PlaceRuinedPortalPiece runs the template through the decoded processor stack — positional Legacy streams per cell drive the gold-to-air, lava-to-magma, netherrack-to-magma and block-age mossiness rolls, the features-cannot-replace guard skips protected cells, and template lava stays when it lands in existing lava. Drip columns below the portal draw from a documented approximation of the shared decoration stream; spreadNetherrack is not needed for the underground setups. The placement chain is now proven end to end: chunk (1,0) reproduces vanilla's saved start (portal_6, CLOCKWISE_90, NONE, air pocket at (16,12,0)) and the fixture parity ticks up to 98.033% with biomes and heightmaps still exact. generatorVersion bumps to 23.
