Key Architectural Decisions

Adr Id Title Status Rationale
adr-pattern-cas-decoupled-execution-model Decoupled Reasoning and Orchestration Pattern Promotion accepted Foundational for implementation-agnostic workflows and separation of concerns.
adr-038-runtime-capability-inventory Runtime Capability Inventory Adoption accepted Establishes an authoritative state for implemented capabilities beyond raw commit deltas.
adr-030-dashboard-architecture Governance Health and Intelligence Dashboard accepted Provides synthesized visibility via read-only intelligence without modifying source artifacts.
adr-rule-context-builder-define-2026-04-22 Rule Context Builder Implementation accepted Automates manual injection to ensure deterministic governance application.
adr-llm-gateway-integration-adoption-20260505 Hybrid LLM Gateway Integration accepted Ensures provider agnosticism while enforcing structured outputs via Pydantic.

System Evolution

The system is evolving from a template-driven documentation model to a runtime-native Architecture Intelligence Platform. Key changes include the abstraction of the Knowledge Provider to decouple logic from storage, the shift to a standardized Workflow Execution Model (Runner/Workflow/Provider), and the elevation of Architecture Work as the authoritative planning registry. Manual governance is transitioning toward an automated Detect-Analyse-Execute loop to address a 15:1 governance velocity bottleneck.

Intent & Direction

CAS is trending toward 'Continuous Architecture Governance' with a focus on 'Architecture Intelligence'. Future intent centers on end-to-end traceability from Business Intent artifacts to Code implementation, cross-project portfolio intelligence via a Knowledge Graph, and real-time operational governance surfaces. Integration with external enterprise architecture ecosystems and automated drift remediation are primary future milestones.

Pattern Evolution

Emerging Patterns

  • diagram-governance (conditional)
  • pattern-classification-framework (pending)
  • interactive-architecture-intelligence (proposed)
  • external-ingestion-framework (proposed)
  • business-intent-traceability (proposed)
  • pattern-cas-decoupled-execution-model
  • llm-provider-abstraction-boundary
  • dashboard-architecture
  • runtime-capability-inventory

Knowledge System Health

pattern_coverage: medium governance_backlog: 22 consistency_score: medium findings: Significant 'Persistence Lag' identified where implementation status is 'DONE' but formal ADRs remain 'proposed' or 'pending'. 'Excessive Backlog Pressure' exists with 22 unprogressed proposals, signaling that intelligence generation outpaces human validation capacity.
