 ===== Requirement Identifiers ===== ===== Requirement Identifiers =====
  
-DIDO-TE uses the following requirement-class identifiers:+Each requirement has a stable requirement identifier.
  
-^ Requirement Class ^ Prefix ^ +The requirement identifier identifies the requirement independently of its location within the requirements hierarchy. Moving a requirement to another category or namespace does not, by itself, change the requirement identifier.
-| Mission Objective | ''MO'' | +
-| Operational Requirement | ''OR'' | +
-| Functional Requirement | ''FR'' | +
-| Security Requirement | ''SEC'' | +
-| Logging and Auditing Requirement | ''LOG'' | +
-| Reliability Requirement | ''REL'' | +
-| Performance Requirement | ''PER'' | +
-| Maintainability Requirement | ''MNT'' | +
-| Data Management Requirement | ''DAT'' | +
-| Interoperability Requirement | ''INT'' | +
-| Future Capability Requirement | ''FUT'' | +
-| Key Value Proposition Requirement | ''KVP'' |+
  
-Each requirement identifier consists of the requirement-class prefix followed by a three-digit number.+For example, a Node requirement identified as ''NOD-013'' remains ''NOD-013'' if the Node Requirements namespace is relocated within Annex C.
  
-Examples include:+Requirement identifiers SHALL NOT be reused for a different requirement after assignment.
  
-  * ''MO-001'' +A requirement that is withdrawn, deprecated, or superseded retains its identifier and governance history.
-  * ''OR-001'' +
-  * ''FR-001'' +
-  * ''SEC-001'' +
-  * ''PER-001''+
  
-A requirement identifier remains stable when the requirement moves to another section or undergoes an editorial revision that does not substantively change the requirement.+===== Requirement Prefixes =====
  
-A retired, withdrawn, deprecated, or superseded identifier is not reassigned to another requirement.+Requirement identifiers use a controlled prefix that identifies the requirement family.
  
-===== Requirement Decomposition =====+The prefix identifies the subject area of the requirement and remains stable even if the requirement is moved within the Annex C hierarchy. 
 + 
 +^ Prefix ^ Requirement Category ^ 
 +| MO | Mission Objective | 
 +| OPR | Operational Requirement | 
 +| ENV | Test Environment Requirement | 
 +| NOD | Node Requirement | 
 +| TWIN | Twin Node Requirement | 
 +| NET | Virtual Network and Communication Requirement | 
 +| STC | State and Time Control Requirement | 
 +| TDF | Test Definition Requirement | 
 +| TEX | Test Execution Requirement | 
 +| RPB | Record and Playback Requirement | 
 +| BLC | Baseline and Comparison Requirement | 
 +| VAL | Validation Requirement | 
 +| EVD | Monitoring and Evidence Requirement | 
 +| CAT | Catalog and Reuse Requirement | 
 +| SEC | Security Requirement | 
 +| AUD | Logging and Auditing Requirement | 
 +| REL | Reliability Requirement |

 +| CON | Conformance Requirement | 
 + 
 +Requirement identifiers use the form: 
 + 
 +<code> 
 +PREFIX-NNN 
 +</code>
  
-Each normative requirement expresses one independently interpretable and independently verifiable obligation.+where:
  
-When a source requirement contains multiple normative obligations, Annex C preserves the source requirement on a non-leaf parent page and assigns a lowercase suffix to each derived requirement.+  * ''PREFIX'' identifies the requirement family 
 +  * ''NNN'' is a sequential identifier within that family
  
 For example: For example:
  
-  * ''FR-040'' identifies the source requirement represented by the parent page +<code> 
-  * ''FR-040a'' identifies the first derived requirement +ENV-001 
-  * ''FR-040b'' identifies the second derived requirement+NOD-013 
 +TEX-004 
 +SEC-002 
 +</code>
  
-The non-leaf parent page retains a trailing '':start'' in its namespace. Each derived leaf requirement omits the trailing '':start''.+A requirement prefix SHALL NOT change solely because the requirement page or requirement category is reorganized within Annex C.
  
-A derived requirement includes a **Derived From** section that identifies:+A retired or superseded requirement identifier SHALL NOT be reassigned to a different requirement.
  
