Playground
Paste text, see Tier 0 spans, and toggle policy actions - entirely in your browser.
Paste text and watch Tier 0 detection plus policy resolution run in-process. Toggle actions to see how the same spans re-render under a different policy.
Scanning stays in your browser
Tier 0 runs entirely client-side after this page loads. Pasted text is never sent to a server and this page ships no analytics of what you paste. It works offline once loaded.

Blocks use applyBlockAs: "mask" so the demo keeps rendering instead of throwing. Resolved action badges still show block.
In-process Tier 0 · no network on scan · synthetic fixtures only
Scanning is 100% client-side after this page loads. Pasted content is never uploaded, and the page does not ship analytics of what you paste. Once loaded, the playground works offline.
