+# G1-E Remaining Fail-Closed Closure Report
+
+Date: 2026-04-19
+
+Parent framework: `2026-04-19-scene-skill-102-full-coverage-framework-plan`
+
+Parent route: `Route 4 / G1-E single_request_enrichment closure`
+
+Plan: `2026-04-19-g1e-remaining-fail-closed-closure-plan.md`
+
+## Scope
+
+This report closes the fixed Route 4 bucket:
+
+- `single_request_enrichment` structured fail-closed scenes: `2`
+- Primary blocker: `output_columns`
+- Allowed implementation area: bounded G1-E output column recovery
+
+This run did not update `scene_execution_board_2026-04-18.json`, did not create a new family, and did not begin Route 5.
+
+## Implementation
+
+The analyzer now recovers G1-E output columns from two additional source patterns:
+
+- `qxzndbObj.cols.push([...])`
+- wide `titleList` rows such as `[field, top, middle, order, label]`
+
+This keeps the correction in the G1-E response/merge contract layer. It does not change routing or gate policy.
+
+## Results
+
+| Scene ID | Scene | Baseline | Follow-up | Result |
+| --- | --- | --- | --- | --- |
+| `sweep-013-scene` | `业扩报装质量评价体系` | `B / fail-closed / output_columns` | `A / auto-pass` | resolved |
+| `sweep-068-scene` | `用电报装信息统计列表` | `B / fail-closed / output_columns` | `A / auto-pass` | resolved |
+
+Summary:
+
+- Before: `2` G1-E structured fail-closed scenes
+- Resolved to auto-pass: `2`
+- Remaining Route 4 fail-closed: `0`
+- Route-local coverage delta: `+2`
