  • Commit message: feat: implement TUI MainScreen and sidebar state management
  • Branch name: feat/tui-mainscreen-sidebar-state-management

Background and Context

v3.7.0 (M8: TUI Implementation) requires a Textual-based MainScreen with 3 sidebar states (hidden/visible/fullscreen). This is the core TUI shell that all other TUI features build upon. The architecture is defined in ADR-044 (TUI Architecture) and must be followed precisely to ensure consistency across all TUI components.

The MainScreen is the entry point for all user interaction in the TUI. Without it, no other TUI features can be built or tested. The sidebar state management is a foundational UX pattern that must be consistent across all TUI panels. The Dracula theme must be applied at the MainScreen level to cascade to all child components.

Block cursor navigation and the notification system are cross-cutting concerns that must be implemented at the MainScreen level. The notification system in particular is required by many downstream TUI features to communicate success, error, and info states to the user.

Current Behavior

No TUI exists. The application is CLI-only. There is no Textual-based interface, no sidebar, no theme, no block cursor navigation, and no notification system.

Expected Behavior

Textual-based MainScreen renders correctly with 3 sidebar states (hidden/visible/fullscreen). Dracula theme is applied consistently across all TUI components. Block cursor navigation works in all interactive panels. Notification system displays success/error/info messages. MainScreen is responsive to terminal resize events.

Acceptance Criteria

  • Textual MainScreen renders without errors using Textual >= 1.0 (#8761)
  • Sidebar has 3 states: hidden, visible, fullscreen (#8761)
  • Sidebar state transitions work via keyboard shortcuts (#8761)
  • Dracula theme applied consistently across all TUI components
  • Block cursor navigation works in all interactive panels (#8593)
  • Notification system displays success/error/info messages (#8595)
  • MainScreen is responsive to terminal resize events
  • All child issues are closed and merged

Subtasks

  • Implement Textual MainScreen base layout with ADR-044 three-state sidebar — #8761
  • Implement block cursor navigation — #8593
  • Implement notification system — #8595
  • Handle terminal resize events
  • Write widget tests for MainScreen
  • Write integration tests for sidebar state transitions

Child Issues

  • #8761 — feat(tui): implement ADR-044 three-state sidebar and MainScreen architecture (Priority/Critical)
  • #8593 — feat(tui): implement block cursor navigation in all interactive TUI panels
  • #8595 — feat(tui): implement notification system for success/error/info messages
  • #8873 — fix(tui): restore LoadingThrobber widget and tui_throbber integration tests

Parent Legendary

Parent Legendary: #8135 (Legendary: TUI Implementation & User Experience)

Definition of Done

Epic complete when all child issues are closed and TUI MainScreen renders correctly with all 3 sidebar states, Dracula theme, block cursor navigation, notification system, and terminal resize handling all functional.

[AUTO-OWNR-1] Triage Decision

Status: Verified

MoSCoW Priority: Must Have

Rationale: The TUI MainScreen and sidebar shell are the foundation for every other v3.7.0 deliverable—without them none of the TUI milestone work can run.

Milestone: v3.7.0 — M8: TUI Implementation

This issue has been reviewed and verified by the project owner. It is now ready for development.
