+# Phase 4 Plan 03: PDF Viewer UI Summary
+
+**react-pdf AddDocumentModal with searchable forms library + file picker, and document detail page with PdfViewer (page nav, zoom, download) wired to the authenticated /api/documents/[id]/file stream**
+
+## Performance
+
+- **Duration:** ~5 min
+- **Started:** 2026-03-20T03:41:23Z
+- **Completed:** 2026-03-20T03:46:00Z
+- **Tasks:** 2
+- **Files modified:** 8
+
+## Accomplishments
+- Installed react-pdf v9 with pdfjs-dist; configured next.config.ts transpilePackages for ESM compatibility
+- Created AddDocumentModal: fetches forms library on open, searchable list, custom PDF file picker, POST to /api/documents
+- Wired "Add Document" button into existing ClientProfileClient — modal state colocated, no server component conversion needed
+- Updated DocumentsTable: document names are now links to /portal/documents/{id}
+- Created PdfViewer: react-pdf Document/Page with Prev/Next, Zoom In/Out, and Download; worker via import.meta.url (no CDN)
+- Created /portal/documents/[docId] page: auth check, Drizzle relational query (with: client), back link to client profile
+- Added documentsRelations + clientsRelations to schema.ts for db.query API support
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1: Install react-pdf and configure Next.js for ESM compatibility** - `63e5888` (feat)
+2. **Task 2: Add Document modal + PDF viewer page** - `c1f60ca` (feat)
+
+**Plan metadata:** (docs commit below)
+
+## Files Created/Modified
+- `teressa-copeland-homes/next.config.ts` - Added transpilePackages: ['react-pdf', 'pdfjs-dist']
+- `teressa-copeland-homes/package.json` - react-pdf added as dependency
+- `teressa-copeland-homes/src/app/portal/_components/AddDocumentModal.tsx` - New: searchable forms library modal with file picker and POST to /api/documents
+- `teressa-copeland-homes/src/app/portal/_components/ClientProfileClient.tsx` - Added isAddDocOpen state, Add Document button in Documents header, AddDocumentModal render
+- `teressa-copeland-homes/src/app/portal/_components/DocumentsTable.tsx` - Document names now wrapped in Link to /portal/documents/{id}
+- `teressa-copeland-homes/src/lib/db/schema.ts` - Added documentsRelations and clientsRelations for Drizzle relational API
+- `teressa-copeland-homes/src/app/portal/(protected)/documents/[docId]/_components/PdfViewer.tsx` - New: react-pdf viewer with page nav, zoom, download
+- `teressa-copeland-homes/src/app/portal/(protected)/documents/[docId]/page.tsx` - New: document detail server page
+
+## Decisions Made
+- react-pdf v9 ships as ESM — `transpilePackages` required in next.config.ts for Next.js webpack to process it
+- pdfjs worker configured via `new URL('pdfjs-dist/build/pdf.worker.min.mjs', import.meta.url)` — CDN URL would fail in offline/Docker environments
+- AddDocumentModal placed in shared `_components/` folder alongside ClientProfileClient — avoids introducing per-route `_components` subdirectory for a shared component
+- documentsRelations needed for `db.query.documents.findFirst({ with: { client: true } })` — Drizzle relational API requires explicit relation definitions in schema
+
+## Deviations from Plan
+
+### Auto-fixed Issues
+
+**1. [Rule 2 - Missing Critical] Added Drizzle relations to schema.ts**
+- **Found during:** Task 2 (document detail page)
+- **Issue:** Plan's DocumentPage uses `db.query.documents.findFirst({ with: { client: true } })` but schema.ts had no relations defined — the relational query would fail at runtime
+- **Fix:** Added `documentsRelations` (one-to-one client) and `clientsRelations` (one-to-many documents) to schema.ts using Drizzle `relations()` helper
+- **Files modified:** `teressa-copeland-homes/src/lib/db/schema.ts`
+- **Verification:** Build compiles successfully with no type errors
+- **Committed in:** `c1f60ca` (Task 2 commit)
+
+**2. [Rule 2 - Missing Critical] DocumentsTable document names made clickable**
+- **Found during:** Task 2 (plan requirement: "document name in client profile links to /portal/documents/{id}")
+- **Issue:** Plan's must_haves stated "Clicking a document name navigates to the document detail page" but existing DocumentsTable had no link on document names
+- **Fix:** Imported Link from next/link, wrapped document name cell content in `<Link href="/portal/documents/{row.id}">` with hover styles
+- **Files modified:** `teressa-copeland-homes/src/app/portal/_components/DocumentsTable.tsx`
+- **Verification:** Build passes; link markup confirmed in component
+- **Committed in:** `c1f60ca` (Task 2 commit)
+
+---
+
+**Total deviations:** 2 auto-fixed (2 missing critical)
+**Impact on plan:** Both auto-fixes were explicitly required by plan's must_haves and action notes. No scope creep.
+
+## Issues Encountered
+None. Build passed cleanly on first attempt after implementing all components.
+
+## User Setup Required
+None - no external service configuration required.
+
+## Next Phase Readiness
+- Agent can open the forms library modal from any client profile page
+- Agent can add a document from the library or via file picker (both code paths wired)
+- New document appears in client's Documents list after modal closes (router.refresh())
+- Clicking any document name navigates to /portal/documents/{docId}
+- Document detail page renders PDF via PdfViewer with full page navigation and zoom
+- Phase 4 Plan 04 (document management: rename, delete, status updates) can build on this UI layer
