Stores the exact tuple, name, and Ref 90240071; this proves release and migration lineage only.

Timber studding, battens and decking use conductivity 0.13, specific heat 1600 and density 500; conductivity 0.14 belongs to other wood products with different properties. No row adds generic albedo 0.22 and emissivity 0.90 to the stored thermal trio.

Assessment findings

Namesupported
The historical catalogue row supplies the generic Wood configuration label.
Targetsupported
The row stores optical and thermal material properties.
Valuessupported
The exact tuple is supported as a retained historical configuration row, not as one CIBSE wood product. Guide A distributes the stored thermal figures across different products and identities.
Sourcesupported
Unreferenced is correct because no CIBSE row states the complete tuple. source_legacy_ref 90240071 retains the migrated registry link without exporting it as the parameter publication.
issue #263
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 configuration tuple from a verbatim literature material.
Identitysupported
Legacy ID 36248146 identifies the retained catalogue row; no wood species, product, or moisture condition is inferred beyond its historical generic label.

Scientific note

The tuple is retained exactly as a historical configuration artifact. The checked CIBSE tables do not publish it as one named wood product, and nearby rows cannot be combined without choosing a species or condition. Source unreferenced, method assumed, and source_legacy_ref 90240071 make that boundary explicit without changing values or inventing identity.
