+# Phase 4 Plan 04: Human Verification Summary
+
+**Agent (Teressa) confirmed the complete PDF ingest flow works end-to-end in the browser: forms library, modal, document creation, PDF rendering with page nav and zoom, file storage, and auth guards all verified as functional.**
+
+## Performance
+
+- **Duration:** ~1 min (verification checkpoint — no code changes)
+- **Started:** 2026-03-20T04:04:00Z
+- **Completed:** 2026-03-20T04:04:15Z
+- **Tasks:** 1 (checkpoint:human-verify)
+- **Files modified:** 0 (verification only)
+
+## Accomplishments
+
+- Human agent verified all 7 verification steps pass in the browser
+- Phase 4 PDF ingest declared complete and approved
+- All must_have truths confirmed by tester
+
+## Checkpoint Verification Results
+
+All 7 steps passed as confirmed by human tester (response: "approved"):
+
+| Step | Description | Result |
+|------|-------------|--------|
+| 1 | Seed a test form and confirm seeder output | PASS |
+| 2 | "Add Document" button visible on client profile page | PASS |
+| 3 | Modal opens with searchable forms list; template selection pre-fills name | PASS |
+| 4 | Custom PDF upload via file picker; name pre-fills from filename | PASS |
+| 5 | PDF renders in browser on document detail page; Prev/Next, Zoom In/Out, Download, and Back link all work | PASS |
+| 6 | `uploads/clients/{clientId}/` directory contains .pdf files that persist across server restarts | PASS |
+| 7 | Unauthenticated access to `/api/forms-library` and `/api/documents/[id]/file` returns "Unauthorized" | PASS |
+
+## Must-Haves Confirmed
+
+- Agent can open "Add Document" modal from a client profile page
+- Forms library list appears in the modal (either seeded forms or empty-state message)
+- Agent can search/filter the forms list by name
+- Agent can add a document via template selection and see it appear in the documents list
+- Agent can upload a custom PDF via the file picker and see it appear in the documents list
+- Agent can click a document name and reach the document detail page
+- PDF renders in the browser on the document detail page — pages visible, not blank
+- Page navigation (Prev/Next) and Zoom In/Out controls work
+- Download button downloads the PDF
+
+## Task Commits
+
+This plan is a human verification checkpoint — no code was written. Previous plans' commits provide the implementation:
+
+- `63e5888` feat(04-03): add AddDocumentModal, PdfViewer, and document detail page
+- `7ddb920` docs(04-02): complete PDF API routes plan summary
+- `32e129c` feat(04-02): create POST /api/documents and GET /api/documents/[id]/file routes
+- `e0f180c` feat(04-02): create GET /api/forms-library authenticated template list
+- `c830951` docs(04-01): complete PDF ingest data layer plan summary
+
+## Files Created/Modified
+
+None — this was a verification-only checkpoint plan.
+
+## Decisions Made
+
+- Phase 4 declared complete: all 7 browser verification steps passed without issue
+- No gaps discovered during human testing; no follow-up plans needed before Phase 5
+
+## Deviations from Plan
+
+None - plan executed exactly as written. Human tester confirmed "approved" without identifying issues.
+
+## Issues Encountered
+
+None — verification passed cleanly on first attempt.
+
+## User Setup Required
+
+None - no external service configuration required.
+
+## Next Phase Readiness
+
+Phase 4 complete. Phase 5 (field mapping) is unblocked:
+- `uploads/clients/{clientId}/` directory structure established and confirmed working
+- Relative paths stored in DB (clients/{clientId}/{uuid}.pdf) — Phase 5 can locate documents reliably
+- react-pdf v9 is installed and rendering correctly — Phase 5 field overlay layer can be added on top of existing PdfViewer
+- Document status is "draft" on creation — Phase 5 can advance status as fields are filled
+
+Blockers for later phases (unchanged):
+- WFRMLS vendor enrollment takes 2-4 weeks — start process immediately
+- Phase 6 (Signing Flow) warrants a /gsd:research-phase before planning
+- DNS (SPF/DKIM/DMARC) for teressacopelandhomes.com must be configured before signing links reach real clients
