G6 Host-Bridge Entry Gate Verification Design

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

1. Intent

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

The target is:

G6 host-bridge entry gate verification

2. Why This Slice

The future entry gate is now explicit.

The next bounded pressure is:

1. verify the gate model itself before any later real-sample entry slice is considered

3. Scope Boundary

This design is limited to gate verification only.

It may include:

1. defining bounded verification targets for the hard gate
2. defining how fail-close reasons are checked
3. defining how gate verification narrows later G6 entry work

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 verification plan

5. Exit Condition

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

1. freezes gate-verification scope
2. defines bounded verification targets
3. emits one bounded follow-up plan
