Inline comments:
In `@lib/duckdb/logical_type.rb`:
- Around line 58-61: The resolve method in DuckDB::LogicalType is currently
using const_get with inherited lookup, which can return unrelated constants from
ancestors; change resolve(symbol) to perform a non-inherited lookup (e.g., use
const_defined?(symbol.upcase, false) and then const_get(symbol.upcase, false) or
const_get with inherit: false) so that only constants defined directly on
DuckDB::LogicalType are returned and otherwise raise the existing ArgumentError.

🧩 Analysis chain
🌐 Web query:
Ruby Module#const_get inherit parameter behavior documentation
💡 Result:
Module#const_get(name, inherit = true) controls whether Ruby searches ancestors when resolving the constant name:
- Default (
inherit = true): Ruby looks for the constant in the receiver, and if not found, also searches the receiver’s ancestors. Additionally, if the receiver is aModule, Ruby also searchesObject(and its ancestors). (docs.ruby-lang.org) inherit = false: Ruby only checks the receiver itself (no ancestor /Objectlookup). (docs.ruby-lang.org)- Qualified names (
"A::B::C"): Ruby resolves the path step-by-step, and theinheritflag is applied at each step (soinherit: falsecan prevent a later segment from being found via inheritance). (docs.ruby-lang.org)

Disable inherited constant lookup in resolve to prevent returning unrelated constants.
const_get with the default inherit=true searches ancestors and Object, so symbols like :env can resolve to Object::ENV instead of raising ArgumentError. This violates the contract that only DuckDB::LogicalType constants should be returned.
💡 Suggested fix
class << self
def resolve(symbol)
- DuckDB::LogicalType.const_get(symbol.upcase)
+ DuckDB::LogicalType.const_get(symbol.to_s.upcase, false)
rescue NameError
raise ArgumentError, "Unknown logical type symbol: #{symbol}"
end
