1. Pipeline module shadowing 🐞 Bug ✓ Correctness
Description
The newly added drug_discovery/pipeline/ package shadows the existing drug_discovery/pipeline.py
module, so drug_discovery.__getattr__ can no longer import DrugDiscoveryPipeline and CI’s
integration smoke test will fail.
Code

drug_discovery/pipeline/init.py[R12-19]

+from drug_discovery.pipeline.autonomous_pipeline import (
+    StreamingDataPipeline,
+    PipelineOrchestrator,
+    DataQualityMonitor,
+    FaultTolerantExecutor,
+    DataBatch,
+    PipelineCheckpoint,
+)
Evidence
drug_discovery.__getattr__ imports DrugDiscoveryPipeline from .pipeline, and CI’s integration
job imports DrugDiscoveryPipeline from drug_discovery. With a pipeline/ package present,
Python will resolve drug_discovery.pipeline to the package instead of pipeline.py, but the
package does not export DrugDiscoveryPipeline.

drug_discovery/pipeline/init.py[1-28]
drug_discovery/init.py[22-27]
drug_discovery/pipeline.py[21-32]
.github/workflows/ci.yml[102-110]

Agent prompt
The issue below was found during a code review. Follow the provided context and guidance below and implement a solution

### Issue description
A new package `drug_discovery/pipeline/` shadows the existing module `drug_discovery/pipeline.py`, breaking `from drug_discovery import DrugDiscoveryPipeline` used by CI and tests.

### Issue Context
`drug_discovery/__init__.py` lazily imports `DrugDiscoveryPipeline` from `.pipeline`. After this PR, `.pipeline` resolves to the newly-added package, which does not export `DrugDiscoveryPipeline`.

### Fix Focus Areas
- drug_discovery/pipeline/__init__.py[1-28]
- drug_discovery/__init__.py[22-27]

### Expected fix
Do one of:
1) Rename the new package directory (e.g., `drug_discovery/autonomous_pipeline/` or `drug_discovery/data_pipeline/`) and update imports accordingly; OR
2) Move the legacy `DrugDiscoveryPipeline` into the package and re-export it from `drug_discovery/pipeline/__init__.py` so `from .pipeline import DrugDiscoveryPipeline` continues to work; OR
3) Rename the legacy `pipeline.py` to a non-conflicting name and update the lazy import to that module, while maintaining backwards compatibility where required.

2. DataCollector breaks pipeline 🐞 Bug ✓ Correctness
Description
DataCollector.collect_from_pubchem now requires a positional query, and DataCollector no
longer provides collect_approved_drugs()/merge_datasets(), but the existing
DrugDiscoveryPipeline.collect_data() still calls those APIs and will raise
TypeError/AttributeError.
Code

drug_discovery/data/collector.py[R94-105]

+    def collect_from_pubchem(
+        self,
+        query: str,
+        limit: int = 100,
+        namespace: str = "name",
+    ) -> pd.DataFrame:
+        """
+        Collect molecular data from PubChem.
+
+        Args:
+            query: Search query
+            limit: Maximum number of compounds
Evidence
DrugDiscoveryPipeline.collect_data() calls collect_from_pubchem(limit=...) without a query,
and calls collect_approved_drugs() and merge_datasets(). The new DataCollector requires
query and does not define those methods, so the pipeline code path is broken.

drug_discovery/data/collector.py[94-99]
drug_discovery/data/collector.py[198-321]
drug_discovery/pipeline.py[60-99]

Agent prompt
The issue below was found during a code review. Follow the provided context and guidance below and implement a solution

### Issue description
Existing pipeline code calls DataCollector methods/signatures that no longer exist (missing `query` arg; missing `collect_approved_drugs` and `merge_datasets`). This will break runtime behavior and CI tests.

### Issue Context
`drug_discovery/pipeline.py` is used by CI/tests via `DrugDiscoveryPipeline.collect_data()`.

### Fix Focus Areas
- drug_discovery/data/collector.py[94-321]
- drug_discovery/pipeline.py[60-99]

### Expected fix
Make the new DataCollector compatible with the existing pipeline OR update the pipeline to use the new APIs:
- Change `collect_from_pubchem` to accept `query: Optional[str] = None` (defaulting to a safe query like &quot;aspirin&quot; or raising a clear error before network calls).
- Implement `collect_approved_drugs()` if it is part of the pipeline contract (even as a minimal local dataset stub), or update the pipeline to remove/replace this phase.
- Implement `merge_datasets()` in DataCollector (likely delegating to `DataNormalizer.merge_datasets()`), or update the pipeline to use `DataNormalizer` directly.
- Ensure `DrugDiscoveryPipeline.collect_data()` still works without requiring callers to change.

