  "summary": "Tested new Volunteer Application PDF feature (backend + frontend) and did regression on other report endpoints. 11/11 backend pytest tests pass. Frontend SM and DC volunteers pages both render 'Application PDF' button (data-testid=application-pdf-<vid>) next to every volunteer name, and clicking triggers a download of application_<code_or_shortId>.pdf via GET /api/reports/volunteer/{vid}/application.pdf. PDF text extraction contains all required labels (Personal Information, Full Name, Father's Name, Mother's Name, Date of Birth, Mobile, Aadhaar Number, Location, District, Block, Bank Details, Bank Name, Account Number, IFSC Code, Registration Timeline, Applied On, Active, Volunteer Code, PENDING/ACCEPTED status). Also verified previously failing xlsx endpoints are now HTTP 200.",
