block

Summary

Analytical submodule registration is implemented in index.ts.
`activateAnalyticalSubmodule` is synchronous: VS Code contributions ( commands, activity bar provider, chat participant, webviews, AI commands, mutation hooks ) register synchronously and it returns the submodule immediately.
It does not start indexing; it passes the activity-bar post-paint callback into the provider and the caller starts index activation through first_paint_startup.

Ancestor context

first_paint_startup

The activity-bar HTML shell is assigned synchronously by ["../../packages/extension/src/activity_bar_module/activity-bar-webview-provider.ts"]. Its Svelte app installs the host message listener before mount, then sends the one-shot `ready` handshake from a task queued after its first animation frame. ["../../packages/extension/src/extension/startup-gate.ts"] resolves that handshake once; `IndexService.activate` then discovers bases and syncs. If no view opens, a bounded three-second fallback starts the index without any visible first paint to contend with. Parser services inside each `WorkspaceIndex` are lazy and are created only when a file is actually parsed, not while bases are discovered. The sql. js asm implementation is emitted as a separate lazy vendor bundle, so loading `main.cjs` does not parse the database engine before `activate`.
