* core: test that history posted before channel signing reaches later joiners as signature missing, and channel moderator delete for all Confirms the case the owner's new alert describes: a subscriber who joins after the owner turned on "Sign messages" sees the earlier posts as "signature missing" and later ones as signed, while earlier subscribers keep them unmarked. Also covers a non-owner channel moderator deleting a contributor's signed post for everyone. Run: 001-channel-signing-moderators, slice 1 * ios: keep "Chat with admins" off when saving group preferences toGroupPreferences left out the support preference, so the saved profile had none and core filled in its default, on: every channel preference save from iOS silently turned on chats with admins, which have no end-to-end encryption in channels. Android and desktop already pass it. Run: 001-channel-signing-moderators, slice 2 * ui: let channel owners turn on "Sign messages", warning that earlier messages will show signature missing The channel preference was hidden while signing was recipient-only. Owners now see the switch; turning it on asks for confirmation, because subscribers who join later receive the earlier posts unsigned through history and see them as "signature missing". The "Signature missing" explanation now says the message may predate signing or have been forwarded by a relay without its signature, instead of only implying tampering. Run: 001-channel-signing-moderators, slice 3 * ui: channel owners can make subscribers moderators, and moderators see the subscriber list Core already lets a channel owner make a subscriber a moderator; the role picker offered only subscriber and contributor. It now offers moderator too (not admin, by decision). Moderators see the full member list the owner sees, so they can reach the subscribers they may block (subscribers can't post, so there was no other way to reach them), and member info is headed Moderator or Contributor instead of Subscriber for those roles. Run: 001-channel-signing-moderators, slice 4 * ci: long-press and right-click for app tests, safer ui arguments, desktop Kotlin 4 GB, desktop session limits from claude-scope Message menus open only on long-press (iOS) or right-click (desktop), so Claude sessions couldn't reach Moderate, Info or Delete. Ported from f/directory-search unchanged, with its hardening: the guards refuse unquoted glob, brace and tilde expansion, and desktop ui checks numbers and sends one key per call so a key argument can't run an xdotool command. The desktop app job's Kotlin compiler gets 4 GB, as f/directory-search needed after merging master. Desktop sessions take max-turns and max-budget-usd from claude-scope like iOS (60 and 3 when unset, as before), and the Claude job may run 120 minutes. Run: 001-channel-signing-moderators, slice 5 * ci: Claude test plans for channel message signing and channel moderators This branch's iOS device test plan and desktop prompt replace master's smoke tests: the owner creates a channel on the preset relays, turns on Sign messages through its alert, and two more profiles in the same app join by the copied link; the owner makes one a moderator, who then sees the subscriber list, moderates a contributor's message and blocks the contributor. Signatures are checked as text in message Info. One layout, no test backend. Run: 001-channel-signing-moderators, slice 6 * fixup! ui: let channel owners turn on "Sign messages", warning that earlier messages will show signature missing * update plans * fixup! ui: let channel owners turn on "Sign messages", warning that earlier messages will show signature missing * fixup! ci: Claude test plans for channel message signing and channel moderators * fixup! ui: let channel owners turn on "Sign messages", warning that earlier messages will show signature missing * fixup! ci: Claude test plans for channel message signing and channel moderators * fixup! ui: let channel owners turn on "Sign messages", warning that earlier messages will show signature missing * fixup! ci: Claude test plans for channel message signing and channel moderators --------- Co-authored-by: spacedandy-agents-simplex <342056592+spacedandy-agents-simplex@users.noreply.github.com>
Desktop app CI on Linux
.github/workflows/desktop-linux.yml builds the desktop app from the branch on a GitHub runner (Ubuntu 24.04), runs its JVM tests (:common:desktopTest), and drives the app on a virtual display: onboarding to the chat list, then the chat list with the toolbar at the bottom (the default) and at the top. On request it also runs Claude Code driving the same path, a test backend, and the latest release as a baseline.
Running it
The workflow runs only when started by hand, on any branch, from the Actions tab or with gh workflow run: CI on GitHub's runners says how and lists the inputs.
