+## [1.17.4]
+
+### Fixed
+- **An action modal prefilled from an enum-cast column died on `Select::getOptionLabel(): Argument #1 ($value) must be of type string|int|null, App\Enums\Status given`.** `fillFormUsing(fn ($record) => ['status' => $record->status])` is the obvious way to write a prefill, and on a column with an enum cast the attribute is the case object, not its backing value. That object went into the modal's form-data bag untouched: `HasModal::getFormDefaults()` returned `$overrides + $seed` raw, and the bag is written **straight into Livewire state** by the host (`WithActions`, `InteractsWithTableActions`, `WithTable`) — the one seeding path that never passes through the form runtime, whose `StateManager::fill()` has collapsed enums to scalars all along. So the enum reached the field's own render, where `getSelectedOptionLabels()` handed it to a `string|int|null` parameter and PHP fataled — a 500 on opening the modal, before the user could touch anything. Two things were wrong with it beyond the crash: an enum instance cannot round-trip through Livewire state to the browser, and a `<select>` compares its `<option value>` against the scalar key, so even a field that survived the render would have shown nothing selected. `getFormDefaults()` now collapses the whole bag through the canonical `EnumResolver::scalarDeep()` — nested rows and multi-select arrays included — so the seeded state carries backing values, the option matches, and the choice still saves back through the cast. `Select::getSelectedOptionLabels()` normalises its own input the same way as a second line of defence, because its parameter is `mixed` and a host can also write the bag itself (an `$set`, a public property assigned from a model). Core gained no knowledge of `wire-forms` for it: `EnumResolver` is a Foundation resolver core already owns.
+- **A table with a `copyable()` column parked a “Copied!” pill in its top-left corner, from first render.** The feedback pill is one element for the whole page, rendered `hidden` by `copy-assets.blade.php` and shown by the copy controller beside whichever button was pressed. `hidden` did not hide it: the pill also carries `inline-flex`, and Tailwind states the attribute as `[hidden]:where(:not([hidden="until-found"])){display:none}` — `:where()` contributes nothing to specificity, so that rule ties with `.inline-flex` and loses on order, utilities being emitted after preflight. The pill was therefore painted before anything was ever copied, and since it is `position: fixed` with no coordinates until the controller places it, it fell back to its static position: the corner of the table. Tailwind 4.1 hides the damage by marking its own rule `!important`, which is why the workbench previews never showed it and only apps on Tailwind 3.x or 4.0.x saw the stray pill — both inside the support range of ADR 0005. The partial now carries the same scoped rule the fill handle already uses, `[data-copy-feedback][hidden] { display: none; }`, which outranks the utility on its own specificity and so holds whatever Tailwind the consumer builds with. No change to the shipped `wire-core-copy.js`. The `copy-cell` browser driver read `p.hidden` — the IDL property, which reports a fully painted element as hidden — and now reads `getComputedStyle(p).display` on both sides of a copy.

+Closura může vrátit případ enumu rovnou z castovaného atributu (`fn ($record) => ['role' => $record->role]`): naplněný bag každý enum srazí na jeho backing hodnotu, protože právě ta putuje ve stavu Livewiru do prohlížeče a právě proti ní `Select` porovnává hodnoty svých `<option>`.
