Research findings

Comparative structure study

The largest recorded industry, Next-generation information technology, contains 237 records (29.8% of this 795-record cohort). The remaining cohort contains 558 records. The comparison concerns archive composition.

The recorded chain role label Advanced equipment and industrial automation / Process equipment and inspection instruments accounts for 26.4% here (210/795), compared with 22.1% in the parent set (810/3,671), an absolute gap of 4.4 percentage points.

615/795 companies link to pages with existing source-supported excerpts (77.4% of the cohort). The other 180 records remain usable for archive composition, but do not support new operating case studies.

A rule hit prioritises review; it does not establish that the entire field is wrong. One record can trigger several rules.

Intersection with 2026 local lists

708 of this cohort’s 795 records link through existing company-ID mappings to 2026 lists from all jurisdictions (89.1%). This intersection measures list linkage, not successful recognition or company growth.
