Cannot access protected property Page::$title in Cascade::jsonLd() breadcrumbs

[jimblue]

Bug Description

Cascade::jsonLd() accesses $crumb->title as a property at line 601 of src/Cascade.php:

$breadcrumbs->map(function ($crumb, $index) {
    return [
        '@type' => 'ListItem',
        'position' => $index,
        'name' => $crumb->title,  // ← accesses protected property directly
        'item' => $crumb->absoluteUrl(),
    ];
})

Statamic\Structures\Page::$title is a protected property. In a normal front-end rendering context, the HasAugmentedInstance::__get() magic method intercepts the property access and it works fine. However, when an Entry is serialized from a different context — specifically via json_encode() triggered by Laravel Telescope's ExtractProperties — the __get() interception doesn't apply and PHP throws:

Error: Cannot access protected property Statamic\Structures\Page::$title

Call chain that triggers the bug

1. Telescope's ExtractProperties::from() calls json_encode() on a Statamic Entry object
2. Entry implements JsonSerializable → calls toArray() → toEvaluatedAugmentedArray()
3. This augments the seo field, which triggers SEO Pro's Cascade::get() → Cascade::jsonLd()
4. jsonLd() fetches breadcrumbs via Statamic::tag('nav:breadcrumbs')->fetch()
5. The resulting Page objects have $title as a protected property, causing the error

How to Reproduce

1. Install Laravel Telescope in a Statamic application with SEO Pro
2. Enable json_ld_breadcrumbs: true in resources/addons/seo-pro.yaml
3. Visit any page with breadcrumbs (i.e. any page beyond the homepage)
4. The error is thrown/logged on every such request

Suggested Fix

Change $crumb->title to $crumb->title() on line 601 of src/Cascade.php, calling the public method instead of relying on __get():

- 'name' => $crumb->title,
+ 'name' => $crumb->title(),

Environment

• Statamic: v6.5.0
• SEO Pro: v7.1.1
• Laravel: v12
• PHP: 8.5.3
• Telescope: 5.18.0

Correction on the suggested fix: $crumb->title() won't work because the breadcrumbs can also return Statamic\Entries\Entry objects which don't have a title() method (only Page does).

The correct fix should use get('title') which both Page and Entry support:

- 'name' => $crumb->title,
+ 'name' => $crumb->get('title'),
