3. Specification Writing Standards
3.1. Requirement Verification Methods
3.2. Requirement Priority Definitions
3.3. Quality Rules & Specifications
3.3.1. RFC 2119 Keyword Usage
The author MUST write all compliance keywords (MUST, MUST NOT, SHOULD, SHOULD NOT, MAY) in uppercase letters.
The author MUST NOT use ambiguous terms such as generally, fast, ideally, or user-friendly within a specification description.
The implementation team SHOULD document a technical justification whenever a SHOULD or SHOULD NOT requirement is bypassed.
3.3.2. Sentence Structure and Architecture
Each specification description MUST contain exactly one unique requirement.
The author MUST write specification descriptions using the active voice.
The author MUST structure every specification sentence using the sequence: [Subject] + [Keyword] + [Active Verb] + [Measurable Target or Condition].
The length of a specification description sentence SHOULD NOT exceed 15 words.
3.3.3. Metrics and Quantifiable Data
Every performance or physical criterion MUST include a quantifiable, testable numerical value.
The author MUST express all physical units of measurement using the International System of Units (SI).
The author SHOULD use standard mathematical symbols (e.g., ≤, ≥, ±) to define acceptable boundary limits and tolerances.
3.3.4. Identification and Labeling Rules
The author MUST assign a unique identifier to every specification item across all project documentation that strictly matches the regular expression structure: ^[A-Z]{4,5}-OB-[0-9]{3,4}$.
The author MUST restrict the prefix of requirements to one of the exact six system tokens defined in the Nomenclature Standard: RULE-OB-, GAME-OB-, REQ-OB-, SPEC-OB-, PLAN-OB-, or TEST-OB-.
The author MUST format the numeric ID variable as a sequential integer left-padded with zeros up to a minimum length of three digits.
3.3.5. Version Control and Lifecycle Management
The author MUST NOT reuse or reassign the ID of a deleted or deprecated specification.
The author MUST update the STATUS field to Deprecated when a specification is retired from the project scope.
The author MUST increment the version number by a step of 0.1 for minor cosmetic changes and by 1.0 for major technical modifications.
The author MUST provide non-empty values for RATIONALE, DEPENDENCIES, and VERIFICATION_METHOD within every specification item.
