# 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.
