G6 Host-Bridge Entry Readiness Plan

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

Plan Intent

This plan executes one bounded next slice:

G6 host-bridge entry readiness

Scope Guardrails

1. do not execute a G6 real sample
2. do not implement host-runtime directly
3. do not open G8
4. do not reopen G7
5. do not open G4 / G5

Workstreams

1. WS1 Freeze entry-readiness scope
2. WS2 Define bounded readiness criteria
3. WS3 Publish one bounded readiness result

Phase 0: Freeze the Boundary

Objective

Lock the plan to entry-readiness only.

Tasks

1. freeze G6 as the only target
2. freeze implementation and real execution as out of scope

Acceptance Criteria

1. no broader host-runtime work begins under this plan

Phase 1: Define Readiness Criteria

Objective

Turn the explicit callback verification model into bounded entry-readiness criteria.

Tasks

1. define which semantics are required before G6 entry can open
2. define which semantics remain optional
3. define the minimal readiness threshold

Acceptance Criteria

1. entry-readiness criteria are explicit and bounded

Phase 2: Publish the Bounded Result

Objective

Turn the readiness model into one bounded next artifact.

Tasks

1. publish the readiness result
2. if needed, publish the next bounded follow-up plan

Acceptance Criteria

1. the next step remains narrower than direct host-runtime implementation
