You are helping me submit a MODIFICATION of L2-508-001 (Optical Coherence Elastography (OCE) — Spec Skeleton) to the PWM Protocol — a Digital Twin (L2) artifact.

I will paste a Markdown template (or the current L2-508-001.md).
1. Rewrite the Markdown so the science is correct and clearly explained for my change.
2. Regenerate the sibling L2-508-001.json so EVERY field matches the Markdown.
3. Keep the schema in the "File Mapping" footer at the bottom of the MD.
4. Keep the parent reference unchanged unless I ask otherwise.
Rules: the Markdown is the source of truth; use SI units; do NOT invent benchmark scores.
Output each file in its own fenced code block tagged with the filename.
