Chat: show a datetime on each message (bottom-right) - #308
Merged
Conversation
Visualize the per-message created_at (already persisted server-side and preserved by hydrateMessage on history load) as a compact local datetime in the bottom-right corner of every user prompt and assistant reply. The label reuses the collapsed session-group counter styling (text-[10px] text-text-faint/60 tabular-nums); full precision on hover. Live (just-sent / just-streamed) messages are created client-side without a server timestamp, so stamp them with the client clock at creation, so the current turn shows a time immediately without needing a reload.

What
Adds a compact local datetime to the bottom-right corner of every user prompt and assistant reply in the chat view.
text-[10px] text-text-faint/60 tabular-nums); full precision on hover viatitle.Aug 13, 2:41 AM(locale-aware; yearless, no seconds).How
Pure visualization of data that already exists: every message row persists
created_at,GET /api/sessions/{id}/messagesreturns it, andhydrateMessagealready copies it ontoChatMessageon history load. So historical/reloaded messages needed only a render.Live (just-sent / just-streamed) messages are built client-side without a server timestamp, so they're stamped with the client clock at creation — the current turn shows a time immediately without a reload. Stamp sites: optimistic send (
chatStore), assistant finalize done/stopped (streamingHandlers), backstop-finalize / answer-injected / cross-client user (sessionHandlers).Files
