"HORIZON SHIELD checks whether a Japanese construction or renovation estimate is fair. Give it a work type and a quoted price, and it compares the amount against fair-price ranges curated from 30 years of on-site construction experience, flags overcharge risk, and explains unit prices. It also detects common high-pressure sales phrases. Backed by JCCDB, an open construction-cost dataset of 65,729 items across 63 categories."
"Checks whether a Japanese construction or renovation estimate is fair. Give it a work type and a quoted price in JPY and it returns the typical range, a verdict (ok, watch, alert, or ambiguous when candidates disagree), known overcharge and high-pressure sales tactics in the wording, and contractors in Japan that passed the same independent check. Every fair-price verdict carries a SHA-256 hash anyone can recompute, and price ranges come with the source row ids and formula. Built on JCCDB, an open construction-cost dataset (v5.1, 526,128 records, CC BY 4.0). Two tools append a public ledger record; the rest read."
