📝 Walkthrough

Walkthrough

This PR contains two independent changes: disabling the GitHub Actions lint job via conditional configuration, and refactoring CSV parsing logic in the C++ pipeline code by replacing a generic template with two dedicated parsers for integer and float values.

Changes

CI Workflow

Layer / File(s)	Summary
Disable lint job .github/workflows/ci-build.yml	Job-level condition changed to if: false to prevent automated linting from running on pull requests.

CSV Parser Refactoring

Layer / File(s)	Summary
Parser implementations src/pipeline-synth-ops.cpp	Add <cerrno> header and implement two whitespace-tolerant dedicated CSV parsers: parse_csv_int using std::from_chars for locale-immune integer parsing, and parse_csv_float using std::strtof with errno-based overflow detection.
Integration with call sites src/pipeline-synth-ops.cpp	Update ops_resolve_params and ops_build_schedule functions to use the new parse_csv_int and parse_csv_float parsers instead of the generic parse_csv<T> template.

Poem

🐰 Two parsers hop where templates used to dwell,
With from_chars and strtof, no rounding bell,
The lint job sleeps with if: false so clear,
Whitespace-tolerant, robust and sincere! ✨

In `@src/pipeline-synth-ops.cpp`:
- Around line 53-74: parse_csv_float currently uses std::strtof which is
LC_NUMERIC dependent; update parse_csv_float to parse each numeric token in a C
locale to be locale-independent (e.g., create an std::istringstream for the
token, call ss.imbue(std::locale::classic() or std::locale("C")), then extract a
float via operator>> and check for stream errors) instead of calling
std::strtof; ensure you handle tokens that fail to parse by skipping/breaking
the loop as before and reference parse_csv_float when making the change.

Thanks for the report and the macOS testing!

I ended up going with a unified alternative on master: parse_csv stays as a single template, with a scan_num helper that overloads on int and float. The float overload uses std::from_chars normally and only falls back to a tiny hand rolled C locale parser when _LIBCPP_VERSION < 200000 (AppleClang). Mainline path stays byte identical on Linux and Windows, zero allocation everywhere.
