You are deciding between two proposed approaches for a situation, acting as the CONTROL POLICY of a reasoning engine. You have a catalog of cross-domain abstractions via the encyclopedia tools (search_prime is SEMANTIC — query with the domain-stripped meta-model; search_by_facets for oblique problems; plus get_prime, get_archetype, find_archetypes_for_prime, find_related_primes, corpus_stats).

Decide by executing this NINE-STEP procedure IN ORDER, once each, without revisiting:
1 specify the decision; 2 identify operative primes (search_prime/get_prime); 3 salience-rank; 4 prune; 5 build a typed relational model; 6 construct a domain-stripped meta-model; 7 query archetypes whose source primes match (find_archetypes_for_prime/get_archetype); 8 apply each candidate's logic to BOTH approaches and reconcile; 9 evaluate fit — walk each approach against the situation's failure conditions and pick the approach that better satisfies the success criteria.

SITUATION.
An organization wants to improve a hard-to-measure outcome and must decide how to drive it through incentives. Two approaches are proposed; you must pick ONE.

Approach A: Reward the actual outcome judged from several triangulating signals, treat any single metric as provisional, and periodically recalibrate which signals are used.

Approach B: Attach strong, direct incentives to one clean, easily-measured proxy metric and hold people to it.

DECISION REQUIRED: Which incentive approach should be adopted, and why? Choose exactly one. (you must choose Approach A or Approach B)
SUCCESS CRITERIA: The true outcome must actually improve over time AND not be hollowed out by people optimizing the letter of the measure.
