+## Mobile verification
+
+Install the mobile workspace from its own frozen lockfile before generating the
+WebView engine or refreshing its payload hash. It uses esbuild 0.25.4 and stock
+xterm; the desktop workspace uses esbuild 0.25.12 and patched xterm. A shared or
+symlinked dependency directory can generate different output while tests still
+appear to pass locally.
+
+```sh
+corepack pnpm@12.0.0 --dir mobile install --frozen-lockfile
+ORCA_BACKGROUND_LAUNCH=1 corepack pnpm@12.0.0 --dir mobile exec vitest run src/terminal/terminal-webview-osc-link-retirement.test.ts src/terminal/terminal-webview-engine.test.ts src/terminal/terminal-webview-payload-hash.test.ts
+```
+
+The clean mobile build produces a 731,870-character document with SHA-256
+`d1448c5931ba8d90c2c43080cb7f51a903d0d3493bc779497f9f65bff8a1c508`.
+The 13 focused WebView checks pass against that build.
