The coordinate pair and the absorption guard needed modules made on each PC by tools/projective_recipe.py and a folder named in NX2NAVI_SPV_OVERRIDE, so no player had them. runtime/spirv_water.c makes the recipe's edits on the translation in memory, in the recipe's order: on the NVIDIA profile its three modules are byte for byte the recipe's (RTX 5090, game 1.1.1). vk_pipeline.c keeps the edited modules in a small table, made at first use, and builds a pair from them only when both of its stages were made; a module of another shape is built as it is, with a log line. NX2NAVI_WATER_PROJECTIVE=0 turns the corrections off. tests/water_projective_check.py compares the runtime's edits with the recipe's on made-up modules.
