ci(release): build, sign, and publish self-contained CLI archives

[juliusmarminge]

Part 3 of 8 (stack #11411). Builds on #11316.

What ships

The desktop build runners for macOS arm64, Linux x64, and Windows x64 now also produce t3-<version>-<platform>-<arch>.tar.gz (.zip on Windows) containing the single-executable server, the web client (sourcemaps dropped), the resource monitor, and a hoisted production install of the runtime-external native packages with foreign node-pty prebuilds pruned. Unpacking it needs neither Node, npm, nor a compiler. The release job attaches the archives with a SHA256SUMS written from the signed bytes.

• scripts/build-cli-archive.ts stages and packs the archive. macOS: Developer ID signature with hardened runtime on the executable and on every .node/spawn-helper/resource-monitor binary, then notarization when the Apple secrets are present (ad hoc otherwise, which still runs from curl/tar installs). Windows: Azure Trusted Signing through the same Invoke-TrustedSigning setup the installer uses, after zeroing the stale Authenticode data-directory entry that node --build-sea leaves in the PE header (Trusted Signing refuses the file otherwise with 0x800700C1, and signtool remove cannot strip it). Same rule on every channel, including nightly.
• scripts/smoke-cli-archive.ts extracts each archive on its build runner with a clean environment and runs --version plus the service preflight (which loads sqlite, node-pty, and msgpackr-extract) before the artifact is uploaded. On Windows it extracts with System32\tar.exe (bsdtar) because Git Bash's GNU tar cannot read zips.
• Each archive is built on its native runner with the host's Node injected by --build-sea. VP_NODE_VERSION is pinned to the exact 26.8.2 in the workflow (the setup action 404s on a bare major). The macOS x64 archive is disabled for now: cross-injecting into the x64 Node on the arm64 runner produced a binary that segfaults under Rosetta, and there is no x64 runner to verify on.

Temporary preview channel

workflow_dispatch gains channel=preview, a dogfooding train for the archive-based runtime that never reaches nightly or stable users. It uses nightly's date-and-run versioning under the preview prerelease identifier (0.0.41-preview.<date>.<run>) and publishes only a GitHub prerelease; the hosted web app, AUR, and Discord steps are skipped. Preview versions are branded as nightly. Remove once archives are the default.

A preview build is obtainable only by downloading it from its release, and the workflow enforces that at every layer that could otherwise surface it to a real user:

• it is not published to npm, so no dist-tag can resolve to a preview version;
• preview desktop builds are packaged without a publish config (same path as -pr. builds), so they ship no app-update.yml and electron-builder emits no latest*.yml/nightly*.yml manifests or blockmaps for them;
• the release job lists updater files only for stable and nightly, and fails the run if any manifest shows up in a preview's assets.

The first preview run (v0.0.41-preview.20260912.1589) predated this: it attached latest*.yml manifests and published t3@preview. That release and its git tag have been removed; the t3@preview dist-tag and 0.0.41-preview.20260912.1589 version still exist on npm and need removing by an npm owner (npm dist-tag rm t3 preview, npm unpublish t3@0.0.41-preview.20260912.1589).

Verification

• resolve-nightly-release, resolve-previous-release-tag, brand-assets, build-desktop-artifact, and invocation tests (105 tests).
• Full pipeline run from the tip of the stack: run 34682751893 with channel=preview built, signed (Developer ID + notarization, Trusted Signing), smoke-tested and published v0.0.41-preview.20260912.1589 with the three archives and SHA256SUMS (that run also published updater manifests and an npm tag, which the last commit removes from the workflow; see above).
• Downloaded the published linux-x64 archive on a separate machine, verified it against SHA256SUMS, and ran t3 --version and t3 serve from the extracted tree with an empty PATH (no Node installed in the environment); / returned 200 with the web client.

📝 Walkthrough

Walkthrough

The release system adds a preview channel with channel-specific versions, tags, npm distribution, platform CLI archives, checksums, smoke tests, and skipped hosted deployments. Runtime integrations classify preview builds with prerelease behavior.

Changes

Preview release channel

Layer / File(s)	Summary
Preview metadata and tag resolution scripts/resolve-nightly-release.ts, scripts/resolve-previous-release-tag.ts, scripts/*test.ts	Release metadata and tag resolution support nightly and preview channels with channel-specific versions, labels, and tags.
CLI archive packaging and smoke tests scripts/build-cli-archive.ts, scripts/smoke-cli-archive.ts, apps/server/resources/cli-entitlements.plist, apps/server/scripts/cli.ts, apps/server/vite.config.ts	The build scripts create signed platform archives with staged runtime contents. Smoke tests validate archive layout, version output, and service preflight behavior.
Preview workflow publication .github/workflows/release.yml	Preview workflows build archives, generate SHA256SUMS, attach release assets, publish preview npm artifacts, and skip AUR, hosted web, and Discord outputs.
Preview channel runtime integration apps/desktop/src/updates/updateChannels.ts, apps/server/src/cli/*, apps/web/src/branding.logic.ts, scripts/build-desktop-artifact.ts, scripts/lib/brand-assets.*, docs/operations/release.md	Runtime and build logic recognizes preview versions as prerelease builds. CLI invocation selects t3@preview, and release documentation describes the channel and archive process.

scripts/build-cli-archive.ts (1)

108-118: 🩺 Stability & Availability | 🔵 Trivial | ⚡ Quick win

Forward child output from every archive command.

ChildProcess defaults stdout and stderr to "pipe". runCommand does not consume these streams for commands other than vp install, so a chatty command can fill the pipe and block before exit. Set both redirections to "inherit" in runCommand.

child.exitCode is a branded ExitCode number. A signal termination fails the effect instead of returning null, so compare the value directly with 0 and remove Number(...).

run each target architecture on an architecture-specific runner instead of
relying on matrix.arch. Ensure the SEA build receives the intended architecture
and validate dist-exe/t3 before creating each archive, failing the job when the
executable is missing or has the wrong architecture.
