docs: add CALYPSO model deviation arginfo

[njzjz-bot]

Summary

• Add CALYPSO-specific model_devi_engine argument metadata for generated configuration docs.
• Normalize single-item list values used by the existing CALYPSO examples before generating input.dat.
• Allow scalar PSTRESS values by normalizing them to the pressure list used for CALYPSO work directories.

Context

This follows up on #1795. While reviewing that PR, I found two issues:

• pre-commit failed on formatting/trailing whitespace;
• several documented single-item list forms (for example PopSize: [5] and fmax: [0.01]) were not normalized before reaching make_calypso_input(), which expects scalar values.

Tests

• uvx pre-commit run --files dpgen/generator/arginfo.py dpgen/generator/lib/make_calypso.py dpgen/generator/run.py tests/generator/test_calypso.py
• uv run --with pytest pytest tests/generator/test_calypso.py -q

Summary by CodeRabbit

• New Features

  • Enhanced CALYPSO model-deviation engine with comprehensive configuration options for structure generation, optimization parameters, and convergence criteria.
  • Improved input parameter handling with automatic normalization for more flexible configuration formats.

• Tests

  • Added validation test for parameter normalization in model-deviation workflows.

📝 Walkthrough

Walkthrough

Adds a complete model_devi_calypso_args() argument schema for the CALYPSO engine and wires it into model_devi_args(). Introduces two normalization helpers—_normalize_calypso_scalar and _normalize_calypso_pressures—applied inside _make_model_devi_native_calypso and run.py to standardize scalar/list input shapes. A new test validates single-item list acceptance.

Changes

CALYPSO Engine Schema and Input Normalization

Layer / File(s)	Summary
CALYPSO arginfo schema and engine wiring dpgen/generator/arginfo.py	Introduces model_devi_calypso_args() with a repeatable model_devi_jobs list schema covering species/composition, distance constraints, PSO/optimization controls, VSC options, and convergence targets, plus top-level calypso_input_path, model_devi_max_iter, and vsc fields. Wires it into the calypso variant of model_devi_engine in model_devi_args(), replacing the previous empty placeholder.
Normalization helpers, application, and test dpgen/generator/lib/make_calypso.py, dpgen/generator/run.py, tests/generator/test_calypso.py	Adds _normalize_calypso_scalar (raises on multi-item lists, unwraps single-item lists) and _normalize_calypso_pressures (wraps non-list values into a list). Applies the scalar normalizer to Volume, PsoRatio, PopSize, MaxStep, ICode, MaxNumAtom, and fmax inside _make_model_devi_native_calypso, and the pressure normalizer to PSTRESS there and in run.py before per-pressure subdirectory generation. New test asserts correct input.dat output when job fields are single-element lists.

❌ Failed checks (2 warnings)

Check name	Status	Explanation	Resolution
Title check	⚠️ Warning	The PR title 'docs: add CALYPSO model deviation arginfo' is misleading; the changeset primarily implements normalization logic for single-item list values and pressure handling, with documentation metadata being only one aspect.	Consider a more comprehensive title like 'Add CALYPSO model deviation arginfo and normalize input values' that reflects both documentation and functional changes.
Docstring Coverage	⚠️ Warning	Docstring coverage is 18.18% which is insufficient. The required threshold is 80.00%.	Write docstrings for the functions missing them to satisfy the coverage threshold.
