G2 Remaining Fail-Closed Closure Plan

Date: 2026-04-19 Status: Draft Parent Framework Plan: docs/superpowers/plans/2026-04-19-scene-skill-102-full-coverage-framework-plan.md Parent Route: Route 3: G2 / multi_mode_request Parent Layer: Layer C + Layer D Upstream Design: docs/superpowers/specs/2026-04-19-g2-remaining-fail-closed-closure-design.md

Plan Intent

Implement one bounded correction slice for the remaining Route 3 G2 fail-closed records.

Fixed Input Bucket

multi_mode_request = 4

Allowed Files

1. src/generated_scene/analyzer.rs
2. src/generated_scene/generator.rs
3. src/generated_scene/ir.rs
4. tests/scene_generator_test.rs
5. Route 3 local inventory and report assets

Forbidden Files

1. tests/fixtures/generated_scene/scene_execution_board_2026-04-18.json
2. Route 2 assets
3. Route 4+ assets

Tasks

1. freeze the four Route 3 records
2. confirm the repeated missing contract
3. implement one bounded G2 correction slice
4. rerun bounded validation
5. publish Route 3 delta

Expected Coverage Delta

1. reduce the multi_mode_request fail-closed bucket
2. protect current G2 real-sample pass and canonical stability

Completion Criteria

1. Route 3 bucket has measured before/after status
2. Route 3 is closed or explicitly deferred

Stop Statement

Stop after Route 3 delta is measured.

Do not begin Route 4 under this plan.
