- Failing step:
  - [5/5] RUN python -m pip install --upgrade pip setuptools wheel     && pip install -e .[test]

- Exact error message and exit code:
  - ERROR: process "/bin/sh -c python -m pip install --upgrade pip setuptools wheel     && pip install -e .[test]" did not complete successfully: exit code: 1
  - error: failed-wheel-build-for-install
  - × Failed to build installable wheels for some pyproject.toml based projects
  - ╰─> rpds-py
  - error: failed-wheel-build-for-install
  - The overall failure: process "/bin/sh -c ..." did not complete successfully: exit code: 1

- Missing packages or files mentioned:
  - rpds-py wheel build failed due to PyO3 compatibility; rust/Cargo steps invoked (Rust tooling installed temporarily for building a native extension) but ultimately failed due to version mismatch.

- Version mismatch / compatibility info:
  - error: the configured Python version (3.15) is newer than PyO3's maximum supported version (3.14)
  - = help: this package is being built with PyO3 version 0.27.2
  - = help: check https://crates.io/crates/pyo3 for the latest PyO3 version available
  - = help: updating this package to the latest version of PyO3 may provide compatibility with this Python version
  - = help: set PYO3_USE_ABI3_FORWARD_COMPATIBILITY=1 to suppress this check and build anyway using the stable ABI

- Note:
  - The failure occurs during building rpds-py wheels as part of editable install via pip install -e .[test]. The Python version (3.15) is not compatible with the PyO3 version in use (0.27.2).

Summary (under 1500 chars):

- Exact error message and exit code
  - exit code: 9
  - Error: useradd: group builder exists - if you want to add this user to that group, use -g.

- Failing command/step
  - [ 8/10] RUN groupadd -r builder && useradd -m -r -s /bin/bash builder

- Missing packages or files mentioned
  - None reported as missing; the failure is due to an existing group named "builder" causing useradd to fail.

- Version mismatch info
  - Base image: python:3.12-slim (sha256:7026274c107626d7e940e0e5d6730481a4600ae95d5ca7eb532dd4180313fea9)
  - OS/distro context: Debian trixie; no explicit version mismatch noted in the log.

- Quick remediation hint
  - If the group already exists, skip groupadd (or use groupadd -r builder || true) or add the user to the existing group with: useradd -m -r -s /bin/bash -g builder builder.