-  * The parent requirement +===== Requirement Decomposition ===== 
-  * The Original Requirement + 
-  * The obligation preserved by the derived requirement +A source requirement may contain multiple independently verifiable obligations. 
-  * Other requirements derived from the same parent requirement+ 
 +A source requirement containing multiple independently verifiable obligations may be decomposed into multiple requirements when decomposition improves atomicity, clarity, traceability, or verification. 
 + 
 +Derived requirements preserve traceability to the source requirement, architectural concept, model element, or other authoritative basis from which they were derived. 
 + 
 +Decomposition SHALL NOT change the approved intent of the source obligation. 
 + 
 +A derived requirement does not acquire independent authority merely because it has been decomposed from another statement. Its authority remains traceable to its source and applicable governance process. 
 + 
 +===== Source and Derivation Traceability ===== 
 + 
 +Each requirement identifies its authoritative source or derivation basis where applicable. 
 + 
 +A requirement may originate from: 
 + 
 +  * A source requirement 
 +  * A normative specification or other controlled document 
 +  * A policy or governed constraint 
 +  * A conceptual or logical model 
 +  * An architectural decomposition 
 +  * An approved governance determination 
 +  * Another requirement 
 + 
 +Source material may be normalized when necessary to produce an atomic, clear, verifiable requirement. 
 + 
 +Normalization may correct: 
 + 
 +  * Terminology 
 +  * Grammar 
 +  * Active or passive voice 
 +  * Normative modality 
 +  * Ambiguous subjects 
 +  * Compound obligations 
 +  * Undefined references 
 +  * Implementation-specific wording that is inappropriate at the architectural level 
 + 
 +Normalization SHALL preserve the source's approved intent. 
 + 
 +The applicable governance process SHALL approve a material change in requirement intent.
  
-A requirement that does not require decomposition uses a **Source** section rather than a **Derived From** section.+Editorial normalization SHALL NOT introduce a material change in intent.
  
 ===== Requirement Page Structure ===== ===== Requirement Page Structure =====
  
-Each leaf requirement page uses the following sections where applicable:+Each requirement page uses the following sections where applicable:
  
   * Statement   * Statement
   * Source   * Source
-  * Derived From 
   * Rationale   * Rationale
   * Applies To   * Applies To
   * Verification   * Verification
-  * Referenced By+  * Traceability 
 +  * ConOps Relationship
   * Delivery Phase   * Delivery Phase
-  * Implementation Status 
   * Requirement Status   * Requirement Status
-  * Issues 
-  * Notes for Editors 
  
-The **Source** and **Derived From** sections are mutually exclusive.+A leaf requirement page contains an independently verifiable normative obligation and therefore includes a ''Statement'' section and a ''Verification'' section.
  
-A requirement page uses **Source** when the requirement does not result from the decomposition of another requirement.+A non-leaf requirement page organizes subordinate requirements and does not establish a separate conformance obligation unless explicitly stated otherwise. A non-leaf requirement page therefore normally omits ''Statement'' and ''Verification'' sections.
  
-A requirement page uses **Derived From** only when the requirement results from the decomposition of a parent requirement.+Additional sections SHALL NOT be added to individual requirement pages merely to duplicate information maintained through backlinks, traceability records, or another authoritative register.
  
 ===== Normative Language ===== ===== Normative Language =====
  
-Requirement Statements use the following normative terms:+Requirement statements use the following normative terms:
  
   * **SHALL** identifies a mandatory requirement   * **SHALL** identifies a mandatory requirement
   * **SHALL NOT** identifies a mandatory prohibition   * **SHALL NOT** identifies a mandatory prohibition
   * **MAY** identifies a permitted capability or action   * **MAY** identifies a permitted capability or action
-  * **SHOULD** identifies an advisory recommendation+  * **SHOULD** identifies a recommendation when advisory language remains appropriate
  
-The Statement section contains only the normative requirement.+Normative modal verbs are written in uppercase.
  
-Rationale, examples, implementation information, verification information, source information, and editorial guidance remain outside the Statement section.+A requirement page may editorially correct source wording for terminology, atomicity, clarity, active voice, normative style, or verification without changing the approved intent of the requirement.
  
 ===== Requirement Quality ===== ===== Requirement Quality =====
  
-Each DIDO-TE requirement conforms to the applicable CWE and SDA rules.+Requirements are reviewed for specification quality before approval.
  