Every run builds the core library, and the backend when it's asked for, from the branch's own Haskell code. It reuses an earlier build only when the sources are unchanged, as an artifact of the same branch named after a hash of its sources (30 days): for the core src/**, cabal.project, simplex-chat.cabal, PRIVACY.md and the build scripts, for the backend src/**, the CLI's and the directory's sources, cabal.project, simplex-chat.cabal and its build script. So a branch that changes core and app code together tests both. The workflow saves no Actions caches, which this repository evicts within hours and shares with build.yml.

Queueing for a runner adds from under a minute to 20 minutes. Results are artifacts: desktop-smoke-test (numbered screenshots, the text OCR read from each, steps.log, checks.txt, app.log), desktop-test-report, desktop-claude-test, and the backend's logs; desktop-app, the distributable for manual tests and the Claude job, is kept 14 days. The job summaries list the checks, the desktopTest results and the Claude usage.
Scripts
ui: the UI driver. Compose for Desktop has no accessibility tree on Linux, so it finds text on screenshots by OCR (tesseract) and acts with xdotool on an Xvfb display.uialone prints its commands: start (with app settings), shot, text, find, wait, click, right-click, click-text, scroll, type, key, avatar (a profile image's colour), ink (a text's height), do (several in a row), stop.screen-text.py,screen-colour.pyandscreen-ink.pyare its helpers.smoke-test.sh <app dir> <out dir> [start|onboarding|setup|backend]: the scripted cases; the default is onboarding and both layouts.setupalso creates a local group and makes the test SMP server the app's only names server;backenddoes that, connects to the seeded name, and checks both layouts.backend.sh start <tar.gz> <dir>/stop <dir>: the test backend, below.claude-test.sh,claude-test.md(the prompt),claude-scope(whether the prompt uses the test backend, and optionally the session's turns and budget),claude-guard.py,claude-usage.py: the Claude job.build-core.sh,install-core.sh,build-backend.sh,earlier-run.sh,release-app.sh,test-summary.py: builds, reuse and reports.
The test backend
backend.sh starts, on the runner, with CLI peers:
- a chat relay (
--relay --headless) and a directory service on the preset servers; - a group
ci_groupand a channelci_channelwith letter avatars as large as the apps make them (avatar), registered and approved by the adminci_admin, and found by a new user who sends the directory "ci seed"; - an SMP server on 127.0.0.1:5223 whose
[NAMES]section asksnames-resolver.py, and a contactci_contactwhose address it resolves asseeded.testing, checked with a connect plan from another client.
It writes the directory's address to <dir>/directory-link and the SMP server's to <dir>/names-server. The app reaches the names server only with private routing set to unknown servers (ui start … NetworkSMPProxyMode=Unknown), since the preset proxies can't reach 127.0.0.1, and with the test server's receiving role off: a directory can't answer requests whose reply queue is on it.
The Claude job
It needs the GitHub environment app-sim-claude with the secret CLAUDE_CODE_OAUTH_TOKEN, a Claude subscription token. Which branches may use it is decided only by that environment's branch rule in the repository settings: on a branch the rule doesn't allow, a requested Claude run fails at the environment check. It runs once the app job has passed, on that job's distributable, one per branch at a time. The token goes only to the step that runs claude; claude-test.sh passes it to the claude process alone, and every ui call unsets it too. The job starts the test backend when claude-scope says backend: yes; a run that asks for Claude must then ask for the backend too, or the plan job fails. On master it says no, since this prompt doesn't use the backend. The job installs Claude Code at the version the iOS workflow pins too, and runs claude-haiku-5-5 with the turns and budget claude-scope sets (--max-turns 60 and --max-budget-usd 3 unless it sets max-turns: or max-budget-usd:) and the iOS sessions' other flags (--restricted, --permission-prompts none, --effort high); the job's time limit is 120 minutes. Its Bash runs only single ui commands (claude-guard.py, a PreToolUse hook: Claude Code runs read-only commands without asking in every permission mode). Before anything the session wrote is printed or uploaded, claude-test.sh checks it for the token; if it's there, the output, transcript, Claude Code's stderr and the guard log are deleted and the job fails. It passes when Claude's final message ends with CLAUDE-TEST: PASS; report.md, the transcript, the guard's log and claude-usage.json are in desktop-claude-test.
Cost
The runners are free for this public repository. A Claude run spends the subscription's usage limits, which interactive sessions share: Haiku 5.5 does this smoke path in 15 to 30 turns, 0.01 to 0.02 USD estimated at API prices (Claude Code's estimate, not a bill on a subscription).
