Summary

The workspace split is real, but the live runtime still depends on partially integrated paths and documented migration gaps. We should finish the extraction so crate boundaries match the actual runtime and there are fewer half-migrated seams.

Scope

• Identify and remove TODO(integrate) / transitional ownership seams in the live runtime
• Reduce duplicated responsibility across tui, cli, app-server, and shared crates
• Move source-of-truth logic out of monolith-era paths where split crates already exist
• Update architecture docs so they describe reality rather than the migration plan

Acceptance Criteria

• Fewer runtime-critical modules are owned only by crates/tui because of temporary migration shortcuts
• Transitional seams in features, streaming, and related runtime wiring are either integrated or removed
• Workspace docs reflect the real source-of-truth modules
• cargo check and relevant tests pass after the refactor

Starting Points

• docs/workspace_migration_status.md
• docs/ARCHITECTURE.md
• crates/tui/src/main.rs
• crates/tui/src/features.rs
• crates/tui/src/tui/streaming.rs
