Bug Report

Feature Area: TUI Throbber / Activity Indicator
Severity: Medium (backlog)
Found by: UAT tester instance uat-tui-worker-1
Spec reference: docs/specification.md §Throbber (lines ~29745–29758)

What Was Tested

The src/cleveragents/tui/app.py was inspected for throbber implementation.

Expected Behavior (from spec)

The spec defines a rainbow gradient animated bar at the top of the TUI:

┌───────────────────────────────────────────────────────────────────────────┐
│ ════════════════════════════════════ ◆ ═══════════════════════════════════│
│ (actor processing...)                                                     │
│                                                                           │
│ (idle — throbber collapses to zero height)                                │
└───────────────────────────────────────────────────────────────────────────┘

The gradient cycles through 12 colors at 15fps:
#881177 → #aa3355 → #cc6666 → #ee9944 → #eedd00 → #99dd55 → #44dd88 → #22ccbb → #00bbcc → #0099cc → #3366bb → #663399

Key behaviors:

Visible only when the actor is processing — collapses to zero height when idle
Spans the full terminal width at the top edge
Controlled by ui.throbber setting: rainbow (default) or quotes (rotating text quotes)

Actual Behavior

The _TextualCleverAgentsTuiApp.compose() yields:

_Header(show_clock=True)  # Standard Textual header, not a throbber
_Vertical(id="main-column"):
    ...
_Footer()

There is no throbber widget. The _Header is a standard Textual header with a clock, not the spec-required rainbow gradient bar. There is no animation, no collapse-to-zero-height behavior, and no 15fps color cycling.

Code Location

App: src/cleveragents/tui/app.py — compose() (line ~109)
Missing: ThrobberWidget class with rainbow gradient animation
Missing: 15fps timer to cycle gradient colors
Missing: Show/hide logic tied to actor processing state

Impact

Users have no visual indication that the actor is processing
The distinctive rainbow gradient that identifies the CleverAgents TUI is absent
The ui.throbber setting has no effect
