# G2 Remaining Fail-Closed Closure Report

Date: 2026-04-19

Parent framework: `2026-04-19-scene-skill-102-full-coverage-framework-plan`

Parent route: `Route 3 / G2 multi_mode_request closure`

Plan: `2026-04-19-g2-remaining-fail-closed-closure-plan.md`

## Scope

This report closes the fixed Route 3 bucket:

- `multi_mode_request` structured fail-closed scenes: `4`
- Primary blocker: `g2_request_contract` / `request_mode_contract`
- Allowed implementation area: bounded G2 mode request contract closure

This run did not update `scene_execution_board_2026-04-18.json`, did not create a new family, and did not begin Route 4.

## Implementation

The generator now fills empty auto-inferred G2 mode `requestTemplate` values with bounded mode-specific defaults.

Examples:

- `month`: `{ "page": 1, "rows": 20, "tjzq": "month" }`
- `week`: `{ "page": 1, "rows": 20, "tjzq": "week" }`
- `prediction`: `{ "page": 1, "rows": 60, "reportType": "predictionCompute" }`

The fallback is limited to automatically inferred `multi_mode_request` IR. Explicitly provided incomplete `scene_ir_json` remains fail-closed.

## Results

| Scene ID | Scene | Baseline | Follow-up | Result |
| --- | --- | --- | --- | --- |
| `sweep-020-scene` | `供电所线路电量统计` | `C / fail-closed` | `A / auto-pass` | resolved |
| `sweep-023-scene` | `供电质量看板-武威` | `C / fail-closed` | `A / auto-pass` | resolved |
| `sweep-070-scene` | `电量、站损自动采集上报` | `C / fail-closed` | `A / auto-pass` | resolved |
| `sweep-083-scene` | `营销业务管控监测日报表` | `C / fail-closed` | `A / auto-pass` | resolved |

Summary:

- Before: `4` G2 structured fail-closed scenes
- Resolved to auto-pass: `4`
- Remaining Route 3 fail-closed: `0`
- Route-local coverage delta: `+4`
