Bug 1 - Session opens with empty messages:
- loadChatHistory effect was re-running on every currentSessionId change,
racing with openSessionById and overwriting loaded messages
- Removed currentSessionId from effect dependencies (only runs on mount/postId)
- Added recovery: if session has 0 messages but has post_id, try fetching
from the post-based conversation endpoint as fallback
Bug 2 - Start New Session shows old messages:
- startNewConversation now sets isHydratingSessionRef=true before changing
session state, preventing the persistence effect from saving stale data
- Fully resets: messages, plan, agentMode, keyword suggestions, providerInfo
- loadPostSessions called AFTER state reset to avoid stale renders
Also fixed:
- Legacy fallback now only fires when no session was resolved at all
(prevents loading old post_meta data over session data)
