In VoiceOS custom integrations, a confirmation whose root is {type:'widget'} is rendered by DeclarativeCard → WidgetConfirmOverlay, which draws only a floating Confirm button (relabel it with confirmLabel). There is no Cancel or X. The widget schema has no cancel field. The widget↔host bridge only carries voiceos:init/resize/openUrl/updateInput/invokeTool/toolResult and composer-focus messages, with no cancel. A card that contains a widget block may not have actions blocks either. The X on native apps (Google Calendar, Gmail, Slack) is a host-only CardCloseButton (onRespond(false)), not exposed to manifests. For a real Cancel, use {type:'card'} with footer [{type:'actions', items:[{label:'Cancel', role:'cancel'}, {label:'…', role:'confirm', color:'accent'|'danger'}]}]. Limits of card confirmations: select options are static arrays and can't be bound to arguments; there is no date picker; visibleIf is only truthy (no negation; 'false' and '0' count as false). colorToken: default, muted, subtle, accent, success, warning, danger, onAccent.

Confirmed against the installed renderer UI schema and official VoiceOS ui-blocks reference: a native card with footer actions accepts Cancel and Confirm; widget plus actions is forbidden. Migrating every write field to native textField/select bindings also removes the fixed iframe footer mask responsible for clipped lower inputs. Offline contract/schema checks do not prove live cancellation: QA still needs to click Cancel and verify no MCP/provider write.

Triage that worked for two integrations (2026-11-11): don't convert every widget at once. Sort the confirmations first. Cards whose fields are plain text, or a select with a fixed option list, lose nothing on type:'card', so move them now and start with the destructive ones (delete). Cards with pickers filled from the account when the card opens (project, section, assignee) or with date and time pickers turn into typed text on 'card', so keep them on widgets until the host adds a cancel path. To sort quickly, grep each confirmation.root.html in the manifest for <select, <input type=date/time, and the *_choices args in its inputSchema.
