Current Architecture State

Generated intelligence — derived from authoritative governance artifacts. Not a source of truth.

Executive Summary

CAS is in a template-stable, operationally governed, and partially aligned state. The project has moved decisively out of the 2024-05-20 "template-ready, no live governance evidence" baseline and into an actively governed baseline defined by:

  • A persistent Architecture Work Registry that now holds authoritative planning state.
  • A standardised CAS Workflow Execution Model (Runner orchestrates, Workflow reasons, Knowledge Provider supplies context) — accepted, operational.
  • Runtime-native Architecture Work generation (conversation-to-aw, discovery-to-aw, vision-to-aw) — operational.
  • A continuously produced Architecture Evolution Map (AEM), Architecture Intent Document (AID), and Alignment Report chain — six consecutive AEM versions, five AID versions, five alignment reports.
  • 21 active architecture lineage capabilities (reasoning, governance, steering, observability, semantic contracts, provider abstraction).
  • 11 ADRs persisted in the global knowledge layer — 5 accepted, 5 pending, 1 rejected.

The system is bottlenecked by a governance velocity gap (30 proposed Architecture Work items vs 2 accepted in the current AEM) and a structured-decision schema non-compliance (legacy ADRs remain narrative; rule-decision-schema-must-be-structured is in READY, not yet accepted). The Core Orchestration Pipeline still lacks its foundational ADR.

Alignment status is partially_aligned with 0 critical, 3 high, and 3 medium findings. The dominant theme is governance backlog processing, not architectural fragility.

  • Summary: Generated architectural dashboard derived from authoritative artifacts (Architecture Work, ADRs, baseline).

Architecture Intent Document (AID)

  • Status: operational
  • Confidence: High
  • Evidence: Five AID artifacts (aid-2026-05-25 through aid-2026-06-06); rule-language-semantic-contract ("align with", not "reflect") enforced.
  • Summary: Continuously produced architectural intent that aligns with — but does not reflect — system state.

  • Evidence: Lineage capabilities cap-steering-projection-steering-8499834eb7e4 and cap-orchestration-governance-steering-projection-7dda2a74c1c3; dedicated flow steering-projection-flow; CI workflow cas-managed-steering-sync.yml.
  • Summary: Git delta → knowledge artefact projection, executed through the runner and surfaced via a dedicated end-to-end diagram.

Architecture Lineage

  • Status: active
  • Confidence: High
  • Evidence: knowledge/projects/ideas-to-life-cas/capabilities/lineage.yaml tracks 21 active capabilities with modification timestamps; lineage is updated as part of normal workflow execution.
  • Summary: Core runtime modules include active lineage tracking to ensure integrity of architectural decisions and knowledge artifacts.

Observability / Telemetry

  • Status: active
  • Confidence: High

  • Confidence: High
  • Evidence: AEM [READY] Transition to Structured Decision Governance (YAML schema); aw-2026-06-06-01 (proposed); global rule rule-decision-schema-must-be-structured active; alignment report flags this as a HIGH finding.
  • Summary: Schema for ADRs is defined; existing 11 ADRs have not been migrated, leaving an active rule violation.

Initiative Landscape

Proposed

  • Architecture Work Registry — Architecture Work is the authoritative backlog; structural evolution of templates, ingestion, and governance model in progress.
  • Governance Foundation (YAML ADRs) — Transition narrative ADRs to structured YAML; align with rule-decision-schema-must-be-structured.
  • Pattern Lifecycle Management — Evidence-based promotion framework from supporting to core patterns (rule-patterns-born-as-supporting, rule-heuristic-patterns-require-signals).
  • Business Intent Integration — First-class business intent signals and traceability (aw-2026-05-31-006).
  • Code Intelligence — Structural analysis, drift detection, and AID-vs-code comparison (aw-2026-05-31-007).
  • AI Agent Skill Enforcement CI — Automated CI validation enforcing CAS skill compliance on PRs.

Active

  • Architecture Work Registry rollout — In operational use by the runner; producer flows live.
  • Steering Projection — Daily driver of knowledge artifact updates from git deltas.
  • ReasoningOps / GovernanceOps conceptual rollout — Concepts validated through runtime behaviour; not yet formalised as governed capabilities.

Completed

  • CAS Workflow Execution Model — Accepted and operational (aw-2026-06-06-04).
  • Runtime-native Architecture Work generation — Done (aw-2026-06-06-05).
  • Discovery Flow initial runs — First four discovery flows produced aw-discovery-ideas-to-life-cas-1..4.
  • Dashboard architecture decision — adr-030-dashboard-architecture accepted on 2026-06-04.

Superseded

  • Dual-path routing — Demoted by adr-dual-path-routing-demote-2026-04-20 (status: rejected).
  • Multimodal expansion before stabilisation — Explicitly rejected by adr-stabilise-core-loop-before-multimodal-keep-2026-04-20 (status: proposed, forum_status: accepted).

Governance State

CAS governance is in transition from a template-ready, manually-triggered model to an operationally governed, rules-driven model.

  • Authoritative artifacts: ADRs (11), Architecture Work (41 instances in work/, of which 30 are proposed), AEM (6 daily versions), AID (5 versions), Alignment Reports (5 versions).
  • Rule set: 19 global rules active in the alignment engine; rule conflicts and prompt-rule audit reports produced (5 conflict reports, 4 prompt audits).
  • Lifecycle coverage: All governance artifacts carry schema-validated frontmatter; rule precedence hierarchy enforced (rule-precedence-hierarchy); no project-scoped rules exist.
  • Provenance: Architecture Work is now the planning source of truth; AEM and AID are derived.
  • Human-in-the-loop: Enforced by rule-system-proposes-architect-decides and rule-decision-status-drives-stage.

