- **`sourcekit/workspace/symbolNames`** — returns a flat, deduplicated
list of every symbol name in the workspace index (source and indexed
system modules). Clients use this to drive their search UI locally.
- **`sourcekit/workspace/symbolInfo`** — given a list of exact symbol
names, returns `WorkspaceSymbolItem` for each occurrence across all
workspaces, for display in the search result list. Source-file symbols
get `SymbolInformation` with a `file://` location. SDK/stdlib symbols
get a `WorkspaceSymbol` with `location: .uri(…)` The client must call
`workspaceSymbol/resolve` after the user selects an SDK/stdlib symbol to
obtain the concrete interface location.
- **`workspaceSymbol/resolve`** — resolves the deferred
`WorkspaceSymbol` location from `sourcekit/workspace/symbolInfo`. Parses
the `?module=` value into `moduleName`/`groupName`, finds a real source
file via `mainFiles(containing:)`, calls `openGeneratedInterface`, and
returns the symbol with `location` replaced by a full
`sourcekit-lsp://generated-swift-interface/` URI + range (or a temp
`file://` path for clients without `workspace/getReferenceDocument`
support).
