Archaeological Evaluation Report 675 London Road, Ditton, Aylesford, Kent
Bibliographic record
Abstract
The evaluation involved the mechanical excavation under archaeological supervision of three 20m x 1.8m trenches Where necessary, surfaces were hand cleaned for examination and deposits observed were recorded on standard pro-forma and a digital photography record was maintained throughout the project. All work was carried out according to the Kent County Council Manual of Specifications Part B (Trial Trenching), the agreed Written Scheme of Investigation and in accordance with the Chartered Institute for Archaeologists (CIfA) standards. The evaluation revealed that all three trenches were heavily truncated down to the natural sand with no evidence of any surviving archaeological deposits. The northern portion of trench 1 was additionally truncated by the presence of a hitherto unidentified underground storage tank and associated pipework. It was later identified as the remnant of a former petrol station and it is likely that further underground tanks are present in the northwestern quarter of the site. The surrounding topography reveals that the site has been terraced, possibly as a result of the quarrying activity identified on the 1945 mapping. The eastern boundary of the site reveals the original slope of the land adjacent to trench 2. This indicates truncation of 4.10m at the southern end of trench 2. The depth of truncation reduces to the north as the adjacent land slopes down but is still severe enough that no early deposits survive above the natural sand. Both trenches 1 and 3 were heavily contaminated by hydrocarbons, probably leached from adjacent fuel tanks. Trench 2 was uncontaminated, and significantly not close to any of the identified fuel tanks. No archaeological deposits were present within the trenches and it is likely that the entire site has been truncated down to natural.

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.
