The win is the verified bond to a public crystal STD. Generated material nicknames do not WIN. No minted mp- ids. No 46622-row catalog.

Using something that is not accurate (because it shears) may not be useless — it may be dangerous.

Goal

Name a crystal the way COD / Materials Project / IUCr already name it: COD number, and/or mp-#####, and/or space-group 1–230 plus a Pearson token. If a row has no STD, the game REFUSES (REFUSED_NO_STD). SOP-as-contract is this token. The recipe stays on disk.

Integer / token keys

Key	Kind	Rule
cod	Int64	positive COD file number in the authored fixture
mp_id	exact token	^mp-[0-9]+$ and present in the fixture — never minted
space_group	Int64	1…230; must travel with pearson when it is the only STD
pearson	exact token	e.g. cF8
num_atoms	Int64	optional; > 0
source + role	required	empty source → REFUSED_UNATTRIBUTED

Float density / GPa / mS/cm → HTTP 400 REFUSED_FLOAT.
