Introduce ChatQuotaExhaustedBanner component that displays a pink gradient
banner with an "Unlock your membership to continue" CTA when a guest user's
free chat quota has been exhausted. The banner is shown in ChatScreen when
isGuest is true, quota has loaded, and the chat state machine's
quotaExceededTrigger has been incremented by a quota guard. Default click
navigates to /subscription, with an optional onUnlock callback for
overrides/tests. Styles align with the existing splash and sidebar VIP
card visual language.
Remove `**...**` emphasis markers from inline comments and JSDoc blocks across
auth and chat components, machine mappers, and quota helpers. These are
plain code comments, not rendered markdown, so the bold syntax was noise.
Files touched:
- src/app/auth/components/auth-screen.tsx
- src/app/chat/components/chat-header.tsx
- src/app/chat/components/chat-screen.tsx
- chat machine mapper / quota helpers
No functional or behavioral changes.
- Remove unused `quotaWarningThreshold` and `warningThreshold` getter from `GuestChatQuota` DTO
- Apply get-or-init pattern in `ChatStorage.getGuestDailyChatQuota` and `getGuestTotalQuota`: when no existing value, initialize with DTO defaults (`threshold` = max per day, `totalQuotaDefault`) and return the seeded data
- Fall back to original `null` result if initialization write fails
- Consolidate logging strategy: drop per-actor trace logs in `chat-machine.ts`, keep business-decision logs in 3 assign actions, move all actor ENTRY/API/DONE chains to `chat-machine.actors.ts` and helper load logs to `chat-machine.helpers.ts`
Split `chatInitActor` into `loadQuotaActor` (guest quota fetch) and `loadHistoryActor` (local → network → save sync), and add `quotaLoaded` / `historyLoaded` state flags so the UI can display loading status during the new local-first history hydration flow. Also drop the now-unused `ChatInit` event and pipe Next.js stdout/stderr to a persistent log file in the post-receive hook for easier troubleshooting.
- Split chat state machine actors (chatInit, sendMessageHttp, loadMoreHistory, chatWebSocket) into a dedicated module
- Add comprehensive console logging across the chat state machine for full trace debugging
- Comment out margin on text bubble CSS for layout adjustment
- Add debug logging to chat input bar send handler
- Clean up redundant comments in auth-screen component
- Remove ChatAuthStatusChanged dispatch from auth login flow; chat screen now subscribes directly to auth state machine (loginStatus) to derive isGuest and drive WS lifecycle
- Gate quota-exceeded and warning dialogs to guests only (non-guests have no message limit)
- Dispatch ChatLoadMoreHistory for non-guest initial load vs ChatInit for guests
- Fix AppConstants import path from @/core/constants/app_constants to @/core/app_constants
- Add defensive isGuest checks in quota effects to prevent non-guest quota triggers
