A Rename, references and the like tell the server of every open file of its language first, so a rename reaches files it had not seen and the preview lists them

zls renames only in the documents in its store, and syncDoc told it of a file only when a query was asked from it, so renaming in progress.zig left main.zig unchanged and broken, with no preview. For a query whose answer can reach other files (rename, references, implementation, workspace symbols, calls and type hierarchy), the host snapshots every other open file and the client syncs those its server answers for first. The mock server answers a rename in each document it was told of; lsp-rename-files opens main.rs by a look, renames from lib.rs, and its preview lists both. Co-Authored-By: Claude Opus 5.5

The seam grows a second backend: src/lsp/lsp_client.zig speaks JSON-RPC to child language servers — rust-analyzer, clangd, gopls, tsserver, pyright are rows in a spec table — while the in-process ZLS analyser keeps .zig. One reader thread per server owns the socket, routes responses to a mailbox under the conn mutex (monotonic condvar), answers server-to-client requests, feeds the diagnostics store, and narrates $/progress and state changes through a status sink both native shells post to the transient message row: "rust-analyzer: cargo check 88% 955/1083" lands where a save narrates, with the same clock. Chatty progress is throttled and deduplicated; settled states always land, which is also what makes the goldens deterministic. Nothing wedges and nothing healthy dies: waits are deadline-bounded, a timeout cancels and returns no rows, three consecutive timeouts restart the server ONLY while it is idle (an indexing server is narrating its own excuse), spawn and handshake failures back off 10s to 2min, a crash shortly after ready counts as a failure, and only a missing binary disables a spec. PARDES_LSP_{RS,C,GO,TS,PY} override binaries; empty disables; the snapshot harness pins RS to test/lspmock.zig and empties the rest. Mutating answers really mutate now: the @put record beside rename @edit carries per-range text, so = applies the formatter (both backends) and a same-file WorkspaceEdit rename applies atomically, one undo step, narrated ("renamed 2 range(s)"); a multi-file rename previews as rows instead of half-applying. Malformed responses fail closed: coordinates validated not clamped, one bad TextEdit poisons the whole edit set, poison frames kill the connection instead of buffering forever, decoded control bytes reject a uri, hierarchy items too deep to reserialize are skipped. Four kinds helix does not have, on SPC l: c/C incoming/outgoing calls (rows are call sites), t/T super/subtypes. Pull diagnostics (3.17) preferred when advertised. Help gains a language-keys footer for the motions no builtin row could carry; lsp.rel and look.grep now share one path-shortening rule. zig build lspprobe drives the seam from the CLI (comma-separated kinds share one server); measured against a 1083-crate workspace warm: gd 26ms, gr 213 rows 165ms, incoming calls 212 sites 197ms, document symbols 670 rows 347ms. docs/lsp.md tells the whole story; lsp-evaluation.md gets an addendum.
