Build Archipelago ISO (dev) / build-iso (push) Failing after 11m1s
v1.7.38 and v1.7.39 both shipped with `./` inside the frontend tarball marked drwx------ (700). Tar extraction preserves archive perms, so every node that pulled the OTA landed with /opt/archipelago/web-ui at 700, nginx (www-data) returned 500 "permission denied" on every page, and the browser showed "Internal Server Error nginx". .116 hit this on both v1.7.38 and v1.7.39 rollouts. The v1.7.39 runtime self-heal in main.rs was the wrong layer — systemd's ReadOnlyPaths namespace made /opt/archipelago read-only from inside the archipelago service, so chmod from there returned EROFS. Root cause: create-release-manifest.sh used mktemp -d (700 default umask) for staging, then tar preserved that 700 in the archive's root entry. Fix the archive itself: - chmod 755 staging dir + `find -type d -exec chmod 755` + `-type f chmod 644` before tar, so the on-disk entries are correct. - tar --owner=0 --group=0 --mode='u=rwX,go=rX' to normalize archive perms belt-and-braces in case file-mode drift ever reappears. - Post-tar verify: `tar tvzf | head -1` must show drwxr-xr-x at root, or the release script aborts before the manifest is even generated. Binary unchanged semantically — the main.rs self-heal stays in as a last- resort belt (can't hurt on nodes whose FS isn't namespace-isolated), and the update.rs in-extractor chmod stays in so v1.7.40-onwards extractors are double-safe. The authoritative fix is the archive. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
