G6 Host-Bridge Execution Semantics Report

Date: 2026-04-19 Plan: 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
