Purpose Reminder​

A Wrekenfile models semantic callables and workflows for SDKs and APIs. The Wreken spec is not a language spec, runtime spec, or UI spec.

Rule of thumb: If something doesn't help an LLM plan or generate correct end-to-end workflows, it's probably out of scope.

1. Language-Level Mechanics (Explicitly Not Modeled)​

These vary wildly by language and do not improve semantic reasoning.

  • Generics / type parameters (<T>, where T : …)
  • Ownership, lifetimes (Rust)
  • Memory management
  • Visibility (public, private, protected)
  • Interfaces vs abstract classes
  • Traits, mixins
  • Macros
  • Annotations / decorators / attributes
  • Operator overloading
  • Reflection / metaprogramming

Why: They affect how code compiles, not what the callable does.

2. Execution & Runtime Policy (Intentionally Excluded)​

These belong to runtime or orchestration layers, not the spec.

  • Retries & retry strategies
  • Backoff algorithms
  • Timeouts
  • Circuit breakers
  • Threading / concurrency limits
  • Connection pooling
  • Resource cleanup / disposal semantics
  • Caching behavior
  • Performance tuning

Why: They are operational policy, not semantic intent.

3. UI / Presentation Layer (Hard No)​

Wrekenfile does not model rendering or interaction.

  • UI components (React / Vue / Angular)
  • JSX / templates
  • DOM manipulation
  • Styling / CSS
  • Event handlers (onClick, onSubmit)
  • Component lifecycle hooks
  • Layout logic

Rule of thumb: If it renders something → out of scope.

4. Language-Specific Syntax & Imports​

By design, these never appear.

  • import, require, using
  • new, await, async
  • .then(), callbacks
  • Inline executable code

Why: Wrekenfile is syntax-free by contract.

5. Detailed Transport Configuration​

Transport is modeled semantically, not exhaustively.

Not Covered:​

  • TLS configuration
  • Proxy configuration
  • HTTP client tuning
  • Compression settings
  • Keep-alive tuning

Covered:​

  • HTTP method, endpoint, headers, body type
  • Async vs sync semantics
  • Streaming vs non-streaming

6. Auth & Security Internals​

Auth is modeled as flows + requirements, not mechanisms.

Not Covered:​

  • Token storage strategy
  • Secure key management
  • Automatic token refresh rules
  • Scope negotiation logic
  • MFA / device trust logic
  • Permission evaluation

Covered:​

  • Auth methods (login, token exchange)
  • Auth requirements (REQUIRES, headers)
  • Errors

7. Business Rules & Domain Validation​

Wrekenfile does not encode business logic.

  • Field-level validation rules (amount > 0)
  • Conditional constraints
  • Cross-field dependencies
  • Domain invariants
  • Pricing rules
  • Regulatory logic

Why: These belong to domain models or validation layers.

8. Versioning Strategy & Migration Logic​

  • API version negotiation
  • Backward compatibility rules
  • Deprecation timelines
  • Migration helpers

Handled instead by:

  • Separate Wrekenfiles per version
  • Different SOURCES

9. Testing Semantics (Beyond NLP Prompts)​

Wrekenfile tests are descriptive, not executable.

Not Covered:​

  • Assertion syntax
  • Mocking frameworks
  • Test runners
  • Coverage metrics
  • Property-based testing

10. What This Means Practically​

Wrekenfile IS:​

  • A semantic IR for SDKs & APIs
  • Workflow-first
  • LLM-optimized
  • Language-agnostic
  • Deterministic

Wrekenfile IS NOT:​

  • An SDK replacement
  • A runtime engine
  • A UI framework
  • A policy engine
  • A compiler IR
