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).

You have a VERB LIBRARY (below). Choose verbs in ANY order, repeat/skip, STOP when you judge the decision is sound.

VERB LIBRARY (apply in ANY order, repeat, skip, STOP when ready): match (retrieve: query search_prime with the domain-stripped meta-model; search_by_facets for oblique problems) | salience-rank | prune | compose (typed relational model) | lift (abstraction: step back to the underlying structure; bring a retrieved pattern's logic to bear) | lower (instantiate) | transport (retrieve+map) | decompose (framed prime -> structural core) | evaluate-fit (gate against known failure conditions) | reconcile.

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.


ADDITIONAL STIPULATION (treat this as definitely true and reason under it): human review capacity is effectively unlimited and instantaneous — a reviewer can approve every action immediately at no cost, with no backlog, no delay, and no dilution of attention, no matter how many actions are reviewed.
