+# Phase 7 Plan 03: Full Phase 7 Browser Verification Summary
+
+**All four Phase 7 browser verification criteria passed — agent download, Signed badge, private storage guard, and download-only-for-Signed confirmed working**
+
+## Performance
+
+- **Duration:** < 1 min (human verification checkpoint, no code changes)
+- **Started:** 2026-03-21
+- **Completed:** 2026-03-21
+- **Tasks:** 1 (checkpoint:human-verify)
+- **Files modified:** 0
+
+## Accomplishments
+
+- Human agent verified that the "Download Signed PDF" button appears on Signed documents and that clicking it downloads the actual signed PDF with the drawn signature embedded
+- Human agent confirmed that the Status badge shows "Signed" and the Date Signed column is non-empty on the dashboard for signed documents
+- Human agent confirmed that /uploads/ and /uploads/clients/ return 404 — private storage guard is in effect and files are not accessible via guessable URLs
+- Human agent confirmed that Draft, Sent, and Viewed documents do NOT show a Download Signed PDF button
+
+## Task Commits
+
+No code was changed in this plan — verification only.
+
+1. **Task 1: Full Phase 7 browser verification** — checkpoint:human-verify, approved by human
+
+## Files Created/Modified

+
+## Decisions Made
+
+- Phase 7 declared complete after human confirmation of all 4 browser verification criteria

+
+## Deviations from Plan
+
+None - plan executed exactly as written.
+
+## Issues Encountered
+
+None.
+

+- Phase 7 (Audit Trail and Download) is complete. All v1 signing-related requirements are satisfied.
+- All 28 v1 requirements are mapped and verified complete.
+- Remaining incomplete phases: Phase 2 (Marketing Site) and Phase 5 (PDF Fill and Field Mapping) have open plans, but the core signing flow is production-ready.
+- No blockers for Phase 7 — the full signing ceremony (send, sign, download) is end-to-end verified.
