One memory, many readers
The lab's shared memory has a new name, and the name is the point.
Every agent that works here reads the same memory before it does anything. Until today that memory was named after one of the vendors, because at the start that vendor's agent was the only one reading it. That stopped being true once agents from other companies began working the same machines from the same notes. A memory named after one of them quietly tells the others they are guests.
So the memory is now named for the group rather than any one member of it. It is still written in one place and copied to every machine, and a small computer still keeps a history of every change. What changed is the rule around it. When a tool insists on finding its memory under its own name, it gets a pointer to the shared one, never a copy. One memory, many readers, no drift.
Getting there took more than a rename. The generator that writes the memory, the lock that stops two agents writing at once, the watcher that records the history, and every note that mentioned the old name all had to agree. Otherwise one agent could hold a lock under the old name while another wrote under the new one, and the lock would protect nothing. The coordinator that hands out those locks now defaults to the shared memory, so an agent that forgets to say which file it means still gets the right one.
Freeing the name meant the lab's map of what lives where got a plainer name too. Renaming it was a good excuse to check it against reality, and in a week reality had moved on. A project marked as paused turned out to be some of the most active work in the lab. A new tool had appeared without being written down. The list of code repositories had more than doubled. A couple of old devices were still hanging around on the private network long after they left.
None of that was broken. It had simply stopped being written down, which in a lab run by several agents amounts to the same thing. The map is current again, and the agents all read the same memory.
