Reads context for an open browser session. section=page (default) re-reads the live page: url, form fields, buttons, links and the cleaned DOM. section=map reads the build this session is bound to: the pages, captured calls and candidate functions Writ's earlier rungs found (evidence, not yet verified), plus what has been composed so far. section=lists scans the live page at no AI cost: the repeating rows, their field selectors, which captured request carries them, and a live-tested define_function payload that writ_browser_compose accepts as is, so a guided session opened on a results URL becomes one list/search API with that payload and a save, without probing the page by hand. section=explorer pages through Writ's full recording policy; section=concierge_api pages through the API-builder policy. The policy sections are reference for unusual flows (logins, multi-request chains), not a prerequisite.
