Desktop app silently fails to load plugins that import "bun:sqlite" #41817

Summary

The OpenCode desktop app (1.18.15) loads plugins inside an Electron utilityProcess (Node runtime). The CLI is a Bun binary. The Node plugin host has a Bun-compatible shim for the $ shell but no bun:sqlite module — so any plugin with a runtime bun: import fails to load, and the failure is completely silent.

Repro

~/.opencode/opencode.json:

{ "plugin": [".opencode/plugins/worktree.ts"] }

worktree.ts imports ./worktree/state, and worktree/state.ts:11 does import { Database } from "bun:sqlite" (value import).

Restart the desktop app. The plugin entry appears in the plugins list (the count increments), but its tools never register and no error is visible.

Evidence

• Every successfully imported plugin emits a MODULE_TYPELESS_PACKAGE_JSON warning to server.log. worktree.ts does not — its module graph is never evaluated (verified in ~/.config/ai.opencode.desktop/logs/<ts>/server.log).
• No plugin error in server.log, renderer.log, main.log, or opencode.log.
• Root cause of the silence: load failures call publishPluginError in packages/opencode/src/plugin/index.ts, which only emits a Session.Event.Error. The desktop renderer does not consume that event, so nothing is shown or logged.
• The same plugin works under the CLI (~/.opencode/bin/opencode, Bun) where bun:sqlite is native.
• Loaded-plugin comparison: rtk.ts (type-only import, loads), graphify.js (Node builtins only, loads), worktree.ts (bun:sqlite value import, does not).

Impact

Any bun:sqlite-based plugin — e.g. the kdco/worktree OCX plugin — cannot run in the desktop app. Node 20 (Electron 30) has no node:sqlite either.

Suggested fixes

1. Surface load failures (bug): log the error (stderr / server log) and/or surface it in the desktop UI so users see why a plugin did not load. Today it is invisible.
2. Provide bun:sqlite in the Node host: a shim implementing the API subset plugins use (new Database(path), exec, prepare().get/all/run, close, PRAGMA) backed by sql.js/WASM, or run plugins under a bundled Bun runtime.
