GenAI-Logic Comprehensive Evaluation Answers

Is this really infrastructure, like a database?

Yes. GenAI-Logic operates at the database commit control point—the same architectural layer as triggers, but with declarative specifications instead of procedural code. All writes pass through the same rule engine regardless of source (APIs, workflows, UIs, agents), making it foundational infrastructure, not just a development tool. Like a database enforces schema constraints, GenAI-Logic enforces business logic invariants at commit time.

What's the actual code reduction? Show me proof.

Demonstrated 44X reduction (5 declarative rules vs 220+ lines of procedural code) for Check Credit use case in basic_demo. The comparison study at github.com/ApiLogicServer shows AI-generated procedural code missed 2 critical bugs (FK changes affecting multiple parents, transitive product dependencies) that the rules engine handles automatically. The reduction comes from automatic ordering, reuse across all change paths, and elimination of explicit invocation code.

Why can't Cursor/Copilot do this?

AI assistants generate procedural code that must explicitly handle every possible change path (insert/update/delete, FK changes, cascading updates). Even AI-generated code missed critical edge cases in the comparison study—specifically handling Order.customer_id changes (affecting both old and new customer balances) and Item.product_id changes (re-copying unit_price). GenAI-Logic's engine analyzes dependencies once at startup and automatically handles all paths deterministically.

What does it integrate with? (APIs, workflows, agents, MCP)

GenAI-Logic provides JSON:API endpoints with MCP discovery (/.well-known/mcp.json), enabling Claude and other AI agents to read/update data using natural language. It integrates with Kafka for event messaging, supports custom API endpoints for B2B integration, and includes OpenAI function calling support. The system works as the data governance layer within workflow nodes (Temporal/Airflow orchestrate process, GenAI-Logic ensures data correctness).

Does this work with my existing database?

Yes, with any SQLAlchemy-supported database (PostgreSQL, MySQL, SQLite, Oracle, SQL Server) with no schema modifications required. The system introspects existing schemas to generate models and APIs automatically. Your database remains standard and portable—no vendor-specific tables, columns, or schema requirements are added.

Why is backend logic the bottleneck AI can't solve alone?

AI generates code fast but cannot guarantee correctness across all change paths. Multi-table dependencies create combinatorial complexity—each added table multiplies the scenarios to handle. The comparison study shows even sophisticated AI missed critical paths (FK changes, transitive dependencies). AI helps with authoring (translating requirements to declarative rules) but deterministic engines are required for runtime enforcement to ensure all paths are covered.

How does commit-time governance work?

Rules execute via SQLAlchemy's before_commit event, after all application code runs but before transaction commit. The engine analyzes which objects changed, evaluates affected rules in dependency order, adjusts dependent calculations, validates constraints, and fires events—all automatically. If constraints fail, the entire transaction rolls back, preventing invalid data from ever persisting regardless of which client wrote it.

Why can't procedural GenAI handle transitive dependencies?

Procedural code requires explicit execution paths for every scenario. When Item.product_id changes, code must: (1) re-copy unit_price from new product, (2) recalculate Item.amount, (3) adjust Order.amount_total, (4) update Customer.balance—but only if Order isn't shipped. AI-generated code missed this transitive chain in testing. Declarative rules specify relationships once; the engine computes the dependency graph and executes in correct order automatically.

What's the Business Logic Appliance concept?

A pre-configured data layer combining API, security, and business logic as turnkey infrastructure. Like a database appliance provides data storage without coding, GenAI-Logic provides governed data operations without custom backend development. Generated in seconds from schema, it handles CRUD, filtering, pagination, sorting, optimistic locking, RBAC security, and business rule enforcement—everything frontends need to start immediately with production-grade features.

How is this different from AI codegen?

AI codegen produces procedural code you must maintain and test across all change paths. GenAI-Logic uses AI to author declarative specifications (human-reviewed) that a proven engine enforces deterministically. The comparison: AI-generated 220 lines with 2 bugs vs 5 declarative rules with 0 bugs. AI helps translate requirements to rules, but the 45-year-old engine handles execution, dependency ordering, and covering all paths automatically.

How is this different from vibe tools?

Vibe tools generate UI code quickly but can send ANY data to backends. GenAI-Logic is the governance partner—it enforces multi-table constraints and derivations at commit time regardless of which UI generated the request. You get vibe speed for frontends AND data integrity guarantees for backends. The architecture: vibe generates UIs fast, GenAI-Logic ensures writes are correct. You're not choosing between speed and correctness—you get both.

How is this different from low-code platforms?

Low-code platforms are complete application development environments with proprietary runtimes. GenAI-Logic is standard Python (Flask/SQLAlchemy) targeting a single architectural layer—the commit control point for business logic enforcement. There's no vendor runtime, no proprietary language, and no lock-in. Generated code is readable Python you can maintain. You can use GenAI-Logic with any frontend technology or gradually add it to existing Flask applications.

What does it overlap with? (workflow, database, API gateway)

GenAI-Logic overlaps with the data governance layer. It's NOT a workflow engine (use Temporal/Airflow for multi-step orchestration) or complete API gateway (doesn't handle service mesh concerns). It IS the data integrity layer within workflow nodes, the business logic enforcement point behind API gateways, and the commit-time governance supplement to database constraints. Think: "guardrails for business logic" that sit architecturally between application code and database commit.

Is this a black box?

No. Generated code is readable Python in logic/declare_logic.py using a declarative DSL (Rule.sum, Rule.constraint, etc.). You can view rule definitions, edit them directly, debug with standard Python debuggers, and see complete execution traces in logs. The engine's behavior is deterministic and documented—rules fire in dependency order based on data relationships. All source code is open source (Apache 2.0) on GitHub.

How do you test and audit AI-governed logic?

Behave tests verify business requirements map to declarative rules with complete execution traces. The Behave Logic Report shows which rules fired during each test, displaying before→after values for all adjustments and demonstrating the 44X testing advantage—tests verify "what" (business rules) not "how" (procedural paths). This provides requirements traceability from business intent through rules to execution, with deterministic results making test debugging straightforward.

What about performance/scalability? Is this a RETE engine?

Not a RETE engine—no pattern matching or inference, just deterministic dependency execution. Performance characteristics: dependencies computed once at startup (not runtime), rules execute only for changed objects (pruning), adjustments use deltas not full recalculation (efficiency), and old_row tracking enables correct cascading updates. Production deployments handle millions of transactions. The non-RETE architecture trades RETE's flexibility for predictable performance and deterministic behavior suitable for transactional systems.

What's the lock-in risk?

Low. Your database remains standard with no vendor schema requirements. Generated code is readable Python (Flask/SQLAlchemy) using industry-standard tools. Rules are Python code you can read, edit, or remove—not compiled or encrypted. Open source (Apache 2.0) with no runtime fees or enterprise paywalls. Exit path exists: stop using LogicBank, write procedural code instead, keep your database and models with no migration required. You're adopting an architectural pattern, not signing a vendor contract.
