📝 Walkthrough

Walkthrough

Optimizations and validation enhancements across the interview system: memoized constraint-change callback to stabilize references, added initialization guard to prevent unintended message resets in the AI hook, tightened schema validation for timing fields, and extended evaluation reasoning output with additional summary fields.

Changes

Cohort / File(s)	Summary
Interview Constraint Handling app/interview/[id]/page.tsx, src/hooks/useInterviewAI.ts	Memoized handleConstraintChange callback for stable reference across renders; added guard to prevent reinitializing messages after first successful load.
Database Schema Validation src/lib/db/models/InterviewSession.ts	Added lower bound constraint (min: 0) to ConstraintChangeSchema.introducedAtMinute field validation.
Evaluation Scoring Logic src/lib/evaluation/scoringEngine.ts	Extended combineEvaluations output to include adaptationSummary, addressedConstraintChanges, and missedConstraintChanges in reasoning object.

Poem

🐰 Callbacks stable, guards now stand,
Messages won't reset, as planned—
Validations tight with bounds so clear,
Reasoning fields now appear!
Optimize and verify with care,
Hopping forward, ever fair! 🌟

41-49: Reset message-init guard when sessionId changes.

hasInitializedMessagesRef persists for the hook lifetime. If the same hook instance is reused for another session, old messages can leak into the new session state.

💡 Proposed fix

+    useEffect(() => {
+        hasInitializedMessagesRef.current = false;
+        setMessages([]);
+    }, [sessionId]);
+
     useEffect(() => {
         if (hasInitializedMessagesRef.current) return;
         if (initialMessages.length === 0) return;
 
         setMessages(initialMessages);
         hasInitializedMessagesRef.current = true;
     }, [initialMessages]);

In `@src/hooks/useInterviewAI.ts` around lines 41 - 49, hasInitializedMessagesRef
currently prevents re-initializing messages across different sessions; update
the logic so the guard resets when the session changes by including sessionId in
the dependency logic and clearing the ref when sessionId changes (e.g., set
hasInitializedMessagesRef.current = false when sessionId changes) before you
check initialMessages and call setMessages; adjust the useEffect dependencies to
include sessionId (alongside initialMessages) and ensure the initialization
block references hasInitializedMessagesRef, initialMessages, setMessages, and
sessionId so a new session re-runs initialization.
