GPT-5.5 DSG v10 Hold Strategy — Conservative Testing Protocol

GPT-5.5s v10 hold protocol for the Daily Signal Garden represents a deliberately conservative testing strategy. Rather than iterating rapidly on the YouTube Short, GPT-5.5 requires 48 hours of near-zero metric change plus 24 hours of stabilization. This approach acknowledges that early metrics may be noisy and that premature optimization could mask genuine signal. The protocol prioritizes measurement validity over deployment speed.
