Durable Agent Authority — for agents that sleep, retry and resume

Durable-execution frameworks make an agent's work survive sleeps, retries, crashes and restarts. KYE Protocol™ makes sure its authority does not silently survive with it. A workflow resumed after thirty days may resume with an expired delegation, a revoked scope, a changed policy version, or a human approval that covered the start of the run but not its continuation. Durability of execution is not durability of authority.

Durable Agent Authority, step by step

Demo data

You learn: What happens at each step. You can: Step through it.

  1. Step 1 of 6

    KYE Protocol™

    Resume after sleep

    the delegation that authorised step one may have expired before step nine wakes up.

  2. Step 2 of 6

    KYE Protocol™

    Retry after failure

    a retried payment or filing is a second consequential action, not a replay of the first.

  3. Step 3 of 6

    KYE Protocol™

    Policy version drift

    the rules changed mid-run; the next action must resolve against the current version, with the change on the record.

  4. Step 4 of 6

    KYE Protocol™

    Approval staleness

    a human sign-off at launch does not cover a continuation weeks later; KYE™ re-checks whether the approval still binds.

  5. Step 5 of 6

    KYE Protocol™

    Revocation mid-run

    when authority is withdrawn, the running workflow must lose its permission at the next boundary, not at the next deploy.

  6. Step 6 of 6

    KYE Protocol™

    Handover between agents

    a continuation picked up by a different worker or sub-agent is a new principal and needs its own delegation chain.

KYE™ is not a durable-execution framework, a workflow engine or an orchestrator. It is the authority layer underneath them: at every resume, retry and continuation, KYE™ re-resolves whether the agent still holds valid authority for its next consequential action, then emits a signed, replayable record. Your durable runtime asks whether the workflow survived; KYE™ asks whether its authority did.

The line: a resumed workflow vs. a re-authorised action

Your durable runtime replays event history and restores state so the agent continues exactly where it stopped. That is the correct behaviour for the work — and the wrong default for the authority behind it. Authority has an expiry, a scope, a policy version and an approver, and all four can change while the workflow sleeps.

Your durable runtime asks

Did the workflow survive the crash, the sleep, the retry — and can it continue deterministically from recorded state?

KYE™ asks

When it continues, does the agent still hold valid authority — unexpired mandate, unrevoked scope, current policy version, fresh-enough approval — for the next consequential action?

A durable agent that resumes is a new authority event, not a continued one. The run identity persists; the permission to act must be earned again at the boundary. KYE™ answers with allow / deny / require_approval / suspend, and every verdict seals a KYE™ Evidence Pack™ that an auditor can replay long after the run has finished.

Every one of these is a new authority moment

Long-running agents cross authority boundaries that short-lived ones never see. KYE™ gates each of them at the moment it occurs — not once at launch.

  • Resume after sleep — the delegation that authorised step one may have expired before step nine wakes up.
  • Retry after failure — a retried payment or filing is a second consequential action, not a replay of the first.
  • Policy version drift — the rules changed mid-run; the next action must resolve against the current version, with the change on the record.
  • Approval staleness — a human sign-off at launch does not cover a continuation weeks later; KYE™ re-checks whether the approval still binds.
  • Revocation mid-run — when authority is withdrawn, the running workflow must lose its permission at the next boundary, not at the next deploy.
  • Handover between agents — a continuation picked up by a different worker or sub-agent is a new principal and needs its own delegation chain.

This is continuous authority resolution: the mandate is checked at every consequential step for the life of the run, and each verdict is signed, tenant-scoped and replayable.

For teams building on durable-execution frameworks

If your agents run on Temporal-style durable workflows — resumable state machines, event-sourced steps, human-in-the-loop pauses — KYE™ is the authority layer beneath the framework. The framework owns progress; KYE™ owns permission. This division is deliberate: KYE™ never runs, schedules or orchestrates the workflow (§0.30 boundary) — it decides whether each step's consequence may become final.

The integration is a runtime check at the step boundary: before a consequential step executes — on first run or on resume — the agent asks KYE™ for a verdict. KYE™ evaluates actor, delegation chain, purpose, data scope, policy version, approval freshness and finality state, returns the decision, and seals the evidence. Your workflow code stays deterministic; the authority state lives outside it, where it belongs — an approval baked into workflow history at launch cannot express an authority that changed while the run slept.

One authority spine under every durable agent

Durable-agent governance reuses the same runtime primitives that govern every other KYE™ action — one control point, whether the agent lives for a second or a quarter. Nothing here is a separate durable-agent system.

Authority Gateway™

Runtime allow / deny / require approval / suspend at every step boundary, including resume.

Purpose Permission™

Binds each step to a permitted purpose and data scope — re-checked on continuation.

Decision Map™

Inputs, policy version, model, human override and verdict for each step's decision.

Evidence Pack™

Signed proof of actor, mandate, approval freshness and finality — one per verdict, for the life of the run.

Replay-Proof™

Offline reconstruction of why any step was allowed or blocked, from public keys alone — months after the run ended.

Entity & Principal Registry

Every durable worker, sub-agent and continuation is a governed principal with its own delegation chain.

The result is one provable answer for every step of a long-lived run: who held authority at that moment, for what purpose, under which policy version, with what evidence — and whether the step became final under Authority Finality™.
