Owls Farm, Owles Lane, Buntingford, Hertfordshire. Stage 2: Geophysical Survey
Bibliographic record
Abstract
In order to inform a possible planning application for a development at Owles Farm, Owles Lane, Buntingford, Hertfordshire, the Heritage Network was commissioned by the owners to consider the archaeological potential of the site in line with the requirements set out in para.128 of the National Planning Policy Framework. The site lies to the east of Buntingford, on a ridge of higher ground between the valleys Haley Hill Ditch and the valley of the River Quin. The first stage of work involved the preparation of a Desk-based Archaeological Impact Assessment covering the moated site which forms the core of the study area. It was considered that the backfilled moat was likely to preserve important organic deposits and palaeo-ecological evidence, and the island is likely to preserve structures and artefacts that demonstrate the history of the site and the use to which it was put. The desk-based assessment suggested that the archaeological investigation of the site would benefit from a preliminary survey, using non-invasive geophysical techniques, to try and establish the full extent of the moat and the area enclosed by it, and the layout of activity on the island. On this basis, a detailed gradiometer survey of the study area was commissioned by the owners, and carried out at the end of October 2012. The survey identified a number of magnetic anomalies that probably relate to the former moated site and its associated archaeological activity. The gradiometer survey has confirmed the presence and location of the moat, including the eastern arm that is not shown on the available mapping. It has also revealed a number of other linear features that may represent occupation on the site. The large, highly magnetic masses may represent building debris from the demolition of the structures that existed within the moat, or they may represent a previously unmapped building.

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.
