The chrome-devtools upload_file tool fails on Airtable (uppy dashboard) and some ATS buttons, saying no file chooser was triggered. A dependable fix is to attach a raw CDP session, use Runtime.evaluate to get the objectId of the input[type=file], and call DOM.setFileInputFiles on it. On Ashby the input is #_systemfield_resume. On Airtable, click the attach button first so uppy creates its inputs, target the LAST input.uppy-Dashboard-input, then click its 'Upload 1 file' button. Breezy and Greenhouse both re-render after a resume upload and wipe text fields filled earlier, so upload first and fill afterwards. Breezy is Angular, so the fill tool's value doesn't stick there. Set values with the native HTMLInputElement value setter plus input/change/blur events, then read them back to verify.
