L7 (lsp-architecture.md §16): which LSP navigation request a mode-owned nav chord (K / gd / gD / gy / gI / gr / gx) wants the host to fire. Pure data — no lsp_types, no lattice-lsp dependency — so it can ride inside the host-owned Effect::Lsp boundary. lsp-mode’s action_handlers() closure returns Effect::Lsp(LspRequest::X); the host’s editor.lsp_request dispatcher maps each arm onto the existing (unchanged) async request substrate (lsp_hover_request / lsp_nav_request / lsp_references_request / do_lsp_follow_link_at_cursor). The handler carries no position — the substrate reads live Editor cursor/scroll, so the popup/jump anchors to the symbol the chord fired on.

Variants

Hover

K – textDocument/hover.

Definition

gd – textDocument/definition.

Declaration

gD – textDocument/declaration.

TypeDefinition

gy – textDocument/typeDefinition.

Implementation

gI – textDocument/implementation.

References

gr – textDocument/references.

FollowLink

gx – follow the textDocument/documentLink covering the cursor.

ReferencesView

LR.2 (2026-08-11): :lsp-references – the same textDocument/references query as Self::References, landing at the editable multibuffer terminus instead of the picker.

A data arm rather than a new Effect variant, per §16’s grain: a further LSP surface adds an arm here, not a host Action, not a renderer classifier entry. The request, cancellation token, anchor stash and wake are the unchanged substrate; only what the drain does with the result differs.

ReferencesViewRefresh

LR.3 (2026-08-11): gr inside a references view — re-run the query at the view’s stored origin and rebuild it in place.

Distinct from Self::ReferencesView because the position it queries is different: this one must NOT read the live cursor. By the time a refresh fires the cursor sits inside the multibuffer, so querying there would ask about whatever symbol happens to be under it — a different question with a plausible-looking answer. The substrate reads the origin the view recorded when it opened.

ReferencesToErrorList

EP.6 (2026-08-11): :lsp-references-to-error-list — the same query, landing in the error list instead of a surface.

A third terminus rather than a cache snapshot: unlike diagnostics there is no standing “current references” state to pull from, so the command must run the query.
