1042 *
1043 * Approach:
1044 *
1045 * 1. Hooked on `_admin_menu` priority `-PHP_INT_MAX`, just before
1046 * `admin_menu` fires.
1047 * 2. Walk `$wp_filter['admin_menu']->callbacks`. For each callback,
1048 * reflect on the function to find its declaring file → plugin
1049 * file. If the callback doesn't live in `WP_PLUGIN_DIR`, leave it
1050 * alone (Core's own callbacks).
1051 * 3. Replace the callback in-place with a closure that snapshots
1052 * `$menu` and `$submenu` keys, invokes the original, then diffs
1053 * the globals. Every new top-level slug and every new submenu
1054 * entry gets attributed to that plugin file.
1055 *
1056 * This is the source of truth for plugin → menu ownership because it
1057 * captures menus regardless of slug shape, hook name predictability,
1058 * or whether the plugin shares a render callback. Reflection on the
1059 * page hook (in `openstation_resolve_menu_plugin_file`) is now a
1060 * fallback for the rare cases where the tracker wasn't able to install
1061 * in time.
1062 *
1063 * Idempotent — runs at most once per request via a static `$installed`
1064 * flag.

1759 * Post-order depth-first: a handle is emitted only after everything it
1760 * declares, which is the order `WP_Scripts::do_item()` would have
1761 * printed them in. A handle is marked visited *before* its own
1762 * dependencies are walked, so a dependency cycle unwinds instead of
1763 * recursing forever, and an unregistered handle is skipped rather than
1764 * being fatal — it contributes nothing and stops nothing.
1765 *
1766 * **Deliberately not `WP_Dependencies::all_deps()`.** Three reasons,
1767 * each of which has bitten this codebase:
1768 *
1769 * 1. `WP_Scripts::all_deps()` applies `print_scripts_array` to its
1770 * result whenever `$recursion` is falsy. That filter is where the
1771 * chromeless palette trim and the asset guard live, so resolving a
1772 * payload through it would run a print-time trim across a dependency
1773 * list and let the guard splice this plugin's own bundles into it.
1774 * Called from inside one of those filters it is an infinite loop.
1775 *
1776 * 2. Passing `$recursion = true` silences that filter but changes the
1777 * contract: the first handle that fails aborts the entire call
1778 * (`return false`), abandoning every handle after it in the list. The
1779 * caller is left with a `$to_do` that is a truncated prefix of the real
1780 * closure and indistinguishable from a complete one — a silent, partial
1781 * answer conditional on unrelated registrations elsewhere on the page.
1782 * A lazily-delivered bundle resolved that way loses packages it
1783 * declared and throws on an undefined global at mount, which is the
1784 * exact bug this whole mechanism exists to prevent.
1785 *
1786 * 3. `all_deps()` reports missing dependencies through
1787 * `_doing_it_wrong()`. This is read-only analysis; the real print pass
1788 * raises those anyway, and raising them twice turns someone else's
1789 * pre-existing warning into our noise.

1838 * normally resolves a script's dependencies when it enqueues it — the
1839 * packages a bundle declares are on the page before its own body runs.
1840 * A handle that is only ever delivered lazily never goes through that:

1842 * `wp-api-fetch` found `wp.apiFetch` undefined at mount.

1847 * Deferring the palette took the accident away and left the contract
1848 * exposed — see `docs/migration-wp-package-globals.md`.

2029 * injecting a `<link rel="stylesheet">` for every entry whose payload
2030 * carries a `styleUrl`.
2031 *
2032 * Captures both the resolved `src` and any `wp_add_inline_style()`

2101 *
2102 * This builder lets Core do exactly what it would have done — the

2107 * dependency chain on CLONES (the live `$to_do` is never touched).
2108 * Each handle in the chain is harvested into the same

2114 * carry inline data; dropping them would lose middleware and locale
2115 * setup the chain depends on. Handles the boot page already printed

2712 * WC's router never sees `path` and the page renders blank.

2718 * separators, which the browser does NOT decode in JS string
2719 * contexts — the resulting iframe load would treat `&#038;path`
