+# Phase 6 Plan 03: Signing Page Summary
+
+**Public /sign/[token] route with server-side token enforcement (expired/used/pending states), react-pdf full-scroll viewer, pulsing blue signature field overlays, and sticky progress bar**
+
+## Performance
+
+- **Duration:** 3 min
+- **Started:** 2026-03-20T17:28:18Z
+- **Completed:** 2026-03-20T17:30:54Z
+- **Tasks:** 2
+- **Files modified:** 6
+
+## Accomplishments
+
+- Server component validates JWT + one-time-use before rendering any signing UI — no canvas flash on invalid tokens
+- GET /api/sign/[token] returns expired/used/pending JSON with link_opened + document_viewed audit events logged
+- Full-scroll react-pdf viewer with absolutely-positioned pulsing blue overlay divs on each signature field
+- Sticky progress bar shows "X of Y signatures complete" with jump-to-next scroll and submit button
+- GET /api/sign/[token]/pdf streams prepared PDF authenticated by signing token (no agent session required)
+- npm run build passes cleanly with /sign/[token], /api/sign/[token], /api/sign/[token]/pdf all visible as dynamic routes
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1: GET /api/sign/[token] route — token validation + audit logging** - `e1306da` (feat)
+2. **Task 2: Signing page server component + client PDF viewer + progress bar** - `dcf503d` (feat)
+
+**Plan metadata:** (docs commit — see below)
+
+## Files Created/Modified
+
+- `teressa-copeland-homes/src/app/api/sign/[token]/route.ts` - Public GET route: validates JWT, checks one-time-use, logs audit events, returns expired/used/pending JSON
+- `teressa-copeland-homes/src/app/api/sign/[token]/pdf/route.ts` - Token-authenticated PDF streaming route; path traversal guard on stored relative path
+- `teressa-copeland-homes/src/app/sign/[token]/page.tsx` - Server component: validates token + DB lookups before rendering any client UI; inline ErrorPage for three error states
+- `teressa-copeland-homes/src/app/sign/[token]/_components/SigningPageClient.tsx` - Client PDF viewer: react-pdf Document+Page all pages, pulsing overlay divs, coordinate conversion, signaturesRef for Plan 04
+- `teressa-copeland-homes/src/app/sign/[token]/_components/SigningPageClientWrapper.tsx` - Dynamic import wrapper (ssr:false) for react-pdf browser requirement
+- `teressa-copeland-homes/src/app/sign/[token]/_components/SigningProgressBar.tsx` - Sticky progress bar with jump-to-next and submit button
+
+## Decisions Made
+
+- `SigningPageClientWrapper` created with `dynamic(..., { ssr: false })` — react-pdf requires browser APIs (HTMLCanvasElement, pdfjs worker). Direct import from server component would crash at SSR time.
+- PDF file served via `/api/sign/[token]/pdf` rather than the existing `/api/documents/[id]/file` — the existing file route requires an authenticated agent session; the signing page is intentionally public and authenticates via the signing token.
+- `onFieldClick` is a no-op stub in this plan. Plan 04 will wire up the signature modal and populate `signaturesRef`.
+- `ErrorPage` inlined in `page.tsx` — three simple JSX blocks, not worth a separate file.
+
+## Deviations from Plan
+
+### Auto-fixed Issues
+
+**1. [Rule 2 - Missing Critical] Added SigningPageClientWrapper for SSR-safe dynamic import**
+- **Found during:** Task 2 (server component + PDF viewer)
+- **Issue:** `SigningPageClient` uses `pdfjs.GlobalWorkerOptions.workerSrc = new URL(import.meta.url)` and react-pdf canvas APIs — these cannot run in Next.js SSR. Directly importing the client component from the server page.tsx would throw at build/render time.
+- **Fix:** Created `SigningPageClientWrapper.tsx` as a `'use client'` component that wraps `SigningPageClient` in `next/dynamic(..., { ssr: false })`. `page.tsx` imports the wrapper instead.
+- **Files modified:** `SigningPageClientWrapper.tsx` (new), `page.tsx` (imports wrapper not client directly)
+- **Verification:** `npm run build` passes, no SSR errors
+- **Committed in:** `dcf503d` (Task 2 commit)
+
+---
+
+**Total deviations:** 1 auto-fixed (Rule 2 — missing critical SSR guard)
+**Impact on plan:** Necessary for correctness — react-pdf cannot render server-side. The wrapper is a thin file with no behavior change. No scope creep.
+
+## Issues Encountered
+
+None.
+
+## User Setup Required
+
+None — no external service configuration required for this plan.
+
+## Next Phase Readiness
+
+Phase 6 signing page is visually complete and compiles cleanly:
+- /sign/[token] renders correct error states (expired/used/invalid) server-side before any JS runs
+- Valid tokens render the branded header, full-scroll PDF viewer, pulsing field overlays, and sticky progress bar
+- GET /api/sign/[token] logs audit events; GET /api/sign/[token]/pdf streams the prepared PDF
+- Plan 04 can import `SigningPageClient` and wire up `onFieldClick` + the signature modal + submission POST
+- Plan 04 can populate `signaturesRef.current` with captured signatures and call `setSignedFields`
