ProjectE commit 68fbb2dea0cf8a6394fa6c7c084063046d94cee5 supplies its
default item-tag values and metals.json relations required by PEI's host environment. These are
adapted only as missing third-party material references, never as replacements
for Valemetry's vanilla anchors or administrator prices.

The original adapters' recipe API knowledge and conversion records were
re-expressed for Valemetry's own resource graph, exact solver, optional API
reader, price policy and diagnostics. Valemetry does not bundle or require
either mod, and does not claim third-party mappings or data as original.
