Machine Intelligence can be useful architecture language because it is more engineering-oriented than AI, reduces anthropomorphic framing, and points to managed machine behavior rather than speculative cognition. AI remains the common public term; MI is useful when precision about controls, telemetry, and runtime boundaries matters.
Definition and scope
A Machine Intelligence Runtime is an enterprise execution-time control layer that coordinates model-backed work across identity, policy, memory, tools, model routing, evaluation, telemetry, audit, budgets, and governed state changes. It separates probabilistic generation from deterministic authority so machine intelligence can operate inside business, security, compliance, and cost boundaries.
Runtime boundary
| Question | Boundary answer |
|---|---|
| Receives | Authenticated business intent, policy context, model-backed task requests, evidence references, tool contracts, budget constraints, and approval signals. |
| Owns | Runtime orchestration, policy, memory/context minimization, tool brokering, model routing, telemetry, audit evidence, cost controls, and governed state changes. |
| Emits | Governed action results, decision records, audit trails, model-call traces, cost reports, approvals, denials, and reproducibility metadata. |
| Does not own | A single model, one provider’s API, a generic chatbot, or the final business outcome without product-layer ownership. |
Where MIR fits in the seven-layer stack
| Layer | MIR relationship |
|---|---|
| L0 | Infrastructure provides isolation, networking, and storage substrate |
| L1 | May rely on model execution providers but does not own kernels |
| L2 | May consume compiled graphs or policy artifacts |
| L3 | Routes model calls and records model/version evidence |
| L4 | Coordinates serving, distributed execution, and context services |
| L5 | Primary governance of agents, tools, memory, policy, and telemetry |
| L6 | Interfaces with product workflows and business state changes |
MIR reference architecture
| Layer | MIR Responsibility |
|---|---|
| Product/Application | Captures intent, user workflow, domain outcome |
| Runtime Orchestration | Schedules steps, manages deadlines, retries, checkpoints |
| Policy & Permissions | Verifies identity, tenant, delegated authority, approval |
| Memory & Context | Retrieves approved evidence with provenance and minimization |
| Tools & Connectors | Executes typed external actions through brokers |
| Model Adapters | Routes to model/provider/engine with budget and fallback |
| Evidence & Telemetry | Logs decisions, outputs, traces, costs, policy, and outcomes |
Audit logs and 12-field minimum evidence
| Field | Purpose |
|---|---|
| Timestamp UTC | NTP-synced execution time |
| Unique decision ID | Identifier linking runtime event to downstream records |
| Human user identity | Authenticated human directing the workflow |
| AI system identity | Runtime, agent, deployment, and framework version |
| Model and weights version | Pinned model identifier or provider version |
| Inputs and data lineage | Prompt, context references, and source provenance |
| Policy or rule invoked | Control applied at execution time |
| Semantic reasoning or decision explanation | Structured decision summary, not hidden chain-of-thought |
| Output produced | Exact text, code, or structured payload emitted |
| Downstream action | API call, database mutation, email, ticket, or external side effect |
| Human oversight | Approver, escalation, override, or review record |
| Cryptographic proof | Hash chain, signature, or tamper-evidence marker |
This evidence model should be tied to the existing Runtime Contract, Evidence Schema, Trace Schema, Tool Contract, and Policy Approval Contract pages.
Why enterprise AI needs runtime governance
Enterprises cannot govern model-backed work through documents alone. Identity, policy, cost, context, side effects, and audit evidence have to be enforced at execution time.
Machine Intelligence versus Artificial Intelligence terminology
AI remains common. Machine Intelligence is useful when the discussion needs less anthropomorphism and more emphasis on bounded machine behavior, telemetry, and runtime control.
MIR versus agentic runtime versus AI control plane
An agentic runtime controls agent workflows. A control plane manages platform configuration. MIR is the execution-time control layer that binds identity, policy, memory, tools, models, budget, evidence, and governed state changes together.
Application layer and request boundary
The product captures user intent and domain outcome. MIR receives a structured run request and refuses to mutate business state without a governed path.
