The finite type is Fin(6)={0,…,5}. Complete characteristic table bits=[0, 0, 0, 1, 1, 1] uses 0/1 membership from index 0; ordered queries=[100, 1, 5]. Give (type-eligibility mask, membership truth values or ill-typed).
G001 — The finite type is Fin(6)={0,…,5}. Complete characteristic table bits=[0, 0, 0, 1, 1, 1] uses 0/1 membership from index 0; ordered queries=[100, 1, 5]. Give (type-eligibility mask, membership truth values or ill-typed).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.
Before
declared finite type or bounded integer universe
After
membership truth is distinct from eligibility to ask the question
Conditions: none
Being outside the type is not the same as false membership.Check only the declared finite type or integer set,not all set theory or unrestricted comprehension.
Rule: finite_membership_scope · Uses: G001
Before
legal index=0∈Fin(6);bit=0
After
membership=False
Conditions: none
In the complete characteristic table,1 means true membership and0 false;both are valid typed judgments.

Before
legal index=1∈Fin(6);bit=0
After
membership=False
Conditions: none
In the complete characteristic table,1 means true membership and0 false;both are valid typed judgments.

Rule: complete_characteristic_bit · Uses: G001, S006
Before
query=100;legal in Fin(6)=No
After
type mismatch
Conditions: none
Check typing before reading a bit;do not replace ill-typed with False.For Fin(0),every integer query is outside the type.
Rule: typed_membership_query_guard · Uses: G001, S007
Before
query=1;legal in Fin(6)=Yes
After
False
Conditions: none
Check typing before reading a bit;do not replace ill-typed with False.For Fin(0),every integer query is outside the type.
Rule: typed_membership_query_guard · Uses: G001, S008
Before
query=5;legal in Fin(6)=Yes
After
True
Conditions: none
Check typing before reading a bit;do not replace ill-typed with False.For Fin(0),every integer query is outside the type.
