3toEquala

3toEquala is a software framework that seeks to bridge three-valued logic and classical boolean representations. It provides algorithms and data structures for translating expressions that use a ternary truth value—true, false, and unknown—into equivalent two-valued expressions while preserving key semantic relationships such as logical equivalence and implication. The project emphasizes predictable handling of indeterminate values through configurable policies, enabling integration with existing boolean engines and decision-rule systems.

Its architecture centers on a modular translator, a normalization layer, a constraint engine, and language adapters. The translator expands ternary expressions into boolean form, while the normalization layer applies selected policies for unknowns, such as treating unknowns as false, true, or propagating uncertainty. The constraint engine enforces equality relations across transformed expressions, and adapters provide interfaces for Python, JavaScript, SQL, and other data formats. The framework is designed to be extensible, allowing developers to plug in custom policies and rule sets.

3toEquala is released under a permissive open-source license and is maintained by a community of contributors. It is intended for use in data processing pipelines, formal verification, knowledge representation, and decision-support applications where ternary data must interact with binary systems. The project supplies a command-line tool, an API, and example notebooks demonstrating typical workflows.

Reception in its user community focuses on policy-driven handling of unknown values and on interoperability with standard boolean engines. Related topics include ternary logic, three-valued logic, and logical translation.
