SUEWS database pre-migration workbook: database.xlsxLater compilation

Where: Pre-migration Spartacus Surface row 37243437

Stores the exact roof and wall assembly, Gothenburg origin, wInsulation 6 and Ref 90242357. This establishes release and migration lineage, not publication support from Bjork.

Where: Official QGIS UMEP 4.4.3 release archive

The archive contains workbook SHA-256 50dfc15322115651f672fed86df1fdcc7dc8b13a58b7ced9b2e270b388aee6d3 with legacy row 37243437 set to wInsulation 6.

SUEWS database pre-migration workbook: database.xlsxValidation

Where: UMEP commit ee02726 and official 4.5 release

First public revision with row 37243437 wInsulation 2. The change is retained in UMEP 4.5 and later, but no commit message, issue, cell annotation or changelog explains its evidence basis.

Where: Official QGIS UMEP 4.5 release archive

Contains workbook SHA-256 53ba334067cbe51f98e42b3f6ee9544f2567184de9540a3982e05dbe3a690c81 with the same construction row set to wInsulation 2.

Assessment findings

Namesupported
The archival display name states the exact UMEP release identity selected by the maintainer and does not present the configuration as a construction verified from Bjork.
Targetsupported
The historical row defines roof and wall material assemblies and insulation indices, matching the construction target.
Valuessupported
The values are retained exactly as the migrated UMEP 4.4.3 configuration. In particular, wall_insulation_layer 6 means no designated wall-insulation layer; the later value 2 is documented as a release divergence rather than silently substituted.
Sourcesupported
Unreferenced is correct for the archived configuration because the Bjork source could not be inspected and no located publication establishes the complete assembly or insulation index. source_legacy_ref 90242357 preserves the migrated Bjork registry link without exporting it as proof.
issue #375
Placesupported
The historical row explicitly gives Origin Gothenburg, Sweden.
Representativenesssupported
City records the Gothenburg application identity of the archived row, not a claim that its physical assembly has been independently verified across the city.
Methodsupported
Assumed denotes the explicit curation decision to preserve the 4.4.3 release behavior while the later 4.5 change lacks a published rationale.
Identitysupported
Legacy ID 37243437 is continuous across both official artifacts. The stable record intentionally represents the migrated 4.4.3 snapshot, while the sidecar records that current UMEP uses value 2.

Scientific note

This is an identity and release-policy resolution, not a claim that value 6 is scientifically preferable to value 2. UMEP 4.4.3 and the database migration use 6, which makes the wall one horizontally aggregated layer. UMEP 4.5 and later use 2, which separates the 1 mm felt-sheathing layer during aggregation. Total material thickness and steady thermal resistance are unchanged, but transient storage behavior may differ. The maintainer chose to preserve historical 4.4.3 behavior; the record is therefore explicitly unreferenced and assumed, with the later release divergence retained as evidence rather than overwritten.