3. Normalizer filters raise KeyError 🐞 Bug ✓ Correctness
Description
DataNormalizer.apply_filters() unconditionally indexes descriptor columns (mol_weight, logp,
etc.), but the new tests call it on a DataFrame that only contains smiles, causing KeyError and
failing CI.
Code

drug_discovery/data/normalizer.py[R227-236]

+        filtered = df.copy()
+
+        if lipinski_filter:
+            # Lipinski's Rule of Five
+            filtered = filtered[
+                (filtered["mol_weight"] <= 500)
+                & (filtered["logp"] <= 5)
+                & (filtered["num_h_donors"] <= 5)
+                & (filtered["num_h_acceptors"] <= 10)
+            ]
Evidence
apply_filters() requires descriptor columns, but tests/test_data_layer.py passes a DataFrame
containing only smiles. Additionally, the tests expect normalize_dataframe() to output
canonical_smiles and inchikey columns which the implementation does not add.

drug_discovery/data/normalizer.py[157-172]
drug_discovery/data/normalizer.py[208-242]
tests/test_data_layer.py[55-84]

Agent prompt
The issue below was found during a code review. Follow the provided context and guidance below and implement a solution

### Issue description
`apply_filters()` assumes molecular descriptor columns exist and crashes on raw input DataFrames. Tests also expect `canonical_smiles` and `inchikey` columns from `normalize_dataframe()` but they are not produced.

### Issue Context
`tests/test_data_layer.py` calls:
- `normalize_dataframe(...)` then asserts `canonical_smiles` and `inchikey` exist
- `apply_filters(...)` on a DataFrame with only `smiles`

### Fix Focus Areas
- drug_discovery/data/normalizer.py[130-172]
- drug_discovery/data/normalizer.py[208-242]
- tests/test_data_layer.py[55-84]

### Expected fix
Choose one consistent contract and align code + tests:
- Option A (recommended):
 - In `normalize_dataframe`, add `canonical_smiles` and `inchikey` columns to the returned rows (and keep the canonical SMILES in the original `smiles` column if desired).
 - In `apply_filters`, if required descriptor columns are missing, compute them from SMILES (or call `normalize_dataframe(add_features=True)` internally) before filtering.
- Option B:
 - Update the tests to match the current implementation and ensure `apply_filters` validates prerequisites and raises a clear error message instead of KeyError.

Make sure CI tests pass and `apply_filters` is safe to call on minimally-shaped inputs.

4. Parquet dependency missing 🐞 Bug ⛯ Reliability
Description
DatasetVersioning persists datasets using to_parquet/read_parquet, but requirements-ci.txt
does not include a parquet engine (e.g., pyarrow), so versioning tests will fail at runtime in CI.
Code

drug_discovery/data/versioning.py[R78-86]

+        # Save dataset
+        dataset_path = self.versions_dir / f"{version_id}.parquet"
+        dataset.to_parquet(dataset_path, index=False)
+
+        # Create version entry
+        version_entry = {
+            "version_id": version_id,
+            "version_name": version_name,
+            "timestamp": timestamp,
Evidence
The implementation writes/reads parquet, and the test suite exercises these methods. CI installs
only requirements-ci.txt, which lacks pyarrow/fastparquet, so pandas parquet IO will raise an
ImportError.

drug_discovery/data/versioning.py[78-81]
drug_discovery/data/versioning.py[122-130]
requirements-ci.txt[1-22]
tests/test_data_layer.py[158-187]

Agent prompt
The issue below was found during a code review. Follow the provided context and guidance below and implement a solution

### Issue description
CI will fail when running DatasetVersioning tests because parquet IO requires an external engine not installed in `requirements-ci.txt`.

### Issue Context
`DatasetVersioning.create_version()` calls `DataFrame.to_parquet()`, and `load_version()` calls `pd.read_parquet()`. Tests execute these paths.

### Fix Focus Areas
- drug_discovery/data/versioning.py[73-81]
- drug_discovery/data/versioning.py[122-130]
- requirements-ci.txt[1-22]
- tests/test_data_layer.py[158-187]

### Expected fix
Implement one of:
- Add `pyarrow` (preferred) or `fastparquet` to `requirements-ci.txt` (and any other required requirements files), OR
- Change persistence format to one that has no extra dependency (e.g., CSV) or implement a runtime fallback (try parquet; if ImportError, fall back to CSV) and adjust tests accordingly.

