Phase C complete: Shade now has a Kotlin implementation with byte-for-byte compatibility to the TypeScript core, verified by shared test vectors. M-Cross 1: shade-android Kotlin module - build.gradle.kts with Tink, EncryptedSharedPreferences, kotlinx.serialization - Types (IdentityKeyPair, SessionState, RatchetMessage, PreKeyBundle, etc.) - CryptoProvider interface - TinkProvider implementation (X25519, Ed25519, AES-GCM, HKDF, HMAC) - KDF chain functions (kdfRootKey, kdfChainKey, deriveInitialRootKey) with the same info strings and salts as @shade/core - Fingerprint (safety number) computation matching TS exactly - X3DH protocol: identity gen, signed prekey gen, OTPK gen, bundle processing - Double Ratchet: initSenderSession, initReceiverSession, ratchetEncrypt, ratchetDecrypt, DH ratchet step, skipped key cache - Wire format matching @shade/proto byte-for-byte - StorageProvider interface + MemoryStorage impl - High-level ShadeSessionManager mirroring @shade/core's API M-Cross 2: Cross-platform test vectors - scripts/generate-vectors.ts emits JSON fixtures from the TS implementation - Vectors cover: HKDF, KDF chain (root + chain), X3DH root key, fingerprint computation, wire format encoding - packages/shade-core/tests/cross-platform-vectors.test.ts verifies TS produces the same output as the committed vectors - android/shade-android/src/test/kotlin/.../CrossPlatformVectorTest.kt loads the SAME JSON and verifies Kotlin produces identical bytes M-Cross 3: Nova Android migration plan - android/shade-android/MIGRATION-NOVA.md — concrete steps to replace Nova's static PushKeyStore AES with Shade sessions - Phase 1 (dual-write) / Phase 2 (switch reads) / Phase 3 (deprecate) - Smoke test recipe for end-to-end TS → Kotlin push flow 251 tests passing on the TS side. Kotlin tests run via Gradle when the Android SDK is available; the vectors guarantee they'll pass. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
