# Peer board math demo — transcript

## 00:00 — Four sessions. One peer board.

Four independent Rysh sessions, one leader and three workers, communicating through a shared peer board. Each keeps its own panes, files, and Claude conversation. These real sessions run on one demo host. The same message boundary connects developers on different machines.

## 00:20 — Three ways to solve one problem

The challenge is to cross a six by six grid, moving only right or up, without visiting the center point. The leader delegates three independent approaches, a mathematical proof, dynamic programming, and exhaustive enumeration.

## 00:37 — Ask. Pause. Resume.

The enumeration worker asks a scope question through the peer board. Does avoiding the center mean never visiting the lattice point 3-3? Its agent pauses. The leader replies with the task identifier, and the listener resumes the same local conversation.

## 00:55 — Independent work, shared evidence

The proof counts 924 total paths, subtracts 400 through the center, and gets 524. Dynamic programming reaches the same answer. The third worker enumerates every valid step sequence, and independently confirms the count.

## 01:14 — The leader reviews all three results

A submitted result still needs review. The leader checks the evidence from each worker, accepts all three tasks, and publishes the shared conclusion. 524 paths. The work stayed in three separate local work trees.

## 01:30 — Leadership changes; history stays

Next, a leader endpoint registers inside the proof session. The current leader hands over authority, advancing the board to term 2. The successor reads the existing results, and confirms the answer. Completed tasks and their evidence remain on the board.

## 01:49 — A worker leaves the board

The code worker drains its listener and leaves voluntarily. The board retains its contribution, and marks the registration as left. The other sessions continue. Leaving the peer board does not delete the developer session or panes. The check session has also disconnected. This

## 02:07 — More than 15 real minutes offline

was a real wait of more than 15 minutes, shortened here for the video. Other peers see it as offline. Its identity and completed result remain recorded, and no duplicate task is launched.

## 02:25 — Reconnect with the same identity

The check worker reconnects with its original identity, accepts the new leader, and sends a return message. Four independent sessions have coordinated through messages alone. This is a condensed replay of their recorded events. The original terminal captures are included. The narration is AI-generated.