Remediation recommended

5. Null-rate divide-by-zero 🐞 Bug ⛯ Reliability
Description
DataQualityMonitor.check_quality() computes null_rate by dividing by `len(data) *
len(data.columns) without guarding empty batches, which will raise ZeroDivisionError` when an
empty DataFrame is streamed.
Code

drug_discovery/pipeline/autonomous_pipeline.py[R74-80]

+        metrics = {
+            "timestamp": datetime.now().isoformat(),
+            "total_records": len(data),
+            "null_rate": data.isnull().sum().sum() / (len(data) * len(data.columns)),
+            "duplicate_rate": data.duplicated().sum() / len(data) if len(data) > 0 else 0,
+            "schema_valid": True,
+        }
Evidence
check_quality() performs the division unconditionally, and stream_data_batches() calls
check_quality(batch_df) for every batch when monitoring is enabled, so an empty batch will crash
the pipeline.

drug_discovery/pipeline/autonomous_pipeline.py[74-80]
drug_discovery/pipeline/autonomous_pipeline.py[286-292]

Agent prompt
The issue below was found during a code review. Follow the provided context and guidance below and implement a solution

### Issue description
`null_rate` calculation divides by zero for empty DataFrames.

### Issue Context
Streaming pipelines can yield empty batches (no new data, filtered batches, etc.).

### Fix Focus Areas
- drug_discovery/pipeline/autonomous_pipeline.py[74-80]

### Expected fix
Update `check_quality()` to handle empty DataFrames/zero columns safely, e.g.:
- compute `den = len(data) * len(data.columns)`
- set `null_rate = 0.0` when `den == 0`, otherwise `.../den`
Also consider aligning duplicate_rate similarly for the zero-column case.

A new package `drug_discovery/pipeline/` shadows the existing module `drug_discovery/pipeline.py`, breaking `from drug_discovery import DrugDiscoveryPipeline` used by CI and tests.

### Issue Context
`drug_discovery/__init__.py` lazily imports `DrugDiscoveryPipeline` from `.pipeline`. After this PR, `.pipeline` resolves to the newly-added package, which does not export `DrugDiscoveryPipeline`.

### Fix Focus Areas
- drug_discovery/pipeline/__init__.py[1-28]
- drug_discovery/__init__.py[22-27]

### Expected fix
Do one of:
1) Rename the new package directory (e.g., `drug_discovery/autonomous_pipeline/` or `drug_discovery/data_pipeline/`) and update imports accordingly; OR
2) Move the legacy `DrugDiscoveryPipeline` into the package and re-export it from `drug_discovery/pipeline/__init__.py` so `from .pipeline import DrugDiscoveryPipeline` continues to work; OR
3) Rename the legacy `pipeline.py` to a non-conflicting name and update the lazy import to that module, while maintaining backwards compatibility where required.

2. Datacollector breaks pipeline 🐞 Bug ✓ Correctness

DataCollector.collect_from_pubchem now requires a positional query, and DataCollector no
longer provides collect_approved_drugs()/merge_datasets(), but the existing
DrugDiscoveryPipeline.collect_data() still calls those APIs and will raise
TypeError/AttributeError.
Agent Prompt
### Issue description
Existing pipeline code calls DataCollector methods/signatures that no longer exist (missing `query` arg; missing `collect_approved_drugs` and `merge_datasets`). This will break runtime behavior and CI tests.

### Issue Context
`drug_discovery/pipeline.py` is used by CI/tests via `DrugDiscoveryPipeline.collect_data()`.

### Fix Focus Areas
- drug_discovery/data/collector.py[94-321]
- drug_discovery/pipeline.py[60-99]

### Expected fix
Make the new DataCollector compatible with the existing pipeline OR update the pipeline to use the new APIs:
- Change `collect_from_pubchem` to accept `query: Optional[str] = None` (defaulting to a safe query like "aspirin" or raising a clear error before network calls).
- Implement `collect_approved_drugs()` if it is part of the pipeline contract (even as a minimal local dataset stub), or update the pipeline to remove/replace this phase.
- Implement `merge_datasets()` in DataCollector (likely delegating to `DataNormalizer.merge_datasets()`), or update the pipeline to use `DataNormalizer` directly.
- Ensure `DrugDiscoveryPipeline.collect_data()` still works without requiring callers to change.

3. Normalizer filters raise keyerror 🐞 Bug ✓ Correctness

DataNormalizer.apply_filters() unconditionally indexes descriptor columns (mol_weight, logp,
etc.), but the new tests call it on a DataFrame that only contains smiles, causing KeyError and
failing CI.
Agent Prompt
### Issue description
`apply_filters()` assumes molecular descriptor columns exist and crashes on raw input DataFrames. Tests also expect `canonical_smiles` and `inchikey` columns from `normalize_dataframe()` but they are not produced.

