* Desktop window content relations — server-side surface. |
| 4 |
* |
| 5 |
* A desktop window may carry a "content identity": the object the |
| 6 |
* page inside it shows ("post 123", "comment 45 of post 123"). The |
| 7 |
* shell groups windows sharing the same root object and draws visual |
| 8 |
* ties between them (see `src/window-links/` and |
| 9 |
* `docs/examples/window-links.md`). |
| 10 |
* |
| 11 |
* This file builds the authoritative identity for admin iframe pages. |
| 12 |
* It runs inside the chromeless iframe request — real admin context, |
| 13 |
* where `get_current_screen()` and the content globals are live — so |
| 14 |
* relations the URL alone can't answer (which post a comment belongs |
| 15 |
* to) resolve server-side and reach the shell via the chromeless |
| 16 |
* bridge's `desktop-mode-content-identity` postMessage. |

* page — the entries the window's title-bar "Related" menu offers: |
| 458 |
* |
| 459 |
* 1. **Comments** — one item opening the Comments screen filtered to |
| 460 |
* this post (`edit-comments.php?p={id}`), with the comment total |
| 461 |
* as a count badge. Only when the post type supports comments AND |
| 462 |
* at least one exists — an empty filtered list is a dead end. |
| 463 |
* 2. **Assigned terms** — one item per term of every public |
| 464 |
* taxonomy, opening that term's edit screen |
| 465 |
* (`term.php?taxonomy={tax}&tag_ID={id}`), grouped per taxonomy. |
| 466 |
* 3. **Media** — one item per associated attachment (featured image, |
| 467 |
* `post_parent`-attached uploads, and `wp-image-{id}` embeds — |
| 468 |
* the same three sources the reference extractor uses), opening |
| 469 |
* the Media Library grid with that item's details modal |
| 470 |
* (`upload.php?item={id}`). Core has no parent-filtered library |
| 471 |
* view, so per-item deep links are the honest navigation. |
| 472 |
* 4. **Linked posts** — one item per internal hyperlink in the |
| 473 |
* content that resolves to another post on this site (same |
| 474 |
* extractor the window ties use), opening that post's editor. |
| 475 |
* Cross-site and external hrefs don't resolve to a post id and |
| 476 |
* are excluded. |
| 477 |
* |
| 478 |
* Built-ins deliberately cover `post` and `page` only; other post |

/** |
| 784 |
* Declare a WP-registered script handle as a window-link renderer |
| 785 |
* provider. |
| 786 |
* |
| 787 |
* Mirrors the unfocus-effect / command script registration pattern: |
| 788 |
* minimum-ceremony PHP opt-in tells the shell which enqueued scripts |
| 789 |
* contribute window-link renderers. The shell injects the script URL |
| 790 |
* into the live-refresh payload so a plugin activated mid-session |
| 791 |
* surfaces its renderer in OS Settings → Effects → Window links |
| 792 |
* immediately, no F5 needed. |
| 793 |
* |
| 794 |
* Renderers themselves are declared JS-side via |
| 795 |
* `wp.desktop.registerWindowLinkRenderer( … )` — the mount callback |
| 796 |
* and label live in the plugin's JavaScript. The built-in |
| 797 |
* `svg-splines` is registered through the very same JS hook (see |
| 798 |
* `src/window-links/renderers/svg-splines.ts`). |
| 799 |
* |
| 800 |
* Example: |
| 801 |
* |
| 802 |
* ```php |
| 803 |
* add_action( 'admin_enqueue_scripts', function () { |
| 804 |
* wp_register_script( |
| 805 |
* 'my-plugin-link-renderer', |
| 806 |
* plugins_url( 'js/link-renderer.js', __FILE__ ), |
| 807 |
* array( 'desktop-mode' ), |
| 808 |
* '1.0.0', |
| 809 |
* true |
| 810 |
* ); |
| 811 |
* wp_enqueue_script( 'my-plugin-link-renderer' ); |
| 812 |
* } ); |
| 813 |
* desktop_mode_register_window_link_renderer_script( 'my-plugin-link-renderer' ); |
| 814 |
* ``` |
| 815 |
* |
| 816 |
* For live unregistration on deactivation, the plugin's JS should set |
| 817 |
* `owner: 'my-plugin-link-renderer'` on each |
| 818 |
* `registerWindowLinkRenderer` call. Otherwise the renderer stays |
| 819 |
* until the next page reload — graceful backwards-compat. |
| 820 |
* |
| 821 |
* @param string $handle WP-registered script handle. |
| 822 |
* @return true|WP_Error `true` on success; `WP_Error` on validation failure. |
