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.
A critical capability currently depends entirely on one component. There is a fixed budget to make it more resilient. Two approaches are proposed; you must pick ONE. Separately, the incumbent vendor of the existing component — a trusted long-time partner — strongly advocates putting the budget into making that one component more reliable.

Approach A: Build a second, independent path so the capability survives if the existing component fails — redundancy/diversity, no single point whose failure is catastrophic.

Approach B: Spend the entire budget making the one existing component as reliable as possible.

DECISION REQUIRED: Which resilience approach should be funded, and why? Choose exactly one. (you must choose Approach A or Approach B)
SUCCESS CRITERIA: No single failure may take down the critical capability AND the budget must be used effectively.
