Two unblocking changes for first-contact flows.
Sender attribution: relay captures shortHash(senderSigningKey) at
PUT time (after signature verification, no new trust surface) and
surfaces it on bridge push (IncomingMessage.from) + inbox-fetch
(FetchedBlob.from) + DecryptHandler raw arg. Apps receiving a prekey
envelope from a never-before-seen peer can now bootstrap X3DH via
shade.receive('fp:<hex>', env) — pre-4.8 the wire envelope didn't
authenticate the sender and there was no out-of-band hint to use.
Idempotent ALTER TABLE migrations for SQLite + Postgres add a
sender_fp TEXT column; legacy rows surface as from=undefined
(inter-version compat).
Inbox.start() race: pre-4.8 start() called register() fire-and-forget
AND schedulePoll(0) synchronously, so the first poll on a fresh
address often beat the register HTTP RTT and got SHADE_NOT_FOUND.
start() now defers; register() success kicks schedulePoll(0). Manual
tick() is unaffected (deliberate user action, no gating).
Both reported by Prism. Tests cover all five acceptance criteria
from the sender-attribution request (PUT capture, bridge surface,
fetch surface, inter-version compat, end-to-end pair smoke) plus
the three from the race-fix request.

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.
