Bibliographic record
Abstract
This report describes the update to Pipeline Research Council International (PRCI) threat categories, originally described in L51885 and L52317 for primarily onshore gas pipelines. The update was completed by reviewing threat categories published in Australia, Canada, Europe, and the USA. PRCI members were involved in reviewing the updated threat categories and their feedback was incorporated. The updated threat categories are now applicable to onshore, offshore, pipelines, facilities, and liquid and gas products, enabling integrity engineers to consider a variety of damage mechanism-based threats with a proposed conceptual test that requires consideration and documentation of a threat within an integrity management plan. The report also allows pipeline and facility incidents to be attributed to threat categories with higher fidelity than previous threat category systems.
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.

Full frame machine prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
