ence between Flux and AMIS lies in how values are expressed. Flux replaces AMIS's parallel field strategy with a Unified Value Semantics model, where the compiler—not the schema author—determines whether a value is static, dynamic, or templated.

AMIS Approach (Legacy)

Every property requiring dynamic control is split into two fields: a static variant and an expression variant with an On suffix (disabled / disabledOn, visible / visibleOn, required / requiredOn). This externalizes a value-level judgment to the object structure, forcing structural changes during extension and relying on undocumented conventions to prevent conflicts.

Flux Approach (Unified)

disabled remains disabled. It can be a static boolean true, an expression ${$form.submitting}, or a template string "${name} is disabled". The compiler analyzes the value at build time, determines its node kind, and generates the appropriate runtime wrapper.

Compile-Time Type System:

type CompiledValueNode<T> =
  | { kind: 'static-node'; value: T }
  | { kind: 'expression-node'; source: string; compiled: CompiledExpression<T> }
  | { kind: 'template-node'; source: string; compiled: CompiledStringTemplate<T> }
  | { kind: 'array-node'; items: CompiledValueNode[] }
  | { kind: 'object-node'; keys: string[]; entries: Record<string, CompiledValueNode> };

Runtime Execution Wrapper:

type CompiledRuntimeValue<T> =
  | { kind: 'static'; isStatic: true; node: StaticValueNode<T>; value: T }
  | {
      kind: 'dynamic';
      isStatic: false;
      node: DynamicValueNode<T>;
      createState(): RuntimeValueState<T>;
      exec(context, env, state): ValueEvaluationResult<T>;
    };

At compile time, the compiler analyzes each field's value, determines its node kind, and wraps it into CompiledRuntimeValue. Static nodes are wrapped as StaticRuntimeValue (zero-cost return). Dynamic nodes are wrapped as DynamicRuntimeValue (carrying evaluation closure and state tracking). CompiledValueNode at compile time is a pure data tree; CompiledRuntimeValue at runtime is an executable wrapper. Expression compilation also performs automatic optimization: if the expression's value is static, it is inlined directly; otherwise, it is wrapped in a reactive dependency tracker.

Architectural Layering: Flux is the rendering layer of the Nop platform, not a standalone framework. The Nop platform, based on reversible computing principles, handles structural transformations before the schema reaches the renderer: i18n substitution, permission pruning, module decomposition/inheritance, and compile-time metaprogramming. These concerns are resolved at the JSON structure level without frontend runtime dependencies. Problems solvable at the structural transformation layer are never carried into the rendering runtime.

AI-Generation Design Assumption: Flux assumes schemas are primarily AI-generated. This drives explicit styling systems, tolerance for schema redundancy, and deterministic interfaces. Explicit declarations are more reliable for AI generation and human review than implicit conventions. The framework remains usable for hand-authored schemas but optimizes for predictability over brevity.

Pitfall Guide

1. Splitting Static/Dynamic Fields: Avoid creating parallel field names (disabled/disabledOn). Unify under a single field and let the compiler infer the node type. Splitting fields forces schema authors to memorize syntax rules and creates mutual-exclusivity validation gaps.
2. Overloading the Store with Behavior: Do not attach API calls, dialog management, or business logic to the data store. Separate reactive state containers from command handlers. Mixing data and behavior in MST stores creates unpredictable side-effects and breaks devtools debugging.
3. Props Drilling for System Context: Stop passing store, env, data, and render functions through intermediate React props. Use context providers or compile-time injection. Props drilling inflates interfaces, increases coupling, and triggers unnecessary re-renders.
4. Relying on Runtime Regex for Expressions: Avoid runtime string parsing (getExprProperties). Shift to compile-time AST analysis. Runtime regex evaluation adds 3-5ms latency per component and prevents static optimization.
5. Implicit Schema Conventions for AI Generation: AI models struggle with implicit defaults and undocumented suffix rules. Prefer explicit, deterministic interfaces. Tolerate schema redundancy to ensure predictable generation and easier human review.
6. Carrying Structural Concerns into the Rendering Runtime: Handle i18n, permissions, and module decomposition at the platform/JSON transformation layer. Polluting the renderer with structural logic breaks framework agnosticism and increases bundle size.
