Platform runtime

PAM Native 0.6 adds bounded platform primitives that share the retained runtime instead of building separate execution loops. Every coded kind, state, type, priority, and opcode is an integer-backed enum.

Typed bridge IDL

IdlCompiler validates sequential module, method, and field IDs and generates fingerprinted PHP, Kotlin, Swift, and Rust contracts:

$artifacts = IdlCompiler::compile(file_get_contents('bridge.pam-idl.json'));

Schemas are limited to 1 MiB, 256 modules, 256 methods per module, and 128 fields per method.

Priority scheduler and Suspense

$products = new AsyncResource(
    fn (CancellationToken $token) => $repository->products($token),
    key: 'products',
);
$products->load(TaskPriority::UserBlocking);

return Suspense::make(
    $products->value(),
    content: fn (array $items) => ProductGrid::make($items),
    fallback: ProductSkeleton::make(),
);

Immediate, user-blocking, render, normal, background, and idle tasks run in priority order. Coalescing cancels obsolete work and draining respects a frame budget.

Worklet bytecode

$opacity = Worklet::input()
    ->interpolate(0, 200, 1, 0)
    ->clamp(0, 1);

PNW1 worklets are bounded numeric programs. They cannot call PHP, allocate objects, access global state, or perform I/O.

Virtualization

VirtualizedList, VirtualGrid, and SectionList use Rust layout and native recycling. Heterogeneous cells, grids, inverted/horizontal layouts, stable keys, authored or estimated sizes, bounded prefetch, initial index, and end-reached events are supported without per-frame PHP traffic.

Background work and offline sync

BackgroundJobs stores idempotent work in OfflineMutationQueue. Its snapshot can be persisted with PAM storage or Nitro and restored after process death.

$jobs->dispatch(
    'messages.sync',
    uniqueKey: 'conversation:42',
    payload: ['conversationId' => 42],
);

The queue has typed queued, sending, applied, retry, conflict, and failed states, plus capped exponential backoff, 256 KiB payloads, and 10,000 entries.

Hardware-accelerated Canvas

return Canvas::make()
    ->roundedRectangle(8, 8, 120, 48, 12, 0xFF6750A4)
    ->circle(180, 32, 24, 0xFFFFD23F)
    ->line(8, 80, 220, 80, 4, 0xFF111111);

Android and UIKit render retained vector commands using platform-accelerated drawing. Geometry must be finite; command count and payload size are bounded.

Server-driven UI

Server-driven documents are data, not downloadable PHP:

$tree = ServerDrivenUi::render(
    $document,
    actions: fn (string $name): ?Closure => match ($name) {
        'offer.open' => $this->openOffer(...),
        default => null,
    },
);

Only allowlisted native nodes, numeric styles, and locally resolved actions are accepted. A document cannot name or call PHP classes or functions. Documents are limited to 1 MiB, 10,000 nodes, 64 levels, and 16 KiB text values.
