No secrets in images	✅ Pass	No secrets present
--no-cache-dir on pip	✅ Pass	Correctly used in pip install

CI Build Failure Analysis

Check	Status
Build hoymiles-exporter / Build (linux/amd64)	failure
Build hoymiles-exporter / Build (linux/arm64)	failure
Build Success	failure
Build hoymiles-exporter / Plan	success

The multi-architecture builds for both linux/amd64 and linux/arm64 have failed. This indicates the Python 3.14 base image may have compatibility issues with either:

1. The application's Python dependencies in requirements.txt
2. Build tooling incompatibility with Python 3.14
3. Native extension compilation failures

The build logs would need to be examined to determine the specific failure cause.

Tool Harness Findings

The read_file tool successfully retrieved the full Dockerfile content, confirming:

• The updated FROM statement uses digest-pinned Python 3.14-slim
• All other Dockerfile instructions remain unchanged
• The structure follows repository conventions

Repository Impact

The repository impact scan shows this is not an isolated change—other apps in the repository still use Python 3.13 base images (e.g., bazarr, mylar3, qbittorrent, sabnzbd, webhook). The home-assistant app has already been updated to use Python 3.14 on Alpine.

This suggests Python 3.14 support may be viable for some apps but the hoymiles-exporter build is currently failing.

---

Required Action

The PR must be revised to address the CI build failures before it can be merged. The failure is not due to code quality or standards violations but rather a build compatibility issue with Python 3.14.

Options to resolve:

1. Investigate and fix the build failure cause specific to Python 3.14
2. If Python 3.14 is incompatible, close this PR and pin to Python 3.13 with a digest
3. Add any necessary compatibility adjustments to requirements.txt or build scripts

---

Unknowns / Needs Verification

1. Build failure root cause: The specific error message from the failed CI builds is not included in the corpus
2. Python 3.14 compatibility: Whether the hoymiles-exporter Python application and its dependencies are compatible with Python 3.14
3. Root fix verification: Once the PR is updated to fix the build, re-verification of CI success is required
