Why this score?

Historical source clarity15 / 20
The source clearly names different ends and a downtown circulation, with short compressed connector descriptions.
Mapped extent completeness15 / 20
The main open journey is represented; precise initial access still needs definition. No return to East Hill is invented or required for this score.
Geometry consistency20 / 20
The available open sequence forms one connected part without recorded sequence breaks or local direction conflicts. A closed-loop witness is not required for its stated open scope.
Recent direct field evidence0 / 20
No completed, reviewed ride record for this route is attached to the research baseline. Historical descriptions, map edits and unreviewed reports do not establish a currently observed full journey.
Independent field corroboration0 / 20
No accepted independent check corroborates a dated route-specific field record in this baseline. Reuse of the historical official description is not independent observation.

What still needs checking

Frederick-to-Market omits Princess/OSM Prince; D01 supplies a physical candidate.
Initial East Hill-to-Market access is compressed.
No return from the stated final Baillou Hill/Robinson corner to the depot is described.
