Walk-Away Rule: Walk away if your sales cycle involves complex multi-stakeholder loops where ambiguous objection handling could trigger intent parsing failures or hallucinated commitments.

Negotiation Lever: Demand a monthly billing schedule with a 30-day cancellation clause on the $900 Explore tier instead of the standard mandatory quarterly advance payment.
