# Code Review — Step 1 Diagnostics subcommand

Result: **APPROVE**

## Findings

No blocking findings for the Step 1 diagnostics changes.

The previous R003 concern about default config-loader logs leaking raw config/env-file paths is addressed: the default diagnostics loader suppresses `slog.Default()` during config loading, and `TestRunDiagnosticsDefaultLoaderSuppressesPathLogs` covers secret/path leakage with the real loader.

## Verification performed

- `git diff ee86173..HEAD --name-only`
- `git diff ee86173..HEAD`
- Read changed implementation/tests for diagnostics, recent tool-call persistence, MCP catalog hashing, and server recording integration.
- `go test ./...` — passed.
- `make lint` — still fails, but only in files not touched by this Step 1 diff (`internal/app/setup.go`, `internal/mcp/protocol_test.go`).
