  • EntryPoint: Enumerates entry points to Gemini (AI Hub, Omnibox Summarize, Context Menu text selections, Onboarding chips).
  • InputType: Tracks different submission formats (text, summarize page, related sites, suggested replies).
  • FloatyUpdateSource: Triggers for hiding/showing the floating bubble (scroll event, keyboard appearance, page navigation).

2. Startup Results

• gemini_entry_flow_result.h: Declares the GeminiEntryFlowResult enum representing outcomes of starting the Gemini flow (Success, Cancelled, AccountIneligibleByEnterprise, AccountIneligibleByGemini, or Unknown).

3. Conditional Feature Eligibility

• gemini_feature_availability.h & gemini_feature_availability.mm: Provides logic to verify whether sub-features (such as kImageRemix / Image Editing) are available for a specific user profile, identity manager, or AccountInfo capability set, providing control beyond simple static Feature Flags.

4. User Preferences & Policies

• gemini_prefs.h & gemini_prefs.mm: Encapsulates calls to PrefService to manage states:
  • Enterprise policies governing GenAI and Gemini enablement.
  • Onboarding consent states and tracking whether a user has already seen the Promo.
  • Resetting consent preferences.
