Rules & Constraints

Active architectural constraints and governance rules.

Rule	Category	Status	Compliance	Summary
Workflow Execution Model Compliance	execution	active	Disabled	All runtime-native workflows must conform to the CAS Workflow Execution Model and its separation-of-concerns principles.
ADR as Single Source of Truth	governance	active	Enabled	Architecture decisions must be recorded and updated only in decision records (ADR); all other representations must be derived from ADR.
AEM Consistency with Decisions	governance	active	Disabled	Ensure AEM reflects and does not contradict ADR decisions.
Core Patterns Must Be Foundational	governance	active	Disabled	Core patterns must represent foundational architectural primitives, not specific strategies or implementations.
Language & Semantics Contract	governance	active	Disabled	Defines the semantic contract for language used in architecture artefacts to ensure clarity, consistency, and alignment across the system design lifecycle.
Pattern and Decision Lifecycle Alignment	governance	active	Enabled	Ensure consistent interpretation between pattern maturity and decision lifecycle.
Promotion Requires Evidence	governance	active	Disabled	Pattern promotion to core must be supported by strong evidence, preferably from multiple sources or systems.
Rule Precedence Hierarchy	governance	active	Disabled	Defines the precedence model for resolving conflicts between global, project, and prompt-level rules.
System Proposes, Architect Decides	governance	active	Disabled	All architectural decisions must be proposed by the system and explicitly accepted, rejected, or deferred by an architect.
rule-architecture-work-authority	governance	N/A	Disabled	No summary provided.
rule-generated-artifacts-not-authoritative	governance	N/A	Disabled	No summary provided.
rule-signal-promotion-criteria	governance	N/A	Disabled	No summary provided.
Decision Status Drives Stage	lifecycle	active	Disabled	The lifecycle stage of any architecture item must be derived from its decision status; items with decision.status != 'accepted' must not be marked as DONE.
Decisions Must Be Persisted	lifecycle	active	Disabled	All architectural decisions must be persisted as structured decision records (ADR) before being reflected in AEM or other artefacts.
Patterns Must Be Created as Supporting	lifecycle	active	Disabled	All patterns must be created as supporting by default and never directly as core.
Decision Schema Must Be Structured	quality	active	Enabled	All decisions must be expressed using a structured YAML decision schema and not as unstructured narrative text.
Heuristic-Derived Patterns Require Signals	quality	active	Disabled	All heuristic-derived patterns must include at least one linked signal as evidence.
Do Not Merge Across Architectural Layers	structural	active	Disabled	Patterns must not be merged or consolidated across different architectural layers.
rule-shared-knowledge-workspace	structural	N/A	Disabled	No summary provided.
