How to read this diff

Tracker release metadata, not direct proof of university publication timing.

Newly extracted claims are tracker additions and are not necessarily newly published by the university. Source snapshot changes mean the same URL produced a different hash; that may be policy text, layout, navigation, or metadata.

Tracker metadata only

This tracker is not legal advice, not academic integrity advice, and not an official university statement unless a linked source is the university's own official page.
