# TODO - [x] Replace HTMX+PHP file upload queues with client-side JS - [x] Fix submit button on all forms — add JS/PHP debug logging - [x] Fix file-upload-queue.js: redirect detection broken due to opaque redirect (switched from fetch to XHR for reliable responseURL) - [x] Add `console.log` tracing on JS submit interception - [x] Add `error_log` entry-point logging to all 16 PHP action files - [x] Add double-submit guard (`_xamxamActiveSubmit`)