Governance maturity: Emerging → Active. Structure is in place; velocity is constrained by the proposal backlog and a schema-compliance gap.

Architecture State

Major architectural structures, models, and patterns currently in operation:

  • Workflow Execution Model — Runner / Workflow / Knowledge Provider separation, with ReasoningExecutionContract mediating prompt-to-LLM interaction.
  • Architecture Knowledge Layer — knowledge/global/ and knowledge/projects/<project>/ partitioning, with templates, rules, patterns, decisions, maps, intent, alignment, and ingestion directories.
  • Architecture Work Registry — Persistent, schema-validated planning layer.
  • AEM / AID / Alignment chain — Generated governance dashboard artifacts.
  • Rules Context Loader — Loads global and project rules into the reasoning context at execution time.
  • Steering Projection — Git delta → knowledge artifact pipeline (steering-projection-flow).
  • LLM Provider Abstraction — Provider-agnostic LLM boundary with structured output.
  • Pattern Catalogue — 17 patterns persisted as global architecture knowledge.
  • Architecture Lineage — Module-level capability tracking via capabilities/lineage.yaml.

Established patterns (representative): architecture-workflow-loop, build-time-governance, contract-first-architecture, deterministic-core-selective-augmentation, heuristic-driven-arbitration, llm-provider-abstraction-boundary, orchestrator-managed-pipeline, prompt-as-code-separation, prompt-schema-contracts-as-architecture, structured-output-via-schema, typed-execution-context.

Intelligence State

  • Available intelligence capabilities:
  • Architecture Work generation (conversation / discovery / vision / alignment producers).
  • AEM regeneration from authoritative artifacts.
  • AID synthesis aligned with system state.
  • Alignment analysis applying the full rule context.
  • Rule audits (prompt-rules-audit-*) and rule conflict reports (rule-conflicts-*).
  • Architecture lineage tracking (21 active capabilities).
  • Heuristic governance health model (Dashboard ADR-030).
  • Planned / not yet operational:
  • Code intelligence (structural analysis, drift detection).
  • Business intent signal extraction and traceability.
  • Interactive Architecture Intelligence Map (AIM).
  • Knowledge Graph layer for cross-project queries.

Operational State

  • Operational governance capabilities: Rules-driven alignment analysis, daily AEM regeneration, daily AID synthesis, daily steering projection, governance audits, schema-validated frontmatter across artifacts.
  • Automation capabilities: Runtime-native Architecture Work generation (operational), CI workflows cas-managed-steering-sync.yml and cas-portal-publish.yml (active), cas run <flow> orchestration CLI (active), lineage tracking (automatic).
  • Operational governance maturity: Emerging. Automation exists for the core loop (Runner + AEM + AID + Alignment + AW); enforcement automation (CI validation enforcing CAS skill compliance) is proposed but not yet implemented.
  • Trust calibration: Heuristic governance health model is the approved Phase 1 mechanism (ADR-030), and the dashboard is read-only intelligence.

Strategic Gaps

Evidence-backed gaps between current and intended architecture:

  1. YAML ADR migration is incomplete. rule-decision-schema-must-be-structured is active; 11 ADRs persist as narrative Markdown. (Alignment HIGH; aw-2026-06-06-01 proposed; AEM READY.)
  2. Core Orchestration Pipeline ADR is missing. Foundational decision provenance for the orchestration pipeline is absent. (Alignment HIGH; aw-2026-06-06-02 proposed; AEM READY.)
  3. Governance velocity bottleneck. 30 Architecture Work proposals vs 2 accepted in the current AEM (proposed:accepted ratio of 15:1, exceeding the 5:1 heuristic threshold from the AID). (Alignment HIGH; AID risk.)
  4. Automated CI validation for CAS skills is absent. No enforced guardrail at PR time. (Alignment MEDIUM; AID risk.)
  5. Business Intent knowledge model is absent. Traceability from business requirement → ADR → pattern → code is not yet possible. (Alignment MEDIUM; aw-2026-05-31-006 proposed.)
  6. Code Intelligence is absent. No structural code analysis, no automated drift detection. (AID long-term roadmap; aw-2026-05-31-007 proposed.)
  7. AID/AEM business_traceability coverage is low. (AID coverage field.)
  8. Project-scoped rules layer is empty. All rules are global; knowledge/projects/*/rules/ is unused. (Rule conflict report note.)

Confidence Assessment

Strong evidence

  • Workflow Execution Model adoption (acceptance + completion AW + AEM DONE).
  • Architecture Work Registry as authoritative backlog (acceptance + lineage).
  • AEM / AID / Alignment daily regeneration (six/five/five consecutive artifacts).
  • Architecture Work runtime generation (completed AW + AEM DONE).
  • 21 active lineage capabilities.
  • Dashboard layered architecture (ADR-030 accepted).
  • Rule precedence hierarchy and human-in-the-loop governance (active rules).

Uncertain areas

  • Effective governance throughput once the 30-item proposal backlog is processed (heuristic only).
  • Live runtime status of the Governance Health Dashboard (ADR accepted, runtime delivery not yet confirmed in AEM).
  • Maturity of LLM gateway integration (ADR pending, no operational evidence).
  • Coverage of the prompt-rule audit cleanup (issues flagged; no completion artifact in evidence).

Missing evidence

  • No Architecture Work signal-layer evidence for emergent patterns.
  • No project-scoped rules evidence (knowledge/projects/*/rules/ is empty).
  • No active measurement of drift between AID and code (no Code Intelligence yet).
  • No measurement of cross-project signals or AEMs (single project in scope).
  • No recorded evidence that the proposed AEM READY actions (initial discovery flow, core orchestration ADR, YAML schema transition) have been moved to APPROVED/DONE within the captured artifacts.
