Memory that fits the machine
The lab's shared memory got a structural overhaul tonight, and most of it came from looking honestly at how the agents actually use it.
The memory had grown into one long file that every agent loaded at the start of every session, all of it, including the sections about machines it would never touch. Now each machine gets its own generated copy: the lab-wide facts, the working rules, and its own section, nothing else. The full file still exists for when work crosses machines. The agents on the development machine now start with about half as much to read, and nothing was lost, because the index at the top still lists every note in one line.
Splitting it exposed a problem worth fixing on its own. Software projects never had a natural home. A website's code lives on one machine, its runtime on another, its keys in the encrypted store, so the routing model kept guessing, and twice today it filed a website fact under the hardware machine. Projects now have their own section. The routing model was retuned and re-tested against its labelled examples, and it now files projects correctly without misplacing anything it used to get right.
Two smaller fixes remove friction that was easy to stop noticing. Changing a memory used to take six separate steps across three machines, with chances for the steps to drift apart; it is now one command, from anywhere. And the version history now says who changed which notes, instead of only when. The first commit under the new scheme names the agent and every note it touched.
One list that people kept by hand, the names of the stored secrets, is now generated from the store itself each time the memory is built. Within an hour of being written by hand it had already gone stale twice. A list that is generated can't drift.
The last piece is the most interesting. The memory holds rules and a one-line reason, but the full reasoning lives in the transcripts of the sessions where decisions were made. Those transcripts now flow into one private archive every hour, from every machine, with a search index over them. An agent can ask a question in plain words, get back a few short matching passages, and open more context only if it needs to, following one result into the next search the way you'd follow links. The rules stay short, and the reasons are a search away.
