The split deploy smoke failed in CI with "The SHA-256 file could not be read." BuildKit's local exporter creates its output directory (`--output type=local,dest=$work/module-package`) with mode 0700, owned by whoever ran the build. That directory was mounted into the verifier, which runs as the image's unprivileged `node` user (uid 1000). In CI the build runs as root, so the directory was root:root 0700 and the verifier could read neither file; the digest file is simply read first. On a workstation the build runs as uid 1000, the same uid as `node`, so it was readable by coincidence. scripts/lib/module-package-release.sh turns one build's output into the release pair: it requires exactly one archive and its .sha256 and nothing else, checks that the digest line names that archive, then creates a fresh directory that must not exist yet (0755) and copies both files into it (0644). The smoke stages and mounts only that directory; BuildKit's output directory is never mounted. Archive-digest verification stays mandatory: the verifier still reads the .sha256 file. Nothing in the verifier changed. Tests: the helper is driven in bash against a 0700 build output, and refuses a missing, malformed, or mismatched digest, stray output, a second archive, and an existing release directory, creating nothing. A static test pins the smoke to the release pair and the verifier's single mount with --sha256-file. Co-Authored-By: Claude Opus 5.5 <[email protected]>
