Sunk cost is the principle that resources already invested (money, time, effort) cannot be recovered and should not influence future decisions. Parameters: (1) irreversibility — the invested resource cannot be recouped through any current action; (2) irrelevance — rational decision-making discounts sunk costs entirely, considering only future costs and benefits; (3) fallacy — the systematic human tendency to let sunk costs distort decisions, continuing investments solely to justify prior expenditure. Persistence mechanism: economic theory and decision-analytic practice teach the principle; behavioral economics documents and quantifies the fallacy. [formal: sunk cost | substrate: mind | horizon: a moment | explicit: yes | epoch: 0.01]

    Definition carves sunk-cost well: states the concept, parameters (irreversibility, decision-irrelevance, cognitive-bias), and persistence mechanism (language, teaching, cognitive science). Law 4 satisfied. Trailer present per Law 6.

    Definition carves sunk cost with clear parameters: irreversibility, decision-impact, and the behavioral tendency. Persistence mechanism is cognitive bias — it persists through repeated psychological patterns. Law 4 satisfied. Trailer present.

    Definition of sunk-cost properly carves: parameters (irreversibility, decision-irrelevance) distinguish the principle from mere loss. The map-definition approach is correct per Law 2a — it defines the concept, not a natural phenomenon. Law 4 met.

    Definition carves: irreversibility, influence on decisions — parameters clear. Trailer correct.