-Each requirement:+Requirement review examines characteristics including:
  
-  * Has a unique and stable identifier +  * Atomicity 
-  * Expresses a single, independently interpretable obligation +  * Clear identification of the responsible subject 
-  * Identifies the responsible actor +  * Defined terminology 
-  * Identifies the required behavior, outcome, permission, or prohibition +  * Appropriate normative modality 
-  * Uses defined terminology consistently +  * Active voice 
-  * Uses explicit normative language +  * Unambiguous scope 
-  * Avoids vague, weak, open-ended, and logically ambiguous expressions +  * Verifiability 
-  * Avoids implementation-specific mechanisms unless the mechanism constitutes an approved constraint +  * Traceability 
-  * Supports objective verification +  * Consistency with related requirements 
-  * Preserves traceability to the source material +  * Absence of unnecessary implementation constraints 
-  * Preserves traceability to architecture, implementation, test, Evidence, and conformance artifacts+  * Absence of unresolved conflicts or ambiguous precedence 
 + 
 +Specification Discipline and Authoring (SDA) identifies candidate weaknesses in requirement wording, structure, terminology, traceability, or semantics. 
 + 
 +The Common Specification Weakness Enumeration (CWE) evaluates candidate findings, confirms applicable defects, and records their classification, severity, governing rule, and applicable defect pattern. 
 + 
 +Automated or AI-assisted analysis may identify, compare, trace, or propose corrections to candidate issues. 
 + 
 +Automated or AI-assisted analysis SHALL NOT resolve conflicts, ambiguities, or precedence among governed requirements, policies, specifications, profiles, or other authoritative constraints. 
 + 
 +A conflict, ambiguity, or unresolved precedence among governed requirements, policies, specifications, profiles, or other authoritative constraints SHALL be referred to the appropriate governance authority through the applicable Community of Interest (CoI) structure.
  
 ===== Requirement Status ===== ===== Requirement Status =====

-===== Implementation Status =====+Requirement Status describes the requirement's authority and lifecycle state. It does not describe whether a particular product or implementation satisfies the requirement.
  
-Implementation Status identifies the state of DIDO-TE relative to the requirement.+===== Realization and Implementation Status =====
  
-Possible states include:+Requirements in this annex are product-neutral and may be realized by one or more architectural capabilities, Reference Architectures, products, services, or implementations. 
 + 
 +The canonical requirement does not prescribe a specific realization unless such a constraint forms part of the approved requirement. 
 + 
 +Traceability records maintain relationships between canonical requirements and their realizations. 
 + 
 +The applicable realization maintains Implementation Status. Implementation Status is not a property of the canonical requirement. 
 + 
 +A realization may identify its relationship to a requirement using implementation states such as:

-===== Notes for Editors ===== 
  
-Annex C is the authoritative source for DIDO-TE normative requirements. +===== Notes for Editors =====
- +
-The draft Requirements Register remains source material. Its ''REQ-0001'' through ''REQ-0091'' identifiers remain source-reference identifiers and do not become canonical DIDO-TE requirement identifiers. +
- +
-Do not change an assigned requirement identifier because the requirement moves to another section. +
- +
-Do not reuse an identifier assigned to a retired, withdrawn, deprecated, or superseded requirement. +
- +
-Apply SDA pattern detection before performing CWE evaluation. +
- +
-Preserve traceability from each DIDO-TE requirement to: +
- +
-  * The source requirement +
-  * Supporting source material +
-  * Applicable ConOps scenarios +
-  * Applicable architecture sections +
-  * Implementation artifacts +
-  * Verification activities +
-  * Verification results +
-  * Evidence +
-  * Identified issues +
- +
-Use a non-leaf parent page only when requirement decomposition requires one.+
  
-Leaf requirement pages omit a trailing '':start'' from their namespaces.+<todo>Remove the explicit creation links under Contents after all planned requirement-category pages have been created and the indexmenu discovers them.</todo>
  
-Non-leaf requirement pages retain a trailing '':start'' in their namespaces.+Preserve stable requirement identifiers when moving or reorganizing requirement pages.
  
-Do not rename a requirement page after an external citation unless a redirect or move plan is in place.+Do not allocate canonical requirements directly to Crucible, DevSecOps, or another realization within the requirement Statement. Maintain realization relationships through Traceability.
