What is CueCrux and what problem does it solve?

CueCrux is the governance control plane for AI agent fleets. Agents now act thousands of times a day: reading, writing, spending, calling tools. Almost no organisation can produce a verifiable record of what its agents actually did, what each action cost, or that a revoked permission is really gone.

CueCrux answers those three questions with machinery rather than dashboards:

• Cost attribution. Spend traces from fleet to agent to verb to receipt. Nothing is estimated.
• Receipts as debugging. Every state mutation is signed into a hash-chained trail you can replay, offline, without trusting our servers.
• Revocation that propagates. A signed pull, per-agent acknowledgements, and an attestation when zero holders remain.

It starts as one free binary, the Crux Daemon, running locally with no account. The fleet products are the same machinery at organisational scale.
