Research findings
Comparative structure study
The largest recorded industry, Advanced equipment, contains 57 records (35.8% of this 159-record cohort). The remaining cohort contains 102 records. The comparison concerns archive composition.
The recorded industry label Next-generation information technology accounts for 12.6% here (20/159), compared with 23.4% in the parent set (687/2,930), an absolute gap of 10.9 percentage points.
133/159 companies link to pages with existing source-supported excerpts (83.6% of the cohort). The other 26 records remain usable for archive composition, but do not support new operating case studies.
