📋 Decision Context

Question:

How to fix reconnectCount starting at 1 instead of 0 for new agents?

Task: Phase 0 - Immediate fixes for Session 92

🎯 Decision Made

Chosen:

Check if agent exists before upsert; only $inc reconnectCount for existing agents, use $setOnInsert: { reconnectCount: 0 } for new ones

Options Considered:

• No alternatives documented

💭 Reasoning

MongoDB $inc on upsert initializes missing fields to 0 then adds, so reconnectCount always started at 1. By checking existence first and conditionally adding $inc, new agents correctly start at 0 and existing agents increment.
