Release policy: latest desktop builds and OAuth

This runbook describes how we avoid users completing OAuth (including Gmail) on outdated desktop installers while the canonical flow is the latest release.

Distribution

• GitHub Releases for tinyhumansai/openhuman are the primary source for desktop builds.
• The Tauri updater endpoint (see scripts/prepareTauriConfig.js and release workflows) should point users at the current release artifacts.
• Retiring old stable artifacts: When dropping a release line, remove or hide obsolete installer assets on GitHub Releases, update website / CDN download links to releases/latest (or current), refresh the updater manifest (e.g. Gist / latest.json) so it does not point users at deprecated builds, and spot-check that old direct URLs are redirected, 404, or 410 where appropriate. Verification: try known-old asset URLs from docs or bookmarks and confirm they no longer deliver primary install paths.

Minimum app version for OAuth

Production web builds embed a minimum supported app semver at build time so OAuth deep links cannot complete on deprecated binaries. Each installer carries the floor that was set when that build was produced; raising the floor for users who never upgrade requires a new release they install (or in-app update). Optional future work: enforce a moving minimum via a runtime API with the bundled value as fallback only.

Variable	Purpose
VITE_MINIMUM_SUPPORTED_APP_VERSION	e.g. 0.51.0 — desktop app must be ≥ this to finish openhuman://oauth/success.
VITE_LATEST_APP_DOWNLOAD_URL	Optional; defaults to https://github.com/tinyhumansai/openhuman/releases/latest. Opened when the gate blocks OAuth.

Configure these as GitHub Actions variables. They must be present on both the standalone pnpm build step and the tauri-apps/tauri-action step env in .github/workflows/release.yml and build-windows.yml so the Vite bundle embedded in shipped installers includes the gate. Leave VITE_MINIMUM_SUPPORTED_APP_VERSION unset for local dev (gate disabled).

Implementation: app/src/utils/oauthAppVersionGate.ts, app/src/utils/desktopDeepLinkListener.ts.

Gmail / Google Cloud OAuth

• Redirect URIs in Google Cloud Console must match the current backend + tunnel callback paths.
• The desktop scheme (openhuman://) is stable; the installed binary must meet the minimum version when VITE_MINIMUM_SUPPORTED_APP_VERSION is set.

Release checklist (avoid regressions)

1. Bump app/package.json and app/src-tauri/tauri.conf.json (and root Cargo.toml / core) per existing version workflows.
2. When dropping support for older installs, set VITE_MINIMUM_SUPPORTED_APP_VERSION to the new floor before or with that release (repo Actions variables + both workflow steps above).
3. Remove, redirect, or retire older stable installers and stale updater entries from user-facing surfaces (GitHub Release assets, website, CDN, updater feed). Confirm deprecated artifacts are not reachable from default install/update flows.
4. Smoke-test Gmail connect on a fresh install from releases/latest.
