Concerns: The runtime stage attempts to install a wheel with a name matching /dist/poetry-*.whl, but /dist actually contains the project's built wheel, not Poetry. This will fail at build time and result in a non-functional image., The final image relies on Poetry as the entrypoint, but Poetry is not installed in the runtime stage (the RUN pip install targets a non-existent wheel). This means the container may not have the Poetry CLI available when run as intended., If the goal is to ship a CLI tool via Poetry, consider either installing Poetry in the runtime image (e.g., via pip install --no-cache-dir poetry==${POETRY_VERSION}) or copying the Poetry wheel from a separate build artifact, then install the built project wheel. Alternatively, install the project wheel and set the entrypoint to the actual CLI script exposed by the package.

- Build status: build_failed
- Failing step: [builder 6/8] RUN poetry install --no-interaction --no-ansi (in Dockerfile)
- Exact error: The current project could not be installed: Readme path `/app/README.md` does not exist. Exit code: 1
- Command that failed: RUN poetry install --no-interaction --no-ansi
- Missing file: Readme path `/app/README.md` does not exist. Poetry attempted to install the current project and failed due to the missing README at /app/README.md.
- Context / environment:
  - Base image: python:3.12.13-bookworm
  - Debian apt installs a Python 3.11 stack side-by-side (libpython3.11, python3.11-dev, etc.)
  - Packaging adjustments during build: downgrades of packaging (26.0→25.0), virtualenv (21.2.0→20.36.1), pbs-installer (2026.3.10→2026.1.14), platformdirs (4.9.4→4.5.1)
  - Poetry version installed: 2.3.2
  - Log shows: Installing the current project: poetry (2.3.2) just before the failure; error arises during packaging, not dependency resolution
- Actionable notes / workarounds:
  - If you don’t want to install the current project as a package: run poetry install --no-root
  - Ensure pyproject.toml has packages configured
  - Add README.md at /app/README.md
- Additional observations:
  - The build copies a wheel named poetry-2.3.2-py3-none-any.whl from the builder stage; this wheel-name assumption is brittle if package name/version changes.

Concerns: COPY pyproject.toml poetry.lock* assumes a poetry.lock file exists; if the lock file is absent, the COPY may fail during build., Hard-coded wheel filename in COPY --from=builder /app/dist/poetry-2.3.2-py3-none-any.whl may break if the project name/version changes or the build outputs a differently named wheel., Smoke tests only verify version/CLI presence; consider adding a basic functional test (e.g., running a simple Poetry command) to ensure runtime behavior beyond --version.
Smoke [PASS]: poetry --version
Smoke [PASS]: poetry --help
