The last entry ended with AIs that could finally talk to each other. The first week of April fixed a quieter problem: they couldn't reliably *remember together*.

## Five photocopies of one notebook

Every Claude Code window that used Knowledge Network started its own private copy of the graph. Picture five people each given a photocopy of the same notebook. Each writes in their own copy and nobody sees the others' notes. At the end of the day, whoever files last overwrites everyone else.

That's what was happening. Sessions read each other's work late or not at all, and a save could silently undo another session's. Each copy also loaded the whole graph into memory on its own.



On 3 April the copies were replaced by one background service that holds the graph once. Every session plugs into it, so a note written in one window is there in the next, straight away. The first hiccup was very on-theme: for a while two copies of the shared service started at once and fought over the same connection.

## One graph, arranged as a tree

Two days earlier the last separate graph had been folded in, with the founder's personal research joining the project's own knowledge. Efforts got parents and children, so the work began to look like a tree of projects instead of a flat list. Search across everything had been working since the end of March.

## Two devices, one memory

On 4 April the graph learned to sync between machines. Two computers on the same network find each other automatically. When one changes, it says so, and the other asks only for what it's missing. Machines elsewhere can be dialled directly. In the test, a claim added on one machine showed up on the other within seconds, and the two copies matched exactly. This is where the CRDT storage from the Rust rewrite paid off.

## Who wrote this?

On 5 April every claim, effort and preference started recording *which session* created it. The shared service works this out by itself, by looking up which Claude Code window is on the other end of the connection. The same day uncovered a related bug: two sessions could clobber each other's idea of what they were working on, because "the current effort" was a single global setting. It became a per-session one.

Tagging work by session sounds like bookkeeping. It's the first step toward a principle the project later made a rule: anything one AI changes that another could stumble on must be traceable to the work that caused it.

## Open questions

- One shared service means one place where everything can go wrong at once. How do you keep it honest when many AIs lean on it all day? The rest of April worked on exactly that: locks, inboxes and journals.
