+### ScalaDoc NPE Fix (Feb 18, 2026)
+
+Scala 3.7.4's ScalaDoc crashes with NPE in
+`ScalaSignatureProvider.methodSignature` when rendering
+`inline` extension methods on opaque types. Deterministic on
+Linux x86_64 (CI), never reproduces on macOS ARM64.
+
+**Root cause**: `SignatureBuilder.content()` returns null for
+inline extension methods on opaque types with complex type
+parameter patterns.
+
+**Fix**: Removed `inline` from all Contents extension methods
+in `Contents.scala`. The compiler optimizes these trivial
+one-line delegations regardless of the `inline` keyword.
