2961 - *
2962 - * When a `os.<post_type>.changed` broadcast fires AND the
2963 - * current iframe is on a known list page for that post type, we
2964 - * fetch the current URL and replace the iframe's `#wpbody-content`
2965 - * in place. The user sees the new state of the list — restored
2966 - * post appears, deleted media disappears — without the WP loading
2967 - * spinner that `location.reload()` would show.
2968 - *
2969 - * Single-edit pages (`post.php`, `post-new.php`, the HPOS order
2970 - * editor) are deliberately NOT matched: replacing their body would
2971 - * destroy any unsaved Gutenberg/classic-editor state. Plugins that
2972 - * want specific behaviour for those pages can subscribe to the
2973 - * same topic on `document` and handle it themselves.
2974 - *
2975 - * Matching is generic: the current page's "list type" is derived
2976 - * from the URL (`edit.php` → its `post_type` param or `post`,
2977 - * `upload.php` → `attachment`, `edit-comments.php` → `comment`)
2978 - * and compared against the `<type>` captured from any
2979 - * `os.<type>.changed` topic — so every custom post
2980 - * type's `edit.php?post_type=X` screen participates with zero
2981 - * per-type code. Non-`edit.php` list screens (e.g. WooCommerce's
2982 - * HPOS `admin.php?page=wc-orders`) are covered by declarative
2983 - * extra rules, filterable server-side via
2984 - * `openstation_soft_reload_rules`.
2985 - *
2986 - * The fetch carries a custom header so a later phase can serve a
2987 - * minimal partial response if we want to optimise; for now WP
2988 - * returns the full admin page and we just pluck the body.
2989 - *
2990 - * Most WP list-table JS delegates on `document`/`body` and
2991 - * survives the swap. The inline editors don't, so
2992 - * `_openstationReinitListTables()` below re-runs Core's init
2993 - * entry points afterwards. A page needing more than that should

3725 - * Stale-nonce recovery after a session-expiry re-login.
3726 - *
3727 - * When the user's session expires while a chromeless window is
3728 - * open, this iframe does NOT show core's `wp-auth-check` login
3729 - * modal — `openstation_chromeless_suppress_auth_check()` keeps
3730 - * the modal assets out of chromeless requests so the parent
3731 - * shell owns the single prompt for the whole desktop. Detection
3732 - * still works without the modal JS: core attaches the
3733 - * `wp-auth-check` boolean to every heartbeat response
3734 - * server-side, and this iframe's own heartbeat keeps ticking.
3735 - *
3736 - * After re-auth the auth cookie is fresh — but every per-page
3737 - * nonce cached in JS globals (`_wpUpdatesSettings.ajax_nonce`,
3738 - * `commonL10n.nonce`, Gutenberg's `wpApiSettings.nonce`, etc.)
3739 - * was minted under the OLD session and is now rejected by
3740 - * `check_ajax_referer`. WP reports that as "Cookie check
3741 - * failed" on the next plugin Install / Activate / Update click,
3742 - * which is misleading: the cookie is fine; the nonce is stale.
3743 - *
3744 - * Fix: watch jQuery's `heartbeat-tick`. If we ever see
3745 - * `wp-auth-check: false` and then later see the same field flip
3746 - * back to `true`, the user re-authed mid-session and every
3747 - * cached nonce in this iframe is stale — reload so they
3748 - * regenerate from the fresh session. The parent is nudged
3749 - * first (`os-reauth-detected`) so its own recovery
3750 - * (`src/auth-recovery/index.ts`: in-place nonce refresh + a
3751 - * reload sweep over sibling iframes that haven't ticked yet)
3752 - * starts immediately instead of waiting for the parent's
3753 - * heartbeat schedule.
3754 - *

3756 - * pull it for heartbeat already), this block is a no-op.
