/**
 * Change-set escalation — Layer 2 of the replacement oracle (drift-remediation
 * plan § 2, [G4]). Runs the review-only change-set probe ONLY on rows whose
 * Layer-1 verdict is `conditional`/`may` on a stateful or pinned-name
 * resource: definite createOnly hits are already proven, and stateless
 * unpinned conditionals never ticket, so probing either buys no proof. A
 * non-engaged deploy issues zero probe calls.
 *
 * Verdict precedence: change-set > registry > cdk-spec.
 *   Replacement: False       → the ceremony DOWNGRADES to a warning — the row
 *                               becomes an in-place update (directive 2:
 *                               never block on a false positive)
 *   Replacement: True        → conditional upgrades to definite, verdictSource
 *                               `"change-set"`
 *   Replacement: Conditional → stays worst-case (the registry verdict stands)
 *   probe failure            → the registry verdict stands, annotated
 *                               `"registry (change-set unverified)"` — degrade
 *                               to the conservative verdict, never to silence
 *
 * A resource the change set omits entirely (including the benign
 * `didn't contain changes` outcome) will not be touched by the update —
 * treated as `False`.
