Everything in the atlas

A `SELECT` from a business table has nothing to select from: the database in the page holds the framework's own tables, and nothing can reach outside the browser, so an app that reads a system's data cannot be tried here. Only the UI5 libraries built in are available and a control from anywhere else will not load; what the transpiler cannot compile is reported in the output panel rather than run. State lives in the tab — a reload, and a press of Run, starts over on a fresh database.

The embedded preview needs a system that accepts basic auth: the documentation states that pure SSO or SAML without a basic-auth fallback is not supported, and points at `external` mode, which opens the app in the normal browser with the existing SAP session. On the web only the language half runs; the preview with its proxy, traffic log and screenshot, Ctrl+F3 activation, the render gate, the workspace-wide check and the MCP servers are desktop-only. The agent app tools send nothing until `abap2ui5.agent.enableAppTools` is switched on in User settings, because an event they fire runs as the configured user and changes data on the system for real.

It declares a VS Code engine and binds to the .tabl.ddic file extension, so it does nothing for a table definition opened in another editor, or read from a system rather than from a file on disk.

The class has to be moved by hand: an abapGit pull of the exported ZIP, or a paste into ADT or SE24. The palette is held to the 121 controls of UI5 1.71, and a control inserted by its class name instead comes from whatever UI5 the canvas has loaded, with nothing checking it against 1.71 - *Checks* reports that. An app class that builds no view, or more than one, is refused.

It is not the framework and takes no framework fixes: those belong upstream in abap2UI5, and nothing under `src/`, `downport/`, `output/` and `build/` here is a source file. The build is frozen on pinned commits with no scheduled rebuild, so it does not show what abap2UI5 main does today, samples in subfolders of the samples repository are excluded because they require a real SAP system, and a known upstream transpiler issue leaves `check_on_init( )` always false, so backend-built view XML may not be returned.

Event roundtrips and visual fidelity stay with a live run: the documentation leaves those to the project's MCP server and to [abap2UI5 for VS Code](artifact:abap2ui5-vscode-extension). A class that builds view parts in helper methods without the handle idiom cannot be statically reconstructed, and the render gate is then skipped with a notice while the property gate runs on what was reconstructed. A screenshot is not a preview of the app: nothing round-trips, no event reaches ABAP, and a table filled by a SELECT photographs empty unless a mock JSON file sits beside the source.

Every gate here runs off-system, so what the class does on a real system and what the view does on the oldest UI5 release it has to serve are what the `pitfalls` catalogues carry and no local run can see. It runs abap2UI5 app classes, so ABAP that is not one has nothing here to deploy into. In system mode the sandbox tools are not offered, and an `app_act` event runs on the system as the configured user.

There is no control tree: visibility and enablement are not evaluated, and `set_value( )` is not checked against the bound paths. The frontend `CONFIG` (device, UI5 version, focus, scroll) is not sent at all, so an app that branches on device or theme sees initial values. It drives `z2ui5_cl_ui5_handler` and the draft service, which the README states are not part of abap2UI5's released API in `src/02`, so a core change there can require a change here.
