How this bucket was built

Hubstake parses each printed description into structured attributes — material, class, size, work type — and mints the identifier HS-DRN-ENDWALL-EA from them. Only descriptions the parser accounted for in full are pooled; anything it could not read in full keeps its own page and stays out of this median, because the part it could not read is usually the part that moves the price. Award, bid and final-payment prices are never blended — this bucket is award prices.
