Abstract
As a result of a condition on the planning permission for the construction of a new housing development with associated below ground car parking at Brooker's Yard, Hitchin, Hertfordshire, the Heritage Network was commissioned by the developer to undertake a programme of archaeological investigation. Two stages of archaeological fieldwork were undertaken, comprising an open area excavation followed by a programme of observation and recording of groundworks. The open area excavation was undertaken in two phases: Phase 1 comprised a small area to the rear of the Corn Exchange on the Market Place frontage; Phase 2 comprised the footprint of the proposed underground car park that covered a large portion of the centre of the site. The monitoring programme focussed on the removal of petrol tanks and the excavation of footings trenches on the Paynes Park frontage. The works revealed a number of significant medieval and post-medieval archaeological remains. A large defensive boundary ditch was observed crossing the site on a north - south alignment. The ditch is thought to form part of the defences of the late Anglo-Saxon - early medieval settlement at Hitchin. Medieval burghage plot boundaries with associated rubbish pits were observed running on an east - west alignment across the site. Significant evidence for medieval industrial activity was observed to the rear of the Tilehouse Street frontage with remains in particular associated with the pottery and tile manufacturing industries. A continuation of the industrial activity on the site was observed in the form of the remains of a number of Victorian and later chimney stacks with associated flues and coal bunkers possibly associated with the Iron Foundry known to have occupied the site in the 19th century.

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.
