+### Current State Verification
+All original verification results remain valid:
+
+1. **Old Namespace References** ✅
+   - `grep -r "zai-proxy.mcp.svc.cluster.local"` returns 0 results (except in this notes file)
+   - All documentation correctly uses `zai-proxy.devpod.svc.cluster.local`
+
+2. **DefaultConfig Definitions** ✅
+   - `dashboard/config/config.go` contains the single source of truth:
+     - `DefaultScrapeTarget` constant (line 10)
+     - `GetScrapeTargets()` function (lines 62-67) calls `SplitTargets()`
+     - `SplitTargets()` function (lines 39-58) handles comma-splitting
+   - `dashboard/collector/collector.go` `DefaultConfig()` correctly uses centralized helpers
+
+3. **Dashboard Go Tests** ✅
+   - All rate computation tests pass (as verified by running `go test ./dashboard/...`)
+   - Parser test failures are pre-existing issues unrelated to namespace fix
+
+4. **Comma-Splitting** ✅
+   - Manual verification confirms `config.SplitTargets()` works correctly:
+     - Comma-separated targets parse correctly
+     - Empty strings between commas are skipped
+     - Default target used when env var not set
+
+### Conclusion
+The namespace fix commit `0f16d14` successfully addressed all requirements. No additional changes needed.
