# Code Review — TP-078 Step 2

**Verdict:** APPROVE

## Findings

No blocking findings.

## Notes

- `setupPersistConfigAndKey` now stores and verifies the API key through `internal/credstore` before writing the generated config, which satisfies the main Step 2 failure-order requirement.
- Generated config now includes non-secret `credential_ref` metadata for the existing keychain service/account and continues to omit `api_key` and the secret value.
- Config loading remains backward-compatible with legacy JSON/.env API keys, while process env and keychain precedence behavior is preserved.

## Verification

- `go test ./internal/app ./internal/config`
- `go test ./...`
