SDS-013: Semantic Execution System Architecture

Document Type

Software Design Specification (SDS) - System Architecture

Status

Draft

Purpose

Defines the high-level architecture of the Semantic Execution Stack, a computational paradigm where “meaning” (semantics) is the single source of truth, and code, infrastructure, and AI behavior are isomorphic projections.

Strategic Context: For the business vision and long-horizon implications, see VISION-002: Unified System Synthesis.

1. System Context (Level 1)

System Name: Isomorphic Semantic Execution System (ISES)

Primary Actors:

• Human Sovereign: Defines intent and signs off on high-level policies.
• Domain Expert: Models the domain semantics (Entities, Flows).
• AI Agents: Constrained execution units that reason within the semantic boundaries.

Core Subsystems:

1. SEA™ (Semantic Execution Architecture): The operating substrate that makes semantics executable.
2. DomainForge™: The meaning definition engine (Canonicalizer).
3. VibesPro™: The projection and synthesis engine (Compiler).
4. GovernedSpeed™: The policy enforcement plane.
5. IAGPM: Governance air traffic control (NIST/ISO/PMI-framed decision rituals).

2. Container Architecture (Level 2)

3. Component Architecture (Level 3)

3.1 DomainForge™ - The Semantic Brain

The canonical domain model and truth source for what the business is and does.

Role in System: Single source of truth for business/domain model. “Schema of meaning” that everything else must obey.

3.2 SEA™ - The Sentient Operating System

The runtime & control plane where models, rules, architectures, agents, and feedback live.

Role in System: Governance engine deciding what’s allowed to change. Memory & reflection layer for system self-awareness.

3.3 VibesPro™ - The Hexagonal Body Builder

The code synthesis & monorepo machine that generates implementations.

Role in System: Reads DomainForge/SEA™ model via port-spec JSON, produces implementations SEA™ can introspect and govern.

3.4 GovernedSpeed™ - Runtime Delivery Guardrails

Pipelines, policies, and metrics ensuring safe, compliant delivery.

3.5 IAGPM - Governance Air Traffic Control

NIST/ISO/PMI-framed decision rituals and accountability.

1. PRDs & Intent → DomainForge™
   ├── Extract Entities, Resources, Flows, Policies
   ├── Express in SEA™ DSL (versioned .dsl.yaml)
   └── Validate (no dangling references, policy conflicts)

2. DomainForge™ → SEA™
   ├── Semantic Core ingests as canonical meaning space
   ├── KGS mirrors into knowledge graph
   └── CALM defines architecture policies

3. DomainForge/SEA™ → VibesPro™
   ├── Project to port-spec (bounded contexts, aggregates, ports)
   └── Generate domain, adapters, persistence, APIs, tests, CI

4. VibesPro™ → SEA™ Runtime
   ├── Deploy into observable environment
   ├── Link to KGS & models for reasoning
   └── Govern via CALM + IFL + Identity Tokens

5. SEA™ Runtime → Feedback → DomainForge™
   ├── Gather usage patterns, failures
   ├── Propose model updates (human + agent)
   ├── Re-validate and regenerate
   └── Log to IFL, track with Identity Tokens

Result: Closed-loop self-architecting system

5. Developer Workflow

5.1 Change Flow

Change PRD → Update DomainForge™ Model → Re-run VibesPro™ Generators → All Projections Stay In Sync

# Generate port spec from model

# Run full CI pipeline

6. CI/CD Pipeline

6.1 Semantic CI/CD Stages

6.2 Self-Healing Mechanisms

6.3 Semantic Drift Prevention

7. Bounded Context Scaling

7.1 Model-Level Contexts

boundedContext: semantic-core
boundedContext: compliance
boundedContext: user-experience

7.2 Scaling Strategy

• Add contexts by defining DomainForge™ segments
• Wire via ports, not direct imports
• Teams own contexts independently
• Separate libraries/apps per context
• Explicit integration ports between contexts

8. Key Invariants

1. Semantic Singularity: There is exactly one canonical definition of meaning (the Model).
2. Isomorphism: All downstream artifacts (code, docs, infra) are projections of the Model.
3. No Exceptions: Business meaning cannot exist outside the SEA-governed model.
4. Regenerability: Code can be deleted and regenerated from the model at any time.
5. Hexagonal Enforcement: Domain layers never depend on infrastructure.