### Issue Context
`tests/test_data_layer.py` calls:
- `normalize_dataframe(...)` then asserts `canonical_smiles` and `inchikey` exist
- `apply_filters(...)` on a DataFrame with only `smiles`

### Fix Focus Areas
- drug_discovery/data/normalizer.py[130-172]
- drug_discovery/data/normalizer.py[208-242]
- tests/test_data_layer.py[55-84]

### Expected fix
Choose one consistent contract and align code + tests:
- Option A (recommended):
  - In `normalize_dataframe`, add `canonical_smiles` and `inchikey` columns to the returned rows (and keep the canonical SMILES in the original `smiles` column if desired).
  - In `apply_filters`, if required descriptor columns are missing, compute them from SMILES (or call `normalize_dataframe(add_features=True)` internally) before filtering.
- Option B:
  - Update the tests to match the current implementation and ensure `apply_filters` validates prerequisites and raises a clear error message instead of KeyError.

Make sure CI tests pass and `apply_filters` is safe to call on minimally-shaped inputs.

4. Parquet dependency missing 🐞 Bug ⛯ Reliability

DatasetVersioning persists datasets using to_parquet/read_parquet, but requirements-ci.txt
does not include a parquet engine (e.g., pyarrow), so versioning tests will fail at runtime in CI.
Agent Prompt
### Issue description
CI will fail when running DatasetVersioning tests because parquet IO requires an external engine not installed in `requirements-ci.txt`.

### Issue Context
`DatasetVersioning.create_version()` calls `DataFrame.to_parquet()`, and `load_version()` calls `pd.read_parquet()`. Tests execute these paths.

### Fix Focus Areas
- drug_discovery/data/versioning.py[73-81]
- drug_discovery/data/versioning.py[122-130]
- requirements-ci.txt[1-22]
- tests/test_data_layer.py[158-187]

### Expected fix
Implement one of:
- Add `pyarrow` (preferred) or `fastparquet` to `requirements-ci.txt` (and any other required requirements files), OR
- Change persistence format to one that has no extra dependency (e.g., CSV) or implement a runtime fallback (try parquet; if ImportError, fall back to CSV) and adjust tests accordingly.

Any is used in return type annotations (e.g., -> Dict[str, Any]) but isn’t imported from typing. On Python 3.10 this will raise NameError at function definition time. Import Any (or enable postponed evaluation of annotations) to prevent runtime failures.

The conformal quantile calculation can produce q > 1 (e.g., small n with confidence_level=0.95), which will raise in np.quantile. Clamp q to [0, 1] and/or use the standard conformal quantile definition for nonconformity scores to avoid invalid quantiles.

calibrate_probabilities() builds a DummyClassifier and calibrates that model, which does not actually calibrate the provided predictions (the base estimator outputs a constant). If the goal is to calibrate an existing probability vector, use a calibrator that directly fits predictions to true_labels (e.g., isotonic regression / Platt scaling) and return the calibrated probabilities alongside the metrics.

normalize_dataframe() overwrites the input SMILES column with the canonicalized value, but it never creates the documented/expected canonical_smiles and inchikey columns. This makes the API misleading and causes the data-layer tests to fail. Consider preserving the original SMILES and adding explicit canonical_smiles + inchikey fields for downstream deduping/joins.

apply_filters() assumes descriptor columns (mol_weight, logp, num_h_donors, num_h_acceptors) already exist, but callers/tests pass DataFrames with only a smiles column. This will raise KeyError. Either compute descriptors inside apply_filters() when missing, or validate/raise a clear error instructing callers to run normalize_dataframe(add_features=True) first.

__getitem__() is annotated as returning Tuple[torch.Tensor, torch.Tensor], but for featurization="graph" it returns a dict of tensors for the feature. Update the return type annotation (and any downstream expectations) to reflect the actual union type to keep type-checking/IDE support accurate.

# Create a deterministic hash of the DataFrame

_compute_hash() uses pd.util.hash_pandas_object(data) with the default index=True, so identical datasets with different indices can produce different hashes (and thus different version IDs). Consider hashing with index=False and normalizing order (e.g., sort columns/rows) to make version hashes stable for identical content.

Suggested change
# Create a deterministic hash of the DataFrame
data_str = pd.util.hash_pandas_object(data).sum()
return hashlib.sha256(str(data_str).encode()).hexdigest()[:16]
# Normalize DataFrame to get a stable, content-based hash:
# - Sort columns so column order doesn't affect the hash.
# - Exclude the index so different indices with identical content
# produce the same hash.
normalized = data.sort_index(axis=1)
hashed_series = pd.util.hash_pandas_object(normalized, index=False)

null_rate divides by (len(data) * len(data.columns)) without guarding against empty batches or zero-column DataFrames, which can cause a ZeroDivisionError. Handle the empty-data case explicitly (e.g., treat null_rate as 0.0) to keep the streaming pipeline robust.

find_path() uses a Python list as a BFS queue with pop(0), which is O(n) per pop and can become a bottleneck on larger graphs. Use collections.deque for O(1) pops from the left.
