+
+Two deprecation warnings pointed at `MIGRATION_GUIDE.md`, a file deleted from the
+repository in `8c5d20455` (objectui#6342).
+
+`Registry.register()`'s missing-namespace warning now points at the live docs page
+that documents namespaced registration
+(`/docs/guide/plugin-development#namespaced-registration`) instead of the deleted
+guide. `ValidationEngine`'s function-based-condition warning drops its `See:` line
+entirely: the deleted guide covered component namespaces and lazy field
+registration and never documented conditions at all, so that pointer was
+misdirected as well as dead, and the warning already carries the complete
+before/after migration inline.
+
+Both are console messages shipped to application developers, so neither can use
+the immutable `git show <sha>^:<path>` provenance form objectui#6275 used for a
+docblock — a reader of the npm package has no repository to run it against.
