§ Platform / Agent Governance

Agents act. The runtime decides what they're allowed to do.

Autonomy without governance is liability at machine speed. Summit's agent runtime is deny-by-default: every tool call is policy-checked before it executes, every sensitive action requires structured approval, and every run can be replayed exactly — including air-gapped.

§ 01

Default deny, at the tool boundary

The tool boundary is where agent intent becomes real-world effect — so that is where governance lives. No tool call executes until policy admits it.

  • Gated tool access. Every tool invocation — file writes, network calls, deployments, external APIs — passes through a policy gateway. The default verdict is DENY; capability must be granted, scoped, and recorded.
  • Rule of Two. Sensitive actions require a second, independent approval before execution — a structured check, not a rubber stamp, with both verdicts captured in the evidence chain.
  • Every denial is evidence. Blocked calls are not silent failures. Each verdict — admit or deny — lands in the audit record with the rule that produced it.

§ 02

Memory you can defend

Agent memory is an attack surface. Whatever an agent reads can steer what it does next — so material earns influence through explicit trust states, and roles stay isolated.

Memory

Explicit trust states

Material moves through a declared ladder — raw, proposed, validated, approved — and policy decides what each state is permitted to influence. Untrusted content cannot silently become operating instructions.
Memory

Poisoning resistance

Because influence is gated by trust state, injected or manipulated content stalls at raw — visible, quarantined, and inert until a validation step it cannot fake.
Fleet

Role isolation

Agents operate in separated roles with distinct capabilities and memory boundaries. A compromised researcher cannot act as a deployer; the blast radius is structural.
§ 03

Replayable runs, gated releases

Governance that cannot be demonstrated after the fact is just configuration. Every agent run is reconstructable, and nothing ships without passing its gates.

Prove

Deterministic replay

Recorded inputs, policy versions, and tool verdicts make any run reproducible — bit-identical, on demand, including in air-gapped environments where the original infrastructure is unreachable.
Ship

Release gates

Agent-produced changes pass through evidence-backed gates before release: policy evaluation, approval records, and verification results — assembled into a package your review board can actually review.

Govern one fleet. Prove it worked.

The 10-day pilot puts a real agent workflow under the runtime — gated tools, trust-stated memory, full replay — and finishes with findings in writing.
