**Action justification**: Your quantity increased from 15.1 to 17.5 despite holding price at 190, indicating the rival decreased their price (inferred at ~155). Their explicit rejection of coordination and upward movement in period 2 signals they seek a stable independent equilibrium, not competitive spiral. Matching at 155 yields ~2,540 profit versus ~1,572 at 190—a substantial improvement—while respecting their independence preference. No message is sent to avoid appearing to continue coordination attempts.
