android: V4.9 + V4.10 Kotlin ports + KeystoreStorage adapter
...
Cross-platform vectors / TypeScript vectors (bun) (push) Has been cancelled
Cross-platform vectors / Kotlin vectors (gradle) (push) Has been cancelled
Test / test (push) Has been cancelled
Pure-JVM additions to shade-android (no Android SDK needed):
- V4.9 blob primitives: BlobKdf (HKDF deriveBlobSlotId/Key/SigningSeed),
BlobAead (nonce||ct||tag with shade-profile-aad-v1:<slot> AAD),
BlobClient (java.net.http with hand-written canonical JSON signing
matching TS signPayload output), Profile high-level namespace.
- V4.10 approval helpers: CanonicalProfileBlob schema with denormalized
trustedApproverFingerprints, build/sign/verify proxy approvals via
length-prefixed u16 BE UTF-8 canonical signing payload.
- Password KDFs: scrypt + argon2id via Bouncy Castle, NFKC-normalized.
- SessionStateJson at-rest serializer for persistence layer.
Cross-platform vectors (test-vectors/blob.json, approval.json) gate
byte-identical output between TS and Kotlin, including a TS-signed
Ed25519 signature the Kotlin port verifies and reproduces (Ed25519 is
deterministic).
New shade-android-keystore sibling Gradle module (Android-specific):
- KeystoreMasterKey: hardware-backed AES-256-GCM with BIOMETRIC_STRONG
gating, StrongBox-backed when available, invalidated on enrollment.
- BiometricUnlock: coroutine wrapper around BiometricPrompt with
tagged cancellation/failure exceptions.
- KeystoreStorage: StorageProvider over biometric-gated AES-encrypted
SharedPreferences with AAD-bound row keys.
All 25 SDK packages typecheck clean; 104 SDK tests + 24 new Kotlin
tests + 11 cross-platform vector tests all green.

release(v4.0.0): Shade GA — V3.x consolidation + audit prep
...
Test / test (push) Has been cancelled
Cross-platform vectors / TypeScript vectors (bun) (push) Has been cancelled
Cross-platform vectors / Kotlin vectors (gradle) (push) Has been cancelled
Docker build and publish / docker (push) Has been cancelled
Publish / publish (push) Has been cancelled
V3.1 → V3.12 consolidated and tagged for the first GA release. Wire
format unchanged from 0.4.x — 4.0 peers interoperate with 0.4.x peers
byte-for-byte. The version bump is semantic: audit-cycle complete,
opt-in surface fully exposed, threat model refreshed for every new
surface.
Highlights:
- All 24 @shade/* packages bumped to 4.0.0 in lockstep.
- CHANGELOG 4.0.0 section is the canonical manifest of what landed.
- THREAT-MODEL extended (§10 fingerprint gates, §11 WebRTC P2P, §12
Web-Worker boundary) + residual-risks table refreshed.
- OpenAPI now covers all 27 routes: prekey, transfer, KT, inbox,
bridge, observer, /metrics, /healthz, /ready.
- MIGRATION 0.3.x → 4.0 documented + smoke-tested against
shade migrate-storage on a real SQLite DB.
- docs/audit/REVIEW-BUNDLE.md + SCOPE.md ready for external reviewer.
- scripts/soak.ts harness for the GA-stable 2-week soak window.
- All V*.md plans archived under docs/archive/ with Status: Done.
- Voice/Video carved out into V5.0; 4.0 audit focuses on the frozen
non-realtime stack.
Tests: TS 1000/1000 + Kotlin 11/11 cross-platform vectors green.
Docker: gt.zyon.no/stian/shade-prekey:4.0.0 builds and reports
version 4.0.0 on /health.

feat(android): M-Cross 1-3 — Kotlin module + cross-platform test vectors
...
Test / test (push) Has been cancelled
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.
