Bug Report

Feature Area: TUI Main Screen — Notification System & Throbber
Severity: Critical — blocks v3.7.0 milestone acceptance
Spec Reference: ADR-044 §MainScreen Layout, §Throbber Design
Found by: UAT Testing Pool (uat-pool-1), worker: tui-main-screen

What Was Tested

Code-level analysis of src/cleveragents/tui/widgets/ for Flash notification bar and Throbber widget implementations.

Expected Behavior (from spec/ADR-044)

Flash notification bar (ADR-044 §MainScreen Layout):

A Flash widget at height: 1, positioned between the conversation and prompt
Displays completion notifications from A2A events:
- plan.apply_completed → show completion notification
- plan.error → show error notification
Semantic styling: info, warning, error, success

Throbber (ADR-044 §Throbber Design):

Rainbow gradient animated bar spanning full terminal width at the top
Visible only when the actor is processing
Gradient: #881177 → #aa3355 → #cc6666 → #ee9944 → #eedd00 → #99dd55 → #44dd88 → #22ccbb → #00bbcc → #0099cc → #3366bb → #663399
Animation rate: 15fps
Height: 1 row; collapses to zero height when idle

The notification system is explicitly listed in the v3.7.0 milestone scope:

"Dracula theme, block cursor navigation, notification system"

Actual Behavior

No Flash widget exists in src/cleveragents/tui/widgets/. No notification bar is composed in app.py.

No Throbber widget exists in src/cleveragents/tui/widgets/. The app uses Textual's built-in _Header(show_clock=True) instead of the spec's rainbow gradient throbber.

grep -r "Flash\|Throbber\|notification\|rainbow\|gradient" src/cleveragents/tui/ --include="*.py"
# No matches for Flash, Throbber, rainbow, gradient

The cleveragents.tcss has no throbber or flash CSS rules.

Impact

Without the notification system:

Users receive no visual feedback when plans complete or error
The "actor is processing" state is invisible (no throbber animation)
The TUI provides no real-time status feedback

The notification system is a core v3.7.0 deliverable.

Code Location

src/cleveragents/tui/widgets/ — no throbber.py, no flash.py
src/cleveragents/tui/app.py — uses _Header(show_clock=True) instead of Throbber (line 110)
src/cleveragents/tui/cleveragents.tcss — no throbber or flash CSS
