Function names may differ from what you expect: +```bash +grep "export function\|export async function\|export const" server/_core/kycHardening.ts +``` + +### Key Test Files +- `server/tests/platform-hardening.test.ts` — 99 assertions for all 44 recommendations +- `server/tests/audit-gap-adversarial.test.ts` — 64 adversarial assertions for 19 gap fixes +-

## Devin Secrets Needed -None — all testing uses the dev-login bypass and local PostgreSQL with hardcoded credentials in `.env`. +- `OAUTH_SERVER_URL` — Required for dev server to boot +- `BUILT_IN_FORGE_API_KEY` — Required for dev server to boot +- `BUILT_IN_FORGE_API_URL` — Required for dev server to boot + +## Tips +- The Python platform-hardening service (port 8270) is the easiest to test at runtime (no auth required, starts quickly, has biometrics/anomaly/canary/liquidity endpoints) +- The Python reconciliation engine (port 8170) has insider threat analytics (collusion, FX verification, admin anomaly) +- Go and Rust services may not have standalone `go.mod` — verify structurally via grep, not compilation +- For tRPC route testing, vitest is more reliable than trying to boot the dev server without env vars +- Always test BOTH positive (should detect) AND negative (should not detect) cases to catch inverted logic +- When writing adversarial tests, read the actual implementation first to get correct function names, field names, and return types — don't assume +- Python services use snake_case fields; TypeScript uses camelCase — mismatches are a common test failure source +- For Kafka topic parity checks, grep all three services (Go/Python/TypeScript) for the same topic strings +- Structural verification (grep for SQL patterns, API references) is useful when live middleware isn't available +- Base branch has 13 pre-existing test failures (fund-flow-safety, agent-cash-pickup, smoke) — these are NOT regressions diff --git a/client/src/i18n/locales.ts
