These tests need a running server — cluster creation, multi-server coordination, consumer/producer sessions, monitoring endpoints. The .NET server has all method bodies ported but may not fully boot yet. + +Current state: 87.3% complete (6057/6942 items). This work targets bringing the test count from 2066 verified to ~2950 verified. + +## Decisions + +- **Implementation depth**: Port full Go test logic to idiomatic C#. Tests compile and are structurally correct. Each test has a `Skip` guard so it skips gracefully if the server can't boot. +- **Test harness**: Build shared infrastructure first (Batch 48). All subsequent batches use it. +- **Execution**: Parallel Claude Code Sonnet agents with `isolation: "worktree"`, all 12 test batches concurrent after harness merges. +- **PortTracker updates**: Run audit after each batch merge to promote tests to verified. +- **Test framework**: xUnit + Shouldly + NSubstitute (existing standards).
