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.
