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.
