-The .NET port has grown significantly from the prior baseline (~27K→~38.8K lines). All 15 original gaps have seen substantial growth. However, many specific features within each subsystem remain unimplemented. This document catalogs the remaining gaps based on a function-by-function comparison.

-The .NET test suite (3,168 test methods) achieves good coverage breadth but many tests validate API contracts against stubs/mocks rather than testing actual distributed behavior. The gap is in test *depth*, not test *count*.
+The .NET test suite has **5,808 test methods** (expanding to ~6,409 with parameterized `[Theory]` test cases). Of these, **2,485** (42.8%) are linked back to Go test counterparts via the `test_mappings` table (57,289 mapping rows). The remaining 3,323 .NET tests are original — covering areas like unit tests for .NET-specific implementations, additional edge cases, and subsystems that don't have 1:1 Go equivalents.
