`atoms.read`Read an atom by path or UUID with usage_pages projection. Returns metadata. Pass `section` with a heading's plain text to get back only that heading and the blocks under it, down to the next heading at the same or shallower level; the result then also carries `section: { heading, level, matches }`, and everything else on it is the atom's own, so a section can be read and written straight back.

`discovery.list_entities`Browse pages or atoms inside a workspace with faceted filters (tag, author, date range, visibility, metadata containment) and sort by alphabetical, recency, or star count.

`files.list`Browse the workspace as a file tree, one level at a time: directories, pages, atoms, code trees (expanded at their paths) and library entries. Each node names its kind, entity, current revision and digest; `at` holds the entities exactly at `path`. `surface` keeps that surface only. History: files.history.

`search.literal`Exact-substring search over the Markdown projection of pages and atoms — deterministic, unlike hybrid `search.global`. A needle shorter than 3 characters is rejected. Returns one envelope per matched entity, up to 5 hits each as `{ line, col, snippet }`. `case_sensitive` defaults to false; `scope` is workspace \| all_mine \| all_public.

`trees.get`Read a code tree's revision (the current one by default), its metadata and surface, and a page of its entries in path order: path, git mode, size and blob SHA-256, optionally under `path_prefix`. A symlink's blob is its target; a submodule link has no blob and gives its `commit`. With `lane`, `metadata` is the lane's bag if it sets one. Anonymous callers read a public code tree's current one.
