Optimal architecture (chosen over the WS+token copy): the ab-connect extension
talks to a local agent-browser native-messaging host. No localhost port, no
token — Chrome authenticates the extension to the host by id. This is the
codex/claude-style "install once, no per-use confirmation" model.
- extensions/ab-connect: rewritten transport WebSocket+token → native messaging
(chrome.runtime.connectNative). Pinned the extension id via a manifest `key`
(→ bdoiejojpjogcjojeladhioioijhgade) so the host manifest can authorize it.
Kept the proven chrome.debugger attach + Target.attachedToTarget emulation;
dropped WS/token/options. Rebranded to "agent-browser connect".
- cli connect.rs: `agent-browser extension install` writes the native-messaging
host manifest (Chrome/Chromium/Edge/Brave) + a launcher; hidden `__nm-host`
speaks the 4-byte-length native-messaging framing.
Validated end-to-end on real Chrome: Chrome spawned the host (origin matched the
pinned id) and the extension attached the user's real logged-in tabs, streaming
Target.attachedToTarget over native messaging — zero token, zero port.
Next: bridge the host to the daemon relay (relay.rs) + CdpClient so
`agent-browser click/eval/...` drives those tabs.
