SIMPLE src/main/params
This folder owns the typed parameters object and the parse/derive/validate
pipeline behind params%new(cline) and builder parameter initialization.

Parameter Lifecycle
To add or change a command-line parameter:
- Declare the field and declaration-time default in
simple_parameters.f90.
- Bind command-line parsing in
simple_parameters_parse.f90 with the matching
registry call, such as add_char, add_int, add_real, add_file, or add_dir.
- Derive dependent values in the right phase of
simple_parameters_phases.f90.
- Add mode restrictions and sanity checks in
validate_parameter_consistency.
- Touch
simple_parameters_core.f90 only for dynamic string defaults or shared
lifecycle utilities.
Working Rules
- After parsing, consume typed
params%... fields in workflow logic.
- Use
cmdline mainly before parsing, for command-shape validation, and for
constructing sparse child command lines.
- Keep parser registration and validation close to the parameter's ownership.
- Check existing derived logicals before inventing new downstream tests. For
example,
filt_mode currently derives l_lpauto, l_nonuniform, and
l_nonuniform_lpset.
