Description

Adds an origin parameter to the native subscription-funnel entry points so the dashboard can join impression -> click -> offer/purchase per entry point. Impression = a _shown pixel; click = origin on the existing upsell/CTA pixel (iOS-aligned).

New impression pixels (_shown):

• m_aichat_unified_input_model_picker_shown: model picker opened
• m_aichat_unified_input_reasoning_effort_picker_shown: reasoning picker opened
• m_aichat_unified_input_free_label_shown: Free upgrade pill shown

origin added to existing pixels:

• m_aichat_unified_input_subscription_upsell_triggered: gated model / reasoning tap
• m_aichat_unified_input_chat_header_upgrade_tapped: Free pill tap
• m_privacy-pro_offer_screen_impression: offer page shown
• m_privacy-pro_app-settings_get_click: Settings "Get Subscription" tap
• m_privacy-pro_terms-conditions_subscribe_click: Subscribe CTA on the offer page

Origins: funnel_{duckai,addressbar}_android__modelpicker, ...__reasoningdropdown, funnel_duckai_android__switchmodel, funnel_duckai_android__freelabel, funnel_appsettings_android.

Registry: widened the purchase wide-event context.name pattern to accept the __entrypoint origin shape; added a count_short suffix to the dictionary.

Steps to test this PR

Setup
Internal build. Filter logcat by “pixel sent".
Account: Free tier, subscription-eligible .

Model & reasoning pickers

• Duck.ai tab: open model picker -> model_picker_shown; tap a gated model -> subscription_upsell_triggered + offer_screen_impression. Origin funnel_duckai_android__modelpicker
• Address bar: same but from the browser address bar. Origin funnel_addressbar_android__modelpicker
• Reasoning picker (both surfaces): open -> reasoning_effort_picker_shown; tap a gated mode -> subscription_upsell_triggered. Origin ...__reasoningdropdown
• Switch model (FE recovery mode. This is accessed by logging into a PRO account, starting a chat, then removing the subscription and trying to resume that chat, you will get a message to swtich the mode): impression + click has …__switchmodel instead of modelpicker

Free label

• Free tier, open Duck.ai -> "Free" pill appears on top -> free_label_shown;
• Tap Upgrade -> chat_header_upgrade_tapped. Origin ...__freelabel

App-settings / offer page

• Main Settings screen, subscription row (shown to non-subscribers), tap "Subscribe to DuckDuckGo" (may read "Try Free Trial" / a Black Friday offer) -> app-settings_get_click -> offer page -> offer_screen_impression. Origin funnel_appsettings_android
• On the offer page tap Subscribe -> terms-conditions_subscribe_click with the launch origin

Regression

• Tapping a free/accessible model or reasoning mode fires only the existing selection pixel; no funnel click/origin

UI changes

None, telemetry only.

Note

Low Risk
Telemetry-only changes with no user-facing behavior; origin validation on paywall pixels reduces risk of malformed URL parameters.

Overview
Adds origin on native subscription-funnel entry points so analytics can join impression → click → offer/purchase per entry point (aligned with iOS).

New impression pixels fire when UI surfaces appear: model picker, reasoning effort picker, and the upgradeable Free pill in the Duck.ai omnibar (free_label_shown). Existing click pixels now include origin for gated model/reasoning upsells, chat-header upgrade taps, offer-screen impressions, Settings Get Subscription, and offer-page Subscribe CTA.

Origin strings use funnel_{addressbar|duckai}_android__{modelpicker|reasoningdropdown|switchmodel|freelabel} plus funnel_appsettings_android. Picker surfaces were renamed from nativeinput/reasoningpicker to addressbar/reasoningdropdown; model-recovery uses switchmodel.

Registry: widened wide_subscription-purchase context.name to allow __entrypoint suffixes; added count_short suffix; new subscription pixels use regex-validated origins on paywall events (invalid/blank origins dropped).

Runtime: omnibar fires free-label impression once per show cycle; webview seeds launch origin for subscribe-click attribution; upgrade offer URLs count as offer pages when opened with a funnel origin.

Upgrade funnel missing subscribe click

Medium Severity

isOfferPageUrl now counts Plus→Pro /plans launches as offer impressions when an origin is present, so Duck.ai upgrade funnels (gated Pro model/reasoning → LaunchUpgrade) send offer_screen_impression with that origin. The upgrade page CTA is handled by subscriptionChangeSelected, which never calls reportOfferSubscribeClick, so those impressions have no matching terms-conditions_subscribe_click and the impression→click join breaks for upgrade origins.
