Claud Opus 4.5 was used to assist with developing this PR
This code requires review and validation by NWS staff

Summary

This PR adds comprehensive CTest coverage for wave component jobs in the C48_S2SW workflow configuration. Five new test cases validate critical wave post-processing tasks, expanding the automated testing framework for the S2SW (Subseasonal-to-Seasonal with Waves) system.

Resolves #4318

Technical Notes

1. Wave History File Pattern: The uglo_100km history files follow a non-uniform pattern:

   • f000-f048: hourly (49 files)
   • f051-f120: every 3 hours (24 files)
   • Total: 73 files

2. Wave Point File Pattern: Point output files exist for all 121 hours (f000-f120)

3. Metatask Handling: The wavepostsbs task is a Rocoto metatask requiring specific subtask names (e.g., gfs_wavepostsbs_f000-f002) for rocotoboot

4. Task Output Separation:

   • wavepostbndpnt produces only ibp.tar
   • wavepostbndpntbll (separate task) produces ibpbull.tar and ibpcbull.tar

Baseline Reference

• Experiment: C48_S2SW_b40eab88-7222
• Location: /scratch3/NCEPDEV/global/role.glopara/GFS_CI_CD/HERA/BUILDS/GITLAB/stable/RUNTESTS

Dependencies

• Requires Rocoto dryrun build at GFS_CI_ROCOTO_PATH
• Uses fv3-cpu allocation on Hera
• Baseline data must be present at STAGED_CTESTS

Checklist

• YAML test cases follow existing patterns
• CMakeLists.txt entries use correct AddJJOBTest() format
• All 4 test phases pass for each test case (6 tests total)
• Input/output file paths match baseline structure
• Jinja2 templating with wxflow filters works correctly

Is this still a TODO?

Looks good. Just one question.
