Track Specification: Manual Ticket Queue Management (ticket_queue_mgmt_20260306)

Overview

Allow user to manually reorder, prioritize, or requeue tickets in the DAG. Add drag-drop reordering, priority tags, and bulk selection for execute/skip/block operations.

Current State Audit

Already Implemented (DO NOT re-implement)

Ticket Model (src/models.py)

• Ticket dataclass: Has status, depends_on, but no priority field
• mark_blocked(reason): Sets status to blocked with reason
• mark_complete(): Sets status to completed

DAG Engine (src/dag_engine.py)

• TrackDAG: Manages ticket dependency graph
• get_ready_tasks(): Returns tasks with satisfied dependencies
• update_task_status(): Updates ticket status
• has_cycle(): Validates DAG

Gaps to Fill (This Track's Scope)

• No priority field on Ticket
• No drag-drop reordering in GUI
• No multi-select for bulk operations
• No bulk execute/skip/block actions

Architectural Constraints

DAG Validity

• Reordering MUST NOT violate dependencies
• Cannot move ticket before its dependencies
• depends_on relationships preserved

Atomic Operations

• Bulk operations apply to all selected tickets atomically
• Partial failure rolls back all changes

Architecture Reference

Key Integration Points

File	Lines	Purpose
src/models.py	30-50	Ticket - add priority field
src/gui_2.py	2650-2750	Ticket display - add drag-drop
src/dag_engine.py	50-80	Status updates

Proposed Ticket Enhancement

@dataclass
class Ticket:
 # ... existing fields ...
 priority: str = "medium"  # "high" | "medium" | "low"

Functional Requirements

FR1: Priority Field

• Add priority: str = "medium" to Ticket dataclass
• Values: "high", "medium", "low"
• Persist in track state

FR2: Priority UI

• Dropdown or button group per ticket
• Color-coded: high=red, medium=yellow, low=gray
• Save to state on change

FR3: Drag-Drop Reordering

• Drag ticket to reorder in list
• Drop validates DAG (no dependency violation)
• Show error if invalid position

FR4: Multi-Select

• Checkbox per ticket for selection
• Select all / deselect all buttons
• Track selected ticket IDs

FR5: Bulk Actions

• Execute: Mark all selected as ready
• Skip: Mark all selected as completed
• Block: Mark all selected as blocked

Non-Functional Requirements

Requirement	Constraint
Response Time	<100ms for drag-drop validation
Persistence	Priority saved to state.toml

Testing Requirements

Unit Tests

• Test priority field serialization
• Test DAG validation on reorder

Integration Tests

• Drag-drop tickets, verify order changes
• Bulk block tickets, verify all blocked

Out of Scope

• Automatic priority assignment
• Priority-based auto-scheduling
• Cross-track ticket movement

Acceptance Criteria

• Priority field added to Ticket
• Priority dropdown works in UI
• Drag-drop reordering functional
• DAG validity enforced on drop
• Multi-select with checkboxes
• Bulk execute/skip/block works
• 1-space indentation maintained
