A clean yes-or-no version of the Build Race for the most visible construction narrative in technology and power markets.

Resolution architecture
Census publishes the raw observation. Homecastr freezes the release artifact and exposes the deterministic rule. The exchange maps that result to its own contract.
01 / SOURCE
The first Census private-SA workbook containing June 2026 data supplies the settlement values.
02 / PROOF
Retrieval time, source URL, content hash, and archive URI preserve exactly what the resolver read.
03 / RULE
Published integer values flow through a disclosed formula, tie rule, and revision policy.
Every detail page contains the question, current benchmark, source labels, formula, tie treatment, and release-freezing procedure. The same definitions are available as JSON for integration review.
