Bundle static Linux wr-agents in Release and Nightly builds - #233
Conversation
…ilds Phase 3 of #154 pushes the agent to a remote box on first connect, which depends on Workroom.app carrying a Linux agent. build-agent.sh now cross-builds wr-agent for aarch64 and x86_64 musl with cargo-zigbuild and the terminal-state feature, and puts them at Contents/Resources/wr-agent-linux-<arch>, unsigned, sealed by the app's own signature. Both arches ship regardless of ARCHS. Debug builds skip them and remove stale ones unless WR_AGENT_LINUX=1. release.sh fails a release whose ELFs are missing or not static, the new agent-linux CI job runs `protocol` on each under Linux, and the release workflows install the musl targets and cargo-zigbuild. Whether notarization accepts the ELFs is answered by the first Nightly built with them. Part of #227. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

…uilds Only the Mac agent can be run on the build host, and the build test asserts terminal-state on it. Building the Linux ELFs from the same feature list extends that check to them, so dropping terminal-state from the Linux build alone is no longer possible. Found by Greptile on #233.

Part of #227 (Phase 3 of #154, first milestone). It does not close #227: that issue's notarization criterion can only be confirmed by a real Nightly, which runs after merge.
What changes
Phase 3 pushes the agent to a remote box on first connect, so Workroom.app has to carry a Linux agent. The design doc's Distribution Plan names one thing to confirm before that is load-bearing: does codesign and notarization accept a Linux ELF sealed as a resource inside a notarized
.app? This PR ships the ELFs so the next Nightly answers it.build-agent.shcross-buildswr-agentforaarch64-unknown-linux-muslandx86_64-unknown-linux-muslwith cargo-zigbuild and theterminal-statefeature, and copies them toContents/Resources/wr-agent-linux-{aarch64,x86_64}, named by whatuname -mprints on the far side.ARCHS.WR_AGENT_LINUX=1(owner's decision, somake app-buildstays fast).cargofrom PATH and a Homebrew cargo there cannot build for musl (the traptest-linux.shdocuments).release.shfails a release whose Linux ELFs are missing, not static, or the wrong arch.agent-linuxjob builds each target on ubuntu and runswr-agent protocolon it (aarch64 under qemu-user-static), requiringterminal-state yes. Theappjob now installs the musl targets and cargo-zigbuild, sobuild-agent_test.sh's Linux cases run on every PR rather than skipping silently. Without that, the script's Linux branch would first run on a Nightly, which is the same gap the darwin cross targets once had.macapp/AGENTS.md(Linux agents), and the design doc (Current Status corrected: Phase 2 is merged and Phase 3's sub-issues are Linux wr-agent as a published build artifact #227–Stop-and-reboot screen restoration #232; the Distribution Plan's ELF question is marked in progress, with sizes).Cost
10.9 MB (aarch64) plus 12.3 MB (x86_64) in the installed app, and about 11 MB in the DMG. A cold cross-build is about 2 minutes per arch locally.
