G6 Host-Bridge Entry Gate Design

Date: 2026-04-19 Status: Draft Upstream Report: 2026-04-19-g6-host-bridge-entry-readiness-report.md

1. Intent

This design defines the next bounded slice after G6 host-bridge entry readiness.

The target is:

G6 host-bridge entry gate

2. Why This Slice

The semantic readiness criteria are now explicit.

The next bounded pressure is:

1. turn those criteria into a bounded future entry gate without opening real execution

3. Scope Boundary

This design is limited to gate modeling only.

It may include:

1. defining pass/fail gate conditions for a future G6 entry slice
2. defining which readiness criteria are hard blockers
3. defining how the gate narrows later real-sample entry

It must not include:

1. executing a G6 real sample
2. implementing host-runtime directly
3. opening G8
4. reopening G7

4. Target Outcome

The bounded target outcome is one state:

1. one bounded G6 host-bridge entry gate plan

5. Exit Condition

This design is complete when implementation can be bounded to one plan that:

1. freezes gate-model scope
2. defines bounded gate conditions
3. emits one bounded follow-up plan
