+- Move all tests to integration tests and test only via front door (Assert)
+- Expose Assert(() => x => y) overload method in Sharp class to delegate to included PowerAssert directly
+- Review dynamic support - make sure that dynamic = {...} objects are properly formatted
+- Custom formatters
+- Custom comparisons
+
+----
+
+Dynamic - only implement (general/binary). Need to be tested/extended to work properly with objects/collections/expando
+```csharp
+dynamic json = JsonSerializer.Deserialize<dynamic>(jsonString);
+Console.WriteLine(json.user.name);
+```
+
+```csharp
+dynamic person = new ExpandoObject();
+person.Name = "Yevhen";
+person.Age = 42;
+Console.WriteLine($"{person.Name} ({person.Age})");
+```
+

+
+**External diff viewers** - this is important to implement.
+- Need proper research. In pycharm when pytest assert fails it shows nice diff right inside ide using native means.
+- It would be cool impl similar for large multiline strings, or maps, etc. Need to think where this could be useful.
+
+----
+
+**Debugging the Rewriter** - not sure what value this will bring and what changes these requires.
+To facilitate debugging, the rewrite task will support a diagnostic MSBuild property:
+
+```xml
+<PropertyGroup>
+  <SharpAssertEmitRewriteInfo>true</SharpAssertEmitRewriteInfo>
+</PropertyGroup>
+```
+
+When enabled, the rewriter will output detailed logs of its analysis and decisions. This is crucial for troubleshooting unexpected rewrite behavior.
+
+----
+
+**Dependencies**
+- PowerAssert (current) — is not used anymore as automatic fallback for unsupported features (need to find all references to this fact and update)
+- DiffPlex — string & sequence diffs
+- Compare‑Net‑Objects — deep object diffs
+- Verify.*  — external diff tooling
+
+All these packages need to be properly attributed in README.md
+
+----
+
+**Rewriter Robustness & Fallback - pending**
+
+- Wrap rewriter logic in try-catch
+- If analysis fails, leave original Assert call
+- Add diagnostic logging controlled by MSBuild property - this looks like 4.3
+- Test with edge cases and invalid code
