| 273 | + * Sends plain `/wp-admin/...` requests into the desktop. | |
| 277 | 274 | * |
| 278 | - * Why: the portal honors the saved session's focused window, so a user | |
| 279 | - * who follows a link the portal can't resolve — a network-admin URL, a | |
| 280 | - * path outside the wp-admin allowlist — is better off on their restored | |
| 281 | - * desktop than on a page the shell can't place. | |
| 275 | + * The shell is served by its own screen (`includes/shell-screen.php`), | |
| 276 | + * so a plain admin page is never where the desktop renders: a user who | |
| 277 | + * typed or bookmarked `/wp-admin/edit.php` is forwarded to the shell | |
| 278 | + * screen with that URL as the page it opens first. Three routes out of | |
| 279 | + * here, cheapest first: | |
| 282 | 280 | * |
| 283 | - * Why NOT unconditionally: for the ordinary case the forward is a round | |
| 284 | - * trip to nowhere. The portal resolves `?target=` straight back to the | |
| 285 | - * URL we are already serving and redirects here with | |
| 286 | - * `desktop_mode_portal=1&desktop_mode_portal_intent=1` — a flag pair | |
| 287 | - * every consumer reads as `fromPortal && ! fromPortalIntent`, i.e. as | |
| 288 | - * indistinguishable from no flags at all. Two full WordPress bootstraps | |
| 289 | - * bought nothing. The shell does not need the portal to reach it: it | |
| 290 | - * enqueues on any admin page where {@see openstation_is_enabled()}, and | |
| 291 | - * the address bar is deliberately no longer normalized to | |
| 292 | - * `/openstation/` (see the `history.replaceState` note in | |
| 293 | - * `src/desktop.ts` — the round trip is exactly what made reloads flash). | |
| 294 | - * So {@see openstation_portal_forward_is_redundant()} answers the | |
| 295 | - * portal's question locally and we render in place when the answer is | |
| 296 | - * "right here." | |
| 281 | + * 1. **Straight to the shell screen** when the portal would only hand | |
| 282 | + * this URL back — an allowlisted wp-admin file that is also the | |
| 283 | + * page being served, carrying no query arg the portal would strip | |
| 284 | + * ({@see openstation_portal_forward_is_redundant()}). One | |
| 285 | + * redirect; the portal hop would have cost a WordPress bootstrap | |
| 286 | + * to learn what is already known. `openstation_skip_redundant_portal_forward` | |
| 287 | + * (return false) forces the hop back on for a plugin that hooks | |
| 288 | + * the portal handler for side effects. | |
| 289 | + * 2. **Through `/openstation/?target=…`** otherwise — a network-admin | |
| 290 | + * URL, a path outside the wp-admin allowlist — so the portal can | |
| 291 | + * fall back to the saved session's focused window, which is a real | |
| 292 | + * change of destination the shell can't make from here. | |
| 293 | + * 3. **The frozen-flag alias.** A URL carrying `desktop_mode_portal=1` | |
| 294 | + * is the desktop's pre-screen address: the portal used to forward | |
| 295 | + * to a real admin page tagged with it, and bookmarks, the PWA start | |
| 296 | + * URL and plugin-built links still say so. It goes to the shell | |
| 297 | + * screen with that URL as the target, and `intent=1` when the | |
| 298 | + * intent flag was present. The flags stay frozen (see AGENTS.md); | |
| 299 | + * only what they resolve to moved. | |
| 297 | 300 | * |
| 298 | 301 | * Narrowly scoped to bail on every automated or sub-request entry point |
