  • Commit message: epic: tui core architecture and a2a integration
  • Branch name: epic/tui-core-architecture-a2a-integration

Background and Context

The v3.7.0 milestone targets full TUI Implementation using the Textual framework. A critical gap exists in the current architecture: the TuiMaterializer A2A integration layer is entirely missing, the TUI shell mode blocks the Textual event loop, multi-session tab management with independent A2A bindings is unimplemented, and the ActorSelectionOverlay.confirm() result is never wired to app._complete_first_run().

This Epic consolidates all TUI core architecture and A2A integration work required to deliver a stable, non-blocking, multi-session TUI for v3.7.0.

Expected Behavior

Upon completion of this Epic:

  • TuiMaterializer has a fully implemented A2A integration layer that routes agent outputs to the correct TUI panels.
  • The TUI shell mode operates asynchronously and does not block the Textual event loop.
  • Multi-session tabs are supported with independent A2A bindings per session.
  • ActorSelectionOverlay.confirm() correctly wires its result to app._complete_first_run().
  • TUI prompt submissions are routed through A2A message/send.
  • First-run actor selection loads from the A2A actor registry.
  • All TUI components pass integration and regression tests.

Acceptance Criteria

  • TuiMaterializer A2A integration layer is implemented and routes outputs correctly (#8442)
  • TUI shell mode is refactored to be non-blocking (async/threaded) and does not stall the Textual event loop (#8441)
  • Multi-session tabs with independent A2A bindings are implemented and functional (#8445)
  • ActorSelectionOverlay.confirm() result is wired to app._complete_first_run() (#8440)
  • TUI prompt submissions are wired through A2A message/send (#8752)
  • First-run actor selection loads from the A2A actor registry (#8751)
  • All child issues are closed with passing tests
  • No regressions in existing TUI flows
  • CI passes on epic/tui-core-architecture-a2a-integration branch

Subtasks

  • Implement TuiMaterializer A2A integration layer — #8442
  • Fix TUI shell mode blocking Textual event loop — #8441
  • Implement multi-session tabs with independent A2A bindings — #8445
  • Wire ActorSelectionOverlay.confirm() to app._complete_first_run() — #8440
  • Wire TUI prompt submissions through A2A message/send — #8752
  • Load first-run actor selection from the A2A actor registry — #8751
  • Integration testing across all TUI components
  • Update TUI architecture documentation

Child Issues

  • #8440 — ActorSelectionOverlay.confirm() result is never wired to app._complete_first_run()
  • #8441 — TUI shell mode blocks Textual event loop
  • #8442 — TuiMaterializer A2A integration layer is missing
  • #8445 — Multi-session tabs with independent A2A bindings not implemented
  • #8751 — Load first-run actor selection from the A2A actor registry
  • #8752 — Wire TUI prompt submissions through A2A message/send

Definition of Done

This Epic should be closed when:

  1. All child issues (#8440, #8441, #8442, #8445, #8751, #8752) are fully resolved and closed.
  2. All acceptance criteria above are checked off.
  3. The TUI core architecture is stable and reviewed.
  4. CI is green on the Epic branch and changes are merged into the v3.7.0 release branch.

[AUTO-OWNR-6] Triage Decision

Status: Verified

MoSCoW: Must Have
Priority: High

Rationale: This Epic consolidates all TUI core architecture and A2A integration work required for the v3.7.0 (M8: TUI Implementation) milestone. The four child issues (#8440, #8441, #8442, #8445) represent foundational gaps — without them the TUI cannot function as a connected, multi-session interface. The Epic is correctly scoped and aligns directly with ADR-044, ADR-045, and ADR-046. Verified as a legitimate, well-defined Epic with clear acceptance criteria and a Definition of Done.

Next Steps: Child issues #8440, #8441, #8442, and #8445 must each be resolved and closed. Implementation should begin with the blocking TuiMaterializer gap (#8442, Priority/Critical) before proceeding to the remaining child issues. Epic branch epic/tui-core-architecture-a2a-integration should be kept in sync with main throughout.
