# G6 Host-Bridge Prerequisites Report

> Date: 2026-04-19
> Plan: [2026-04-19-g6-host-bridge-prerequisites-plan.md](D:/data/ideaSpace/rust/sgClaw/claw-new/docs/superpowers/plans/2026-04-19-g6-host-bridge-prerequisites-plan.md)

## Result

This bounded slice isolates one blocked capability:

1. `host-bridge-real-execution-semantics`

## What Was Isolated

The current `G6` gap is not:

1. classification
2. minimum runtime contract shape
3. family preservation

Those are already present.

The remaining blocked capability is narrower:

1. how host bridge actions are invoked during real execution
2. how callback completion is recognized and bounded

## Explicit Non-Goal

This slice does not broaden into:

1. host-runtime platform rebuild
2. `G6` real-sample execution
3. `G8` work

## Follow-Up

The next bounded step is:

1. `G6 host-bridge execution semantics`
