Several localStorage caches held decrypted message content or user PII and
survived a normal logout, leaving residue on a shared device (the search
index was already wiped; these were not):
- cinny_scheduled_messages_v1 - decrypted IContent.body of pending sends
- cinny_recent_searches_v1 - search query text
- cinny_recent_forward_targets_v1 - recent forward contact/room graph
- cinny_recent_gifs_v1 / cinny_recent_stickers_v1 - media the user sent
- navToActivePath<userId> - per-space last-visited room paths
- (plus the translation cache added earlier)
Add a clear function per module and a single auditable clearPlaintextCaches()
aggregator, called from both logout paths (logoutClient + the server-forced
SessionLoggedOut handler) alongside the existing session/search-index wipes.
Unit-tested.
Deliberately NOT cleared (documented in the aggregator): unsent composer
drafts and the presence status message (preserved by product decision N98);
SDK sync/crypto store + io.lotus.* account data (reminders/bookmarks/notes),
already wiped by mx.clearStores(); low-sensitivity UI/metadata residue.
The forward-targets/gifs/stickers/nav-path additions and the accurate
"not covered" documentation address findings from two review passes.
