   Triage

   Thanks for the thorough surface-by-surface table, @vitalyiegorov!

   What I found

   • On current main (unchanged since a1d9d72), the composer, model sheet, and subagent bar still render ProviderIcon. This is separate from [Bug]: Switching accounts mid-thread shows the handoff as "Claude Opus 5.5 → Claude Opus 5.5" #15476/fix(clients): handoffs between accounts show which account is on each side #15477 and from fix(mobile): account badges no longer clip wide initials like WO #15908.
   • Composer: ThreadComposer and NewTaskDraftScreen pass ProviderIcon into the model control, and the label is the model name, so two Claude accounts look identical. Web's ProviderModelPicker uses ProviderInstanceIcon with shouldShowInstanceBadge.
   • Subagent bar: mobile ProviderSubagentBar only receives { driver, iconUrl }. Web's bar gets the instance entry and showInstanceBadge from ChatView.
   • Model sheet header: ThreadSettingsSheet is a bare glyph, and providerDisplayLabel in apps/mobile/src/lib/modelOptions.ts returns displayName whenever it's set, so two instances named "Claude" stay indistinguishable. Web's ModelPickerSidebar badges and names the instance with resolveProviderInstanceDisplayName.
   • A few of the cited spots follow a different treatment on web too:
     • SubagentRow already prefixes resolveProviderInstanceDisplayName. Web's subagent tooltip adds the account name when shouldShowInstanceBadge is true.
     • Web's SubagentAvatar (V2LifecycleRow.tsx) is also a bare glyph, like mobile's in thread-subagent-group.tsx.
     • The web environment provider list only badges when an accent color is set (ProviderInstanceCard, showBadge={Boolean(accentColor)}). Mobile's SettingsEnvironmentDetailRouteScreen never badges.
   • ProviderInstanceIcon draws the glyph at 60% opacity even when showBadge is false, which is worth keeping in mind when swapping it in.

   Likely fix area

   • Switching the composer, new-task draft, model sheet header, and subagent bar to ProviderInstanceIcon with shouldShowInstanceBadge, and passing the instance entry into mobile ProviderSubagentBar.
   • Optionally using resolveProviderInstanceDisplayName for the model sheet header to match web.
   • Whether the subagent avatar and environment list should match web's narrower rules or badge everywhere is a separate choice. fix(mobile): account badges no longer clip wide initials like WO #15908's layout fix would carry over automatically once these use the shared component.

   A maintainer will decide on the fix direction.

   PR opened: #15922. The composer and new-task draft draw the account badge using the shared shouldShowInstanceBadge rule and ProviderInstanceIcon. Before and after screenshots of the same thread are in the PR.
