西安城墙环城公园的公共卫生间龙头出水量远高于需要，北方每一升自来水都来之不易，而换起泡器是最便宜的一步。 / The public washroom taps at the Xi'an City Wall circumvallation park run far harder than they need to, every litre of mains water in the north is dearly bought, and an aerator swap is the cheapest first step.
Fund it for $180. Proof lands onchain when it's done.
How this work is done
How this work is done
A documented method, so this packet comes out the same whoever does it.
Steps
- 逐个龙头实测更换前流量。 / Measure the flow of every tap before the swap.
- 关闭角阀，拆下旧起泡器并清理螺纹。 / Close the isolating valve, remove the old aerator and clean the thread.
- 装上节水起泡器并拧紧至不渗漏。 / Fit the low-flow aerator and tighten until it does not weep.
- 逐个实测更换后流量。 / Measure the flow of every tap after the swap.
- 汇总每台节水量并拍摄前后照片。 / Total the litres saved per fixture and photograph before and after.
What counts as done
- 更换前逐个龙头流量记录 / Measured flow of every tap before the swap
- 更换后逐个龙头流量记录 / Measured flow of every tap after the swap
- 所装节水件型号与数量 / Model and count of the low-flow fittings installed
- 前后照片与无渗漏确认 / Before and after photos with a no-weep confirmation
Proof is measured against these, not judged by taste.
The standard this serves
Water Efficiency. Water efficiency is the quiet discipline of wasting nothing indoors. The EPA's WaterSense program sets the marks: how many gallons a minute a faucet should pass, how to find the leak that runs a toilet all night, how a household's water bill tells a story. Mastery looks like an auditor who can walk a home in an hour and find every hidden gallon. The skill is built one fixture at a time, which is exactly what this packet asks: measure one flow, find one leak, record one truth about where the water goes.
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_1789886543343_wcazhk5","funderWallet":"0xYOU"}.
Open, but not claimable yet. restricted: china-region-gps. This packet requires GPS location proof from a worker in mainland China, and the cross-border data-transfer safeguards that kind of location data needs are not in place on this protocol yet. It stays readable; voting and pledging are free, and funding is separate from claiming.
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
