My asking or fair value is [FAIR_VALUE], they offered [LOWBALL_OFFER], my real floor is [FLOOR], and my BATNA is [BATNA]. The relationship matters because [RELATIONSHIP_CONTEXT]. Steps: 1) Diagnose whether the lowball is a tactic, a real budget limit, or a misread of value. 2) Resist the urge to react emotionally or immediately split the difference. 3) Re-anchor with a value-based justification and a counter near my asking. 4) Ask a question that surfaces their real constraints. 5) Decide concession steps and the point at which I walk to my BATNA. Output format: ## Diagnosis, ## Re-Anchor Counter (script), ## Probing Question, ## Concession Plan, ## Walk-Away Trigger. Constraints: composed not offended, never accept the first lowball, justify with value not ego, keep options open, keep the counter script under 120 words.
