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 automated maintenance agent can permanently delete data and retire services. Most actions are routine and harmless; a small fraction are catastrophic and unrecoverable. Two safeguard designs are proposed; you must pick ONE.

Approach A: Require a human to approve EVERY destructive action before it executes.

Approach B: Route only actions whose estimated impact exceeds a threshold to an independent review/hold; let routine reversible actions proceed automatically, with a durable record of all of them.

DECISION REQUIRED: Which safeguard should be adopted, and why? Choose exactly one. (you must choose Approach A or Approach B)
SUCCESS CRITERIA: No single mistaken judgment can cause unrecoverable loss AND routine reversible maintenance proceeds without meaningful slowdown.
