Legacy material syntax

The material uses rejected draft syntax. Parsing returns diagnostics rather than accepting the draft, and a recoverable draft receives a material.text.apply source replacement. Texture-slot migration chooses a semantic fallback because it cannot infer the original asset.

#Common causes

• Material headers or declarations embed draft asset/node IDs, or values use array literals or numeric texture slots.
• Static parameters use explicit variants arrays, custom calls use custom. prefixes, or cost declarations use positional arrays.

#Fixes

• Review and apply the attached material.text.apply replacement; replace any suggested texture fallback with the intended symbolic asset.

• Use name-based declarations, scalar or vec/mat/linear/srgb constructors, and static param name : bool = true; for switches.

• Call custom functions by name and write costs as cost(alu: N, samples: N, branches: N).
