Deep vendor compatibility snapshot

Evidence Atlas

The complete 2026-08-28 research seed, published at its original vendor → product → exact-surface → atomic-feature resolution. The Atlas is broader than the curated web/desktop/CLI matrix and keeps adapters, IDE modes, cloud agents, protocol roles, and mobile surfaces distinct.

Documentation-backed, not independently certified.Registry membership proves only the role or portable components the registry lists. First-party documentation establishes a dated documented claim. No runtime conformance suite was executed, and unknown never means unsupported.
