updates-99: stuck-stop fix, calendar prefetch, chart polish#208
Conversation
- AssistantChat: nuclear stop now also unblocks submission (sets isRunning=false immediately), fixing the "queueing forever" state after a tab refresh + stop during reconnect. Moves the stop button to extraActionButton and tones down its color so it doesn't compete with send. - TiptapComposer / SqlChart / SqlChartCard: small UI polish.

Review Details
Code Review Summary
This PR addresses three issues: (1) the "stuck queueing forever" state in AssistantChat after a tab refresh + stop during reconnect, (2) instant calendar navigation via adjacent range prefetch, and (3) chart UI polish. The total change is 105 lines across 7 files (Risk: Standard).
Approach Assessment
Nuclear stop refactor: The implementation unblocks submission immediately by making isRunning = !forceStopped && (...). This solves the user-facing wedged state but introduces a race condition with server-side run persistence — users can now submit new messages before the previous run has fully aborted on the server, creating a window where the old run's partial output could persist after the new message is sent.
Calendar prefetch: The intent (prefetch adjacent ranges for instant j/k navigation) is sound and well-implemented, but the guard condition (if (isLoading) return) doesn't account for React Query's placeholderData: keepPreviousData, which keeps isLoading=false while the new range is fetching.
Key Findings
🟡 MEDIUM (2 issues):
- Line 1068 (AssistantChat.tsx):
forceStoppednow gates real submission state, allowing new messages to submit before previous run completion. Potential race with server-side run persistence if the tab disconnects before the new message is saved. - Line 151 (CalendarView.tsx): Prefetch guard only checks
isLoading, but withplaceholderData: keepPreviousData, navigating doesn't triggerisLoading=true. Adjacent prefetches fire concurrently with primary fetch on every navigation, multiplying requests.
✅ Good patterns:
- Stop button placement as
extraActionButton(alongside send, not replacing it) matches Claude cowork pattern - Query key deduplication and staleTime/gcTime settings are correct
- Component prop additions are backward-compatible
🧪 Browser testing: Will run after this review (PR touches UI behavior in chat and calendar views).

🟡 forceStopped now gates submission state, risking race with server run persistence
The new isRunning = !forceStopped && (...) makes submissions possible immediately after Stop, but the previous run may still be aborting on the server. If the user submits quickly, the server could persist the old run's partial output before the new user message is saved to the database, causing loss or out-of-order history on reconnect.

🟡 Prefetch concurrency: adjacent ranges fetch while primary range is loading
The guard if (isLoading) return doesn't account for placeholderData: keepPreviousData in useEvents(). Navigating keeps old data visible, so isLoading stays false while the new range is still fetching. This causes adjacent prefetches to run concurrently with the primary fetch on every navigation, multiplying requests against Google Calendar and external feeds.
