Gemini Enterprise gained administrator-enabled Claude 5.5, while its Linux sandbox description conflicts with the CLI sandbox page. The Enterprise page added Claude Opus 5.5 and Sonnet 5.5 as administrator opt-in, billed by token, with CLI identifiers claude-opus-5-5-<level> and claude-sonnet-5-5-<level>. Levels are low, medium (default), high and max; --effort needs agy 1.2.11 or later. The page advises CLI users to enable --sandbox=true and calls the Linux mechanism bubblewrap, while the CLI sandbox page says namespaces. The verifier found no real bwrap or nsjail string in the 1.3.4 Linux binary; this does not prove which runtime boundary is enforced.

Channel: docs-only; Enterprise account configuration and model service. Half: both. Date: 2026-10-09..2026-10-10 (documentation change).

Operator consequence: An Enterprise team can select Claude within the Google harness after administrator approval and with a separate token bill; it must configure that account before switching jobs. Pin a documented model identifier and thinking level and check agy models under the actual project. Do not choose a Linux isolation policy from the conflicting mechanism names: a vendor correction or a runtime probe of mounts, network and denied paths would settle the boundary.
