 `Button` now completes the legacy `.btn` / `.btn-*` migration inventory: the remaining worktree summary/manage flows now use the shared primitive from the public UI barrel, and the previous bounded migrations across auth, config actions, supervisor dialogs, git flows, file-tree dialogs, notifications, and shared mobile/desktop shells leave no feature-local raw `.btn` callsites behind. Legacy compatibility classes remain emitted by the shared primitive for zero-regression styling while ownership stays in the component.
 
-`IconButton` now covers a broader bounded icon-action slice: the desktop topbar add/settings/files/terminal triggers, the shared workspace fullscreen control, the mobile topbar more-actions/fullscreen triggers, the supervisor card edit/pause-resume/trigger/disable controls, the git-panel row stage/unstage/discard actions, the file-tree search/tree-row create-delete actions, the git-status-bar fetch action, the code-editor mobile toggle plus editor/diff close controls, the shared toast dismiss control, the desktop workspace-launch close control, the mobile workspace-drawer close action, the mobile-select trailing side actions, and the agent session-card / draft-launcher header controls all use the shared primitive from the public UI barrel while preserving caller-owned compatibility classes such as `topbar-add`, `topbar-btn*`, `mobile-topbar__icon-button`, `supervisor-icon-btn*`, `git-row-action`, `git-status-bar__item*`, `code-mode-btn`, `mobile-sheet__action--icon`, `toast__close`, `launch-close-btn`, `mobile-workspace-drawer__item-close`, `mobile-select-sheet__item-side-action*`, and `session-action-btn*`. Broader deferred icon-action families remain intentionally outside this slice.
+`IconButton` now completes the feature-layer raw icon-only action-trigger inventory. The remaining desktop/mobile topbar icon-only triggers, shared workspace fullscreen control, supervisor card actions, git/file-tree/status-row actions, code-editor and git-diff close chrome, modal/dialog and toast close controls, mobile-select trailing side actions, terminal/workspace tab and selector close controls, shortcut reset, mobile workspace drawer close, and workspace file-toolbar actions all use the shared primitive from the public UI barrel while preserving caller-owned compatibility classes such as `topbar-add`, `topbar-btn*`, `mobile-topbar__icon-button`, `supervisor-icon-btn*`, `git-row-action`, `git-status-bar__item*`, `code-mode-btn`, `mobile-sheet__action--icon`, `toast__close`, `launch-close-btn`, `mobile-workspace-drawer__item-close`, `mobile-select-sheet__item-side-action*`, `session-action-btn*`, `topbar-close`, `terminal-tab-close`, and `terminal-selector-item-close`. The remaining raw feature buttons audited on this pass are intentionally not counted on this row because they are text-bearing buttons, tabs/selectors, counters, backdrops, or other specialized controls rather than icon-only action triggers.
 
 `Textarea` now completes the bounded legacy `.input.textarea` migration inventory: the provider startup-args textarea and the supervisor objective textarea both use the shared primitive from the public UI barrel while preserving legacy `input` / `textarea` compatibility classes and caller-owned hooks such as `settings-provider-args-input`. The primitive also supports optional auto-resize for later adopters. The `git-panel` commit message field is intentionally not counted on this row because it is not part of the `.input.textarea` family selected for this slice, and standalone `.textarea` utility usage remains outside this row.
