Host-Bridge Runtime Roadmap Plan

Date: 2026-04-19 Parent Framework: 2026-04-19-scene-skill-102-full-coverage-framework-plan.md Parent Sequence: 2026-04-19-final-2-residual-child-plan-sequence-plan.md Fixed Scene: sweep-085-scene Status: Draft

Plan Intent

Run a bounded host-bridge runtime slice for the single remaining host_bridge_workflow residual.

Fixed Input Bucket

1. sweep-085-scene

Allowed Files

1. src/generated_scene/analyzer.rs
2. src/generated_scene/generator.rs
3. tests/scene_generator_test.rs
4. tests/fixtures/generated_scene/host_bridge_runtime_followup_2026-04-19.json
5. tests/fixtures/generated_scene/host_bridge_runtime_reconciliation_candidates_2026-04-19.json
6. docs/superpowers/reports/2026-04-19-host-bridge-runtime-roadmap-report.md

Forbidden Files

1. tests/fixtures/generated_scene/scene_execution_board_2026-04-18.json

Tasks

1. Freeze the current sweep-085-scene generation report.
2. Identify the exact host-bridge runtime missing piece.
3. Implement at most one bounded correction slice if it can be expressed in generated-scene contract or fail-closed reporting.
4. Rerun only sweep-085-scene.
5. Publish follow-up and reconciliation candidate assets.

Expected Delta

Target delta is +1 framework-auto-pass-candidate if the host-bridge contract can be closed without full runtime transport. Otherwise the delta is 0, with a narrower named runtime hold.

Stop Statement

Stop after the single-scene follow-up and reconciliation candidates are published. Do not update the official board under this plan.
