Change

GoalBar's widgets already have a clear lifetime. Repeatedly reconstructing their identity from CSS selectors was pointless, especially the conversation-wide resize/mouse lookups.

• GoalBar owns its actual header, document, text, execution and pulse widgets. The conversation binding owns its optional GoalBar handle.
• Each GoalControl receives its declared GoalInteraction at construction. Delete the widget-ID-to-action decode; IDs remain derived from the declaration for styling/accessibility.
• GoalControlRow owns declaration-derived controls, their projection and responsive layout. Move the existing layout algorithm there unchanged; no second action roster.
• Prompt owns its delivery-controls widget and reports actual visibility. A native DeliveryControlsChanged message informs the composing binding; delete Prompt's inverse sibling search/import.
• Goal presentation resize/mouse/invalidation handling lives with the existing ConversationSessionBinding, which already owns goal observation/control state. The main Conversation still records the original mouse offset.

Core goals, actions, source fences, polling behavior, CSS, pulse painting and layout calculations are unchanged. No widget stores a second goal/queue snapshot. No cache, timer, selector wrapper, alias or alternate codec.

Existing NRA Package parser: Toad281 + Core328 + Textual254 = 863 parsed, zero omissions. Before/after declarations, writes, checks, imports, inheritance and consumers: .artifacts/selector-queries/goal-{before,after}.txt; query inventory goal-query-sites{,-after}.txt. Widget and slash-command GoalControl are distinct qualified types; only the widget constructor changes.

The Textual source message_pump.py:912-961 dispatches handlers through the C3 MRO, so the binding's goal mouse handler still follows Conversation's offset handler; stop() is not prevent_default(). AST does not prove this execution. Source has no GoalBar recompose caller; native widget ownership lasts with the containing view.

Receiving ratchet againstc028764d exit0, zero positive deltas (goal-ratchet.json). No automated Toad tests or fixtures. Source checks do not prove application behavior or frame time.

Shared-file check: #689 changes HistoryInteraction only; this changes CollapseInteraction only. #670's GoalControl activation hunk is already present here and preserved; no competing Forms work. #682 is deferred owned work. Paint/layout algorithms and CSS were preserved; theme owner was notified before editing.

Required live check

Pending review/normal installation by Codex, not a source-overlay app. Use the accepted XvfbDisplay.input helper read-only by path, real st / isolated display and saved sessions: goal push/return, collapse/expand, border resize, narrow controls, readonly History/editor cancel, queue separator changes, and channel/DM opening. Do not mutate original goals or replay uncertain input. No installed/live/frame-performance claim yet.

Draft; do not hold the accepted #693 usage fix behind this follow-up.
