Historic Building Recording A14 Cambridge To Huntingdon Improvement Scheme: Milestones On The A1 And A14, Alconbury To Cambridge Cambridgeshire
Bibliographic record
Abstract
The recording was carried out in line with Historic England Level 2 historic building recording guidelines. The objective of Historic England (HE) Level 2 building recording is to provide a descriptive record of an extant structure in accordance with the Historic England document Understanding Historic Buildings: A guide to good recording practice (HE 2016). It provides a systematic account of a building or structure's origins, development and use. Six milestones/markers were recorded during the survey, distributed over a distance of approximately 24.5 km: two (milestones 213 and 552) along the route of the A1 dual carriageway between Alconbury and Buckden, northwest of Brampton, Cambridgeshire. The post-medieval period saw a marked increase in trade, particularly towards the capital and was accompanied by an improvement and widening of main trading routes. Mile markers adhering to a standardised unit of measurement allowed for accurate pricing and scheduling of journeys. The earliest such markers were likely carved from timber posts but were rapidly superseded by stone carved pillars of local stone, into which the lettering was carved and picked out with paint. Such markers were susceptible to weathering and erosion and the painted letters required renewal. The 19th century saw the replacement of many such markers with cast iron ones which were mould produced.

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.
