# G6 Host-Bridge Execution Semantics Report

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

## Result

This bounded slice separates the `G6` blocked capability into two explicit semantics:

1. `host-bridge-action-invocation`
2. `callback-request-completion`

## What Was Isolated

The existing generated `G6` runtime shape already exposes two semantic seams:

1. `invokeHostBridge`
2. `callbackEndpoints` and callback result accumulation

So this slice does not treat `G6` as a broad runtime-platform gap anymore.

It treats `G6` as a bounded semantic modeling problem.

## Explicit Non-Goal

This slice does not broaden into:

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

## Follow-Up

The next bounded step is:

1. `G6 host-bridge callback semantics`
