Research findings
Comparative structure study
The largest recorded industry, Advanced equipment, contains 60 records (34.9% of this 172-record cohort). The remaining cohort contains 112 records. The comparison concerns archive composition.
The recorded chain role label Advanced equipment and industrial automation / Process equipment and inspection instruments accounts for 31.4% here (54/172), compared with 25.2% in the parent set (737/2,930), an absolute gap of 6.2 percentage points.
141/172 companies link to pages with existing source-supported excerpts (82.0% of the cohort). The other 31 records remain usable for archive composition, but do not support new operating case studies.
