//
// DynamicTailKey's inventory (declared above, one line per reader) is an exact,
// hand-maintained enumeration of what the six Apply* in the tail read. The P2 chunk table
// (MG_Pipe/MGPipeRenderStateSpans.h) is an independent, offsetof-derived statement of
// which bytes of RenderStateParameters are dynamic state. The two were written for
// different reasons, so making them check each other is free evidence: if a later chunk
// edit demotes or promotes one of these members, the mismatch is a BUILD BREAK here rather
// than a tail that silently stops being re-run when its input moves.
//
// The brief (P2 D12.3) expects every input to be dynamic; the tree says otherwise for
// exactly one, and the tree is right - see the ScissorTestEnabledMask note below.
//
// These assertions ARE D19's DynamicChunksCoverMagmasDynamicTailKey, in the only file this
// package owns. D19 names it as a case in MG_Test/Pipe/RenderStateSpansTest.cpp, which
// belongs to package A (C.5). INTEGRATOR: make sure the outcome is not "neither" - if
// package A did not land that case, this static_assert block is the whole gate, and if it
// did, the two are redundant on purpose and both should stay.
