Abstract

fetched live from OpenAlex

Metrolink in Los Angeles has expanded to six routes and 34,000 passengers a day since its start in 1992, making it possible to ride to San Diego on non-Amtrak trains (with transfers). Denver is undertaking one of the largest light-rail construction projects in years, a 19-mile, $1.2-billion line. San Jose and San Diego are both expanding, and GO Transit in Toronto broke its previous record for ridership with 40 million passengers in 2000.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
