Ship an official IndexedDB-backed StorageProvider so browser-based Shade
consumers persist identity, prekeys, sessions, retired identities,
peer-verification state and stream-resume rows across tab refresh and
browser restart. Closes the gap that forced browser apps onto
storage:"memory" (regenerated identity each load, orphaned device
records server-side).
- New package @shade/storage-indexeddb (4.3.0): full StorageProvider
conformance, schema v1, idb-backed; bumpPeerIdentityVersion is wrapped
in a single readwrite IDB transaction (atomic, vs SQLite's
read-then-upsert race).
- @shade/sdk resolveStorage() accepts { type: 'indexeddb', dbName? } via
dynamic import (lazy, optional dep — same pattern as
@shade/storage-postgres). Named StorageSpec type now reused by
ResolvedConfig.
- Tests: 16 new tests in shade-storage-indexeddb (StorageProvider
surface + peer-verifications + full E2EE conversation surviving a
simulated tab reload). Run on fake-indexeddb.
- Lockstep version bump 4.2.1 → 4.3.0 across all 25 packages.
- Publish scripts updated to include the new package.

@shade/recovery
Social key recovery for Shade — V3.10.
Shamir Secret Sharing over GF(2^8) splits the user's identity backup
key into n shares; any threshold-many k together reconstruct the
identity onto a new device. Distribution and reconstruction ride
existing 1:1 Shade sessions — no centralized recovery agent.
Install
bun add @shade/recovery
Quick wire-up
import {
setupRecovery,
attachGuardian,
requestRecovery,
MemoryRecoveryStore,
} from '@shade/recovery';
// Primary (Alice's existing device)
await setupRecovery({
shade,
guardians: ['bob', 'carol', 'dan', 'eve', 'faythe'],
threshold: 3,
deliver: async (to, envelope) => myOutbox.send(to, envelope),
});
// Each guardian
attachGuardian({
shade,
store: new MemoryRecoveryStore(), // swap for persistent store in prod
approve: async (ctx) => askUser(ctx),
deliver: async (to, envelope) => myOutbox.send(to, envelope),
});
// New device (Alice on a fresh phone)
await requestRecovery({
shade: tempShade,
originalAddress: 'alice',
setupId: '<from recovery card>',
threshold: 3,
guardians: ['bob', 'carol', 'dan', 'eve', 'faythe'],
deliver: async (to, envelope) => myOutbox.send(to, envelope),
});
