Root cause of 'two users can't chat': all accounts on one browser shared a single IndexedDB, so the second registration overwrote the first's Signal identity keys, corrupting both. Verified via two-isolated-client integration test (real crypto.js + store.js) that the protocol itself is correct. - store.js: useAccount(username) namespaces IndexedDB as cipher:<username>; keys generated at registration now persist under the right account - accounts.js: localStorage-backed account registry + active pointer - app.js: multi-account boot/activate, account-switch/add/logout menu, error toasts on send/decrypt failures (no more silent failures) - login guards against missing on-device keys (multi-device linking still TODO) - SW cache v2->v3 + precache accounts.js Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
