 Filament v4 tables default to deferred loading. In Pest/Livewire tests, call `->loadTable()` before any `assertSee()`/`assertCanSeeTableRecords()` on a freshly-mounted component, or the table body won't be in the rendered HTML yet.
 
 For custom-data (`->records()`-backed, non-Eloquent) tables: use `->callTableAction($name, $record, data: [...])` / `->mountTableAction(...)` (not the generic `->callAction()`, which targets page-level actions and misses table header/record actions), and use `->assertMountedActionModalSee(...)` to check `->modalContent()` output — modal content is lazily rendered and won't appear in a plain `->html()`/`->assertSee()` snapshot even after mounting the action. See `[[project_internachi_modular]]`-style module layout in `app-modules/ai-agent`.

+## Custom-data table bulk actions: fetchSelectedRecords(false) still hydrates full rows
+On a `Table::records()`-backed (non-Eloquent) page, `BulkAction::make(...)->fetchSelectedRecords(false)` does NOT skip hydration the way it does for an Eloquent table — the `Collection $records` passed to `->action()` still contains full row arrays (keyed by the record key), not bare ids. Use `$records->keys()->all()` to get just the selected ids; `$records->all()`/`$records->values()` gives you full row data instead. See `ManageSuggestions::deleteSelectedBulkAction()` / `ManageSuggestionMisses::promoteBulkAction()`.

+Also: `BnfexpressAdminClient`'s non-2xx handling (`errorMessage()`) must handle `detail` being a list of `{msg, ...}` objects, not just a string — FastAPI's own request-validation failures (422s) return `detail` in that shape, and casting it straight to `(string)` silently produces the literal "Array".
