# Startup, Shell, and Content

Primary atlas source:

Current grounded owners:

- `entry` -> CRT bring-up -> `app_bootstrap_main`
- `bootstrap_init_shell_window_services`
- `shell_install_global_controller`
- `shell_service_pump_iteration`
- `shell_dispatch_ui_command`
- `shell_service_frame_cycle`
- `shell_map_file_entry_coordinator`
- `shell_map_file_world_bundle_coordinator`
- `world_entry_transition_and_runtime_bringup`

What this note is for:

- Startup and bootstrap ownership questions
- Shell controller bring-up and frame-cycle ownership
- Shell command or deferred-work routing
- File-flow and content-load boundaries
- World bring-up versus shell-owned cadence questions

Current bounded conclusion:

- No later long-lived gameplay cadence is currently grounded outside the bootstrap-owned shell
  service loop; the local evidence still supports the nested-under-shell reading.
