SUEWS database pre-migration workbook: database.xlsxLater compilation

Where: Pre-migration Spartacus material row 36248175

Stores Sandstone with albedo 0.35, emissivity 0.915, conductivity 1.8, specific heat 1000 and density 2300, plus the legacy reference removed by PR

Establishes migrated configuration identity and values only.

Applied GeothermicsValidation

Where: Table 2.6, conditioned sandstone properties, p. 106

Publishes several sandstone conductivity, density and specific-heat combinations, none matching the complete stored tuple; 0.915 is a specific heat, not emissivity.

Where: Tables 2.9 and 2.10, generic sandstone properties, p. 107-108

Gives specific heat 920 J/(kg K) and generic density 2.35-2.97 g/cm3, not the stored values.

Where: Complete-monograph radiative-property sweep, p. 33 and Tables 1.7-1.8

Finds no rock albedo or emissivity table; the occurrences are planetary or the Stefan-Boltzmann symbol.

Establishes that the monograph does not support the stored generic Sandstone tuple.

Assessment findings

Namesupported
The pinned migration row identifies the retained generic Sandstone material configuration.
Targetsupported
The row is a material entry with radiative and thermophysical fields, matching target material.
Valuessupported
The migration row stores the complete five-value tuple exactly. The book close-read establishes that those values are not a coherent Eppelbaum sandstone row; support here means exact configuration preservation, not scientific validation.
Sourcesupported
Source unreferenced is correct. The complete cited monograph was checked and does not publish any of the five parameters as this generic Sandstone tuple; PR #479 removed the unsupported attribution.
issue #390 · issue #391 · issue #392 · issue #393 · issue #394
Placenot applicable
A generic material record makes no observation-place claim.
Representativenessnot applicable
A generic material entry does not declare site, city or regional evidence reach.
Methodsupported
Assumed identifies a retained material configuration whose original component sources and assembly procedure have not been recovered.
issue #390 · issue #391 · issue #392 · issue #393 · issue #394
Identitysupported
Stable path, legacy ID 36248175, name, category, display colour and exact tuple preserve the migrated material row.

Scientific note

The evidence establishes an exact archived material configuration and rules out its former Eppelbaum attribution. It does not establish the original optical or thermophysical sources. The values therefore remain unchanged with source unreferenced and method assumed. This sidecar remains agent assessed and should enter the focused human review of assumed records.
