Architecture
- Protected assets and abuse outcomes are documented.
- Client, platform, attestation service, and backend trust boundaries are drawn.
- Signals, confidence, freshness, binding, decision, and response are separated.
- Offline and dependency-failure behavior is approved.
- Critical authorization remains server-side.
Implementation
- Protected builds are reproducible and identifiable.
- SDK or transformation versions are pinned and inventoried.
- Android and iOS signing and symbol workflows are verified.
- Backend contracts reject self-asserted client trust.
- Performance, privacy, and accessibility budgets are defined.
Testing
- Release-equivalent artifacts are used.
- Threat-led, bypass, negative, and regression cases are versioned.
- The device and OS matrix reflects the real fleet.
- App, transport, backend decision, and business outcome are captured.
- Residual risk is reported without absolute language.
Operations
- Events preserve facts separately from conclusions.
- Policy changes are versioned, approved, staged, and reversible.
- SOC, fraud, support, privacy, and engineering ownership is clear.
- Protection absence and provider failure are monitored.
- Incidents and false positives create regression tests.
Procurement
- Candidates test the same scenarios in representative code.
- Platform parity and unsupported combinations are disclosed.
- Data flows, residency, retention, and deletion are documented.
- Update, vulnerability, support, and incident SLAs are contractual.
- Policy export, de-instrumentation, and exit support are defined.
