## QA PASSED See QA report document: 1c3bd816-641d-4c7e-b044-5f0e64eacec1 All hypotheses tested and verified: - Attachments section exists in project detail modal - HTMX lazy-loading configured correctly (hx-get, hx-trigger=load, hx-swap=innerHTML) - Network request to /attachments-section endpoint returns 200 OK - Content loads and displays correctly (shows 'No attachments' for empty projects) - No console errors - Proper positioning after Comments section Fix verified working. No issues found.

Implementation complete: ## Changes Made 1. Added HTMX lazy-loading container to server/templates/modals/project_detail.html (line 121-127) 2. Added HTMX lazy-loading container to server/templates/project_detail.html (line 118-124) ## How It Works - Uses hx-get=/web/projects/{{ project.id }}/attachments-section to fetch the attachments section - hx-trigger=load ensures it loads when the modal opens - hx-swap=innerHTML replaces the loading placeholder with the actual content ## Verification - All 98 server tests pass, including 8 attachment-specific tests - Deployed to trckr.roboalch.com - Route /web/projects/{project_id}/attachments-section was already implemented (TRCKR-373) - Template partial attachments_section.html was already created (TRCKR-375) The attachments section appears between the comments section and the detail-meta section in the project detail modal, following the same pattern used for relationships in the issue detail modal.
