+# Issue #648 Verification
+
+## Status: ✅ ALREADY IMPLEMENTED
+
+`timmy-home#648` asked for a durable session harvest report for 2026-04-14.
+That repo-side deliverable is already present on `main`.
+
+## Acceptance Criteria Check
+
+1. ✅ Durable report artifact exists
+   - Evidence: `reports/production/2026-04-14-session-harvest-report.md`
+2. ✅ Report preserves the original session ledger and names issue-body drift
+   - Evidence: the report includes `## Delivered PR Ledger`, `## Triage Actions`, `## Blocked / Skip Items`, and `## Current Totals`
+3. ✅ Regression coverage already exists on `main`
+   - Evidence: `tests/test_session_harvest_report_2026_04_14.py`
+4. ✅ Fresh verification passed from a new clone
+   - Evidence: `python3 -m pytest tests/test_session_harvest_report_2026_04_14.py -q` → `4 passed in 0.03s`
+
+## Evidence
+
+### Existing report artifact on main
+- `reports/production/2026-04-14-session-harvest-report.md`
+- The report explicitly references `Source issue: timmy-home#648`
+- The report already records the delivered PR ledger, issue-body drift, triage actions, blocked items, and verified totals
+
+### Existing regression test on main
+- `tests/test_session_harvest_report_2026_04_14.py`
+- The test already locks the report path, required headings, verified PR tokens, and follow-up issue state changes
+
+## Verification Run
+
+From a fresh clone on branch `fix/648`, before adding this verification note:
+
+```text
+python3 -m pytest tests/test_session_harvest_report_2026_04_14.py -q
+....                                                                     [100%]
+4 passed in 0.03s
+```
+
+## Recommendation
+
+Close issue #648 as already implemented on `main`.
+This PR only adds the verification note so the open issue can be closed without redoing the report work.
