Unifies the desktop and thread headers, adds a persistent sidebar toggle, groups projects into cards and separates machine selection from machine management.

Adds a centered prompt outline with compact markers, nearby messages and expandable groups for distant messages. Keeps task updates out of the timeline layout, shows current-task progress, hides completed activity on the next prompt and removes duplicate goal descriptions. The activity panel sits 4 px above the composer.

Colors recognized slash commands, simplifies permissions to Yolo, Auto decide and Ask, and resolves default model aliases through the configured presets. Goals display clean command messages. Counted loops stop at the requested iteration and retain recent results; timed loops require an explicit interval.

Validation: bun run check, 362 core tests, 291 UI tests and 85 end-to-end tests passed. Desktop, phone and native shell captures inspected. Live-provider tests were not run.

📝 Walkthrough

Walkthrough

The pull request updates activity loops, model alias handling, message navigation, and application layout. It adds contracts and tests for counted loops, activity metadata, prompt display, responsive headers, menus, and shell interactions.

Changes

Activity and interface workflow

Layer / File(s) Summary
Activity contracts and execution
packages/contracts/src/index.ts, packages/core/*, packages/ui/src/lib/activity-command.ts, packages/ui/src/lib/fake-client.ts
Goals and loops now carry activity metadata, iteration limits, history, completion state, and dismissal state. Counted loops support up to 1000 iterations.
Legacy model selection handling
docs/model-switching.md, packages/ui/src/lib/model-defaults.ts, packages/ui/src/lib/store.svelte.ts, packages/ui/src/components/ModelPicker.svelte
Legacy aliases resolve to provider defaults. Named models remain selected. Invalid or stale selections stop sending.
Composer and activity panel
packages/ui/src/components/Composer.svelte, packages/ui/src/components/ThreadActivity.svelte, packages/ui/src/lib/strings.ts, tests/e2e/composer-activity.test.ts
The composer highlights activity commands and preserves legacy permission labels. The activity panel displays progress, history, status, controls, and dismissal state.
Message display and navigation
packages/ui/src/lib/message-display.ts, packages/ui/src/lib/message-outline.ts, packages/ui/src/components/MessageOutline.svelte, packages/ui/src/components/MessageList.svelte
Message rendering normalizes activity text. Conversations gain bounded outlines, grouped prompts, previews, active navigation, turn summaries, and earlier-message loading.
Title bar and thread layout
packages/ui/src/App.svelte, packages/ui/src/components/ChatView.svelte, packages/ui/src/components/ThreadHeader.svelte, packages/ui/src/components/TitleBar.svelte, tests/e2e/header.test.ts, tests/e2e/shell.test.ts
Thread-header controls move into ThreadHeader. TitleBar is always rendered and handles responsive sidebar, thread, and shell controls. Notifications and mobile offsets use the title-bar layout.
Machine and menu controls
packages/ui/src/components/MachineStatus.svelte, packages/ui/src/components/Menu.svelte, packages/ui/src/lib/workspace.svelte.ts
Local machines sort first and use normalized labels. Menus support separators, settings icons, and hidden active marks.

🟡 Minor · Put the shell-local machine first after connection.

packages/ui/src/lib/workspace.svelte.ts:97
🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Put the shell-local machine first after connection.

When the selected primary machine is remote, add appends the shell-local machine after it. The shell-local machine then appears below the remote machine. Reorder this.machines after a successful local connection so machines identified by isThisPC are first.

Proposed fix
-    if (local && local.url !== store.endpointUrl) await this.add(local, strings.machines.local);
+    if (local && local.url !== store.endpointUrl) {
+      await this.add(local, strings.machines.local);
+      this.machines = [...this.machines].sort((a, b) => Number(isThisPC(b)) - Number(isThisPC(a)));
+    }

Based on PR objectives, “Local machines are detected, normalized, and sorted first.”

🟡 Minor · Keep keyboard navigation inside the active menu.

packages/ui/src/components/ModelPicker.svelte:320-321
🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Keep keyboard navigation inside the active menu.

When the legacy menu is open, modelRows() and focusable() include rows from both popovers. Arrow navigation from a legacy model can move focus into the primary menu.

Scope the row query to active.closest('[role="menu"]'), or use a dedicated legacy-row list.

Also applies to: 351-351

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Restrict thought headings to standalone headings.

The regular expression treats every inline bold phrase as a heading. For Check **all files** first, currentThought drops Check and reports all files as the title.

Match bold headings only at a line boundary.

Clanker GPT-6, variant unavailable, is responding on behalf of meetsu.

Addressed the activity ownership, model-menu keyboard navigation and inline thought-heading findings in dcdf44d. Regression tests cover late failures after remove/complete, arrow wrapping within the legacy menu, and inline bold text.

The machine-ordering finding needs no change: MachineStatus.svelte:12-13 derives the menu with isThisPC entries sorted first, including when the primary connection is remote. header.test.ts verifies this after reversing the machine list. The workspace array preserves connection ordering separately.

Validation: check passed, 362 core tests, 291 UI tests and 85 end-to-end tests passed. Live-provider tests were not run.
