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.

* V3.11 acceptance criterion (loopback flavour): a multi-lane payload

* payload over HTTP-loopback.
|

*
|

* The MemoryRtcFactory short-circuits the network entirely, so this is
|

* effectively comparing "in-process pipe" vs "HTTP-loopback round-trip"
|

|
||||
* stack on the HTTP side. This stand-in test validates the wiring; the

* "real" same-LAN comparison runs in `webrtc-native.test.ts` when
