# Structure v3 evidence and interpretation

Plan: Parco Archeologico della Villa Romana del Casale, *Introductory guide*,
digital version1.3, March2012, printedp5; room functions onpp6–8. Original
observations, native references and accepted reconstruction decisions are retained
in the repository's structure-v2 evidence and round6 revision2 plan.

Source transforms, scale hypotheses, registration residuals and uncertainty are
recorded in elevation-v1/v2. The relative datum is peristyle19, not sea level.

Bath engineering context: Lamanna2025, printedpp69–77. Modern conservation
shelters have not supplied ancient roof heights. Flickr8044545842 depicts a
physical site model and supplies qualitative terracing, not metric measurements.

Lost upper walls, columns, windows, vaults, roofs, landscape and stair profiles
are explicitly chosen uncertain reconstruction hypotheses. Independent agent
reviews establish bounded source/visual QA, not independent scholarly validation
or survey accuracy. The100mm target concerns approximation of the selected
geometry; registered observations have larger uncertainties.

Materials are neutral. Mosaics and furnishings are deferred. Existing fictional
household characters and their appearance/routines are retained.
