EJS views sat in CODE_EXTENSIONS with no extractor, so an Express/Node app's templates were counted as code and contributed nothing (the #1689 warning). A .ejs file is HTML with <% %> scriptlets and inline <script> blocks, so feeding the whole file to the JS grammar made it one top-level ERROR.
Add extract_ejs: mask the template down to its JS regions (code-tag and <script> bodies), parse them with the TS grammar, and add the two relationships no JS grammar can see - dynamic import('./X') and the EJS <%- include('partial') %> composition edge, resolved to the real partial file. Wire .ejs into the dispatch, the jsts language family, the JS resolve/cache sets, and the hook source extensions.
