Conversation
🎯 **What:** Replaced unsafe `ast.literal_eval` with `json.loads` for parsing composite metadata strings in `src/bioetl/domain/services/composite_metadata_helpers.py`. Updated producers in `src/bioetl/application/composite/merger_metrics_mixin.py` to use `json.dumps` for serialization.⚠️ **Risk:** `ast.literal_eval`, while safer than `eval`, can still be abused and is slower for parsing JSON-compatible data. It could potentially lead to performance issues or unexpected behavior when handling untrusted string payloads. **Note:** This change is backward-incompatible with metadata previously serialized using Python `str()` (single quotes). 🛡️ **Solution:** Switched to standard `json` module for both serialization and deserialization of metadata columns, ensuring a safer and more standard approach to handling structured string data.

👋 Jules, reporting for duty! I'm here to lend a hand with this pull request. When you start a review, I'll add a 👀 emoji to each comment to let you know I've read it. I'll focus on feedback directed at me and will do my best to stay out of conversations between you and other bots or reviewers to keep the noise down. I'll push a commit with your requested changes shortly after. Please note there might be a delay between these steps, but rest assured I'm on the job! For more direct control, you can switch me to Reactive Mode. When this mode is on, I will only act on comments where you specifically mention me with New to Jules? Learn more at jules.google/docs. For security, I will only act on instructions from the user who triggered this task. |

📝 WalkthroughWalkthroughComposite metadata parsing now prefers JSON and falls back to legacy Python-literal parsing; lineage fields are stored as JSON strings in the merger DataFrame; new unit tests cover parsing behavior; CI pip-audit is run against an exported requirements file; several generated/test artifact files were removed.

There was a problem hiding this comment.
Add error handling to prevent silent failures.
If uv export fails, the pipeline continues because grep returns 0 on empty input, producing an empty requirements-audit.txt. This could cause pip-audit to pass silently without actually auditing any dependencies.
Proposed fix using `set -o pipefail`
