v0.8.4

Patch Changes

• 6acc64f: - Add biomechanical pointer, scroll, and keyboard pacing (src/human-input.ts, src/human-model.ts) synchronized with GhostCursor (src/ghost-cursor.ts), plus empirical model fitting from the Cloudflare motor calibration obstacle course.
  • Serialize per-tab Input.* and DOM.scrollIntoViewIfNeeded transactions with target freshness checks, and clear root protectedUi when restricted child frames navigate back to ordinary documents.
  • Acknowledge Page.screencastFrame immediately inside the extension service worker and preserve unscaled backing surfaces so ffmpeg crops emulated setViewportSize regions without black compositor padding.
  • Keep Browser Control tab groups expanded, format auto-generated session IDs as 🤖 <site/title>, preserve attached tabs across POST /extension/reload, and reap abandoned relay-owned tabs after the idle TTL.
  • Promote sibling tab bars, top-level <nav> fallback headers, and clickable <tr> cell summaries in snapshot() while preserving mainRoot when Radix/Floating UI portals are open.
• 86fb059: - Preserve about:blank and newly navigated documents during session-page recovery, and clear crash evidence on target replacement and main-frame navigation.
  • Use NodeHttpClient.layerNodeHttp in RelayClient and disable httpServer.requestTimeout so long handoff() and secrets run requests do not fail after five minutes with HeadersTimeoutError.
  • Guard snapshot() when document.body is absent during early navigation, traverse open Shadow DOM controls, include <input type="button|submit|reset"> values in accessible names, and prefer visible button text and native <label> text over title attributes so snapshot refs match Playwright getByRole.
  • Allow session adopt and MCP session_adopt to omit --target-url/--target-index when adopting a single user-attached tab, register screenshotWithLabels() refs for ref(id), bound page.content() with the 5-second read watchdog, and surface pointer-interception blocker warnings.
  • Wait a full 30-second MV3 alarm period plus margin (35s) for a sleeping extension worker to reconnect, explain Node-side window/relative fetch errors in execute, include the file-system reason in execute --file errors, and stage pnpm build:extension outputs atomically.
