+# Browser guards mutation registry (#659)
+
+This is the reviewed classification of every mutation witness that still needs a browser.
+The executable limit is `200`; `mutation-gate --check`, `npm run inventory` and the unit
+contract all read this same inventory. A new browser guard must be added deliberately under
+one reason below, and its mutant `because` must explain the concrete browser-only invariant.
+
+Converted witnesses are not listed here: their registry guard names an explicit `node --test`
+suite plus `test/mutation-browser-offload.test.mjs`, and every converted mutant is run once
+to prove that the Node witness actually kills it.
+
+| Category | Count | Why a browser is still required |
+| --- | ---: | --- |
+| Performance threshold | 4 | The witness measures real browser wall-time or frame work; a pure assertion cannot prove the budget. |
+| Browser harness integrity | 4 | The mutation breaks page-error, round-trip or page-registration observation in the browser harness itself. |
+| Paint, cascade and layer composition | 26 | The invariant depends on computed CSS, SVG paint, clipping, stacking or pixels produced by Chromium. |
+| Pointer geometry and trusted interaction | 45 | The invariant depends on hit testing, pointer capture, touch/keyboard dispatch or live DOM geometry. |
+| Responsive DOM layout | 36 | The invariant depends on measured element boxes, responsive breakpoints, native/HA dialog shells or focusable target size. |
+| Custom-element and HA browser lifecycle | 85 | The invariant crosses Lit/custom-element lifecycle, browser storage/events, lazy loading or a complete HA-card state transition. |
+| **Total** | **200 / 200** | Growth above the cap fails `mutation-gate --check`. |
