Final 2 Residual Child Plan Sequence Design

Date: 2026-04-19 Parent Framework: 2026-04-19-scene-skill-102-full-coverage-framework-plan.md Parent Layer: Layer E / Route 5 + Route 6 Upstream Board State: framework-auto-pass = 100, framework-structured-fail-closed = 2

Intent

Define the remaining bounded plan sequence after local-doc runtime closure. Only two framework structured fail-closed residuals remain:

1. sweep-085-scene: host_bridge_workflow, next action future-host-bridge-runtime-roadmap-input
2. sweep-091-scene: page_state_eval, next action future-bootstrap-target-normalization-roadmap-input

This sequence prevents drift back into prior G6 micro-plans. Every next step must be anchored to this final-2 residual sequence and the 102 full coverage parent framework.

Design Rules

1. Do not reuse the old G6 semantics micro-plan chain as an execution path.
2. Do not start host-bridge and bootstrap work in the same implementation plan.
3. Do not update the official board inside diagnostic or implementation plans.
4. Do not add a new family.
5. Do not modify unrelated mainline contracts for G1-E, G2, or G3.
6. Any implementation must target exactly one residual scene unless a later parent-framework revision expands the fixed input bucket.

Sequence

1. Final 2 Residual Roadmap Prioritization Decide which residual enters implementation first.

2. Bootstrap Target Normalization Roadmap Bounded roadmap for sweep-091-scene, if selected by prioritization.

3. Host-Bridge Runtime Roadmap Bounded roadmap for sweep-085-scene, if selected by prioritization.

4. Final 2 Official Board Reconciliation Refresh Consume the selected roadmap output and update only framework-layer board fields.

5. 102 Framework Closure Rollup Publish the final 102-status view after both residuals are closed or explicitly held.

Expected End State

The target end state is one of:

1. 102 framework-auto-pass, 0 structured fail-closed
2. 101 framework-auto-pass, 1 structured fail-closed with named runtime hold
3. 100 framework-auto-pass, 2 structured fail-closed with named runtime holds

The third state is allowed only if both residuals are explicitly held by bounded decision plans.
