The oven bundler's rewriteImports regex strips ?query suffixes from relative imports, but a stale snapshot on the live oven server is preserving them — packed pieces emit `import * as l5 from "lib/l5.mjs?v=20260330-runtime-support"`, which fails browser import-map resolution since map keys are query-less ("Failed to resolve module specifier"). Cache busting for these built-in modules is already handled by the service worker, the lith deploy hash, and per-bundle blob URLs. Removing the queries makes the bundle robust regardless of which bundler version the oven is running. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
