# Host-Bridge Runtime Roadmap Design
|
|
|
|
> Date: 2026-04-19
|
|
> Parent Sequence: `2026-04-19-final-2-residual-child-plan-sequence-plan.md`
|
|
> Fixed Scene: `sweep-085-scene`
|
|
|
|
## Intent
|
|
|
|
Close or narrow the remaining host-bridge runtime residual without resurrecting the old G6 semantics micro-plan chain.
|
|
|
|
## Fixed Scope
|
|
|
|
Only `sweep-085-scene` is in scope.
|
|
|
|
## Minimal Success Definition
|
|
|
|
The scene must either:
|
|
|
|
1. become `framework-auto-pass-candidate`; or
|
|
2. remain `framework-structured-fail-closed` with a narrower named host-bridge runtime hold.
|
|
|
|
## Forbidden Scope
|
|
|
|
1. no general host-runtime transport implementation
|
|
2. no new G6 semantics micro-plan
|
|
3. no changes to G1-E/G2/G3 routes
|
|
4. no new family
