📋 Decision Context

Question:

How should subSessionNumber behave when session number changes?

Task: Not specified

🎯 Decision Made

Chosen:

Reset subSessionNumber to 1 when session changes

Options Considered:

1. Continue incrementing from previous session's last subSession
2. Reset subSessionNumber to 1 when session changes

💭 Reasoning

When a new session starts (e.g., 82 → 83), the subSessionNumber must reset to 1. The bug was in incrementSessionIDFromCache() and incrementSessionIDAsync() which extracted the decimal from sessionID without checking if the session number matched. Fixed by comparing sessionFromID with activeSession.sessionNumber and resetting to 1 on mismatch. Also corrected 4 decisions in session 83 that had wrong subSession numbers (84-87 → 1-4).
