SUEWS database pre-migration workbook: database.xlsxLater compilation

Where: Pre-migration Spartacus Material row 36248177

Stores the exact 0.35/0.96/2.68/1900/2650 tuple, Granite label and Ref 90240059. This proves release and migration lineage, not that Eppelbaum publishes the complete tuple.

Applied GeothermicsValidation

Applies to: parameters.thermal_conductivity

Where: Table 2.5, Granite row, p. 104

Reports N = 383 and average heat conductivity 2.68 W/(m K), compiled from the earlier datasets identified in the table footnote.

Assessment findings

Namesupported
Granite is both the historical catalogue label and the material row named in Eppelbaum Table 2.5; no narrower lithology is inferred.
Targetsupported
The historical row stores optical and thermal material properties, and Table 2.5 confirms that thermal conductivity is a granite material property.
Valuessupported
The exact five-field tuple is supported only as a retained historical configuration row. Eppelbaum Table 2.5 supports thermal_conductivity 2.68, but the book does not publish the tuple; albedo 0.35, emissivity 0.96 and an exact generic density 2650 are absent, while specific_heat 1900 is contradicted by granite values 950, 790 and 720.
issue #386 · issue #387 · issue #388 · issue #389
Sourcesupported
Unreferenced is correct because no located publication states or derives the complete tuple. source_legacy_ref 90240059 preserves the migrated Eppelbaum link, while field-scoped validation evidence retains the exact conductivity locator without exporting it across the other fields.
issue #386 · issue #387 · issue #388 · issue #389
Placenot applicable
The generic material row makes no observation-place claim.
Representativenessnot applicable
The record makes no site, city, or regional evidence-reach claim.
Methodsupported
Assumed distinguishes retention of the complete historical tuple from a verbatim literature material; the partial conductivity publication is documented separately.
Identitysupported
Legacy ID 36248177 remains the stable generic granite configuration. The record is neither split nor renamed, and its values remain unchanged.

Scientific note

Deattribution is a whole-record curation decision required by the one-source export format, not a claim that every field lacks evidence. Eppelbaum remains exact field-scoped validation evidence for conductivity 2.68. Albedo 0.35 is absent from the complete monograph: every albedo or ordinary reflectivity passage concerns planetary material, not granite. Emissivity 0.96 is absent too; the book uses emissivity only as a generic Stefan-Boltzmann symbol and contains no rock emissivity table. The specific heat 1900 is also absent and conflicts with three stated granite alternatives. Density 2650 is not stated either; the book offers a different melting-context value and a broad range that merely contains 2650. No replacement is substituted because the intended sources or transformations are unknown. All five values and the stable identity are retained as an explicit unreferenced assumed configuration, with all four unsupported fields now carrying explicit dispositions.
