migration code blue app

Migration — Code Blue becomes an App Framework app

Code Blue, the error-log reader, is now an .os.php app (apps/code-blue/) driven by the App Framework instead of a PHP module plus a TypeScript bundle. The window is the same — same id (openstation-code-blue), same desktop icon, same features, same gate — so saved sessions, icon positions and the Developer-mode toggle carry over untouched. What changed is the surface underneath it.

Removed

Surface	Replacement
REST routes GET /desktop-mode/v1/code-blue/sources, GET / DELETE /desktop-mode/v1/code-blue/entries	There are no Code Blue routes. Every interaction is a dispatch: POST /desktop-mode/v1/apps/openstation-code-blue/dispatch with { action, state, args }. To read the window's data from code, call openstation_app_render( 'openstation-code-blue', array( 'range' => 'all' ) ) — it returns the manifest, the state and the rendered body.
Filter openstation_code_blue_window_args	openstation_app_manifest — $manifest['width'], ['icon'], ['title_bar_buttons'], … for $id === 'openstation-code-blue'.
Filter openstation_code_blue_icon_args	The same manifest filter: $manifest['desktop_icon'] (position, pinned).
Filter openstation_code_blue_template_html	openstation_app_response — post-process $response['html'] on every render.
PHP functions openstation_code_blue_parse(), _make_entry(), _log_sources(), _tail(), _read_source(), _user_can_use(), …	Namespaced equivalents in OpenStation\Apps\CodeBlue: parse(), make_entry(), sources( $os ), tail(), read( $os, $source ), can_use( $os ). They are loaded with the app on init @10.
Script handle openstation-code-blue, bundle assets/js/code-blue[.min].js, window.openStationNativeWindows['openstation-code-blue'] published by that bundle	The shared openstation-app-runtime bundle publishes the render callback. Nothing to enqueue.
Style handle openstation-code-blue → assets/css/code-blue.css	openstation-app-openstation-code-blue → apps/code-blue/code-blue.css, still a first-open companion.

Unchanged

• openstation_code_blue_user_can_use, openstation_code_blue_log_sources, openstation_code_blue_entries, openstation_code_blue_environment, openstation_code_blue_max_bytes, openstation_code_blue_max_entries (filters) and openstation_code_blue_log_cleared (action) keep their names and signatures. The environment rows lost their key field; label, value, on remain.
• The Developer-mode + manage_options (manage_network_options on multisite) gate.
• The window id, size, desktop icon, and everything the user sees.

Why

Code Blue was 3,235 lines — 981 PHP, 1,726 TypeScript, 528 CSS — for one window, most of it REST plumbing, registration and imperative DOM painting. As an app it is under half that: the .os.php declares the window and reads the log, the .os.ts paints the body and re-slices it instantly (range, search, sort, legend, expand never leave the browser), and it doubles as the proof that the framework can carry a real window: charts (<os-histogram>), a filterable list, a title-bar button, a ⋯-menu row, a confirm dialog, auto-refresh.
