G6 Host-Bridge Entry Readiness Design

Date: 2026-04-19 Status: Draft Upstream Report: 2026-04-19-g6-host-bridge-callback-state-verification-report.md

1. Intent

This design defines the next bounded slice after G6 host-bridge callback state verification.

The target is:

G6 host-bridge entry readiness

2. Why This Slice

The callback states are now explicit and their verification priority is explicit.

The next bounded pressure is:

1. determine whether those bounded semantics are sufficient to define a future G6 real-sample entry gate

3. Scope Boundary

This design is limited to entry-readiness modeling only.

It may include:

1. defining bounded readiness criteria for future G6 entry
2. defining which semantic pieces must be present before G6 real-sample execution may be opened

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 readiness plan

5. Exit Condition

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

1. freezes entry-readiness scope
2. defines bounded readiness criteria
3. emits one bounded follow-up plan
