Definition and scope
Use the original question domain, assumptions and cited MKO definitions. This item has second-context mathematical and bilingual review, with the model, answer and every arithmetic step independently recomputed from the original parameters; the source question remains a candidate.
all pipeline flags,names and receipt fields are synthetic input data
After
no actual Lean run,digest verification,name resolution or kernel acceptance is claimed
Conditions: none
These are supplied synthetic receipts,not a Lean run.String fields,coherent flags or complete metadata do not establish actual elaboration,file-digest verification or kernel acceptance.The teaching candidate remains not formalized.
Deduplicate and sort in the specified English locale while preserving every opaque name's characters and case.Names are neither translated nor semantically resolved.
Test complete-name membership in the declared inventory.Similar spelling,prefixes or a package's possible availability do not replace this membership test.

Result
(env-19, [Nat, x19], [h, Nat, x19], [], Yes)
The full substitutions and premise checks give the original answer; source identity,format and status are unchanged.
