Reconstructions

Seven historically grounded reconstructions appear: City Hall; two Arsenal views; two Old Pervomayskaya views; Aldwych–Strand; and a Berlin ghost station. Each is visibly labeled AI RECONSTRUCTION · BASED ON HISTORIC REFERENCES throughout its appearance. Fictional Platform Zero imagery is separately labeled AI-CONSTRUCTED IMAGE · FICTIONAL STATION. None is presented as an archival photograph.

The incorrect Buenos Aires/Istanbul image from the earlier working set is excluded. The 1985 Mayakovskaya photograph is also excluded rather than presented as a wartime image. One duplicated London shelter source is used only once.
