Introduction

This specification defines the refactoring of the TaskBrowser component to extract the data table into a separate, reusable component (TasksDataTable) and redesign the selection behavior to provide a more robust and maintainable bulk selection system for task status updates and assignments.

Glossary

  • TaskBrowser: The parent component that manages task filtering, toolbar, and detail panel display
  • TasksDataTable: The new extracted component that handles table rendering, selection, and row interactions
  • Selection State: The set of currently selected task rows, tracked by task IDs
  • Bulk Actions: Operations performed on multiple selected tasks simultaneously (status update, assignment)
  • Context Menu: Right-click menu that appears when user right-clicks on selected rows
  • Row Selection: The mechanism for selecting one or more table rows using click, Shift+click, Ctrl+click, or select-all checkbox

Requirements

Requirement 1: Extract Data Table Component

User Story: As a developer, I want the data table logic separated from the TaskBrowser component, so that the code is more maintainable and the table can be reused in other contexts.

Acceptance Criteria

  1. WHEN the TaskBrowser component is refactored THEN the system SHALL create a new TasksDataTable component that encapsulates all table rendering logic
  2. WHEN the TasksDataTable component is created THEN the system SHALL move all TanStack Table configuration, column definitions, and table rendering from TaskBrowser to TasksDataTable
  3. WHEN the TasksDataTable receives filtered tasks as props THEN the system SHALL render the table with all existing columns and sorting functionality
  4. WHEN the TaskBrowser uses TasksDataTable THEN the system SHALL pass filtered tasks, column visibility, and event handlers as props
  5. WHEN a user interacts with the table THEN the system SHALL emit events from TasksDataTable to TaskBrowser for row clicks, double-clicks, and context menu actions

Requirement 2: Redesign Selection State Management

User Story: As a developer, I want selection state managed with a clearer index-based approach, so that bulk operations are more reliable and easier to debug.

Acceptance Criteria

  1. WHEN the selection system is redesigned THEN the system SHALL maintain selection state using task IDs as the primary key
  2. WHEN tasks are filtered or sorted THEN the system SHALL preserve valid selections and remove selections for tasks no longer in the filtered set
  3. WHEN the TasksDataTable manages selection THEN the system SHALL expose selected task IDs through an emitted event or v-model binding
  4. WHEN selection state changes THEN the system SHALL emit a selection-change event with the array of selected task IDs
  5. WHEN the parent component needs selected tasks THEN the system SHALL compute the selected tasks array from the selection state and filtered tasks

Requirement 3: Implement Robust Row Selection Behavior

User Story: As a user, I want intuitive row selection with keyboard modifiers, so that I can efficiently select multiple tasks for bulk operations.

Acceptance Criteria

  1. WHEN a user clicks a row without modifiers THEN the system SHALL clear all selections and select only the clicked row
  2. WHEN a user Ctrl+clicks (or Cmd+clicks on Mac) a row THEN the system SHALL toggle that row's selection state without affecting other selections
  3. WHEN a user Shift+clicks a row THEN the system SHALL select all rows between the last clicked row and the current row
  4. WHEN a user clicks the header checkbox THEN the system SHALL toggle selection of all visible (filtered) rows
  5. WHEN a user double-clicks a row THEN the system SHALL open the task detail panel without modifying selection state

Requirement 4: Preserve Selection During Context Menu Operations

User Story: As a user, I want my selection preserved when I right-click and perform bulk actions, so that I can perform multiple operations on the same set of tasks.

Acceptance Criteria

  1. WHEN a user right-clicks a selected row THEN the system SHALL preserve the current selection and show the context menu
  2. WHEN a user right-clicks an unselected row THEN the system SHALL add that row to the selection and show the context menu
  3. WHEN a user performs a bulk action from the context menu THEN the system SHALL preserve the selection after the operation completes
  4. WHEN a user closes the context menu without performing an action THEN the system SHALL preserve the current selection
  5. WHEN a bulk operation fails THEN the system SHALL preserve the selection so the user can retry

Requirement 5: Clear Selection on Filter Changes

User Story: As a user, I want selections cleared when I change filters, so that I don't accidentally perform bulk operations on tasks I can no longer see.

Acceptance Criteria

  1. WHEN a user changes the status filter THEN the system SHALL clear all row selections
  2. WHEN a user changes the type filter THEN the system SHALL clear all row selections
  3. WHEN a user changes the episode filter THEN the system SHALL clear all row selections
  4. WHEN a user changes the assignee filter THEN the system SHALL clear all row selections
  5. WHEN a user changes the search query THEN the system SHALL clear all row selections

Requirement 6: Maintain Visual Selection Feedback

User Story: As a user, I want clear visual feedback on which rows are selected, so that I know which tasks will be affected by bulk operations.

Acceptance Criteria

  1. WHEN a row is selected THEN the system SHALL apply a distinct background color to the row
  2. WHEN multiple rows are selected THEN the system SHALL apply the same background color to all selected rows
  3. WHEN the user hovers over a row THEN the system SHALL show a hover state that is visually distinct from the selection state
  4. WHEN the header checkbox is in an indeterminate state THEN the system SHALL display the checkbox with an indeterminate visual indicator
  5. WHEN all visible rows are selected THEN the system SHALL display the header checkbox as fully checked

Requirement 7: Support Bulk Status Updates

User Story: As a user, I want to update the status of multiple selected tasks at once, so that I can efficiently manage task workflows.

Acceptance Criteria

  1. WHEN a user selects multiple tasks and chooses a status from the context menu THEN the system SHALL update all selected tasks to the chosen status
  2. WHEN a bulk status update succeeds THEN the system SHALL display a success toast showing the count of updated tasks
  3. WHEN a bulk status update completes THEN the system SHALL refresh the task list to show updated statuses
  4. WHEN a bulk status update fails THEN the system SHALL display an error toast and preserve the selection
  5. WHEN a bulk status update is in progress THEN the system SHALL show a loading indicator

Requirement 8: Support Bulk Task Assignment

User Story: As a user, I want to assign multiple selected tasks to a team member at once, so that I can efficiently distribute work.

Acceptance Criteria

  1. WHEN a user selects multiple tasks and chooses an assignee from the context menu THEN the system SHALL assign all selected tasks to the chosen user
  2. WHEN a bulk assignment succeeds THEN the system SHALL display a success toast showing the count of assigned tasks
  3. WHEN a bulk assignment completes THEN the system SHALL refresh the task list to show updated assignees
  4. WHEN a bulk assignment fails THEN the system SHALL display an error toast and preserve the selection
  5. WHEN a bulk assignment is in progress THEN the system SHALL show a loading indicator

Requirement 9: Maintain Existing TaskBrowser Features

User Story: As a user, I want all existing TaskBrowser features to continue working after the refactor, so that my workflow is not disrupted.

Acceptance Criteria

  1. WHEN the refactor is complete THEN the system SHALL maintain all existing filtering capabilities (status, type, episode, assignee, context, search)
  2. WHEN the refactor is complete THEN the system SHALL maintain the task detail panel functionality for both desktop and mobile views
  3. WHEN the refactor is complete THEN the system SHALL maintain column visibility controls and persistence
  4. WHEN the refactor is complete THEN the system SHALL maintain sorting functionality on all sortable columns
  5. WHEN the refactor is complete THEN the system SHALL maintain the task count and selection count display
