Structured Fail-Closed Residual 13 Closure Design

Date: 2026-04-19 Status: Draft Parent Framework: docs/superpowers/plans/2026-04-19-scene-skill-102-full-coverage-framework-plan.md Parent Layer: Layer C and Layer D Upstream Asset: tests/fixtures/generated_scene/full_coverage_reconciliation_candidates_2026-04-19.json

Intent

Close or explicitly defer the remaining 13 framework-structured-fail-closed scenes after the 102 full-coverage follow-up sweep.

This design does not update the official execution board. It defines how the remaining residual bucket must be split before any implementation work starts.

Current Residual Bucket

The current residual bucket contains 13 scenes:

Archetype	Count	Direction
paginated_enrichment	4	mainline residual closure
multi_mode_request	2	mainline residual closure
local_doc_pipeline	5	boundary hold or future G8 runtime roadmap
host_bridge_workflow	1	boundary hold or future G6 runtime roadmap
page_state_eval	1	bootstrap target isolation

Fixed Residual Scenes

Scene ID	Scene	Archetype	Reason

Route Mapping

This residual bucket must be split into bounded child work:

1. Residual Route A: G3 / paginated_enrichment residual closure for 4 scenes.
2. Residual Route B: G2 / multi_mode_request residual closure for 2 scenes.
3. Residual Route C: boundary hold decision for local-doc and host-bridge residuals.
4. Residual Route D: bootstrap target isolation for the page-state residual.
5. Residual Route E: follow-up mini sweep and reconciliation candidate refresh.

Guardrails

1. Do not update tests/fixtures/generated_scene/scene_execution_board_2026-04-18.json.
2. Do not add new families.
3. Do not start G4/G5.
4. Do not relax readiness gates.
5. Do not merge boundary runtime work with mainline contract closure.
6. Do not classify local-doc residuals as mainline pass without a separate G8 runtime roadmap.
7. Do not classify host-bridge residuals as mainline pass without a separate G6 runtime roadmap.

Implementation Boundaries

Allowed implementation routes:

1. G3 residual workflow evidence recovery.
2. G2 residual request/response/mode readiness correction.

Decision-only routes:

1. local_doc_pipeline residuals.
2. host_bridge_workflow residual.
3. page_state_eval/bootstrap_target residual.

Completion Criteria

This residual design is complete when:

1. all 13 scenes are assigned to one residual route;
2. the mainline residual routes have bounded implementation plans;
3. boundary and bootstrap residuals have explicit hold/isolate decisions;
4. a follow-up mini sweep plan exists to measure the residual closure delta.
