Acceptance Criteria

  • File watcher detects .md changes in dev mode
  • Changed file is re-transformed through the full pipeline (parse → transform → render)
  • Vite module graph is invalidated for the changed file via server.moduleGraph.invalidateModule()
  • Browser receives update (full reload — same approach as existing sveltekit HMR)
  • Level 2 warnings for cross-page runes display in terminal on file change
  • No unnecessary re-transforms of unchanged files in Level 1 mode

Approach

  1. Implement src/hmr.ts — hooks into Vite's configureServer and handleHotUpdate
  2. On .md file change: invalidate module, send full reload
  3. Reference packages/sveltekit/src/content-hmr.ts for existing pattern

Dependencies

  • WORK-094 — core plugin must exist first
