Research Frontmatter Standard

Ensure all research files in docs/research/ have standard YAML frontmatter so GitHub renders metadata as a table and readers can judge staleness.

Required Frontmatter

Every research file MUST have these 5 fields at the top of the YAML block:

---
title: "Human-readable title"
version: "1.0.0"
status: Published           # Published | Draft | Living Document
created: YYYY-MM-DD
last_updated: YYYY-MM-DD
---

Additional fields (slug, tags, aliases, promoted_at, last_refreshed, sources) MAY follow the standard fields.
