User Story:

As a form creator (Maya), in order to process applications using existing workflows, I want to download a completed PDF with Carlos’s submission data mapped onto the original form template

Preconditions:

• A submission exists for a published form (Slice 5)
• Original source PDF is stored in the FormProject

Acceptance Criteria:

• Maya can view a list of submissions for her forms
• Maya can select a submission and download a completed PDF
• The PDF maps submission data onto the original PDF form fields
• All filled fields are legible and correctly positioned
• The completed PDF is visually consistent with the original paper form

Success Metrics:

• Field mapping accuracy: percentage of fields correctly placed in PDF
• PDF generation time < 10 seconds

Notes:

• Closes the PDF-in/PDF-out loop — this is the core value proposition
• At end of Slice 6: full pipeline is complete and demoable
• PDF generation library TBD (pdf-lib, puppeteer, or similar)
• Field mapping uses DataCollectionSpec field names to locate PDF form fields

Definition of Done:

• Acceptance criteria met
• Threat model updated – any new trust boundaries, data flows, or attack surfaces are reflected in catalog/architecture/threat-model.md
• Technical documentation updated – architecture docs and decisions are current
• At least one end-to-end test: upload PDF → extract → fill → generate completed PDF
• Tests pass
• Type checking passes
• CI pipeline green
• Deployed and demoable
