Scope and no-change assertion

Step 24 added no production behavior, no comparator/tolerance changes, and no reference artifact changes. The only implementation-owned source action during this step was running clang-format -i on four files that the dry-run style gate reported; git diff --raw, git diff --numstat, and git diff --check for those files were empty after the run, so no tracked source-content diff was introduced.

No Doxygen executable, hook entry point, scripts/execute.py, Abaqus, Nastran, reference solver, commit, or push was run.

Prior Step RED/GREEN/VERIFY evidence

The final gate reviewed the Executor-recorded Step 0-23 summaries. Each prior step is already completed in the phase index and retains its Executor-owned timestamps.

Step 24 is a final verification gate and did not manufacture a new RED condition; it reused the approved B33 and MITC4 reference comparisons after style and full build/test verification.

Handoff

Implementation gate verdict: pass-for-physics-evaluation.

Open issues: none blocking. The inherited FESA_HARNESS_CODEX_SANDBOX override is an environment note only; the clean child-process policy command passed without code changes.
