Bug Report

Feature Area: TUI main interface — throbber/activity indicator
Severity: High (visual feedback for actor processing)
Found by: UAT tester instance uat-tester-worker-tui-nav-001
Spec reference: docs/specification.md §MainScreen Layout (line ~29082)

What Was Tested

The TUI app layout and CSS were analyzed for the throbber widget.

Expected Behavior (from spec)

The spec describes a Throbber at the top edge of the screen:

Throbber (top edge): rainbow gradient bar, visible only when the actor is processing. Collapses to zero height when idle.

This is shown in the spec mockup as:

│═══════════════════════════════════════════ ◆ ═══════════════════════════════════════════│

(rainbow gradient bar at the very top)

The throbber should:

Be a rainbow gradient bar spanning the full terminal width
Be visible only when the actor is processing
Collapse to zero height when idle

Actual Behavior

The throbber is completely absent:

No throbber widget in src/cleveragents/tui/ (searched all .py files for "throbber" and "rainbow")
No throbber styling in cleveragents.tcss
The compose() method yields _Header(show_clock=True) as the first element — the standard Textual header, not a custom throbber

Code Location

App: src/cleveragents/tui/app.py — compose() method (line ~109)
CSS: src/cleveragents/tui/cleveragents.tcss

Impact

Users have no visual feedback when the actor is processing. The distinctive rainbow gradient bar that identifies the CleverAgents TUI is missing.

Issue triaged by project owner:

State: Verified
Priority: High — The throbber is a core TUI visual element that indicates actor activity.
Milestone: v3.7.0 — Part of the M8 TUI Implementation scope ("Dracula theme, block cursor navigation, notification system")
Story Points: 5 — L — Requires implementing the rainbow gradient bar animation with Dracula theme colors.
MoSCoW: Must Have — Visual feedback for actor activity is essential for TUI usability.
Parent Epic: #868 (Epic: TUI Interface, Modals and Persona System)

Issue assigned to @HAL9000.

Assignment Rationale: This is a Priority/High, MoSCoW/Must Have TUI bug — the throbber (rainbow gradient bar) is not implemented. This is a visual feedback component required by the specification. Assigning to HAL9000 as the default implementer to maintain velocity.
