From d961f7de0ce466ddadac13de41bb89b5a9d39b1a Mon Sep 17 00:00:00 2001 From: Vladimir 'join3r' Schmotzer Date: Tue, 13 Oct 2026 23:48:56 +0200 Subject: [PATCH 01/47] Chats can be archived, not just deleted MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Right-click → Archive (or ⌘⇧A on the open chat, or the selection bar for several) moves a chat out of the tree into a folded "Archived (N)" section at its foot. Nothing is lost: it opens, searches (with an archive badge) and comes back with "Move out of archive", or on its own with the next turn. The delete confirmation now offers "Archive instead". Same server store and placement rule the iOS chat list already used, so both clients agree on what is archived.

From ae0788a7eca56873c51f1de5a9ff74c54a7d3d17 Mon Sep 17 00:00:00 2001 From: Vladimir 'join3r' Schmotzer Date: Wed, 14 Oct 2026 01:18:32 +0200 Subject: [PATCH 04/47] Browser control on Linux: start only browsers Stem knows On Linux the browser id is an executable that Stem runs to start the browser, and it arrives from the native host's hello. A peer with the token could name any program. Stem now starts, or hands the extensions page to, only known browser binaries in system folders (Chrome, Brave, Edge, Chromium) or the known launcher commands; anything else gets "open it yourself". Verified the Linux paths with the real extension in Debian's Chromium 155: the host manifest in ~/.config/chromium/NativeMessagingHosts is found, and the host's parent reads as /usr/lib/chromium/chromium.

It passes on macOS (Chrome for Testing) and in the container (Debian chromium), and fails on Linux with the old Mac-only gate put back. CI installs Chromium so both jobs run it. Set up opens nothing under STEM_E2E, and the Load-unpacked spec now runs on Linux too. The Arc sidebar test lost a dead 2 s wait that made it flake under a loaded full run.
