Interface Standard

kumwe/interface-standard supplies 21 portable interface value types, strict owner-bound surface declarations, and deterministic Kumwe Interface Standard 1.0 conformance diagnostics under Kumwe\InterfaceStandard.

PHP 8.5 and mbstring are required. kumwe/contribution supplies ownership and declaration contracts; kumwe/access-control supplies Capability. No direct Access Context dependency is needed by this closure. Composer pins published Contribution 0.1.1 and Access Control 0.1.0. Access Control currently uses its explicit GitHub VCS source because Packagist has not indexed it; independently verify release identities before App adoption.

use Kumwe\Contribution\ContributionOwner;
use Kumwe\InterfaceStandard\SurfaceDefinition;

$surface = SurfaceDefinition::fromArray(
    ContributionOwner::extension('acme/orders'),
    $manifestSurface,
);
$canonicalMetadata = $surface->toArray();

Run php examples/consumer.php for a complete declaration. Parsing enforces exact keys, bounded lists, supported versions, plain-text metadata, and ownership. Admission then reports all semantic errors for actor/area, intent/pattern, required states, customization scope, and responsive priorities. Capability references describe requirements; the host enforces them.

Presentation preference state and persistence, rendering, navigation trees, routes, trust, active-generation admission, and authorization remain host responsibilities. There is no container provider or hidden global registry. The source's three presentation preference types are explicitly excluded.

The complete signatures and invariants are in docs/public-api.md. See architecture, integration, verification, and the migration handoff.

After installing dependencies, run composer check. composer clean-consumer builds a distribution archive and installs it in a new no-dev authoritative-classmap consumer. Unreleased dependencies require explicit local source inputs for preliminary verification, documented in docs/verification.md; these inputs never establish release verification.

Version 0.1.0 is published. The changelog describes the proposed successor; publication and independent verification remain separate gates. The same complete package gate runs on PRs and default-branch commits. See releasing for publication and separate App adoption stages.
