Conversation
The article-of-record audience runs orchestrators on VPSes and homelabs; Threadlines could already serve them headless but had no packaged way to do it. docker/Dockerfile builds a service appliance from the published npm package: Claude Code and Codex CLIs baked in, tini for agent process trees, non-root user, home volume for data and provider credentials, /workspace for repos, healthcheck, and auto-bootstrap disabled (a service must not mint a project from its own working directory). docker/README.md is the two-command operator guide. Two fixes fell out of the cold-user verification: - THREADLINES_ADVERTISED_HOST: startup URLs advertised the container's internal address, which no client can reach. An operator-set host now wins over interface resolution. - effect PubSub patch: every abrupt websocket disconnect logged "Failed to publish disconnected-session auth update" with a TypeError from inside effect's PubSub - an interrupted poller leaves an undefined hole in the pollers list and the publish path dereferences it. The patch skips holes. Reproduced deterministically (pair, open app, kill the browser context), clean after; upstream report worth filing.

Threadlines could already serve them headless but had no packaged way to
do it. docker/Dockerfile builds a service appliance from the published
npm package: Claude Code and Codex CLIs baked in, tini for agent process
trees, non-root user, home volume for data and provider credentials,
/workspace for repos, healthcheck, and auto-bootstrap disabled (a
service must not mint a project from its own working directory).
docker/README.md is the two-command operator guide.
