# Native Capability Lab Report

Issued UTC: 2026-06-29T00:00:00Z

This report records the native-web audit route added at `/native.php`.

## Purpose

The lab exposes a local feature probe and a static fallback matrix. It demonstrates feature detection without making core content depend on optional browser APIs.

## Audited surfaces

- Semantic HTML landmarks
- Dialog and disclosure primitives
- Popover-ready patterns
- CSS container queries and view transitions
- Worker-backed canvas and optional Web Audio
- Clipboard enhancement
- Markdown content negotiation
- Experimental WebMCP-style read-only registration

## Constraint

No framework runtime, npm package, Composer package, CDN script, analytics, external font, database, build step, bundler, or transpiler is introduced.
