🎯 Functional Correctness | 🟠 Major | 🏗️ Heavy lift
Support distinct credentials for both Vertex providers
collectModels() allows both Vertex variants, but the first non-ADC path remains in env['GOOGLE_APPLICATION_CREDENTIALS']; the second provider cannot select another path. index.ts then generates one container path and one mount, and both provider clients resolve that same file as keyFilename. The second provider therefore uses the first provider’s service account and may fail when it requires different permissions. Require one shared credential file explicitly, or generate provider-specific credential references and mounts.

official Node.js fs accessSync chmodSync Windows mode bits documentation
💡 Result:
In Node.js, the behavior of fs.accessSync and fs.chmodSync regarding mode bits on Windows is significantly restricted compared to POSIX systems [1]. fs.accessSync The fs.accessSync(path, mode) method tests a user's permissions [2]. On Windows, access control policies (ACLs) can limit access to a file or directory; however, fs.accessSync does not check these ACLs [1]. Consequently, it may report that a path is accessible even if the user is restricted by an ACL [1]. Regarding the mode constants: - F_OK, R_OK, W_OK, and X_OK are supported [3]. - X_OK (execute permission) has no effect on Windows and behaves identically to F_OK [3]. fs.chmodSync The fs.chmodSync(path, mode) method is used to change the permissions of a file [4][5]. On Windows, its functionality is limited by the operating system's underlying file system capabilities [1]: - Only the write permission can be changed [1]. - The distinction between owner, group, and others is not implemented [1]. - Attempting to use mode bits to modify read or execute permissions will not have the intended effect, as these are not supported on Windows [1]. Because of these limitations, using fs.chmodSync on Windows to control granular access permissions is ineffective [1]. Developers are generally advised to rely on standard Windows file system permissions managed through the operating system rather than Node.js mode bits when working in a Windows environment [1].

Make the unreadable-file assertion portable.
validateCredentialPath uses accessSync(path, R_OK). The 0o000 mode does not reliably make this check fail for privileged processes, and chmodSync does not provide equivalent read-permission behavior on Windows. Guard the assertion on unprivileged POSIX systems or mock the filesystem access check.

Summary
Validation
No live Vertex API inference, production credentials, or license activation were used.
Note
Low Risk
Changes are limited to the setup wizard CLI and generated Compose/.env output; no runtime Sourcebot auth logic is modified.
Overview
Fixes setup-sourcebot so Google Vertex service-account JSON works when Sourcebot runs in Docker.
When users opt out of Application Default Credentials, the wizard now validates that the credentials path is a readable file (including
~expansion), keeps the host path only for Compose bind mounts, and writesGOOGLE_APPLICATION_CREDENTIALSin.envas the fixed in-container path/run/secrets/sourcebot-google-application-credentials.json.docker-compose.override.ymlis generated whenever Vertex file credentials or local repos need mounts. Repo and credential volumes use long-form read-only bind mounts with JSON-quoted sources so awkward host paths stay valid YAML.Adds a
testscript and unit tests for path validation and mount YAML, plus an Unreleased changelog entry.Reviewed by Cursor Bugbot for commit a4b3234. Bugbot is set up for automated code reviews on this repo. Configure here.
Summary by cubic
Fixes Google Vertex provider credentials in
setup-sourcebotso service-account files actually work when Sourcebot runs in Docker. The host path was previously written directly to.env, which doesn't resolve inside the container; the CLI now validates the file, mounts it read-only at/run/secrets/sourcebot-google-application-credentials.json, and writes that container path to.env.~and relative paths.Written for commit a4b3234. Summary will update on new commits.
