Boundary Fail-Closed Decision Design

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 5: boundary-family fail-closed Parent Layer: Layer C + Layer D

Intent

Inspect the remaining boundary-family fail-closed records and decide whether they should be:

1. deferred
2. kept as boundary fail-closed
3. opened into one bounded correction slice

This is a decision-first route.

Fixed Input Bucket

1. local_doc_pipeline = 5
2. host_bridge_workflow = 1
3. page_state_eval/bootstrap_target = 1

Allowed Files

1. boundary decision JSON assets
2. boundary decision report assets
3. optional next-plan design/plan files only if a bounded boundary slice is justified

Forbidden Files

1. src/generated_scene/analyzer.rs
2. src/generated_scene/generator.rs
3. tests/fixtures/generated_scene/scene_execution_board_2026-04-18.json

Expected Delta

1. no code-level coverage delta is required
2. the expected result is a decision-quality delta:
   • defer
   • hold
   • open one bounded slice

Stop Rule

Stop after the boundary decision is published.

Do not start boundary implementation under this plan.
