-# Track Specification: Track Progress Visualization
+# Track Specification: Track Progress Visualization (track_progress_viz_20260306)
 
 ## Overview
-Progress bars and completion percentage for tracks/tickets.
+Progress bars and percentage completion for active tracks and tickets. Better visualization of DAG execution state.
 
-## Current State Audit
-### Already Implemented
-- Track/ticket status tracking
-- DAG execution state
-
-### Gaps to Fill
-- No progress bars
-- No completion %
-
-## Goals
-- Visual progress bars
-- % completion
-- Time estimates
+## Architectural Constraints
+- **Accurate State**: Progress MUST reflect actual ticket status.
+- **Efficient Updates**: Status changes MUST trigger efficient UI updates.
 
 ## Functional Requirements
-- Progress calculation
-- Bar rendering
-- ETA estimation
+- **Progress Bar**: Visual bar showing % complete.
+- **Percentage Text**: Display numeric % completion.
+- **Ticket Breakdown**: Show completed/remaining counts.
+- **ETA Estimate**: Calculate approximate completion time.
 
-## Non-Functional Requirements
-- Accurate state sync
+## Acceptance Criteria
+- [ ] Progress bar renders.
+- [ ] Percentage accurate.
+- [ ] Counts match actual tickets.
+- [ ] ETA calculation works.
+- [ ] Updates reflect state changes.
