Older-messages pagination (couple of chats wouldn't scroll back): the thread query
returned the latest 40 rows and JS filtered out hidden (delete-for-me) messages
AFTER the LIMIT, so a chat with a hidden recent message returned <40 → the client
read that as "no older history." Now excluded in SQL (repos.thread /
threadByConversation take the viewer id), so a page is always 40 VISIBLE rows.
Verified locally: hide 3 recent → page still returns 40 (older ones fill in).
#2 iOS in-chat tone was silent: WebAudio context is created suspended and only
resumes inside a user gesture. Added unlockAudio() on first tap/click (resume +
0-gain blip), re-armed each gesture so a background→foreground re-suspend recovers.
#9 Long-press "works once then stops" on images was iOS's native touch-callout
(Save Image / selection magnifier) hijacking the gesture. Disabled
-webkit-touch-callout/user-select on #msgs bubbles; added a Save action to the
sheet so image-saving isn't lost.
#13 Pin/unpin WAS being audited (verified: message.pin in /api/audit) — there's just
no in-app viewer. Surfaced "Pinned by X" in the pinned bar for immediate context.
#14 Hardened draft save: it now runs BEFORE maybeAutocorrect/autoGrow (wrapped) in the
input handler, so a throw there can't skip persisting the draft.
