Nice library! Wanted to start with sth. small to get familiar, so I picked up #104

Moved the constants that were defined locally or hardcoded in a few places into constants.py and import them from there. No behavioiur change, same values everywhere with a small test so they don't drift back.

Summary by CodeRabbit

  • Improvements

    • Standardized default settings for graph connectivity, water-quality filtering, and edge-feature calculations across training, inference, and dataset workflows.
    • Centralized oxygen-related values and quality thresholds to ensure consistent results across processing stages.
    • Existing default behavior is preserved while reducing inconsistencies between workflows.
  • Tests

    • Added coverage to verify shared defaults and their use throughout relevant workflows.

📝 Walkthrough

Walkthrough

The change centralizes oxygen metadata, EDIA filtering defaults, graph cutoffs, and radial basis defaults in shared constants. Dataset, inference, confidence, utility, and script APIs now reference these constants. New tests verify values and references.

Changes

Shared default constants

Layer / File(s) Summary
Define shared constants and oxygen index
src/constants.py, src/confidence_dataset.py
src.constants adds shared oxygen metadata and the default minimum EDIA value. confidence_dataset.py imports OXYGEN_INDEX directly.
Apply shared defaults to core APIs
src/dataset.py, src/inference_graph.py, src/confidence.py, src/utils.py
Core dataset, graph, confidence, and edge-feature APIs now use shared defaults instead of duplicated literals.
Update script fallbacks and validate references
scripts/inference.py, scripts/predict_waters.py, scripts/train.py, tests/test_constants.py
Scripts use shared EDIA and cutoff defaults. Tests verify constant values and downstream signature references.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🟡 Moderate · up to b0cf3

The training command still uses a hardcoded graph cutoff instead of the shared default, so future updates could make training and graph construction behave differently. Update the CLI to use the centralized constant before merging.

Pull request overview

This PR consolidates previously scattered literal “defaults” (edge cutoff, oxygen vdW radius, oxygen element index, and minimum EDIA threshold) into src/constants.py, then updates call sites to reference the shared constants and adds a unit test to prevent regressions/drift.

Changes:

  • Added OXYGEN_VDW_RADIUS, DEFAULT_MIN_EDIA, and OXYGEN_INDEX to src/constants.py.
  • Replaced hardcoded defaults (8.0, 0.4, oxygen index derivations) with shared constants across src/ and scripts/.
  • Added tests/test_constants.py to assert constant values and ensure key APIs default to those constants (via signature inspection).
