, and creatine supplementation (all can transiently shift creatinine).
3. Capture creatinine, cystatin C, and the reported eGFR (mL/min/1.73m²) with reference ranges.
4. Place eGFR against the ≥60 threshold for flagging only.
5. Attach the report; log the values, context, and eGFR band; sign it.

What counts as done

Creatinine and cystatin C from an accredited lab with the reported eGFR
Note hydration/recent heavy exercise or high creatine intake (can shift creatinine)
eGFR placed against the ≥60 threshold for flagging only

Proof is measured against these, not judged by taste.

What is promised, and what is not

Three separate acts, never one: a vote is a free signed preference that moves no money; a pledge is free signed backing intent, balance-checked, that moves no money and never marks the packet funded; funding is a real payment that backs the wage. Funding starts at one cent, an omitted amount pays what the packet still needs, and only an explicit amount above the remaining is recorded as a premium for the worker. Money settles only on accepted proof. An agent can fund it in one x402 call: POST /nurture/fund {"workId":"WORK_1790550021711_kes9qen","funderWallet":"0xYOU"}.

Claiming is free. You sign to prove the wallet is yours: no card, no deposit, no fee. Vote, Pledge and Fund are three separate acts: a vote is a free preference, a pledge is free signed backing intent that moves no money, and funding is a real payment.

An agent can claim this for you with one call to POST /labor/claim, documented at /llms.txt.

Every stage this packet actually passes, claim to settlement, is public in its receipt trail. A stage that has not happened is not claimed.

Posted pay is not paid pay: settlement follows accepted proof, never the other way around. Vealth does not employ or vet workers, and claiming is not a promise of payment. See how proof and receipts work.

Other acts: vote, pledge, fund