Runtime orchestration
MIR schedules steps, manages timeouts, retries, checkpoints, cancellation, fallbacks, and dependency ordering.
Policy and permissions
Policy enforcement should bind user identity, tenant, data class, tool contract, approval state, risk level, and execution context.
Memory and context
MIR retrieves only approved context and records provenance. It should avoid indiscriminate prompt stuffing and preserve source references.
Tools and connectors
Tools should be typed, scoped, idempotent where possible, and mediated by brokers that understand side effects.
Model adapters
Adapters normalize model calls, track versions, budgets, fallbacks, streaming, and quality checks.
Evidence and telemetry
Evidence is not an afterthought; it is the substrate for reproducibility, incident response, and audit.
Neuro-symbolic execution and deterministic grounding
Probabilistic generation proposes. Deterministic rules, contracts, policies, schemas, and verifiers decide whether action is allowed.
Token economics and cost governance
MIR should meter cost per workflow, apply quotas, route by task complexity, and use semantic caching where the result can be safely reused.
Service account gap and dual attribution
Downstream logs must preserve both the machine actor and the authenticated human authority behind the workflow.
MCP and tool standardization
MCP can reduce integration sprawl, but MIR still needs authorization, egress control, evidence, and identity binding.
Agent event behavior monitoring
Runtime traces should detect abnormal tool chains, lateral movement, repeated denials, budget exhaustion, and unusual data access.
Zero-trust agent identity
Agents should carry verifiable identity, version, scope, and credential posture instead of relying on prompt claims.
DIDs, VCs, attestation, and runtime credentials
Decentralized identifiers, verifiable credentials, and attestation are candidate mechanisms for cross-boundary agent identity when the ecosystem supports them.
Deployment topologies
MIR may run locally, as a hybrid edge-cloud runtime, as a cloud-managed enterprise runtime, at branch/edge nodes, or as a federated runtime across business units and partners.
Adoption roadmap
Start with gateway observability and tool contracts, add policy and audit evidence, then introduce memory governance, cost controls, evaluation, and dual attribution.
Failure modes
- Unbounded model authority
- Prompt-only compliance
- Missing human attribution
- Budget runaway
- Untraceable tool calls
- Provider lock-in
- Memory contamination
- Policy bypass through connectors
- Non-reproducible decisions
- State mutation without approval
Evidence and metrics
- Task completion
- Policy coverage
- Token/cost per workflow
- Model route distribution
- Cache hit rate
- Tool failure rate
- Audit completeness
- Human approval rate
- Time to resolve incidents
- Reproducibility of decisions
- Data lineage coverage
- Drift and fairness checks where appropriate
Decision checklist
- Define the run contract and evidence schema.
- Bind human identity to machine actions.
- Route tools through brokers.
- Record model and policy versions.
- Meter token and compute cost before deployment.
Common mistakes
- Treating a model API as an enterprise runtime
- Treating prompt policy as compliance
- Treating service-account logs as sufficient attribution
- Forgetting cost controls
- Logging final answers but not tool calls
- Mixing product state, memory, and workflow checkpoints
- Locking the entire architecture to one provider
- Treating AI governance as a document process instead of runtime enforcement
Implementation blueprint
The v3.5.0 continuation adds a deployable implementation lens for this category. Treat the page definition as architecture guidance, then test the concrete boundary through contracts, telemetry, rollback, and review records.
| Level | Required control |
|---|---|
| Minimum viable MIR | Identity-aware request boundary, model routing, approved context retrieval, policy decision, tool authorization, cost metering, evidence record, and deterministic state-change gate. |
| Production MIR | Dual attribution, model/version registry, budget allocation, evaluation hooks, incident replay, cryptographic proof, data-lineage coverage, and approval expiry. |
| Release gate | Do not ship until every downstream action can be traced to user, model, policy, evidence, tool contract, cost, and approval state. |
MIR governed run record
This compact example is not a mandatory schema. It shows the kind of typed boundary record that should exist before the runtime term appears in production documentation.
