Metadata

  • Commit message type: feat
  • Scope: tui
  • Branch name prefix: feat/v3.7.0-tui-mainscreen-base-layout

Background and Context

As part of Epic #8086 (TUI MainScreen & Sidebar State Management), the first step is to implement the Textual-based MainScreen base layout. This is the foundation for all other TUI components. The architecture is defined in ADR-044 (TUI Architecture).

This issue blocks Epic #8086.

Expected Behavior

  • Textual MainScreen renders without errors using Textual >= 1.0
  • MainScreen has a proper layout with header, content area, and sidebar regions
  • MainScreen is responsive to terminal resize events
  • MainScreen follows the ADR-044 architecture specification

Acceptance Criteria

  • Textual MainScreen renders without errors using Textual >= 1.0
  • MainScreen has header, content area, and sidebar regions
  • MainScreen is responsive to terminal resize events
  • MainScreen follows ADR-044 architecture specification
  • Widget tests verify MainScreen renders correctly
  • Unit tests achieve >= 97% coverage

Subtasks

  • Create MainScreen class extending textual.app.Screen
  • Implement header region with app title and status indicators
  • Implement content area region for main interaction
  • Implement sidebar region placeholder
  • Handle terminal resize events (on_resize)
  • Write widget tests for MainScreen layout
  • Write unit tests for resize handling

Definition of Done

  1. Textual MainScreen renders correctly
  2. Widget tests verify layout
  3. Unit tests pass with >= 97% coverage
  4. Code reviewed and merged to main branch

[AUTO-OWNR-1] Triage Decision (Cycle 4)

Status: Verified

MoSCoW: Must Have
Priority: Critical
Milestone: v3.7.0

Rationale: MainScreen is the foundational TUI component required by ADR-044 and Epic #8086. All other TUI components depend on this base layout being in place first. Without it, no TUI work can proceed — making this the single most critical v3.7.0 deliverable. Textual >= 1.0 compatibility is a hard requirement per the v3.7.0 spec.

Next Steps: Assign to an implementation worker. Branch feat/v3.7.0-tui-mainscreen-base-layout should be created from master. Implement MainScreen extending textual.app.Screen with header, content area, and sidebar regions. Widget tests and >= 97% unit test coverage required before merge.
