# Specification Quality Checklist: Core AST Structure

**Purpose**: Validate specification completeness and quality before proceeding to planning
**Created**: 2026-02-03
**Feature**: [spec.md](../spec.md)

## Content Quality

- [x] No implementation details (languages, frameworks, APIs)
- [x] Focused on user value and business needs
- [x] Written for non-technical stakeholders
- [x] All mandatory sections completed

## Requirement Completeness

- [x] No [NEEDS CLARIFICATION] markers remain
- [x] Requirements are testable and unambiguous
- [x] Success criteria are measurable
- [x] Success criteria are technology-agnostic (no implementation details)
- [x] All acceptance scenarios are defined
- [x] Edge cases are identified
- [x] Scope is clearly bounded
- [x] Dependencies and assumptions identified

## Feature Readiness

- [x] All functional requirements have clear acceptance criteria
- [x] User scenarios cover primary flows
- [x] Feature meets measurable outcomes defined in Success Criteria
- [x] No implementation details leak into specification

## Validation Results

✅ **All items PASS** - Specification is complete and ready for planning phase.

## Notes

- Specification derives directly from SPRINT_1_REQUIREMENTS.md (TR-1: Core AST Nodes)
- Annotation concepts (DerefStrategy, OptimizationLock, LangSpecific) are included in structure but their behavior is deferred to later features
- Editor rendering requirements are detailed enough to guide implementation without prescribing specific MPS cell models
- Type system includes all required types from requirements plus CustomType for extensibility
- Assumptions document necessary context for downstream features
