The parameters are in the graph, not only in the paper. Each dating is generated by an activity, and that activity records the plan it followed — so a consumer can ask what k, τ, t₀ and the era convention were, and which datemax values the source query excluded, without reading any prose. τ and lado:referenceLength are unrelated quantities that happened to carry the same value until τ was calibrated: τ governs how fast the interval tightens as stamps accumulate, t₀ is the fixed length against which qStart and qEnd are read. lado:calibrationBasis says how τ was obtained, and lado:calibratedAgainst names the findspots it was fitted to — try following those IRIs. The excluded datemax values are an inherited filter whose justification is still open; publishing them is how that stays visible.

rdflib under Pyodide — there is no endpoint, and nothing you type
leaves your machine.
