# Invariant 6 — Plane Isolation A failure in any plane cannot: * halt withdrawals * corrupt NAV * modify supply * degrade other planes’ executions * influence valuations outside its own scope Instead: * failed plane becomes paused * its value is excluded * vault operates with surviving planes * users can withdraw from zkSync reserves, then via unwind of healthy planes This prevents cascading failure. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://multistake-1.gitbook.io/multistake-docs/documentation/cross-domain-invariants/differing-invariants/invariant-6-plane-isolation.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
