2700 - *
2701 - * When a `os.<post_type>.changed` broadcast fires AND the
2702 - * current iframe is on a known list page for that post type, we
2703 - * fetch the current URL and replace the iframe's `#wpbody-content`
2704 - * in place. The user sees the new state of the list — restored
2705 - * post appears, deleted media disappears — without the WP loading
2706 - * spinner that `location.reload()` would show.
2707 - *
2708 - * Single-edit pages (`post.php`, `post-new.php`, the HPOS order
2709 - * editor) are deliberately NOT matched: replacing their body would
2710 - * destroy any unsaved Gutenberg/classic-editor state. Plugins that
2711 - * want specific behaviour for those pages can subscribe to the
2712 - * same topic on `document` and handle it themselves.
2713 - *
2714 - * Matching is generic: the current page's "list type" is derived
2715 - * from the URL (`edit.php` → its `post_type` param or `post`,
2716 - * `upload.php` → `attachment`, `edit-comments.php` → `comment`)
2717 - * and compared against the `<type>` captured from any
2718 - * `os.<type>.changed` topic — so every custom post
2719 - * type's `edit.php?post_type=X` screen participates with zero
2720 - * per-type code. Non-`edit.php` list screens (e.g. WooCommerce's
2721 - * HPOS `admin.php?page=wc-orders`) are covered by declarative
2722 - * extra rules, filterable server-side via
2723 - * `openstation_soft_reload_rules`.
2724 - *
2725 - * The fetch carries a custom header so a later phase can serve a
2726 - * minimal partial response if we want to optimise; for now WP
2727 - * returns the full admin page and we just pluck the body.
2728 - *
2729 - * Most WP list-table JS delegates on `document`/`body` and
2730 - * survives the swap. The inline editors don't, so
2731 - * `_openstationReinitListTables()` below re-runs Core's init
2732 - * entry points afterwards. A page needing more than that should
2733 - * listen for `os-soft-reloaded`, which fires after that re-init.

3464 - * Stale-nonce recovery after a session-expiry re-login.
3465 - *
3466 - * When the user's session expires while a chromeless window is
3467 - * open, this iframe does NOT show core's `wp-auth-check` login
3468 - * modal — `openstation_chromeless_suppress_auth_check()` keeps
3469 - * the modal assets out of chromeless requests so the parent
3470 - * shell owns the single prompt for the whole desktop. Detection
3471 - * still works without the modal JS: core attaches the
3472 - * `wp-auth-check` boolean to every heartbeat response
3473 - * server-side, and this iframe's own heartbeat keeps ticking.
3474 - *
3475 - * After re-auth the auth cookie is fresh — but every per-page
3476 - * nonce cached in JS globals (`_wpUpdatesSettings.ajax_nonce`,
3477 - * `commonL10n.nonce`, Gutenberg's `wpApiSettings.nonce`, etc.)
3478 - * was minted under the OLD session and is now rejected by
3479 - * `check_ajax_referer`. WP reports that as "Cookie check
3480 - * failed" on the next plugin Install / Activate / Update click,
3481 - * which is misleading: the cookie is fine; the nonce is stale.
3482 - *
3483 - * Fix: watch jQuery's `heartbeat-tick`. If we ever see
3484 - * `wp-auth-check: false` and then later see the same field flip
3485 - * back to `true`, the user re-authed mid-session and every
3486 - * cached nonce in this iframe is stale — reload so they
3487 - * regenerate from the fresh session. The parent is nudged
3488 - * first (`os-reauth-detected`) so its own recovery
3489 - * (`src/auth-recovery/index.ts`: in-place nonce refresh + a
3490 - * reload sweep over sibling iframes that haven't ticked yet)
3491 - * starts immediately instead of waiting for the parent's
3492 - * heartbeat schedule.
3493 - *
3494 - * If jQuery never loads on this page (rare — most admin screens
3495 - * pull it for heartbeat already), this block is a no-op.
