MISSION -- THE GONDWANA RECONSTRUCTION
Five continents once fitted together. Drag them into position. Toggle four evidence layers: coastline geometry, Mesosaurus distribution, glacial striations, and matching rock sequences. India fits in two places -- the decoy is honest geology. (MS-ESS2-3)
THE LAW
The coastlines are one witness. You have four.

PROVENANCE
Fixture: Gondwana Reconstruction
Real case: Gondwana supercontinent, ~300-180 Ma
Citation: Torsvik & Cocks, 2013, Earth-Science Reviews
No generator (D10): the fixture library is the real Earth.

SEAM HANDLES
Geo Forge: Plate boundaries from this reconstruction map to Geo Forge's seismic/volcanic hazard bands — the Himalayan collision zone, the Mid-Atlantic Ridge, and the East African Rift are all seams from this assembly
Climate Engine: Continental positions control ocean circulation patterns — Gondwana's breakup opened the Drake Passage, which established the Antarctic Circumpolar Current and initiated Antarctic glaciation
