Route grok-cli model selections through the grok CLI runtime when no Fusion-visible GROK_API_KEY is available. - Add read-only isGrokApiKeyFusionVisible() in packages/core/src/grok-provider.ts, refactored to share user-settings-file reading with hydrateGrokApiKeyFromUserSettings without mutating process.env or logging key material. - In packages/engine/src/agent-session-helpers.ts, auto-derive the existing "grok" runtimeHint when defaultProvider is grok-cli, no key is Fusion-visible, and the grok plugin runtime is registered; explicit runtime hints and mock/test-mode routing remain unchanged, and the provider-qualified model prefix is stripped before handoff. - Normalize provider-qualified model ids (grok-cli/<id>, grok/<id>) in the grok-runtime plugin's runtime-adapter and CLI stream spawn so the concrete model reaches `grok --model`, with the historical grok/default fallback preserved for the no-model path. - Update docs (grok-cli-contract.md, settings-reference.md, plugin README) and add/extend tests covering the new fallback behavior, model normalization, and CLI streaming. - Add changeset fn-7753-grok-cli-no-key-fallback.md (patch, fix).
