# 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`
