# Specification Quality Checklist: Multilingual NLP Entity Inherence Classifier

**Purpose**: Validate specification completeness and quality before proceeding to planning
**Created**: 2026-08-19
**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

## Notes

- Initial requirements documented from user audio brief and refined with POC constraints.
- ECP defined as Entity Context Profile with materialized JSON snapshots.
- Tier 1 (deterministic rules) defined as mandatory core; Tier 2 (embeddings) and Tier 3 (LLM) defined as optional/configurable (LLM off by default, no API key required).
- Decision rules explicitly codified for all 4 categories and derived `is_inherent` boolean.
- Success criteria scoped to a controlled 24-case POC benchmark suite (6 languages × 4 decision types).
- Structured error codes defined (`invalid_ecp_json`, `invalid_markdown`, `unsupported_language`, `empty_content`, `missing_required_field`).
- Explicit out-of-scope declarations enforced (No REST API, No package publishing, No queues/workers, No runtime DB/Neo4j).
