1030 *
1031 * Approach:
1032 *
1033 * 1. Hooked on `_admin_menu` priority `-PHP_INT_MAX`, just before
1034 * `admin_menu` fires.
1035 * 2. Walk `$wp_filter['admin_menu']->callbacks`. For each callback,
1036 * reflect on the function to find its declaring file → plugin
1037 * file. If the callback doesn't live in `WP_PLUGIN_DIR`, leave it
1038 * alone (Core's own callbacks).
1039 * 3. Replace the callback in-place with a closure that snapshots
1040 * `$menu` and `$submenu` keys, invokes the original, then diffs
1041 * the globals. Every new top-level slug and every new submenu
1042 * entry gets attributed to that plugin file.
1043 *
1044 * This is the source of truth for plugin → menu ownership because it
1045 * captures menus regardless of slug shape, hook name predictability,
1046 * or whether the plugin shares a render callback. Reflection on the
1047 * page hook (in `openstation_resolve_menu_plugin_file`) is now a
1048 * fallback for the rare cases where the tracker wasn't able to install
1049 * in time.
1050 *
1051 * Idempotent — runs at most once per request via a static `$installed`
1052 * flag.

2244 * separators, which the browser does NOT decode in JS string
2245 * contexts — the resulting iframe load would treat `&#038;path`
