+## TEESimulator v4.2: Detection Evasion Hardening
+
+Fixes 6 detection vectors flagged by attestation validator apps.
+
+### Attestation Policy Enforcement
+
+Replicate AOSP keystore2's `add_required_parameters()` validation that our software keygen path was bypassing:
+
+- **CREATION_DATETIME** — Reject caller-provided input with `INVALID_ARGUMENT (20)`, matching `security_level.rs:424`. Our cert gen still adds its own timestamp, same as real keystore2.
+- **Device ID attestation** — Reject ATTESTATION_ID_SERIAL, IMEI, MEID, SECOND_IMEI, and DEVICE_UNIQUE_ATTESTATION with `CANNOT_ATTEST_IDS (-66)`. No consumer app has READ_PRIVILEGED_PHONE_STATE.
+- **Error reply format** — Fixed AIDL ServiceSpecificException parcel write order (was errorCode→message, now message→errorCode).
+
+### Certificate Fix
+
+Leaf certificate Subject CN corrected from "Android KeyStore Key" to "Android Keystore Key" (lowercase s), matching AOSP `KeyGenParameterSpec.java:282`. Both Kotlin and Rust paths.
+
+### Binder Timing
+
+Skip interception for system transaction codes (PING, INTERFACE, DUMP) above LAST_CALL_TRANSACTION. Eliminates the JNI round-trip that inflated binder ping ratio to 3.85x (detector threshold: 3.0x).
+

+
 ## TEESimulator v4.1: Boot Identity Persistence
 
 Bugfix release. The vbmeta boot key digest was randomizing on every reboot, producing a different RootOfTrust in attestation certificates each boot.
