Shore line of Lake Ontario at Port Dalhousie
Bibliographic record
Abstract
Historic map showing the Lake Ontario shore line at Port Dalhousie. North is oriented left towards the lake. Text below the title indicates the time frame that the shore line map is representative of: “as it was in 1844” and “as it is now (1883)”. Although this is a black and white version, the original had the 1844 shoreline indicated in blue and the 1883 line indicated in red. Lock 1 of the Second Welland Canal and the line of the First Welland Canal are shown. The Village of Port Dalhousie is labelled and Lock Street is shown beginning at the lake and running through Port Dalhousie to a tow path. Also shown on this map are various locations relevant to Welland Canal operations, including: Collector’s House, Sail Loft, Muir’s Dry Dock, Shore House, Collector’s Office, Weir, Wain and Andrews Dry Dock. A new harbor is located to the east of Port Dalhousie and a road to St. Catharines to the south. A note at the bottom of the map reads as follows: “Shore Line colored RED taken June 29th 1883. Level of Lake 14 feet on Mitre Sill of Old (2nd) Canal.” Signed: "Thorold, 2nd July 1883. Thomas Monro". "RG 43 vol. 804 Folder 85 #14848 (?)" written in top right margin and bottom right margin.

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.
