 # Articles
 
-Articles are standalone technical arguments designed to remain useful when a reader arrives directly from a search engine, newsletter, social link, conference resource list, or external citation. They are not curriculum stages and do not require prior Learning material.
+ASI Backbone Learning articles are standalone technical arguments written for direct discovery, sharing, and citation. A reader can arrive from a search engine, newsletter, social link, conference resource list, or external reference without completing the Learning curriculum first.
 
-A published article keeps a stable address of the form:

+## Publication Model
+
+Articles are not curriculum stages and do not require prior Learning material.
+
+Each published article keeps a stable year-and-slug address:
 
 ```text
 https://asibackbone.github.io/Learning/articles/<year>/<slug>.html
 ```
 
-Once released, that year-and-slug URL is treated as permanent. Reorganizing tutorials, architecture pages, security material, or other curriculum content does not move an article.
+Once released, that URL is treated as permanent. Reorganizing tutorials, architecture pages, security material, or other curriculum content does not move an article.
 
 The Learning site is the canonical publication host. Cross-posted copies should point back to the Learning article when the external platform supports canonical attribution.
