What changed in this PR
This PR fixes cross-platform invocation of the internal ResultProcessor used by predictor baseline tests by ensuring absolute Unix paths are passed as values (not mis-parsed as /option switches), and by re-enabling -rp.txt generation/verification on non-Windows platforms.
Changes:
- Update the ResultProcessor test helper to pass inputs/outputs using
in=ando=withCmdQuoter, and fail the test when ResultProcessor returns a non-zero exit code. - Remove the Windows-only guard so
-rp.txtbaselines are generated and compared on Linux/macOS as well. - Add regression coverage for absolute paths (including spaces and braces) and add missing macOS arm64
-rp.txtbaselines.

Since this is handling UNIX (so both mac and linux), shouldn't we update the arm64 and arm linux baselines also? |

Fixes #26
Fixes Unix path handling in result-processor tests and re-enables
-rp.txtgeneration and baseline comparison on Linux and macOS. Absolute Unix input paths were interpreted as command-line options, preventing result-summary generation. A Windows-only guard had been masking this problem by skipping the affected checks.Changes
in=ando=arguments, usingCmdQuoterto escape them correctly.Baseline changes
While result-summary checks were disabled on Unix, some
-rp.txtbaselines fell out of sync with their corresponding platform-specific training-output (-out.txt) baselines.The corrected summaries match the existing training-output baselines. These changes repair stale or missing expectations, rather than alter training behaviour. Production code, shared baselines and comparison tolerances are unchanged.
