The agent runtime · in active development

Governed work on real applications.

When an agent has to operate the system, not just answer questions about it. The runtime, in active development, is built to carry the audit substrate into the action: every operation attributed, every refusal recorded, every handoff governed, inside your boundary, on the systems your team actually uses.

§ 01 Why a runtime

When the agent is the actor.

Most agent work today is text in, text out. The agent receives a prompt, produces a response, and the application around it decides what happens next. That model fits a class of work. It does not fit the work where the agent has to operate a real application, navigate a real desktop, take a real action against a real system.

The risk, audit, and compliance functions care about what the agent did, not what it said. When the agent is the actor, the substrate has to govern the action where it happens, not the prompt that produced it.

The runtime is the layer where governed agents operate real systems. The audit substrate carries through: every operation against the application is itself an attributed audit event.

§ 02 What it does

Governed agents. Real systems. The audit substrate, end to end.

The runtime extends the substrate from the agent's decisions to the agent's operations, with the same record and the same attribution at every step.

Real application operation

The agent drives an actual application: a browser, a desktop application, a system console, the same surfaces a human operator uses. The substrate records the operation: which agent, which application, which action, against which target.

Policy at the operation boundary

Every operation the agent attempts is evaluated against the policy in force at the moment of operation. The policy can refuse the operation, and the refusal is itself a recorded action.

Multi-application handoff

When the work spans multiple applications, the runtime carries the audit context across the handoff. The receiving application sees the prior action as attributable history, not as opaque context.

Desktop-context awareness

The runtime understands the surface the agent is operating, and the audit chain records the operation against the actual element, the actual data, the actual outcome. The auditor sees what happened, not a paraphrase of it.

§ 03 What it enables

Operations on real systems

Audit-relevant operations agents have to perform on real systems, where the prompt-to-completion model leaves the action ungoverned and the audit incomplete.

Multi-application workflows

Work under governed discipline where the audit chain has to follow the work across the seams between systems, not stop at the boundary of each one.

Human-equivalent operator surfaces

The agent's actions go through the same systems your operators use, and the audit chain answers the same question for either kind of actor.

§ 04 How it fits

The same substrate, extended to the action.

The runtime runs on the same substrate the rest of the product runs on. The policy is the same code, reviewed the same way, enforced the same way. The audit chain is the same hash-chained record, retained the same way, verified the same way.

The deployment posture follows the same pattern: the substrate runs inside your perimeter, air-gap-capable. The runtime ships in the same containers, runs against the same policies, retains the same audit chain. The models behind the agents are the public APIs your team already uses; running them inside your boundary is the path the model-training pipeline opens.

The runtime engagement starts in the Discovery cycle, the same way every other capability does. Discovery names which workloads in your environment benefit from the runtime, what they look like in production, and what the audit posture has to be.
