问题描述 · Description

Sessions started via the SSH remote feature are only visible on the machine that initiated them, never on the machine that actually runs them.

My setup: a workhorse MacBook at home (always plugged in, running ZCode) and a travel MacBook. From the travel MacBook I start ZCode sessions on the workhorse over SSH. Those sessions appear only in the session list of the travel MacBook. On the workhorse itself — the machine executing the session — the session does not appear anywhere: not in the session list, not in the group/paired-devices view.

So when I am physically at the workhorse, I cannot open, monitor, or continue a session that the machine is already running. The session is invisible exactly on the machine doing the work.

Workarounds already tried, per suggestions in the Discord support thread:

• "group" view → the remote-started session does not appear there.
• Pairing with Telegram → works, but not a good option for coding work.

复现步骤 · Steps to reproduce

1. On MacBook B ("workhorse"), have ZCode running and signed in.
2. From MacBook A, start a ZCode session on MacBook B via the SSH remote feature.
3. Let the session run (agent actively processing on B).
4. Sit down at MacBook B and open the ZCode session list, then the group view.
5. The remote-started session is listed on neither — it exists only in the session list on MacBook A.

期望表现 · Expected behavior

A session running on MacBook B should also be visible and openable on MacBook B itself, so I can check its progress and continue it locally when I'm at that machine.

实际表现 · Actual behavior

The session is only visible in the session list of the initiating machine (A). Machine B, which is actually executing the session, shows nothing — no entry in the session list, none in the group view.

Screen recordings of the repro are available and can be attached on request; debug logs can be provided too if useful.

Context: discussed in the official ZCode Discord support thread ("Any way to locally check a session that was started remotely?"); staff suggested escalating here.

Start by reproducing the SSH remote session flow between two Apple Silicon Macs, then inspect the session list and group/paired-devices view on the executing Mac. Use the reported zcode-app-cli 3.11.2-25 and zcode-runtime 0.16.5 versions, with debug logs if needed. Done means a session started remotely on Mac B is visible, openable, and continuable there.
