What
Claude Code now records, per artifact, whether its sandbox (an isolated execution environment) has network egress (outbound network access) disabled or not. This setting is cached, but after a set age it's treated as unknown rather than trusted, so it must be re-checked.
Why
Caching the setting avoids repeatedly re-checking it, while the staleness cutoff makes sure Claude Code doesn't act on a network-access setting that may no longer be accurate.
