+## Backlinking Convention
+
+Every `.org` file should link back to `roadmap.org` via a property:
+
+- Problem notes use `:NEETCODE:` linking to the roadmap heading
+- Toolkit/tricks use `:ROADMAP:` linking to a relevant problem
+- Roadmap entries use `:TRICK:` linking to relevant tricks
+
+This keeps the web of links navigable in both directions — from
+roadmap to notes, from notes to tricks, and tricks back to problems.
