<ul><li><strong>CRUD TEST (COMPLETE)</strong>: Full Create/Read/Update/Delete test executed via Puppeteer browser — all 6 operations passed with real data and screenshots confirmed</li><li><strong>BUG FIX (CRITICAL)</strong>: linkmanager.controller.php addLink action — validateUrl() was called with $inputs array (containing Link name and Link target), not URL-only fields, causing all Add Link operations to fail with "Link name is not a valid URL" error; fixed to call validateUrl() with a separate $urlInputs array containing only ItemUrl and ExchangeURL</li><li><strong>BUG FIX (HIGH)</strong>: linkmanager.controller.php addLink action — duplicate $type undefined variable on line 278 caused PHP Warning prepended before JSON output, breaking dataType:"json" AJAX parsing so link table never reloaded after successful create; removed duplicate, added null coalescing for $icons</li><li><strong>BUG FIX (MEDIUM)</strong>: inc_links_manager.php — $_REQUEST["siteid"] and $_REQUEST["domainid"] in Add Link modal and Add Category modal lacked null coalescing; PHP notice output was being injected into modal title bar; fixed with ?? empty string</li><li><strong>RESULT</strong>: CREATE Category — SUCCESS (status 201), CREATE Link — SUCCESS (status 201), UPDATE Category — SUCCESS (status 201), UPDATE Link — SUCCESS (status 201), DELETE Link — SUCCESS (status 201 DELETE_OK), DELETE Category — SUCCESS (status 201 DELETE_OK)</li><li>0 JS errors, 0 network failures (4xx/5xx), all 25 screenshots confirmed on disk</li></ul>
