Diagnostic Error Code Index

The table below catalogs all compiler diagnostic codes produced by the Scapius parser and semantic analysis suite.

Error Code	Category	Cause	Remediation
NEA1001	Syntax	Parsing syntax error, missing token, unclosed string, or invalid grammar structure	Check DSL syntax against language specification and close any unclosed braces/quotes.
NEA2001	Semantic (AST)	Duplicate entity identifier within workspace	Ensure all entity IDs across all files in the workspace are globally unique snake_case identifiers.
NEA2002	Semantic (AST)	Duplicate view identifier within workspace	Ensure all view IDs across all view blocks are globally unique.
NEA2003	Semantic (AST)	Invalid property path depth in predicate expression	Limit nested property path traversal to supported entity attributes.
NEA2004	Semantic (AST)	Invalid comparison operator for field type	Use string operators (contains, starts_with) for strings and numeric operators (>, <, etc.) for numbers.
NEA2005	Semantic (AST)	Ambiguous predicate literal value	Ensure predicate comparison values clearly match the target field type.
NEA2006	Semantic (AST)	Invalid predicate comparison value	Ensure comparison values match expected formats and enums.
NEA2007	Semantic (AST)	Type mismatch between compared operands	Ensure operands on both sides of the comparison operator have compatible types.
NEA2008	Semantic (AST)	Duplicate text annotation identifier in view	Ensure all text <id> statements inside a view have unique IDs.
NEA2009	Semantic (AST)	Text annotation anchor target entity not found in workspace	Ensure the anchor <target> points to a valid, existing entity identifier.
NEA2010	Semantic (AST)	Text annotation anchored to another text annotation	Anchor annotations to domain entities or views, not other text annotations.
NEA2011	Semantic (AST)	Empty text annotation content	Provide non-empty markdown text content inside the triple-quoted block.
NEA2012	Semantic (AST)	Text annotation declared in a DOM-rendered view	Text annotations are supported only in canvas-rendered diagram views (e.g. landscape, container, threat_model, integration, data_flow, attack_surface).
NEA3001	Semantic Linking	Orphaned relationship target reference (target ID does not exist)	Check spelling of destination entity ID or ensure the target .ea file is included in workspace.
NEA3002	Semantic Linking	Ambiguous reference to multiple symbol candidates	Disambiguate entity reference by qualifying with namespace or fixing duplicate definitions.
NEA3003	Semantic Linking	Duplicate relationship between source and destination with identical verb	Remove the duplicate relationship declaration.
NEA3004	Semantic Linking	Relationship constraint violation (verb disallowed between source/target entity types or multiple composition parents)	Consult the Master Relationship Matrix for allowed source/destination combinations.
NEA3005	Semantic Linking	Cyclic composed_of composition loop detected	Remove cyclic containment loops (an entity cannot be composed of itself).
NEA4001	Domain Validation	Property value is not in the allowed enum value set	Check allowed enum values for the field (e.g. time, risk, criticality, mitigation_status).
NEA4002	Domain Validation	Duplicate lifecycle phase declared on entity	Declare each lifecycle phase (Idea, Plan, Build, Run, Retire) at most once per entity.
NEA4003	Domain Validation	Invalid date format in lifecycle phase	Use ISO-8601 "YYYY-MM-DD" date string format.
NEA4004	Domain Validation	Lifecycle end date occurs before start date	Ensure end date is chronologically greater than or equal to start date.
NEA4005	Domain Validation	Invalid capability hierarchical numbering format	Use standard dotted capability numbering (e.g. "1.2", "2.4.1").
NEA4006	Domain Validation	Capability numbering sequence gap detected	Ensure hierarchical capability numbers follow a contiguous sequence without numbering gaps.
