Scenario 1

NamedTuple extras including TupleSize fixed/minimum/variable, _order_ handling, aliases, and _review_ hook

Scenario 2

Typed enums (IntEnum/StrEnum variants plus AutoNumber/Ordered/Unique options)

Scenario 3

Enum class/functional creation with iteration and name/value access

Scenario 4

NamedConstant/Constant groups that forbid rebinding and support by-value lookup

Scenario 5

NamedTuple metaclass/functional API with attribute/index access and defaults

Scenario 6

Stdlib/sqlite integration helpers such as add_stdlib_integration/remove_stdlib_integration and SqliteEnum

Scenario 7

Alias behavior tuning with MultiValue/NoAlias/Unique settings and values access

Scenario 8

Descriptor utilities (constant/member/nonmember/skip, enum_property) to manage member exposure and attribute access

Scenario 9

Flag boundary policies (FlagBoundary STRICT/CONFORM/EJECT/KEEP) and pseudo-member creation for unknown bits

Scenario 10

Flag and IntFlag bitmask enums with bitwise combination and auto bit assignment
