Struct BuffersRenderState 

pub struct BuffersRenderState {
    pub registry: BufferRegistry,
    pub uris: Arc<HashMap<BufferId, Uri>>,
}

Buffer registry’s render-side projection — the list of buffers the editor knows about, independent of which one is currently active.

Per “everything is a buffer” (CLAUDE.md): files, help, oil, file-tree, *messages*, scratch — all are entries in this one index. Active-buffer hot-path state lives in ActiveDocumentRenderState; this sub-state is touched on registry changes only.

Phase 5.8.AF.5 / Slice 3c.final.B (group 1): populated. registry carries a clone of the editor’s [BufferRegistry] — the registry is internally Arc<Mutex<...>>-backed so the clone is one Arc bump and the inner lookups (document_handle, name_of, with_oil, flags_of, kind_of) see the latest editor state without any further publication.

uris mirrors Editor::buffer_uris — published as a fresh HashMap clone per publish since the editor’s field is owned directly. The renderer reads rs.buffers.uris.get(&id) instead of app.editor.buffer_uris.get(&id).

Fields

registry: BufferRegistry

Cloned crate::buffer_registry::BufferRegistry. Wait-free to construct (one Arc bump); inner methods take their own lock for each call.

uris: Arc<HashMap<BufferId, Uri>>

LSP URI per buffer id. Published fresh each tick. For ~10 buffers the clone is sub-µs; if the registry grows large, migrate to Arc<HashMap<...>> on the editor side to collapse the clone into one Arc bump.
