Wurster Web

Wurster Web is the browser implementation of the portable Wurst runtime. It opens local or HTTP Range-backed WRST v7, serves application resources through a scoped Service Worker and provides the same core PigFS/PigLink/Piglet vocabulary as Desktop.

0.33.2 surface

The distribution in runtime/web/dist/ contains the browser runtime, service worker and universal <wurst-embed> host. A normal site can embed a Wurst with:

<wurst-embed src="./example.wurst"></wurst-embed>

The host streams byte ranges over MessageChannel; consuming sites do not need to install a root Service Worker for every Wurst.

PigFS

Browser PigFS supports mounted paths, ranged reads, streaming writes, stable object IDs and standalone snapshot export. Multiple Views and in-runtime machine clients of the same Child share one revision-coordinated Wurst session.

Piglet and machine access

<wurst-embed> is the human View path. A piglink.headless: true Child may also be reached with wurst.piglet.connect() / invoke() without creating a visible View. Both address the same durable Child session when they refer to the same Wurst.

Parent PigFS/Piglet delegation and isolated relationship semantics match the shared portable contract.

Protection and trust

Wurster Web supports public, partial and WurstKey-sealed application content and verifies WRST.IO Authority chains offline. Browser parity is not yet complete for every Desktop trust/auth feature, personal/shared PigFS UI flow or local platform integration.

Build

npm run runtime:web:build

The output is self-contained and is also packaged as the shared Web embed runtime used by Desktop. Source-fragment copying is not the release contract.
