Several agents want to ship, and production has one slot. Intramedial queues them as leases, rolls each change through stages with a check between them, and refuses a write that did not take its turn.
coordination.admit change-trains.list previews.list mcp.enforce Put admission in front of your MCP servers, repositories, SaaS tools and cloud accounts. Every agent gets a lease or a reason – and you keep the lever to stop any of them.

Report abuseA pipeline can serialise jobs it knows about. It cannot serialise agents that decide for themselves when to ship, and it cannot show who skipped the line.
Who is shipping to production right now, and who is next?
Did that change go out in stages, or all at once?
Can we show which agent pushed to the main branch?
A lease on the slot answers the first, a change train the second, and the repository gate the third. Each is only as complete as the traffic routed through it.
AppliesPhased from 2026
Makers of products with digital elements must handle vulnerabilities and keep their development process controlled. A queued, staged and recorded release is part of showing that control.

A release that arrives in stages with a check between them can be stopped halfway. Customers and insurers ask whether yours can.
Legal references are summarised and dated as of October 2026. They are given so you can see where the need comes from, not as legal advice. Read the official text, and ask counsel how it applies to you. Intramedial does not make any organisation compliant with any law.
The release agent requests an exclusive lease. If another agent holds it, the request waits in the queue and the holder is named.
Policy, pack or role changes move through stages with a measured check between them. A failed check sends the change back.
The GitHub write gate and the MCP gateway admit each write against the leases in force for that repository or tool.
Each lease, stage and write is in the ledger, and every preview arena is removed when its pull request closes.
Each module decides one kind of thing. Open a module for its fields, limits and errors.

A ledger entry is evidence of a narrow fact: this decision was made on this input under this policy at this time, and the chain has not changed since. It is not a certificate, an audit or legal advice, and it does not by itself satisfy any legal obligation.
Stop two agents from writing to the same repository, table or slot at once, and show which one held it and why the other waited.
