Source registry / verified 14 Aug 2026

Local evidence has to earn its way onto the page.

A working data feed is not enough. Every city and project category must pass sample, coverage, classification, duplicate, and disclosure gates before supporting a local price claim.

National methods and live program paths

Primary sources near the decisions they support.

Method sources change slowly. Incentive and tax sources can change quickly, so the site records a verification date and sends the final eligibility decision back to the program owner.

Publication gate

Five checks, every time.

  1. 01

    SampleAt least 100 included observations

  2. 02

    CoverageAt least 70% usable positive valuation coverage

  3. 03

    PrecisionAt least 90% on a human-reviewed stratified sample

  4. 04

    DuplicatesLess than 5% unresolved duplicate-project rate

  5. 05

    DisclosureSource, dates, sample, exclusions, method, and limits visible

Current publication decision

No local equipment price band is approved yet.

National calculator work continues independently. Local evidence will be added only after the full gate passes, never because a page needs a number.
