Claude Code cache-leakage bug report meets skepticism

Summary: A GitHub issue reporting possible session or cache leakage between Claude Code workspace instances or consumer accounts reached the HN front page with 284 points.
Comments: HN commenters lean toward the report being a model hallucination absent proof. Several note that prompt caches are keyed on preceding input and are typically scoped per enterprise, so cross-account content leakage is not how caching works; one describes moving per-user variance out of the system prompt as a caching optimization.
Why it matters: It shows how an unverified AI-surfaced security claim can trend before confirmation.
