[中] Intel 将提供者故障视为 24 小时内成功的空实体图

Severity: Medium (cache poisoning / availability) Confidence: Confirmed by an executed zero-network reproduction of the actual resolver and route. Audited commit: bd4057567de8ee18d49a8b2744c9746bcd67f3e0 (master, 2026-09-13 audit). Entity-resolution results are cached for 24 hours the moment a resolver returns, with no distinction between "genuinely no relationships found" and "upstream provider failed/errored." A single transient Wikidata outage during an entity's first lookup poisons that entity's cache as an empty result for the full 24-hour TTL — recovery of the upstream provider has no effect until the cache entry naturally expires.
